Disclosure Of Basis Of Preparation [Abstract]
Basis of preparation and changes to the Group's accounting policies	2. Basis of preparation and changes to the Group's accounting policies 2.1. 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 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 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) - Share based payments - Share warrants - Liability for put options (refer accounting policy below) 2.2. Convenience translation (unaudited) The consolidated financial statements are presented in Indian Rupee (INR), the presentation currency of the Company. Solely for the convenience of readers, the consolidated financial statements as at and for the year ended March 31, 2023 have been translated to U.S. Dollars (USD) at the exchange rate of INR 82.19 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, 2023. 2.3. Accounting policy for transaction referred in Note 1: On completion of transaction referred in Note 1, the former shareholders of RPPL 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. Therefore, for accounting purposes, RPPL 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 RPPL 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 statement of profit or loss. The consolidated financial statements of the Company represent the continuation of the pre-acquisition consolidated financial statements of RPPL. The consolidated financial statements of the Company 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 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 this 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 RPPL. Post this transaction, the number and type of equity instruments issued, reflects the equity structure of the Company. Refer Note 39 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 year ended March 31, 2021 and consolidated financial statements for the period April 1, 2021 to August 23, 2021 include financial data pertaining only to RPPL and its subsidiaries. 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.

Basis Of Consolidation [Abstract]
Basis of consolidation	3. Basis of consolidation The consolidated financial statements comprise the financial statements of the Company and its subsidiaries as at March 31, 2023. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, 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. Profit or loss and each component of OCI are attributed to the equity holders of the parent of the Group and to the non-controlling interests, even if this results in the non-controlling interests having a deficit balance. The consolidated financial statements are prepared using uniform accounting policies for like transactions and other events in similar circumstances. If a member of the Group uses accounting policies other than those adopted in the Consolidated Financial Statements for like transactions and events in similar circumstances, appropriate adjustments are made to that Group member’s financial statements in preparing the consolidated financial statements to ensure conformity with the Group’s accounting policies. The financial statements of all entities used for the purpose of consolidation are drawn up to same reporting date as that of the Company i.e., year ended on March 31. When the end of the reporting period of the parent is different from that of a subsidiary, the subsidiary prepares, for consolidation purposes, additional financial information as of the same date as the financial statements of the parent to enable the parent to consolidate the financial information of the subsidiary, unless it is impracticable to do so. Consolidation procedure - Combine like items of assets, liabilities, equity, income, expenses and cash flows of the parent on line by line basis with those of its subsidiaries. For this purpose, income and expenses of the subsidiary are based on the amounts of the assets and liabilities recognised in the Consolidated Financial Statements at the acquisition date. - Offset (eliminate) the carrying amount of the parent’s investment in each subsidiary and the parent’s portion of equity of each subsidiary. Business combinations policy explains how to account for any related goodwill. - Eliminate in full intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between entities of the Group (profits or losses resulting from intragroup transactions that are recognised in assets, such as inventory and property, plant and equipment, are eliminated in full). Intragroup losses may indicate an impairment that requires recognition in the Consolidated Financial Statements. IAS 12 - 'Income Taxes' applies to temporary differences that arise from the elimination of profits and losses resulting from intragroup transactions. 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, 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 into line with the Group’s accounting policies. 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. Changes in the Company’s interests in subsidiaries that do not result in a loss of control are accounted for as equity transactions. The carrying amount of the Group’s interests and the non-controlling interests are adjusted to reflect the changes in their relative interests in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognised directly in equity and attributed to the owners of the Company. If the Group loses control over a subsidiary, it: - Derecognises the assets (including goodwill) and liabilities of the subsidiary at their carrying amounts at the date when control is lost - Derecognises the carrying amount of any non-controlling interests - Derecognises the cumulative translation differences recorded in equity - Recognises the fair value of the consideration received and deferred consideration receivable - Recognises the fair value of any investment retained - Recognises any surplus or deficit in profit or loss - Recognise that distribution of shares of subsidiary to group in Group’s capacity as owners - Reclassifies the parent’s share of components previously recognised in OCI to profit or loss or retained earnings, as appropriate, as would be required if the group had directly disposed of the related assets or liabilities. Liability for put options with non-controlling interests Liability for put option issued to non-controlling interests, to be settled in cash by the Company, which do not grant present access to ownership interest to the Group is recognised at present value of the redemption amount and is reclassified from equity. At the end of each reporting period, the non-controlling interests subject to put option is derecognised and the difference between the amount derecognised and present value of the redemption amount, which is recorded as a financial liability, is accounted for as an equity transaction. If the put option is exercised, the amount recognised as financial liability at that date is extinguished by the payment of the exercise price.

