Delhi consumers likely to see higher electricity bills as DERC clears surcharge hike

Delhi residents are likely to face a modest increase in electricity bills after the Delhi Electricity Regulatory Commission (DERC) approved higher Fuel and Power Purchase Adjustment Surcharge (FPPAS) limits for power distribution companies. The surcharge revision, approved for April 2026, allows discoms to recover higher power procurement costs arising from increased fuel prices and global market uncertainties. The largest impact is expected to be on consumers served by BSES Yamuna Power Limited (BYPL) in east and central Delhi.

For a household with a sanctioned load of 2 kilowatts and monthly consumption of 600 units, the bill in BYPL areas may increase by approximately ₹170, rising from about ₹3,766 to ₹3,936. Consumers in areas served by BSES Rajdhani Power Limited (BRPL) may see an increase of around ₹102, with bills rising from approximately ₹3,850 to ₹3,952 for similar consumption levels. Consumers served by Tata Power Delhi Distribution Limited (TPDDL) are unlikely to experience any significant change because the approved surcharge increase for that utility is marginal.

The FPPAS mechanism enables power distribution companies to recover additional costs incurred due to fluctuations in electricity generation and procurement expenses. Electricity tariffs are calculated on projected power purchase costs, but actual expenses can vary because of changes in coal prices, fuel imports, transportation charges, and market conditions. The surcharge allows these additional costs to be recovered without waiting for a formal tariff revision.

DERC approved the steepest increase for BYPL, raising its permissible surcharge from 11.71 per cent to 17.43 per cent. BRPL was allowed to increase its surcharge from 14.51 per cent to 17.94 per cent, while TPDDL's approved surcharge rose marginally from 15.99 per cent to 16 per cent. The regulator rejected requests by BRPL and BYPL for significantly higher recoveries of 31.55 per cent and 35.26 per cent respectively, but allowed limited increases after reviewing power purchase costs.

The latest order also relaxes an earlier ceiling that restricted FPPAS recovery to 10 per cent in a billing cycle. DERC had already granted special permission between January and February for discoms to exceed that cap. The new framework further permits recovery of deferred costs in future billing cycles if immediate recovery is restricted by surcharge limits. Officials clarified that consumers receiving Delhi government electricity subsidies will not be affected because the subsidy is linked to units consumed rather than the total bill amount.
