Hedging activities and derivatives

Derivatives designated as hedging instruments

The Group uses certain types of derivative financial instruments (viz. forwards contracts, swaps, call options and call spreads) to manage / mitigate its exposure to foreign exchange and interest risk. Further, the Group designates such derivative financial instruments (or its components) as hedging instruments for hedging the exchange rate fluctuation and interest risk attributable to either a recognised item or a highly probable forecast transaction (‘Cash flow hedge’).

The effective portion of changes in the fair value of derivative financial instruments (or its components) that are designated and qualify as cash flow hedges, are recognised in the other comprehensive income and held in hedge reserve - a component of equity. Any gains / (losses) relating to the ineffective portion, are recognised immediately in the statement of profit or loss within finance income / finance costs. The amounts accumulated in equity for highly probable forecast transaction are added to carrying value of non financial asset or non financial liability as basis adjustment, other amounts accumulated in equity are re-classified to the statement of profit or loss in the years when the hedged item affects profit or loss.

At any point of time, when a forecast transaction is no longer expected to occur, the cumulative gains / (losses) that were reported in equity is immediately transferred to the statement of profit or loss.

Cash flow hedges

Hedge has been taken against exposure to foreign currency risk and variable interest outflow on External commercial borrowings, Foreign Letter of Credits and highly probable forecast transactions. Terms of the derivative contracts and their respective impact on OCI and statement of profit or loss is as below:-

Loan

Pay fixed INR and receive USD and pay fixed interest at 4.07% to 9.79% p.a. and receive a variable interest at 3 months SOFR plus 2% - 2.61% p.a, 3 months 3M EURIBOR + 2.50% p.a. and fixed interest at 2.88% to 7.10% p.a. on the notional amount.

Senior secured notes (included in long term interest-bearing loans and borrowings)

Pay fixed INR and receive USD and pay fixed interest in INR at 0.91% to 8.36% p.a. and receive a fixed interest in USD at 0.85% to 7.95% on the notional amount.

The cash flow hedges through Cross Currency Swap (CCS) of USD 1580 (March 31, 2023: USD 685), CCS of EURO 38 (March 31, 2023: 39), Coupon Only Swap (COS) of USD 820 (March 31, 2023: USD 1,255), Principal Only Swap (POS) of USD 355 (March 31, 2023: USD 102) and Call Spread of USD 450 (March 31, 2023: USD 400), foreign currency call options of USD 658 (March 31, 2023: USD 855) and foreign currency forwards of USD 181 (March 31,2023: INR 57), EUR 15 (March 31, 2023: 18) and CNH 3,135 (March 31,2023: 4,674) outstanding at the year ended March 31, 2024 were assessed to be highly effective and a mark to market (loss)/gain of INR (378) (March 31, 2023: INR 2,249, March 31, 2022: INR 763) with a deferred tax liability/(Asset) of INR (82) (March 31, 2023: INR 564, March 31, 2022: INR 228) is included in OCI.

- All of the cash flow hedges were fully effective during the years ended March 31, 2024, 2023 and 2022.

- All of the underlying foreign currency and floating interest rate exposure is fully hedged with cash flow hedges as at March 31, 2024 and 2023.

The expiry dates of cash flow hedge deals range between April 15, 2024 to March 31, 2027.

(2) The amount is netted off by INR 1,064 (March 31, 2023: INR 1,446, March 31, 2022: INR Nil) that represents previously unrecognised DTA which was recognised in the current year.

Acquisition of ReGen Powertech Private Limited

52.

Acquisition of ReGen Powertech Private Limited

The Company through its subsidiary, ReNew Power Services Private Limited (ReNew Power Services) made the successful bid to acquire ReGen Powertech Private Limited (ReGen) and was declared the successful resolution applicant as per order of National Company Law Tribunal (NCLT) dated February 1, 2022. According to the approved resolution plan, ReNew Power Services as the successful resolution applicant, was required to transfer the first tranche of purchase consideration within 30 days, upon which the business would have been transferred to ReNew Power Services and the existing share capital of ReGen would have been extinguished with new shares being issued to ReNew Power Services. Accordingly, ReNew Power Services has paid an amount approximating to INR 716 out of the total consideration, that was supposed to be paid to the Committee of Creditors (CoC) and subsequently, a new board was formed with ReNew nominated directors, and the first meeting was convened on the same date for the issuance of new equity shares to ReNew Power Services.

However, few aggrieved parties challenged the NCLT order approving ReNew Power Services' resolution plan in National Company Law Appellate Tribunal (NCLAT), which through its order dated March 9, 2022, the NCLAT directed deferment of the further implementation of the resolution plan through common order dated August 31, 2023, NCLAT set aside the order of NCLT which had approved the Resolution Plan of Renew Power Services Limited. Appeal against the said order is pending before the Supreme Court of India, in which notice has been issued and the next date of hearing is awaited. Renew Power Services has filed an application before NCLT seeking refund of the payment made by it in compliance and execution of the Resolution Plan which had been approved by NCLT and subsequently set aside by NCLAT. The matter before NCLT for refund of payment is currently pending.

The business activities of ReGen are being currently handled by resolution professional appointed by CoC and ReNew Power Services neither have any control nor significant influence over the relevant activities of ReGen.

On the basis of above facts and considering that the Group does not have control over ReGen in accordance with the definition of control laid out in IFRS 10, the Group has not consolidated ReGen in these consolidated financial statements.

Financial Risk Management Objectives And Policies [Abstract]

Financial risk management objectives and policies

45.

Financial risk management objectives and policies

The financial liabilities comprise loans and borrowings, derivative liabilities, trade payable and other financial liabilities.

The main purpose of these financial liabilities is to finance the Group's operations. The Group's principal financial assets include loans, derivative assets, trade receivables, cash and cash equivalents and other financial assets. The Group is exposed to market risk, credit risk and liquidity risk. The Group's senior management oversees the management of these risks. The Group's senior management is supported by various sub committees that advises on financial risks and the appropriate financial risk governance framework for the Group. These committees provide assurance to the Group's senior management that the Group's financial risk activities are governed by appropriate policies and procedure and that financial risks are identified, measured and managed in accordance with the Group's policies and risk objectives. The Board of Directors reviews and agrees policies for managing each of these risks, which are summarised below:

Market risk

Market risk is the risk that the Group's assets and liabilities will be exposed to due to a change in market prices that determine the valuation of these financial instruments. Market risk comprises three types of risk: interest rate risk, currency risk and other price risk. Financial instruments affected by market risk include loans and borrowings, deposits, investments and derivative financial instruments.

The sensitivity analysis in the following sections relate to the position as at March 31, 2024 and 2023. The sensitivity analyses have been prepared on the basis that the amount of net debt, the ratio of fixed to floating interest rates of the debt and derivatives and the proportion of financial instruments in foreign currencies are all constant and on the basis of hedge designations in place as at March 31, 2024 and 2023.

(i)

Interest rate risk

Interest rate risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Group is exposed to interest rate risk primarily from the external borrowings that are used to finance their operations. In case of external commercial borrowings (ECB) and buyers credit the Group believes that the exposure of Group to changes in market interest rates is insignificant as the respective companies manage the risk by hedging the changes in the market interest rates through cross currency interest rate swaps. The Group also monitors the changes in interest rates and actively refinances its debt obligations to achieve an optimal interest rate exposure.

Interest rate sensitivity

'The following table demonstrates the sensitivity to a reasonable possible change in interest rates on financial liabilities, i.e. floating interest rate borrowings in INR and USD. Interest rate sensitivity has been calculated for borrowings with floating rate of interest. For borrowings with fixed rate of interest sensitivity disclosure has not been made. With all other variables held constant, the Group's profit before tax is affected through the impact on financial liabilities, as follows:

         
        For the year ended March 31,

         
        Increase / decrease in basis points

        Effect on profit/ (loss) before tax

        Increase / decrease in basis points

        Effect on profit/ (loss) before tax

        Increase / decrease in basis points

        Effect on profit/ (loss) before tax

        (-) / + 361

        + / (-) 50

        (-) / + 727

        + / (-) 50

        (-) / + 1,402

The assumed movement in basis points for the interest rate sensitivity analysis is based on the currently observable market environment. Though there is exposure on account of Interest rate movement as shown above but the Group minimises the foreign currency (US dollar) interest rate exposure through derivatives and INR interest rate exposure through re-financing.

(ii)

Foreign currency risk

Foreign currency risk is the risk that the fair value or future cash flows of an exposure will fluctuate because of changes in foreign exchange rates. The Group is exposed to foreign currency risk arising from imports of goods in US dollars. The Group hedges its exposure to fluctuations on the translation into INR of its buyer's / supplier's credit by using foreign currency swaps and forward contracts. The Group has followed a conservative approach for hedging the foreign currency risk so as to not use complex forex derivatives and foreign currency loan. The Group also monitors that the hedges do not exceed the underlying foreign currency exposure. The Group does not undertake any speculative transaction.

Credit risk

Credit risk is the risk that the power procurer will not meet their obligations under a financial instrument or customer contract, leading to a financial loss. The Group is exposed to credit risk from their operating activities (primarily trade receivables) and from its financing activities, including deposits with banks and financial institutions and other financial instruments. The credit risk exposure is insignificant given the fact that substantially whole of the revenues are from state utilities / government entities. The Group only deals with parties which has good credit rating / worthiness given by external rating agencies or based on the Group's internal assessment.

Further the group sought to reduce counterparty credit risk under long-term contracts in part by entering into power sales contracts with utilities or other customers of strong credit quality and we monitor their credit quality on an ongoing basis.

The maximum credit exposure to credit risk for the components of the statement of financial position at March 31, 2024 and 2023 is the carrying amount of all the financial assets except for financial guarantees. The Group’s maximum exposure relating to financial guarantees is disclosed in Note 47(ii) and the liquidity table below.

(i)

Trade receivables

Customer credit risk is managed basis established policies of Group, procedures and controls relating to customer credit risk management. Outstanding customer receivables are regularly monitored. The Group does not hold collateral as security. The group has majorly state utilities / government entities as its customers with high credit worthiness and therefore the group does not see any significant risk related to credit.

The credit quality of the customers is evaluated based on their credit ratings and other publicly available data.

The Group has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment and impairment analysis is performed at each reporting date to measure expected credit losses. The calculation reflects the probability-weighted outcome, the time value of money and reasonable and supportable information that is available at the reporting date about past events, current conditions and forecasts of future economic conditions.

Set out below is the information about the credit risk exposure on the Group’s trade receivables using a provision matrix:


As at March 31, 2024	Trade receivables (days past due)
	0 - 6 months*		6 -12 months		12 -18 months		> 18 months		Total
Gross carrying amount		12,730		970		546		9,967		24,212
Expected credit loss		529		451		149		1,226		2,356


As at March 31, 2023	Trade receivables (days past due)
	0 - 6 months*		6 -12 months		12 -18 months		> 18 months		Total
Gross carrying amount		11,912		6,740		7,189		6,201		32,042
Expected credit loss		233		-		574		548		1,355

* included trade receivables which are not yet due.

(ii)

Financial instruments and credit risk

Credit risk from balances with banks is managed by Group's treasury department. Investments, in the form of fixed deposits, loans and other investments, of surplus funds are made only with banks and financial institutions within credit limits assigned to each counterparty. Counterparty credit limits are reviewed by the Group's treasury department in line with the approved investment policy. The limits are set to minimise the concentration of risks and therefore mitigate financial loss through counterparty's potential failure to make payments.

(iii)

Other financial assets

Credit risk from other financial assets including loans is managed basis established policies of Group, procedures and controls relating to customer credit risk management. Outstanding receivables are regularly monitored. The Group does not hold collateral as security.

(iv)

Equity price risk

Share warrants

The Company has issued warrants to these warrants’ holders (refer Note 39), which entitle these warrants holders to purchase Company’s Class A equity shares. These warrants are classified to be derivative instruments and are recorded at fair value through profit or loss account basis market value of warrants. The Group is exposed to price risk considering the liability in the hands of the Company is impacted through the market price of share warrants.

The Group has determined that an increase / (decrease) of 5% in the market value of warrants would have an impact of INR 38 (March 31, 2023: INR 64; March 31, 2022: INR 122) increase / (decrease) on the profit or loss for the year ended March 31, 2024 of the Group .

Put options

Non-controlling shareholders of RPL have an option to offload their shareholding to the Company in accordance with the terms mentioned in the BCA at fair value of shares on the date of Put for cash. Put option liability with non-controlling interest accounted for at fair value basis volume weight average price of the Company shares over 30 trading days. The changes to the put option liability are accounted for in equity. The Group is exposed to price risk considering the liability in the hands of the Company is impacted through the market price of shares of the Company.

The Group has determined that an increase / (decrease) of 5% in the volume weight average price of the Company shares would have an impact of INR 296 increase / (decrease) on the total equity of the Group for the year ended March 31, 2024 (March 31, 2023: INR 270; March 31, 2022: INR 477).