Disclosure Of Summary of Significant Accounting Policies [Abstract]
Summary of significant accounting policies	4.1. Summary of significant accounting policies The following are the significant accounting policies applied by the Group in preparing its consolidated financial statements: a) 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. 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 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 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 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. b) Investment in associates and jointly controlled entities (joint ventures) An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but is not control or joint control over those policies. 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 significant influence or joint control are similar to those necessary to determine control over subsidiaries. The Group’s investment in its associate and joint venture are accounted for using the equity method. Under the equity method, the investment in an associate or 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 associate or joint venture since the acquisition date. Goodwill relating to the associate or 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 associate or 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 associate or 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 associate or joint venture are eliminated to the extent of the interest in the associate or joint venture. The aggregate of the Group’s share of profit or loss of an associate and a joint venture is shown on the face of the statement of profit or loss outside operating profit and represents profit or loss after tax and non-controlling interests in the subsidiaries of the associate or joint venture. The financial statements of the associate or 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 associate or 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 associate or joint venture and its carrying value, and then recognises the loss within ‘Share of profit of an associate and a joint venture’ in profit or loss. Upon loss of significant influence over the associate or 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 associate or joint venture upon loss of significant influence or joint control and the fair value of the retained investment and proceeds from disposal is recognised in profit or loss. Interests in joint operations 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. 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. 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. When a Group entity transacts with a joint operation in which a Group entity is a joint operator (such as a sale or contribution of assets), the Group is considered to be conducting the transaction with the other parties to the joint operation, and gains and losses resulting from the transactions are recognised in the Group’s consolidated financial statements only to the extent of other parties’ interests in the joint operation. When a Group entity transacts with a joint operation in which a Group entity is a joint operator (such as a purchase of assets), the Group does not recognise its share of the gains and losses until it resells those assets to a third party. c) Current versus non-current classification The Group presents assets and liabilities in the statement of financial position based on current / non-current classification. An asset is treated as current when it is: • Expected to be realised or intended to sold or consumed in normal operating cycle • Held primarily for the purpose of trading • Expected to be realised within twelve months after the reporting period, or • Cash or cash equivalents unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period All other assets are classified as non-current. A liability is treated as current when it is: • Expected to be settled in normal operating cycle • Held primarily for the purpose of trading • Due to be settled within twelve months after the reporting period, or • There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period All other liabilities are classified as non-current. Deferred tax assets / liabilities are classified as non-current assets / liabilities. The terms of the liability that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification. 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 twelve months as their operating cycle for classification of their current assets and liabilities. d) 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 fair value measurement of a non-financial asset takes into account a market participant’s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use. 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. 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. For the purpose of fair value disclosures, the Group has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy, as explained above. This note summarises the accounting policy for determination of fair value. Other fair value related disclosures are given in the relevant notes as following: • Disclosures for significant estimates and assumptions (refer Note 59) • Quantitative disclosures of fair value measurement hierarchy (refer Note 49) • Financial instruments (including those carried at amortised cost) (refer Note 48 and 49) e) 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. a) Sale of power Income from supply of power is recognised over time 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 and existence of a significant financing component. There is only one performance obligation in the arrangement and therefore, allocation of transaction price is not required. b) Income from services (management consultancy) The Group recognises revenue from projects management / technical consultancy over time because the customer simultaneously receives and consumes the benefits provided to them, as per the terms of the agreement entered with the customer. c) Sale of equipment Revenue from sale of equipment is recognised at the point in time when control of the asset is transferred to the customer, generally on delivery of the equipment. 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 equipment, the Group considers the effects of variable consideration, the existence of significant financing components, non-cash consideration, and consideration payable to the customer. There is only one performance obligation in the arrangement and therefore, allocation of transaction price is not required. d) Income from operation and maintenance services Revenue from operation and maintenance services are recognised over time as per the terms of agreement. e) 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. - Significant financing component Significant financing component for customer contracts is considered for the length of time between the customers’ payment and the transfer of the performance obligation, as well as the prevailing interest rate in the market. The transaction price for these contracts is discounted, using the interest rate implicit in the contract. This rate is commensurate with the rate that would be reflected in a separate financing transaction between the Group and the customer at contract inception. f) 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. Operation or service revenue is recognised in the period in which the services are provided by 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’s recognise 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 a) 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 before the customer pays consideration or before payment is due, a contract asset is recognised for the earned consideration that is conditional. Contract assets are subject to impairment assessment. Refer to accounting policies in section (o) Impairment of non-financial assets. b) 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). c) 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. (iii) Others Income from compensation for loss of revenue is recognised after certainty of receipt of the same is established. f) 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 RPPL and its subsidiaries, whose functional currency is INR. 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 translation 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 profit or loss with the exception of monetary items that are designated as part of the hedge of the Group’s net investment in a foreign operation. These are recognised in OCI until the net investment is disposed of, at which time, the cumulative amount is reclassified to profit or loss. Tax charges and credits attributable to exchange differences on those monetary items are also recognised in OCI. 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. The gain or loss arising on translation of non-monetary items measured at fair value is treated in line with the recognition of the gain or loss on the change in fair value of the item (i.e., translation differences on items whose fair value gain or loss is recognised in OCI or profit or loss are also recognised in OCI or profit or loss, respectively). 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. g) 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 in India. Current income tax relating to items recognised outside profit or loss is recognised outside 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, affects neither the accounting profit nor taxable profit or loss. - In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when 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, affects neither the accounting profit nor taxable profit or loss - in respect of deductible temporary differences associated with investments in subsidiaries, associates 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.

Below is the break-up for goodwill for each group of cash generating units and individual cash generating units (CGU): As at March 31, Group of CGU / individual CGU 2023 2022 Ostro Energy Group (wind power segment) 9,903 9,903 ReNew Vayu Urja (wind power segment) 756 756 Prathamesh Solarfarms (solar power segment) 428 428 Others (wind power segment)* 145 145 Others (solar power segment)* 364 364 * includes amount allocated against multiple CGUs and the amount allocated to each CGU is not material. The Group undertook the impairment testing of Goodwill assigned to each Individual or Group of CGUs as at March 31, 2023 and 2022 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 (for wind segment) and past performance (for solar segment); operation and maintenance expenses are based on prevaling prices and adjusted for inflation; and discount rates are based on weighed 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 2023 2022 Ostro Energy Group (wind power segment) 1 583 3,851 ReNew Vayu Urja (wind power segment) 2 1,831 419 Prathamesh Solarfarms (solar power segment) 3 964 2,054 Others (wind power segment) 2 1,706 1,925 Others (solar power segment) 3 1,844 2,328 (1) Increase in discount rate by 0.11 % per annum or decrease in PLF by 0.18 % or increase in future operating and maintenance expenses by 8 % per annum, would result in value in use to be equal to the carrying amount. 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 11.32 % (March 31, 2022: 11.20 %), PLF of 26.27 % (March 31, 2022: 27.76 %) and future operating and maintenance costs of INR 0.75 million per MW (March 31, 2022: INR 0.70 million per MW) adjusted for future inflation. (2) 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. The Group has currently estimated discount rates ranging between 10.55 % to 12.38 % (March 31, 2022: 11.05 % to 12.34 %), PLF of 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, 2022: INR 0.70 million per MW) adjusted for future inflation. (3) 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. The Group has currently estimated discount rates ranging between 10.68 % - 11.51 % (March 31, 2022: 10.29 % to 10.97 %), PLF of 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, 2022: INR 0.47 million per MW) adjusted for future inflation.

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 in 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 9,052 (March 31, 2022: INR 4,018 ) having an expiry period of 1 to 8 years (March 31, 2022: 4 to 8 years), capital losses amounting to INR 828 (March 31, 2022: INR 828 ) having an expiry period of 6 years, unabsorbed depreciation amounting to INR 5,917 (March 31, 2022: INR 8,040 ) which are available for utilisation indefinitely and MAT credit amounting to INR 213 (March 31, 2022: INR 316 ) having an expiry period of 6 - 15 years (March 31, 2022: 8 - 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. 11E. There are additional disallowances / additions to returned income of RPPL 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, 2022: INR 1,106 ) 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.

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 as its broker (the Broker) for the Share Repurchase Program.

All the foregoing shares (including the 1,655,300 which were held pending for cancellation as of March 31, 2022) have been repurchased into treasury by the Company, so that the total number of shares repurchased into treasury during the year was 28,010,273 . Consequently, the retained earnings account has been reduced by INR 13,499 (March 31, 2022: INR 997 ). Terms / rights attached to equity shares of RPPL RPPL 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 RPPL. Post this transaction, the number and type of equity instruments issued, reflects the equity structure of the Company.

