(i)
Modification of contractual cash flows

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

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

Unwinding income on these trade receivables of INR 83 (March 31, 2025: INR 301; March 31, 2024: INR 504) is recognised as "Unwinding income of financial assets" under 'Finance income'.