Liquidity risk

Liquidity risk is the risk that the Group will encounter in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The approach of the Group to manage liquidity is to ensure, as far as possible, that these will have sufficient liquidity to meet their respective liabilities when they are due, under both normal and stressed conditions, without incurring unacceptable losses or risk damage to their reputation. The Group assessed the concentration of risk with respect to refinancing its debt and concluded it to be low. The Group has access to a sufficient variety of sources of funding and debt maturing within 12 months can be rolled over with existing lenders.

The Group relies mainly on long-term debt obligations to fund their construction activities. To the extent available at acceptable terms, the Group utilised non-recourse debt to fund a significant portion of the capital expenditures and investments required to construct and acquire our wind and solar power plants and related assets. The Group's non-recourse financing is designed to limit default risk and is a combination of fixed and variable interest rate instruments. In addition, the debt is typically denominated in the currency that matches the currency of the revenue expected to be generated from the benefiting project, thereby reducing currency risk. The majority of non-recourse debt is funded by banks and financial institutions, with debt capacity supplemented by unsecured loan from related party.

The table below summarises the maturity profile of financial liabilities of the Group based on contractual undiscounted payments:

Basis Of Consolidation [Abstract]

Basis of consolidation

The consolidated financial statements comprise the financial statements of the Company and its subsidiaries as at March 31, 2024. The Group controls an investee if and only if the Group has:

- Power over the investee (i.e., existing rights that give it the current ability to direct the relevant activities of the investee)

- Exposure, or rights, to variable returns from its involvement with the investee; and

- The ability to use its power over the investee to affect its returns

Generally, there is a presumption that a majority of voting rights result in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

- The contractual arrangement(s) with the other vote holders of the investee

- Rights arising from other contractual arrangements

- The Group's voting rights and potential voting rights

The Group re-assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control of the subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the Consolidated Financial Statements from the date the Group gains control until the date the Group ceases to control the subsidiary. All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation.

Profit or loss and each component of other comprehensive income ('OCI') are attributed to the equity holders of the parent of the Group and to the non-controlling interests ('NCI'), even if this results in the non-controlling interests having a deficit balance.

When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies in line with the Group’s accounting policies. The financial statements of all subsidiaries are prepared for the same reporting period as that of the Company for consolidation purposes.

Accounting for transmission line projects entered into by the Group

53.

Accounting for transmission line projects entered into by the Group

During the year ended March 31, 2023, the Group through its subsidiaries engaged in transmission business wherein the subsidiaries had entered into Transmission Services Agreements (TSA) with the Government (Grantor) on BOOM and/or Build, Own, Operate and Transfer (BOOT) basis. The Group through its subsidiaries acts as a transmission licensee.

a) Accounting for transmission line BOOM projects

The TSAs have been entered for term of 35 years, as against the asset’s useful life of 50 years, and as per the terms of the TSA the Group is responsible for constructing the Transmission project, then operating and maintaining these Transmission projects and make them available for use by the Grantor for the entire TSA period. TSAs have a fixed annual levelized tariff for 35 years’ period, subject only to the Group ensuring minimum specified availability of the asset and any reduction in availability will lead to a downward revision in tariff for the relevant period.

Further, as per the electricity regulations applicable at the time of entering TSA, it was mandatory for the Group to hold transmission license in order to transmit electricity through its transmission line. In addition, even after the end of 35 years period; the Government had the ability and right to (i) decide on the extension of the TSA period, including the tariff to be charged or (ii) appoint another operator to operate the infrastructure.

Accordingly, the aforesaid TSA(s), read together with the prevailing regulations, were assessed to be Service Concession Agreements covered under IFRIC 12 and were accounted for using the financial asset model under IFRIC 12.

Subsequently, in January 2024, there are changes in the applicable regulations allowing companies which have entered into TSA under the BOOM model to independently operate the infrastructure without any grantor involvement, including determine tariff for its usage after the TSA term of 35 years. As a result of the changes in the regulations, after the TSA period, the Government no longer has the ability and right to (i) decide on the extension of the TSA period, including the tariff to be charged or (ii) appoint another operator to operate the infrastructure. Based on the Group’s analysis of changes in the regulation duly supported by an external legal advice, these changes in the regulation also apply to all pre-existing TSAs and thus the Group now will have exclusive control over the residual interest, which it has assessed to be significant. Consequentially, the TSA no longer qualifies to be a Service Concession Agreement under IFRIC 12. In the absence of any clear guidance under IFRIC 12, the management has referred guidance under other IFRS dealing with similar and related issues as well as most recent pronouncements of the other standard setting bodies particularly lease modification accounting in IFRS 16 as applicable to the lessor to deal with impact of change in the regulation. Accordingly, the management has applied below accounting in this scenario:

(i) On the date of change in the regulations, the Group has derecognised the contract asset of INR 10,583 recognised toward services rendered till date and recognised PPE at its fair value. The difference between the fair value of the PPE so recognised and the derecognised contract asset, which is a non-monetary government grant, is not material. Subsequent construction cost, for the uncompleted projects, is being added to the PPE. The PPE, once ready to use, is depreciated over its useful life as per IAS 16.

(ii) The Group has also assessed that post change in regulation, the TSA would contain a lease element and a service element which would be separated and accounted for in accordance with IFRS 16 and IFRS 15 respectively. The said lease will be in the nature of an operating lease (refer Note 37).

The Group has two projects under the BOOM model of which construction of one was completed prior to the change in regulations and the other was under construction. Upto the date of change in regulations, the Group had recognised construction revenues of INR 9,987 (including INR 7,478 upto March 31, 2023) and operating and maintenance revenues of INR 0 (upto March 31, 2023: Nil) and consequential contract assets of INR 10,583 and trade receivables of INR 95 were existing on that date. The construction profit of INR 386 million (including INR 289 upto March 31, 2023) for these contracts was included in construction revenue recognised upto the date of change in the regulations. The Group had also recognised finance income on contract assets of INR 691 (upto March 31, 2023: INR 152).

b) Accounting for transmission line BOOT projects under IFRIC 12, 'Service Concession Arrangements'

The TSAs have been entered for term of 35 years and as per the terms of the TSA, the Group is responsible for constructing the Transmission project, then operating and owning these Transmission projects for the entire concession period and thereafter transferring these projects to the grantor.

Such Transmission project have fixed annual levelised tariff as per terms of TSA and such arrangements fall under the purview IFRIC 12, 'Service Concession Arrangements' and have been accounted as per financial asset model.

The change in regulation mentioned under (a) above does not impact TSAs covered under the BOOT model and accounting thereof as in these cases the Company is obligated to transfer the assets to the grantor at the end of the TSA period.

c) The movement of contract assets during the year ended March 31, 2024 and 2023 are summarised below:


	As at March 31,
	2023		2024			2024

Current		572		216			3

* includes profit of INR 161 (March 31, 2023: INR 292).

** includes INR 95 which was transferred to trade receivable

d) The transaction price allocated to the remaining construction activities and operation and maintenance services is approximately INR 661 and INR 632, respectively (March 31, 2023 INR 4,315 and INR 2,761 respectively). As the construction activities progress, the performance obligations will continue to be fulfilled and the remaining revenue would be recognised for projects covered under IFRIC 12. The Group expects to complete the construction activities within next year. Further, operating and maintenance services shall be completed over the tenure of TSAs.

Group as a lessor

As described in Note 53(a), the Group has entered into Transmission Services Agreements (TSAs) to set-up two transmission projects on Build, Own, Operate and Maintain (BOOM) basis for a 35-year period as against the economic useful life of 50 years. Out of two projects, construction on one project is completed and other one is still under construction. As more fully explained in note 53(a), pursuant to change in the regulations, the Group has assessed and concluded that IFRIC 12 accounting is no longer applicable to these TSAs; rather, these TSAs would contain a lease of Transmission Line under IFRS 16, in addition to service element under IFRS 15. The said lease is assessed to be in the nature of the operating lease. The lease of one project, for which construction was completed, has commenced during the year. The lease of under construction project is expected commence in the coming financial year once construction is completed.

Both the agreements provide for fixed lease rentals that progressively reduce for the first 8 years and then remain constant for remainder of the TSA tenure, subject only to the Group ensuring minimum specified availability of the asset.

The rental income recognised by the Group on straight-line basis during the year is INR 222 (years ended March 31, 2023 and 31 March 2022: INR Nil). Future minimum rentals receivable under non-cancellable operating leases as at March 31, 2024 are: (i) Within one year- INR 728 and INR 347, (ii) between 1 - 2 years - INR 726 and INR 347, (iii) between 2 - 3 years - INR 725 and INR 346, (iv) between 3 - 4 years - INR 725 and INR 346, (v) between 4 - 5 years - INR 686 and INR 328, and (vi) More than 5 years - INR 15,286 and INR 7,719; respectively for leases which have commenced operations and which are expected to commence operation in future.

The management of the Group assessed that cash and cash equivalents, trade receivables (current), bank balances other than cash and cash equivalents, short term loans, trade payables, short term interest-bearing loans and borrowings, other current financial liabilities and other current financial assets approximate their carrying amounts largely due to the short-term maturities of these instruments.

For all other instruments, following methods and assumptions were used to estimate the fair values:

Fair values of the Group’s interest bearing loans and borrowings including current maturities are determined by using Discounted Cash Flow (DCF) method using discount rate that reflects the issuer’s borrowing rate (prevailing interest rate in the market) as at the end of the reporting period. They are classified as level 3 fair values in the fair value hierarchy due to the inclusion of unobservable inputs including credit risk. The non-performance risk as at March 31, 2024 and 2023 was assessed to be insignificant.

ii)

Fair values of the liability component of compulsory convertible debentures and optionally convertible debentures are determined by using DCF method using discount rate that reflects the borrowing rate (prevailing interest rate in the market) as at the end of the reporting period. They are classified as level 3 fair values in the fair value hierarchy due to the inclusion of unobservable inputs including own credit risk. The own non-performance risk as at March 31, 2024 and 2023 was assessed to be insignificant.

iii)

Fair values of the non-current trade receivables, bank deposits and security deposits given are determined by using DCF method using discount rate that reflects the lending rate (prevailing interest rate in the market) as at the end of the reporting period. They are classified as level 3 fair values in fair value hierarchy due to inclusion of unobservable inputs including counterparty credit risk.

iv)

The Group enter into derivative financial instruments with various counterparties, principally financial institutions with investment grade credit ratings. Cross currency interest rate swaps are valued using valuation techniques, which employs the use of market observable inputs. The models incorporate various fair value level 2 inputs including the credit quality of counterparties, foreign exchange spot and forward rates, yield curves of the currency, interest rate curves and forward rate curves of the underlying instrument. The changes in counterparty credit risk had no material effect on the hedge effectiveness assessment for derivatives designated in hedge relationships.

(a) the number of ordinary shares outstanding from April 1, 2021 to August 23, 2021 is computed on the basis of the weighted average number of ordinary shares of RPL outstanding during the period multiplied by the exchange ratio established in the Transaction (i.e., 1 RPL share to 0.8289 Company Share); and

(b) the number of ordinary shares outstanding from August 24, 2021 to March 31, 2022, April 1, 2022 to March 31, 2023 and April 1, 2023 to March 31, 2024 is the actual number of ordinary shares of the Company outstanding during that period.

@ Class B share is not the most subordinate to other classes of equity instruments as per IAS 33. Refer Note 16 for terms of Class B share.

^ Class D share is a redeemable share and therefore, is not considered as ordinary shares as per IAS 33. Refer Note 16 for terms of Class D share.

# Since the effect of all potential equity shares other than mentioned above were anti-dilutive in year ended March 2024, 2023 and 2022, it has not been considered for the purpose of computing diluted earnings per share.

Capital Management [Abstract]

Capital management

For the purpose of the capital management, capital includes issued equity capital, compulsorily convertible debentures, compulsorily convertible preference shares, optionally convertible debentures, share premium and all other equity reserves attributable to the equity holders of the parent. The primary objective of the Group's management is to maximise the shareholder value.

The Group manages its capital structure and makes adjustments in light of changes in economic conditions and the requirements of the financial covenants.

To maintain or adjust the capital structure, the Group may adjust the dividend payment to shareholders, return capital to shareholders or issue new shares. The Group monitor capital using a gearing ratio, which is net debt divided by total capital plus net debt. The Group includes within net debt, interest bearing loans and borrowings and other payables, less cash and short-term deposits. The Group systematically evaluates opportunities for managing its assets including that of buying new assets, partially or entirely sell existing assets and potential new joint ventures. Crystallisation of any such opportunity shall help the Group in improving the overall portfolio of assets, cash flow management and shareholder returns.

The policy of the Group is to keep the gearing ratio of the power project to 3:1 during the construction phase and aim to enhance it to 4:1 post the construction phase. This is in line with the industry standard ratio. The current gearing ratios of the various projects in the Group is between 3:1 to 4:1. In order to achieve this overall objective, the capital management of the Group, amongst other things, aims to ensure that they meet financial covenants attached to the interest-bearing loans and borrowings that define capital structure requirements.

