1. BACKGROUND

1.1 Introduction

1.1.1 Delhi International Airport Private Limited (DIAL), was incorporated on 1st March 2006 with Airports Authority of India (AAI) retaining 26% equity stake and balance 74% of equity stake held by members of the GMR Group led Private consortium. The GMR Group led Private consortium currently comprises of GMR Airports Limited (GAL) holding 64% stake and Fraport AG Frankfurt Airport Services Worldwide (Fraport) holding 10% stake. DIAL has informed that, Fraport has proposed to sell its entire 10% shareholding in DIAL to GAL subject to approval from AAI under Clause 2.5(c) of OMDA. As per DIAL, GAL and Fraport have approached AAI for granting its approval under Clause 2.5 (c) of OMDA for sale of Fraport’s 10% shareholding in DIAL to GAL and the same is under process.

1.1.2 On 4th April 2006, DIAL signed the Operation, Management and Development Agreement (OMDA) with AAI and took over the operations of the Indira Gandhi International Airport (IGIA) on 3rd May

2006.

1.1.3 The OMDA has a term of 30 years, with DIAL having a right to extend the agreement for a further period of 30 years, subject to its satisfactory performance under the various provisions governing the arrangement between DIAL and AAI. In addition to OMDA, DIAL also entered into the State Support Agreement (SSA) with GoI on 26th April 2006 which outlined the support from GoI and has also outlined the principles of tariff determination to be adhered to by the economic regulatory body for airports.

Besides OMDA and SSA, the airport operator has also entered into other agreements with the state government and other agencies in order to complete the project and provide various services at the airport.

1.1.4 As per OMDA, AAI granted DIAL the exclusive right and authority, during the term of agreement, to undertake some of the functions of AAI, namely the functions of operations, maintenance, development, design, construction, up-gradation, modernizing, finance and management of the IGI Airport and to perform services and activities constituting aeronautical and non-aeronautical services at the airport.

1.3 Tariff Setting Principles

1.3.1 The Authority is required to discharge its functions specified under Section 13 of the Airports Economic Regulatory Authority of India Act, 2008 (“AERA Act”). The Authority shall determine the Tariff for

the Aeronautical services taking into consideration the following: i. the capital expenditure incurred and timely investment in improvement of airport facilities. ii. the services provided, its quality and other relevant factors.

iii. the cost of improving efficiency. iv. economic and viable operation of major airports. v. revenue received from services other than the Aeronautical services. vi. the concession offered by Central Government in any agreement or memorandum of understanding or otherwise.

vii. Any other factor which may be relevant for the purposes of this Act.

1.3.2 While, in terms of Section 13(1)(a), the Authority is required to take into account the concessions offered by the Central Government, such concessions are not the only factors which are required to be taken into account by the Authority while determining Tariff. The AERA Act mandates the Authority to ensure ‘economic’ and ‘viable’ operation of the major airports. The Hon’ble Supreme Court, while interpreting similar provisions in other sectors has held that the Authority is required to determine tariff in a manner that protects the interest of the developers as well as the users of the facility.

1.3.3 The tariff determination mechanism towards aeronautical charges for IGIA shall be as per the principles set out under Schedule 1 of State Support Agreement (SSA) as stated below:

1) Incentives Based: The Joint Venture Company (JVC) will be provided with appropriate incentives to operate in an efficient manner, optimizing operating cost, maximizing revenue and undertaking

Consultation Paper No: 07/2024-25 Page 24 of 292BACKGROUND investment in an efficient, effective and timely manner and to this end will utilize a price cap methodology as per this Agreement.

2) Commercial: In setting the price cap, AERA will have regard to the need for the JVC to generate sufficient revenue to cover efficient operating costs, obtain the return of capital over its economic life and achieve a reasonable return on investment commensurate with the risk involved.

3) Transparency: The approach to economic regulation will be fully documented and available to all stakeholders, with the Airports and key stakeholders able to make submissions to AERA and with all decisions fully documented and explained.

4) Consistency: Pricing decisions in each regulatory review period will be undertaken according to a consistent approach in terms of underlying principles.

5) Economic Efficiency: Price regulation should only occur in areas where monopoly power is exercised and not where a competitive or contestable market operates and so should apply only to Aeronautical Services. Further in respect to regulation of Aeronautical Services, the approach to pricing regulation should encourage economic efficiency and only allow efficient costs to be recovered through pricing, subject to acceptance of imposed constraints such as the arrangements in the first three years for operations support from AAI.

6) Independence: The AERA will operate in an independent and autonomous manner subject to policy directives of the GOI on areas identified by GOI.

7) Service Quality: In undertaking its role AERA will monitor pre-set performance in respect to service quality performance as defined in the Operations Management Development Agreement (OMDA) and revised from time to time.

8) Master Plan and Major Development Plans: AERA will accept the Master Plan and Major Development Plans as reviewed and commented by the GOI and will not seek to question or change the approach to development if it is consistent with these plans. However, the AERA would have the right to assess the efficiency with which capital expenditure is undertaken.

9) Consultation: The Joint Venture Company will be required to consult and have reasonable regard to the views of relevant major airport users with respect to planned major airport development.

10) Pricing responsibility: Within the overall price cap the JVC will be able to impose charges subject to those charges being consistent with these pricing principles and IATA pricing principles as

revised from time to time including the following:

(i) Cost reflectivity: Any charges made by the JVC must be allocated across users in a manner that is fully cost reflective and relates to facilities and services that are used by Airport users;

(ii) Non-discriminatory: Charges imposed by the JVC are to be non-discriminatory as within the same class of users;

(iii) Safety: Charges should not be imposed in a way as to discourage the use of facilities and services necessary for safety;

(iv) Usage: In general, aircraft operators, passengers and other users should not be charged for facilities and services they do not use.

The specific formula for calculating the Target Revenue which the airport operator is eligible for

recovery is as below:

TR = RB x WACC + OM + D + T -S i i i i i i i Where TR = Target Revenue RB = regulatory base pertaining to Aeronautical Assets and any investments made for the performance of Reserved Activities, etc. which are owned by the JVC, after incorporating efficient

Consultation Paper No: 07/2024-25 Page 25 of 292BACKGROUND capital expenditure but does not include capital work in progress to the extent not capitalized in fixed assets. It is further clarified that working capital shall not be included as part of regulatory base. It is further clarified that penalties and Liquidated Damages, if any, levied as per the provisions of the OMDA would not be allowed for capitalization in the regulatory base. It is further clarified that the Upfront Fee and any pre-operative expenses incurred by the Successful Bidder towards bid preparation will not be allowed to be capitalized in the regulatory base.

WACC = nominal post-tax weighted average cost of capital, calculated using the marginal rate of corporate tax.

OM= efficient operation and maintenance cost pertaining to Aeronautical Services. It is clarified that penalties and Liquidated Damages, if any, levied as per the provisions of the OMDA would not be allowed as part of the operation and maintenance cost.

D = depreciation calculated in the manner as prescribed in Schedule XIV of the Indian Companies Act, 1956. In the event, the depreciation rates for certain assets are not available in the aforesaid Act, then the depreciation rates as provided in the Income Tax Act for such asset as converted to straight line method from the written down value method will be considered. In the event, such rates are not available in either of the Acts then depreciation rates as per generally accepted Indian accounting standards may be considered.

T = corporate taxes on earnings pertaining to Aeronautical Services.

S = 30% of the gross revenue generated by the JVC from Revenue Share Assets. The costs in relation to such revenue shall not be included while calculating Aeronautical Charges.

1.3.4 For the purpose of clarity and convenience, OM as defined above is referred as Aeronautical O&M and T (corporate taxes on earnings pertaining to Aeronautical Services) as defined above has been referred as Aeronautical Taxes, hereinafter in this Consultation Paper.

1.3.5 For the purpose of the tariff determination exercise, the depreciation rates as per the Authority's Order no. 35/2017-18 dated 12th January 2018 along with its Amendment to Order no. 35/2017-18 dated 9th April 2018 have been considered. The useful life of these assets as determined by the Authority also forms the basis for the deprecation of assets as determined by the statutory auditor of DIAL who has mentioned under the schedules in the annual report of DIAL for FY 2024 that the depreciation rates are aligned with the above-mentioned orders of the Authority.

1.3.6 As per the definition provided in the SSA: “Revenue Share Assets” shall mean (a) Non-Aeronautical Assets; and (b) assets required for provision of aeronautical related services arising at the Airport and not considered in revenues from Non- Aeronautical Assets (e.g.: Public Admission Fee).

1.3.7 As per the definition provided in the OMDA: “Non-Aeronautical Assets” shall mean:

1. all assets required or necessary for the performance of Non-Aeronautical Services at the Airport as listed in Part I of Schedule 6 and any other services mutually agreed to be added to the Schedule 6 hereof as located at the Airport (irrespective of whether they are owned by the JVC or any third Entity);

and

Consultation Paper No: 07/2024-25 Page 26 of 292BACKGROUND

2. all assets required or necessary for the performance of Non-Aeronautical Services at the Airport as listed in Part II of Schedule 6 hereof as located at the Airport (irrespective of whether they are owned by the JVC or any third Entity), to the extent such assets (a) are located within or form part of any terminal building; (b) are conjoined to any other Aeronautical Assets, asset included in paragraph (i) above and such assets are incapable of independent access and independent existence; or (c) are predominantly servicing/ catering any terminal complex/cargo complex and shall specifically include all additional land (other than the Demised Premises), property and structures thereon acquired or leased during the Term, in relation to such Non-Aeronautical Assets.

1.4 Base Airport Charges (BAC)

1.4.1 As part of the tariff setting principles which is provided under the SSA, it specifically mentions that the airport operator is eligible to levy at the minimum Base Airport Charges plus 10% from the third year since the Effective Date as aeronautical tariff. The same is as per the Schedule 6 of the SSA. The relevant

extract is as shown below: “1.The existing AAI airport charges (“Base Airport Charges”) will continue for a period of two (2) years from the Effective Date and in the event the JVC duly completes and commissions the Mandatory Capital Projects required to be completed during the first two (2) years from the Effective Date, a nominal increase of ten (10) percent over the Base Airport Charges shall be allowed for the purposes of calculating Aeronautical Charges for the duration of the third (3rd) Year after the Effective Date (“Incentive”). It is hereby expressly clarified that in the event JVC does not complete and commission, by the end of the second (2nd) year from the Effective Date, the Mandatory Capital Projects required to be completed and commissioned, the Incentive shall not be available to the JVC for purposes of calculating Aeronautical Charges for the third (3rd) year after the Effective Date.

2. From the commencement of the fourth (4th) year after the Effective Date and for every year thereafter for the remainder of the Term, Economic Regulatory Authority / GOI (as the case may be) will set the Aeronautical Charges in accordance with Clause 3.1.1 read with Schedule 1 appended to this Agreement, subject always to the condition that, at the least, a permitted nominal increase of ten (10) percent of the Base Airport Charges will be available to the JVC for the purposes of calculating Aeronautical Charges in any year after the commencement of the fourth year and for the remainder of the Term.”

1.4.2 The Base Airport Charges plus 10% hence shall be applicable if the aeronautical tariff that the airport operator is eligible to recover based on the tariff determination exercise as per Schedule 1 of the SSA, is lesser than the aeronautical tariff as per Base Airport Charges plus 10%.

1.5 Sequence of Past Material events in the Tariff determination exercise

1.5.1 Based on the tariff determination principles and taking into consideration the tariff filings of DIAL and its analysis with regards to each of the building blocks, the Authority issued the Tariff Order for the First Control Period on 24th April 2012. The Authority determined a one-time increase of 345.92% on the aeronautical tariff with effect from 15th May 2012 which was implemented by DIAL.

1.5.2 DIAL also filed an appeal on 23rd May 2012 before the Hon’ble Tribunal (AERAAT) challenging the Tariff Order issued by the Authority for the First Control Period on various grounds.

1.5.3 The Hon`ble High Court of Delhi vide its judgement dated 22nd January 2015 passed in Letters Patent Appeal (LPA) No. 670/2014 filed by DIAL vs Union of India and the Authority, allowed DIAL to continue the tariff determined by the Authority for the First Control Period vide Tariff Order dated 24th

Consultation Paper No: 07/2024-25 Page 27 of 292BACKGROUND April 2012 till the disposal of the appeals pending against the said Tariff Order, by the Hon’ble AERAAT.

1.5.4 Based on the tariff determination principles and taking into consideration the tariff filings of DIAL and its analysis with regards to each of the building blocks, the Authority issued the Tariff Order for the Second Control Period on 10th December 2015, wherein a one-time decrease in tariff of 89.40% was determined. The Authority had also granted, as part of the Tariff Order, an additional ARR of Rs. 691.50 Cr to help DIAL meet its cash deficit on account of reduction in tariff. The Tariff Structure and the rate card arrived at by the Authority regarding tariff determination for the Second Control Period were to be applicable from 01st January 2016.

1.5.5 However, the Tariff Order for the Second Control Period could not be implemented from its intended date on account of Hon`ble High Court of Delhi’s judgement dated 22nd January 2015 as mentioned under 1.5.3.

1.5.6 DIAL subsequently filed an appeal on 11th January 2016 before the Hon’ble AERAAT (i.e. TDSAT) challenging the Tariff Order issued by the Authority for the Second Control Period.

1.5.7 The Hon’ble Supreme Court vide its Order Dated 3rd July 2017 vacated the stay on implementation of the Tariff Order for the Second Control Period and directed Hon’ble TDSAT to complete its adjudication on the issues raised.

1.5.8 DIAL implemented the Tariff order for the Second Control Period dated 10th December 2015 with effect from 8th July 2017.

1.5.9 Post implementation of the Tariff Order for the Second Control Period, DIAL approached the Authority with the contention that the aeronautical tariff determined by the Authority have fallen below the Base Airport Charges stipulated in the SSA. DIAL requested the Authority to allow them to levy Base Airport Charges from 8th July 2017, the date when tariff order for the Second Control Period was given effect as per the orders of the Hon’ble Supreme Court.

1.5.10 The Authority vide order dated 19th November 2018, allowed DIAL to levy aeronautical tariff at the rate of BAC + 10% of BAC, with effect from 1st December 2018.

1.5.11 In the meanwhile, Hon’ble TDSAT, vide its order dated 23rd April 2018, decided the AERA Appeal filed by DIAL against the Tariff Order issued by the Authority for the First Control Period. Further, Hon’ble TDSAT, vide its order dated 15th November 2018, decided the AERA Appeal filed by MIAL against the Tariff Order issued by the Authority for the First Control Period.

1.5.12 Based on the tariff determination principles and taking into consideration the MYTP of DIAL for the Third Control Period and its analysis with regards to each of the building blocks, and taking into consideration the Hon’ble TDSAT directions dated 23rd April 2018, 15th November 2018 and 20th March 2020, the Authority issued the Tariff Order for the Third Control Period on 30th December 2020, wherein it was decided to continue with the then prevalent BAC plus 10% as per the terms of Schedule 6 of SSA.

The Authority as part of the tariff determination for the Third Control Period decided to consider the aspect of projected over recovery pending to be trued up (determined as Rs. 1,267 Cr as on 01st April 2019 based on projected regulatory building blocks for the Third Control Period) along with carrying cost at the time of tariff determination for the Fourth Control Period, during which the actual over recovery pending to be trued up for the Third Control Period shall have to be re-assessed based on actuals.

1.5.13 The Authority had also decided to consider compensatory tariff to compensate DIAL towards discontinuance of Fuel Throughput Charges by MoCA vide letter F.No. AV-13030/216/2016-ER dated 08th January 2020 and to recover the same from every embarking passenger. Such compensatory tariff

Consultation Paper No: 07/2024-25 Page 28 of 292BACKGROUND shall also be considered as part of aeronautical revenue and shall be trued up based on actuals at the time of tariff determination for the Fourth Control Period.

1.6 Hon’ble Supreme Court’s Order in respect to the decisions taken by the Authority for the First Control Period

1.6.1 DIAL filed Civil Appeal in the Hon’ble Supreme Court against the Hon’ble TDSAT judgements dated 23rd April 2018 in the matter of the Tariff Order for the First Control Period issued on 24th April 2012.

The Hon’ble Supreme Court pronounced its judgement in this matter on 11th July 2022 post issuance of Tariff Order for the Third Control Period by the Authority.

1.6.2 The Hon’ble Supreme Court vide its judgement dated 11th July 2022, has dismissed the Civil Appeal filed by DIAL against the Hon’ble TDSAT judgement dated 23rd April 2018 except on the issue relating to corporate tax on earnings pertaining to aeronautical services.

1.6.3 As per the decision of the Hon’ble Supreme Court, the corporate taxes on earnings pertaining to Aeronautical services has to be computed based solely on regulatory accounts prepared by the Authority for the Target Revenue. Article 3.1.1 of the SSA mandates that Annual Fee paid/payable to AAI shall not be considered as a cost in relation to provision of Aeronautical Services. Thus, Annual Fee payable by DIAL shall not be treated as an expense while calculating the corporate taxes on earnings pertaining to Aeronautical services.

1.7 Hon’ble TDSAT Order in respect to the decisions taken by the Authority for the Second and Third Control Period

1.7.1 DIAL has filed the Appeals No. 1/2016 and 1/2021, against the Tariff Orders issued by the Authority for the Second and Third Control Period, respectively. The Hon’ble TDSAT vide its judgement dated 21st July 2023 has disposed these Appeals. Additionally, the Hon’ble TDSAT also vide its order dated 06th October 2023 has disposed the Appeals filed by MIAL against the Tariff Orders issued by the Authority for the Second and Third Control Periods. Further, the Hon’ble TDSAT vide its order dated 14th February 2024 has disposed the Appeals filed by GHIAL against the Tariff Order issued by the Authority for the Third Control Period. In all these judgements, certain issues have been decided in favour of the Airport Operators and certain issues have been decided in favour of the Authority. The decisions of the Hon’ble TDSAT decided in favour of the Airport Operators (DIAL, MIAL and GHIAL) have been factored by DIAL in the Multi Year Tariff Proposal (MYTP) submission for the Fourth Control Period.

1.8 Submission of MYTP by DIAL for the Fourth Control Period

1.8.1 DIAL, on 29th May 2024, filed the Multi Year Tariff Proposal (MYTP) for the Fourth Control Period (FY 2025- FY 2029) after factoring the decisions of the Hon’ble TDSAT on various issues and of Hon’ble Supreme Court judgement on the issue of corporate tax pertaining to earnings from Aeronautical services. These decisions have an impact on the True up for the First, Second and Third Control Periods along with treatment of the Regulatory Building Blocks for the Fourth Control Period.

1.8.2 However, the Authority has challenged the decisions of the Hon’ble TDSAT by filing Civil Appeals in the Hon’ble Supreme Court under Section 31 of AERA Act, 2008. These Civil Appeals were opposed by DIAL and MIAL on the ground that AERA, being a Tariff determining Authority, is a quasi-judicial body and therefore, it cannot file Appeal against the judgement of Hon’ble TDSAT which is an appellate Authority.

1.8.3 The Hon’ble Supreme Court vide its judgement dated 18th October 2024 has rejected the contentions of DIAL and MIAL and has held that the appeals filed by the Authority under Section 31 of the AERA Act, 2008, against the Hon’ble TDSAT orders are maintainable on the ground that AERA is a necessary

Consultation Paper No: 07/2024-25 Page 29 of 292BACKGROUND party in the Appeals filed before the Hon’ble TDSAT and the Authority is the custodian of public interest and for protecting public interest it can file Civil Appeal under Section 31 of the AERA Act, 2008. The Hon’ble Supreme Court has now listed these Civil Appeals filed by the Authority for hearing on merit and are pending before Hon’ble Supreme Court for final settlement and thus are sub-judice.

1.8.4 The Authority has carefully examined the issue of implementation of above-mentioned orders of the Hon’ble TDSAT. The Authority has utmost regards for the directions of the Appellate Authority.

However, the Authority has challenged these orders in Hon’ble Supreme Court under section 31 of AERA Act, 2008, and Hon’ble Supreme Court is presently hearing the matter. Thus, the issues raised in the Civil Appeal filed by the Authority are not finally settled and the Hon’ble Supreme Court is seized up of the matter. Therefore, the Authority notes that under such circumstances if it decides to implement the Hon’ble TDSAT order without finally settling the issues before the Hon’ble Supreme Court and increase in tariff is effected considering DIAL’s submissions on the basis of Hon’ble TDSAT judgments for the Fourth Control Period, then it shall lead to a significant increase in Aeronautical tariff which will have to be borne by the Airport users as DIAL will start recovery of increased tariff from the Airport users. If at a later stage, the Civil Appeals filed by the Authority are upheld or decided in its favour, then it will not be possible to refund excess charges collected from the Airport users during this period on account of increase in tariff. Thus, there will be substantial over recovery by the Airport Operator and there is a possibility that if on account of over recovery future tariff gets reduced then again the Airport Operator may claim that over recovery can’t be clawed back on account of levy of minimum charges i.e. BAC + 10%. Due to all these factors, DIAL would have unjust enrichment at the cost of Airport users. All these factors clearly establish that considering DIAL submissions of giving effects to Hon’ble TDSAT judgements without finally settling the issues before Hon’ble Supreme Court, is not in public interest, more so when the Hon’ble Supreme Court is seized up of all these issues and is hearing these Civil Appeals. On the contrary, public interest would be better served if Authority takes decisions on the basis of final decision of Hon’ble Supreme Court of India on these issues.

1.8.5 Considering the above and in public interest, the Authority proposes to continue the tariff determination exercise consistent with the decisions taken in the Tariff Order for the Third Control Period. The final decision with regard to the issues raised by the Authority in the Civil Appeal will be taken once the matter attains finality in the proceedings before the Hon’ble Supreme Court.

1.8.6 The Authority, as mentioned under para 1.6.3 of this Consultation Paper, proposes to implement based on the legal opinion, the Hon’ble Supreme Court judgment dated 11th July 2022 with regard to corporate taxes on earnings pertaining to Aeronautical services and compute the Aeronautical Taxes based on the regulatory accounts by not treating the Annual Fee pertaining to Aeronautical Revenues as an expense while computing the Aeronautical Taxes as per the directions contained in the said judgement of the Hon’ble Supreme Court.

1.8.7 The Authority as part of the tariff determination exercise for the Fourth Control Period has appointed M/s SBI Capital Markets Limited (SBICAPS), as an independent consultant to assess the MYTP submitted by DIAL for the Fourth Control Period. The independent consultant assisted the Authority in verifying the data from various supporting documents submitted by DIAL such as audited financial statements, Fixed Assets Register (FAR), construction contracts, expense register and submissions made on the basis of various judgements of Hon’ble TDSAT and Hon’ble Supreme Court. The independent consultant also assisted the Authority in ensuring that the treatment provided to various Regulatory Building Blocks is consistent with the Authority’s methodology and approach.

1.8.8 The Authority through the independent consultant has requested DIAL to submit the necessary documents for the data with regards to past Control Periods currently submitted as part of True up

Consultation Paper No: 07/2024-25 Page 30 of 292BACKGROUND Exercise and has also requested for the justifications with regards to assumptions considered for the projections with regards to regulatory building blocks for the Fourth Control Period.

1.8.9 The timelines of various submissions made by DIAL with regards to the MYTP for the Fourth Control

Period is as below:

Consultation Paper No: 07/2024-25 Page 35 of 292TRUE UP FOR THE FIRST CONTROL PERIOD

2. TRUE UP FOR THE FIRST CONTROL PERIOD

2.1 Issues raised by DIAL towards True-up for the First Control Period

2.1.1 DIAL in their MYTP for the Fourth Control Period has raised the following issues pertaining to true up

of the First Control Period: • Weighted Average Cost of Capital, • Revenue from Revenue Share Assets, • Aeronautical Taxes.

2.1.2 The issues were raised by DIAL after factoring the decisions of the Hon’ble TDSAT on various issues and of Hon’ble Supreme Court judgement on the issue of corporate tax pertaining to earnings from Aeronautical services.

2.1.3 In view of the Authority’s analysis provided in para 1.8.2 to 1.8.5 of this Consultation Paper, with regard to the issues raised by the Authority in the Civil Appeal against the judgements of the Hon’ble TDSAT, the Authority is of the view that presently it needs to continue the tariff determination exercise consistent with the decisions taken in the Tariff Order for the Third Control Period as the matter is sub-judice before the Hon’ble Supreme Court.

2.1.4 Further, the Authority proposes to implement the Hon’ble Supreme Court judgment dated 11th July 2022 and recompute the Aeronautical Taxes based on the regulatory accounts by not treating the Annual Fee pertaining to Aeronautical Revenues as an expense while computing the Aeronautical Taxes as per the directions contained in the said judgement of the Hon’ble Supreme Court.

2.2 True up of Weighted Average Cost of Capital (WACC) for the First Control Period DIAL’s Submission regarding True up of WACC for the First Control Period as per MYTP for the Fourth Control Period

2.2.1 DIAL as part of MYTP for the Fourth Control Period has submitted that the Return on Refundable Security Deposits (RSD) should be considered at 16.00% which is equivalent to Return on Equity thereby resulting in a WACC at 12.54%. The relevant excerpts from the Hon’ble TDSAT order dated 06th October 2023 in the case of MIAL, which has been quoted in DIAL’s submission are as below:

“Other infrastructure sector regulators such as Petroleum and Natural Gas Regulatory Board (PNGRB) and Tariff Authority for Major Ports (TAMP) where the tariff is regulated have allowed return on capital employed. These regulators do not provide return on the basis of source and associated cost of funds.

Hence, we are of considered opinion that once RSD has been utilised for meeting capital expenditure, it should be treated as a part of Equity Share Capital invested by the appellant in the business and therefore this appellant is entitled to reasonable rate of return treating RSD as equity.

Moreover, RSD raised by the appellant has been deployed for meeting the project cost of the Chhatrapati Shivaji Maharaj International Airport, Mumbai. If this fund is not available with this appellant, they would have been compelled to infuse same amount of equity for the project of Chhatrapati Shivaji Maharaj International Airport, Mumbai.”

2.2.2 DIAL in their MYTP has submitted that Hon’ble TDSAT directed that the funds raised in the form of RSD are in the nature of equity and should have similar cost in the case of MIAL. MIAL has utilized these funds from RSD for development of the project. Similarly, DIAL has also utilized RSD amount for development of the project and hence proposes to consider return on RSD equivalent to return on

Consultation Paper No: 07/2024-25 Page 36 of 292TRUE UP FOR THE FIRST CONTROL PERIOD Equity for the purpose of calculation of WACC. Therefore, DIAL has considered return on RSD as 16% for the purpose of true up for the First Control Period.

2.2.3 Based on the above consideration, DIAL has submitted the revised calculation of WACC for true up of

the First Control Period which is mentioned below:

Table 4: WACC submitted by DIAL for True up of the First Control Period as per MYTP for the Fourth Control Period Particular Cost of Funds Gearing Effective rate Equity 16.00% 27.50% 4.40% Refundable security deposits (RSD) 16.00% 14.82% 2.37% Debt 10.00% 57.69% 5.77% WACC for the First Control Period 12.54% Decisions taken by the Authority regarding True up of WACC for the First Control Period as per Tariff Order for the Third Control Period

2.2.4 The Authority vide decision No. 2.8.1 of the Tariff Order for the Third Control Period decided to true up WACC based on the cost of equity of 16%, cost of debt of 10% and cost of RSD at the cost of debt (i.e.) 10% based on the recommendation of the independent study. The recalculated WACC for the First Control Period is 11.65%.

Authority’s Examination and Proposals regarding issues pertaining to WACC for True up of the First Control Period as part of the tariff determination exercise for the Fourth Control Period

2.2.5 The Authority consistent with the decision taken during the tariff determination for the Third Control Period proposes to consider cost of equity and cost of debt of 16% and 10% respectively for the purpose of true up of WACC for the First Control Period.

2.2.6 The Authority noted the submission of DIAL regarding the return on RSD component utilized to fund the Project.

2.2.7 As mentioned in para 2.1.3 of this Consultation Paper, the Authority proposes to retain the decisions taken at the time of tariff determination for the Third Control Period i.e. consider cost of RSD at the cost of debt of 10%.

2.2.8 By considering Return on RSD as 10%, WACC for the First Control Period will be the same as that approved by the Authority in the Tariff Order for the Third Control Period. WACC proposed to be

considered by the Authority for True up of the First Control Period is shown in the table below:

Table 5: WACC proposed to be considered by the Authority for True up of the First Control Period FY ending March 31 2010 2011 2012 2013 2014 Cost of Equity 16.00% 16.00% 16.00% 16.00% 16.00% Cost of RSD 10.00% 10.00% 10.00% 10.00% 10.00% Cost of Debt 10.00% 10.00% 10.00% 10.00% 10.00% Equity Proportion 27.50% 27.50% 27.50% 27.50% 27.50% RSD Proportion 14.82% 14.82% 14.82% 14.82% 14.82% Debt Proportion 57.69% 57.69% 57.69% 57.69% 57.69% WACC for the First Control Period 11.65%

2.3 True up of Revenue from Revenue Share Assets for the First Control Period DIAL’s Submissions regarding True up of Revenue from Revenue Share Assets for the First Control Period as per MYTP for the Fourth Control Period

2.3.1 As per the definition mentioned in SSA, Revenue Share Assets are defined as below: "Revenue Share Assets" shall mean (a) Non-Aeronautical Assets; and (b) assets required for provision of aeronautical related services arising at the Airport and not considered in revenues from Non- Aeronautical Assets (e.g. Public admission fee, etc.)”

2.3.2 DIAL in their MYTP for the Fourth Control Period has excluded Other Income, revenue from Existing Assets and Annual fee payable to AAI from the calculation of S Factor. DIAL has followed Hon’ble TDSAT orders dated 21st July 2023 for the Second Control Period and Third Control Period for DIAL,

while computing S factor and the relevant TDSAT order excerpt is shown below:

Other income as part of revenue from revenue share assets “The definition of “Revenue Share Assets” defines “shall mean” meaning thereby to that, it is an exhaustive definition. The definition is not extensive. It would cover only those assets which are defined as Revenue Share Assets. Thus addition is not permissible. This aspect has not been properly appreciated by AERA while treating “other income” as part of revenue, generated from revenue share assets.

In view of the aforesaid reasons, “Other income” cannot be a part of revenue from Revenue Share Assets and consequently, in calculation of “S” factor in target revenue formula which is TR = RB X WACC + OM + D + T – S.

Since other income is not generated from sources allowed under contract, it should not be considered as part of Revenue from Revenue Share Assets.

Annual fee in the calculation of revenue from Revenue Share Assets Annual fee payable to Airport Authority of India (AAI) is not a cost, because the cost is an amount paid to acquire the revenue. Cost is that amount which the entrepreneur pays for procuring the revenue. The cost is an expenditure incurred by any company or firm to produce the goods or services for sale. The cost is an amount that is incurred to earn that revenue prior to such revenue is being earned. Annual fees accrues to AAI after “Revenue” has been earned by DIAL. Hence Annual fee is not included in the calculation of determination of “S” – factor.

“2. Establishment of Escrow Account and Declaration of Trust

2.1 Establishment of the Accounts The Company and the Escrow Bank confirm that the Escrow Bank has established, in the name of the Company at the Escrow Bank's New Delhi branch, an account titled the "Escrow Account". The Escrow Account shall have the following sub accounts, maintained, controlled and operated by the Escrow Bank for the purposes of this Agreement, namely:

(a) a sub account maintained, controlled and operated by the Escrow Bank, titled the "Receivables Account";

(b) a sub account maintained, controlled and operated by the Escrow Bank, titled the "Proceeds Account" which shall have the following sub accounts:

(i) a sub-account maintained, controlled and operated by the Escrow Bank, titled the "Statutory Dues Account”;

Consultation Paper No: 07/2024-25 Page 38 of 292TRUE UP FOR THE FIRST CONTROL PERIOD

(ii) a sub-account maintained, controlled and operated by the Escrow Bank, titled the "AAI Fee Account”; and

(iii) a sub-account maintained, controlled and operated by the Escrow Bank, titled the "Surplus Account".” As per Clause – 3 thereof, it appears that revenue comes in the hands of the JVC only in the “Surplus account”. Clause 3.2 of the Escrow Account Agreement makes it explicitly clear that the revenue meant for this appellant is in “Surplus account”. Thus, out of total “gross revenue”, amount equal to Annual Fee never comes in the hands of or in the account meant for appellant and, therefore, while calculating gross revenue generated by JVC from the Revenue Share Assets, the amount of annual fee ought to be excluded.

