The Central Electricity Regulatory Commission (CERC) issued a suo motu order directing that monthly tariffs or charges must be adjusted or refunded from the date the Goods and Services Tax reduction event occurs, affirming that renewable energy generators must pass on the benefit of lower tax rates to procurers. To enable this, generating stations must furnish invoices and auditor-certified statements demonstrating a clear one-to-one correlation between project expenditure and the invoices raised. The Commission has instructed all parties to complete this reconciliation before approaching it for tariff determination under Change in Law provisions, as per the Electricity (Timely Recovery of Costs due to Change in Law) Rules, 2021, and Section 63 of the Electricity Act, 2003.