There are no unremediated breaches of the covenants on any interest bearing loans and borrowings as at March 31, 2024 and 2023.

No changes were made in the objectives, policies or processes for managing capital during the years ended March 31, 2024, 2023 and 2022.

ReNew Solar Energy Private Limited and its subsidiaries and two solar rooftop projects

On October 4, 2021, the Board of the Company passed a resolution to sell its two solar roof top projects housed in RPL and ReNew Solar Power Private Limited as well as 100% stake in ReNew Solar Energy Private Limited (ReNew Solar) along with all wholly owned subsidiaries under ReNew Solar as listed below (hereinafter referred to as "Solar Energy and its subsidiaries"), which are carrying out business of operating solar roof top projects in India with commissioned capacity of 117 MW solar rooftop project. ReNew Solar along with its subsidiaries falls under solar power reportable segment. Following wholly owned subsidiaries under ReNew Solar were proposed to be sold:


(i) Renew Distributed Solar Services Private Limited	(xi) Renew Sun Ability Private Limited

(iii) Renew Distributed Solar Power Private Limited	(xiii) Renew Sun Flash Private Limited

(viii) Renew Solar Daylight Energy Private Limited	(xviii) Renew Green Solutions Private Limited
(ix) Zorya Distributed Power Services Private Limited	(xix) Renew Mega Green Private Limited
(x) Renew Clean Tech Private Limited	(xx) Renew Surya Mitra Private Limited

On October 4, 2021, the loss of control over two solar rooftop projects and Solar Energy and its subsidiaries within the next twelve months became highly probable and met the criteria to be classified as a disposal group held for sale and accordingly, assets and liabilities related to the ReNew Solar along with its subsidiaries were classified as held for sale. The Company had entered into a share purchase agreement with Fourth Partner Energy for sale of Solar Energy and its subsidiaries and two rooftop projects. As part of the share purchase agreement, the Company has also executed deed of assignment for two solar rooftop projects housed in RPL and ReNew Solar Power Private Limited wherein the Company has irrevocably conveyed all the rights, title and interest in the amounts due to Fourth Partner Energy till the time it executes a separate novation agreement.

The total sale consideration on account of above transactions was INR 6,047 against net assets of INR 5,820 which resulted in a gain of INR 227. The transaction for sale of Solar Energy and its subsidiaries was completed on January 18, 2022. As at March 31, 2023, the transaction for sale of two solar rooftop projects is not completed which have assets of INR 64 (March 31, 2022: INR 93).

During the year ended March 31, 2024, the aformentioned novation agreement in relation to both the roof top projects could not get executed and the Group decided against its plan to sell both rooftop projects to Fourth Partner. Accordingly, the Group ceased to classify both of these projects as held for sale. The depreciation charged on these two projects for the year ended March 31, 2024 amounted to INR 18.

Refer Note (c) below for assets held for sale and the details of assets and liabilities derecognised on account of the aforementioned sale of subsidiaries.

Disclosure of Summary of Material Accounting Policies [Abstract]

Summary of material accounting policies

4.1.

Summary of material accounting policies

The following are the material accounting policies applied by the Group in preparing its consolidated financial statements:

Business combinations and goodwill

Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred measured at acquisition date fair value and the amount of any non-controlling interests in the acquiree. For each business combination, the Group elects whether to measure the non-controlling interests in the acquiree at fair value or at the proportionate share of the acquiree’s identifiable net assets. Acquisition-related costs are expensed as incurred and included in other expenses.

The Group determines that it has acquired a business when the acquired set of activities and assets include an input and a substantive process that together significantly contribute to the ability to create outputs. The acquired process is considered substantive if it is critical to the ability to continue producing outputs, and the inputs acquired include an organised workforce with the necessary skills, knowledge, or experience to perform that process or it significantly contributes to the ability to continue producing outputs and is considered unique or scarce or cannot be replaced without significant cost, effort, or delay in the ability to continue producing outputs.

The Group has an option to apply a ‘concentration test’ that permits a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the optional concentration test is not met, or the Group elects not to apply the test, the Group performs detailed assessment to determine whether an acquired set of activities and assets is a business.

At the acquisition date, the identifiable assets acquired and the liabilities assumed are recognised at their acquisition date fair values. For this purpose, the liabilities assumed include contingent liabilities representing present obligation and they are measured at their acquisition fair values irrespective of the fact that outflow of resources embodying economic benefits is not probable. However, the following assets and liabilities acquired in a business combination are measured at the basis indicated below:

- Deferred tax assets or liabilities and the assets or liabilities related to employee benefit arrangements are recognised and measured in accordance with IAS 12 - Income Taxes and IAS 19 - Employee Benefits respectively.

- Liabilities or equity instruments related to share based payment arrangements of the acquiree or share – based payments arrangements of the Group entered into to replace share-based payment arrangements of the acquiree are measured in accordance with IFRS 2 Share-based Payment at the acquisition date.

- Assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5 - Non-current Assets Held for Sale and Discontinued Operations are measured in accordance with that standard.

- Reacquired rights are measured at a value determined on the basis of the remaining contractual term of the related contract. Such valuation does not consider potential renewal of the reacquired right.

- Potential tax effects of temporary differences and carry forwards of an acquiree that exist at the acquisition date or arise as a result of the acquisition are accounted in accordance with IAS 12.

When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree.

If the business combination is achieved in stages, any previously held equity interest is re-measured at its acquisition date fair value and any resulting gain or loss is recognised in the statement of profit or loss or OCI, as appropriate.

Any contingent consideration to be transferred by the acquirer is recognised at fair value at the acquisition date. Contingent consideration classified as an asset or liability that is a financial instrument and within the scope of IFRS 9 Financial Instruments, is measured at fair value with changes in fair value recognised in the statement of profit or loss in accordance with IFRS 9. Other contingent consideration that is not within the scope of IFRS 9 is measured at fair value at each reporting date with changes in fair value recognised in statement of profit or loss. Contingent consideration classified as equity is not remeasured and its subsequent settlement is accounted for within equity.

Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred and the amount recognised for non-controlling interests, and any previous interest held, over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is in excess of the aggregate consideration transferred, the Group re-assesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed and reviews the procedures used to measure the amounts to be recognised at the acquisition date. If the reassessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the gain is recognised in statement of profit or loss.

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group’s cash-generating units or group of CGUs that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units.

A cash generating unit (CGU) or group of CGUs to which goodwill has been allocated is tested for impairment annually on March 31, or more frequently when there is an indication that the unit may be impaired. If the recoverable amount of the cash generating unit is less than its carrying amount, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro rata based on the carrying amount of each asset in the unit. Any impairment loss for goodwill is recognised in the statement of profit or loss. An impairment loss recognised for goodwill is not reversed in subsequent periods.

Where goodwill has been allocated to a cash-generating unit and part of the operation within that unit is disposed of, the goodwill associated with the disposed operation is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed in these circumstances is measured based on the relative values of the disposed operation and the portion of the cash-generating unit retained.

When the Group acquires controlling interest in an entity or a group of assets or net assets that is not a business, the Group allocates the cost of the group between the individual identifiable assets acquired (including intangible assets) and liabilities assumed based on their relative fair values at the date of purchase and these acquisitions do not give rise to the goodwill. The cost of the group of assets is the sum of all consideration given, any NCI recognised, and transaction costs incurred if any.

Investment in jointly controlled entities (joint ventures)

A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control.

The considerations made in determining joint control are similar to those necessary to determine control over subsidiaries. The Group’s investment in its joint venture are accounted for using the equity method.

Under the equity method, the investment in a joint venture is initially recognised at cost. The carrying amount of the investment is adjusted to recognise changes in the Group’s share of net assets of the joint venture since the acquisition date. Goodwill relating to the joint venture is included in the carrying amount of the investment and is not tested for impairment separately.

The statement of profit or loss reflects the Group’s share of the results of operations of the joint venture. Any change in OCI of those investees is presented as part of the Group’s OCI. In addition, when there has been a change recognised directly in the equity of the joint venture, the Group recognises its share of any changes, when applicable, in the statement of changes in equity. Unrealised gains and losses resulting from transactions between the Group and the joint venture are eliminated to the extent of the interest in the joint venture.

The aggregate of the Group’s share of profit or loss of a joint venture is shown on the face of the statement of profit or loss and represents profit or loss after tax and non-controlling interests in the subsidiaries of the joint venture.

The financial statements of the joint venture are prepared for the same reporting period as the Group. When necessary, adjustments are made to bring the accounting policies in line with those of the Group.

After application of the equity method, the Group determines whether it is necessary to recognise an impairment loss on its investment in its associate or joint venture. At each reporting date, the Group determines whether there is objective evidence that the investment in the joint venture is impaired. If there is such evidence, the Group calculates the amount of impairment as the difference between the recoverable amount of the joint venture and its carrying value, and then recognises the loss within ‘Share of (loss) / profit of jointly controlled entities’ in statement of profit or loss.

Upon loss of joint control over the joint venture, the Group measures and recognises any retained investment at its fair value. Any difference between the carrying amount of the joint venture upon loss of joint control and the fair value of the retained investment and proceeds from disposal is recognised in statement of profit or loss.

Interests in joint operations

Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets, and obligations for the liabilities, relating to the arrangement.

When a Group entity undertakes its activities under joint operations, the Group as a joint operator recognises in relation to its interest in a joint operation:

•

its assets, including its share of any assets held jointly;

•

its liabilities, including its share of any liabilities incurred jointly;

•

its revenue from the sale of its share of the output arising from the joint operation;

•

its share of the revenue from the sale of the output by the joint operation; and

•

its expenses, including its share of any expenses incurred jointly.

The Group accounts for the assets, liabilities, revenue and expenses relating to its interest in a joint operation in accordance with the IFRS Standards applicable to the particular assets, liabilities, revenue and expenses.

Current versus non-current classification

The Group segregates assets and liabilities into current and non-current categories for presentation in the statement of financial position after considering its normal operating cycle and other criteria set out in IAS 1, “Presentation of financial statements”. For this purpose, current assets and liabilities include current portion of non-current assets and liabilities respectively. Deferred tax assets and liabilities are always classified as non-current.

The operating cycle is the time between the acquisition of assets for processing and their realisation / settlement in cash and cash equivalents. The Group has identified period upto twelve months as their operating cycle for classification of their current assets and liabilities.

Fair value measurement

The Group measures financial instruments, such as, derivatives at fair value at each reporting date.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

•

In the principal market for the asset or liability, or

•

In the absence of a principal market, in the most advantageous market for the asset or liability

The principal or the most advantageous market must be accessible by the Group.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest. The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximising the use of relevant observable inputs and minimising the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the consolidated financial statements are categorised within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

•

Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities

•

Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable

•

Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable

For assets and liabilities that are recognised in the financial statements at fair value on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by re-assessing categorisation (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

The management of the Group determines the policies and procedures for both recurring fair value measurement, such as unquoted financial assets, and for non-recurring measurement, such as assets held for sale.

At each reporting date, the management of the Group analyses the movements in the values of assets and liabilities which are required to be remeasured or re-assessed as per the accounting policies of the Group. The management also compares the change in the fair value of each asset and liability with relevant external sources to determine whether the change is reasonable.

This note summarises the accounting policy for determination of fair value. Other fair value related disclosures are given in the relevant notes as following:

Revenue recognition

(i)

Revenue

Revenue is recognised when control of the goods or services are transferred to the customer at an amount that reflects the consideration to which the Group expects to be entitled in exchange for those goods or services. The Group has generally concluded that it is the principal in its revenue arrangements, because it typically controls the goods or services before transferring them to the customer.

Sale of power

Revenue from supply of power is recognised over time because the customer simultaneously receives and consumes benefits on the supply of units generated from plant to the grid as per the terms of the Power Purchase Agreement (PPA) entered into with the customers.

The Group considers whether there are other promises in the contract that are separate performance obligations to which a portion of the transaction price needs to be allocated. In determining the transaction price for the sale of power, the Group considers the effects of variable consideration. There is only one performance obligation in the arrangement and therefore, allocation of transaction price is not required.

Revenue from Engineering, Procurement and Construction (EPC) Contracts

Revenue from provision of service is recognised over a period of time on the percentage of completion method. Percentage of completion is determined as a proportion of cost incurred to date to the total estimated contract cost. Profit on contracts is recognised on percentage of completion method and losses are accounted as soon as these are anticipated. In case the total cost of a contract based on technical and other estimates is expected to exceed the corresponding contract value such expected loss is provided for. The revenue on account of extra claims on construction contracts are accounted for at the time of acceptance in principle by the customers due to uncertainties attached.

Contract revenue earned in excess of billing has been reflected under other current assets and billing in excess of contract revenue has been reflected under current liabilities in the statement of financial position.

Variable consideration

If the consideration in a contract includes a variable amount, the Group estimates the amount of consideration to which it will be entitled in exchange for transferring the goods or service to the customer. The variable consideration is estimated at contract inception and constrained until it is highly probable that a significant revenue reversal in the amount of cumulative revenue recognised will not occur when the associated uncertainty with the variable consideration is subsequently resolved. To estimate the variable consideration, the Group applies the method that it expects best predicts the amount of consideration to which the entity will be entitled based on the terms of the contract.