Revenue accruing from Existing Assets/ Demised premises considered as part of revenue from Revenue Share Assets “The definition of “Revenue Share Assets”, as stated hereinabove it shall mean a Non-Aeronautical Assets and the assets required for provision of aeronautical related services arising at the Airport and not considered in revenues from Non-Aeronautical Assets. Looking to the definition of Non-Aeronautical Assets, all the assets required or necessary for the performance of Non-Aeronautical Assets at the Airport as listed in Part-I of Schedule – 6 of OMDA as located at the Airport irrespective of whether they are owned by JVC or any third party to the extent such assets are located within or form part of any terminal building or are conjoined to any other Aeronautical assets, asset including in Paragraph

(i) above, and such assets are incapable of independent access and independent existence or are prominently serving/catering any terminal complex/categorically complex and shall specifically include all the additional land (other than demised premises), property and structures thereupon acquired or leased during the Term in relation to such non-aeronautical assets.

Non-Aeronautical Services means such services as are listed in Part- I and Part-II of Schedule – 6 of OMDA. In view of the aforesaid definition of Revenue Share Assets, Non-Aeronautical Assets and Non- Aeronautical Services, it is explicitly clear that Non-Aeronautical Revenue accruing from existing premises/ demised premises could not be considered as part of revenue from “Revenue Share Assets” and consequently it cannot be used for cross subsidization.”

2.3.3 Based on the above submissions, DIAL has considered revenue from Revenue Share Assets for cross

subsidization taking into consideration the following: • Exclusion of revenue from Existing Assets/ Demised Assets • Exclusion of Other Income • Reduction of annual fee payable to AAI pertaining to revenue from Revenue Share Assets.

2.3.4 Based on the above considerations, the Revenue from Revenue Share Assets submitted by DIAL for

True up for the First Control Period can be seen in the table below:

2.3.5 The Authority vide decision No. 2.8.10 of the Tariff Order for the Third Control Period decided not to consider any adjustment in Revenue from Revenue Share Assets towards revenue from Existing Assets and Annual Fee payment to AAI.

2.3.6 In the case of Other Income, the Authority had considered the revenues arising out of sale of Other materials/Scrap- Others, Profit on sale of depreciable assets, management fees, miscellaneous income, Others and Tender Cost recovery as part of revenue for cross subsidization. The interest income received by DIAL (on bank deposits, other deposits and on account of delayed payments) and profit on sale of investments along with Dividend Income have not been considered as part of revenue for cross subsidization.

2.3.7 The detailed rationale for these decisions has been enumerated under the relevant sections in the Tariff

Order for the Third Control Period.

2.4.4 The Authority examined the submissions made by DIAL for true up of Aeronautical Taxes for the First

Control Period on the basis of the following: i. DIAL has considered S Factor as part of the revenue base (based on the Hon’ble TDSAT order dated 21st July 2023) ii. DIAL has not considered Annual Fee as an expense for the purpose of determination of Aeronautical Taxes (based on the Hon’ble Supreme Court order dated 11th July 2022).

2.4.5 As mentioned in para 2.1.3 of this Consultation Paper, the Authority proposes to retain the decisions taken at the time of tariff determination for the Third Control period with regards to treatment of S Factor for computation of Aeronautical Taxes.

2.4.6 As mentioned in para 2.1.4 of this Consultation Paper, the Authority proposes to implement the Hon’ble Supreme Court judgment dated 11th July 2022, and recompute the Aeronautical Taxes based on the regulatory accounts by not treating the Annual Fee pertaining to Aeronautical Revenues as an expense towards True Up of the First Control Period as per the directions contained in the judgement of Hon’ble Supreme Court.

2.4.7 The Authority, as part of the Tariff Order No. 40/2015-16 for the Second Control Period, decided to determine corporate tax pertaining to aeronautical earnings by considering depreciation pertaining to only aeronautical services. The relevant extract from the Tariff Order is mentioned below:

“…the Authority has decided to determine such corporate tax pertaining to aeronautical earnings based on the consideration of actual/projected aeronautical revenue, operating expenses pertaining to aeronautical services, depreciation pertaining to aeronautical assets and interest expense and had considered the applicable tax rate.

The Authority further clarifies that the depreciation, to be considered for such tax calculation, should be the depreciation on account of aeronautical assets only. The Authority is of the view that as

Consultation Paper No: 07/2024-25 Page 42 of 292TRUE UP FOR THE FIRST CONTROL PERIOD Hypothetical Regulatory Base, to be determined in line with SSA, is of hypothetical nature and does not correspond to physical assets in the books of accounts of DIAL, depreciation on such assets should not be considered towards calculation of tax pertaining to aeronautical services.” Accordingly, the Authority proposes to exclude depreciation pertaining to HRAB while considering depreciation pertaining to aeronautical services for computing Aeronautical Taxes for the First Control Period.

2.4.8 Based on the above, the Aeronautical Taxes proposed to be considered by the Authority for true up for

the First Control Period is as follows:

Order for the Third Control Period

3.4.3 The Authority vide decision No. 3.11.12 of the Tariff Order for the Third Control Period decided not to consider any adjustment in revenue from Revenue Share Assets towards revenue from Existing Assets and annual fee payable to AAI.

i. The Authority held the view that as long as non-aeronautical revenues accrue to the Concessionaire from Existing Assets, the same had to be considered for cross subsidization. The Authority also found no merit in excluding such revenue from Existing Assets in the Second Control Period.

ii. The Authority noted that the proposal of DIAL to exclude revenue share of 45.99% pertaining to the Revenue from Revenue Share Assets tantamount to allowing pass-through of the Annual Fee paid with regards to Revenue Share Assets which was against the tariff setting principles enshrined in the OMDA and the SSA. Therefore, the Authority decided not to exclude the Annual Fee from the Revenue from Revenue Share Assets while arriving at the S Factor for the Second Control Period.

3.4.4 The Authority vide decision No. 3.11.13 of the Tariff Order for the Third Control Period decided to consider Other Income, apart from Dividend Income, as part of Revenue from Revenue Share Assets for the Second Control Period.

3.4.5 Based on the above, the revenue from Revenue Share Assets as considered by the Authority for cross subsidization for the Second Control Period in the Tariff Order for the Third Control Period is shown in

the table below:

Authority’s Examination and proposal regarding True Up of Traffic for the Third Control Period as part of the tariff determination exercise for the Fourth Control Period

4.3.4 The Authority analyzed the traffic submission of DIAL as per the MYTP towards true up for the Third

Control Period and has noted the following: a) The trend of actual recovery of Passenger traffic in the Third Control Period has been broadly mirroring the traffic projections made by the Authority at the time of tariff determination for the Third Control Period.

b) The variation in Pax Traffic between the traffic projected by the Authority at the time of tariff determination for the Third Control Period and the actuals as submitted by DIAL is as shown in

the table below:

Table 27: PAX Traffic Variation between the Authority’s Projections and Actuals for the Third Control Period FY ending March 31 (MPPA) 2020 2021 2022 2023 2024 Total Total PAX Traffic Projected by the Authority 67.30 18.39 41.54 67.30 72.59 267.12 Total PAX Traffic as per actuals 67.30 22.58 39.34 65.33 73.67 268.22 Variation (%) – Increase/(Decrease) - 23% -5% -3% 1% c) As can be seen in the table above, except for a considerable variation in FY 2021 on account of Covid-19, the variation in the balance years has been less than 5%.

d) The Traffic has also been independently verified from data available from AAI website and the CA certificate submitted by DIAL with regards to Traffic for the Third Control Period.

Consultation Paper No: 07/2024-25 Page 58 of 292TRUE UP FOR THE THIRD CONTROL PERIOD e) In the case of Cargo Traffic, the variation between the Authority’s Projections at the time of tariff determination for the Third Control Period viz-a-viz the actuals are shown below:

Table 28: Cargo Traffic Variation between the Authority’s Projections and Actuals for the Third Control Period FY ending March 31, (‘000 MT) 2020 2021 2022 2023 2024 Total Cargo Traffic Projected by the Authority 955.86 615.34 823.25 940.86 1,120.07 4,455.37 Cargo Traffic as per actuals 955.86 737.43 924.34 895.92 1,003.31 4,516.86 Variation (%)-Increase/(Decrease) - 20% 12% -5% -10% f) The Cargo Traffic has decreased in FY 2023 and as clarified by DIAL, the same is on account of various reasons including suspension of air traffic to China/ Hong Kong, zero-covid strategy of China resulting in considerable drop in imports, high inflation rate in US/EU resulting in lower transfer of goods carried under air freight etc. Though the actual Cargo Traffic grew ~12% in FY 2024 (896 MMT in FY 2023 to 1,003 MMT in FY 2024), the same was lower (10%) than the Cargo Traffic projected by the Authority at the time of tariff determination for the Third Control Period.

4.3.5 Based on the above submissions along with the justifications, the Authority proposes to consider the Actual Traffic submitted by DIAL as per Table 25 towards True Up for the Third Control Period.

4.4 True up of Capital Expenditure (CAPEX), Depreciation and Regulatory Asset Base (RAB) for the Third Control Period DIAL’s Submissions regarding True up of CAPEX, Depreciation and RAB for the Third Control Period as per MYTP for the Fourth Control Period

4.4.1 DIAL as part of the True Up of Capital Expenditure for the Third Control Period has submitted the

Capex incurred as part of:

A. Phase 3A Expansion capex along with reasons for the escalation in cost B. General Capex for the Third Control Period

4.4.2 Further, DIAL has also submitted the Asset Allocation amongst aeronautical and non-aeronautical as part of the incurred capex along with the corresponding depreciation and the final addition to RAB.

A. Phase 3A Expansion in the Third Control Period

4.4.3 DIAL awarded the EPC contract for the construction of Phase 3A Project to M/s Larson & Toubro (L&T), the successful bidder, through the International Competitive Bidding (ICB) process.

EPC Contract The EPC contract was divided into 5 packages and the details of the packages are as follows: i. Package 1: Expansion of Terminal 1 and associated facilities

4.4.4 Expansion of departure/arrival buildings with a new architectural façade on the city side. Integration with existing Terminal buildings, demolition of some of the existing facilities to facilitate expansion of the terminal footprint and airside asset to meet passenger requirement as per the master plan forecast.

The above expansion will increase the terminal area of Terminal 1 from the current 64,140 sq.m. to 2,06,950 sq.m. and passenger handling capacity from 17 MPPA to 40 MPPA. The features available at

the expanded terminal are as follows: • 13 Entry Gates (26 CISF Positions) • 5 Check-in islands

Original and Revised Project Cost

4.4.9 DIAL in its MYTP for the Third Control Period submitted that the project cost of Phase 3A expansion was Rs. 11,284 Cr including financing allowance of Rs. 1,490 Cr. The break-up of the project cost

submitted by DIAL in MYTP for the Third Control Period is given in the table below:

Table 29: Break-up of Project Cost for Phase 3A submitted by DIAL in the MYTP for the Third Control Period S. No Particulars Amount (Rs. crore) EPC Contract Cost (excluding GST) (A) 8,323

Add: GST @ 18% of Contract Value (B) 1,498

4.4.10 The project cost estimated by DIAL had undergone changes due to delay in the execution of the project attributed to Covid-19 and further impacted by the worldwide supply disruption due to disruptions in Suez Canal and conflict between various Europe/Asian countries, farmers protest in NCR and resultant roadblocks, construction ban by Environment Pollution Control Authority (EPCA) in 2019 to avoid dust pollution, etc. The revised project cost for Phase 3A expansion as submitted by DIAL in the MYTP for

the Fourth Control Period is provided in the table below:

4.4.11 Major items contributing to the change in the project cost are as follows: i. Reduction of GST Input Tax Credit based on actual incurrence

4.4.12 During the initial project cost estimation, based on the components of equipment on which GST input tax credit could have been availed at the prevailing rates, an amount of Rs. 450 Cr was estimated as GST input credit which was duly recorded and shown by DIAL while submitting MYTP for the Third Control

Consultation Paper No: 07/2024-25 Page 61 of 292TRUE UP FOR THE THIRD CONTROL PERIOD Period and the same was adjusted while arriving at the project cost of Rs. 9,794 Cr (i.e. cost of EPC contract net of GST ITC of Rs. 9,371 Cr and cost of enabling works of Rs. 423 Cr). This was based on an estimate that around 30% of the total project cost (Rs. 2,500 Cr) would be plant & equipment that could have been eligible for GST input tax credit.

4.4.13 However, the changes in tax rates, actual cost distribution of the EPC contract to various components i.e. civil and plant & equipment based on actuals resulted in a decrease in the eligible GST input tax credit. Currently, GST input tax credit of Rs. 295 Cr is available as against the earlier estimate of Rs.

450 Cr and the same resulted in additional project cost of Rs. 155 Cr. ii. Increase in Enabling Costs and Soft Costs

4.4.14 Certain additional requirements which were originally not anticipated as part of Phase 3A project cost or wherein additional scope has occurred had to be executed as part of the Project, which includes PIDS for Eastern Cross Taxiway, Self-Baggage Drop (SBD), additional enabling works related to relocation and miscellaneous finishing works in the existing terminal and PMC/other soft costs, which were not in the scope of EPC contractor. The total impact on account of this has been estimated as Rs. 130 Cr.

iii. Interest During Construction period

4.4.15 DIAL initially estimated the IDC for Phase 3A expansion as Rs. 650 Cr, after considering the estimated completion of June 2022. However, actual IDC has increased due to the below-mentioned factors:

• Delay in the execution of the project from June 2022 to March 2024 (around 21 months) on account of Covid-19. • Increase in hard costs of the project. • Decrease in utilization of internal accruals from Rs. 3,800 Cr to Rs. 2,866 Cr.

• Increase in external debt on account of reduction in internal accruals as well as increase in hard costs of the project.

4.4.16 The above resulted in an increase in IDC to Rs. 2,122 Cr as per the submission of DIAL. The interest income earned by DIAL (on surplus debt drawn but unutilized) amounting to Rs. 399 Cr has not been adjusted/ netted-off against IDC based on the Hon’ble TDSAT judgement dated 14th February 2024 in the case of GHIAL.

iv. Relocation of BSF Hangars for execution of Eastern Cross Taxiway works and others

4.4.17 During execution of Phase 3A expansion, it was needed to relocate the BSF Hangars from their existing location for construction of the Eastern Cross Taxiways. It was finally agreed by BSF to relocate the BSF Hangars provided the construction cost of these hangars had to be undertaken by DIAL at their own cost and up to the satisfactory requirements of the BSF.

4.4.18 The total cost on account of the above is Rs. 92 Cr, which has contributed to an increase in cost vis a vis the original submission. v. Claims from EPC Contractor

4.4.19 The EPC contract was originally to be completed by June 2022. Various waves of Covid and other issues including Russia-Ukraine conflict, farmers protest, EPCA construction bans from time to time (particularly the first one in end October 2019 to around mid December 2019), delays in approval by BCAS, delays in issuance of Airport Entry Pass (AEP) for airside works, G-20 event in September, floods in 2023, etc. necessitated the extension of schedule to March 2024.

Consultation Paper No: 07/2024-25 Page 62 of 292TRUE UP FOR THE THIRD CONTROL PERIOD

4.4.20 Due to the delay in the execution of the project, the EPC contractor raised claims worth Rs. 1,221 Cr (including GST). The breakup of this original claims submitted by the EPC Contractor are as shown in

the table below:

Table 31: Break up of the original EPC Claims submitted by the EPC Contractor Particulars (in Rs. Cr) Claims Raised by EPC Contractor Cost Impact due to extended timelines (A) 327.00 Cost Impact due to Price escalation (B) 708.00 Total Cost (Excluding GST) (C= A +B) 1,035.00

Add: GST (@18%) (D) 186.30 Total Cost including GST (E= C+D) 1,221.30

4.4.21 The EPC contractor attributed these claims to additional expenses incurred by them due to Covid-19 protocols, increase in overhead costs during the execution of the project and unprecedented increase in the prices of commodities.

4.4.22 DIAL formed an internal committee to evaluate the additional costs required to be paid to the EPC Contractor considering the impact due to Covid, unprecedented increase in rates of commodities, challenges in logistics and delays that cannot be entirely blamed on the Contractor.

4.4.23 The evaluation by DIAL was considered under the following heads: i. Costs arising due to extended duration of the Contract (supervision, overheads and other time related costs) The internal committee of DIAL deliberated on the overall additional timeline of around 21 months (i.e.

July 2022 to March 2024) considering the major issues as under: o At the time of stoppage of works due to Covid-19 on 25th March 2020, the works were delayed by about 2 months from the original programme primarily due to EPCA restrictions in 2019 which is considered as compliance with applicable laws for which only time extension can be

provided. o The overall Covid-19 extension was granted for 12 months initially and extended to 15 months.

It is highly unjust and inequitable to expect the contractor to bear the cost for the entire 15 months. A Force Majeure period of 4 months due to various waves of Covid-19 between March 20 and May 21 and the delay of 2 months as set out above cannot be compensated for additional costs.

o Out of the balance 9 months, the committee deliberated on a just and equitable distribution of the period that could be compensated. Considering that the Govt. of India (GOI) had recommended that a period of 6 months could be provided to contractors as extension to complete the works without compensation or levy of damages (including 4 months above) and the fact that in a contract of this nature the contractor would have already built-in some inherent delays, the committee took a view that 50% (i.e. 4.5 months) period be considered for extension with cost and balance 50% taken as Force Majeure wherein only time extension could be

provided without additional costs. o BCAS approval delays and stoppage during G-20 contributed to 6 months. These cannot be attributed to the contractor and hence the entire period of 6 months be considered with costs.

Hence, out of overall extended timelines of approx. 21 months, around 10.5 months were considered as just and equitable compensation for evaluation of the costs.

Under the EPC contract, the price schedule has two components, the first component being Preliminaries and General Requirements and the second component being Works. The Preliminaries consider the

Consultation Paper No: 07/2024-25 Page 63 of 292TRUE UP FOR THE THIRD CONTROL PERIOD Contractor’s general obligations and have one-time costs and costs that are time related like supervision, guarantees, running costs, etc.

The Preliminary Schedule is examined and the monthly impact of the recurring costs has been evaluated and the same is set out in the table below. The monthly impact has been evaluated at about Rs. 23 Cr.

The internal committee of DIAL considered it reasonable to recommend a cost of Rs. 20 Cr per month towards the costs that could be related to extension of time. The break-up of the monthly cost

recommended by the internal committee of DIAL is provided below:

Table 32: Monthly Cost Impact due to Extended Timelines as assessed by Internal Committee of DIAL Cost as per BOQ Cost/ Impact due to Extended Timelines (Rs Cr) Impacted (39 months) Month Financial charges such as all permits and clearance, insurance,

ii. Impact due to increase in prices The internal committee of DIAL examined the impact of the increase in price of commodities post Covid-19 and subsequently due to supply disruptions on account of Russia-Ukraine conflict, etc.

As is the methodology followed in major contracts where price escalation is available, the committee evaluated the increase based on WPI. WPI is used as the base when calculating the payment towards escalations in various Govt. contracts and also when unit rates are revised in the Schedule of rates and hence the committee considered that the same could be considered as fair and equitable method of evaluation.

Consultation Paper No: 07/2024-25 Page 64 of 292TRUE UP FOR THE THIRD CONTROL PERIOD Further, only the balance works at the end of the original contract period i.e. June 2022 was considered and the impact of the WPI increase is applied on the same. The computation adopted by the internal

committee of DIAL on the impact due to increase in prices is provided below:

Cr) Value Balance Works as of June 2022 (A) 2,809 75% of the Balance works considered for escalation (B) 2,107 WPI for FY 21-22 (C) 139.40 WPI for FY 22-23 (D) 152.50 Escalation Y-o-Y (E=D/C-1) 9.40% Escalation Factor for period till Mar 2024 (i.e. 21 months/12 months) (F) 1.75 Impact of Price Increase (B*((1+E)^F-1) 358.60 As can be seen from the table above, the impact works out to about Rs. 359 Cr. Further, there was a reduction in scope amounting to Rs. 50 Cr and other minor variations amounting to an increase of Rs. 7 Cr.

Considering all the above, the internal committee of DIAL recommended an amount of Rs. 621 Cr (including GST) as final cost increase of Phase 3A expansion as against the claims amounting to Rs.

1,221 Cr (including GST) submitted by L&T.

Consultation Paper No: 07/2024-25 Page 65 of 292TRUE UP FOR THE THIRD CONTROL PERIOD Asset Allocation Methodology followed by DIAL

4.4.26 DIAL for the purpose of allocation of assets between Aeronautical and Non-Aeronautical Assets for the Third Control Period followed the methodology adopted by the Authority in the Tariff Order for the Third Control Period which was based on the Independent Study commissioned by the Authority on Allocation of Assets at the time of tariff determination for the Third Control Period.

Depreciation

4.4.27 DIAL has computed depreciation for the assets based on the useful life of the assets as per the Companies Act or the concession period whichever is lower. DIAL had also submitted that the same is consistent with the Authority’s Order No. 35/2017-18 on 12th January 2018, which was further amended on 09th April 2018, in the matter of Determination of Useful life of Airport Assets, which was effective from 01st April 2018. The depreciation submitted by DIAL for the Third Control Period in the MYTP for the

Fourth Control Period is as follows:

Deducting the Rs. 393.32 Cr from Rs. 10,897.45 Cr would lead to Rs. 10,504.13 Cr which is the asset addition pertaining to Phase 3A Capex and General Capex.

Authority’s Examination regarding True up of Capital Expenditure, Depreciation and Regulatory Asset Base for the Third Control Period

Background:

4.4.40 The Authority through its independent consultant has proceeded to examine and true up the Capital Expenditure incurred by DIAL in the Third Control Period. The Authority as part of the process has, a) Examined the Phase 3A expansion activity carried out by DIAL with regards to compliance with Master Plan and other statutory requirement.

b) Examined the Cost incurred for Phase 3A expansion including the reasons for the escalation over the original submission and the cost considered by the Authority in the Tariff Order for the Third Control Period.

c) Examined the general capex incurred by DIAL for the Third Control Period against the general capex considered by the Authority at the time of tariff determination for the Third Control Period along with reasons for addition, delay or non-implementation of the major items listed under the general capex.

d) Based on the above, arrived at the Capex that could be considered for True Up for the Third Control Period and the same has been categorized into aeronautical and non-aeronautical additions for True up of RAB for the Third Control Period.

Consultation Paper No: 07/2024-25 Page 69 of 292TRUE UP FOR THE THIRD CONTROL PERIOD Authority’s Examination of Phase 3A Expansion Capex for the Third Control Period Compliance with Master Plan

4.4.41 The Authority noted the relevant provisions under OMDA regarding review of Master plan/ Major

Development Plan as follows:

8.3.5 “..the JVC hereby undertakes to submit the initial Master Plan to the AAI for its information, and to the Ministry of Civil Aviation (“MCA”) for its review and comments before the expiry of six (6) months from the date of execution of this Agreement, which thereafter must be updated and resubmitted to the AAI for its information and to the MCA for its review and comments periodically, every 10 years..”

8.4.1 “The JVC shall develop the Airport in accordance with the Master Plan. The JVC must prepare a Major Development Plan for each major development or any development, which is expected to have a capital cost in excess of Rupees 100,00,00,000/- (Rupees One Hundred Crores Only) and shall ensure that each such major development is undertaken by contractors selected pursuant to a competitive bidding process..”

8.4.2 “The JVC hereby agree to submit each Major Development Plan to AAI for its information and Ministry of Civil Aviation (MCA) for its review and comments. The Major Development Plan must be submitted to the MCA for its review and comments as soon as it is prepared.” The Authority noted that DIAL post consultation with stakeholders and comments from MoCA submitted the final Master Plan 2016 with MoCA on 3rd May 2016 along with amendments and responses. Subsequently, DIAL received inputs/comments from MoCA on 19th May 2016 which were addressed and responded to by DIAL on 27th May 2016.

The Authority also noted the relevant provisions under SSA regarding Master Plan/ Major Development

Plan as follows:

3.8.4 “Within fifteen (15) days of the JVC re-submitting the Major Development Plan in accordance with Clause 3.8.3 hereinabove, GOI shall provide any comments and/or suggested changes that GOI may have vis-à-vis the revised Major Development Plan, to the extent GOI feels that such Major Development Plan is in breach of the provisions set out under the OMDA and/or the parameters set out in Clause 3.8.1 hereinabove are not satisfied. In the event GOI does not, for whatsoever reason, submit any comments and/or suggested changes to the revised Major Development Plan in accordance with the provisions of this Clause 3.8.4, within the prescribed time limit, it shall be deemed that GOI has no comments and/or suggested changes to that revised Major Development Plan and the revised Major Development Plan submitted by the JVC in accordance with Clause 3.8.3 shall be deemed to be the final Major Development Plan, which shall be binding on the JVC and shall regulate the development, operation and management of that particular development (for which the Major Development Plan was prepared) in accordance with the OMDA.”

3.8.5 “In the event GOI provides any comments and/or suggestions to the revised Major Development Plan pursuant to Clause 3.8.4 hereinabove, the JVC shall, within fifteen (15) days of receiving any such comments or suggested changes, submit to GOI the final Major Development Plan, incorporating such comments and/or changes suggested by GOI, that the JVC, in its sole discretion, deems appropriate. The Parties hereby acknowledge and agree that the final Major Development Plan submitted by the JVC shall be binding on the JVC and shall govern the

Consultation Paper No: 07/2024-25 Page 70 of 292TRUE UP FOR THE THIRD CONTROL PERIOD development of that particular development (for which the Major Development Plan was prepared) in accordance with the OMDA.” As per the above clause of SSA, in case, the GoI, for whatsoever reason does not submit any comments and/ or suggest changes to revised Master Plan/ Major Development Plan submitted by JVC within the prescribed time limit, the revised Master Plan/ Major Development Plan shall be deemed to be final.

The Authority noted that since DIAL had not received any further comments from MoCA on the Master Plan after 27th May 2016, the Master Plan submitted to MoCA on 27th May 2016 has been considered as final by DIAL in accordance with relevant clauses of OMDA and SSA.

4.4.42 The Authority noted the submissions made by DIAL and has, through the Independent Consultant (Aviation Expert), examined whether the expansion activities carried out by DIAL is consistent with the submissions made at the time of the Third Control Period and with the Master Plan of IGIA.

4.4.43 The below figure shows the Google Earth image of the layout of the airport and the major facilities before the expansion was undertaken for Phase 3A.

Figure 1: Image of Airport Facilities Pre-implementation of Phase 3A Expansion Project

4.4.44 The OMDA & SSA required DIAL to develop an initial Master Plan (completed in September 2006) and provides an obligation to revise the Master Plan every ten years or at shorter intervals if traffic forecast or other reasons require an earlier assessment. The initial Master Plan was prepared in 2006 by Mott MacDonald. Landrum & Brown (L&B) carried out a review of the Master Plan in 2016.

4.4.45 The facilities proposed in the Master Plan post revision including Redeveloped T1, Eastern Cross Taxiway and Land Side Connectivity improvements are depicted in the Master Plan as per the figure

4.4.47 Based on the above table, it has been observed that certain schemes like Automated People Mover (S.

No 26) and Extension T3 – Infill (S. No 21), are yet to be taken up, of which Extension T3 – infill is proposed to be taken up as part of the expansion capex for the Fourth Control Period.

4.4.48 Overall, with regard to the expansion capex in the Third Control Period, the Authority noted that DIAL proceeded with development activities as per Phase 3A of the Master Plan. The Authority also noted that the scope of EPC contract of Phase 3A Expansion is in conformity with the Master Plan reviewed by L&B.

Passenger Handling Capacity Addition post implementation of Phase 3A Project

4.4.49 The increase in the passenger handling capacity after implementation of Phase 3A expansion across the

three operational terminals of the Airport is provided in the table below:

4.4.50 The increase in the terminal area after implementation of Phase 3A expansion across the three

operational terminals of the Airport is provided in the table below:

Table 44: Terminal area after implementation of Phase 3A Project Area before Phase 3A Addition Area after Phase 3A Terminal (sq.m.) (sq.m.) (sq.m.) Terminal 1 64,140 1,42,810 2,06,950 Terminal 2 54,729 - 54,729 Terminal 3 5,50,193 3,000 5,53,193 Total 6,69,062 1,45,810 8,14,872 Increase % 22%

4.4.51 The Authority noted that post implementation of Phase 3A project, the terminal area has increased by 1,45,810 sq m, an increase of 22% over the pre-existing area while the terminal capacity has increased by 34 MPPA, an increase of over 51% over the pre-existing handling capacity of 66 MPPA. The increase in Pax handling capacity has been necessitated to cater to the fast-growing traffic of IGIA which is the only International Airport currently catering to the capital city of the country. It may be noted that DIAL

Consultation Paper No: 07/2024-25 Page 73 of 292TRUE UP FOR THE THIRD CONTROL PERIOD catered to the traffic of around 74 Mn Pax in FY 2024 which was higher than the earlier capacity of 66 MPPA, justifying the Phase 3A Expansion project.

Bidding Procedure adopted by DIAL

4.4.52 The Authority, based on the information made available by DIAL along with necessary documents, noted that DIAL has awarded the contract for construction of Phase 3A to M/s L&T, the successful bidder through international competitive bidding. It may be noted that the Phase 3A project cost was arrived at based on price discovery through an international tendering process where reputed international contractors with experience in similar projects were shortlisted for tendering.

4.4.53 The project was awarded after following detailed tendering process which involved the following steps: • For pre-qualification of vendor, advertisements were placed in International and National Newspapers mentioned below on 02nd April 2018.

o Economic Times (India All editions) o Times of India (India All editions) o Financial Times (United Kingdom) o Engineering News-Record (Global) • Based on technical and financial requirements listed in the Expression of Interest (EoI), response was received from the following 5 parties:

o Larsen and Toubro, India o Limak Holding, Turkey o ICTAS Insaat, Turkey o China Construction First Group, China o TAV Construction, Turkey/Dubai • Except China Construction First Group, all other parties were qualified. Accordingly, the RFP was shared with the qualifying parties.

• Bids from the three parties were received on 06th December 2018, with one party (Limak) withdrawing from the tender. • Technical and commercial evaluation committee was formed by DIAL for carrying out detailed evaluation of the bids.

• L&T emerged as the lowest bidder (L1) by submitting a bid of Rs. 10,510 Cr (including GST) which was further negotiated by DIAL to Rs. 9,821 Cr (including GST). • The process of tendering, evaluation and negotiations by DIAL resulted in the discovery of price lower than the initially tendered EPC cost for Phase 3A works. The final price was arrived at after negotiations with the lowest bidder, L&T, which quoted 6% lower than its initial bid (i.e. Rs. 9,821 Cr against the original quote of Rs. 10,510 Cr).

• The final price provided by L2 bidder was around 2.3% higher than L&T’s bid and that provided by L3 bidder was around 11.3% higher than L&T’s bid.

4.4.54 From the above submissions by DIAL, the Authority is of the view that the procedure adopted for the award of contract to L&T appears to be transparent and efficient.