The Group regularly assesses these assumptions with the projected long-term plans and prevalent industry standards. The impact of sensitivity due to changes in the significant actuarial assumptions on the defined benefit obligations is given in the table below: Change in Impact on provision for gratuity as at March 31, Particulars assumptions 2022 2023 2023 (INR) (INR) (USD) Discount rate + 0.5 % 184 223 3 - 0.5 % 197 240 3 Salary escalation + 0.5 % 195 238 3 - 0.5 % 185 225 3 The sensitivity analysis above has been determined based on a method that extrapolates the impact on defined benefit obligation as a result of reasonable changes in key assumptions occurring at the end of the year. d) Projected plan cash flow The table below shows the expected cash flow profile of the benefits to be paid to the current membership of the plan based on past service of the employees as at the valuation date: Maturity profile As at March 31, 2022 2023 2023 (INR) (INR) (USD) Within next 12 months 20 24 0 From 2 nd to 5 th year 90 100 1 From 6 th to 9 th year 76 94 1 From 10 th year and beyond 147 241 3 The weighted average duration to the payment of these cash flows is 7.92 years (March 31, 2022: 7.15 years and March 31, 2021: 13 years). e) Risk analysis The Group is exposed to a number of risks in the defined benefit plans. Most significant risks pertaining to defined benefits plans and management estimation of the impact of these risks are as follows: i) Inflation risk: Currently the Group has not funded the defined benefit plans. Therefore, the Group will have to bear the entire increase in liability on account of inflation. ii) Longevity risk / life expectancy: The present value of the defined benefit plan liability is calculated by reference to the best estimate of the mortality of plan participants both during and at the end of the employment. An increase in the life expectancy of the plan participants will increase the plan liability. iii) Salary growth risk: The present value of the defined benefit plan liability is calculated by reference to the future salaries of plan participants. An increase in the salary of the plan participants will increase the plan liability.

Surrendered options are subject to value adjustment in case Group or any of its holding company issues primary securities or on signing of any definitive agreements before July 31, 2021 at higher / lower than INR 420 per share (adjusted for capital restructurings, consolidations, split etc.). Actual adjustments for upside or downside were to be settled post completion of the deal. As per the terms, upsides were to be accrued to an employee only if they continue in employment as of 31 July 2021 and employee was liable for downside value adjustment even if he or she ceased employment. The terms also stated that if no deal is completed by October 31, 2021, the deal will be disregarded for adjustments. During the year ended March 31, 2022, the Group paid INR 524 on account of upside accrued to the employees. The details of repurchase of vested stock options are as follows: Particulars Amount Total consideration paid for repurchase of vested stock options (a) 681 Fair value of the vested stock options repurchased, measured at the repurchase date, recognised in equity (b)* 650 Excess consideration paid recognised in statement of profit or loss (a) - (b) 31 * The fair value of vested stock options was estimated at the date of repurchase using Black-Scholes valuation model, taking into account the terms and conditions upon which the share options were granted using following inputs as at July 31, 2020. Particulars March 31, 2021 Share price per share at measurement date 420 Expected volatility 22 % Dividend yield 3.40 % Risk-free interest rate 4.16 % - 5.92 % 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. Transaction during the year ended March 31, 2022 RPPL during year ended March 31, 2022 repurchased 264,480 vested options of two of its employees who passed away due to COVID-19 and has paid INR 89 at fair value of options on the date of repurchase. c) Cash settled share based payments arising out of a one-time partial liquidity scheme (refer note (b) above) The carrying amount of the liability (included in employee benefit liabilities) relating to the cash settled share based payments at March 31, 2023 was INR Nil (March 31, 2022: INR Nil ; March 31, 2021: INR 102 ). RPPL had settled all of the outstanding the cash settled options on August 23, 2021 by paying cash of INR 201.75 per option, as per terms of these options, which resulted in total outflow of INR 524 during the year ended March 31, 2022. The fair value of the cash settled share based payments was determined using the Black-Scholes model using the following inputs as at March 31, 2021: Particulars March 31, 2021 Share price per share at measurement date 420 Expected volatility 22 % Dividend yield 3.40 % Risk-free interest rate 4.16 % - 5.92 % 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. d) Replacement of Group Stock Option Plans On August 23, 2021, all vested and unvested option outstanding for Group Stock Option Plans were replaced by the ‘2021 Stock Entitlement Program’ of the Company (Holding Company Stock Option Plans). 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. The fair value of stock options was estimated at the date of replacement using Black-Scholes valuation model, taking into account the terms and conditions upon which the share options were granted. Following are the assumptions used in valuation of Holding Company Stock Option Plan as on the date of replacement: Particulars Group Stock Holding Company 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.

As part of the transaction, the Company has issued warrants to these warrants’ holders (refer below for terms of these warrants), which will entitle these warrants holders to purchase Company’s Class A equity shares. These warrants are classified to be derivative instruments and as such, are recorded at fair value through profit or loss account. The Company will continue to adjust the fair value of the warrant liability at the end of each reporting period for changes in fair value from the prior period until the earlier of the exercise or expiration of the applicable warrants or until such time that the warrants are no longer determined to be derivative instruments.

In the event of default, the Group will have to repay the non-convertible debentures. The Group has not received any consideration for guarantee given. The Group had initially measured financial guarantee at fair value amounting INR 121 with corresponding amount recognised in equity as distributions to equity shareholder. The said guarantee was revoked in August 2021. According to Group’s policy, amortisation is calculated on straight-line basis until maturity of the contract. During the year ended March 31, 2023, an amortisation of INR Nil (March 31, 2022: 78 ; March 31, 2021: INR 43 ) has been recognised under head "other income" in the statement of profit or loss. The carrying amounts of the related financial guarantee contracts recognised in the consolidated financial statements is INR Nil (March 31, 2022: Nil; March 31, 2021: INR 78 ). The amount of loss allowance as at March 31, 2021 was lower than the fair value of financial guarantee initially recognised less cumulative amortisation, therefore no loss allowance was recognised in profit or loss for the financial guarantee contract. b) Put option with non controlling interest During the year ended March 31, 2022, the Company had granted an option to the CEO, to purchase his entire shareholding in RPPL, which was held directly or indirectly by him.

For all other instruments, following methods and assumptions were used to estimate the fair values: i) Fair values of the Group’s term loans from banks, term loans from financial institutions, non-convertible debentures, acceptances and senior secured notes 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 own credit risk. The own non-performance risk as at March 31, 2023 and 2022 was assessed to be insignificant. ii) Fair values of the liability component of compulsory convertible preference shares and compulsory convertible debentures 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, 2023 and 2022 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.

Fair Value Measurement Hierarch

Disclosure of fair value measurement hierarchy [abstract]
Fair Value Measurement Hierarchy	49. Fair value measurement hierarchy The Group categorises assets and liabilities measured at fair value into one of three levels depending on the ability to observe inputs employed in their measurement which are described as follows: • 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 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. There were no changes in the Group’s valuation processes, valuation techniques, and types of inputs used in the fair value measurements during the year.