- Rebates

In some PPAs, the Group provide rebates in invoice if payment is made before the due date. These are adjusted against revenue and are offset against amounts payable by the customers.

Revenue on account of service concession arrangements

IFRIC 12, 'Service Concession Arrangements' deals with the treatment to be applied by the operator for public-to-private service concession arrangements. Service concession arrangement fall within the scope of IFRIC 12 when the following two conditions are met:

i) the grantor controls or regulates what services the operator must provide with the infrastructure, to whom it must provide them, and at what price; and

ii) the grantor controls - through ownership, beneficial entitlement or otherwise - any significant residual interest in the infrastructure at the end of the term of the arrangement.

The financial asset model according to paragraph 16 of IFRIC 12 applies if the operator has an unconditional contractual right to receive cash or another financial asset from or at the direction of the grantor for the construction services; the grantor has little, if any, discretion to avoid payment, usually because the agreement is enforceable by law. The operator has an unconditional right to receive cash if the grantor contractually guarantees to pay the operator (a) specified or determinable amounts or (b) the shortfall, if any, between amounts received from users of the public service and specified or determinable amounts, even if payment is contingent on the operator ensuring that the infrastructure meets specified quality or efficiency requirements.

Revenue related to construction services under a service concession arrangement is recognised over time because the grantor controls as the asset as it is constructed by the Group. Operation or service revenue is recognised over time in the period in which the services are provided by the Group because the grantor simultaneously receives and consumes the benefits provided the Group. The total expected consideration is allocated to the performance obligations based on the relative stand-alone selling prices of the construction services and operation services, taking into account the significant financing component.

The Group recognises a contract asset for its right to receive consideration for the construction services and accounts for the significant financing component in the arrangement in accordance IFRS 15. Once it is established that Group has an unconditional right (other than that of the passing of time) to receive consideration for the construction services, the amounts due from the grantor are accounted for in accordance with IFRS 9, 'Financial Instruments' as receivables.

(ii)

Contract balances

Contract assets

A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Group performs by transferring goods or services to a customer when that right is conditioned on something other than the passage of time. Contract assets are subject to impairment assessment.

Contract liabilities

A contract liability is the obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. If a customer pays consideration before the Group transfers goods or services to the customer, a contract liability is recognised when the payment is made or the payment is due (whichever is earlier). Contract liabilities are recognised as revenue when the Group performs under the contract (i.e., transfers control of the related goods or services to the customer).

Trade receivables

A receivable represents the Group’s right to an amount of consideration that is unconditional (i.e., only the passage of time is required before payment of the consideration is due). Refer to accounting policies of financial assets in section (s) Financial instruments – initial recognition and subsequent measurement.

Foreign currencies

The consolidated financial statements have been presented in INR, which is the Group's presentation currency as business activities of the Group are carried through RPL and its subsidiaries, whose functional currency is INR. The functional currency of the Company is USD as business activities of the Company are carried in USD.

The functional currency for each entity in the Group is determined as the currency of the primary economic environment in which it operates and items included in the financial statements of each entity are measured using that functional currency.

Foreign currency transactions

Transactions in foreign currencies are initially recorded by the Group’s entities at their respective functional currency spot rates at the date the transaction first qualifies for recognition. Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency spot rates of exchange at the reporting date. Differences arising on settlement or translation of monetary items are recognised in the consolidated statement of profit or loss.

Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value is determined.

Group companies

On consolidation, the assets and liabilities of foreign operations are translated into INR at the rate of exchange prevailing at the reporting date and their statements of profit or loss are translated at exchange rates prevailing at the dates of the transactions. For practical reasons, the group uses an average rate to translate income and expense items, if the average rate approximates the exchange rates at the dates of the transactions. The exchange differences arising on translation for consolidation are recognised in OCI. On disposal of a foreign operation, the component of OCI relating to that particular foreign operation is recognised in the statement of profit or loss.

Taxes

Current income tax

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date. Current income tax relating to items recognised outside profit or loss is recognised outside the statement of profit or loss (either in OCI or equity). Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and considers whether it is probable that a taxation authority will accept an uncertain tax treatment. The Group reflects the effect of uncertainty for each uncertain tax treatment by using either most likely method or expected value method, depending on which method predicts better resolution of the treatment. Current income tax assets and liabilities are offset if a legally enforceable right exists to set off these and intends either to settle on a net basis, or to realise the asset and settle the liability simultaneously.

Deferred tax

Deferred tax is provided using the asset-liability method on temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred tax liabilities are recognised for all taxable temporary differences, except:

- When the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, (i) affects neither the accounting profit nor taxable profit or loss and (ii) and does not give rise to equal taxable and deductible temporary differences.

- In respect of taxable temporary differences associated with investments in subsidiaries and interests in joint ventures, if the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

Deferred tax assets are recognised for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognised to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilised except:

- When the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, (i) affects neither the accounting profit nor taxable profit or loss and (ii) and does not give rise to equal taxable and deductible temporary differences.

- in respect of deductible temporary differences associated with investments in subsidiaries and interests in joint ventures, deferred tax assets are recognised only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilised.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilised. Unrecognised deferred tax assets are re-assessed at each reporting date and are recognised to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

In situations where Group is entitled to a tax holiday under the Income-tax Act, 1961, enacted in India, no deferred tax (asset or liability) is recognised in respect of temporary differences which reverse during the tax holiday period. Deferred taxes in respect of temporary differences which reverse after the tax holiday period are recognised in the period in which the temporary differences originate. However, the Group restricts the recognition of deferred tax assets to the extent that it has become probable that sufficient future taxable income will be available against which such deferred tax assets can be realised.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the asset is realised or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

Deferred tax relating to items recognised outside profit or loss is recognised outside statement of profit or loss (either in OCI or equity). Deferred tax items are recognised in correlation to the underlying transaction either in OCI or directly in equity.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

Minimum Alternate Tax

Minimum alternate tax (MAT) paid in a year is charged to the statement of profit or loss as current tax for the year. The deferred tax asset is recognised for MAT credit available only to the extent that it is probable that the concerned company will pay normal income tax during the specified period, i.e., the period for which MAT credit is allowed to be carried forward. In the year in which the company recognises MAT credit as an asset, it is created by way of credit to the statement of profit or loss and shown as part of deferred tax asset. The company reviews the “MAT credit entitlement” asset at each reporting date and writes down the asset to the extent that it is no longer probable that it will pay normal tax during the specified period.

Government grants

Government grants is recognised where there is reasonable assurance that the grant will be received and all attached conditions will be compiled with. When the grant related to an expense item, it is recognised as other income on a systematic basis over the periods that related costs, for which it is intended to compensate, are expensed. When grant is related to an asset, it is recognised as income in equal amounts over the expected useful life of related asset.

The Group presents grants related to an expense item as income in the statement of profit or loss. The Group does not receive any material non- monetary asset as government grant.

Property, plant and equipment

Capital work in progress is stated at cost, net of accumulated impairment loss, if any. Property, plant and equipment (PPE) except freehold land is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. Such cost includes the cost of replacing part of the plant and equipment and borrowing costs for long-term construction projects if the recognition criteria are met. When significant parts of plant and equipment are required to be replaced at intervals, the Group depreciates them separately based on their specific useful lives. Likewise, when a major inspection is performed, its cost is recognised in the carrying amount of the plant and equipment as a replacement if the recognition criteria are satisfied. All other repair and maintenance costs are recognised in the statement of profit or loss as incurred. Land is stated at cost net of accumulated impairment losses and is not depreciated.

The present value of the expected cost for the decommissioning of an asset after its use is included in the cost of the respective asset if the recognition criteria for a provision are met.

Subsequent costs

The cost of replacing a part of an item of property, plant and equipment is recognised in the carrying amount of the item of property, plant and equipment, if it is probable that the future economic benefits embodied within the part will flow to the Group and its cost can be measured reliably with the carrying amount of the replaced part getting derecognised. The cost for day-to-day servicing of property, plant and equipment are recognised in statement of profit or loss as and when incurred.

Derecognition

An item of property, plant and equipment and any significant part initially recognised is derecognised upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statement of profit or loss when the asset is derecognised. Gains or losses arising from de-recognition of property, plant and equipment are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognised in the statement of profit or loss when the asset is derecognised.

Intangible assets

Intangible assets acquired separately are measured in initial recognition at cost. The cost of intangible assets and intangible assets under development acquired in a business combination is their fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortisation and accumulated impairment losses and intangible assets under development are carried at cost less any accumulated impairment losses. The useful lives of intangible assets are assessed as either finite or indefinite.

Intangible assets with finite lives are amortised over the useful life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. An intangible asset is derecognised upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising upon derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statement of profit or loss.

Customer related intangibles are capitalised if they meet the definitions of an intangible asset and the recognition criteria are satisfied. Customer-related intangibles acquired as part of a business combination are valued at fair value and those acquired separately are measured at cost. Such intangibles are amortised over the remaining useful life of the customer relationships or the period of the contractual arrangements.

Depreciation / amortisation of property, plant and equipment and intangible assets

Depreciation and amortisation are calculated on a straight-line basis over the estimated useful lives of the assets as follows:


	Category		Life (in years)
	Plant and equipment (solar rooftop projects)*		25 or terms of PPA, whichever is less (15-25)
	Plant and equipment (solar power projects)*		35
	Plant and equipment (wind power projects)*		30
	Plant and equipment (hydro power projects)		25-45
	Plant and equipment (transmission projects)*		50
	Plant and equipment (others)		5-18
	Office equipment		5
	Furniture and fixture		10
	Computers		3
	Computer servers		6
	Computer softwares		3-6
	Other Intangible assets		5
	Customer contracts		25
	Development rights		25
	Leasehold improvements		Useful life or lease term (5), whichever is lower
	Building (Temporary structure)		3
	Building (other than Temporary structure)		30

The residual values, useful lives and methods of depreciation and amortisation of property, plant and equipment and intangible assets are reviewed at each financial period end and adjusted prospectively, if appropriate.

Inventories

Inventories are valued at the lower of cost and net realisable value. Cost includes cost of purchase and other costs incurred in bringing the inventories to their present location and condition. Cost is determined using weighted average method.

Net realisable value is the estimated selling price in the ordinary course of business, less estimated costs necessary to make the sale.

Borrowing costs

Borrowing costs consist of interest, discount on issue, premium payable on redemption and other costs that an entity incurs in connection with the borrowing of funds (this cost also includes exchange differences to the extent regarded as an adjustment to the borrowing costs). The borrowing costs are amortised basis the Effective Interest Rate (EIR) method over the term of the loan.

Borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalised during the period. The amount amortised for the period from disbursement of borrowed funds upto the date of capitalisation of the qualifying asset is added to the cost of qualifying assets. All other borrowing costs are recognised in statement of profit or loss under the head finance cost in the period in which they are incurred

To the extent, group borrows funds for general purpose and uses them for the purpose of obtaining a qualifying asset, the group determines the amount of borrowing costs eligible for capitalisation by applying a capitalisation rate to the expenditures on that asset. The capitalisation rate used is weighted average of the borrowing costs applicable to the borrowings of the group that are outstanding during the period, other than borrowings made specifically for the purpose of obtaining a qualifying asset. In case any specific borrowing remains outstanding after the related asset is ready for its intended use or sale, that borrowing becomes part of the funds that an entity borrows generally when calculating the capitalisation rate on general borrowings.

Leases

The Group assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

As a lessee

The Group applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Group recognises lease liabilities to make lease payments and right-of-use assets representing the right to use the underlying assets.

Right-of-use assets

The Group recognises right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and accumulated impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognised, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Right-of-use assets are depreciated on a straight-line basis over the shorter of the lease term and the estimated useful lives of the assets, as follows:

•

Leasehold land: 13 to 35 years

•

Building: 3 to 5 years

If ownership of the leased asset transfers to the Group at the end of the lease term or the cost reflects the exercise of a purchase option, depreciation is calculated using the estimated useful life of the asset.

The right-of-use assets are also subject to impairment. Refer to the accounting policies in section (o) Impairment of non-financial assets.

ii)

Lease liabilities

At the commencement date of the lease, the Group recognises lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in-substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group and payments of penalties for terminating the lease, if the lease term reflects the Group exercising the option to terminate. Variable lease payments that do not depend on an index or a rate are recognised as expenses (unless they are incurred to produce inventories) in the period in which the event or condition that triggers the payment occurs.

In calculating the present value of lease payments, the Group uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the lease payments (example: changes to future payments resulting from a change in an index or rate used to determine such lease payments) or a change in the assessment of an option to purchase the underlying asset.

iii)

Short-term leases and leases of low-value assets

The Group applies the short-term lease recognition exemption to its short-term leases (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered to be low value. Lease payments on short-term leases and leases of low value assets (lease of assets worth less than INR 0.5) are recognised as expense on a straight-line basis over the lease term.