Comparison of Project Cost

4.4.55 A comparison of revised project cost submitted by DIAL for Phase 3A Expansion Capex in the MYTP for the Fourth Control Period towards true up for the Third Control Period viz-a-viz the cost approved by the Authority at the time of tariff determination for the Third Control Period along with initial

4.4.56 It may be noted that the Authority in the Tariff Order for the Third Control Period approved project hard cost of Rs. 9,126 Cr (after considering inflation and GST impact of Rs. 503 Cr and Rs. 655 Cr respectively over the cost assessed by KITCO i.e. Rs. 7,969 Cr which was based on independent study by KITCO and not based on tender award cost as submitted by DIAL). The Authority at the time of tariff determination for the Third Control Period carried out an independent study through KITCO on the capex proposed for the Third Control Period much before the award of the tender by DIAL. The study on the capex was completed well before the award of tender by DIAL. As there was a time gap, the Authority relied on estimated cost by adding the inflation cost and GST to arrive at the cost considered for tariff determination for the Third Control Period.

4.4.57 The Authority has also indicated that they shall consider any further escalation if submitted with reasons deemed justifiable at the time of tariff determination for the Fourth Control Period.

4.4.58 At the time of independent study conducted by KITCO, the values for various packages were worked out based on Master Plan/preliminary design & block cost estimates. DIAL got the Major Development Plan formulated through AECOM & NACO (2017) based on the revised Master Plan carried out by L&B (2016). The Major Development Plan was made available to the prospective EPC bidders at the time of inviting tenders. The prospective EPC bidders were supplied with development plan which enabled them to arrive at their estimates for the value of works covered under various packages after carrying out front end engineering design before quoting for the contract.

4.4.59 There are variances in the cost estimate assessed as per the Independent Study and the estimated cost prepared by DIAL and the final negotiated bid amount of the EPC Contractor. DIAL submitted that certain unique and specific factors of IGIA, though intimated to KITCO by way of verbal/written submissions, have not been deliberated by KITCO to the extent required and hence not factored in their cost estimation. Some of the factors affecting the cost, are a result of unique conditions associated with IGIA which is the busiest airport in the country with high intensity operations of approx. 1,300 ATMs per day, unlike airports like Hyderabad or Kolkata which experience less than half the traffic of IGIA.

Due to these high intensity operations coupled with low visibility periods, VVIP visits, compliance with

Consultation Paper No: 07/2024-25 Page 75 of 292TRUE UP FOR THE THIRD CONTROL PERIOD NGT instructions, vehicular movement of construction material in airside, etc., the EPC contractor has to account for multiple operational challenges as well as time factor while undertaking the works.

Cost Variations between the Packages

4.4.60 The Authority noted that there are significant variations in the completed cost of Packages 3 and 4 and reviewed the reasons for the variation in general and with respect to Packages 3 and 4 in particular to ascertain the contributing factors for such variations.

4.4.61 The cost break-up submitted by DIAL in MYTP for the Third Control Period was tentative based on final EPC bid value wherein the allocation among various packages was based on preliminary estimation. However, it was informed by DIAL that as the work progressed, EPC Contractor came out with various changes among packages keeping the total EPC value same. A major re-distribution took place in Package 3 & 4 on account of overlapping works. Further, it was pointed out by DIAL that the allocation among various packages was more of a payment mechanism used by EPC Contractor to reflect various milestones in the project for raising invoices. Hence, DIAL clarified that it may not be appropriate to consider the same as final cost towards development of a particular asset, as EPC Contractor would have relied on its economies of scale in some of the cases, while for others it would have used specialized contractors for executing the work based on their ability to negotiate. Therefore, DIAL submitted that it would not be prudent to consider favorable costing for one asset under the package while ignoring higher rates in the case of other packages. As per DIAL, the inter-se package arrangements were prerogative of EPC contractor whereas the final EPC cost had no significant variance.

4.4.62 DIAL informed that there have been some reallocations of work components and general requirements, within the packages, especially so, in Package 2 where certain elements have been moved from Package 2 to Package 3 & 4 resulting in an increase in completion costs of Package 3 & 4 with a reduction in completion cost of Package 2. Thus, revision of costs under different packages can be mainly attributed to the following factors which were not envisaged at the time of submission of MYTP for the Third

Control Period: • Adjustment between Package 2 and Package 4: Cost of taxiways to the north and south and contiguous with Eastern Cross Taxiway (ECT) which were originally considered under the overall airside costs in the MYTP for the Third Control Period have been transferred under ECT (Package

4). Further, the drainage work required for the ECT (which was also considered under the Airside Package 2 in the submission) has been moved to Package 4. This explains the increase in the overall value of Package 4.

• Adjustment in value of Apron works: The Head of Stand (HOS) road of about 50,000 sq.m. considered under Aprons in the submission has been shifted to Landside (Package 3) which substantiates the reduction in the cost under the head ‘Aprons’.

• Adjustment in value of landside works: The cost of landside works considering the ground conditions, utility diversions, working in public areas, etc. has increased and the EPC contractor has made minor adjustments amongst the packages to account for this increase. Further, HOS road costs have been included under this head.

4.4.63 Considering the above, the Authority finds it appropriate to make a comparison of the total cost of all the packages together, rather than comparing them on a ‘package to package’ basis. This is because the package-wise cost does not truly represent the actual cost of the facilities covered under each of the packages. Package-wise cost was bifurcated for the purpose of deciding the milestone payments with reference to which payments are to be released to the EPC contractor.

Consultation Paper No: 07/2024-25 Page 76 of 292TRUE UP FOR THE THIRD CONTROL PERIOD

4.4.64 Accordingly, the Authority through its Independent Consultant/Aviation Expert proposes to consider the overall cost of the EPC Contract for assessment of reasonableness of the capex instead of cost of each of the packages under the EPC Contract as there has not been any major variation in the overall cost.

Cost Escalation and Other Variations

4.4.65 The cost of Phase 3A Expansion (EPC costs and Other Enabling costs) submitted in the MYTP for the Fourth Control Period vis a vis the submission for the Third Control Period has a variation of ~Rs. 285 Cr (i.e. ~3% of the total cost). As per DIAL, the difference of Rs. 285 Cr is attributable to certain un- controllable factors related to reduction in GST ITC by Rs. 155 Cr and increase in enabling costs by ~Rs. 130 Cr. In addition to this, there has been additional costs pertaining to Relocation of BSF Hangars and EPC claims. The break-up of the final project cost submitted by DIAL is provided in the table below:

Table 46: Break-up of Final Project Cost for Phase 3A submitted by DIAL DIAL’s DIAL’s Variation Particulars (Rs Cr) Submission in Submission in (+/-) MYTP for 3rd CP MYTP for 4th CP EPC Cost (A) 8,323.00 8,323.00 - GST @ 18% (B) 1,498.00 1,498.00 - GST Input Tax Credit (ITC) (C) 450.00 295.00 (155.00) EPC Contract Cost (D=A+B-C) 9,371.00 9,526.00 155.00 Other Enabling Costs (PMC, insurance etc.) (E) 423.00 552.50 129.50 Relocation of BSF Hangars (F) - 91.50 91.50 EPC Claims (G) - 621.00 621.00 Total Hard Cost (H=D+E+F+G) 9,794.00 10,791.00 997.00 Financing Allowance/ IDC (as applicable) (I) 1,490.00 2,121.54 631.54 Total Project Cost (H+I) 11,284.00 12,912.54 1,628.54

4.4.66 Based on the above submission, the Authority through its independent consultant / Aviation Expert examined DIAL’s submissions regarding project cost of Phase 3A Expansion Capex and the

observations of the Authority are as follows: i. Cost of EPC Contract

4.4.67 The Authority is of the view that the procedure adopted for award of contract to L&T appears to be

transparent and efficient on account of the following: • Scope of the EPC contract is in conformity with the Master Plan reviewed by L&B. • The contractor was selected based on the International Competitive Bidding (ICB).

• The final price was arrived at after negotiations with the lowest bidder, L&T. The price quoted by L2 and L3 bidder were around 2.3% and 11.3% higher than L&T’s bid respectively. • The decision to award the EPC contract to L&T was also approved by the Board of DIAL in 2019.

4.4.68 Considering the above, the Authority proposes to consider the value of the EPC contract (excluding GST) i.e. Rs. 8,323 Cr as the same was approved by the Board of DIAL which constituted members from AAI and MOCA as well.

ii. GST (Pre and Post Tender)

4.4.69 The Authority noted that the GST on the EPC contract worked out to Rs. 1,498 Cr at an applicable rate of 18%. DIAL at the time of submission of MYTP for the Third Control Period estimated GST Input Tax Credit (ITC) of Rs. 450 Cr which was estimated as an approximation by applying 18% GST on value of Plant & Equipment (P&E) under the EPC contract. It may be noted that the value of P&E under

Consultation Paper No: 07/2024-25 Page 77 of 292TRUE UP FOR THE THIRD CONTROL PERIOD the EPC contract was estimated as 30% of the EPC contract value of Rs. 8,323 Cr i.e. Rs. 2,500 Cr.

Accordingly, 18% of the value of P&E of Rs. 2,500 Cr worked out to Rs. 450 Cr.

4.4.70 Considering the GST ITC of Rs. 450 Cr, the EPC cost including GST (net of ITC) was estimated as Rs.

9,371 Cr (i.e. Rs. 8,323 Cr plus applicable GST of Rs. 1,498 Cr less GST ITC of Rs. 450 Cr) as per DIAL’s original submission at the time of tariff determination for the Third Control Period.

4.4.71 However, variations in actual distribution of the value of EPC contract to various components viz. civil and P&E based on actuals resulted in lower GST ITC than estimated at the time of MYTP for the Third Control Period.

4.4.72 DIAL in the MYTP for the Fourth Control Period submitted that as against an initial estimate of P&E of Rs. 2,500 Cr, actual P&E pertaining to Phase 3A Expansion Capex that was eligible for GST ITC worked out to Rs. 1,620 Cr. Correspondingly, actual GST ITC is estimated to be around Rs. 295 Cr viz- a-viz Rs. 450 Cr estimated earlier.

4.4.73 DIAL has submitted CA certificate towards eligible GST ITC for the bills raised by Contractor till 31st March 2024, which amounts to Rs. 201.87 Cr and the same has been verified by the Authority through its independent consultant.

4.4.74 Further, Equipment availed on Lease Finance is proposed to be excluded from the Project Cost capitalized and hence the corresponding GST of Rs. 72 Cr (i.e. 18% on cost of equipment of Rs. 400 Cr) is also proposed to be excluded from the Project Cost capitalized. The cost incurred on account of Lease Finance has been allowed as an Aeronautical operation and maintenance expense subject to the same being the efficient cost.

4.4.75 Of balance bills of Rs. 525 Cr pending as on 31st March 2024, DIAL estimates that bills amounting to Rs. 93.06 Cr would be eligible for availing GST ITC while the balance bills would not be eligible for availing GST ITC. The said workings are summarized below for reference:

Table 47: GST Split Up for the EPC Cost of Phase 3A works Particulars (Rs. Cr) EPC Cost GST GST ITC Bills pertaining to Civil Works (A) 6,271.14 1,128.81 - Bills pertaining to Plant & Machinery (B) 1,526.94 273.87 273.87 Bills raised on DIAL 1,126.94 201.87 201.87* Equipment through lease finance 400.00 72.00 72.00 Sub Total (C=A+B) 7,798.08 1,402.68 273.87 Balance bills on which ITC is eligible (D) 93.06 20.48 20.48 Balance bills on which ITC is not eligible (E) 431.86 74.98 - Grand Total (C+D+E) 8,323.00 1,498.14 294.35 *CA certificate has been submitted by DIAL

4.4.76 The Authority, through its independent consultant, after examining the submissions of DIAL including the CA certificates, proposes to consider GST ITC of Rs. 295 Cr for adjustment against the applicable GST on the Project Cost as submitted to the Authority.

4.4.77 The Authority also proposes to true up the GST ITC based on actuals after considering any additional ITC eligibility that could accrue based on revised regulatory and legal directions with regards to GST ITC claiming guidelines of GOI.

Consultation Paper No: 07/2024-25 Page 78 of 292TRUE UP FOR THE THIRD CONTROL PERIOD

4.4.78 Considering the above, the cost of EPC contract of Phase 3A Expansion Capex after adjusting GST ITC proposed to be considered by the Authority is Rs. 9,526 Cr as detailed below:

Table 48: EPC Cost proposed to be considered by the Authority for the Third Control Period DIAL’s Submission in Proposed to be considered Particulars (Rs. Cr) MYTP for 4th CP by the Authority EPC Cost 8,323.00 8,323.00

4.4.79 DIAL in the MYTP for the Third Control Period submitted cost of Rs. 423 Cr towards miscellaneous and enabling works forming part of Phase 3A Expansion Capex which include preliminary works, design, development and supervision works, consultancy charges and other soft costs. DIAL in the MYTP for the Fourth Control Period submitted that the actual cost incurred towards miscellaneous and enabling works increased from the originally estimated Rs. 423 Cr to Rs. 552.50 Cr.

4.4.80 The Authority noted that DIAL had not provided the break-up of Rs. 423 Cr of miscellaneous and enabling works at the time of tariff determination for the Third Control Period. The Authority approved the capex for Phase 3A Expansion based on the study by KITCO independent of the capex submitted by DIAL including for enabling works.

4.4.81 KITCO estimated project cost of Rs. 7,970 Cr which was based on Master Plan, comprising of hard cost of Rs. 7,284 Cr and enabling works/contingencies/ preliminaries of Rs. 686 Cr. The Authority approved the capex for Phase 3A Expansion after considering addition of Rs. 1,158 Cr (impact due to inflation and GST) on the cost estimated by KITCO. Accordingly, the Authority allowed capex of Rs. 9,126 Cr (excluding IDC of Rs. 427 Cr) based on the recommendation of the independent consultant.

4.4.82 The Authority as part of the current tariff determination exercise sought item-wise break-up of originally estimated cost of Rs. 423 Cr (since break-up was not provided at the time of tariff determination for the Third Control Period) along with mapping of the same with the actually incurred cost. The break-up of cost towards miscellaneous and enabling works along with mapping as provided by DIAL is tabulated

4.4.83 The Authority noted that the cost towards miscellaneous and enabling works increased from Rs. 423 Cr to Rs. 552.50 Cr i.e. an increase of Rs. 129.50 Cr from the original submission of DIAL.

4.4.84 DIAL stated that certain additional requirements which were not anticipated originally as part of total project cost or where additional scope had to be executed as part of the project such as Perimeter Intrusion Detection System (PIDS) for Eastern cross taxiway, Self-Baggage Drop (SBD), additional enabling works relating to relocation and miscellaneous finishing works in the existing terminal and linked soft costs. These items form part of Other Miscellaneous Works and Soft Costs in the table above.

4.4.85 The major reasons for increase in Enabling and Miscellaneous costs as submitted by DIAL are tabulated

4.4.88 Relocation of BSF Hangar became necessary for making way for construction of Apron for T1 and Eastern Cross Taxiway as part of the Development Plan and the Master Plan. The Authority reviewed the procedure adopted for awarding this work.

4.4.89 DIAL explained that tenders were not called to award this work since this area is contiguous to the area where L&T is already carrying out its expansion works. Therefore, it became imperative to continue with the same construction agency to avoid coordination problems which might have arisen if the work was awarded to a different contractor. DIAL confirmed that rates of items under this work were negotiated based on the rates in the EPC contract under execution with L&T.

4.4.90 DIAL explained the Authority during the site visit that the work awarded was unavoidable as these were located on the expanded Apron of T1 and had to be relocated to avoid any obstruction to the Eastern Cross Taxiway as well.

4.4.91 The Google Earth image showing relocation of BSF Hangar is given below:

Consultation Paper No: 07/2024-25 Page 85 of 292TRUE UP FOR THE THIRD CONTROL PERIOD Figure 3 : Relocation of BSF Hangar

4.4.92 The Authority also examined the cost of Rs. 91.50 Cr towards relocation of BSF Hangar as submitted by DIAL comprising of Rs. 83 Cr pertaining to EPC contract awarded to L&T, cost of Rs. 5.13 Cr pertaining to contract awarded for earthwork, site grading and levelling works and other enabling costs of Rs. 3.37 Cr primarily comprising of salaries and other consultancy charges. The Authority, through its independent consultant, noted that the cost incurred is found to be reasonable and the same is net of salvage value of the existing assets.

4.4.93 After examination of the costs submitted by DIAL, the Authority, based on input from Independent Consultant/ Aviation Expert, proposes to consider the cost of Rs. 91.50 Cr pertaining to relocation of BSF Hangar.

v. Claims from EPC Contractor

4.4.94 The Authority has already taken into cognizance the delay in completion of the Phase 3A Expansion Capex and revised the capex phasing and extended completion timeline of 31st March 2024 at the time of tariff determination for the Third Control Period.

4.4.95 The Authority noted that the EPC contractor raised claims worth Rs. 1,221 Cr including GST of Rs. 186 Cr. The items under which this claim was made are provided in Table 31. The EPC contractor attributed these claims to additional expenses incurred by them due to Covid-19 protocols, increase in overhead costs during the execution of the project and unprecedented increase in the prices of commodities.

4.4.96 The Authority noted that the internal committee formed by DIAL for evaluation of claims was represented by members of all teams involved in/ related to Phase 3A Expansion Capex i.e. Project (including PMC), Procurement, Contracts and estimations team. The designations of the members of the

internal committee are as follows: • Chief Development Officer (CDO) • Head – Planning • Head – Estimation • GM – Contracts (Phase 3A) • Head – Project Procurement • Head – Project Finance & Accounts • PMC representative

Consultation Paper No: 07/2024-25 Page 86 of 292TRUE UP FOR THE THIRD CONTROL PERIOD Additional Costs due to extended duration on account of Covid-19 and other delays

4.4.97 The Authority noted that the total claims raised by the EPC Contractor on account of the extended duration of the contract was Rs. 327 Cr excluding GST.

4.4.98 The Authority through its independent consultant/ aviation expert examined the submissions of DIAL with respect to the computation of costs arising due to extended duration of the EPC contract.

4.4.99 The Authority refers to the directions from Government of India regarding enforceability of contractual provisions during Covid-19 vide Office Memorandum from Department of Expenditure, Ministry of Finance dated 19th February 2020 and 13th May 2020.

As per the Office Memorandum dated 19th February 2020, it was clarified that disruptions of supply chains due to spread of Covid-19 will be covered under Force Majeure Clause (FMC) which could be invoked wherever considered appropriate following the due procedure as stated in para 9.7.7 of the Manual on Procurement of Goods.

Subsequently, as per the Office Memorandum dated 13th May 2020, the parties to the contract are allowed flexibility to invoke FMC following prescribed due procedure. It recognizes that it may not be possible for the parties to the contract to fulfil contractual obligations in respect of PPP concession contracts. Therefore, after fulfilling due procedure and wherever applicable, parties to the contract may invoke FMC for all construction contracts and in such event, date for completion of contractual obligations which had to be completed on or after February 20, 2020 shall stand extended for a period not less than 3 months and not more than 6 months without imposition of any cost or penalty on the contractor.

As mentioned above, Government of India directed that the parties may invoke FMC clause of the construction contract and allowed time extension for not more than 6 months without imposition of any cost/penalty on the contractor.

4.4.100 The Authority after examination of the submission of DIAL, through its independent consultant/ Aviation Expert proposes to consider time extension of 6 months as directed in the Office Memorandum issued by the Government of India with costs.

4.4.101 With regard to delays in receipt of approvals from BCAS and other security agencies as claimed by DIAL, the Authority sought detailed clarifications on the timelines pertaining to the delay. Towards this,

the responses of DIAL are as follows:

4.4.101.1 DIAL considered time period of 6 months towards costs related to time extension on account of delays due to NGT ban on construction activities and receipt of approvals from BCAS & other security agencies.

Table 52: Delay in receipt of approval from BCAS Reasons for Delay Time period Delays due to NGT ban on Construction activities 4 months Delays in receipt of approvals from security agencies 8 months i. Delays due to NGT ban on Construction activities: Construction ban was imposed by Environmental Pollution (Prevention & Control) Authority (EPCA), Hon’ble Supreme Court & other bodies during months of October to December every year. The ban along with implementation of Graded Response Action Plan (GRAP) by Government resulted in closing of Diesel Generator (DG), Hot Mix Plant (HMP) & Stone Crusher and associated consequences. The total delay on account of this is estimated as 111 days i.e. nearly 4 months.

Delay in receipt of approvals from DGCA and BCAS: General delays in approval from the security agencies including BCAS in approval of Terminal related works led to enormous delays in putting completed works to use and consequently delaying sequential works. The delay has affected the Terminal works which are sequential in nature. The total impact is assessed as 8 months.

4.4.102 The Authority, after examination though its Independent Consultant/ Aviation Expert of the above found the justification of DIAL as reasonable considering that the above-mentioned factors are not under the control of DIAL. Accordingly, the Authority proposes to consider the delay of 6 months attributed to

Consultation Paper No: 07/2024-25 Page 88 of 292TRUE UP FOR THE THIRD CONTROL PERIOD NGT ban on construction activities and delays in receipt of approvals from BCAS and other security agencies as submitted by DIAL.

4.4.103 Accordingly, the total time period for extension with costs (Covid-19 related delays as well as delays from security agencies) works out to 12 months. Hence, the Authority proposes to consider the time period for extension with costs as 10.5 months as evaluated by DIAL as the same is found reasonable and within the time period as assessed by the Authority.

4.4.104 The Authority is also of the view that the computation of monthly costs of Rs. 20 Cr based on the Preliminary Schedule of the Contract as reasonable. The Authority also highlights the fact that the total impact as per DIAL’s evaluation (Rs. 210 Cr) is considerably lower (~36%) than the claims raised by the EPC Contractor (Rs. 327 Cr).

4.4.105 Therefore, the Authority proposes to consider additional costs of Rs. 210 crore (10.5 months x Rs. 20 Cr) on account of extension in time for execution of the contract as submitted by DIAL, as the same has been approved by the Board of DIAL which has representation from AAI as well as MOCA.

Additional Costs due to Price Increase

4.4.106 The Authority noted that the total claims raised by the EPC Contractor on account of price increase was Rs. 708 Cr excluding GST.

4.4.107 The Authority notes that the EPC contract is a fixed time lumpsum contract with no provisions for cost increase as can be seen in the relevant clause of Section 8 (Sufficiency of the Contract Sum) of the EPC

contract as below: “The Contractor shall be deemed to have satisfied itself before entering into the contract as to the correctness and sufficiency of the Contract Sum and of the rates and prices stated in the Price Breakdown and the Schedule of Prices, all of which shall, except as otherwise provided for in the Contract, cover all its obligations under and in relation to the contract and all matters and things necessary for the proper execution of the works, whether the same is expressly provided for in the contract or is to be reasonably inferred there from or is necessarily incidental thereto. The Contract Sum is a lump sum fixed price and will not be adjusted save as expressly provided in the Contract, and includes any and all direct, indirect and ancillary charges and costs of whatsoever nature……”

4.4.108 The Authority also noted the clause with regards to time escalation and the compensation in claims for the delay/extension in time period in the EPC Contract as below: “It shall be a condition precedent to any extension of time by the Employer under any provision of the Contract, that in respect of each and every incident, circumstances or event identified in the notice given in accordance with Clause 26.1 [Contractor’s notice of event likely to cause delay], the Contractor shall, as soon as possible after such notice or such longer period as the Employer’s Representative may in its absolute discretion determine, notify the Employer’s Representative, in writing, of any factors and relevant Contract provision which it considers may entitle it to claim an extension of time together with a statement, by reference to the Programme where appropriate, providing:

26.2.1 full and detailed particulars of the expected effects of delay

26.2.2 the reasons why the delay has occurred or is likely to have occurred

26.2.3 an explanation of any measure that the Contractor has adopted or proposes to adopt to avoid or reduce or mitigate the consequences of the delay or impediment

26.2.4 details of which of the Delay Events (if any) has caused the delay or impediment;

Consultation Paper No: 07/2024-25 Page 89 of 292TRUE UP FOR THE THIRD CONTROL PERIOD

26.2.5 details of any adverse effect on the ability of the Contractor to meet the Employer’s Requirements and any other requirements under the Contract

26.2.6 an estimate of the extent of the expected delay in Completion beyond the relevant Time for Completion and any anticipated additional costs if any, as allowed under the contract, resulting from the delay

26.2.7 details of the documents the Contractor proposes to prepare and maintain to support any claim for an extension of time which must include a critical path network and other documents as required by the Employer’s representative in order to demonstrate entitlement

26.2.8 details of the measure which it has discussed and agreed with its Subcontractors to facilitate the reprogramming of the performance of their services as a consequence of the delay

26.2.9 further substantiation of any particulars and estimate aforesaid as the Employer’s Representative may reasonably request

26.2.10 reasons as to why in the Contractor’s opinion, the Contractor is entitled to any extension of time or compensation payment pursuant to any Project Document by reason of any delay and

26.2.11 confirmation that it is a notice pursuant to this Clause 26.2 [Reason for delay and extension of time]”

4.4.109 The Authority hence proposes to examine the submission of DIAL with regard to assessment of cost increase due to increase in prices of commodities as the same is attributed to Covid-19 pandemic and other external factors like Russia-Ukraine conflict.

4.4.110 DIAL submitted that majority of the works pertaining to Phase 3A were completed only by March 2024 as against scheduled timeline of June 2022 i.e. a delay of 21 months. The Authority also proposes to consider delay of 21 months for computing cost increase due to increase in commodity prices as per DIAL’s submission.

4.4.111 The Authority through its Independent Consultant/ Aviation Expert noted that DIAL in its evaluation of price increase has applied WPI escalation only on 75% of the value of the pending works as of June 2022 which is considered reasonable. Further, the Authority also found merits in the justification

provided by DIAL with regards to the claim by the EPC Contractor considering that the WPI (All Commodities) increased considerably during the 15-month period between March 2021 and June 2022.

4.4.112 The Authority has also taken note of DIAL’s evaluation of impact of price increase wherein total WPI impact of 17.02% is considered by applying multiplication/escalation factor of 1.75 (21 months/12 months) on the WPI increase of 9.4% pertaining to 12-month period between FY 2022 and FY 2023 and found the same as reasonable. The Authority also highlights the fact that the total impact as per DIAL’s evaluation (Rs. 358.60 Cr) is almost half of the claims raised by the EPC Contractor (Rs. 708 Cr).

4.4.113 Therefore, the Authority through its Independent Consultant/ Aviation Expert proposes to consider the total impact of Rs. 358.60 Cr on account of price increase as evaluated by DIAL.

Total Impact

4.4.114 The Authority while considering the final impact on account of delay in execution of works and price

increase takes cognizance of the following: • After negotiations with DIAL, the EPC Contractor vide letter dated 24th September 2024 agreed for overall final settlement of Rs. 621 Cr including GST towards various claims/variations in the Project.

Consultation Paper No: 07/2024-25 Page 90 of 292TRUE UP FOR THE THIRD CONTROL PERIOD • Evaluation of claims by the internal committee formed by DIAL has been approved by the Board of Directors of DIAL on 31st January 2024 which also comprise nominee directors from AAI and MoCA.

4.4.115 The Authority through its Independent Consultant/ Aviation Expert is of the view that the additional costs due to time overrun and cost overrun seems to be justified and reasonable on account of the above- mentioned reasons. However, the GST portion of the same shall not be considered as part of the current tariff determination exercise in the absence of necessary documentation to support the same. This amount shall be trued up based on actual incurrence at the time of tariff determination for the Fifth Control Period post necessary deductions towards Input Tax Credit if any claimed by DIAL. The Authority understands that while GST is a statutory obligation, the same could be allowed as part of true up based on actual incurrence consistent with the decisions taken by the Authority with regards to Other Statutory obligations such as Property taxes, etc.

4.4.116 It may be noted that the scope of EPC Contractor includes works related to Runway 10/28 and other minor areas which were de-scoped as fronts could not be provided to the Contractor on time for executing these works. The cost of the same has been evaluated as Rs. 50 Cr by DIAL. Further, there were other variations in the execution of the Contract with a total impact of Rs. 7 Cr which includes:

• Increase in nos. of security checkpoints/Nakas at Terminal-1 • Reimbursement of additional fees charged by architects • Revision of Alignment of Left Carriageway of Parallel Access Road between Automated Mail Sorting Centre and New Custom House

4.4.117 The Authority after examination by the Independent Consultant/ Aviation Expert of the above decided to consider the reduction in scope and variation as submitted by DIAL.

4.4.118 The Authority through its independent consultant and aviation expert computed the total impact on account of delay in execution of the contract and price increase after adjusting for reduction in scope

and other variations as follows:

Table 55: EPC claims proposed to be considered by the Authority for the Third Control Period Particulars (Rs. Cr) Claims Raised by Claims Approved Proposed to be EPC Contractor by Board of DIAL considered by the Authority Cost impact due to extended timelines (A) 327.00 210.00 210.00 Cost impact due to price escalation (B) 708.00 358.60 358.60 Reduction in Scope (C) 50.00 50.00 Other Variations (D) 7.00 7.00 Sub Total (E=A+B-C+D) 1,035.00 525.60 525.60

Add: GST @ 18% (F) 186.30 94.60 - Total including GST (G=E+F) 1,221.30 620.20 525.60

4.4.119 The Authority hence proposes to consider an amount of Rs. 525.60 Cr towards various claims from the EPC Contractor without considering the impact of GST. The Authority proposes not to consider the impact of GST at present and would true up the GST at actuals (net of Input Tax Credit, if any claimed by DIAL in future) at the time of tariff determination for the Fifth Control Period.

Consultation Paper No: 07/2024-25 Page 91 of 292TRUE UP FOR THE THIRD CONTROL PERIOD vi. Interest During Construction Period

4.4.120 The means of finance considered by the Authority in the Tariff Order for the Third Control Period and revised and actual means of finance for Phase 3A Expansion as submitted by DIAL as per MYTP for

the Fourth Control Period are as follows:

Table 56: Means of Finance submitted by DIAL for true up for the Third Control Period in MYTP for the Fourth Control Period vs Means of Finance considered by the Authority Particulars (Rs.

4.4.121 The details of external debt availed by DIAL for Phase 3A Expansion are provided in the table below:

Table 57: Debt availed by DIAL for Phase 3A Expansion in the Third Control Period Net Amount Utilized Towards Phase 3A Particulars Date of Drawdown Expansion (Rs. Cr) USD 350 Mn 2,424 07-Jun-19 USD 150 Mn 1,076 26-Feb-20 NCD INR 3,257 crore 1,350 30-Mar-21 NCD INR 1,000 crore 1,000 22-Jun-22 NCD INR 1,200 crore 1,200 13-Apr-23 NCD INR 800 crore 800 22-Mar-24 Total 7,850

4.4.122 The Authority noted that since the debt instruments are in the form of bonds/ debentures, DIAL had drawn down some of the facility upfront before the necessary expenses were proposed to be settled.

This had resulted in additional interest on the amount drawn which could not be considered as an Efficient Interest Cost. The IDC component submitted by DIAL is Rs. 2,122 Cr. The interest income earned by DIAL (on surplus debt drawn but unutilized) amounting to Rs. 399 Cr has not been adjusted by DIAL to arrive at the net IDC based on the Hon’ble TDSAT judgement dated 14th February 2024 in the case of GHIAL.

4.4.123 As mentioned in para 4.2.3 of this Consultation Paper, the Authority proposes to retain the decisions taken at the time of tariff determination for the Third Control period and proposes that only the efficient cost of interest can be allowed for arriving at RAB.

4.4.124 In order to compute the efficient interest cost, the Authority proposes to notionally reassess IDC based on the actual payment schedule submitted by DIAL with respect to Phase 3A Expansion Capex.

i. The Authority noted that notional assessment of IDC is also required considering that DIAL has actually utilized debt of only Rs. 6,781 Cr as on 31st March 2024 as against proposed debt of Rs.