Financial Risk Management Objectives And Policies [Abstract]
Financial risk management objectives and policies	50. 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, 2023 and 2022. 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, 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, 2021 2022 2023 Increase / decrease in basis points Effect on profit before tax Increase / decrease in basis points Effect on profit before tax Increase / decrease in basis points Effect on profit before tax INR + / (-) 50 (-) / + 646 + / (-) 50 (-) / + 361 + / (-) 50 (-) / + 727 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, 2023 and 2022 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 46 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 trade receivable balances of the Group are evenly spread over customers. 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, 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 As at March 31, 2022 Trade receivables (days past due) 0 - 6 months* 6 -12 months 12 -18 months > 18 months Total Gross carrying amount 17,831 14,060 3,277 11,623 46,791 Expected credit loss 233 304 103 326 966 * 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 within credit limits assigned to each counterparty. Counterparty credit limits are reviewed on an annual basis by the Group, and may be updated throughout the year subject to approval of group's finance committee. 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 44), 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 64 (March 31, 2022: INR 122 ) increase / (decrease) on the profit or loss for the year ended March 31, 2023 of the Group . Put options Non-controlling shareholders of RPPL 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 270 increase / (decrease) on the total equity of the Group for the year ended March 31, 2023 (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: As at March 31, 2023 On demand Less than 3 to 12 1 to 5 years > 5 years Total Borrowings Non convertible debentures (secured)* — — — 83,396 7,012 90,408 Compulsorily convertible debentures* — — — 11,416 40,263 51,679 Term loan from banks* — — — 97,633 47,709 145,342 Loans from financial institutions* — — — 122,648 146,258 268,906 Senior secured notes* — — — 77,371 48,989 126,360 Short term interest-bearing loans and borrowings Acceptances (secured) — 15,792 8,634 — — 24,426 Term loan from banks and financial institutions (secured) — 2,500 2,056 — — 4,556 Working capital term loan (secured) — 8,490 5,051 — — 13,541 Other financial liabilities Lease liabilities — 166 522 2,195 14,554 17,437 Current maturities of long term interest-bearing loans and borrowings* — 10,036 44,655 — — 54,691 Interest accrued but not due on borrowings — 1,194 823 — — 2,017 Interest accrued but not due on debentures — 981 214 — — 1,195 Capital creditors — 33,480 — — — 33,480 Purchase consideration payable — 1,681 — — — 1,681 Trade payables Trade payables — 6,118 — — — 6,118 As at March 31, 2022 On demand Less than 3 to 12 1 to 5 years > 5 years Total Borrowings Non convertible debentures (secured)* — — — 90,763 5,402 96,165 Compulsorily convertible debentures* — — — 346 616 962 Term loan from banks* — — — 47,780 38,733 86,513 Loans from financial institutions* — — — 60,623 109,100 169,723 Senior secured notes* — — — 81,356 84,636 165,993 Short term interest-bearing loans and borrowings Acceptances (secured) — 3,686 919 — — 4,605 Buyer's / supplier's credit (secured) — — 5,400 — — 5,400 Working capital term loan (secured) — 2,750 1,730 — — 4,480 Other financial liabilities Lease liabilities — 148 338 1,334 9,370 11,190 Current maturities of long term interest-bearing loans and borrowings* 653 8,930 76,132 — — 85,715 Interest accrued but not due on borrowings — 384 1,437 — — 1,821 Interest accrued but not due on debentures — 1,233 804 — — 2,037 Capital creditors — 11,036 — — — 11,036 Purchase consideration payable — 88 — — — 88 Trade payables Trade payables — 5,613 — — — 5,613 * Including future interest payments.

Capital Management [Abstract]
Capital management	51. Capital management For the purpose of the capital management, capital includes issued equity capital, compulsorily convertible debentures, compulsorily convertible preference shares, Securities 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. 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. For all long-term loan arrangements from banks, the Group has complied with the debt covenants as at March 31, 2023. For the year ended March 31, 2022, the Group could not meet covenants for a long-term loan arrangement amounting to INR 653 wherein the liability became payable on demand. The Group has classified these liabilities as current as on March 31, 2022. No changes were made in the objectives, policies or processes for managing capital during the years ended March 31, 2023, 2022 and 2021.