As a lessor

Leases in which the Group does not transfer substantially all the risks and rewards of ownership of an asset are classified as operating leases. Rental income from operating lease is recognised on a straight-line basis over the term of the relevant lease. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognised over the lease term on the same basis as rental income. Contingent rents are recognised as revenue in the period in which they are earned. When a contract includes both lease and non-lease component, the Group applies IFRS 15 to allocate the consideration under the contract to each component.

Impairment of non-financial assets

The Group assesses, at each reporting date, whether there is an indication that an asset may be impaired. If any indication exists, or when annual impairment testing for a cash-generating unit (CGU) asset is required in case of CGU which includes Goodwill, the Group estimates its recoverable amount. Recoverable amount is the higher of an asset’s or CGU fair value less costs of disposal and its value in use. Recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or group of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.

In assessing value in use, the estimated future cash flows are discounted to their present value using a pre -tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. In determining fair value less costs of disposal, recent market transactions are taken into account. If no such transactions can be identified, an appropriate valuation model is used. The higher of value-in-use or fair value less costs of disposal is regarded as the recoverable amount.

The Group bases its impairment calculation on detailed budgets and forecast calculations, which are prepared separately for each of the Group’s CGUs to which the individual assets are allocated. These budgets and forecast calculations generally cover the remaining life of the project.

Impairment losses of continuing operations, including impairment on inventories, are recognised in the statement of profit or loss.

Share based payments

Company provides additional benefits to certain members of senior management and employees of the Group in the form of share-based payments, whereby employees render services as consideration for equity instruments (equity-settled transactions).

Equity-settled transactions

The cost of equity-settled transactions is determined by the fair value at the date when the grant is made using an appropriate valuation model.

The cost is recognised, together with a corresponding increase in share-based payment reserve in equity, over the period in which the performance and / or service conditions are fulfilled in employee benefit expenses. The cumulative expense recognised for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Group's best estimate of the numbers of equity instruments that will ultimately vest. The statement of profit or loss expense or credit for a period represents the movement in cumulative expense recognised as at the beginning and end of that period and is recognised in employee benefit expense.

Service and non-market performance conditions are not taken into account when determining the grant date fair value of awards, but the likelihood of the conditions being met is assessed as part of the Group's best estimate of the number of equity instruments that will ultimately vest. Market performance conditions are reflected within the grant date fair value. Any other condition attached to an award, but without associated service requirement, are considered to be non-vesting conditions. Non-vesting conditions are reflected in the fair value of an award and lead to an immediate expensing of an award unless there are also service and / or performance conditions.

No expense is recognised for awards that do not ultimately vest because of non-market performance and / or service conditions have not been met. Where awards include a market or non-vesting condition, the transaction are treated as vested irrespective of whether the market or non-vesting condition is satisfied, provided that all other performance and/or service condition are satisfied.

When the terms of an equity-settled award are modified or replaced with new share based payment scheme, the minimum expense recognised is the grant date fair value of the unmodified award, provided the original vesting terms of the award are met. An additional expense, measured as at the date of modification, is recognised for any modification that increases the total fair value of the share-based payment transaction, or is otherwise beneficial to the employee. Where an award is cancelled by the entity or by the counterparty, any remaining element of the fair value of the award is expensed immediately through the statement of profit or loss.

The dilutive effect of outstanding options is reflected as additional share dilution in the computation of diluted earnings per share.

Retirement and other employee benefits

Retirement benefit in the form of provident fund is a defined contribution scheme. The Group has no obligation, other than the contribution payable to the provident fund. The Group recognises contribution payable to provident fund scheme as an expense, when an employee renders the related service.

Remeasurements comprising of actuarial gain and losses, the effect of the asset ceiling, excluding amount recognised in the net interest on the defined benefit liability and the return on plan assets (excluding amounts included in net interest on the net defined benefit liability), are recognised in the statement of financial position with a corresponding debit or credit to retained earnings through OCI in the period in which they occur. Remeasurements are not reclassified to the statement of profit or loss in subsequent periods.

The Group operates a defined benefit plan in India, viz., gratuity. The cost of providing benefit under this plan is determined on the basis of actuarial valuation at each period-end carried out using the projected unit cost method.

Net interest is calculated by applying the discount rate to the net defined benefit liability or asset. The Group recognises the following changes in the net defined benefit obligation as an expense in the statement of profit or loss:

- Service costs comprising current service costs, gains and losses on curtailments and non-routine settlements; and

- Net interest expense or income

Accumulated leave, which is expected to be utilised within the next twelve months, is treated as short term employee benefit. The Group measures the expected cost of such absences as an additional amount that it expects to pay as a result of the unused entitlement that has accumulated at reporting date.

The Group treats the accumulated leave expected to be carried forward beyond twelve months, as long term employee benefit for measurement purposes. Such long term compensated absences are determined on the basis of actuarial valuation at each period-end carried out using the projected unit cost method. Remeasurements comprising of actuarial gain and losses are recognised in the statement of financial position with a corresponding debit or credit to statement of profit or loss in the period in which they occur. The Group presents the leave as current liability in the balance sheet, to the extent it does not have an unconditional right to defer its settlement for 12 months after the reporting date. Where Group has unconditional legal and contractual right to defer the settlement for a period beyond 12 months, the same is presented as non-current liability.

Provisions

Provisions are recognised when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. When the Group expects some or all of a provision to be reimbursed, for example, under an insurance contract, the reimbursement is recognised as a separate asset, but only when the reimbursement is virtually certain. The expense relating to a provision is presented in the statement of profit or loss net of any reimbursement.

If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, when appropriate, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognised as a finance cost.

Decommissioning liability

The Group considers constructive obligations and records a provision for decommissioning costs of the wind and solar power plants. Decommissioning costs are provided for at the present value of expected costs to settle the obligation using estimated cash flows and are recognised as part of the cost of the relevant asset. The cash flows are discounted at a current pre-tax rate that reflects the risks specific to the decommissioning liability. The unwinding of the discount is expensed as incurred and recognised in the statement of profit or loss as a finance cost. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate. Changes in the estimated future costs, or in the discount rate applied, are added to or deducted from the cost of the asset.

Financial instruments

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

Financial assets

Initial recognition and measurement

Financial assets are classified, at initial recognition, as subsequently measured at amortised cost, fair value through other comprehensive income (FVTOCI), and fair value through profit or loss (FVTPL).

The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Group’s business model for managing them. With the exception of trade receivables that do not contain a significant financing component or for which the Group has applied the practical expedient, the Group initially measures a financial asset at its fair value plus, in the case of a financial asset not at FVTPL, transaction costs. Trade receivables that do not contain a significant financing component or for which the Group has applied the practical expedient are measured at the transaction price as disclosed in section 4.1(e).

Subsequent measurement

For purposes of subsequent measurement, financial assets are classified in four categories:

Debt instruments at amortised cost

A ‘debt instrument’ is measured at the amortised cost if both the following conditions are met:

The asset is held within a business model whose objective is to hold assets for collecting contractual cash flows; and

Contractual terms of the asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

After initial measurement, such financial assets are subsequently measured at amortised cost using the EIR method. Amortised cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortisation is included in other income in the statement of profit or loss. The losses arising from impairment are recognised in the statement of profit or loss.

Debt instruments at FVTPL

FVTPL is a residual category for debt instruments. Any debt instrument, which does not meet the criteria for categorisation as at amortised cost or as FVTOCI, is classified as at FVTPL.

In addition, the Group may elect to designate a debt instrument, which otherwise meets amortised cost or FVTOCI criteria, as at FVTPL. However, such election is allowed only if doing so reduces or eliminates a measurement or recognition inconsistency (referred to as ‘accounting mismatch’). The Group has not designated any debt instrument as at FVTPL.

Debt instruments included within FVTPL category are measured at fair value with all changes recognised in the statement of profit or loss.

Equity investments

All other equity investments in scope of IFRS 9 are measured at fair value. Equity instruments which are held for trading and contingent consideration recognised by an acquirer in a business combination to which IFRS 3 applies are classified at FVTPL. For all other equity instruments, the Group may make an irrevocable election to present in other comprehensive income subsequent changes in the fair value. The Group makes such election on an instrument-by-instrument basis. The classification is made on initial recognition and is irrevocable.

If the Group decides to classify an equity instrument as at FVTOCI, then all fair value changes on the instrument, excluding dividends, are recognised in the OCI. There is no recycling of the amounts from OCI to statement of profit or loss, even on sale of investment. However, the Group may transfer the cumulative gain or loss within equity.

Equity instruments included within FVTPL category are measured at fair value with all changes recognised in the statement of profit or loss. The Group has not designated any instrument at FVTOCI.

Embedded derivatives

A derivative embedded in a hybrid contract, with a financial liability or non-financial host, is separated from the host and accounted for as a separate derivative if: the economic characteristics and risks are not closely related to the host; a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and the hybrid contract is not measured at FVTPL. Embedded derivatives are measured at fair value with changes in fair value recognised in statement of profit or loss. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the FVTPL category.

Derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognised when:

- The rights to receive cash flows from the asset have expired.

Impairment of financial assets

In accordance with IFRS 9, the Group applies expected credit loss (ECL) model for measurement and recognition of impairment loss for all debt instruments not held at FVTPL. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Group expects to receive, discounted at an approximation of the original effective interest rate.

The Group follows 'simplified approach' for recognition of impairment loss allowance on trade receivables or contract revenue receivables. The Group has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment.

The application of simplified approach does not require the Group to track changes in credit risk. Rather it recognises impairment loss allowance based on lifetime ECLs at each reporting date, right from initial recognition.

For recognition of impairment loss on other financial assets and risk exposure, the group determines that whether there has been a significant increase in the credit risk since initial recognition. If credit risk has not increased significantly, 12-month ECL is used to provide for impairment loss. However, if credit risk has increased significantly, lifetime ECL is used. If, in a subsequent period, credit quality of the instrument improves such that there is no longer a significant increase in credit risk since initial recognition, then the entity reverts to recognising impairment loss allowance based on 12-month ECL. The Group considers that there has been a significant increase in credit risk when contractual payments are more than 30 days past due.

Lifetime ECL are the expected credit losses resulting from all possible default events over the expected life of a financial instrument. The 12-month ECL is a portion of the lifetime ECL which results from default events that are possible within 12 months after the reporting date.

The Group considers a financial asset in default when contractual payments are 90 days past due. However, in certain cases, the Group may also consider a financial asset to be in default when internal or external information indicates that the Group is unlikely to receive the outstanding contractual amounts in full before taking into account any credit enhancements held by the Group. A financial asset is written off when there is no reasonable expectation of recovering the contractual cash flows.

For financial guarantee contracts, the date that the Group becomes a party to the irrevocable commitment is considered to be the date of initial recognition for the purposes of assessing the financial instrument for impairment. In assessing whether there has been a significant increase in the credit risk since initial recognition of a financial guarantee contracts, the Group considers the changes in the risk that the specified debtor will default on the contract.

For a financial guarantee contract, as the Group is required to make payments only in the event of a default by the debtor in accordance with the terms of the instrument that is guaranteed, the expected loss allowance is the expected payments to reimburse the holder for a credit loss that it incurs less any amounts that the Group expects to receive from the holder, the debtor or any other party.

The Group regularly monitors the effectiveness of the criteria used to identify whether there has been a significant increase in credit risk and revises them as appropriate to ensure that the criteria are capable of identifying significant increase in credit risk before the amount becomes past due.

ECL impairment loss allowance (or reversal) during the period is recognised as income / expense in the statement of profit or loss.

Modification of contractual cash flows

When the contractual cash flows of a financial asset are renegotiated or otherwise modified and the renegotiation or modification does not result in the derecognition of that financial asset in accordance with IFRS 9, the Group recalculates the gross carrying amount of the financial asset and recognises a modification gain or loss under finance income or finance costs, respectively, in the statement of profit or loss. The gross carrying amount of the financial asset is recalculated as the present value of the renegotiated or modified contractual cash flows that are discounted at the financial asset’s original effective interest rate (or credit-adjusted effective interest rate for purchased or originated credit-impaired financial assets) or, when applicable, the revised effective interest rate calculated. Any costs or fees incurred are adjusted with the carrying amount of the modified financial asset and are amortised over the remaining term of the modified financial asset.

Financial liabilities

Initial recognition and measurement

Financial liabilities are classified, at initial recognition, as financial liabilities at FVTPL, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate. All financial liabilities are recognised initially at fair value and in the case of loans and borrowings and payables, net of directly attributable transaction costs. The financial liabilities of the Group include trade and other payables, derivative financial instruments, loans and borrowings including bank overdraft.

Subsequent measurement

The measurement of financial liabilities depends on their classification as discussed below:

Loans and borrowings

After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortised cost using the EIR method. Gains and losses are recognised in the statement of profit or loss when the liabilities are derecognised as well as through the EIR amortisation process.

Amortised cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortisation is included as finance costs in the statement of profit or loss. This category generally applies to borrowings.

Compound financial instruments

Compound financial instruments (CFIs) are separated into liability and equity components based on the terms of the contract.