7,850 Cr. However, DIAL has almost capitalized entire cost of Phase 3A Expansion except assets to the extent of Rs. 201.23 Cr under Package 1 of EPC contract (pertaining to Airport village) (i.e. Rs. 62.21 Cr recognized as CWIP as on 31st March 2024 while works to the extent of Rs. 139.02 Cr was yet to be executed as on 31st March 2024). The Airport village (under package 1 of EPC contract) is a landside facility that provides interconnectivity between the terminal building and the landside transportation network. It is designed to help passengers and

Consultation Paper No: 07/2024-25 Page 92 of 292TRUE UP FOR THE THIRD CONTROL PERIOD visitors make sense of orientation, enhancing their experience of the Airport in terms of improved comfort, security and convenience.

ii. As mentioned earlier, though DIAL capitalized ~98.33% of the capex pertaining to Phase 3A as on 31st March 2024, it has utilized only 86.38% of the proposed debt as on 31st March 2024 leaving debt of Rs. 1,069 Cr unutilized as on 31st March 2024.

iii. For the purpose of notional assessment of IDC, it is considered that hard cost of the capex would be funded at a debt/equity ratio proportionate to the D:E ratio of the overall capex excluding IDC while the entire IDC is assumed to be funded out of debt.

iv. The Authority also submits that IDC is computed at the Efficient Cost of Debt proposed to be considered by the Authority for the Third Control Period i.e. 10.37% on the average debt arrived at every year based on notional assessment.

4.4.125 The assessment of IDC for Phase 3A Expansion Capex proposed to be considered by the Authority is as

follows:

Table 58: IDC proposed to be considered by the Authority for the Third Control Period FY Ending March 31, (Rs.

Note: Total debt utilized by DIAL as on March 31, 2024 was Rs. 6,781 Cr. Addition of debt (J) is considered based on a proportionate Debt drawl corresponding to the actual debt utilized.

4.4.126 Based on the above assessment, the Authority proposes to consider IDC of Rs. 1,396.77 Cr towards Phase 3A Expansion Capex.

4.4.127 The Authority vide its decision no 4.6.7 in the Tariff Order for the Third Control Period decided to consider a provision for adjustment towards RAB to the extent of 1% of the Phase 3A Project Cost at the time of tariff determination for the Fourth Control Period if the proposed Phase 3A Project has not been completed and made available for the passengers before 31st March 2024. The Authority therefore decided to consider IDC incurred by the airport operator only till 31st March 2024 with additional IDC

Consultation Paper No: 07/2024-25 Page 93 of 292TRUE UP FOR THE THIRD CONTROL PERIOD beyond 31st March 2024 considered only based on justification for the delay in completion of the Project beyond 31st March 2024.

4.4.128 Accordingly, the Authority proposes that no IDC would be allowed beyond 31st March 2024 as almost ~98.33% of the capex has already been capitalized by 31st March 2024 and also considering that the completion of Phase 3A capex has already been delayed by 21 months compared to the original completion deadline of June 2022.

4.4.129 Further, the Authority also proposes not to consider any adjustment towards RAB for delay in completion of the Project as almost 98.33% of the Project has been capitalized by 31st March 2024 and all the facilities have been made available for the passengers before 31st March 2024, which is consistent with the stipulation for approving capex as decided by the Authority in the Tariff Order for the Third Control Period.

Final Cost of Phase 3A Expansion Capex Proposed to be Considered by the Authority

4.4.130 The Authority after detailed analysis of the submissions made by DIAL regarding Phase 3A Expansion

Capex proposes the final cost as mentioned in the table below:

4.4.131 As can be seen from the table above, based on various adjustments and disallowances explained earlier, the Authority proposes to consider an amount of Rs. 12,079.41 Cr towards Phase 3A Expansion Capex as against Rs. 12,912.54 Cr submitted by DIAL towards true up of RAB for the Third Control Period.

4.4.132 Of the total capex of Rs. 12,079.41 Cr proposed to be considered by the Authority towards Phase 3A Expansion Capex, the cost proposed to be considered for capitalization in the Third Control Period (towards additions to RAB) is Rs. 11,430.07 Cr derived as follows:

Table 60: Capitalization of Phase 3A Expansion Capex proposed to be considered by the Authority for Third Control Period Particulars Amount (Rs. Cr) Total Phase 3A Expansion Capex proposed to be considered by the 12,079.41 Authority as per Table 59 (A)

However, the costs incurred on account of Lease Finance has been allowed as Aeronautical O&M expenses subject to the same being the efficient cost. #Comprise of assets pertaining to Airport Village under Package 1 of EPC Contract i.e. CWIP of Rs. 62.21 Cr as on March 31, 2024 and works amounting to Rs. 139.02 Cr which were not completed as on March 31, 2024.

4.4.133 The Authority also reiterates the following proposals with respect to Phase 3A Expansion Capex: • No adjustment has been made in the RAB for delay in completion of capex as the Project was able to meet the deadline of 31st March 2024 as stipulated by the Authority as explained in

4.4.129. • No IDC would be allowed pertaining to Phase 3A Expansion Capex beyond 31st March 2024 as explained in 4.4.127. • Any upward revision in the GST Input Tax Credit (presently considered as Rs. 295 Cr) based on actuals would be trued up at the time of tariff determination for the Fifth Control Period as explained in 4.4.77.

• GST pertaining to the claims from EPC Contractor would be trued up based on actuals net of ITC, if any, at the time of tariff determination for the Fifth Control Period as explained in

4.4.119.

Authority’s Examination of General Capex of the Third Control Period

4.4.134 The Authority in the Tariff Order for the Third Control Period had approved aeronautical portion of general capex of Rs. 1,328.24 Cr for the Third Control Period as mentioned in the table below:

Table 61: Aeronautical Portion of General Capex approved by the Authority in the Third Control Period FY Ending March 31, 2020 2021 2022 2023 2024 Total (Rs. Cr) General Capex approved by the Authority in Tariff

4.4.135 Further, the Authority decided to true up the asset addition to RAB including General Capex based on actuals at the time of tariff determination for the Fourth Control Period.

4.4.136 The Authority noted the general capex incurred and capitalized by DIAL in the Third Control Period as

provided in the table below:

Table 62: General Capex incurred and capitalized by DIAL for the Third Control Period FY Ending March 31, 2020 2021 2022 2023 2024 Total (Rs.

4.4.137 Overall, the Authority noted that the general capex actually capitalized by DIAL in the Third Control Period (Rs. 931.86 Cr) is lower than the capex approved by the Authority (Rs. 1,328.24 Cr) in the Tariff

Order for the Third Control Period.

4.4.138 The Authority noted that some of the major capex items approved in the Third Control Period have either been postponed to the Fourth Control period or dropped by DIAL for various reasons. The Authority

Consultation Paper No: 07/2024-25 Page 95 of 292TRUE UP FOR THE THIRD CONTROL PERIOD also noted DIAL’s submission that the same is on account of Covid-19 pandemic and consequent change in priorities with regards to some of the general capex items.

4.4.139 The Authority also noted that DIAL had also undertaken certain schemes/works under general capex in the Third Control Period that were not envisaged at the time of submission of MYTP for the Third Control Period based on the operational and other regulatory requirements.

4.4.140 The Authority’s observations on the status of the major capex items under General Capex approved in

the Tariff Order for the Third Control Period as follows:

(CTX) for in line proposal has been discussed in the General Capex XBIS at T3 for the Fourth Control Period.

The Authority noted that trials are ongoing and Concept of Operations is yet to be finalised by CISF & BCAS. Capex is proposed to be carried out in the 2 Body Scanners 154.00 Fourth Control Period by DIAL after finalization by CISF & BCAS. Hence this proposal has been discussed in the General Capex for the Fourth Control Period.

Underpass at Shiv Murthy NH8 to provide direct access to the airport from Southern side. As per the Minutes of Meeting (MoM) dated 17th September 2021, the meeting was called by MoCA on 10th September 2021 to discuss various interfacing issues and status of clearance/ consent from different Southern Access stakeholders and statutory bodies (AAI, DIAL and Road (SAR) – 3 150.00 NHAI) regarding execution of Southern Access Dwaraka Road. During the meeting, MoCA directed DIAL to Expressway share 50% of the cost of construction (i.e.) Rs. 300 Cr.

An amount of Rs. 150 Cr, being share of DIAL, has been paid. The amount is yet to be capitalized in the Third Control Period as NHAI is yet to complete their portion of work.

Automated EBS 4 75.00 Capex dropped by DIAL.

System ASD is required for emergency power systems.

Provision of ASD Provision has been made through other AGL Automatic 5 64.00 Switching Device upgrade schemes. Hence, the Capex was not

(ASD) incurred and proposed to be dropped by DIAL.

4.4.142 The Authority’s analysis of the major capex items capitalized by DIAL in the Third Control Period are

as follows: i. Civil, Electrical & associated work for Apron stands between L1 & M1 including AGL system

upgrade: The Authority noted DIAL’s submission that the flexible pavement of taxiway was converted into rigid pavement due to operational reasons. Associated works related to Electrical & AGL works were also executed along with the same. Upgradation of AGL system as required by DGCA which included individual lamp control, changing to LED from halogen, etc. across airside carried out except Phase 3A areas. It also includes dismantling existing pavement, preparatory works and construction of apron stands between taxiway M1 – L1.

ii. Resurfacing and Rehabilitation of Runway 10/28: The Authority noted DIAL’s submission that Runway 10/28 and associated taxiways have developed multiple distresses due to ageing.

Rehabilitation of the Runway and its associated taxiways was done by DIAL. Initially, it was planned to rehabilitate only the touch-down area of the Runway 10/28, however, major rehabilitation of Civil & AGL Works were carried out for entire length of Runway along with

Consultation Paper No: 07/2024-25 Page 97 of 292TRUE UP FOR THE THIRD CONTROL PERIOD associated Taxiways based on observations from DGCA. The cost incurred for this work has been examined and found to be reasonable.

iii. SITC of Crash Fire Tenders (CFT) for Aircraft Rescue and Firefighting (ARFF): The Authority noted DIAL’s submission that in addition to the CFTs considered at the time of MYTP for the Third Control Period, 5 Additional Crash Fire Tenders were installed to provide ARFF coverage for the New Runway 11L/29R (by commissioning of new Fire station 5) and to meet the response time for additional TWYs including ECT. The cost of procurement of CFTs were compared with the recent procurement by other PPP Airports and is found to be reasonable.

iv. Creation of CISF Camp: The Authority noted that DIAL had to create a new camp for CISF in lieu of the old camp which had to be demolished to enable Phase 3A construction. It was also noted that the work was awarded to the contractor who emerged as the lowest bidder in the competitive bidding.

v. SITC of Disabled Aircraft Recovery Kit: The Authority noted that the capex is required to comply with DGCA directive related to provision of Disabled Aircraft recovery kit at 6 major airports in India. The equipment that will enable faster resumption of operations during aircraft incidents on the runways. The recovery process will include ground preparation, aircraft lifting, de-bogging, tethering, towing, and all other associated aspects of both narrow and wide-body aircraft. The equipment was purchased from M/s. Kunz GMBH Germany who emerged as the lowest bidder in the competitive bidding and accordingly the cost is found to be reasonable.

vi. Rehabilitation of Airside Pavements & associated work: The Authority noted that the capex was required to mitigate distress generation on the airside pavements with advanced technology for repair & rehabilitation of pavements for quicker response & increased availability for operations.

The cost incurred for this activity is in line with the cost incurred for similar works carried out earlier by DIAL and as per the DSR published by CPWD and accordingly considered reasonable. vii. The Authority noted that apart from the above, the capex also included various items viz.

flooring of the terminal, ATRS, construction/ extension of central stores, biometric access system, installation of LED lights, CMS upgrades, etc. The cost was compared with that of similar purchases made by DIAL previously and found to be reasonable.

4.4.143 The Authority after analysis of the major items of the general capex through the independent consultant

proposes to make the following adjustment: i. The cost towards Civil, Electrical & associated work for Apron stands between L1 & M1 including AGL system upgrade as submitted by DIAL is Rs. 96.80 Cr. However, the Authority based on assessment through the independent consultant proposes to consider an amount of Rs.

84.34 Cr against the same based on the purchase order submitted by DIAL for the same. ii. Based on the above, the Authority proposes to consider a cost of Rs. 432.52 Cr for the major items of general capex as mentioned above as against cost of Rs. 444.98 Cr submitted by DIAL.

The total adjustment proposed to be made by the Authority works out to Rs. 12.46 Cr due to non-submission of details/ Purchase Orders by DIAL.

4.4.144 In addition to the above, the Authority also analyzed the other items under general capex through the independent consultant and found that the cost considered by DIAL for capitalization is justified and reasonable on account of mandatory regulatory and operational requirements and the rates considered are reasonable as examined by the Authority through its independent consultant/Aviation Expert.

Consultation Paper No: 07/2024-25 Page 98 of 292TRUE UP FOR THE THIRD CONTROL PERIOD Accordingly, the Authority proposes not to make any adjustments with respect to the cost of other items under general capex.

4.4.145 Based on the above analysis, the Authority proposes to consider an amount of Rs. 919.40 Cr for general capex in the Third Control Period as against an amount of Rs. 931.86 Cr capitalized by DIAL.

4.4.146 The Authority also noted that an amount of Rs. 527.11 Cr of general capex has been recognized as CWIP as on 31st March 2024 as per Table 62 (which also includes an amount of Rs. 150 Cr paid by DIAL towards Underpass at Shiv Murthy junction but yet to be capitalized as NHAI has not completed the project in its entirety). The Authority noted that the CWIP of Rs. 527.11 Cr is proposed to be capitalized in the Fourth Control Period by DIAL. The details regarding the same are discussed in the subsequent chapters on RAB for the Fourth Control Period.

Summary of the Authority’s Analysis on General Capex for the Third Control Period

4.4.147 Based on the above, the General Capex for the Third Control Period as submitted by DIAL in the MYTP for the Fourth Control Period viz-a-viz the general capex proposed to be considered by the Authority is

Authority’s Examination on Asset Allocation proposed by DIAL regarding Asset Additions towards True Up for the Third Control Period

4.4.148 The Authority through its independent consultant segregated the asset additions proposed to be considered in the Third Control Period into aeronautical and non-aeronautical based on the methodology decided by the Authority in the Tariff Order for the Third Control Period.

4.4.149 The principles adopted for segregation of assets is as follows:

Aeronautical Assets • All assets that are exclusively utilised for Aeronautical activities under Schedule 5 of OMDA are treated as Aeronautical assets. • Capital Expenditure on Reserved Activities (as defined in OMDA) like Customs, Immigration, security, health meteorology, plant and animal quarantine are classified as Aeronautical assets.

• Assets related to the services bought under the scope of Aeronautical Services through the decision of the Hon’ble TDSAT dated April 23, 2018 (E.g. Fuel Farm).

Non-Aeronautical Assets • All assets that are exclusively utilised for Non-Aeronautical activities covered under Schedule 6 of OMDA are treated as Non-Aeronautical assets. It may be noted that Cargo and Ground Handling services are treated as Non-aeronautical services as per Schedule 6 of OMDA.

Consultation Paper No: 07/2024-25 Page 99 of 292TRUE UP FOR THE THIRD CONTROL PERIOD • Common Use Terminal Equipment (CUTE) and Common Use Self Service (CUSS) software are classified as Non-Aeronautical Assets in accordance with the DGCA AIS number 7/2007 dated 28 September 2007 and OMDA read along with section 13 of the AERA Act.

Common Assets • Assets for which the benefits or use cannot be exclusively linked to either Aeronautical or Non- Aeronautical are classified as Common Assets. • Common Assets which are situated within the terminal buildings are apportioned to Aeronautical activity in the ratio of the space allocated for Aeronautical and Non-Aeronautical services.

• Common assets which are situated outside the terminal buildings are apportioned to Aeronautical activity based on an appropriate cost driver. However, in the absence of any information regarding the location of the asset or a specific cost driver, a reasonable ratio has been determined by the Authority through its Independent Consultant based on the review of the FAR and other records of the Airport.

4.4.150 The Authority through its independent consultant analyzed the assets on a case-to-case basis and in case of any discrepancies identified in allocation, appropriate reclassification has been made for such assets.

4.4.151 The following ratios have been computed and considered for appropriate segregation of Common assets between Aeronautical and Non-aeronautical assets for the Third Control Period. i. Terminal Building ratio DIAL submitted the allocation of assets in Aeronautical and Non-Aeronautical activities based on floor area of each of the Terminal i.e., T1, T2, T3 demarcated space between Aeronautical and Non- Aeronautical area based on the study conducted by Jacobs Consultancy on behalf of DIAL in 2011. The Authority through its independent consultant considers this demarcated floor space to be an appropriate basis for asset allocation for terminal assets, aligning with the methodology considered by DIAL. The ratios for apportionment of common assets within the Terminal Building across all the Terminals are as

per the table below:

Table 66: Terminal Building Ratios proposed to be considered by the Authority for Apportionment of Common Assets within Terminal Building Particulars Ratios Terminal 1 84.00% Terminal 2 84.20% Terminal 3 84.07%* *The Authority has considered Terminal Building Ratio of 84.07% for T3 consistent with the treatment by the Authority in the Tariff Order for the Third Control Period based on Independent Study on Efficient O&M undertaken by the Authority.

ii. New Udaan Bhawan (NUB) The support functions for the management of the entire airport operations are looked after from the administrative office at New Udaan Bhavan near T3 of the Airport. All the assets related to the New Udaan Bhavan are allocated into Aeronautical/Non-Aeronautical based on the weighted average floor space of all the three terminals.

iii. Common Offices of the Senior Management The NUB houses the senior management of the GMR Group, also on the board of DIAL and has a common office facility for the management in the NUB. Since the total cost of these common group facilities are 100% accounted for in the books of DIAL segregated based on the weighted average floor space of all the terminals, the segregation basis is revisited, to exclude the proportion of expenditure that should have been borne by the other companies in the group. Since, this proportion of expense cannot

Consultation Paper No: 07/2024-25 Page 100 of 292TRUE UP FOR THE THIRD CONTROL PERIOD be computed, all assets for the development of office of the Senior Management are segregated in the proportion of 50:50.

iv. Common Transit Houses DIAL has taken 10 transit houses on lease in Delhi for use by the company for various meetings of the senior management. At these transit houses, DIAL has incurred improvement costs which were capitalized in the books of accounts and included in the RAB.

Since the purpose of use of these transit houses cannot be accurately segregated to Aeronautical and Non-Aeronautical services, it is assumed that the transit house is used in a 50:50 proportion for Aeronautical and Non-Aeronautical services.

4.4.152 Based on the above-mentioned principles and ratios, the impact of the reclassification exercise on asset

additions for the Third Control Period is as follows:

4.4.152.1 The Authority based on the above-mentioned asset allocation principles and ratios, reclassified certain assets from the Aeronautical asset additions submitted by DIAL for the Third Control Period. The revised Aeronautical Asset Additions proposed to be considered by the Authority after factoring in the

reclassification impact is provided below:

4.5.1 DIAL made the following submissions with regard to the Weighted Average Cost of Capital for the Third Control Period.

Cost of Equity:

4.5.2 DIAL has considered cost of equity as approved by the Authority in the Tariff Order for the Third Control Period i.e. 15.41%.

Cost of Debt:

4.5.3 DIAL has considered effective cost of debt i.e. 10.55% for the Third Control Period computed based on the debt outstanding in each of the years of the Control Period. The basis for the cost of debt towards

True Up for the Third Control Period is as shown in the table below:

Table 74: Cost of Debt Calculation submitted by DIAL towards True Up for the Third Control Period FY ending March 31, (Rs. Cr) 2020 2021 2022 2023 2024 Average Principal 8,773.92 12,031.02 12,031.02 11,252.25 13,252.25 Cost of Debt 10.06% 10.24% 10.83% 10.84% 10.68% Effective Cost of Debt 10.55%

4.5.4 The Effective Cost of Debt has been arrived at based on the weighted average of Cost of Debt based on the average principal outstanding for the years in the Third Control Period.

Calculation of WACC:

4.5.5 DIAL considered the same methodology for calculation of WACC as adopted by the Authority in the Tariff Order for the Third Control Period and the WACC as calculated by DIAL stands at 13.08% with notional debt and equity at 48% and 52% respectively. The calculation of WACC is shown in the table

below:

Table 75: WACC submitted by DIAL for the Third Control Period as per MYTP for the Fourth Control Period Particulars Cost of Funds Gearing Effective rate Equity 15.41% 52.00% 8.02% Debt 10.55% 48.00% 5.06% WACC 13.08% Decisions taken by the Authority regarding WACC for the Third Control Period as per the Tariff

Order for the Third Control Period

4.5.6 The Authority vide decision No. 5.6.1 and 5.6.2 of the Tariff Order for the Third Control Period decided to consider Cost of Equity as 15.41% based on the Independent Study and Cost of Debt as 9.87% based on the assessment of effective cost of Rupee Term Loans and effective cost of existing bonds subject to a ceiling of additional 50 bps which shall be trued up based on actuals in the Fourth Control Period.

4.5.7 The Authority vide decision No. 5.6.3 of the Tariff Order for the Third Control Period decided to consider notional debt-equity ratio of 48%:52% as per the Independent study.

Consultation Paper No: 07/2024-25 Page 106 of 292TRUE UP FOR THE THIRD CONTROL PERIOD

4.5.8 The Authority vide decision No. 5.6.4 of the Tariff Order for the Third Control Period decided to consider RSD as part of the notional debt to arrive at WACC.

4.5.9 The Authority vide decision No. 5.6.5 of the Tariff Order for the Third Control Period decided to consider WACC of 12.75% for the Third Control Period based on the above.

Authority’s Examination regarding issues pertaining to WACC towards True Up for the Third Control Period as part of the tariff determination exercise for the Fourth Control Period

4.5.10 The Authority examined the submission made by DIAL and noted that DIAL has adopted Cost of Equity as 15.41% which is consistent with the decision taken by the Authority during the tariff determination for the Third Control Period. Hence, the Authority proposes to consider the Cost of Equity as 15.41% towards True Up for the Third Control Period.

4.5.11 The Authority has noted DIAL’s submission of Cost of Debt as 10.55% towards True Up for the Third Control Period. The Authority noted that the calculation is based on the YoY Cost of debt weighted by the outstanding Principal portion of the Debt Outstanding. The Authority through its independent consultant has verified the actual cost of debt based on the CA certificates submitted by DIAL.

4.5.12 The Authority in the Tariff Order for the Third Control Period allowed Cost of Debt as 9.87%. The Authority had also allowed true up based on actuals at the time of tariff determination for the Fourth Control Period subject to a ceiling of additional 50 bps. Given the fact that the Cost of Debt based on actuals as submitted by DIAL is 10.55%, the Authority proposes to restrict the Efficient Cost of Debt to

10.37% arrived at by adding 50 bps to the cost of debt of 9.87% allowed by the Authority in the Tariff

Order for the Third Control Period as it was well known to DIAL that the maximum debt rate likely to be allowed by the Authority shall be capped at 9.87% p.a. subject to a ceiling of an additional 50 bps.

4.5.13 The Authority consistent with the decision taken at the time of tariff determination for the Third Control Period proposes to consider RSD as part of the notional debt to arrive at WACC.

4.5.14 The Authority proposes to consider the Debt-Equity proportion of 48:52 as decided in the Tariff Order for the Third Control Period. The resulting WACC proposed to be considered by the Authority works out to 12.99% as shown in the table below:

Table 76: WACC proposed to be considered by the Authority towards true up for the Third Control Period Particular Cost of Funds Gearing Effective rate Equity 15.41% 52.00% 8.02% Debt 10.37% 48.00% 4.97% WACC 12.99% Authority’s Proposal regarding WACC for the Third Control Period Based on the material before it and based on its examination, the Authority proposes the following with

i. DIAL entered into lease in June 2019 towards guest houses at Mumbai for the purpose of visits of senior officials for banking/financing works in Mumbai to reduce the boarding costs. In this regard, DIAL paid a security deposit of Rs. 6 Cr to Lessor.

ii. Subsequently, due to Covid-19, the visits to Mumbai were not as expected, hence it was decided by DIAL to discontinue the arrangement and settle the liability through mutual discussion with the Lessor.

iii. The Lessor had initially proposed to deduct the rental for 3 years considering the lock-in period which worked out to Rs. 5.04 Cr (i.e. Rs. 14 lakh per month for 3 years). After negotiations with the Lessor, it was finally decided by DIAL to settle the compensation at Rs. 4.40 Cr.

The fund is only spent on promotions & advertisements to increase footfall for the concessionaires. It is also utilized for sensitizing Airport users about the facilities and services available at the Airport for concessionaires. Some of the major heads under which

these funds are utilized are as follows: • Marketing collaterals like flyers, brochures, banners, hoardings at the Airport. • Ambience creation during marketing and promotional events. • Marketing surveys/researches towards consumer preference of brands.

• Appointment of consultants to focus on enhancing passenger spend through analytics, training, visual merchandising and experience.

Corporate Costs Allocation:

4.6.87 The Authority analyzed DIAL's submissions regarding allocation of Corporate costs for the Third Control Period.

4.6.88 The Authority sought clarifications on the details of entities, cost pertaining to each of the entities, nature of services offered and the basis for allocation of costs of each of the entities to DIAL. The clarifications

provided by DIAL are as follows: i. Corporate costs pertain to allocations of cost of services provided by GMR Airports Limited (GAL, shareholder of DIAL) and GMR Airports Infrastructure Limited (GAIL, holding company of GMR Airports Limited) to DIAL. Both GAL and GAIL have corporate departments which support their airport companies/ SPVs and charges them for use of resources involved in carrying out these activities. The allocation of costs is based on the report submitted by Deloitte Touche Tohmatsu Private Limited in 2022 which contains cost drivers for allocation of cost

Consultation Paper No: 07/2024-25 Page 125 of 292TRUE UP FOR THE THIRD CONTROL PERIOD incurred by the group companies for specific services provided to DIAL. As per the report, cost drivers have been identified for each of the departments (or a group of similar departments) ii. The weighted average of asset size of business is considered as the cost driver for allocation of costs incurred by GAL while the primary cost drivers for allocation of costs incurred by GAIL are number of employees and asset size.

4.6.89 Based on the above, the break-up of corporate cost allocation for both GAL and GAIL is provided in the

table below:

4.6.97 The Authority took cognizance of the statutory provisions of the Companies Act, 2013 towards

allowance of CSR expenses and the extract of the same has been provided below: i. Section 135 (1) of Companies Act, 2013 states that ‘Every company having net worth of rupees five hundred crore or more, or turnover of rupees one thousand crore or more or a net profit of rupees five crore or more during immediately preceding financial year shall constitute a Corporate Social Responsibility Committee of the Board consisting of three or more directors, out of which at least one shall be an independent director.’ Further section 135(5) states that ‘The Board of every company referred in section 135(1), shall ensure that the company spends, in every financial year, at least two percent of the average net profits of the company made during the three immediately preceding financial years, in pursuance of its Corporate Social Responsibility’.

4.6.98 In this regard, the Authority is of the view that the CSR is a mandatory Social Responsibility of the Company (as per Section 135(1) of Companies Act). As the CSR expenditure is to be incurred by Companies out of their net profits, it is to be regarded as an element of appropriation of Net Profits and not as a part of their Operating Expenditure. Therefore, CSR expenses could not be construed as a pass- through expenditure of the companies, otherwise, it would defeat the very purpose of the social responsibility entrusted on the companies.

4.6.99 Further, Section 37(1) of Income Tax Act also disallows CSR expenses, as these are not considered expenses incurred wholly and exclusively for the purpose of business of the entity.

4.6.100 As mentioned in para 4.2.3 of this Consultation Paper, the Authority proposes not to consider CSR expenses as part of Aeronautical O&M expenses for the Third Control Period.

4.6.101 Further, the Authority consistent with the decision taken in the past proposes not to consider Donations and Provisions for Bad Debts as part of Aeronautical O&M expenses for the Third Control Period.

The Authority noted that DIAL as part of cost efficiency and cash flow management refinanced its bonds and high interest cost bearing NCD. As part of refinancing, DIAL had to incur various cost in the form of upfront fee, prepayment charges, processing fee, etc. The details of amortization of borrowing costs/upfront fee and other incidental expenses are tabulated below:

2022. During FY 2024, Rs. 41.73 Cr was paid as redemption premium for the partial repayment (25%) of NCDs (Rs. 744 Cr out of Rs. 3,257 Cr) originally due in October 2025. ii. The Authority noted that DIAL incurred routine bank transaction charges which comprise of charges on remittances, BG commission, Facility charges, TRA charges, Escrow Fees, etc. Further, the Bank Charges also comprise of interest on OD/working capital facilities/vendor financing availed by DIAL for management of the airport and operations during the Covid-19.

iii. The Authority also noted that DIAL paid interest of Rs. 40.01 Cr in FY 2022 on Refundable Security Deposits (RSD) from Bharti Reality SPVs lying with DIAL pending receipt of approval of the Concept Master Plan for the commercial development. DIAL entered into Development Agreement with five SPVs of Bharti Realty on 28th March 2019 for commercial property development and in pursuant to the same, DIAL received first tranche of RSD to the extent of Rs. 360 Cr and the same formed part of RSD of Rs. 1,500 Cr which was utilized towards part-funding the Phase 3A Expansion Capex. As per the agreement, DIAL was required to obtain approval of the Concept Master Plan for the said property development within the stipulated timeframe.

However, the approval of Concept Master Plan relating to commercial development got delayed by about 2 years. On account of the delay in approval of Concept Master Plan and consequent delay in granting right to Bharti Realty SPVs to develop the project, DIAL was obligated to pay interest on the first tranche of the RSD at the rate of 5.6% p.a. for 2 years of delay and the total interest paid by DIAL was Rs. 40.01 Cr.

4.6.107 The Authority noted that the upfront fee and other borrowing costs (towards refinancing of debt) and redemption premium (towards early settlement of debt) incurred by DIAL resulted in reduction of borrowing costs and hence there is a necessity to incentivize DIAL for the same. The routine bank transaction charges could be considered as regular expenses towards banking operations. Further, the interest incurred on OD facilities availed during Covid-19 was required for cash flow management.

Accordingly, the Authority proposes to consider the amortization of borrowing costs, redemption premium, routine bank transaction charges and interest on OD facilities as mentioned in Table 126.

4.6.108 The Authority noted that the interest paid on RSD from Bharti Realty SPVs was on account of delay in obtaining relevant approval by DIAL for the commercial project. Further, the Authority also noted that the interest paid was in the nature of compensation for non-performance of obligation by DIAL as per the Agreement pertaining to a commercial project (being a Non-aeronautical activity) which cannot be treated as Aeronautical costs. Accordingly, the Authority proposes not to consider the interest of Rs.

40.01 Cr on RSD as part of Aeronautical Bank Charges for FY 2022.

4.6.109 The Authority also noted that Bank Charges for FY 2024 submitted by DIAL include lease set up costs and IDC of Rs. 37 Cr towards lease financing for equipment under Phase 3A. The Authority analyzed that the costs include lease agreement set up cost of Rs. 8.51 Cr and notional IDC of Rs. 28.49 Cr. It may be noted that the IDC considered by DIAL is notional and there is no IDC required to be incurred by DIAL in lease financing. Accordingly, the Authority proposes to disallow the notional IDC of Rs.

28.49 Cr from the Bank Charges in FY 2024.

4.6.133 The Authority sought clarification from DIAL on the nature of IT related expenses. DIAL clarified that the expenses paid to Wipro Airport IT Services Limited (WAISL) are towards various IT related services as per the agreement entered into between the parties.