Legal Matters [Abstract]
Legal matters	53. Legal matters (a) Dispute with Southern Power Distribution Company of Andhra Pradesh Limited Certain subsidiaries 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: a. 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. As at March 31, 2023 and March 31, 2022, the cumulative amount recoverable from the APDISCOM pertaining to period from February 2017 till July 2018, included in trade receivables amounts to INR 1,004 (March 31, 2022: INR 1,004 million). The AP entities have filed an interim application in AP High Court seeking payment of amount wrongfully deducted by the APDISCOM. The management basis legal opinion obtained by it 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. b. 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 entered into in 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 enumerating the following: i. Writ petition is allowed, and both GO and the subsequent letters are set aside. ii. Further, APDISCOM were instructed to honour 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, certain power generating companies other than ReNew Group filed petitions under Article 139 of the Constitution of India before the Supreme Court seeking transfer of the proceedings pending before the Division Bench of the High Court, and for adjudication of the same by the Supreme Court. APDISCOM has also filed a Special Leave Petition (SLP) in the Supreme Court in October 2020 against the Judgment and order dated December 19, 2019 in I.A. No. 9 of 2019 in W.P. No. 9876 of 2019 of another power generating company in the industry, which modified the Order dated September 24, 2019, passed by Single Judge of AP High Court and directed APDISCOM to make payments at the rate mentioned in PPAs. The AP Entities through its Holding Company, ReNew Power Private Limited, has filed an impleadment application in the SLP apprehending that any order or observation of the Supreme Court may have an adverse impact on the Order dated September 24, 2019 and W.A. No. 6 of 2020 and batch pending before Division Bench of the AP High Court. APDISCOM was directed in order dated October 1, 2021 by the AP High Court to pay 50 % amount of the outstanding invoices raised till June 30, 2021. APDISCOM did not comply with this order. Thereafter, the next appeal was heard on November 8, 2021 where APDISCOM was given three more weeks to make the said payment. In subsequent hearing held on December 8, 2021, the AP High Court noted that payments have been made upto May 2021 and APDISCOM had sought some more time for payment of the remaining amounts at the interim rate. The AP High Court had directed APDISCOM to make the payments for June 2021 by December 29, 2021 and was asked to file an affidavit with payment schedule for payments for the third and fourth quarter of 2021. The payments so directed by the AP High Court were received in December 2021. Thereafter, by its common final order dated March 15, 2022, the AP High Court 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. Thereafter, APDISCOM has filed an application before the AP High Court seeking extension of the period of 6 weeks’ time granted by the High Court for payment of all outstanding amounts. Certain power generation companies have also filed applications before the High Court seeking implementation of the final order dated March 15, 2022. Subsequently, APDISCOM have undertaken to pay the outstanding receivable amounting to INR 15,354 in 12 monthly instalments as per the mechanism provided for under the Electricity (Late Payment Surcharge and related matters) Rules, 2022 issued by the Ministry of Power, Government of India (refer Note 38). Pursuant thereto, APDISCOM have paid 8 out of the 12 instalments, as on March 31, 2023 of all undisputed amounts.. APDISCOM have also 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. Further, the Supreme Court by its common Order dated January 2, 2023, has dismissed two petitions filed against the direction to release all payments. Thereafter, as stated herein above, final hearing had commenced in the matter in the months of May, 2023. The next date of hearing in the matter is awaited. AP entities have total outstanding receivables of INR 11,903 as at March 31, 2023 (March 31, 2022: INR 17,411 ) from sale of electricity against such PPAs [including an amount of INR 1,004 for GBI receivable as explained in part (a) to the note], which was the subject matter of dispute. Subsequent to March 31, 2023, AP entities have received a sum of INR 4,202 from APDISCOM. In view of the favourable order by the AP High Court and basis legal opinions obtained by the Company, management believes that it has strong merits in the case and no additional adjustment is required in the consolidated financial statements. (b) Dispute with Karnataka Electricity Regulatory Commission Distribution companies of the state of Karnataka issued demand notices to captive users (customers of certain Group’s subsidiaries) and to the respective captive plants (hereinafter refer to as the "SPVs"), alleging that captive users had not consumed energy in proportion to their respective shareholding in the SPVs, thereby failing to maintain their Captive Status in accordance with Rule 3 of the Electricity Rules, 2005, and consequently, were liable to pay cross subsidy surcharge and differential between rate of electricity tax applicable on the energy consumed in the entire year. SPVs had deposited a sum of INR 114 (March 31, 2022: INR 114 ) under protest against the demand raised by distribution companies amounting INR 298 (March 31, 2022: INR 298 ) in relation to the demand notices up to financial year ended March 31, 2018. Thereafter, the SPVs had filed petitions before the Karnataka Electricity Regulatory Commission (KERC) contesting these demands. On July 20, 2022, KERC has reserved the petitions for final orders which are awaited. KERC had granted interim relief and stayed the demand notice and disconnection by the distribution companies till final adjudication of the petitions. The amount paid under protest has been accounted for as recoverable and disclosed under head “Other current assets” in these financial statements. Apart from above, a sum of INR 216 has been demanded by distribution companies from some of the captive users of the SPVs towards energy supplied till March 31, 2023, alleging that the captive user had not consumed energy in proportion to its respective shareholding in the SPVs. The SPVs have filed a writ petitions in July 2019 and August 2020 before the High Court of Karnataka challenging such demands and seeking their quashing. The High Court, vide Orders dated July 18, 2019, December 18, 2019, September 18, 2020 and October 6, 2020, has directed that no precipitative action shall be taken on these demand notices till final adjudication of the petitions. By its final order dated March 7, 2023, KERC has allowed the petition in favour of ReNew Wind Energy (Karnataka) Private Limited and quashed the demand letters. However, the final order in the petition for ReNew Wind Energy (AP) Private Limited is awaited. The petitions before the High court are pending. Based on legal advice obtained, believes that there are merits in its position and that the demand raised by distribution companies would be rescinded by relevant legal authorities and hence no adjustment has been made in the consolidated financial statements in this regard. (c) Order of the Supreme Court of India to underground high-tension power lines In 2019, a petition in public interest (the “Writ Petition”) was filed before the Supreme Court of India to seek directions to save two protected species of birds in the state of Rajasthan and Gujarat (the ‘Birds’) stating that these Birds collide with overhead transmission lines and suffer injuries or die. During the current period, on April 19, 2021, the Supreme Court has ordered (the “Order”) for all existing and future power lines to be undergrounded, subject to feasibility in case of high-tension power lines. As at March 31, 2023, operational capacity in the Rajasthan and Gujarat projects likely to be affected by the Supreme Court order was 1,813.8 MW and the capacity of the under-development projects in Rajasthan and Gujarat, which are likely to be impacted by the Supreme Court order was 2,585 MW. The Group along with other companies in the industry affected by the Order have filed applications seeking certain modification of the directions passed by the Supreme Court of India, including (i) exemption from undergrounding for existing power projects and (ii) declaration of the cost of undergrounding as a pass-through under the various power purchase agreements. Applications have also been filed by the Ministry of New and Renewable Energy and the Government of Rajasthan, seeking similar modifications. Through Order dated April 21, 2022, the Supreme Court of India directed (i) completion of installation of bird diverters on all overhead transmission lines in the Priority Area identified by the Supreme Court by July 20, 2022 and (ii) all affected projects to approach the Technical Expert Committee appointed by it to seek any exemption from undergrounding and to approach the Supreme Court thereafter in case of any grievance from the decision of the committee. Thereafter the matter was heard on November 30, 2022, on which date the Supreme Court directed (i) The Chief Secretaries of the States of Rajasthan and Gujarat shall ensure that within the priority areas, a comprehensive exercise is completed no later than within a period of six weeks to assess (a) the total length of transmission lines; and (b) the estimated number of bird divertors required for the purpose, and filed affidavits indicating the outcome of the exercise and the number of bird diverters required to be installed, (ii) the Expert Committee appointed by the Supreme Court to file an updated report before the next date of hearing on the status of applications which have been submitted to it and those that have been cleared in the meantime, and (iii) to file an updated status report within 6 weeks on the steps which have been taken to complete the tendering process and install bird diverters. The Group has completed installation of bird diverters on its dedicated transmission lines in the priority area as per the directions contained in the Orders dated April 21, 2022 and November 30, 2022. The Company has also received exemptions from undergrounding some of its transmission lines from the Technical Committee appointed by the Supreme Court, and is in the process for applying for exemptions for other affected lines. Management expects that the Supreme Court is likely to hear and conclude the captioned matter expeditiously in July 2023.The next date in the matter is awaited. In the interim, in parallel the Company is approaching the Expert Committee for exemption from undergrounding in a phased manner, after conducting route surveys and other studies to support the case for exemption. Further, management, basis legal opinion obtained by it believes that the additional cost that will be incurred by the Group shall be recovered from customers under respective PPAs through provisions relating to change in law and force majeure and hence no material financial implication is likely to devolve on the Group.

Acquisition of ReGen Powertech Private Limited	58. 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 of INR 716 out of the total consideration of INR 1,675 , to the Committee of Creditors (CoC). Further, as per the resolution plan, ReNew Power Services paid the first tranche on March 2, 2022 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's 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, which deferment has been continued by subsequent orders. 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. ReNew Power Services has applied to NCLAT to have the order deferring implementation of the resolution plan vacated, which is pending adjudication. The NCLAT has commenced final hearing of aforementioned appeals, the matter was last listed on June 30, 2023 but the matter could not be taken up due to unavailability of the bench. Next date of hearing in the matter is awaited. 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.