The Group recognises interest, dividends, losses and gains relating to such financial instrument or a component that is a financial liability as income or expense in the statement of profit or loss.

The present value of the liability part of the compulsorily convertible debentures classified under financial liabilities and the equity component is calculated by subtracting the liability from the total proceeds of CFIs.

Transaction costs that relate to the issue of a compound financial instrument are allocated to the liability and equity components of the instrument in proportion to the allocation of proceeds. Transaction costs that relate jointly to more than one transaction (for example, cost of issue of debentures, listing fees) are allocated to those transactions using a basis of allocation that is rational and consistent with similar transactions.

Financial guarantees

Financial guarantee contracts issued by the group are those contracts that require a payment to be made to reimburse the holder for a loss it incurs because the specified debtor fails to make a payment when due in accordance with the terms of a debt instrument. Financial guarantee contracts are recognised initially as a liability at fair value, adjusted for transaction costs that are directly attributable to the issuance of the guarantee. Subsequently, the liability is measured at the higher of the amount of loss allowance determined as per impairment requirements of IFRS 9 and the amount recognised less, when appropriate, the cumulative amount of income recognised in accordance with the principles of IFRS 15.

Derecognition

A financial liability is derecognised when the obligation under the liability is discharged / cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognised in the statement of profit or loss.

Offsetting of financial instruments

Financial assets and financial liabilities are offset and the net amount is reported in the statement of financial position if there is a currently enforceable legal right to offset the recognised amounts and there is an intention to settle on a net basis, to realise the assets and settle the liabilities simultaneously.

Derivative financial instruments and hedge accounting

Initial recognition and subsequent measurement

The Group uses derivative financial instruments, such as foreign currency forward contracts, cross currency swaps (CCS), call spreads, foreign currency option contracts and interest rate swaps (IRS), to hedge its interest rate risks and foreign currency risks. Such derivative financial instruments are initially recognised at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

Any gains or losses arising from changes in the fair value of derivatives are taken directly to the statement of profit or loss, except for the effective portion of cash flow hedges, which is recognised in OCI and later reclassified to statement of profit or loss when the hedge item affects profit or loss or treated as basis adjustment if a hedged forecast transaction subsequently results in the recognition of a non-financial asset or non-financial liability.

For the purpose of hedge accounting, hedges are classified as:

- Fair value hedges when hedging the exposure to changes in the fair value of a recognised asset or liability or an unrecognised firm commitment

- Cash flow hedges when hedging the exposure to variability in cash flows that is either attributable to a particular risk associated with a recognised asset or liability or a highly probable forecast transaction or the foreign currency risk in an unrecognised firm commitment

At the inception of a hedge relationship, the Group formally designates and documents the hedge relationship to which the Group wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge.

The documentation includes identification of the hedging instrument, the hedged item, the nature of the risk being hedged and how the Group will assess whether the hedging relationship meets the hedge effectiveness requirements (including the analysis of sources of hedge ineffectiveness and how the hedge ratio is determined). A hedging relationship qualifies for hedge accounting if it meets all of the following effectiveness requirements:

•

There is ‘an economic relationship’ between the hedged item and the hedging instrument.

•

The effect of credit risk does not ‘dominate the value changes’ that result from that economic relationship.

•

The hedge ratio of the hedging relationship is the same as that resulting from the quantity of the hedged item that the Group actually hedges and the quantity of the hedging instrument that the Group actually uses to hedge that quantity of hedged item.

Hedges that meet the strict criteria for hedge accounting are accounted for, as described below:

Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is recognised in OCI in the cash flow hedge reserve, while any ineffective portion is recognised immediately in the statement of profit or loss. The cash flow hedge reserve is adjusted to the lower of the cumulative gain or loss on the hedging instrument and the cumulative change in fair value of the hedged item. The Group uses forward currency contracts as hedges of its exposure to foreign currency risk in forecast transactions and firm commitments. The ineffective portion relating to foreign currency contracts is recognised as other expense.

The Group designates only the spot element of forward contracts as a hedging instrument and the forward element is recognised in OCI and accumulated in seperate component of equity under the cost of hedge reserve. The amounts accumulated in OCI are accounted for, depending on the nature of the underlying hedged transaction. If the hedged transaction subsequently results in the recognition of a non-financial item, the amount accumulated in equity is removed from the separate component of equity and included in the initial cost or other carrying amount of the hedged asset or liability. This is not a reclassification adjustment and will not be recognised in OCI for the period. This also applies where the hedged forecast transaction of a non-financial asset or non-financial liability subsequently becomes a firm commitment for which fair value hedge accounting is applied.

When option contracts are used, the Group uses only intrinsic value of the option as the hedging instrument. Gains or losses relating to the effective portion of the changes in intrinsic value of the option are recognised in the cash flow hedging reserve within equity. The changes in the time value of money that relate to the hedged item are recognised within other comprehensive income in the cost of hedging reserve within equity.

For any other cash flow hedges, the amount accumulated in OCI is reclassified to the statement of profit or loss as a reclassification adjustment in the same period or periods during which the hedged cash flows affect profit or loss.

If cash flow hedge accounting is discontinued, the amount that has been accumulated in OCI must remain in accumulated OCI if the hedged future cash flows are still expected to occur. Otherwise, the amount will be immediately reclassified to the statement of profit or loss as a reclassification adjustment. After discontinuation, once the hedged cash flow occurs, any amount remaining in accumulated OCI must be accounted for depending on the nature of the underlying transaction as described above.

Cash and bank balances

(i)

Cash and cash-equivalents

Cash and short-term deposits in the statement of financial position comprise cash at banks and cash in hand and short-term deposits with an original maturity of three months or less, that are readily convertible to a known amount of cash and subject to an insignificant risk of changes in value. For the purpose of the statement of cash flows, cash and cash equivalents consist of cash and short term deposits, as defined above, net of bank overdrafts as they are considered an integral part of the Group's cash management.

(ii)

Bank balances other than cash and cash equivalents

Bank balances other than cash and cash equivalents consists of deposits with an original maturity of more than three months. These balances are classified into current and non-current portions based on the remaining term of the deposit.

Contingent liabilities

Contingent liabilities are disclosed when there is a possible obligation arising from past events, the existence of which will be confirmed only by the occurrence or non-occurrence of one or more uncertain future events not wholly within the control of the Group or a present obligation that arises from past events where it is either not probable that an outflow of resources will be required to settle or a reliable estimate of the amount cannot be made.

Earnings per equity share (EPS)

Basic earnings per equity share is computed by dividing the net profit attributable to the equity holders of the Parent by the weighted average number of equity shares and instruments mandatorily convertible into equity shares outstanding during the period. Diluted earnings per equity share is computed by dividing the net profit attributable to the equity holders of the Group by the weighted average number of

equity shares considered for deriving basic earnings per equity share and also the weighted average number of equity shares that could have been issued upon conversion of all dilutive potential equity shares.

The dilutive potential equity shares are adjusted for the proceeds receivable had the equity shares been actually issued at fair value (i.e. the average market value of the outstanding equity shares). Dilutive potential equity shares are deemed converted as of the beginning of the period, unless issued at a later date. Dilutive potential equity shares are determined independently for each period presented.

The number of equity shares and potentially dilutive equity shares are adjusted retrospectively for all periods presented for any share splits and bonus shares issues including for changes effected prior to the approval of the consolidated financial statements by the Board of Directors. The dilutive effect of outstanding options is reflected as additional share dilution in the computation of diluted earnings per share.

Non-current assets (and disposal groups) classified as held for sale

The Group classifies non-current assets and disposal groups as held for sale if their carrying amounts will be recovered principally through a sale transaction rather than through continuing use. Non-current assets and disposal groups classified as held for sale are measured at the lower of their carrying amount and fair value less costs to sell. Costs to sell are the incremental costs directly attributable to the disposal of an asset (disposal group), excluding finance costs and income tax expense.

The criteria for held for sale classification is regarded as met only when the sale is highly probable, and the asset or disposal group is available for immediate sale in its present condition. Actions required to complete the sale should indicate that it is unlikely that significant changes to the sale will be made or that the decision to sell will be withdrawn. Management must be committed to the plan to sell the asset and the sale expected to be completed within one year from the date of the classification.

Property, plant and equipment, intangible assets and right of use assets are not depreciated or amortised once classified as held for sale.

Assets and liabilities classified as held for sale are presented separately as current items in the statement of financial position.

Immediately prior to classification as held for sale, the assets or groups of assets were remeasured in accordance with the Group’s accounting policies. Subsequently, assets and disposal groups classified as held for sale were valued at the lower of book value or fair value less disposal costs. A gain or loss not previously recognised by the date of sale of non-current assets (or disposal group) is recognised at the date of de-recognition.

Treasury shares

Own equity instruments that are reacquired (treasury shares) are recognised at cost and deducted from retained earnings. No gain or loss is recognised in the statement of profit or loss on the purchase, sale, issue or cancellation of the Group’s own equity instruments. At the time of re-issue, any difference between the carrying amount and the consideration is recognised as share premium.

4.2.

New standards, interpretations and amendments

4.2.1.

New and amended standards and interpretations adopted by the Group

The Group applied for the first-time certain standards and amendments, which are effective for annual periods beginning April 1, 2023 but do not have a material impact on the consolidated financial statements of the Group. The Group has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective.

(a)

Amendments to IAS 12 - Deferred Tax related to Assets and Liabilities arising from a Single Transaction

The amendments to IAS 12 - Income tax narrow the scope of the initial recognition exception under IAS 12, so that it no longer applies to transactions that give rise to equal taxable and deductible temporary differences such as leases.

The amendment had no impact on the Group's consolidated financial statements.

(b)

Amendments to IAS 1 and IFRS Practice Statement 2 - Disclosure of Accounting Policies

The amendments require entities to provide accounting policy disclosures that are more useful by replacing the requirement for entities to disclose their ‘significant’ accounting policies with a requirement to disclose their ‘material’ accounting policies and adding guidance on how entities apply the concept of materiality in making decisions about accounting policy disclosures.

The amendments have had an impact on the Group’s disclosures of accounting policies, but not on the measurement, recognition or presentation of any items in the Group’s financial statements.

(c)

Amendments to IAS 8- Definition of Accounting Estimates

The amendments clarify the distinction between changes in accounting estimates, changes in accounting policies and the correction of errors. It has also been clarified how entities use measurement techniques and inputs to develop accounting estimates.

The amendments had no impact on the Group’s consolidated financial statements.

4.2.2.

Standards issued but not yet effective

The following new and amended standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Group’s financial statements are disclosed below. The Group intends to adopt these new and amended standards and interpretations, if applicable, when they become effective.

- Amendments to IAS 1 - Classification of Liabilities as Current or Non-current (effective from January 1, 2024*#)

- Amendments to IAS 7 and IFRS 7 - Supplier Finance Arrangements (effective from January 1, 2024*#)

- Amendments to IFRS 9 and IFRS 7 - Amendments to the classification and measurement of financial instruments (effective from January 1, 2026*#)

Replacement of Group Stock Option Plans

On August 23, 2021, all vested and unvested options outstanding for Group Stock Option Plans were replaced by the ‘2021 Stock Entitlement Program’ of the Company (Holding Company Stock Option Plans) with similar terms as per the original options. The employees of the Group were entitled to 0.8289 Holding Company Stock Option for every one Group Stock Option held for both vested and unvested options with no changes in vesting period and exercise period. The exercise price of Group Stock Option, which was fixed in INR, got converted into US Dollars using exchange rate as on the date of replacement, as exercise price of Holding Company Stock Option.

The Holding Company Stock Option Plans granted to the employees will be settled in Class A share of the Company. Therefore, the Holding Company Stock Option Plans have been classified as an equity settled share based payment. The replacement of Group Stock Option Plans with Holding Company Stock Option Plans is identified as replacement plan and accounted for as a modification of the Group Stock Option Plans. ESOP expenses [grant date fair value as per Group Stock Option Plans plus incremental fair value (if any) measured at the date of replacement] related to employees of the Group are recognised as employees’ expenses, over vesting period. The modification reduces the fair value of the stock options granted, measured immediately before and after the modification, and therefore the Group has not taken into account that decrease in fair value and had continued to measure the amount recognised for services received based on the grant date fair value of the Group Stock Option Plans granted. Pursuant to replacement of stock options, on the date of replacement, 6,933,865 vested and 7,146,270 unvested option of Group Stock Option Plans got replaced with 5,747,481 vested and 5,923,543 unvested Holding Company Stock Option Plans.


Particulars	Group Stock Option Plans	Holding Company Stock Option Plans
Dividend yield (%)	0.0%	0.0%
Expected volatility (%)	25.67% - 37.87%	33.43% - 49.97%
Risk–free interest rate (%)	3.29% - 6.39%	0.05% - 1.03%
Weighted average expected life of options granted	0.07 years - 6.86 years	0.07 years - 6.86 years
Weighted average share price	INR 606.96	USD 8.17

The expected volatility reflects the assumption that the historical volatility over a period similar to the life of the options is indicative of future trends, which may not necessarily be the actual outcome.