4.6.134 The Authority noted that DIAL awarded the concession for management of entire IT systems and services at IGIA (excluding Enterprise IT equipment and services owned by DIAL) to Wipro Limited.

Consequently, a JV in the name of Wipro Airport IT Services Limited (WAISL) was formed to act as the concessionaire.

4.6.135 The details of the services provided by WAISL are as follows:

Table 138: Services provided by WAISL to IGIA Service Description Server availability, SAN/NAS availability, Data Backup, Storage and Retrieval, Data Centre services Applications Performance, System Recovery and Availability Application services Application Module Availability and Application Quality Enhancement Ensure Network Availability and in time resolution of network related Network services complaints IT helpdesk service for user and resolution of IT related queries within stipulated End User services time.

Timely Configuration Updates, Change management, asset management, Virus Common services Signature File Updates, Information Security Risk Event Notification and Mitigation, Firewall Security, Reporting Timeliness and Accuracy, Billing Timeliness and Accuracy and Customer Satisfaction.

4.6.136 The Authority noted that the contract is in the nature of cost contract which ensured minimum subsistence level payment to WAISL, the service provider. As per terms of the Master Service Agreement, in case the receivables of WAISL exceed the subsistence level in the previous financial year, the concessionaire has to pay DIAL a concession fee equivalent to the excess of receivables over subsistence level. However, in case the receivables of WAISL is lower than the minimum subsistence level as per the agreement, DIAL is required to pay WAISL to meet its subsistence level.

4.6.137 During FY 2021, DIAL was required to pay WAISL to meet its subsistence level (i.e. to meet the deficit between cash inflows and outflows as the revenue reduced due to Covid-19). Accordingly, DIAL paid Rs. 46 Cr to WAISIL to meet the deficit.

4.6.138 Further, the Authority noted that in addition to the above, DIAL paid an amount of Rs. 19 Cr to WAISL towards shortfall in meeting the cost of Tech Refresh as per the Master Service Agreement.

4.6.139 The Authority found the justification provided by DIAL as reasonable and accordingly proposes to allocate the expenses based on GFA ratio. The expenses proposed to be considered by the Authority are

as follows:

4.6.160 This cost has been adjusted in the final cost to be allowed as part of RAB for the purpose of true up for the Third Control Period as the lease costs are being allowed as part of O&M Expenses. Towards the lease financing, DIAL is required to make lease payments to the lessor on a monthly basis at the rate of Rs. 18 per month per Rs. 1,000 of cost i.e. Rs. 7.20 Cr per month. The equipment leasing period is for 7

Consultation Paper No: 07/2024-25 Page 138 of 292TRUE UP FOR THE THIRD CONTROL PERIOD years. Towards this, DIAL has paid security deposits of Rs. 100 Cr which is expected to fetch interest income at the rate of 7% p.a.

4.6.161 DIAL proposes to consider the lease payments under O&M expenses for the purpose of tariff determination, whereas in the books of accounts, the leased equipment would form part of the Fixed Assets as Right of Use (ROU) assets. The terms of the lease are as follows:

Table 150: Terms of the Finance Lease as per DIAL Particulars Value Value of the Equipment (Rs. Cr) 400 No. of Months 84 Lease Payment per Month (Rs. Cr) 7.20 Security Deposit (Rs. Cr) 100 Interest Income on Security Deposit (%) 7%

Further, the Authority noted that DIAL has not considered interest income on the security deposits which needs to be netted off against the lease payments.

4.6.164 Accordingly, the Authority proposes to consider lease payments at the Efficient Cost of Debt proposed to be considered by the Authority for the Third Control Period i.e. 10.37% p.a. The lease payment per month at an interest rate of 10.37% p.a. works out to Rs. 6.72 Cr and interest income on security deposits works out to Rs. 7 Cr.

below: i. DIAL pays property tax based on the settled principles for assessment of the property tax by the area covered by the South Delhi Municipal Corporation (SDMC) and Delhi Cantonment Board

(DCB). It may be noted that area pertaining to Terminal 1 come under the jurisdiction of DCB while all other area come under the jurisdiction of SDMC with respect to payment of property tax. ii. The property tax charged by SDMC in FY 2023 was Rs. 11.44 Cr. SDMC revised the computation methodology in FY 2024 and as a result property tax applicable for FY 2024 is Rs. 34.79 Cr.

iii. DCB passed an assessment order dated 15th June 2020 levying property tax of Rs. 867.21 Cr per annum against its earlier assessment of tax of Rs. 9.13 Cr per annum and raised the total demand of Rs. 2,601.63 Cr for 3 FYs i.e. 2017 to 2019. DIAL filed a Writ Petition before the Hon’ble High Court of Delhi challenging the assessment order dated 15th June 2020. Hon’ble Delhi High Court set aside the previous assessments and ordered that fresh assessments be done and tax shall be levied as per Section 73(b) of the Cantonments Act, 2006 by DCB. After assessment, Fresh

Assessment orders were received by DIAL from DCB: • FY 2017 to FY 2023 - Rs. 73.56 Cr (after adjusting Rs. 17.31 Cr already paid by DIAL for the period) on 01st February 2024 • FY 2007 to FY 2016 – Rs. 55.58 Cr on 18th April 2024

Consultation Paper No: 07/2024-25 Page 142 of 292TRUE UP FOR THE THIRD CONTROL PERIOD iv. It may be noted that DCB has not allowed rebate of 25% as provided in the final order of Hon’ble High Court. However, after receipt of above orders, DIAL paid Rs. 50.85 Cr (rebate applied on total amount including Rs. 17.31 Cr already paid) against order dated February 01, 2024 for FY 2017 to FY 2023 and Rs. 41.68 Cr against order dated April 18, 2024 for FY 2007 to FY 2016 and respectively for above two demands after considering rebate of 25% as directed in the final

order of Hon’ble Delhi High Court. The payment against order dated February 01, 2024 was made in FY 2024 while the payment against order dated 18th April 2024 was made in FY 2025. The matter was heard on 10th May 2024 and the matter has been disposed off as DCB has agreed to provide the rebate.

4.6.182 The property tax payments have been also examined based on documentary evidences in the form of CA certificates.

4.6.183 The Authority proposes to consider property tax on actual payment basis for the Third Control Period.

5. TRAFFIC PROJECTIONS FOR THE FOURTH CONTROL PERIOD

5.1 DIAL’s Submission regarding Traffic Projections for the Fourth Control Period

5.1.1 DIAL has mentioned that the OMDA requires DIAL to develop an initial Master Plan (completed in Sept’2006) and provides an obligation to revise the master plan once in every ten years or at shorter interval if traffic forecast or other reasons require an earlier assessment.

5.1.2 DIAL developed an Initial Master Plan in Sep’2006 and later appointed M/s Landrum & Brown (L&B) to review the master plan in 2015. L&B is an industry expert in master planning and strategy, airfield and airspace, terminal planning and design, development, environment, financial/business planning, ground transportation, commercial development and aviation planning services.

5.1.3 L&B completed the Master Plan in 2016 considering the various forecasts and accordingly proposed various development activities based on the triggering events/time periods. In accordance with the master plan of L&B, Phase 3A project was initiated by DIAL in 2019. However, in 2020 aviation business faced an unprecedented challenge in the form of Covid-19 pandemic. The pandemic severely impacted the traffic in first half of 2020 and saw a slow recovery post reopening from various phases of lockdowns. In addition to Covid-19, the Noida International Airport in Jewar is expected to compete for IGIA’s market share and has proposed to commence its operations by April 2025.

5.1.4 Considering changes in business scenario, DIAL has appointed M/s ICF International Inc. (ICF), for performing a traffic study of IGI Airport and provide the traffic forecasts.

5.1.5 Key considerations by the ICF for undertaking the traffic forecast for DIAL are as discussed below: • ICF has developed a bottom-up view forecast for IGI Airport in the short term (FY 24 – FY 25) and a top-down forecast for the long term (FY 26 – FY 29).

• ICF performed an analysis of actual traffic from AAI’s monthly publications to gain insights into how IGIA performed in FY 2024 and where they are in terms of recovering from the Covid-19 pandemic. • ICF reviewed schedules from M/s. OAG Aviation to get an understanding of:

o Airlines’ plans to bring back capacity at the market level after the impact of Covid-19 pandemic, over the short term. o Impact and recovery of the Indian market because of Go First shutdown. • Unconstrained forecasts were first developed. ICF tested regressions of multiple markets and explanatory variables. Based on the best fit in the long term, the ICF forecast was driven by elasticities to GDP and airfares. The variables used include:

o Indian GDP for the domestic market. o A blend of India and World GDP for the international market based on point-of-sale data. • Over the forecast period, ICF tapered elasticities to more mature market rates to reflect the growth profile of more developed airports, considering the aspects of the Indian market which are expected to continue supporting relatively strong growth, such as differentiating between Tier 1 and Tier 2/3 growth outlooks. From an unconstrained passenger demand, ICF had forecasted ATMs based on a combination of seats per ATM, fleet mix and load factors.

• ICF has also analysed the impact of the second airport in National Capital Region i.e. Noida International Airport on passenger and cargo traffic at IGIA.

Consultation Paper No: 07/2024-25 Page 157 of 292TRAFFIC PROJECTIONS FOR THE FOURTH CONTROL PERIOD

5.1.6 Based on the above, ICF has come up with Traffic forecasts for the Fourth Control Period and the growth rates for each of the traffic categories i.e. Passenger Traffic, ATM and Cargo Traffic as ascertained from

the ICF Traffic forecasts are as shown in the table below:

5.2 Authority’s Examination regarding Traffic Projections for the Fourth Control Period

5.2.1 The Authority has examined the historical trend in Traffic including past five-year traffic growth rates and noticed that the traffic has improved significantly post Covid–19 and reached pre-Covid-19 level in FY 2023. Passenger traffic in FY 2024 improved by 12.77% when compared to the previous year.

5.2.2 The Authority has also taken note of the report of International Air Transport Association (IATA) dated 9th January 2025 on Air Passenger Market Analysis for the month of November 2024, which indicate stable passenger growth for India.

IATA in its report dated 9th January 2025 had presented the following: • The industry’s total Revenue Passenger-Kilometer (RPK) increased by 8.1% YoY in November, continuing to exceed historical records. Available Seat-Kilometer (ASK) rose by 5.7% YoY lagging demand growth.

• The Passenger Load Factor (PLF) improved by 1.9 percentage points compared to the previous year, reaching 83.4%, an all-time high for November. • Domestic traffic overall grew by 3.1% YoY. India led the main markets this month with a 13.3% rise in RPK. All monitored markets showed stable demand growth, although seat capacity in some areas plateaued.

• International passenger traffic for the industry surged by 11.6% YoY in November. Carriers in the Middle East and Asia Pacific experienced higher growth, significantly contributing to global momentum. International RPK in Asia Pacific is now just 0.5% below pre-pandemic levels.

5.2.3 The Authority noted the Traffic forecasts for IGI Airport as per the study conducted by ICF for the Fourth Control Period which is a dedicated study for IGIA taking into consideration the macro and micro variables pertaining to IGIA.

5.2.4 The Authority has also noted that the ICF study has taken into consideration the possible impact of the upcoming Noida International Airport (NIA) which shall also cater to a material portion of the traffic at the National Capital Region. The Authority has taken cognizance of the following observations of ICF

in this regard: i. Although NIA will have the spill over of traffic from IGIA in the coming years, NIA’s own market stimulation will also play a major role in the medium to long term. As capacity constraints limit IGIA’s ability to accommodate demand, ICF has forecasted the traffic to be spilled over to NIA. However, NIA’s ability to act as a relief airport will depend on the extent of its network and capacity.

ii. Based on present travel times, 58% of the population in the total catchment area of IGIA and NIA may prefer IGIA over NIA, 31% may prefer NIA over IGIA and 11% may prefer both.

Residents on the western side, particularly from Haryana, shall be more inclined to use IGIA due to better travel times. Many districts in Eastern Uttar Pradesh have shorter travel times to NIA, making it a more attractive option for local residents.

iii. The catchment area of IGIA is more urbanized (53% urban population) and economically stronger (higher GDP per capita) while the catchment area of NIA is less urbanized (29% urban population) and has a lower GDP per capita, which typically correlates with a lower propensity to fly. According to survey data from 2018, Eastern UP, which is expected to be a feeder region for NIA, accounted for only 10% of passengers at IGIA which indicates limited air travel

Consultation Paper No: 07/2024-25 Page 159 of 292TRAFFIC PROJECTIONS FOR THE FOURTH CONTROL PERIOD demand from this area to IGIA, potentially benefiting NIA. The catchment area for IGIA and

NIA as per the ICF study is depicted in the figure below:

Figure 4 : Catchment area for IGIA and NIA as per ICF study iv. Further, based on the comparative analysis of IGIA and NIA on key parameters viz. Location, Convenience, Capacity, Costs for Passengers, Scale, Loyalty, International operations and Travel time, ICF concludes that IGIA has a clear competitive advantage on many important aspects as compared to NIA, which will have more passengers from eastern UP and parts of Haryana with lesser travel time.

5.2.5 Based on the above considerations, the Authority noted the traffic forecasts as per the ICF study

conducted by DIAL for the Fourth Control Period is as follows:

Table 180: Traffic Forecasts as per the Study by ICF for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Total Passenger Traffic (MPPA) Domestic 56.45 59.42 63.41 67.05 70.15 316.48 Domestic YoY Growth % 4.15% 5.26% 6.72% 5.74% 4.63% International 21.15 22.17 23.36 24.46 25.43 116.56 International YoY Growth % 8.60% 4.84% 5.37% 4.70% 3.99% Total 77.59 81.59 86.77 91.51 95.58 433.04 ATM – Overall* (‘000s) Domestic 362.55 380.56 404.97 427.03 445.54 2,020.64 Domestic YoY Growth % 7.87% 4.97% 6.42% 5.45% 4.33% International 113.75 118.82 124.74 130.13 134.83 622.27 International YoY Growth % 6.91% 4.46% 4.99% 4.32% 3.61% Total 476.30 499.38 529.72 557.16 580.37 2,642.92

5.2.6 The Authority noted that DIAL in the MYTP for the Fourth Control Period has submitted the Traffic Projections only for Billable ATMs and not for Overall ATMs. The Authority sought clarifications from DIAL on the category-wise exclusions in ATMs (i.e. ATMs that were not billed) for arriving at Billable ATMs. The category-wise exclusions in ATMs for arriving at Billable ATMs for FY 2024 is as follows:

Table 181: Category-wise Exclusions in ATMs for FY 2024 FY ending March 31 2024 ATM – Overall (‘000s) Domestic 336.09 International 106.40 Total 442.49 Exclusions* (i.e. ATMs not Billed) (‘000s) Aircrafts with less than 80 seats (including flights under RCS#) 6.42 Helicopters 0.13 Total 6.55 ATM – Billable (‘000s) Domestic 167.18 International 54.61 Total 221.79 *No landing charges shall be payable in respect of a) aircraft with a maximum certified capacity of less than 80 seats, being operated by domestic scheduled operators at airport, b) helicopters of all types and c) DGCA approved flying school/flying training institute aircrafts.

#As per DIAL, No RCS flights with capacity more than 80 seats operated at IGIA in FY 2024.

5.2.7 The Authority noted that DIAL in its Traffic Projections for the Fourth Control Period has considered projections for Passenger Traffic and Cargo Traffic as per the study by ICF while the Billable ATMs for the Fourth Control Period has been projected based on the Passenger Traffic growth (YoY increase) derived as per the study by ICF with Billable ATMs for FY 2024 as the base.

5.2.8 The Authority is of the view that DIAL’s projections for Billable ATMs for the Fourth Control Period based on the Passenger Traffic growth rate as per ICF’s forecasts is not reasonable and justifiable especially when ICF in its study has forecasted the growth rates for Overall ATMs for IGI Airport for the Fourth Control Period.

5.2.9 Accordingly, the Authority proposes to project ATMs (Overall and Billable ATM) for the Fourth Control Period based on the growth rate for Overall ATM (YoY increase) derived as per the study by ICF with ATMs (Overall and Billable ATM) for FY 2024 as the base as follows:

Consultation Paper No: 07/2024-25 Page 161 of 292TRAFFIC PROJECTIONS FOR THE FOURTH CONTROL PERIOD Table 182: Growth Rates proposed to be considered by the Authority for ATMs for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Domestic ATMs 7.87% 4.97% 6.42% 5.45% 4.33% International ATMs 6.91% 4.46% 4.99% 4.32% 3.61%

Note: Above growth rates are derived from ICF Forecasts for Overall ATMs

5.2.10 Based on the above, the ATMs (Overall and Billable ATM) proposed to be considered by the Authority

for the Fourth Control Period is as follows:

5.3 Authority’s Proposal regarding Traffic Projections for the Fourth Control Period Based on the material before it and its analysis, the Authority proposes the following regarding Traffic

projections for the Fourth Control Period:

5.3.1 To consider Traffic as per Table 184 for the Fourth Control Period which shall be trued up based on actuals at the time of tariff determination for the Fifth Control Period.

Consultation Paper No: 07/2024-25 Page 164 of 292CAPEX, DEPRECIATION AND RAB FOR THE FOURTH CONTROL PERIOD

6. CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE FOURTH CONTROL PERIOD

6.1 Background

6.1.1 Regulatory Asset Base (RAB) is one of the essential elements in the process of tariff determination. The return to be provided on the RAB constitutes a considerable portion of the Aggregate Revenue Requirement/ Target Revenue for an Airport Operator. To encourage the participation of the private sector in airport development and operations, investors must be fairly compensated for the capital investment made. At the same time, to safeguard the interests of the airport users, it must be ensured that the aeronautical capital additions are necessary, reasonable and justified.

6.1.2 The Authority noted that DIAL needs to develop IGI Airport in a phased manner during the period of operations to cater the increasing annual passenger traffic (domestic and international) and annual cargo handling capacity, along with ancillary facilities as per Master Plan 2016 of IGIA. Further, development of the airport includes construction/modernization and procurement of various assets as described in the

OMDA such as: • Runways, taxiways, apron, administrative offices, aircraft parking bays, retail and associated facilities. • Terminal Building and facilities and • Construction of required approach roads.

6.1.3 The Independent Consultant appointed by the Authority has performed due analysis of the submissions made by DIAL towards Aeronautical Capital Expenditure, Depreciation and RAB. In this respect, the Independent Consultant/Aviation Expert has performed the following functions:

i. Reviewed the capex plan submitted by DIAL in view of various technical studies undertaken by DIAL, Airport Master Plans, BOQs (wherever provided), Copies of Letter of Intent (LOI), Letter of Award (LOA), Purchase Orders and Work Orders etc., wherever provided. The Independent Consultant also considered the responses of DIAL to the clarification sought in relation with CAPEX plan from time to time.

ii. Sought documentary evidence along with the process of approval for capex including competitive bidding process for award of various works to the contractor(s), if applicable. iii. The Independent Consultant/Aviation Expert also visited IGIA in the months of August and September 2024 focusing specifically on review of current airport operations and proposed airport development plans and the necessity for the same.

6.1.4 The Authority through its independent consultant/Aviation Expert had examined the entire CAPEX plan proposed by DIAL in detail including CWIP projects and the Expansion Capex for the Fourth Control Period, considering the historical traffic trends and future traffic estimates such that only essential, reasonable, aeronautical capital expenditure is considered as part of RAB for the Fourth Control Period.

This was done with a view to encourage the investment and maintain a balanced approach between sustainable operations of the airport and the interest of the airport users.

6.1.5 Further, the Authority shall along with the necessity of the capex, has assessed the feasibility of implementing the proposed capex within the remaining years in the Fourth Control Period. It is imperative that DIAL completes the proposed capex within the time frame as otherwise the airport users

Consultation Paper No: 07/2024-25 Page 165 of 292CAPEX, DEPRECIATION AND RAB FOR THE FOURTH CONTROL PERIOD shall end up bearing the burden of the capex funding requirement in the form of higher tariff without having access to the facilities.

6.1.6 Considering the above, the Authority had rationalized the CAPEX submitted by DIAL based on verification of item rates and optimization of the capacity augmentation proposed by DIAL and accordingly proposed capital additions for the Fourth Control Period.

6.1.7 Accordingly, the Authority has presented its views in the following order: i. Expansion Capex for the Fourth Control Period. ii. General Capex for the Fourth Control Period iii. Capital Work in Progress carried forward from Third Control Period to the Fourth Control Period iv. Aeronautical Allocation of Capital Expenditure for the Fourth Control Period v. Aeronautical Depreciation for the Fourth Control Period vi. Regulatory Asset Base for the Fourth Control Period

6.2 DIAL’s Submission regarding Capital Expenditure (CAPEX), Depreciation and Regulatory Asset Base (RAB) for the Fourth Control Period Capex Plan for the Fourth Control Period

6.2.1 DIAL in the MYTP for the Fourth Control Period has submitted Expansion and General Capex plan along with carry forward of Capex from the Third Control Period for the Fourth Control Period as

follows:

Note: DIAL in MYTP for 4th CP submitted cost of Rs. 5,625.33 Cr towards Capex in 4th CP. However, as part of clarifications on the MYTP submissions, DIAL provided detailed break-up of estimates and submitted revised cost of Rs. 5,497.69 Cr for 4th CP. The Authority for its analysis proposes to consider the revised submissions by DIAL.

A. Expansion Capex for the Fourth Control Period

6.2.2 DIAL in the MYTP for the Fourth Control Period has submitted that due to projected increase in traffic, IGI Airport would reach its maximum capacity for catering to the needs of the International passengers by FY 2026 and would reach 90% of handling capacity of the Terminal 3 by FY 2026. In order to cater to the increasing passenger traffic, DIAL proposes the following expansion capex during the Fourth

Control Period:

Similarly, the cost submitted for A3 and A4 above has also been revised by DIAL in subsequent submissions. The Authority for its analysis proposes to consider the revised submissions by DIAL.

6.2.3 The Authority noted that for the examination of the Capex for the Fourth Control Period, the Authority proposes to consider revised submissions of DIAL as shown in the table above.

6.2.4 The details of the expansion capex submitted by DIAL are as follows:

Construction of Code E and C parking stands

6.2.5 IGI Airport is being developed as a hub airport in India and it requires adequate infrastructure to support the hub operations. Currently, DIAL has limited number of wide body (Code E) stands to support long haul aircrafts. Airlines in India have placed large orders for fleet addition and are expanding their fleet across narrow and wide body aircrafts.

6.2.6 DIAL has been getting requests from Airlines to provide night parking for the aircrafts at IGIA.

Additionally, at IGIA, many of the parking stands remain occupied due to grounding of aircrafts and hence number of stands available to support daily operations is not sufficient.

6.2.7 In order to support the increasing demand of stands from airlines and also to facilitate seamless operation for all kind of aircraft operations, DIAL proposes to develop parking stands in phases to cater to wide body and narrow body operations.

6.2.8 The details of development of parking stands proposed at IGIA as submitted by DIAL is provided in the

table below:

Consultation Paper No: 07/2024-25 Page 167 of 292CAPEX, DEPRECIATION AND RAB FOR THE FOURTH CONTROL PERIOD Construction of Pier E

6.2.10 IGIA Master Plan 2016 proposes for addition of Pier E with Domestic in-fill to the eastern side of existing integrated Terminal 3 (T3) for enhancing Terminal 3 domestic Capacity by 10 MPPA.

6.2.11 The existing domestic capacity of DIAL will get exhausted by FY 2028 and hence will require a new Pier E to be added to Terminal 3. This will result in allocation of Pier A, B and C (C is currently used for Domestic Operations) for the International traffic while Pier D and E will be completely utilized for domestic operations.

6.2.12 Around 3,600 sq.m. of Passenger Terminal Building (T3) requires reconfiguration and refurbishment as part of this project. The salient features of the proposed development (Pier E and domestic Infill) are:

Domestic Infill: • The total area of domestic infill is approximately 12,650 sq.m., covering 2 levels for serving departures, arrivals and transfer passengers. • The domestic infill mainly accommodates security screening processing area, administration offices and few retail, transfers etc.

Pier E: • Pier E will have 12 contact stands. • Pier E apron will have 6 remote stands for serving the remote parking of code C aircraft stands. • Pier E consists of three levels, namely Departures, Arrivals and Apron level.

• The extent of area considered for MEP works would be approximately 55,532 sq.m. • The apron of Pier E consists of two types of pavements (flexible and rigid pavements). • The scope includes Airport Systems and Apron Lighting as well.

6.2.13 Further, DIAL is in the process of engaging a Technical Consultant for updating the existing Master Plan in accordance with the requirement of OMDA. DIAL shall intimate the Authority in case of any major change in the Master Plan of IGIA in due course.

6.2.14 The completion of Pier E by FY 2028 would result in an increase in the passenger handling capacity by 10 MPPA and would cater to the need of IGIA for the Fourth Control Period.

6.2.15 The hard cost of the project is Rs. 1,500 Cr and is estimated to be funded at debt equity ratio of 70:30 while IDC is proposed to be funded entirely through debt.

6.2.16 The projected Passenger Handling capacity of IGIA across all the terminals post construction of Pier E

would be as shown in the table below:

General Capex for the Fourth Control Period

6.2.18 DIAL has informed that they are currently operating two old terminals (T2 and T3) where many of its equipment have either surpassed their useful life or are running close to their end of life. DIAL with the introduction of new technology has been extending the life of many of these equipment. However, to provide enhanced passenger experience, DIAL is required to invest in replacing/upgrading these equipment on a timely basis. Further, there are requirements for compliance/ directives from various regulatory authorities including BCAS, DGCA etc. which requires replacing/ installing new equipment.

In order to meet the regulatory requirement, capital expenditure needs to be incurred. Such capital expenditure forms major portion of the General Capex proposed for the Fourth Control Period.

Airport Users Consultative Committee (AUCC) Meeting

6.3.2 The Authority noted that DIAL conducted Airport Users Consultative Committee (AUCC) Meeting on 06th January 2025 for consultation on the proposed capex for the Fourth Control period. The meeting was attended by representatives from various airport stakeholders including but not limited to MoCA, International Airport Transport Association (IATA), Federation of Indian Airlines (FIA), Indigo, Air India, Akasa Air, Spicejet, Air India SATS, British Airways, Cathay Pacific, Delhi Metro Rail Corporation (DMRC), Taj SATS, Association of Private Airport Operators (APAO), CISF, Immigration, various Trade Bodies and associations among others.

6.3.3 As per the minutes of the meeting, the Authority observed that DIAL had broadly discussed the

following with the stakeholders: a. Key Performance Indicators (KPI) of the Airport b. Traffic Forecasts for the Fourth Control Period c. Key Capex projects (Expansion and General capex) for the Fourth Control Period as mentioned

below: • Terminal 3 Pier C Conversion to International

Consultation Paper No: 07/2024-25 Page 174 of 292CAPEX, DEPRECIATION AND RAB FOR THE FOURTH CONTROL PERIOD • Terminal 3 Pier E Construction • Construction of Code C and E Parking Stands • Terminal 2 Refurbishment • General Capex ▪ CT-XBIS for PESC Area ▪ HBS X-ray replacement with CT machines at T3 ▪ Full Body Scanners ▪ Crash Fire Tenders ▪ Rehabilitation of RWY 11R/29L (Civil Works) ▪ Upgradation of AGL CMS Software update & Hardware replacement ▪ Expansion Works of Airports Operations Centre (APOC)

6.3.4 As per the minutes of AUCC meeting, it can be seen that the stakeholders made important observations in relation to the proposed capex projects for the Fourth Control Period as well as other aspects viz.

Operations, Safety & Security, Passenger Experience, Non-aero revenue etc.

6.3.5 Some of the key observations made by the stakeholders are mentioned below: i. BCAS instructed on adequate safety measures and enquired about provision for installation of CT-XBIS machines at T2. ii. CISF instructed on working out extra space/width required for installation of CT-XBIS and Full Body Scanners (FBS) and inclusion of Country Terrorist Contingency Plan (CTCP) infrastructure on city side in the Capex when Pier E comes up.

iii. Air India enquired on the need for T2 refurbishment when T4 is to be built as per the existing master plan, reasons for not considering Phase 3B as part of capex, capex on increasing the throughput of transfer screening facilities, enhancement of I to I transfer space, increased infrastructure to improve passenger movement between terminal and remote parking stands, implementation of digiyatra based boarding and decongesting approach roads and approach ramp to T3.

iv. British Airways enquired on the efficiency of baggage offload of arrival passengers after conversion of Pier C to International. v. FIA enquired on Automated People Mover (APM) system, additional details on general capex, capacity enhancement on account of T2 refurbishment and initiatives on increasing non-aero revenue.

vi. IATA enquired about leveraging self-service option through kiosks instead of additional immigration counters, mitigation of disruptions at Pier D Apron during Pier E construction, single security hold process for both domestic and international passengers, effective utilization of existing parking stands, impact of new parking stands on Minimum Connecting Time and bussing operations, remote/centralized screening for carry-on baggage and internal efficiency improvement targets after establishment of APOC.

vii. Indigo enquired about the daily throughput of APM envisaged between T1 and T3 and whether APM will be chargeable to passengers.

6.3.6 The Authority also noted DIAL’s responses to the stakeholder comments. Some of the responses of the

key observations raised by the stakeholders are mentioned below: i. DIAL will not compromise on the safety of the existing terminal during conversion of Pier C and construction of Pier E and has engaged one of the leading engineering consultants to take care of the technical details. Further, 12 CT-XBIS machines are planned for replacement at T2 which has been factored in the total number of 90 machines proposed in capex.

Consultation Paper No: 07/2024-25 Page 175 of 292CAPEX, DEPRECIATION AND RAB FOR THE FOURTH CONTROL PERIOD ii. DIAL has worked the layout for installation of CT-XBIS machines in consultation with the vendors. Working has already been done for accommodation of CT-XBIS machines in the current PESC area. Further, DIAL is still awaiting concept of operations for deployment of FBS.

The CTCP measures and traffic circulation have been accounted for before the design stage. iii. T4 is part of the existing master plan. T2 refurbishment is being considered instead of T4 because of lower capex in T2 and as a short-term measure to meet current demand. The master plan is currently under review. I to I transfer capacity was enhanced 3 times after Phase 3A Expansion. Digiyatra has been implemented at all boarding gates to ensure smooth boarding process for airlines.

iv. After Pier C conversion to international, 3 baggage belts currently handling domestic passengers will be used for international traffic which will enhance the baggage handling capacity of international traffic.

v. Phase 3B primarily had T4. It was earlier planned that T2 would be demolished and T4 would be constructed. Due to higher capex requirement in building T4, T2 refurbishment is being taken up in 4th CP.

vi. DIAL replied that APM is already under bidding stage and is proposed to be developed on Design, Build, Operate and Transfer model. It is expected to be operational by March 2028. The movement would be bi-directional both from T1 to T3 and vice-versa. DIAL expects throughput of 40,000 to 50,000 passengers/day initially which would be scaled up to 80,000 to 90,000 passengers/day by increasing the frequency. APM will not be chargeable for transfer passengers while for rest of the passengers, it will be chargeable.

vii. T2 refurbishment is being undertaken not for increasing its capacity but for various other reasons. DGCA has made observations for apron refurbishment and boarding bridges. Structural audit by IIT Madras also suggested certain improvements. Further, DIAL is taking a number of initiatives to increase the number of shops in the next five years.

viii. DIAL has proposed 40 additional immigration counters after Pier C conversion as per BCAS guidelines. DIAL will ensure that operations at Pier D apron are not disrupted during Pier E construction.

ix. DIAL has also asked the Airlines to remove the defunct grounded aircrafts for effective utilization of existing parking stands. x. DIAL also provided an update on the road projects currently being implemented to improve connectivity to the Airport (Southern access road, NSG junction, Gurgaon to airport road and Approach ramp to T3).