Disclosure Of Accounting Judgements And Estimates [Abstract]
Significant accounting judgments, estimates and assumptions	59. 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 The key assumptions used to determine the recoverable amount for the different CGUs or 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. There were no significant accounting judgements.

Transmission line projects accounted for under IFRIC 12, 'Service Concession Arrangements'	60. Transmission line projects accounted for under IFRIC 12, 'Service Concession Arrangements' During the year ended March 31, 2023, the Group through its subsidiaries engaged in transmission business wherein the subsidiaries have entered into Transmission Services Agreements (TSA) with the Government (Grantor) on Build, Own, Operate and Maintain (BOOM) or Build, Own, Operate and Transfer (BOOT) basis. The Group through its subsidiaries acts as a transmission licensee. 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 maintaining these Transmission projects for the entire concession period which is approximately equal to the useful life of the transmission assets. All Transmission projects have fixed annual levelised tariff as per terms of TSA. These arrangements fall under the purview IFRIC 12, 'Service Concession Arrangements' and have been accounted as per financial asset model. As at March 31, 2023, all the transmission projects are under the construction phase. The transaction price allocated to the remaining construction activites and operation and maintenance services is approximately 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. The Group expects to complete the constuction activities within next two years. Further, operating and maintenance services shall be completed over the tenure of TSAs. The movement of contract assets are summarised below: As at March 31, 2023 2023 (INR) (USD) Balance at the beginning of the year — — Recognition of contract assets pursuant to recognition of construction revenue* 7,557 92 Unwinding of contract assets (calculated at the rate of 7.62 % p.a. to 7.91 % p.a.) 154 2 Balance at the end of the year 7,711 94 Non-current 7,139 87 Current 572 7 * includes profit of INR 292 .