The relevant terms of the Holding Company Stock Option Plans are as below:

Disclosure Of Basis Of Preparation [Abstract]

Basis of preparation

The consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). The Group has prepared the conslidated financial statements on the basis that it will continue to operate as a going concern. The Directors consider that there are no material uncertainties that may cast significant doubt over this assumption. They have formed a judgement that there is a reasonable expectation that the Group has adequate resources to continue in operational existence for the foreseeable future, and not less than 12 months from the end of the reporting period.

These consolidated financial statements have been prepared in accordance with the accounting policies, set out below, and were in all material aspects were consistently applied to all periods presented unless otherwise stated (refer Note 2.4). Refer Note 4.2.1 for new and amended standards and interpretations adopted by the Group.

The consolidated financial statements have been prepared on a historical cost basis, except for the following assets and liabilities which have been measured at fair value:

- Financial assets and liabilities measured at fair value (refer accounting policy regarding financial instruments)

- Equity-settled share based payments measured at fair value on grant date

- Share warrants

- Liability for put options with non-controlling interests (refer accounting policy below)

2.2 Convenience translation (unaudited)

The consolidated financial statements are presented in Indian Rupee (INR), the presentation currency of the Group. Solely for the convenience of readers, the consolidated financial statements as at and for the year ended March 31, 2024 have been translated to U.S. Dollars (USD) at the exchange rate of INR 83.34 per USD 1.00, being the noon buying rate in New York City for cable transfer in non-U.S. currencies as certified for customs purposes by the Federal Reserve Bank of New York on March 31, 2024.

No representation is made that the Indian rupee amounts have been, could have been or could be converted into USD at such a rate or any other rate. Such convenience translation is not subject to audit by the Company’s Independent Registered Public Accounting Firm.

2.3 Accounting policy for transaction referred in Note 1:

On completion of the Transaction referred in Note 1, the former shareholders of RPL become majority shareholders of the Company and have the ability to elect, appoint or remove a majority of the members of the governing body of the Company. There were no material assets or liabilities or operations in the Company prior to this transaction. RMG II is a non-operating entity that does not meet the definition of a business under IFRS 3 - Business combination. Therefore, for accounting purposes, RPL is deemed to be the accounting acquirer in the transaction. The transaction has been treated as a capital transaction equivalent to the issue of shares of RPL in exchange for the net monetary assets acquired and therefore, acquisition accounting does not apply.

Consequently, there was no goodwill or other intangible assets recorded, in accordance with IFRS. Any difference in the fair value of the shares deemed to have been issued by the accounting acquirer and the fair value of the accounting acquiree‘s identifiable net assets is considered to be payment for a service of a stock exchange listing and recognised as expenses under head “Listing and related expenses” in consolidated statement of profit or loss.

The consolidated financial statements of the Group represent the continuation of the pre-acquisition consolidated financial statements of RPL. The consolidated financial statements of the Group reflect:

(a) the assets and liabilities of the accounting acquirer recognised and measured at their pre-combination carrying amounts;

(b) the retained earnings and other equity balances of the accounting acquirer before this transaction, after adjusting amount attributable to non-controlling interest ('NCI') recognised;

(c) the amount recognised as issued capital and share premium is determined by adding the issued equity of the accounting acquirer outstanding immediately before the Transaction, after adjusting amount attributable to NCI recognised to the fair value consideration effectively transferred. The number and type of equity instruments pre-acquisition reflect the equity structure of RPL. Post the Transaction, the number and type of equity instruments issued, reflects the equity structure of the Company. Refer Note 34 for adjustment carried to number of equity instruments for computation of earnings per share.

(d) the non-controlling interest’s proportionate share of the accounting acquirer’s pre-combination carrying amounts of retained earnings and other equity interests;

(e) the statement of profit or loss and other comprehensive income for the current period reflects that of the accounting acquirer for the full period together with the post-acquisition results of the accounting acquiree.

The consolidated financial statements for the period April 1, 2021 to August 23, 2021 include financial data pertaining only to RPL and its subsidiaries.

2. 4 Changes in presentation and disclosures

(a) The portion of the long-term interest-bearing loans and borrowings and interest accrued on borrowings, which was falling due for repayment within 12 months from the reporting date was previously being included and presented as part of ‘Current- other financial liabilities'. The Group has reassessed the presentation and disclosures of these items and concluded that including and presenting such liabilities as part of ‘Current- interest-bearing loans and borrowings’, which is also a part of the 'Current liabilities', would lead to a better presentation and understanding of the consolidated financial statements. Accordingly, the Group has included the portion of long-term interest bearing loans and borrowings and interest accrued on borrowings, which is falling due for repayment within 12 months from the reporting date, aggregating to INR 29,803 as at March 31, 2024 (March 31, 2023: INR 20,591; April 1, 2022: INR 56,046) under ‘short-term interest bearing loans and borrowings’ instead of ‘Other financial liabilities’, both of which are part of the main heading ‘Current liabilities’ and are financial liabilities.

(b) Besides the above, the management has re-evaluated presentation of certain items on the face of the consolidated financial statements and in notes, basis materiality considerations. Basis re-evaluation, it has presented certain items with relatively smaller amounts in notes instead of the face of the consolidated financial statement and certain items with immaterial amounts have been grouped in the notes under the same heading. The management believes these changes will help in reducing the information overload and improve the overall understanding of the consolidated financial statements, without obscuring any material information.

Since, both the above changes relate only to presentation and disclosures, they do not impact recognition and measurement of any of the items in the consolidated financial statements, and, consequentially, there is no impact on total equity and/ or profit / (loss) for the current or any of the earlier periods. Nor there is any impact on presentation of consolidated cash flow statement. All the changes pertain to change in line item/ grouping of immaterial items under the same sub-heading. Considering the nature of changes, the management believes that they do not have any material impact on the consolidated statement of financial position at the beginning of the comparative period and, therefore, there is no need for separate presentation of an additiional consolidated statement of financial position.

2. 5 Significant accounting judgments, estimates and assumptions

The preparation of consolidated financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities and the accompanying disclosures. Uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods.

In the process of applying the accounting policies management has made certain judgments, estimates and assumptions. The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Group based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising that are beyond control of the Group. Such changes are reflected in assumptions when they occur.

Estimates and assumptions

a) Impairment of goodwill for Ostro group of CGUs

The key assumptions used to determine the recoverable amount for the different CGUs or group of CGUs including the Ostro Group of CGUs where goodwill has been allocated are disclosed and further explained in Note 6. The impairment assessments are based on a range of estimates and assumptions, including future estimates of revenues, costs and discount rates as more fully described in the said Note 6.

Significant accounting judgements

Note 53(a) below describes accounting judgements applied with respect to the contracts entered for transmission projects under the Build, Own, Operate and Maintain (BOOM) model, where there has been a change of law in the current year.

2. 6 The consolidated financial statements are presented in Indian Rupees (INR) and all values are rounded to the nearest million, except when otherwise indicated. Absolute amounts less than INR 500,000 are appearing as "0" due to presentation in millions.

(i) Number of shares presented represents RPL Shares. Equivalent number of equity instruments of the Company will be number of RPL shares presented multiplied by exchange ratio established in the Transaction referred in Note 1 (i.e., 1 RPL share to 0.8289 Company Share).

(ii) During the year ended March 31, 2022, Series A compulsory convertible preference shares issued to certain existing shareholders were converted into equity shares on August 23, 2021 as per its original terms. Consequently, amortised cost of compulsory convertible preference shares of INR 27,665 which was classified as financial liability on the date of conversion was derecognised with recognition of issued capital amounting to INR 445 and share premium of INR 27,220.

(iii) Number of shares presented represents shares issued by the Company for the Transaction. Deemed number of shares issued by RPL is 127,381,626. Amount recognised in issued capital and share premium represents fair value consideration effectively transferred by RPL.

(iv) Number of shares presented represents Company's shares outstanding on consummation of the Transaction.

(v) During the year ended March 31, 2022, the Company has issued class C shares on purchase of shares held by non-controlling interests in RPL. (refer Note 51(a))

(vi) Before consummation of the Transaction, the Company had 1 equity share at par value of USD 0.01.

*Capital Reduction and Share Repurchase Program

Pursuant to a court order dated February 8, 2022, the Company’s share premium account was cancelled and the amount of INR 9,128 standing to its credit was transferred to the Company’s retained earnings account with effect from February 14, 2022.

On February 2, 2022, the Company’s Board of Directors approved the Company’s proposal to commence a share repurchase program of up to USD 250 worth of its Class A Ordinary Shares (the “Share Repurchase Program”) by way of open market purchases and the

Company engaged Credit Suisse Securities (USA) LLC and Mizuho Securities USA LLC as its brokers (the Brokers) for the Share Repurchase Program.

During the year ended March 31, 2024, the Brokers purchased 10,688,015 Class A Ordinary Shares (par value USD 0.0001 each) from the open market for the purpose of the Share Repurchase Program for a consideration equivalent to INR 4,926 (March 31, 2023: 26,354,973 Class A Ordinary Shares for a consideration equivalent of INR 13,499). All the foregoing shares (including the 1,655,300 which were held pending cancellation as of March 31, 2022) were repurchased into treasury by the Company. Consequently, the retained earnings account has been reduced by INR 4,926 (March 31, 2023: INR 13,499).

As at March 31, 2024, 38,698,288 shares (March 31, 2023: 28,010,273) have been repurchased.

Terms / rights attached to equity shares of RPL

RPL has only one class of equity shares having par value of INR 10 per share. Each holder of equity shares is entitled to one vote per share. If declared, the Group will declare and pay dividends in Indian rupees. In the event of liquidation of a Group, the holders of equity shares of such Group will be entitled to receive remaining assets of the Group, after distribution of all preferential amounts. The distribution will be in proportion to the number of equity shares held by the shareholders of the Group.

The equity shares were redeemable at the option of the holders till August 23, 2021 and therefore, were considered a puttable instrument in accordance with IAS 32. Puttable instruments are required to be accounted for as financial liabilities, except where certain conditions are met in accordance with IAS 32, in which case, the puttable instruments may be presented as equity. The equity shares meet the conditions of IAS 32 and are, therefore, classified and accounted for as equity. Pursuant to the BCA (refer Note 1), the Company became legal parent of RPL. Post this transaction, the number and type of equity instruments issued, reflects the equity structure of the Company.

Modification of contractual cash flows

The Ministry of Power in its Gazette Notification dated June 3, 2022, established rules providing settlement mechanism for the amounts owed by generating companies, inter-state transmission licensees and electricity trading licensees.

The Group's customers subject to this scheme shall pay the outstanding receivables due to the Group in equated monthly instalments without interest. Accordingly, the Group has recorded the modification in terms of the contract and the resultant loss primarily due to the extended interest free credit period has been recognised as a finance cost in the statement of profit or loss.

Unwinding income on these trade receivables of INR 504 (March 31, 2023: INR 441) is recognised as "Unwinding income of financial assets" under 'Finance income'. Trade receivables outstanding of INR 1,664 as at March 31, 2024 (March 31, 2023: INR 3,671) , from customers opting for EMI pursuant to LPS Rules, which are not due within the next twelve months from the end of the reporting date, are disclosed as non-current.

Others (solar power segment)*		364		364

* includes amount allocated against multiple group of CGUs and the amount allocated to each group of CGU is not material.

The Group undertook the impairment testing of Goodwill assigned to each Individual or Group of CGUs as at March 31, 2024 and 2023 by applying the Value in Use ('VIU') approach. The Group has entered into Power Purchase Agreements (PPA) upto 25 years which

entitles the Group to a fixed tariff over the tenure of PPAs. Accordingly, the Group for computing the VIU has determined cash flow projections based on fixed tariffs as specified in the PPAs upto the remaining tenure of PPAs and for periods thereafter, the Group has used forecasted tariffs based on assessment provided by an external specialist. The key assumptions used in computation of VIU are the Plant Load Factor (PLF), a measure of average capacity utilisation of a power plant, used in revenue projections, future operating and maintenance expenses and discount rates.

The PLF is determined based on forecasts after considering study of future wind speed (only for wind segment) and past performance; operation and maintenance expenses are based on prevaling prices and quotations received (adjusted for inflation) together with business plans; and discount rates are based on weighted average cost of capital. These assumptions are forward-looking and are affected by future economic and climatic conditions including wind speed.

Based on the results of the impairment test, the estimated value in use of each Group of CGU and individual CGU was more than their respective carrying values, by the following amounts:


	As at March 31,
Group of CGU / individual CGU	2024		2023
Ostro Energy Group (wind power segment)1		2,050		583
ReNew Vayu Urja (wind power segment)2		1,185		1,831
Prathamesh Solarfarms (solar power segment)3		685		964
Others (wind power segment)2		2,318		1,706
Others (solar power segment)3		911		1,844

(1) The Group has engaged external specialists to assist in determining (a) future PLFs and (b) discount rates and computation of VIU. The Group has currently estimated a discount rate of 12.12% (March 31, 2023: 11.32%; March 31, 2022: 11.20%), PLF of 26.27% (March 31, 2023: 26.27%; March 31, 2022: 27.76%) and future operating and maintenance costs of INR 0.75 million per MW (March 31, 2023: INR 0.75 million per MW; March 31, 2022: INR 0.7 million per MW) adjusted for future inflation. Increase in discount rate by 0.38% per annum (March 31, 2023: 0.11% per annum) or decrease in PLF by 0.62% (March 31, 2023: 0.18% per annum) or increase in future operating and maintenance expenses by 28.93% per annum (March 31, 2023: 8% per annum), would result in value in use to be equal to the carrying amount.

(2) The Group has currently estimated discount rates ranging between 11.43% to 13.09% (March 31, 2023: 10.55% to 12.38%;March 31, 2022: 11.05% to 12.34%), PLF of 22.50% to 31.70% (March 31, 2023: 22.50% to 31.70%; March 31, 2022: 22.97% to 32.82%) and future operating and maintenance costs of INR 0.75 million per MW (March 31, 2023: INR 0.75 million per MW; March 31, 2022: INR 0.70 million per MW) adjusted for future inflation. The Management believes that any reasonably possible change in the key assumptions on which value in use is based would not cause the aggregate carrying amount of each group of CGU and individual CGU to exceed the aggregate value in use.

(3) The Group has currently estimated discount rates ranging between 11.74% to 13.52% (March 31, 2023: 10.68% to 11.51%; March 31, 2022: 10.29% to 10.97%), PLF of 18.13% to 24.62% (March 31, 2023: 18.13% to 24.62%; March 31, 2022: 16.42% to 29.51%) and future operating and maintenance costs of INR 0.50 million per MW (March 31, 2023: INR 0.50 million per MW; March 31, 2022: INR 0.47 million per MW) adjusted for future inflation. The Management believes that any reasonably possible change in the key assumptions on which value in use is based would not cause the aggregate carrying amount of each group of CGU and individual CGU to exceed the aggregate value in use.

Dispute with Southern Power Distribution Company of Andhra Pradesh Limited

Certain subsidiary companies (AP entities) have entered into long-term PPAs having a cumulative capacity of 777 MWs (wind and solar energy projects) with Southern Power Distribution Company of Andhra Pradesh Limited i.e. the distribution company of Andhra Pradesh (APDISCOM). These PPAs have a fixed rate per unit of electricity for the 25-year term. With regard to aforementioned PPAs, certain litigations as described below are currently underway:

1. In terms of the Generation Based Incentive (GBI) scheme of the Ministry of Renewable Energy (MNRE), the AP entities accrue income based on units of power supplied under the aforementioned PPAs. Andhra Pradesh Electricity Regulatory Commission (APERC) vide its order in July 2018 allowed APDISCOMS to interpret the Andhra Pradesh Electricity Regulatory Commission (Terms and Conditions for Tariff Determination for Wind Power Projects) Regulations, 2015 (Regulations) in a manner to treat GBI as a pass through in the tariff.

The AP entities filed writ petition before the Andhra Pradesh High Court (AP High Court) challenging the vires of the regulation and the order by APERC and were granted an interim stay order in August 2018 thereby directing APDISCOM not to deduct GBI from future billings from date of the order. As at March 31, 2024, the cumulative amount recoverable from the APDISCOM included in trade receivables amounts to INR 4,598 (March 31, 2023: INR 3,975 million).

The management, basis its assessment and the practice followed consistently in other states, believes that the GBI benefit is over and above the applicable tariffs and the APERC does not have jurisdiction to interfere with the intent of GBI scheme. Therefore the outstanding amount is recoverable and continues to be recognised in the consolidated financial statements.

2. The Government of Andhra Pradesh (GoAP) issued an order (GO) dated July 1, 2019 constituting a High-Level Negotiation Committee (HLNC) for review and negotiation of tariff for wind and solar energy projects in the state of Andhra Pradesh. Pursuant to the GO, APDISCOM issued letters dated July 11, 2019 and July 12, 2019 to the AP entities, requesting for revision of tariffs as agreed in the PPAs. The AP entities filed a writ petition on July 23, 2019 before the AP High Court challenging the GO and the said letters issued by APDISCOM for renegotiation of tariffs. The AP High Court issued its order dated September 24, 2019 ruled as follows:

i. Writ petition is allowed, and both GO and the subsequent letters are set aside.

ii. Further, APDISCOM were instructed to honor pending and future bills and pay the same at the interim rate of INR 2.43 per unit till determination of Original Petition (O.P.) No. 17 of 2018 pending before APERC

iii. APERC to dispose-off the case within a time frame of six months.

The AP Entities filed a Writ Appeal before the division bench of the AP High Court challenging the jurisdiction of APERC in entertaining O.P. No. 17 of 2018. Parallelly, the AP Entities filed another Writ Appeal before the division bench of the AP High Court challenging AP High Court’s direction to the APDISCOM to pay tariff at interim rate till determination of OP No. 17 of 2018 by APERC.

Thereafter, by its final order dated March 15, 2022, the AP High Court disposed off common batch matters and allowed the appeals by AP entities and set aside the Order dated September 24, 2019, holding that APERC does not have the jurisdiction to entertain Original Petition (O.P.) No. 17 of 2018 and directing APDISCOM to pay all outstanding amounts to AP entities within a period of 6 weeks.

APDISCOM filed petitions before the Supreme Court seeking special leave to appeal against the AP High Court's order dated March 15, 2022. The Supreme Court by its Order dated December 14, 2022, has issued notice to the respondents in one of the petitions viz. jurisdiction of the APERC to entertain OP 17 of 2019. The APDISCOM petition before Supreme Court is pending for final adjudication. As at March 31, 2024, the cumulative amount recoverable from the APDISCOM in relation to this matter included in trade receivables amounts to INR 3,064 (March 31, 2023: INR 2,305 million).

In view of the favourable order by the AP High Court and basis the internal anaylsis, management believes that it has strong merits in the case and no additional adjustment is required in the consolidated financial statements.

Dispute with Karnataka Electricity Regulatory Commission

ReNew Wind Energy (Karnataka) Private Limited and ReNew Wind Energy (AP) Private Limited, subsidiaries of the Group, set up projects to supply electricity for captive use by their shareholders. The KERC, through a circular dated September 18, 2018, directed the Karnataka Electricity Supply Companies ('KESCOMs') and Karnataka Power Transmission Corporation Limited to monitor the status of group captive generators/ consumers to ensure that they have acquired the status of group captive generators/ consumers and to verify the compliance of their consumption of electricity with the Electricity Rules, 2005, and to levy cross subsidy surcharge ('CSS') and electricity tax differential on captive users drawing power from captive generating plants in case of any violation. Pursuant to and basis the September 18, 2018 circular, Electricity Supply Companies ('ESCOMs') issued demand letters to the captive users of the Company’s subsidiaries specified above, seeking recovery of cross subsidy surcharge and differential of applicable electricity tax due to failure of compliance with the Electricity Rules, 2005. The Group filed writ petitions challenging the circular and the demand letters and against the ESCOMs (“Karnataka Writs”) and separate petitions before the KERC for quashing the demand letters (“Karnataka Petitions”).

The Karnataka High Court, in its interim orders dated July 18, 2019, and September 18, 2020, ordered the KESCOMs to refrain from taking any precipitative action against captive users. Thereafter, the KERC disposed of the Karnataka petitions based on the principles laid down by the Appellate Tribunal For Electricity ('APTEL') in its judgment dated June 7, 2021, in the case of Tamil Nadu Power Producers Association vs. Tamil Nadu Electricity Regulatory Commission and others. KERC declared that the plant maintained its compliance as a captive generating plant for FY 2017-18, except for FY 2013-14 and FY 2015-16.

On October 9, 2023, the Supreme Court notified its judgment in Civil Appeal Nos. 8527-8529 of 2009 in the matter of M/s Dakshin Gujarat Vij Company Limited, upholding the test of proportionality on a Special Purpose Vehicle (SPV), which was otherwise exempted, and reversing the judgment in the case of Tamil Nadu Power Producers Association vs. Tamil Nadu Electricity Regulatory Commission and others.

In December 2023, the KESCOMs challenged the KERC order before the APTEL, which is pending final adjudication.

The Group has also filed a Writ Petition before Karnataka High Court challenging the levy of CSS, since the levy was intended to be a temporary provision and were supposed to be reduced progressively in subsequent years. The Group believes that since there was no levy of cross-subsidy surcharge since FY 2009-2012, it cannot be re-introduced as per the intent of the Act.

The pleadings are completed and the matter is listed for final arguments. Further, the responsibility of drawing power in proportion to the shareholding was squarely on the consumers and hence as per the PPAs, it cannot be recovered from the Group. Neither a demand has been received till date nor does the Group expect any material demand in future.

Basis internal evaluation, management believes that there are merits in its position and that the demand raised by distribution companies would be utimately rescinded and hence no adjustment has been made in the consolidated financial statements in this regard.

The Group based on profit projections supported by existing PPAs and underlying contractual agreements believes that the utlisation of entire deferred tax assets is probable. All items of deferred tax assets have an infinite life except for those on tax losses and MAT which can be carried forward for a maximum period 8 years and 15 years, respectively, from the date of their origination. The Group based on its current profit projections expects to realise the deferred tax asset recognised on tax losses and MAT in their respective permissible carried forward periods. Additionally, the Group has performed sensitivities by reducing revenues and profits by 10% and noted that there was no material impact on recoverability of the recognised deferred tax assets.

The Group has tax losses amounting to INR 17,538 (March 31, 2023: INR 9,052) having an expiry period of 1 to 8 years (March 31, 2023: 1 to 8 years), capital losses amounting to INR Nil (March 31, 2023: INR 828) having Nil expiry period (March 31, 2023: 6 years), unabsorbed depreciation amounting to INR 5,187 (March 31, 2023: INR 5,917) which are available for utilisation indefinitely and MAT credit amounting to INR 229 (March 31, 2023: INR 213) having an expiry period of 8 to 15 years (March 31, 2023: 6 to 15 years) on which deferred tax assets have not been recognised as there may not be sufficient taxable profits to offset these losses.

Certain subsidiaries of the Group have undistributed earnings which, if paid out as dividends, would be subject to tax in the hands of recipient. An assessable temporary difference exists, but no deferred tax liability has been recognised as the Parent is able to control timing of distributions from these subsidiaries. The Parent is not expected to distribute these profits from the subsidiaries in the foreseeable future and no material tax charge is expected whenever distribution occurs.

12E There are additional disallowances / additions to returned income of RPL in earlier years on account of share based payment expenses, interest expense and few other disallowances.The management based on past legal precedents and the views of tax specialists believes that it has strong grounds on merit for successful appeal in this matter. The total exposure on the Group on account of such disallowances is INR 1,675 (March 31, 2023: INR 1,675) plus applicable interest till the settlement of such disputes. Further, the management based on past legal precedents and the views of tax specialists also believes that no penalty can be levied on such issue.

Others		359		136		348		4
Total		59,349		78,223		81,319		976

The above revenue includes (a) revenue from contract with customers of INR 81,097 (March 31, 2023: INR 78,223, March 31, 2022: INR 59,349) and (b) operating lease income of INR 222 (March 31, 2023 and 2022: INR Nil) which is a part of transmission line project.

The Group recognised impairment losses on receivables arising from contracts with customers, included under other expenses in the consolidated statement of profit or loss, amounting to INR 1,001 (March 31, 2023: INR 163, March 31, 2022: INR 404).

The location for all of the revenue from contracts with customers is India.

The timing for all of the revenue from contracts with customers is over time.

'The Group has certain power purchase agreements entered with customers which contains provision for claiming cost over-runs due to change in law clause, subject to approval by appropriate authority. During the year ended March 31, 2024, on receipt of approval of cost over-run of INR Nil (March 31, 2023: INR 641 , March 31, 2022: INR Nil), the Group has included the same as part of transaction price. Pending approval of cost over-runs of INR 3,578 (March 31, 2023: INR 3,578, March 31, 2022: INR 4,219) till the reporting period end, the Group has not included these over-runs as part of transaction price applying guidance on constraining estimates of variable consideration. Out of cost over-runs approved till the reporting period end, the Group during the year ended March 31, 2024 has recognised revenue of INR 110 (March 31, 2023: INR 321, March 31, 2022: INR 61).

Transaction price - remaining performance obligations

'The remaining performance obligation disclosure provides the aggregate amount of the transaction price yet to be recognised as at the end of the reporting period and an explanation as to when the Group expects to recognise these amounts in revenue. Applying the practical expedient as given in IFRS 15, the Group has not disclosed the remaining performance obligation related disclosures for contracts as the revenue recognised corresponds directly with the value to the customer of the entity’s performance completed to date, except to the extent stated in Note 53. The cost over-runs which are pending approval of customers have been excluded for this disclosure because these were not included in the transaction price. These cost over-runs were excluded from the transaction price in accordance with the guidance on constraining estimates of variable consideration.