6.3.7 The Authority has examined the Capex plan (Expansion Capex as well as General Capex) submitted by DIAL for the Fourth Control Period and has rationalized it based on various factors viz. necessity, feasibility and reasonability of costs. The following sections explain in detail the Authority’s analysis of the above-mentioned capex items.

A. Expansion Capex for the Fourth Control Period

Construction of Code C and Code E Stands

6.3.70 The Authority noted that DIAL proposes to construct 56 Code C stands at an estimated cost of Rs.

392.26 Cr and 7 Code E stands at a cost of Rs. 126.04 Cr. The Authority through its independent consultant has ascertained that the above-mentioned activity is in consonance with the Master Plan of IGIA.

6.3.71 The Authority noted that the cost of constructing one Code C stand considered by DIAL is Rs. 7.00 Cr.

The detailed basis for the cost submitted by DIAL is given in the table below:

Consultation Paper No: 07/2024-25 Page 187 of 292CAPEX, DEPRECIATION AND RAB FOR THE FOURTH CONTROL PERIOD Table 205: Cost submitted by DIAL towards Construction of Code C Stands No Particulars (Rs.

6.3.72 The Authority noted that the cost estimated by DIAL is based on the purchase order dated 7th July 2018.

6.3.73 The Authority through its independent consultant/aviation expert analysed the submission based on the cost for Pavement works as per the independent study undertaken by KITCO for Phase 3A Expansion Capex of DIAL. Base cost for construction of pavement works as per KITCO independent study is considered and escalated further based on WPI to arrive at the cost for the respective year of execution.

It may be noted that WPI for FY 2022 was unusually high at 12.97%. The same has been moderated to

7.14% based on average of WPI for FY 2021 and FY 2022 consistent with the decision taken by the Authority for other major Airports in the recent past.

6.3.74 Based on the above assessment, the Authority is of the view that the cost per stand considered by DIAL (Rs. 7.00 Cr) is reasonable and hence proposes to consider the same.

6.3.75 The Authority also noted that DIAL proposes to construct a total of 56 stands of which 9 stands are proposed to be constructed in Centaur Hotel area. DIAL has signed lease agreement with the hotel which is expiring only in 2029. The Authority is of the view that it may be difficult for DIAL to construct 9 stands prior to expiry of lease agreement. Hence, the Authority proposes to consider only 47 stands in the Fourth Control Period as against 56 stands considered by DIAL.

6.3.76 Accordingly, the cost for 47 stands based on the unit cost of Rs. 7.00 Cr per stand works out Rs. 329.00 Cr.

6.3.77 The Authority proposes to consider cost of Rs. 329.00 Cr for 47 stands as against cost of Rs. 392.26 Cr submitted by DIAL for 56 stands as mentioned below:

6.3.80 The Authority noted that the cost estimated by DIAL is based on the Purchase Order dated 27th February

2019.

6.3.81 Similar to the assessment of cost for Code C stands, the Authority through its independent consultant/aviation expert analysed the submission based on the cost for Pavement works as per the independent study undertaken by KITCO for Phase 3A Expansion Capex of DIAL. The base cost for construction of pavement works as per KITCO independent study is considered and escalated further based on WPI to arrive at the cost for the respective year of execution. As explained earlier, the WPI for FY 2022 has been moderated to 7.14% based on average of WPI for FY 2021 and FY 2022.

6.3.82 Based on the above assessment, the Authority is of the view that the cost per stand considered by DIAL (Rs. 18.01 Cr) is reasonable and hence proposes to consider the same.

6.3.83 The Authority proposes to consider cost of Rs. 126.04 Cr for the above-mentioned activity as shown in

the table below:

6.3.85 The Authority noted that DIAL proposes to fund the hard cost pertaining to construction of Code C and E stands at a debt/equity ratio of 70:30 while IDC would be funded entirely through internal accruals.

6.3.86 The Authority is of the view that the debt-equity mix and capex phasing considered by DIAL for Code C and E stands as reasonable and accordingly proposes to consider the same for its analysis.

6.3.87 The Authority is also of the view that the interest rate considered by DIAL for the debt proposed for the project (i.e. 10% p.a.) as reasonable and accordingly proposes to consider the same for its analysis.

6.3.88 Based on the revision in the hard cost of the project as per the Authority’s analysis, the Authority has revised the means of finance and IDC for the project.

6.3.89 The IDC proposed to be considered by the Authority for Code C and E stands is as shown in the table

below:

Consultation Paper No: 07/2024-25 Page 190 of 292CAPEX, DEPRECIATION AND RAB FOR THE FOURTH CONTROL PERIOD A4. Construction of Pier E at Terminal 3

6.3.92 The Authority noted that DIAL proposes to construct Pier E at Terminal 3 at an estimated hard cost of Rs. 1,511.36 Cr (excluding IDC). The Authority through its independent consultant/aviation expert has verified that the above activity is part of the Master Plan of IGIA and is of the view that this activity has to be carried out necessarily to enable the airport to cater to the consistently growing Pax traffic at IGIA.

6.3.93 The Authority through its independent consultant/aviation expert found that DIAL has estimated cost for these works based on the relevant cost under the Phase 3A contract with L&T with suitable escalation based on WPI till the year of execution. The detailed breakup of cost for each of the activities submitted

by DIAL is as shown in the table below:

Table 212: Cost submitted by DIAL towards Construction of Pier E E Pier E (Rs. Cr) Cost submitted by DIAL E1 T3 Infill 282.00 E2 T3 PTB reconfiguration & refurbishment 40.00 E3 Pier E 759.00 E4 Link to Pier D 116.00 E5 Pier E Apron (Rigid) 42.00 E6 Taxiway Code C 31.00 E7 Flexible Pavement (ULD Storage, GSE Roads, Perimeter Road) 29.00 E8 Apron Lighting 4.00 E9 Stands Marking 0.88 Total Hard Cost (A) 1,302.90 Design & PMC charges (B) 104.23 Contingencies (C) 104.23 Total Soft Cost (D=B+C) 208.46 Total Cost excluding IDC (A+D) 1,511.36

6.3.94 The Authority noted that construction of Pier E involves activities like construction of Taxiway for Code C flights, stands marking, Apron lighting, construction of flexible pavement, Infill works, PTB reconfiguration and refurbishment and construction of link to Pier D etc.

6.3.95 Similar to the assessment carried out for Code C and E stands, the Authority through its independent consultant/aviation expert analysed the cost for Pier E based on the costs as per the independent study undertaken by KITCO for Phase 3A Expansion Capex of DIAL. Base cost for various works as per KITCO independent study is considered and escalated further based on WPI to arrive at the cost for the respective year of execution. As explained earlier, the WPI for FY 2022 has been moderated to 7.14% based on average of WPI for FY 2021 and FY 2022.

6.3.96 Based on the above assessment, the Authority is of the view that the cost adopted by DIAL for Taxiway and Pavement works are reasonable and hence the Authority proposes to consider the same. The Authority however notes that the cost adopted by DIAL for Apron and terminal building works are not optimal and efficient and hence proposes to consider the costs as per independent study (with escalation based on WPI as mentioned earlier) for Apron and Terminal building related works. Accordingly, the hard cost for Pier E proposed to be considered by the Authority is Rs. 1,045.21 Cr.

6.3.97 The Authority analysed the submission made by DIAL and found that the soft costs (design, PMC, preliminary & preoperative expenses and contingency) estimated by DIAL at ~16% of hard costs is not reasonable and not optimal and appears to be overestimated.

6.3.98 In its estimate, DIAL has considered Rs. 104.23 Cr as contingency expenses. However, such expenditure doesn’t come as a separate line item at the time of capitalization of the asset as it is part of incurred cost.

Considering this aspect, the Authority proposes to exclude the contingency expenses in its examination.

Consultation Paper No: 07/2024-25 Page 191 of 292CAPEX, DEPRECIATION AND RAB FOR THE FOURTH CONTROL PERIOD Apart from this, for Apron and refurbishment works, soft cost varies from 3% to 5% and Pier E expansion works has fixed design and hence soft costs including contingency cannot be more than 8%.

DIAL has considered 8% as Design and PMC work, which looks reasonable. Hence the Authority proposes to consider soft costs at 8% of total hard costs and the total soft costs proposed to be considered by the Authority has been arrived as Rs. 83.62 Cr as against DIAL’s submission of Rs. 208.46 Cr.

6.3.99 Accordingly, the total cost excluding IDC proposed to be considered by the Authority for Pier E is Rs.

1,128.83 Cr as mentioned in the table below:

6.3.100 The Authority noted that DIAL proposes to fund the hard cost pertaining to construction of Pier E at a debt/equity ratio of 70:30 while IDC would be funded entirely through debt.

6.3.101 The Authority is of the view that the debt-equity mix and capex phasing considered by DIAL for construction of Pier E as reasonable and accordingly proposes to consider the same for its analysis.

6.3.102 The Authority is also of the view that the interest rate considered by DIAL for the debt proposed for the project (i.e. 10% p.a.) is reasonable and accordingly propose to consider the same for its analysis.

6.3.103 Based on the revision in the hard cost of the project as per the Authority’s analysis, the Authority has revised the means of finance and IDC for the project.

6.3.104 The IDC proposed to be considered by the Authority for Pier E is shown below:

Consultation Paper No: 07/2024-25 Page 193 of 292CAPEX, DEPRECIATION AND RAB FOR THE FOURTH CONTROL PERIOD B1. General Capex related to Project & Engineering

6.3.111 The Authority noted that DIAL has submitted a cost of Rs. 1,567.83 Cr under Project & Engineering which constitute major portion of General Capex. It includes activities like procurement of various equipment to meet BCAS requirement, rehabilitation and refurbishment of facilities and development of new facilities.

6.3.112 The Authority through its independent consultant/aviation expert analysed the submission made by DIAL and moderated cost of various activities by rationalising the number of machines to be procured, disallowance of non-essential activities etc. and proposes a cost of Rs. 1,176.01 Cr against the submission of Rs. 1,567.83 Cr.

6.3.113 The detailed analysis for each activity under Project & Engineering is shown in the table below:

Table 218: Cost proposed to be considered by the Authority for Project & Engineering under General Capex Cost Proposed Cost S. to be Particulars (Rs. Cr) submitted by Rationale/ Remarks No considered by DIAL the Authority A Project & Engineering The Authority noted that BCAS has directed Airports to change PESC with CT-XBIS. In this regard, DIAL proposes to install 90 machines. The Authority noted that final orders on usage are yet to be promulgated and also besides that procurement, installation and commissioning also takes significant time.

Therefore, the Authority proposes to CT- XBIS for PESC consider 44 machines for the Fourth A1 area at IGIA (Terminal 350.00 246.40 Control Period. Further, based on 1&3) vendor quote, the Authority proposes to consider an amount of Rs. 5.6 Cr per machine which translates to Rs.

246.40 Cr for 44 machines.

DIAL can procure additional machines on requirement basis over and above the quantum of machines proposed by the Authority. Cost of additional machines would be allowed on incurrence basis subject to reasonableness and efficiency.

The Authority noted that 15 Inline T3 Dep. HBS X-ray baggage screening X ray machines replacement with CT were installed in 2010. BCAS has machines along with directed Airports to replace X-ray A2 Matrix server, 186.00 186.00 screening with CT technology, and workstations & hence DIAL proposes to replace all peripherals (BCAS existing units in a phased manner

circular & end of life) (replace 8 units in FY 2027 and 7 units in FY 2028). Cost for this activity is

The Authority based on the analysis through its independent consultant/aviation expert is of the view that cost is reasonable and hence proposes to consider this cost.

The Authority noted that DIAL is using DFMD at PESC area for passenger frisking. BCAS has directed DIAL to replace all DFMD with Full Body Scanner. DIAL proposes 45 Full Body Scanner for 90 CT - XBIS.

The Authority has proposed to A3 Body Scanners 145.00 70.40 consider only 44 CT-XBIS machines and accordingly proposes to consider only 22 Body Scanners (i.e. ratio of 1:2). Further, based on vendor quote, the Authority proposes to consider an amount of Rs. 3.2 Cr per body scanner which translates to total cost of Rs.

70.40 Cr.

The Authority noted that RWY11R/29L was constructed in 2008 and due to the impact of ageing and max load of traffic, center line crack is observed throughout the runway. DIAL proposes Rs. 90 Cr towards civil works for this activity.

RWY 11R/29L (Civil A4 90.00 80.00 works) The Authority based on the analysis through its independent consultant/aviation expert proposes to consider Rs. 80 Cr. The rationalization in cost proposed by the Authority is on account of higher inflation rate considered by DIAL.

The Authority noted that system software and hardware are installed in 2017 and they have a useful life of 5 years. DIAL estimated Rs. 55 Cr for Upgradation of AGL this upgradation activity and the CMS Software update scheduled replacement is in FY 2030.

6.3.155 The Authority in the Tariff Order for the Third Control Period decided to consider depreciation for expansion assets by considering a weighted average for depreciation for building and plant & machinery at a proportion of 65:35 respectively. The depreciation rate arrived at by the Authority is 4.51% which was considered for expansion assets for the Third Control Period.

6.3.156 The Authority consistent with the earlier decision proposes to consider the depreciation rate of 4.51% assuming a similar proportion of Building and Plant and Machinery amongst the assets proposed to be added for the Fourth Control Period. The depreciation amount shall be trued up based on actual asset addition and depreciation during the tariff determination for the subsequent Control Period.

6.3.157 The Authority based on the adjustments proposed in the capex for the Fourth Control Period proposes

to revise the depreciation as provided below:

7. WEIGHTED AVERAGE COST OF CAPITAL (WACC) FOR THE FOURTH CONTROL PERIOD

7.1 DIAL’s Submissions regarding WACC for the Fourth Control Period Cost of Equity

7.1.1 DIAL in the MYTP for the Fourth Control Period has considered 15.41% as Cost of Equity. The Cost of Equity proposed by DIAL is consistent with the Cost of Equity proposed as per the Independent study conducted by IIM Bangalore at the time of tariff determination for the Third Control Period.

DIAL proposes to consider the same Cost of Equity for the Fourth Control Period.

7.1.2 DIAL in the MYTP for the Fourth Control Period has projected equity base including the expected

reserves and surplus as shown in the table below:

Table 235: Equity Base submitted by DIAL for the Fourth Control Period as per MYTP FY ending March 31 (Rs.

7.1.3 DIAL has projected the cost of debt based on the outflows of the existing loans as on March 31, 2024 at the original drawdown foreign currency rate.

7.1.4 In addition to the existing loans, DIAL proposes to avail fresh loan to meet capital projects i.e.

Construction of Pier E and Construction of Code E and C stands proposed to be carried out in the Fourth Control Period. The projects are proposed to be funded by way of debt and equity in the ratio 70:30. Cost of Debt has been considered as 10%

7.1.5 The details of the debt outstanding along with the cost of debt as submitted by DIAL is as shown in the

table below:

7.2 Authority’s Examination regarding WACC for the Fourth Control Period Cost of Equity

7.2.1 As per the Hon’ble TDSAT order dated April 23, 2018 in the matter of issues raised by DIAL with regards to decisions taken by the Authority in the First Control Period, the Authority had commissioned a separate independent study for evaluation of cost of capital for DIAL for the Third Control Period and the study was entrusted to IIM Bangalore.

7.2.2 The independent study had drawn from the international experience of airports having comparability to IGIA in terms of revenue till, ownership structure and scale of operations and had also studied the regulatory framework of other regulators.

7.2.3 The independent study computed the Cost of Equity at 15.41% by using Capital Asset Pricing Model

and using a notional Debt : Equity ratio of 48%:52%.

7.2.4 The Authority proposes to continue to adopt the recommendations of the independent study in the tariff determination for the Fourth Control Period with regards to the Cost of Equity and notional debt equity ratio and hence has considered 15.41% as the Cost of Equity and notional debt equity ratio of 48%:52% for the Fourth Control Period.

Cost of Debt

7.2.5 The Authority noted the submission made by DIAL with regards to Cost of Debt. The Authority has also assessed the cost of debt in the past, actually incurred by DIAL towards funding the Phase 3A Expansion Project for which debt of Rs. 7,850 Cr has been raised and also the debt raised before the Phase 3A Expansion Project funding exercise which continue to be outstanding during the Fourth Control Period. The Authority has noted that the weighted average cost of debt as assessed by DIAL for the Fourth Control Period is 10.24%.

7.2.6 DIAL has also been able to raise debt at 9.50% recently which is much lesser than the cost of debt proposed by the airport operator for the Fourth Control Period. However, the debt raised by DIAL during the Phase 3A expansion Project, and for the previous financing exercise has been at a much higher cost leading to an overall cost of debt proposed being at 10.24%.

7.2.7 The Authority is in the process of benchmarking cost of debt for all the major airports based on the External Credit Rating of the Airport which shall suggest a suitable spread over a reliable benchmark at the beginning of the Control Period.

7.2.8 The Authority proposes to consider 1-year SBI MCLR at the start of commencement of the Control Period to be the right benchmark to which necessary spread has to be added which should absorb the financing and other associated costs incidental to fund raising activity.

7.2.9 The Authority is of the view that given the External Credit Rating of AA- for DIAL and also considering the situation wherein DIAL had already locked in higher interest rates during a higher

Consultation Paper No: 07/ 2024-25 Page 229 of 292WEIGHTED AVERAGE COST OF CAPITAL (WACC) FOR THE FOURTH CONTROL PERIOD interest rate environment during the Phase 3A expansion project, a spread of 150 bps above the benchmark could be considered as the optimum spread for DIAL.

7.2.10 Considering the above, the Authority proposes to consider efficient cost of debt at 10.15% considering a spread of 150 bps above SBI 1-year MCLR of 8.65% at the beginning of the Control Period.

7.2.11 DIAL should over the next few years be able to optimize the cost of debt given the expected decline in benchmark rates of borrowing and shall take effective steps to raise debt at efficient costs to retire the high cost debt already raised in the past control period so that the interest costs of DIAL gets optimized and the benefits are shared with the airport users.

7.2.12 The Authority has reworked the weighted average cost of capital considering the efficient cost of debt of 10.15%. The Authority proposes to also true up the cost of debt based on actuals or the cost of debt considering the spread of 150 bps plus SBI 1-year MCLR (whichever is lower) at the time of tariff determination for the Fifth Control Period.

WACC for the Fourth Control Period

7.2.13 Based on the above, the Authority proposes to consider the Weighted Average Cost of Capital as

12.89% for the Fourth Control Period based on the Cost of Equity of 15.41% and Cost of Debt of

10.15% and considering the notional gearing ratio of debt-equity of 48%:52% as follows:

Table 238: WACC proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Cost of funds Cost of Equity 15.41% 15.41% 15.41% 15.41% 15.41% Efficient cost of debt 10.15% 10.15% 10.15% 10.15% 10.15% Gearing Equity 52.00% 52.00% 52.00% 52.00% 52.00% Debt 48.00% 48.00% 48.00% 48.00% 48.00% WACC for the Year 12.89% 12.89% 12.89% 12.89% 12.89%

7.2.14 The Authority notes that since the debt equity mix had been decided by the Authority considering the efficient capital structure and the interest of all the Stakeholders, the Authority proposes to not true up

the D:E ratio based on notional gearing of 48%:52% during the tariff determination for the next Control Period.

7.3 Authority’s Proposals regarding WACC for the Fourth Control Period Based on the material before it and based on its examination, the Authority proposes the following

regarding Weighted Average Cost of Capital for the Fourth Control Period:

7.3.1 To consider cost of equity, efficient cost of debt, notional debt-equity ratio and WACC for the Fourth Control Period as per Table 238.

7.3.2 To true up the Cost of debt for the Fourth Control Period based on actuals (or) SBI average 1-year MCLR plus 150 bps (whichever is lower) at the time of tariff determination for the Fifth Control Period.

Consultation Paper No: 07/ 2024-25 Page 231 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD

9. AERONAUTICAL OPERATION AND MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD

9.1 DIAL’s Submission regarding Operation and Maintenance (O&M) Expenses for the Fourth Control Period Operation and Maintenance (O&M) Expenses Considerations by DIAL for the Fourth Control Period

9.1.1 DIAL has submitted that the following points have been considered for estimation of Aeronautical Operation and Maintenance (O&M) expenses for the Fourth Control Period: • Base Year: In order to form a basis of forecasting expenses for the Fourth Control Period, DIAL has considered FY 2024 i.e. the last year of the Third Control Period as base year and applied growth percentage over it.

• Inflationary increase: DIAL has considered inflationary increase on certain expenses. The CPI inflation rate of 4.6% is considered for the Fourth Control Period based on the results of 87th round of professional forecasters on macroeconomic indicators by RBI.

• Impact of Phase 3A expansion: Post expansion of Terminal 1, total area has increased by 22% and the passenger handling capacity has been increased by 52%. The increased terminal area shall lead to increase in expenses viz. Repairs & Maintenance, House Keeping, Manpower hire charges and Security expenses as a consequence to manage the increased operational area. The increased passenger handling capacity shall lead to increase in manpower expenses and admin & general expenses.

Details of Head wise O&M Expenses as submitted by DIAL

9.1.2 Manpower Costs: DIAL has projected increase in employee head count at IGIA by ~21% in FY 2025 to cater to the increase in operations post Phase 3A in airside, landside, terminal side and support functions. Further, the Noida International Airport is expected to be commissioned from April’25 within the vicinity of IGIA and hence DIAL is required to increase the manpower compensation by way of increments/retentions and other payments. Thus, DIAL projected the increase in these costs based on inflation of 4.6% p.a. and real growth in manpower cost by 7% p.a. and a further increase in employee requirement due to expansion of Terminal area by 21% in FY 2025 due to Phase 3A, and by 4% in FY 2028 due to Pier E Expansion.

9.1.3 Administrative and General Expenses: i. Rent, Rates & Taxes: These costs are projected to increase year on year based on inflation rate of 4.6% from the base year. ii. Professional and Consultancy expenses: Due to increase in passenger handling capacity, operation of four runways coupled with the expected competition from the Noida International Airport in the near future, DIAL has projected to incur professional and consultancy expenses for various improvements in its processes to sustain its operations. Thus, DIAL has projected increase at inflation rate of 4.6% and real growth of 10% year on year for the entire Fourth Control Period.

iii. Advertisement and Business Promotion: In order to protect the interest of the IGI Airport due to the competition from the Noida International Airport in the near future, DIAL has proposed to attract passenger traffic by way of various advertisements on passenger

Consultation Paper No: 07/ 2024-25 Page 232 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD experience, facilities, service quality and ratings of IGI Airport. Thus, DIAL has projected an increase in expenditure based on passenger traffic growth and inflation year on year. DIAL has considered the base for this expenditure as FY 2023 instead of FY 2024, considering higher than usual expenditure in FY 2024 on account of one-time expenses.

iv. Corporate Cost allocation: DIAL had projected increase in these costs based on growth in manpower costs, increase in the manpower and inflation rate. v. Travelling and Conveyance expenditure: DIAL has projected that these costs would increase in consonance with the increase in the manpower at IGI Airport and inflation year on year.

vi. CSR Expenditure: DIAL has projected the CSR expenditure and considered the amount as part of Aeronautical Operation and Maintenance Costs. vii. Bank Charges: Bank charges are projected based on the estimates of amortization of the transaction costs incurred for availing of the loan facilities for means of finance for the projects.

viii. Other expenses: Other administrative expenditure is related to various miscellaneous expenditure incurred by DIAL including collection charges towards UDF. This expenditure is projected to be increased based on passenger handling capacity, inflation and real growth.

9.1.4 The head-wise break-up of Aeronautical Admin and General expenses submitted by DIAL for the

Fourth Control Period is as follows:

Table 241: Aeronautical Admin and General Expenses submitted by DIAL for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Total (Rs. Cr) Rent 4.05 4.24 4.44 4.64 4.85 22.22 Rates and Taxes 1.06 1.11 1.16 1.21 1.27 5.79 Professional and

9.1.5 Operating Expenses: i. Repairs & Maintenance expenditure: The major part of the repairs and maintenance expenditure are related to the AMC and CMC cost of plant and machinery. DIAL has stated that they have already started replacing few of the plant and machineries in phased manner either due to completion of the useful life of the assets or in line with the requirements of BCAS on various equipment required as part of the issued guidelines. Further, due to expansion of the airport, the number of equipment which is required to be covered under AMC/CMC has

Consultation Paper No: 07/ 2024-25 Page 233 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD increased. Thus, the repairs and maintenance of the plant and machinery is projected to increase in proportion to the increase in the area and inflation costs from the base year. This has a similar effect on the R&M of IT Equipment which are required for the purposes of the operations at IGIA. Due to increase in the total area to be catered for maintenance of civil structure such as buildings, roads and taxiways, the R&M relating to these items are projected to increase in proportion to the increase in the area and inflation costs from the base year.

ii. House Keeping expenses and consumables: The existing terminals of IGIA (T3 and T2) are getting older and post Covid-19 the awareness of the cleanliness and requirement for upkeeping of ambience in surroundings has a greater impact on meeting the service requirement of the OMDA along with the greater passenger experience for users. The completion of Phase 3A led to significant increase in the terminal area of the IGI Airport and the expenditure for housekeeping would increase in consonance with increase in terminal area.

Thus, the projection for housekeeping expenses and consumables are considered to be increased by one time on account of increase in the terminal area and every year on account of inflation as well as growth in manpower cost.

iii. Insurance: DIAL has completed Phase 3A expansion in the second half of FY 2024. Thus, the asset base would increase for the purposes of the payment of insurance premium. This has been considered based on the estimates of the insurance premium on various insurance policies considered by DIAL.

iv. Manpower Hire Charges (Third Party): Post completion of Phase 3A, the operational area to be covered by DIAL would increase and accordingly the expenditure relating to manpower hire charges is projected based on the inflation, growth in manpower cost and one time increase in the expansion factor due to increase in area.

v. Security Expenses: Post completion of Phase 3A, the area to be covered for security purposes would increase and accordingly these expenditure are projected to increase based on the inflation, growth in manpower cost and one time increase based on area expansion factor due to increase in area.

vi. Equipment Lease Rental: DIAL as part of Phase 3A has entered into a finance lease for procurement of the assets worth Rs. 400 Cr. The details of the equipment funded by way of lease finance is shown in the Table 149. The lease payments of these equipment are considered as part of the operating expenditure of DIAL amounting to Rs. 7.2 Cr per month.

9.1.6 The Aeronautical Operating Expenses submitted by DIAL for the Fourth Control Period is as follows:

9.1.7 Utility Expenses: The power and water demand at IGIA is expected to rise due to increase in passenger traffic and increase in terminal area. DIAL has projected increase in power and other utility expenses in proportion to the increase in the area to be served by DIAL along with inflationary increase in tariff by power suppliers.

9.1.8 Airport Operator Fee: DIAL has considered the contractual obligation of the payment of Airport Operator fee at 3% of the projected revenue in line with its earlier submissions.

9.1.9 Property Tax: DIAL has projected the property tax outflows based on the settled principles for the assessment of the property tax by the area covered by the SDMC (South Delhi Municipal Corporation) and DCB (Delhi Cantonment Board). DIAL has projected that the property tax outflow for the Fourth Control Period would be Rs. 34.79 Cr for SDMC and would vary from Rs. 23 Cr in FY 2025 to Rs.

31 Cr in FY 2029 for DCB. Further, DIAL is also expected to discharge pending dues of Rs. 52 Cr to DCB in FY 2025.

9.2 Authority’s Examination of Aeronautical Operation and Maintenance (O&M) Expenses for the Fourth Control Period The Authority examined DIAL’s submissions regarding Aeronautical Operation and Maintenance (O&M) Expenses for the Fourth Control Period taking into account the tariff setting principles detailed at para 1.3.3 of this Consultation Paper to ensure that only the efficient, justified and reasonable expenses are allowed on projection basis for the smooth conduct of Airport operations during the Fourth Control Period.

Consultation Paper No: 07/ 2024-25 Page 235 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD

9.2.1 The Authority noted that DIAL has used the following key growth/ escalation factors for projecting Operation and Maintenance (O&M) expenses for the Fourth Control Period. i. Inflation ii. Terminal Area Increase Factor iii. Manpower Growth Factor

9.2.2 Inflation: The Authority noted that DIAL has considered inflation rate of 4.6% for all years of the Fourth Control Period as per the “Results of the Survey of Professional Forecasters on Macroeconomic Indicators – Round 87” published by the RBI.

9.2.3 Terminal Area Increase Factor: The Authority noted that DIAL considered terminal area increase factor of 21.79% (based on increase in total terminal area on account of Phase 3A Capex) and 6.81% (based on increase in total terminal area on account of Pier E) in FY 2025 and FY 2028 respectively.

9.2.4 Manpower Growth Factor: The Authority noted that DIAL considered manpower growth factor of

20.61% (i.e. 40% of increase in passenger handling capacity of the Airport due to Phase 3A Capex i.e.

51.52%) and 4% (i.e. 40% of increase in passenger handling capacity of the Airport due to Pier E i.e.

10%) in FY 2025 and FY 2028 respectively.

9.2.5 The summary of the key growth/ escalation factors considered by DIAL for projecting O&M expenses

for the Fourth Control Period is as follows:

Table 244: Key Growth/ Escalation Factors considered by DIAL for projecting O&M Expenses FY ending March 31 2025 2026 2027 2028 2029 Inflation 4.60% 4.60% 4.60% 4.60% 4.60% Terminal Area Increase Factor 21.79% - - 6.81% - Manpower Growth Factor* 20.61% - - 4.00% - *40% of increase in passenger handling capacity of the Airport

9.2.6 As per DIAL’s submission, expenses related to Repairs and Maintenance, Housekeeping, Consumables, Manpower Hire Charges, Security expenses and Utility expenses are linked to increase in terminal area while expenses related to Manpower and Admin & General expenses are linked to manpower growth factor.

9.2.7 The Authority after examination of DIAL’s submission of Inflation rate for the Fourth Control Period proposes to consider inflation rate of 4.6% for the Fourth Control Period i.e. FY 2025 to FY 2029 as per the “Results of the Survey of Professional Forecasters on Macroeconomic Indicators – Round 89” published by the RBI (Refer Table 240).

9.2.8 The Authority after analysis of the terminal area increase and manpower growth factors noted that the O&M expenses may not increase in direct proportion to terminal area increase and/or passenger handling capacity due to economies of scale.

9.2.9 Accordingly, the Authority proposes to moderate the terminal area increase and manpower growth factors and propose to consider only 2/3rd of the terminal area and manpower growth factor considered by DIAL.

Consultation Paper No: 07/ 2024-25 Page 236 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD i. Terminal Area Increase Factor: The Authority proposes to consider terminal area increase factor of 14.53% and 4.54% in FY 2025 and FY 2028 respectively as against 21.79% and 6.81% respectively considered by DIAL.

ii. Manpower Growth Factor: The Authority proposes to consider manpower growth factor of

14.53% as against 20.61% considered by DIAL in FY 2025. However, the Authority proposes to consider manpower growth factor of 4.00% as submitted by DIAL in FY 2028 as DIAL’s submission is found to be reasonable.

9.2.10 The summary of the key growth/ escalation factors proposed to be considered by the Authority for projecting O&M expenses for the Fourth Control Period is as follows:

Table 245: Key Growth/Escalation Factors proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Inflation 4.60% 4.60% 4.60% 4.60% 4.60% Terminal Area Increase Factor 14.53% - - 4.54% - Manpower Growth Factor 14.53% - - 4.00% -

9.2.11 The Authority proposes to project O&M expenses for the Fourth Control Period by applying appropriate escalation rates over the Aeronautical portion of respective expenses proposed to be considered by the Authority for FY 2024.

9.2.12 The Authority’s analysis of each of the components of the O&M expenses for the Fourth Control Period

is presented below:

Manpower Expenses:

9.2.13 The manpower expenses are segregated under two heads viz. (i) Salaries, Wages and Bonus and (ii) Staff Welfare expenses.