Disclosure Of Summary of Significant Accounting Policies [Abstract]
Business combinations and goodwill	a) 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. 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 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 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 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 associates and jointly controlled entities (joint ventures)	b) Investment in associates and jointly controlled entities (joint ventures) An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but is not control or joint control over those policies. 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 significant influence or joint control are similar to those necessary to determine control over subsidiaries. The Group’s investment in its associate and joint venture are accounted for using the equity method. Under the equity method, the investment in an associate or 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 associate or joint venture since the acquisition date. Goodwill relating to the associate or 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 associate or 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 associate or 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 associate or joint venture are eliminated to the extent of the interest in the associate or joint venture. The aggregate of the Group’s share of profit or loss of an associate and a joint venture is shown on the face of the statement of profit or loss outside operating profit and represents profit or loss after tax and non-controlling interests in the subsidiaries of the associate or joint venture. The financial statements of the associate or 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 associate or 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 associate or joint venture and its carrying value, and then recognises the loss within ‘Share of profit of an associate and a joint venture’ in profit or loss. Upon loss of significant influence over the associate or 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 associate or joint venture upon loss of significant influence or joint control and the fair value of the retained investment and proceeds from disposal is recognised in profit or loss. Interests in joint operations 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. 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. 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. When a Group entity transacts with a joint operation in which a Group entity is a joint operator (such as a sale or contribution of assets), the Group is considered to be conducting the transaction with the other parties to the joint operation, and gains and losses resulting from the transactions are recognised in the Group’s consolidated financial statements only to the extent of other parties’ interests in the joint operation. When a Group entity transacts with a joint operation in which a Group entity is a joint operator (such as a purchase of assets), the Group does not recognise its share of the gains and losses until it resells those assets to a third party.
Current versus non-current classification	c) Current versus non-current classification The Group presents assets and liabilities in the statement of financial position based on current / non-current classification. An asset is treated as current when it is: • Expected to be realised or intended to sold or consumed in normal operating cycle • Held primarily for the purpose of trading • Expected to be realised within twelve months after the reporting period, or • Cash or cash equivalents unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period All other assets are classified as non-current. A liability is treated as current when it is: • Expected to be settled in normal operating cycle • Held primarily for the purpose of trading • Due to be settled within twelve months after the reporting period, or • There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period All other liabilities are classified as non-current. Deferred tax assets / liabilities are classified as non-current assets / liabilities. The terms of the liability that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification. 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 twelve months as their operating cycle for classification of their current assets and liabilities.
Fair value measurement	d) 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 fair value measurement of a non-financial asset takes into account a market participant’s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use. 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. 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. For the purpose of fair value disclosures, the Group has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy, as explained above. This note summarises the accounting policy for determination of fair value. Other fair value related disclosures are given in the relevant notes as following: • Disclosures for significant estimates and assumptions (refer Note 59) • Quantitative disclosures of fair value measurement hierarchy (refer Note 49) • Financial instruments (including those carried at amortised cost) (refer Note 48 and 49)
Revenue recognition	e) 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. a) Sale of power Income from supply of power is recognised over time 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 and existence of a significant financing component. There is only one performance obligation in the arrangement and therefore, allocation of transaction price is not required. b) Income from services (management consultancy) The Group recognises revenue from projects management / technical consultancy over time because the customer simultaneously receives and consumes the benefits provided to them, as per the terms of the agreement entered with the customer. c) Sale of equipment Revenue from sale of equipment is recognised at the point in time when control of the asset is transferred to the customer, generally on delivery of the equipment. 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 equipment, the Group considers the effects of variable consideration, the existence of significant financing components, non-cash consideration, and consideration payable to the customer. There is only one performance obligation in the arrangement and therefore, allocation of transaction price is not required. d) Income from operation and maintenance services Revenue from operation and maintenance services are recognised over time as per the terms of agreement. e) 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. - Significant financing component Significant financing component for customer contracts is considered for the length of time between the customers’ payment and the transfer of the performance obligation, as well as the prevailing interest rate in the market. The transaction price for these contracts is discounted, using the interest rate implicit in the contract. This rate is commensurate with the rate that would be reflected in a separate financing transaction between the Group and the customer at contract inception. f) 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. Operation or service revenue is recognised in the period in which the services are provided by 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’s recognise 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 a) 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 before the customer pays consideration or before payment is due, a contract asset is recognised for the earned consideration that is conditional. Contract assets are subject to impairment assessment. Refer to accounting policies in section (o) Impairment of non-financial assets. b) 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). c) 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. (iii) Others Income from compensation for loss of revenue is recognised after certainty of receipt of the same is established.
Foreign currencies	f) 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 RPPL and its subsidiaries, whose functional currency is INR. 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 translation 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 profit or loss with the exception of monetary items that are designated as part of the hedge of the Group’s net investment in a foreign operation. These are recognised in OCI until the net investment is disposed of, at which time, the cumulative amount is reclassified to profit or loss. Tax charges and credits attributable to exchange differences on those monetary items are also recognised in OCI. 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. The gain or loss arising on translation of non-monetary items measured at fair value is treated in line with the recognition of the gain or loss on the change in fair value of the item (i.e., translation differences on items whose fair value gain or loss is recognised in OCI or profit or loss are also recognised in OCI or profit or loss, respectively). 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	g) 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 in India. Current income tax relating to items recognised outside profit or loss is recognised outside 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, affects neither the accounting profit nor taxable profit or loss. - In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when 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, affects neither the accounting profit nor taxable profit or loss - in respect of deductible temporary differences associated with investments in subsidiaries, associates 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 restrict the recognition of deferred tax assets to the extent that it has become reasonably certain 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 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	h) Government grants Government grants are 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 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. When the Group receive grants of non-monetary assets, the asset and the grant are recorded at fair value amounts and released to profit or loss over the expected useful life in a pattern of consumption of the benefit of the underlying asset i.e. by equal annual instalments. The Group presents grants related to an expense item as other income in the statement of profit or loss. Thus, generation based incentive and Sale of emission reduction certificates have been recognised as other income. Generation based incentive Generation based incentive is recognised on the basis of supply of units generated by the Group to the state electricity board from the eligible project in accordance with the scheme of the "Generation Based Incentive (GBI) for Grid Interactive Wind Power Projects". Subsidy (Viability Gap Funding) The Group receives Viability Gap Funding (VGF) for setting up of certain solar power projects. The Group records the VGF proceeds on fulfilment of the underlying conditions as deferred government grant. Such deferred grant is recognised over the period of useful life of underlying asset. Sale of emission reduction certificates Government grants in the form of carbon emission rights (CERs), which are received on projects registered under the United Nations Framework on Climate Change, are recorded as inventory and initially measured at fair value when there is reasonable assurance that such CERs will be received, with credit being recognised as Income from sale of emission reduction certificates under other operating income in the statement of profit or loss. Such CERs are subsequently measured at cost or net realisable value, whichever is lower. The Group derecognises the CERs when the certificate is sold, which occurs when units are transferred to the customer.
Property, plant and equipment	i) 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. Refer to significant accounting judgements, estimates and assumptions and provisions (refer Note 25) for further information about the recognised decommissioning provision. 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 fixed assets 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	j) 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. Intangible assets with indefinite useful lives are not amortised, but are tested for impairment annually, either individually or at the cash-generating unit level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be supportable. If not, the change in useful life from indefinite to finite is made on a prospective basis. Development costs Development expenditure on an individual project are recognised as an intangible asset when the Group can demonstrate: • The technical feasibility of completing the intangible asset so that the asset will be available for use or sale • Its intention to complete and its ability and intention to use or sell the asset • How the asset will generate future economic benefits • The availability of resources to complete the asset • The ability to measure reliably the expenditure during development Following initial recognition of the development expenditure as an asset, the asset is carried at cost less any accumulated amortisation and accumulated impairment losses. Amortisation of the asset begins when development is complete and the asset is available for use. It is amortised over the period of expected future benefit.
Depreciation / amortisation of property, plant and equipment and intangible assets	k) 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 (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 Buildings (other than Temporary structure) 30 * Based on an external technical assessment, the management believes that the useful lives as given above and residual value of 0 %- 5 %, best represents the period over which management expects to use its assets and its residual value. 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	l) 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 of completion and the estimated costs necessary to make the sale.
Borrowing costs	m) Borrowing costs Borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalised during the period. 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. The EIR amortisation is recognised under finance costs in the statement of profit or loss. The amount amortised for the period from disbursement of borrowed funds upto the date of capitalisation of the qualifying assets is added to cost of the qualifying assets. 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. The Group treats as part of general borrowings any borrowing originally made to develop a qualifying asset when substantially all of the activities necessary to prepare that asset for its intended use or sale are complete.
Leases	n) 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. i) 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.
