Estimate your Delhi electricity bill: DERC slabs, fixed charge, surcharges, FPPAS, electricity tax and the 200-unit subsidy.
Quick answer
In Delhi, domestic power is billed in slabs: ₹3.00 a unit for the first 200 units, ₹4.50 for 201–400, ₹6.50 for 401–800, ₹7.00 for 801–1,200 and ₹8.00 above 1,200. On top come a fixed charge based on your sanctioned load, an 8% regulatory surcharge, a 7% pension trust surcharge, the monthly FPPAS and 5% electricity tax. Households that have opted for the Delhi Government subsidy pay nothing up to 200 units a month and get 50% off (up to ₹800) between 201 and 400 units.