9.2.14 The manpower expenses submitted by DIAL for the Fourth Control Period is as follows:

Table 246: Aeronautical Manpower Expenses submitted by DIAL for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Total (Rs. Cr) Salaries, Wages and

9.2.15 The Authority analysed DIAL’s submission regarding Salary expenses for the Fourth Control Period and noted that DIAL has considered costs for FY 2024 as the base for projecting the expenses for the Fourth Control Period. DIAL has considered annual growth rate of 7% p.a. along with an inflation rate of 4.6% p.a. i.e. an effective growth rate of 12% p.a. In addition to this, DIAL has considered manpower growth factor of 20.61% in FY 2025 and 4% in FY 2028 respectively.

Consultation Paper No: 07/ 2024-25 Page 237 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD

9.2.16 The Authority assessed the past CAGR of Salary expenses and found that the expenses grew at a CAGR of 9% during the Second and Third Control Period. Accordingly, the Authority is of the view that the growth rates considered by DIAL are well above the historical trend.

9.2.17 The Authority also observed that IGIA is an established airport with the highest passenger traffic among all the major airports in India and must have taken sufficient measures to bring in efficiency in its overall functioning. The Authority also noted that DIAL shall be able to optimize the manpower costs as DIAL over a period of time has invested a lot in technology. Accordingly, the Authority expects the expenses towards Salaries and Wages to grow at a rate marginally higher than the inflation rates.

9.2.18 The Authority, after analysis of the submission as well as past trend, proposes to consider a growth rate of 6% p.a. for Salaries and Wages and also consider manpower growth factor of 14.53% in FY 2025 and 4% in FY 2028.

Staff Welfare Expenses

9.2.19 The Authority also examined DIAL’s submission regarding Staff Welfare expenses for the Fourth Control Period and noted that this expense item has been projected similar to Salary expenses i.e. an effective growth rate of 12% p.a. with expenses for FY 2024 as the base. In addition to this, DIAL has considered manpower growth factor of 20.61% in FY 2025 and 4% in FY 2028 for projecting Staff welfare expenses in the Fourth Control Period.

9.2.20 The Staff Welfare expenses majorly comprise pantry expenses, relocation cost, uniforms/ raincoats, children school fee allowance, get togethers, other allowances, training, insurance (medical, accidental etc.), medical & health facility, professional membership etc.

9.2.21 DIAL claims that the Staff Welfare expenses are directly proportional to the growth observed in the Salaries.

9.2.22 The Authority after analysis of the Staff Welfare expenses noted that average Staff Welfare expenses for FY 2023 and FY 2024 was 4.7% of Salaries and Wages.

9.2.23 Accordingly, the Authority proposes to consider Staff Welfare expenses at 4.7% of Salaries and Wages in the Fourth Control Period.

9.2.24 The Aeronautical Manpower expenses proposed to be considered by the Authority for the Fourth

Control Period is shown in the table below:

9.2.27 The Authority analysed DIAL’s submission wherein Rent expenses are escalated at the rate of inflation for the Fourth Control Period with FY 2024 as the base.

9.2.28 Rent expenses primarily comprise of rentals paid towards the transit guest houses for employees of DIAL. In addition to this, DIAL on need basis incurs rentals towards various equipment/vehicles which are hired on temporary basis.

9.2.29 The Authority based on its analysis noted that the past growth rates (annual as well as CAGR for five year period) of Rent expenses were highly inconsistent on account of the nature of these items.

9.2.30 The Authority is of the view that DIAL’s projection of Aeronautical Rent Expenses based on inflation rate is reasonable and accordingly proposes to consider DIAL’s submission.

9.2.31 The Aeronautical portion of Rent expenses submitted by DIAL and proposed to be considered by the

Authority for the Fourth Control Period is as follows:

Table 249: Aeronautical Rent Expenses submitted by DIAL and proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Total (Rs.

9.2.32 The Authority analysed DIAL’s submission wherein Rates & Taxes are escalated at the rate of inflation for the Fourth Control Period with FY 2024 as the base.

9.2.33 Rates & Taxes majorly pertain to the operating license fee of Trunk Mobile Radio Service (TMRS) and is paid to Department of Telecommunication (DOT). These equipment are used by various stakeholders like ARFF, CISF, AOCC, Airside Personnel, Airlines etc. for operational purposes. It may be noted that the operating license fee is determined by the DOT. Rates and Taxes also include Stamp Duty charges for agreements entered by DIAL with various parties and expenses towards Delhi Pollution Control Committee.

9.2.34 The Authority based on its analysis noted that the past growth rates (annual as well as CAGR for five year period) of Rates & Taxes were highly inconsistent on account of the nature of these items.

9.2.35 The Authority is of the view that DIAL’s projection of Aeronautical Rates & Taxes based on inflation rate is reasonable and accordingly proposes to consider DIAL’s submission.

9.2.36 The Aeronautical portion of Rates & Taxes submitted by DIAL and proposed to be considered by the

Authority for the Fourth Control Period is as follows:

Table 250: Aeronautical Rates and Taxes submitted by DIAL and proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Total (Rs.

9.2.37 The Authority analysed DIAL’s submission regarding Professional and Consultancy expenses which are projected at inflation rate of 4.6% p.a. as well as real growth of 10% p.a. for the Fourth Control Period i.e. an effective annual growth rate of 15% p.a.

9.2.38 Professional and Consultancy expenses are towards various services availed from the external parties viz. Technical Services from Consultants, Retainer Fee various expertise personnel, Placement Fee / Fee for recruitments, Audit Services such as Tax Audit, Internal Audit, Secretarial Audit etc, Training Fee paid to various consultants, Legal Expenses and Outsourcing Expenses.

9.2.39 The Authority examined the break-up of Professional and Consultancy expenses for FY 2024 which forms the basis for projections for the Fourth Control Period. The break-up is as follows:

Table 251: Break up of Professional & Consultancy Charges for FY 2024 considered as base S. No Particulars Amount (Rs. Cr) Remarks Includes consultancy charges for various 1 Consultancy charges 25.07 initiatives, strategic planning, advisory fees etc.

Consultation Paper No: 07/ 2024-25 Page 240 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD S. No Particulars Amount (Rs. Cr) Remarks Consultancy charges – Retainer consultants hired for business 2 14.32 HR continuity.

Consultancy charges – Consultancy charges towards finance, audit 5 Finance, Audit and 2.66 and technical related services.

Technical Total 66.64

9.2.40 The Authority noted that consultancy charges towards legal consultants constituted significant portion

of Professional and Consultancy expenses for the Third Control Period as mentioned below:

Table 252: Legal charges & percentage in Professional & Consultancy charges FY ending March 31 (Rs. Cr) 2020 2021 2022 2023 2024 Total Consultancy charges – Legal (A) 16.74 22.07 16.31 40.14 13.70 108.95 Professional and Consultancy expenses (B) 99.08 62.28 67.96 104.45 66.64 400.40 % of Professional and Consultancy expenses

16.90% 35.44% 24.00% 38.43% 20.55% 27.21% (A/B)

9.2.41 The above legal charges paid by DIAL are not at all critical or necessary for the Aeronautical Operations of the Airport and are by nature paid towards legal cases with other stakeholders. As these don’t have any value addition to the services offered to the airport users, the Authority proposes to disallow these expenses as part of Professional and Consultancy expenses for the Fourth Control Period. The Authority also noted that even in the concession agreements executed by GoI for recent airports, legal expenses are excluded from the O&M expenses considered as a passthrough for tariff determination.

9.2.42 The Authority analysed the past growth rates of Professional and Consultancy expenses and noted that the annual growth rates as well as CAGR for five and ten-year periods are highly inconsistent with some of the years recording negative growth rates.

9.2.43 Considering the above, the Authority proposes to consider only the inflation rate of 4.6% p.a. for projecting Professional and Consultancy expenses for the Fourth Control Period and also proposes not to consider Legal expenses for the Fourth Control Period.

9.2.44 The Aeronautical portion of Professional and Consultancy expenses excluding legal charges proposed to be considered by the Authority for FY 2024 is Rs. 41.71 Cr as per Table 100. The same is taken as the base for projections for the Fourth Control Period.

9.2.45 The Aeronautical portion of Professional and Consultancy expenses submitted by DIAL and proposed

to be considered by the Authority for the Fourth Control Period is as follows:

Table 253: Aeronautical Professional & Consultancy expenses submitted by DIAL and proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Total (Rs. Cr) Aero portion of 61.44 70.70 81.34 93.59 107.69 414.76

43.63 45.64 47.74 49.94 52.23 239.18 proposed to be considered by the Authority Printing and Stationery Expenses

9.2.46 The Authority analysed DIAL’s submission regarding Printing and Stationery expenses for the Fourth Control Period wherein the expenses are escalated at the inflation rate of 4.6% p.a. In addition to this, DIAL has considered one-time increase of 51.52% and 10% in FY 2025 and FY 2028 respectively on account of increase in passenger handling capacity.

9.2.47 The Authority noted that the past growth rates under this head are inconsistent with negative growth rates in some of the years.

9.2.48 The Authority also noted that the Printing and Stationery expenses are not correlated to the traffic growth. Hence, the Authority is of the view that DIAL’s submission of correlating these expenses to growth in passenger handling capacity is not correct. Accordingly, the Authority proposes to consider only inflation rate of 4.6% p.a. for projecting Printing and Stationery expenses for the Fourth Control Period.

9.2.49 The Aeronautical portion of Printing and Stationery expenses submitted by DIAL and proposed to be

considered by the Authority for the Fourth Control Period is as follows:

Table 254: Aeronautical Printing and Stationery expenses submitted by DIAL and proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Total (Rs.

9.2.50 The Authority analysed DIAL’s submission regarding Travelling and Conveyance expenses for the Fourth Control Period which has been escalated at inflation rate of 4.6% p.a. In addition to this, DIAL has considered manpower escalation factor of 20.61% and 4% in FY 2025 and FY 2028 respectively on account of increase in passenger handling capacity at the Airport.

Consultation Paper No: 07/ 2024-25 Page 242 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD

9.2.51 Travelling and Conveyance expenses comprise expenses pertaining to Local Conveyance, Travel Charges for the employees (Domestic / Foreign) and Chartering Costs for senior management of DIAL.

The break-up of the expenses for FY 2024 are as follows:

Table 255: Travelling & Conveyance expenses for FY 2024 S. No Particulars Amount (Rs. Cr) Remarks 1 Chartering Cost 27.61 Business related travel by senior management 2 Vehicle Hire Charges 8.50 Vehicle hired for the operations of the Airport 3 Foreign Travel Fare 3.98 Employee foreign travel air fare charges Foreign Travel – Other Employee foreign travel lodging and 4 3.57 Expenses boarding expenses 5 Inland Travel Fare 2.29 Employee inland travel fare charges Local Conveyance – 6 1.21 Taxi hire charges for the staff of the Airport Taxi Hire Inland Travel – Other 7 1.00 Employee inland travel lodging and boarding Expenses Miscellaneous expenses towards employee 8 Others 0.57 travel Total 48.74

9.2.52 The Authority sought clarification on the nature of Chartering Costs and its essentiality/ relevance to the Airport operations. DIAL clarified that its senior management is eligible for charter flights for business travel mainly for the purpose of meetings, seminars, marketing & business development.

Further, DIAL has entered into an agreement with Indo Pacific Aviation Private Limited for availing charter services where fixed payment towards utilization of services has been agreed upon.

9.2.53 The Authority proposes to project Travelling and Conveyance expenses based on inflation rate of 4.6% p.a. along with adjusted manpower escalation factor of 14.53% and 4% in FY 2025 and FY 2028 respectively. The Authority consistent with the view taken for true up of the O&M Expenses for the Third Control Period has proposed to consider only 50% of the Chartering Costs as the base for applying the growth rates as mentioned above.

9.2.54 The Aeronautical portion of Travelling and Conveyance expenses submitted by DIAL and proposed to

be considered by the Authority for the Fourth Control Period is as follows:

Table 256: Aeronautical Travelling and Conveyance expenses submitted by DIAL and proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 2025 2026 2027 2028 2029 Total (Rs. Cr) Aero portion of Travelling and

Consultation Paper No: 07/ 2024-25 Page 243 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD Communication Costs

9.2.55 The Authority analysed DIAL’s submission regarding Communication Costs for the Fourth Control Period which has been projected based on the inflation rate of 4.6% p.a. In addition to this, DIAL has considered one-time increase of 51.52% and 10% in FY 2025 and FY 2028 respectively attributed to increase in passenger handling capacity of the Airport.

9.2.56 Communication costs include the Leased Line Charges/VPN for administration purposes across the airport, mobile expenses for its employees. These costs are non-recoverable from any of the concessionaires.

9.2.57 The Authority proposes to consider only inflation rate of 4.6% p.a. for projecting Communication costs for the Fourth Control Period.

9.2.58 The Aeronautical portion of Communication Costs submitted by DIAL and proposed to be considered

by the Authority for the Fourth Control Period is as follows:

Table 257: Aeronautical Communication Costs submitted by DIAL and proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 (Rs. Cr) 2025 2026 2027 2028 2029 Total Aero portion of Communication Costs

2.23 2.34 2.44 2.56 2.67 12.25 proposed to be considered Advertising and Sales Promotion

9.2.59 The Authority analysed DIAL’s submission regarding Advertising and Sales Promotion for the Fourth Control Period which has been projected based on inflation rate of 4.6% p.a. as well as passenger traffic growth i.e. an effective increase ranging between 9% and 11%. It may be noted that DIAL has considered expenses pertaining to FY 2023 as the base for projecting expenses for FY 2025 as the expenses pertaining to FY 2024 were unusually high.

9.2.60 The Authority sought clarifications from DIAL on the unusually high expenses incurred in FY 2024.

DIAL submitted that during FY 2024, it had incrementally spent on many new events related to G20, customer engagement activities, manpower contract for supporting Digi yatra, campaigns for Skytrax on social media platform, providing transportation services during departure and arrival phase of HAJ operations to HAJ pilgrims and various sponsorships for events etc. All these led to one time increase in Advertisement expenses compared to FY 2023. To avoid aberration, DIAL considered expenses pertaining to FY 2023 for projecting expenses for FY 2024.

9.2.61 DIAL also submitted that in order to protect the interest of the Airport considering the competition from the upcoming Noida International Airport, DIAL projected to incur expenditure for attracting the passengers by way of various advertisements highlighting passenger experience, facilities, service quality and ratings of the Airport. Thus, DIAL has projected Advertising expenditure based on passenger traffic growth and inflation.

9.2.62 The Authority analysed the past growth rates and noted that the same is highly inconsistent and this expense in the past has been independent of passenger traffic growth.

9.2.63 Further, the Authority also noted that the advertising and sales promotion expenses are expected to increase in line with the increase in terminal area rather than passenger traffic growth. Accordingly, the Authority proposes to escalate Advertising and Sales Promotion expenses based on inflation along

Consultation Paper No: 07/ 2024-25 Page 244 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD with adjusted terminal area expansion factor of 14.53% and 4.54% in FY 2025 and FY 2028 respectively.

11.70 12.23 12.80 13.99 14.64 65.36 proposed to be considered by the Authority Corporate Costs

9.2.65 The Authority analysed DIAL's submissions regarding allocation of Corporate costs for the Fourth Control Period wherein costs are projected based on inflation (4.6%), growth in manpower cost (7%) and manpower escalation factor (20.61% and 4% in FY 2025 and FY 2028 respectively) i.e. an effective growth of 12% p.a. excluding manpower escalation factor.

i. Corporate costs pertain to allocations of cost of services provided by GMR Airports Limited (GAL, shareholder of DIAL) and GMR Airports Infrastructure Limited (GAIL, holding company of GMR Airports Limited) to DIAL.

ii. Both GAL and GAIL have corporate departments which support their airport companies/ SPVs and charge them for use of resources involved in carrying out these activities. The allocation of costs is based on the report submitted by Deloitte Touche Tohmatsu Private Limited in 2022 which contains cost drivers for allocation of cost incurred by the group companies for specific services provided to DIAL. As per the report, cost drivers have been identified for each of the departments (or a group of similar departments).

iii. The weighted average of asset size of business is considered as the cost driver for allocation of costs incurred by GAL while the primary cost drivers for allocation costs incurred by GAIL are number of employees and asset size.

9.2.66 The Authority analysed the past growth rates pertaining to Corporate Costs and noted that the same is highly inconsistent.

9.2.67 The Authority is also of the view that the rates considered by DIAL for projecting Corporate Costs are higher. The Authority noted that the services provided by group entities mentioned above are primarily related to HR and Corporate Finance i.e. manpower related functions.

9.2.68 Accordingly, the Authority proposes to consider growth rate of 6% p.a. for projecting Corporate Costs along with manpower growth factor of 14.53% and 4.00% in FY 2025 and FY 2028 respectively for

9.2.88 The Authority analysed DIAL’s submission regarding Repairs and Maintenance expenses (Building, Plant & Machinery, IT and Others) which have been projected considering inflation rate of 4.6% p.a.

along with terminal area expansion factor of 21.79% and 6.81% in FY 2025 and FY 2028 respectively.

9.2.89 The Authority sought clarifications from DIAL on the details and justifications for projection of Repairs and Maintenance expenses for the Fourth Control Period. DIAL’s responses are as follows:

• Plant & Machinery: DIAL has deployed state-of-the-art machinery & equipment for smooth and safe functioning of the Airport in the form of Baggage Handling Systems, Travelators & Escalators, X-Ray Machines, Fire Tenders, Air Ground Lighting Systems, HVAC & associate Equipment, Electrical Installations (including MRSS) and other miscellaneous equipment for operations. These equipments require regular maintenance and upkeep to perform at the desired output for safe, productive and Aeronautical operations. DIAL has entered into various Annual Maintenance Contract/ Comprehensive Maintenance Contracts (AMC/CMC) with Original Equipment Manufacturers (OEMs) for maintenance of these equipment across the Airport. DIAL has considered inflation as well as increase in scale of operations (Terminal Area) as it entails to the enhanced deployment of machinery & equipment and their respective maintenance costs.

• Buildings: The costs are associated with the need-based refurbishment or maintenance works for buildings. • Information Technology (IT): This pertains to Enterprise IT services. DIAL has multiple service level agreements with various parties for providing the services of SAP (ERP maintained by DIAL), Office 365 (infra for webmail, office applications), management of data centres, IT support for the employees, AMC/CMC of the IT Equipment and servers etc.

• Runways, Taxiway & Internal Roads: The costs are associated with the need-based refurbishment or maintenance works for runways, taxiway and internal roads of IGIA.

9.2.90 The Authority also analysed the past growth rates of Repairs and Maintenance expenses to understand the past trend. The past CAGR of various heads under Repairs and Maintenance expenses was highly inconsistent.

9.2.91 The Authority after analysing the past growth rates and the justifications provided by DIAL proposes to project Repairs and Maintenance expenses for the Fourth Control Period based on escalation at inflation rate of 4.6% p.a. along with consideration of adjusted terminal area expansion factor of

14.53% and 4.54% in FY 2025 and FY 2028 respectively.

(lease payment of Rs. 7.20 Cr for 84 months on cost of Rs. 400 Cr) which is higher while compared with the effective cost of debt of 10.55% claimed by DIAL for the Third Control Period. Further, the Authority noted that DIAL has not considered interest income on the security deposits which needs to be netted off against the lease payments.

9.2.111 Accordingly, the Authority proposes to consider lease payments at the Aeronautical Cost of Debt proposed to be considered by the Authority for the Third Control Period i.e. 10.37% p.a. The lease payment at an interest rate of 10.37% p.a. works out to Rs. 6.72 Cr per month and interest income on security deposits works out to Rs. 7 Cr per annum.

9.2.112 Further, since the finance lease payment to equipment related to Aeronautical operations, the Authority proposes to consider the entire lease payments as aeronautical as considered by DIAL.

9.2.113 The finance lease payments proposed to be considered by the Authority for the Fourth Control Period

is tabulated below:

Utility Expenses:

9.2.115 The Authority analysed the submission made by DIAL with regards to Utility expenses. DIAL has escalated the cost of Utilities viz. Power and Water at inflation rate (4.6%) as well as terminal area expansion factor of 21.79% and 6.81% in FY 2025 and FY 2028 respectively.

9.2.116 The Authority noted DIAL’s submission that IGIA’s terminal area is projected to increase by 22% and passenger handling capacity by 52%. The cost of utilities is directly proportional to increase in terminal area. DIAL has submitted that the power and water demand at IGIA is expected to rise due to increase in passenger traffic and terminal area expansion.

9.2.117 The Authority noted that DIAL has tied-up with GMR Bajoli Holi Hydropower for procurement of power till FY 2036. Of total capacity of 180 MW, 120 MW from the power plant is allotted to DIAL.

The Authority noted that PPA provides for annual energy requirement of DIAL till FY 2036.

9.2.118 The all-inclusive landed rate of power stood at Rs. 9.62/unit in FY 2024 which includes PPA tariff of Rs. 6.51/unit and other charges (transmission charges, transmission losses, wheeling charges, SLDC charges etc.) of Rs. 3.11/unit. Capacity of in-house solar plant is 8 MW which met only 4% of total power consumed in FY 2024.

9.2.119 The Authority noted that DIAL also procures power from Delhi Discom (BSES Rajdhani Power Ltd – BRPL) in case of any shortfall. However, the Authority noted that the landed rate of power sourced from BRPL in the last three FYs i.e. FY 2022, FY 2023 and FY 2024 was above Rs. 13/unit.

Accordingly, the Authority is of the view that average rate of power procured from GMR Bajoli Holi is considerably lower than that of power procured from BRPL. Hence the Authority is also of the view that the arrangement for power procurement through the PPA is efficient.

9.2.120 The Authority analyzed the past trend in utility consumption by IGIA and the analysis is presented

below:

Table 276: Utility consumption by DIAL in the Third Control Period 4-Year FY ending March 31 2020 2021 2022 2023 2024 Total CAGR Electricity Electricity Consumption (MU) 236.68 162.71 200.92 237.62 253.97 Average Rate (Rs/kWh) 8.88 8.80 9.44 10.18 10.01 3.02% Gross Charges (Rs.

Cr) 2.35 -1.03 -3.37 1.11 2.36 1.42

9.2.121 The Authority proposes to consider an increase in the projected Power and Water consumption in the Fourth Control Period based on the adjusted terminal area expansion factor of 14.53% and 4.54% in FY 2025 and FY 2028 respectively. The Authority also proposes to escalate the average rate of Power and Water rates based on 5-year CAGR of 3.02% and 4.28% respectively.

9.2.122 Further, the Authority proposes to consider recovery% of 72% and 95% for Power and Water charges respectively based on the average recovery% of FY 2023 and FY 2024.

9.2.123 The Authority proposes to consider the net utility expenses as entirely aeronautical as the same is net of recovery from sub-concessionaires as considered by DIAL.

9.2.124 Based on the above, the Authority recalculated the Net Utility expenses for the Fourth Control Period

as tabulated below:

9.2.126 The Authority noted the relevant provisions of OMDA related to Airport Operator as follows: “2.5 JVC Ownership Structure

Consultation Paper No: 07/ 2024-25 Page 256 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD

(j) The Parties hereby agree and JVC shall accordingly procure that the Operator shall remain the operator in relation to the Airport for the term of this Agreement. Provided that the Operator may be changed with the prior consent of AAI after the expiry of a period of seven

Provided however that in the event the AAI does not approve of the Proposal, then the JVC shall propose another Entity as the Alternate Operator, and the procedure mentioned in this subclause (k) shall be repeated until a Proposal is approved by AAI. It is clarified that until such time as an Alternate Operator meeting the approval of AAI is not found by the JVC, the JVC shall cause the Operator to continue as the operator under the Airport Operator Agreement.”

9.2.127 The Authority noted the relevant provisions of OMDA related to Share Transfer as follows: “2.5 JVC Ownership Structure

(a) The Parties hereto agree that the Prime Members of the JVC shall not transfer, create any Encumbrance or deal with any equity shares in the JVC held by them for the duration of five (5) years from the Effective Date. Provided however that the Prime Members may transfer the shares held by them to a Financial Investor, subject to the relevant Prime Member(s) continuing to

Consultation Paper No: 07/ 2024-25 Page 257 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD hold at least 10% of the issued and paid-up equity share capital in the JVC and the Prime Members (collectively, as a group) continuing to hold at least 26% of the issued and paid-up equity share capital in the JVC after any such transfer to any such Financial Investor at any time during such aforesaid period. Provided further, that a Prime member who has a corresponding Evaluated Entity, shall not transfer its shares in the JVC to a Financial Investor, resulting in dilution of the Beneficial Ownership of the Evaluated Entity in the JVC to below 10% and the sum of the Beneficial Ownership in the JVC of all Evaluated Entities and direct shareholding of the Prime Members (who have no corresponding Evaluated Entity, and whose own qualifications have been considered for the purpose of evaluation during the competitive bidding procedure undertaken by AAI for the purpose of selection of the Consortium Members for the JVC) in the JVC collectively to below 26% of the issued and paid-up equity share capital in the JVC.

Provided still further that in the event any equity shares (the “Transfer Shares”) in the JVC are so transferred to any Financial Investor (the “Transferee Financial Investor”) by any Prime Member(s) (the “Transferring Prime Member”), the Transferring Prime Member(s) and the JVC shall procure that such Transferee Financial Investor shall not, for a duration of five (5) years from the Effective Date, transfer the whole or any portion of the Transfer Shares to any Entity other than another Financial Investor, who in turn (and purchasers of the whole and any portion of Transfer Shares from him) shall be bound by a similar restriction. It is clarified that Financial Investor(s) who become shareholders in the JVC pursuant to this Article 2.5(a) shall not, for a duration of five (5) years from the Effective Date, transfer the whole or any portion of the Transfer Shares to any Entity other than another Financial Investor.

(b) During the period commencing from the beginning of the 6th year and ending at the end of the 7th year from the Effective Date the Prime Members may transfer, create any Encumbrance or deal with any shares in the JVC held by them, provided however that notwithstanding any such transfer, or creation of any such Encumbrance or any such dealing, the relevant Prime Member continues to hold at least 10% of the issued and paid-up share capital in the JVC and the Prime Members (collectively, as a group) continue to hold 26% of the issued and paid-up share capital in the JVC subsequent to any such transfer. Provided further, that a Prime member who has a corresponding Evaluated Entity, shall not transfer, create any Encumbrance or deal with any shares in the JVC, resulting in dilution of the Beneficial Ownership of the Evaluated Entity in the JVC to below 10% and the sum of the Beneficial Ownership in the JVC of all Evaluated Entities and direct shareholding of the Prime Members (who have no corresponding Evaluated Entity, and whose own qualifications have been considered for the purpose of evaluation during the competitive bidding procedure undertaken by AAI for the purpose of selection of the Consortium Members for the JVC) in the JVC collectively to below 26% of the issued and paid-up share capital in the JVC.

(c) After the expiry of seven (7) years from the Effective Date, the Prime Members may, without the approval of the AAI, transfer, create any Encumbrance or deal with any shares in the JVC held by them, provided however that notwithstanding any such transfer, or creation of any such encumbrance or any such dealing, the relevant Prime Member continues to hold at least 10% of the issued and paid-up share capital in the JVC and the Prime Members (collectively, as a group) continue to hold 26% of the issued and paid-up share capital in the JVC subsequent to any such transfer. Provided further, that a Prime member who has a corresponding Evaluated Entity, may transfer, create any Encumbrance or deal with any shares in the JVC, provided that such transfer, creation of Encumbrance or dealing does not result in dilution of the Beneficial Ownership of the Evaluated Entity in the JVC to below 10% and the sum of the Beneficial Ownership in the JVC of all Evaluated Entities and direct shareholding of the Prime Members (who have no corresponding Evaluated Entity, and whose own qualifications have been considered for the purpose of evaluation

After the expiry of seven (7) years from Effective Date, shares of the JVC held by any Prime Member (or its transferee shareholder or their subsequent transferee shareholder(s)) shall not be transferred to any Entity (other than transfer permitted under the preceding sentences of this Article 2.5(c)), save with the prior written permission of the AAI, which permission shall be given unless AAI reasonably believes that the technical, financial or operational capability of the JVC pursuant to such transfer of shares (and consequent exit of the said Prime Member (or its transferee shareholder or their subsequent transferee shareholder(s)) would be inferior than prior to such transfer; save that if not approved or disapproved within 30 days it is deemed to have been approved.”

9.2.128 The Authority observed that, as per the OMDA, the Airport Operator may now be changed with the prior consent of AAI and subject to the approval of GOI as the minimum timeline of 7 years from the Effective Date has been complied. Further, the OMDA allows and provides for ways for the Operator to be replaced either by itself (DIAL) or an alternate Operator provided it satisfies the requirement of the Alternate Operator.

9.2.129 Considering the provisions of OMDA related to Airport Operator and Ownership Structure, the Authority sought clarifications from DIAL on 6th January 2025 on the following: • Impact of acquisition of Fraport AG’s equity stake in DIAL by GMR Airports Limited (GAL) on the Airport Operator agreement executed with Fraport AG for IGIA.

• Need for continuation of an external Airport Operator considering the vast experience of DIAL and GAL in managing and operating the airports. • Possibility of DIAL replacing itself as the Airport Operator as allowed under the OMDA.

9.2.130 The responses received from DIAL on the impact of acquisition of Fraport AG’s equity stake in DIAL

by GAL on the Airport Operator agreement are as follows: • During the bid stage, it was a mandatory requirement for the Prospective Bidder to be an Airport Operator or have at least one Airport Operator in its Consortium for the purpose of getting qualified.

• Bid Documents also required Airport Operator to enter a service performance contract acceptable to AAI. • Bid documents had defined entities comprising the Consortium Bidder that proposed to hold equity of 10% or more in JVC as “Prime Member”. Also, the Prime Member whose qualifications had been attributed for the purpose of evaluation was designated as “Evaluated Entity”.

• On account of the above provisions of Bidding, Fraport AG Frankfurt Airport Services Worldwide (“Fraport AG”) joined the consortium led by GMR Group for bidding for IGIA and to provide airport operator services to the JVC (DIAL), on consortium being declared successful bidder.

• Fraport AG also participated in 10% equity shareholding of the JVC. • Fraport AG is designated as both “Prime Member” as well as “Evaluated Entity” under the OMDA. • Some of the provisions of OMDA related to Airport Operator are as follows:

o DIAL to procure that Operator shall remain the operator of the Airport for the term of OMDA. o Operator may be changed or DIAL may itself become Operator with the prior consent of AAI, after the expiry of 7 years from Effective Date.

Consultation Paper No: 07/ 2024-25 Page 259 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD o AAI to evaluate the proposal of Alternate Operator based on various considerations listed under the OMDA.

• Some of the provisions of OMDA related to Share Transfer by Prime Member are as follows: o Prime Members not to transfer equity shares for a duration of 5 years from Effective Date. o Between 5th – 7th year, Prime Members can transfer their equity shares provided that Prime Member continues to hold at least 10% equity share and collectively all Prime Members continue to hold 26% equity share of DIAL.

o Post 7th year, Prime Members can transfer their entire equity shares with prior written permission of AAI. • The provisions of OMDA related to Airport Operator has no correlation with the shareholding structure of DIAL.

• Accordingly, Fraport AG continues to be the Operator under the Airport Operator Agreement and no cause has arisen for DIAL to replace it with an Alternate Operator, meeting the approval criteria of AAI.

• In case Fraport intends to divest its shareholding in DIAL, it does not make it obligatory for Fraport to also cease as an Airport Operator.

9.2.131 The responses received from DIAL on the need for continuation of Fraport as Airport Operator are as

follows: • IGIA is India’s busiest Airport operating with four runways, requiring operations even under low visibility period in winter with CAT III B needs. • Out of four runways, one runway is used by defence forces (which cannot be used with independent parallel arrival and departure movements), which also needs to be operated for VIP movements including heads of various countries.