Impairment of non-financial assets	o) Impairment of non-financial assets The Group assess, 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 estimate the asset’s recoverable amount. An asset’s 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. These calculations are corroborated by valuation multiples, quoted share prices for publicly traded companies or other available fair value indicators. 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 a remaining life of the power purchase agreements of the project considering the long term fixed rate firm agreements available. Impairment losses of continuing operations, including impairment on inventories, are recognised in the statement of profit or loss. For assets excluding goodwill, an assessment is made at each reporting date to determine whether there is an indication that previously recognised impairment losses no longer exist or have decreased. If such indication exists, the Group estimates the asset's or CGU's recoverable amount. A previously recognised impairment loss is reversed only if there has been a change in the assumptions used to determine the asset's recoverable amount since the last impairment loss was recognised. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognised for the asset in prior years. Such reversal is recognised in the statement of profit or loss unless the asset is carried at a revalued amount, in which case, reversal is treated as an increase in revaluation. Goodwill is tested for impairment annually on March 31, or more frequently when there is an indication that the carrying value may be impaired. Impairment is determined for goodwill by assessing the recoverable value of each of the CGUs (or group of CGUs) to which the goodwill relates. When the recoverable value of CGU is less than its carrying value, an impairment loss is recognised. Impairment loss on Goodwill is never reversed in future.
Share based payments	p) 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-market 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, 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. On repurchase of vested equity instruments by the Group, the payment made to the employee shall be accounted for as a deduction from equity, except to the extent that the payment exceeds the fair value of the equity instruments repurchased, measured at the repurchase date. Any such excess shall be recognised as an expense in the statement of profit or loss. Cash-settled transactions A liability is recognised for the fair value of cash-settled transactions. The fair value is measured initially and at each reporting date up to and including the settlement date, with changes in fair value recognised in employee benefits expense (refer Note 35). The fair value is expensed over the period until the vesting date with recognition of a corresponding liability. The fair value is determined using a Black-Scholes model, further details of which are given in Note 43. The approach used to account for vesting conditions when measuring equity-settled transactions also applies to cash-settled transactions.
Retirement and other employee benefits	q) 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 recognise 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. Past service costs are recognised in statement of profit or loss on the earlier of: - The date of the plan amendment or curtailment; and - The date that the Group recognises related restructuring costs 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, past-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 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	r) 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	s) 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) Revenue from contracts with customers. Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the market place (regular way trades) are recognised on the trade date, i.e., the date that the Group commits to purchase or sell the asset. 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: a) The asset is held within a business model whose objective is to hold assets for collecting contractual cash flows; and b) 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 FVTOCI A ‘debt instrument’ is classified as at the FVTOCI if both of the following criteria are met: a) The objective of the business model is achieved both by collecting contractual cash flows and selling the financial assets; and b) The asset’s contractual cash flows represent solely payments of principal and interest. Debt instruments included within FVTOCI category are measured initially as well as at each reporting date at fair value. Fair value movements are recognised in OCI. However, the Group recognises interest income, impairment losses and reversals and foreign exchange gain or loss in the statement of profit or loss. On derecognition of the asset, cumulative gain or loss previously recognised in OCI is reclassified from the equity to statement of profit or loss. Interest earned whilst holding FVTOCI debt instrument is reported as interest income using the EIR method. 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. 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 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, or - The respective Group has transferred their rights to receive cash flows from the asset or have assumed the obligation to pay the received cash flows in full without material delay to a third party under a ‘pass-through’ arrangement; and - Either the Group has transferred substantially all the risks and rewards of the asset, or has neither transferred nor retained substantially all the risks and rewards of the asset, but have transferred control of the asset. When the Group has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Group continues to recognise the transferred asset to the extent of the continuing involvement of Group. In that case, the Group also recognises an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained. Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Group could be required to repay. 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 assessment of the correlation between historical observed default rates, forecast economic conditions and ECLs is a significant estimate. The amount of ECLs is sensitive to changes in circumstances and of forecast economic conditions. The Group’s historical credit loss experience and forecast of economic conditions may also not be representative of customer’s actual default in the future. 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 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. Compulsorily convertible preference shares Compulsorily Convertible Preference Shares (CCPS) are separated into liability and equity components based on the terms of the contract. On issuance of the CCPS, the fair value of the liability component is determined using a market rate for an equivalent non-convertible instrument. This amount is classified as a financial liability measured at amortised cost (net of transaction costs) until it is extinguished on conversion or redemption. The remainder of the proceeds is allocated to the conversion option that is recognised and included in equity since conversion option meets IAS 32 criteria for fixed to fixed classification. Transaction costs are deducted from equity and liability on pro-rata basis, net of associated income tax. The carrying amount of the conversion option is not remeasured in subsequent years. Transaction costs are apportioned between the liability and equity components of the CCPS based on the allocation of proceeds to the liability and equity components when the instruments are initially recognised. Compound instruments - Compulsorily Convertible Debentures Compulsorily Convertible Debentures (CCDs) 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 CCDs. 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. Reclassification of financial assets and liabilities The Group determines classification of financial assets and liabilities on initial recognition. After initial recognition, no reclassification is made for financial assets which are equity instruments. For financial assets which are debt instruments, a reclassification is made only if there is a change in the business model for managing those assets. Changes to the business model are expected to be infrequent. The Group’s senior management determines change in the business model as a result of external or internal changes which are significant to the Group’s operations. Such changes are evident to external parties. A change in the business model occurs when the Group either begins or ceases to perform an activity that is significant to its operations. If the Group reclassifies financial assets, it applies the reclassification prospectively from the reclassification date which is the first day of the immediately next reporting period following the change in business model. The Group does not restate any previously recognised gains, losses (including impairment gains or losses) or interest. 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	t) 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 profit or loss, except for the effective portion of cash flow hedges, which is recognised in OCI and later reclassified to 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 - Hedges of a net investment in a foreign operation 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, as well as forward commodity contracts for its exposure to volatility in the commodity prices. The ineffective portion relating to foreign currency contracts is recognised as other expense and the ineffective portion relating to commodity contracts is recognised in other operating income or expenses. The Group designates only the spot element of forward contracts as a hedging instrument. 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 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 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	u) 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	v) 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)	w) 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	x) 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	y) 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 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.
New standards, interpretations and amendments	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, 2022 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) Onerous Contracts – Costs of Fulfilling a Contract – Amendments to IAS 37 In May 2020, the IASB issued amendments to IAS 37 to specify which costs an entity needs to include when assessing whether a contract is onerous or loss-making. The amendments apply a “directly related cost approach”. The costs that relate directly to a contract to provide goods or services include both incremental costs and an allocation of costs directly related to contract activities. General and administrative costs do not relate directly to a contract and are excluded unless they are explicitly chargeable to the counterparty under the contract. The amendments are effective for annual reporting periods beginning on or after January 1, 2022. These amendments had no impact on the consolidated financial statements of the Group as there were no onerous contracts. (b) Reference to the Conceptual Framework – Amendments to IFRS 3 The amendments replace a reference to a previous version of the IASB’s Conceptual Framework with a reference to the current version issued in March 2018 without significantly changing its requirements. The amendments add an exception to the recognition principle of IFRS 3 Business Combinations to avoid the issue of potential ‘day 2’ gains or losses arising for liabilities and contingent liabilities that would be within the scope of IAS 37 Provisions, Contingent Liabilities and Contingent Assets or IFRIC 21 Levies, if incurred separately. The exception requires entities to apply the criteria in IAS 37 or IFRIC 21, respectively, instead of the Conceptual Framework, to determine whether a present obligation exists at the acquisition date. The amendments also add a new paragraph to IFRS 3 to clarify that contingent assets do not qualify for recognition at the acquisition date. These amendments had no impact on the consolidated financial statements of the Group as there were no contingent assets, liabilities and contingent liabilities within the scope of these amendments arisen during the year. (c) Property, Plant and Equipment: Proceeds before Intended Use – Amendments to IAS 16 The amendment prohibits entities from deducting from the cost of an item of property, plant and equipment, any proceeds of the sale of items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognises the proceeds from selling such items, and the costs of producing those items, in profit or loss. These amendments had no impact on the consolidated financial statements of the Group as there were no sales of such items produced by property, plant and equipment made available for use on or after the beginning of the earliest period presented. (d) IFRS 9 Financial Instruments – Fees in the '10 per cent' test for derecognition of financial liabilities The amendment clarifies the fees that an entity includes when assessing whether the terms of a new or modified financial liability are substantially different from the terms of the original financial liability. These fees include only those paid or received between the borrower and the lender, including fees paid or received by either the borrower or lender on the other’s behalf. There is no similar amendment proposed for IAS 39 Financial Instruments: Recognition and Measurement. These amendments had no impact on the consolidated financial statements of the Group as there were no modifications of the Group’s financial instruments during the year. 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 which are not expected to have any material impact on the consolidated financial statements of the Group are disclosed below. The Group intends to adopt these new and amended standards and interpretations, if applicable, when they become effective. - Amendments to IAS 12 - Deferred Tax related to Assets and Liabilities arising from a Single Transaction (effective from January 1, 2023*) - Amendments to IAS 1 and IFRS Practice Statement 2 - Disclosure of Accounting Policies (effective from January 1, 2023*) - Amendments to IAS 8 - Definition of Accounting Estimates (effective from January 1, 2023*) - Amendments to IAS 1 - Classification of Liabilities as Current or Non-current (effective from January 1, 2024*) - Amendments to IAS 7- Supplier Finance Arrangements (effective from January 1, 2024*) - Amendments to IFRS 16 - Lease Liability in a Sale and Leaseback (effective from January 1, 2024*) * Effective for annual periods beginning on or after this date.

The Group undertook the impairment testing of Goodwill assigned to each Individual or Group of CGUs as at March 31, 2023 and 2022 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 (for wind segment) and past performance (for solar segment); operation and maintenance expenses are based on prevaling prices and adjusted for inflation; and discount rates are based on weighed average cost of capital. These assumptions are forward-looking and are affected by future economic and climatic conditions including wind speed.
