The Delhi Electricity Tariff FY 2025–26 is regulated by the Delhi Electricity Regulatory Commission (DERC). Base electricity tariffs remain unchanged for FY 2025–26; however, consumers are required to pay Power Purchase Adjustment Cost (PPAC), which varies by DISCOM and generally ranges between 7% and 10% of the electricity bill. Electricity distribution in Delhi is managed by three DISCOMs: BSES Rajdhani Power Limited, BSES Yamuna Power Limited, and Tata Power Delhi Distribution Limited.