• IGIA is operating one runway which is operated with threshold of 1,462 mtrs and due to presence of Lord Shiva statue which exceeded permitted height by 11 mtrs, DIAL needs to operate with all technical expertise.

• GOI aims to make aviation hubs in India and IGIA has been identified as the first International Hub for which active engagement with all stakeholders is required. Fraport’s experience of being one of the major international hubs will provide valuable learnings from their own experience in achieving this target.

• The upcoming Noida International Airport, which is owned by Zurich Airport AG (one of the major players in Europe), is expected to become operational in FY 25-26 and will be in direct competition with IGIA. The new entrant in the market will create new challenges through technological advancements at Airside for IGIA which will require support from Fraport (one of the major players in Europe) who can share their experience and can guide DIAL during these challenging times.

• Considering the above, having a strategic and operational expertise from international player like Fraport in the form of Airport Operator will be a crucial differentiating factor that will be critical for the growth and success of IGIA in the coming times.

• In such a dynamic and challenging environment, DIAL will continue to rely on external consultants and advisors to upgrade its operational competency to handle the new and upcoming challenges. • It may also be perused that neither Fraport has expressed its intention nor there has been any cause for DIAL to replace Fraport as the Airport Operator. Hence, Fraport continues to be the Airport Operator under the Airport Operator Agreement.

9.2.132 Based on the provisions of OMDA related to Airport Operator and Share Transfer and the clarifications received from DIAL, the Authority also noted that Fraport AG can continue as Airport Operator even

Consultation Paper No: 07/ 2024-25 Page 260 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD after stake sale until any replacement is approved by AAI. Share transfer by Fraport AG as permitted under OMDA is independent of the Airport Operator Agreement.

9.2.133 The Authority noted the responses/ clarifications received from DIAL on the need for continuation of Fraport as Airport Operator of IGIA.

9.2.134 Accordingly, the Authority consistent with its proposal to calculate Airport Operator Fee as 3% of the Aeronautical Revenues of the previous year for the past Control Periods proposes to consider the Airport Operator Fee as 3% of the projected Aeronautical Revenues for the Fourth Control Period which has been revised based on various regulatory building blocks for arriving at Target Revenue as per the current tariff determination exercise. The same would be trued up based on actuals at the time of tariff determination for the Fifth Control Period.

9.2.135 The Airport Operator Fee as submitted by DIAL and the Airport Operator Fee proposed to be

considered by the Authority is shown in the table below:

Forex Fluctuation

9.2.136 The forex fluctuations submitted by DIAL for the Fourth Control Period is as follows:

Table 280: Forex Fluctuations submitted by DIAL for the Fourth Control Period FY ending March 31 (Rs. Cr) 2025 2026 2027 2028 2029 Total Forex Fluctuations submitted by DIAL 50.93 50.99 41.46 32.26 32.34 207.98

9.2.137 The Authority has analysed the submissions of DIAL and is of the view that the effective cost of funds finally utilized by DIAL towards capex activities in the Fourth Control Period could be analysed only at the time of true up and, based on the same, would consider admitting certain forex losses incurred at actuals provided that the effective cost of debt doesn’t exceed the efficient cost of debt considered as per the Tariff Order for the Fourth Control Period.

Property Tax

9.2.138 The Authority has analysed DIAL’s submissions regarding Property Tax for the Fourth Control Period.

DIAL submitted that property tax outflows have been projected based on the settled principles for the

Consultation Paper No: 07/ 2024-25 Page 261 of 292AERONAUTICAL OPERATION AND MAINTENANCE EXPENSES FOR THE FOURTH CONTROL PERIOD assessment of the property tax by the area covered by South Delhi Municipal Corporation (SDMC) and Delhi Cantonment Board (DCB).

9.2.139 With regard to SDMC, DIAL paid property tax of Rs. 34.79 Cr in FY 2024. Accordingly, DIAL has considered property tax outflow of Rs. 34.79 Cr throughout the Fourth Control Period.

9.2.140 With regard to DCB, DIAL expects property tax demand of Rs. 10.94 Cr for FY 2024 based on the methodology in the Delhi High Court order. As per DIAL, property tax pertaining to DCB is variable and calculated based on the revenue generated from Terminal 1. DIAL has considered property tax outflow of Rs. 22.59 Cr for FY 2025 and the same is escalated at 7.5% p.a. till FY 2029. The total

property tax payments submitted by DIAL for the Fourth Control Period is tabulated below:

Table 281: Property tax submitted by DIAL for the Fourth Control Period FY ending March 31 (Rs. Cr) 2025 2026 2027 2028 2029 Total SDMC 34.79 34.79 34.79 34.79 34.79 173.95 DCB 22.59 24.29 26.11 28.07 30.17 131.23 Pending Dues of DCB paid/to be paid 52.62* 52.62 Total Property Tax 110.00 59.08 60.90 62.86 64.96 357.80 *DIAL paid Rs. 41.68 Cr against assessment order from DCB dated April 18, 2024 towards property tax pertaining from FY 2007 to FY 2016. Expected property tax of Rs. 10.94 Cr for FY 2024 is also considered.

9.2.141 The Authority after analysing the matter proposes to consider DIAL’s projection of property tax for SDMC for the Fourth Control Period. With regard to DCB, the Authority proposes to consider property tax estimate of Rs. 22.59 Cr in FY 2025 as the increase is justifiable considering that the area of Terminal 1 has more than doubled after Phase 3A Expansion. However, the Authority proposes to consider inflation rate of 4.6% p.a. for escalation of property tax pertaining to DCB from FY 2026 onwards.

9.2.142 The Authority also proposes to allocate property tax into Aero and Non-aero based on the proportion of Aero portion of O&M expenses (excluding property tax and Airport Operator Fee) to the total O&M expenses (after excluding disallowed expenses like Bad Debts, Donation, CSR and Forex) in the respective years of the Fourth Control Period.

10. REVENUE FROM REVENUE SHARE ASSETS FOR THE FOURTH CONTROL PERIOD

10.1 DIAL’s Submissions regarding Revenue from Revenue Share Assets for the Fourth Control Period

10.1.1 DIAL has computed Revenue from Revenue Share Assets for the Fourth Control Period by considering fully operational terminals and taking into account non-aeronautical streams like Air traffic related revenue, Passenger related revenue, Contract linked revenue and revenue from Cargo operations.

10.1.2 DIAL has also considered inflation rate of 4.60% p.a. for projecting Revenue from Revenue Share Assets under certain heads for the Fourth Control Period.

10.1.3 The basis adopted by DIAL for projecting non-aeronautical revenue is as follows:

Air Traffic (ATM) Related Revenue:

Ground Handling

10.1.4 The revenue that accrues to DIAL from Ground Handling – Registered Parties is proportional to the growth in international ATMs. Hence, DIAL has considered the revenue growth linked to the growth of International ATMs. Further, DIAL has projected the tariff of Ground Handlers to increase by 5% in FY 2026 and FY 2029.

10.1.5 There is a decrease in the third-party Ground Handling revenue for DIAL due to implementation of the Ground Handling rules in 2018. Major airlines like Indigo, SpiceJet, Vistara carryout Self handling and therefore DIAL doesn’t foresee any increase in the revenue share from third party Ground Handling.

However, DIAL has considered inflationary growth of 4.6% for every year on the base year revenue of FY 2023-24.

Bridge Mounted Equipment (BME)

10.1.6 The revenue accrued to DIAL is directly proportional to the growth of the ATMs. Thus, DIAL has considered the growth of overall ATM for projection of revenue from Bridge Mounted Equipment.

Passenger Related Revenue:

Inflight Kitchen (IFK)

10.1.7 DIAL in its submission has calculated revenue for IFK for all the years in the Fourth Control Period by considering revenue from IFK for FY 2024 as base and has applied growth factor of overall passenger traffic growth rate. In addition to the overall passenger traffic growth rate an inflationary increase of 5% is considered in FY 2026 and FY 2029 for the prices charged by IFK.

Multilevel Car Parking

10.1.8 In accordance with the contract, price revision is allowed to the MLCP concessionaire once in every 3 years. Consequently, DIAL has considered overall passenger traffic growth rate as well as 5% increase in the tariffs of MLCP in FY 2026 and FY 2029 for projection of the said revenue by considering revenue from FY 2024 as base.

Radio Taxi

10.1.9 As the connectivity of metro across all terminals have improved, the passengers prefer to travel through metro. In view of the availability of cab aggregators such as Ola, Uber and Blu, DIAL is foreseeing de-

Consultation Paper No: 07/ 2024-25 Page 264 of 292REVENUE FROM REVENUE SHARE ASSETS FOR THE FOURTH CONTROL PERIOD growth in the earnings from Radio Taxi. However, for the purpose of projection DIAL has considered the base year revenue in FY 2024 for all the projected years.

Food & Beverages, Retail Duty Paid and Lounge income

10.1.10 The revenues accrued to DIAL from F&B, Retail and Lounge concessionaries are directly linked to the passenger spend. Hence, DIAL has considered revenue from Food & Beverage, Retail Duty & Lounge income of FY 2024 as the base and has applied passenger traffic growth rate as well as inflationary growth for projecting the revenue for the future periods.

Others passenger linked revenue

10.1.11 DIAL has considered the passenger traffic growth as well as inflationary growth for projecting the revenue for the future periods.

International Duty Free:

10.1.12 DIAL has considered inflationary increase of prices at 4.6% along with the international passenger traffic growth for the purpose of projections.

Contract linked revenue:

Advertisement

10.1.13 IGIA is a matured asset and has reached its maximum capacity both in terms of advertisement space and the pricing is also the highest in Delhi NCR. Further, there is an increased trend of digital advertising in comparison to the traditional hoardings and its impact. Considering this impact, DIAL has considered only inflationary increase in the prices for the purpose of projections, along with the increase in existing concession fee by 11% from the base year of FY 2025.

Forex

10.1.14 Due to increase in usage of credit card and proposed UPI for foreign nationals, DIAL is expecting a moderate growth in the Forex revenues. For the Fourth Control Period, forex revenue is expected to be increased by international passenger growth only.

Land & Space

10.1.15 DIAL has reached its saturation in land & space across all the terminals and land blocks, and hence DIAL has considered only contractual increase of 7.5% every year. However, post completion of Phase 3A, DIAL is projecting one time increase of revenue by 10% in FY 24-25 due to additional space available inside the Terminal 1 for leasing out.

Other contract linked revenue

10.1.16 Other revenue like Common Area Management (CAM), Airport Service Charges (ASC), transit hotel and telecom are expected to grow by CPI linked inflation.

Cargo Related Revenue:

10.1.17 DIAL has considered the traffic study conducted by the ICF to assess the traffic at IGI Airport.

Accordingly, DIAL requested the Authority to consider Cargo Revenue linked with the cargo traffic projection. Further, DIAL has considered inflationary increase in the rate of Cargo concession revenues by 5% in FY 2026 and FY 2029.

10.2.25 The Authority’s analysis of the Contribution per passenger towards revenue from the above-mentioned

heads over the last five years is provided below:

Table 298: Past CAGR for Contribution per Pax towards Passenger Traffic Related Revenue FY ending March 31 5-Year CAGR 2019 2020 2021 2022 2023 2024 (Contribution per Pax in Rs.)

10.2.26 The Authority noted that, as can be seen from the table above, the Y-o-Y increase in Contribution per Pax considered by DIAL in the Fourth Control Period is considerably lower than the past five-year CAGR.

10.2.27 The Authority formed the view that the past five-year growth rate should be sustainable in the Fourth Control Period. The Authority is of the view that there was no strong reason to consider any moderation in growth rate as some of these revenue items in the past had grown independent of the Pax traffic growth rate. The Authority hence proposes to consider the past five-year CAGR as the expected growth rate for the above-mentioned revenue streams in the Fourth Control Period.

Car Park (MLCP and Radio Taxi)

10.2.28 The Authority analysed DIAL’s submissions regarding revenue from Car Park i.e. MLCP and Radio Taxi. The Authority noted that the concession for MLCP is vested with Delhi Airport Parking Services Private Limited with revenue share at the rate of 40% of gross revenue (w.e.f. April 01, 2022) while the contracts for Radio Taxi is with various cab aggregators viz. Ola, Uber etc.

10.2.29 The Authority’s analysis of the Contribution per passenger towards revenue from Car Park (MLCP and Radio Taxi) for the Fourth Control Period as submitted by DIAL is provided below:

Table 299: Contribution per Pax towards revenue from Car park as submitted by DIAL for the Fourth Control Period FY ending March 31 5-Year CAGR 2025 2026 2027 2028 2029 (Contribution per Pax in Rs.) (FY 2024-29) Car Park (MLCP) 12.6 13.2 13.2 13.2 13.9 2.0% Y-o-Y Increase % 0% 5% 0% 0% 5%

10.2.30 The Authority’s analysis of the Contribution per passenger towards revenue from Car Park (MLCP and Radio Taxi) over the last five years is provided below:

Table 300: Past CAGR of Contribution per Pax towards revenue from Car Park FY ending March 31 5-Year CAGR 2019 2020 2021 2022 2023 2024 (Contribution per Pax in Rs.) (FY 2019-24) Car Park (MLCP) 4.5 5.1 8.7 8.8 11.2 12.6 23.0% Car Park (Radio Taxi) 2.7 2.5 1.6 2.0 2.7 3.2 3.3%

10.2.31 Based on the clarifications from DIAL, the Authority noted that the past 5-year CAGR of contribution per pax towards revenue from car parking (MLCP) was exceptionally high as the revenue share was increased from 20% to 40% in FY 2021. As per the contract with MLCP operator, revenue share would be increased after a gap of 3 years with the next revision due on April 01, 2025. Accordingly, for the purpose of projections, the Authority proposes to consider an increase in contribution per pax at the rate of 15% w.e.f. April 01, 2025 and April 01, 2028.

10.2.32 The Authority however noted that the Y-o-Y decrease in Contribution per Pax considered by DIAL for Car Park (Radio Taxi) is unreasonable. The Authority is of the view that there was no justifiable reason to consider any tempered/negative growth rate as these revenue items in the past, in absolute terms, had grown independent of the Pax traffic growth rate which could be seen from the considerably high growth rates in the last few years. The Authority hence proposes to consider the past five-year CAGR (3.3%) for the revenue from Car Park (Radio Taxi).

Retail

10.2.33 The Authority analysed the submissions made by DIAL regarding revenue from Retail and is of the view that the projections in the Fourth Control Period are reasonable considering the past CAGR. The Authority hence proposes to consider the projections as submitted by DIAL for revenue from Retail.

10.2.34 Based on the above, the Passenger Traffic Related revenue proposed to be considered by the Authority

for the Fourth Control Period is as follows:

10.2.39 The Authority noted that DIAL has considered a marginally lower growth rate viz-a-viz the past 5-year CAGR.

10.2.40 The Authority is of the view that the past 5-year CAGR should be the sustainable and proposes to consider the past five-year CAGR as the expected growth rate for this revenue stream in the Fourth Control Period.

10.2.41 Based on the above, the revenue from international duty-free related services proposed to be considered

by the Authority for the Fourth Control Period is as follows:

Table 305: Revenue from Duty-Free related services proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 (Rs. Cr) 2025 2026 2027 2028 2029 Total International Duty-Free Services 739.74 825.53 925.94 1,031.92 1,142.26 4,665.38 Contract-linked Revenue

10.2.44 The Authority analysed the submissions made by DIAL regarding advertisement revenue. The concession for advertisement is vested with TIM Delhi Airport Adv Private Limited with revenue share at the rate of 55% of net revenue till June 2025 and 61% of net revenue from July 2025 onwards.

10.2.45 The Authority noted that DIAL has considered only one-time increase of 10.91% on revenue in FY 2026 (to factor in the increase in revenue share from July 2025 onwards) and thereafter has been projected to be constant.

10.2.46 The Authority also noted that the terminal area has increased considerably after Phase 3A Expansion and it is expected to increase further in FY 2028 due to proposed addition of Pier E. The Authority is of the view that the advertisement revenue should increase in consistency with the increase in terminal area. Accordingly, in addition to factoring in increase in revenue share in FY 2026, the Authority also proposes to consider terminal area expansion factor as well in projecting the revenue from advertisements.

10.2.47 Based on the above, the Authority proposes to project Advertisement revenue based on one-time increase of 10.91% in FY 2026 along with adjusted terminal area expansion factor of 14.53% and

4.54% in FY 2025 and FY 2028 respectively.

Land Leases and Spaces

10.2.48 The Authority analysed DIAL’s submission regarding the revenue stream from land and spaces and noted that DIAL has considered contractual increase of 7.50% Y-o-Y and area increase factor of 10% in FY 2025.

10.2.49 The Authority also noted that the terminal area has increased considerably after Phase 3A Expansion and it is expected to increase further in FY 2028 due to construction of Pier E. The Authority formed the view that the revenue under this head is highly correlated to the increase in terminal area.

Consultation Paper No: 07/ 2024-25 Page 274 of 292REVENUE FROM REVENUE SHARE ASSETS FOR THE FOURTH CONTROL PERIOD Accordingly, in addition to factoring in contractual increase of 7.5% YoY, the Authority also proposes to consider terminal area expansion factor as well in projecting the revenue from land leases and spaces.

10.2.50 Based on the above, the Authority proposes to project revenue from land leases and spaces based on YoY increase of 7.5% along with adjusted terminal area expansion factor of 14.53% and 4.54% in FY 2025 and FY 2028 respectively.

Forex

10.2.51 The Authority analysed the submissions with respect to revenues from Forex for the Fourth Control Period. The concession for Forex is vested with Thomas Cook India Limited with revenue share varying between 6.61% and 6.70% of the revenue.

10.2.52 The Authority noted that DIAL’s projection for revenue from Forex is based on international Pax growth rate which is relatively better than past 10-yr CAGR.

10.2.53 The Authority accordingly proposes to consider the projections as submitted by DIAL for revenues from Forex for the Fourth Control Period.

Common Area Management

10.2.54 The Authority analysed the submissions with respect to revenues from Common Area Management for the Fourth Control Period and noted that DIAL has considered only the contractual increase of 7.50% for projecting revenue from Common Area Management.

10.2.55 The Authority also noted that the terminal area has increased considerably after Phase 3A Expansion and it is expected to increase further in FY 2028 due to construction of Pier E. The Authority formed the view that the revenue under this head is highly correlated to the increase in terminal area as common area is expected to increase in line with the increase in terminal area. Accordingly, in addition to factoring in contractual increase of 7.5% YoY, the Authority also proposes to consider adjusted terminal area expansion factor as well in projecting the revenue from Common Area Management.

10.2.56 Based on the above, the Authority proposes to project revenue from Common Area Management based on YoY increase of 7.5% along with adjusted terminal area expansion factor of 14.53% and 4.54% in FY 2025 and FY 2028 respectively.

Transit Hotel

10.2.57 The Authority analysed the submissions with respect to revenues from Transit Hotel for the Fourth Control Period which has been escalated at inflation rate of 4.6%. The concession for Transit Hotel is vested with Devaryaa Hospitalities with revenue share at the rate of 18% till 2025 and 20% afterwards.

10.2.58 The Authority noted that the revenue from Transit Hotel has grown at a 10-year CAGR (FY 2014-24) of 8.12%.

10.2.59 The Authority also noted that the hotel has completed around 15 years of operations and expected that the occupancy rates shall have been stabilized by now. Accordingly, any upside on the revenue shall be from the increase in rentals alone.

10.2.60 Based on the above, the Authority proposes to consider annual growth rate of 8.12% p.a. for the Fourth Control Period as against DIAL’s submission of inflation-linked growth.

Revenue from Airport Service Charges, Banks, Telecom and Others

10.2.61 The Authority noted the revenue stream from Airport Service Charges, Banks and Telecom and miscellaneous sources had been inconsistent in the past and no trend could be established. Hence, the

Consultation Paper No: 07/ 2024-25 Page 275 of 292REVENUE FROM REVENUE SHARE ASSETS FOR THE FOURTH CONTROL PERIOD Authority proposes to consider inflation rate of 4.6% p.a. for revenue from these sources in the Fourth Control Period.

Penalties

10.2.62 The Authority noted that DIAL had collected penalties from sub-concessionaires to the tune of Rs. 0.59 Crore in the Third Control Period. The penalty collected in FY 2024 was Rs. 0.22 Crore. DIAL considered similar amount for each of the years in the Fourth Control Period. Considering the uncertain nature of the item, the Authority proposes to consider the projections as submitted by DIAL for Penalties in the Fourth Control Period.

Revenue from IT JV

10.2.63 The Authority noted that DIAL awarded the concession for management of entire IT systems at IGIA to Wipro Limited. Consequently, a JV in the name of Wipro Airport IT Services Limited (WAISL) was formed to act as the concessionaire.

10.2.64 The details of the services provided by WAISL under various heads viz. Data Centre services, Application services, Network services, End User and Common services are detailed in Table 138.

10.2.65 The Authority noted that the contract is in the nature of cost contract which ensured minimum subsistence level to the service provider. As per terms of the Master Service Agreement, in case the receivables of WAISL exceed the subsistence level in the previous financial year, the concessionaire has to pay DIAL a concession fee equivalent to the excess of receivables over subsistence level.

10.2.66 The Authority analysed DIAL’s submissions regarding revenues from IT JV based on the contract with WAISL at revenue share of 9%.

10.2.67 The Authority noted that DIAL projected the revenue under this head based on overall pax growth rate since WAISL charges on per Pax basis.

10.2.68 The Authority after examination of the submissions proposes to consider the revenue under this head as submitted by DIAL for the Fourth Control Period.

10.2.69 Based on the above, the Contract-linked revenue proposed to be considered by the Authority for the

Fourth Control Period is as follows:

10.2.70 The Authority analyzed DIAL’s submissions regarding revenues from Cargo under various heads.

10.2.71 The Cargo related revenue submitted by DIAL for the Fourth Control Period is as follows:

Table 308: Cargo related Revenue submitted by DIAL for the Fourth Control Period FY ending March 31 (Rs.

10.2.72 The Authority noted that the cargo concessions are vested with Celebi Delhi Cargo Terminal and Delhi Cargo Service Center with revenue share at the rate of 36% and 24% of the gross revenue respectively.

10.2.73 The Authority’s analysis of Contribution per Ton of Cargo towards revenue from Cargo under various

heads for the Fourth Control Period as submitted by DIAL is provided below:

10.2.74 The Authority’s analysis of Contribution per Ton of Cargo towards revenue from Cargo under various

heads over the last five years is provided below:

10.2.75 The Authority noted that the growth rates in the contribution per ton of cargo projected by DIAL against these heads are considerably lower than the past five-year CAGR pertaining to the Third Control Period. However, the Authority also notes the fact that the past five-year CAGR against these heads was exceptionally high and may be difficult for DIAL to sustain especially considering the upcoming international airport in Noida which is also planned to be developed as a cargo hub.

10.2.76 Considering the above, the Authority proposes to consider annual growth rate of 10% on the contribution per ton of cargo against respective heads.

10.2.77 Based on the above and the Cargo Traffic proposed to be considered by the Authority, the Cargo related

revenue proposed to be considered by the Authority for the Fourth Control Period is as follows:

Table 311: Cargo related revenue proposed to be considered by the Authority for the Fourth Control Period FY ending March 31 (Rs. Cr) 2025 2026 2027 2028 2029 Total Cargo related revenue Export Income 28.69 32.94 37.41 42.48 48.51 190.02 Cargo Export Screening 38.97 44.74 50.82 57.70 65.90 258.13 Domestic Cargo - Screening Charges 6.36 7.13 7.98 8.90 9.84 40.21 Concession Fee - Brownfield Cargo 275.59 313.72 354.54 400.14 451.95 1,795.95 Concession Fee - Greenfield Cargo 121.92 138.79 156.85 177.03 199.95 794.54 Total 471.52 537.32 607.60 686.25 776.15 3,078.84 Other Income

10.2.78 The Authority noted that DIAL has not projected Other Income for the Fourth Control Period.

However, in the Tariff Order for the Third Control Period, it was decided to consider Other Income (dividend income, investment income, interest income etc.) earned during the Third Control Period for cross-subsidization of revenue from Revenue Share Assets at the time of true up during tariff determination of the Fourth Control Period. The Authority therefore proposes to include dividend income for cross-subsidy at the time of true up during the Fourth Control Period.

10.2.79 The Authority in the Tariff Order for the Third Control Period also decided that the Other Income earned from aeronautical services such as dividends from fuel farm JV shall be treated as aeronautical revenues.

10.2.80 The Authority noted that the average Other Income earned by DIAL in the Third Control Period works out to Rs. 227.72 Cr (after excluding dividend income from Delhi Aviation Fuel Facility Private Limited which provides fuel farm services as the same is treated as Aeronautical Revenue). The Authority accordingly proposes to consider Other Income of Rs. 227.72 Cr for FY 2025 which shall be escalated at inflation rate of 4.6% p.a. till FY 2029.

iii. JVC shall ensure that, at the completion of the implementation of Stage 2 as referred to above, the JVC achieves a rating of 3.75 in the IATA/ACI AETRA passenger survey or greater and maintains the same throughout the Term.

12.2 Authority’s Examination regarding Quality of Service for the Fourth Control Period

12.2.1 The Authority noted that DIAL has not made any submission in the MYTP regarding Quality of Service. However, based on the clarifications sought by the Authority regarding Quality of Service, DIAL submitted Airports Council International (ACI)-Airport Service Quality (ASQ) performance report from 2019 to Q3 2024.

12.2.2 The Authority noted that: i. As per section 13 (1) (d) of the AERA Act, 2008, the Authority shall “monitor the set performance standards relating to quality, continuity and reliability of service as may be specified by the Central Government or any Authority authorized by it in this behalf.” ii. As per section 13(1)(a)(ii), the Authority is required to determine the tariff for Aeronautical services taking into consideration “the service provided, its quality and other relevant factors.”

12.2.3 The Authority noted the methodology carried out by ACI for arriving at the ASQ ratings for Airports

as follows: i. ACI ASQ is a quarterly benchmarking programme measuring passenger’s satisfaction and experience about an Airport with participation from around 350-400 airports across the world. ii. The passenger experience is measured based on passenger emotions and their impact to arrive at Emotional Score.

iii. The passenger satisfaction is measured based on various service quality parameters as

mentioned below: i. Arrival at the airport (Ease of getting to the Airport, Signage to access terminal and parking facilities) ii. Check-in (Ease of finding check-in area, waiting time at check-in, courtesy and helpfulness of staff)

Consultation Paper No: 07/ 2024-25 Page 283 of 292QUALITY OF SERVICE FOR THE FOURTH CONTROL PERIOD iii. Security screening (Ease of going through security screening, waiting time at the security screening and courtesy and helpfulness of security screening staff) iv. Border/passport control (Waiting time at Border/passport control and courtesy and helpfulness of staff) v. Shopping/dining (Restaurants/bars and value for money, shops and value for money, courtesy and helpfulness of staff) vi. Gate areas (Comfort of waiting and availability of seats at gate areas) vii. Throughout the airport (Ease of finding way, availability of flight information, walking distance inside terminal, ease of making connection with other flight, courtesy and helpfulness of staff, wi-fi service quality, availability of charging stations, entertainment and leisure options, availability and cleanliness of washrooms/toilets) viii. Airport atmosphere (Health, safety, cleanliness and ambience) iv. Additional service quality parameters considered by ACI ASQ are ground transportation to/from the airport, availability of baggage carts/trolleys, efficiency of check-in staff and business/executive lounges.

v. ACI ASQ also evaluates the service quality satisfaction level through three indexes namely Ease of traveling index, Waiting time index and staff index.

12.2.4 The Authority through its independent consultant reviewed the ACI ASQ performance reports of DIAL for the past five calendar years (i.e. CY 2019 till CY 2023) and three quarters of CY 2024 and noted that DIAL has achieved Overall Experience and Overall Satisfaction score of 5.00 during the above- mentioned period and has met all the parameters mentioned in the report.

12.2.5 The Authority noted the CY-wise ACI ASQ Overall Experience and Overall Satisfaction Scores from CY 2019 till CY 2023 and three quarters of CY 2024 for IGIA as follows:

Table 316: ACI ASQ Score for IGI Airport Calendar Year Overall Experience Overall Satisfaction CY 2019 5.00 5.00 CY 2020 5.00 5.00 CY 2021 5.00 5.00 CY 2022 5.00 5.00 CY 2023 5.00 5.00 Q1 CY 2024 5.00 5.00 Q2 CY 2024 5.00 5.00 Q3 CY 2024 5.00 5.00

12.2.6 DIAL has achieved ACI ASQ rating of 5.00 since CY 2019 as per Table 316 above.

13. TARGET REVENUE FOR THE FOURTH CONTROL PERIOD

13.1 DIAL’s Submission regarding Target Revenue for the Fourth Control Period

13.1.1 DIAL has submitted Target Revenue for the Fourth Control Period as per the regulatory building blocks discussed in the earlier chapters.

13.1.2 The summary of Target Revenue submitted by DIAL for the Fourth Control Period is as follows:

13.2 Authority’s Examination of Target Revenue for the Fourth Control Period

13.2.1 The Authority based on its examination across the regulatory building blocks and the proposals including true up for the past control periods has recalculated the Target Revenue for the Fourth Control Period.

13.2.2 The Authority noted that DIAL had completed a major expansion project which has enhanced the capacity to 100 MPPA and has also proposed expansion work (Construction of Pier E) which would result in capacity enhancement to reach handling capacity of 110 MPPA during the Fourth Control Period. Considering the quantum of investment made, there has to be commensurate returns for DIAL which would warrant an increase in Aeronautical Tariff as a consequence.

13.2.3 The Authority also noted that DIAL has been levying Base Airport Charges plus 10% during the entirety of the Third Control Period and continues to do so in FY 2025. The reasons for the same as could be inferred from this Consultation Paper is on account of substantial over recovery during the

Consultation Paper No: 07/ 2024-25 Page 286 of 292TARGET REVENUE FOR THE FOURTH CONTROL PERIOD years in the Second Control Period on account of higher-than-expected traffic along with delay in implementation of the Tariff Order for the Second Control Period.

13.2.4 As mentioned in para 1.8.2 to 1.8.5 of this Consultation Paper, with regard to the issues raised by the Authority in the Civil Appeal against the judgements of the Hon’ble TDSAT, the Authority is of the view that presently it needs to continue the tariff determination exercise in line with the decisions taken in the Tariff Order for the Third Control Period as the matter is sub-judice before the Hon’ble Supreme Court.

13.2.5 Further, the Authority proposes to implement the Hon’ble Supreme Court judgment dated 11th July 2022 and recompute the Aeronautical Taxes based on the regulatory accounts by not treating the Annual Fee pertaining to Aeronautical Revenues as an expense while computing the Aeronautical Taxes as per the directions contained in the said judgement of the Hon’ble Supreme Court.

13.2.6 Based on the detailed examination of each building block of the Third Control Period, there is an over recovery of Rs. 852.04 Cr (refer Table 177), which is being adjusted in the Fourth Control Period.

13.2.7 As a result, inspite of the considerable investment in aeronautical assets and the associated expansion in capacity, the expected increase in Target Revenue has been offset to an extent by this over recovery carried forward from the Third Control Period. Consequently, while DIAL has projected a considerable increase in tariff based on the Hon’ble TDSAT order and the Hon’ble Supreme Court order, the Authority after its thorough examination has proposed a measured and balanced increase taking into consideration the over recovery already earned by DIAL and the efficient cost that could be considered for the tariff determination exercise.

13.2.8 After considering the above, the Authority at the Consultation Stage proposes the following Target

Revenue and Yield Per Pax for the Fourth Control Period:
