Quick answers to common questions
Most states use telescopic (progressive) slab tariffs — units in each range are charged only at that slab's rate. The bill also includes fixed charges, fuel surcharges, electricity duty, and sometimes subsidies.
It depends on consumption. Delhi offers free power up to 200 units/month with subsidy. Tamil Nadu gives first 100 units free. Karnataka's Gruha Jyothi provides up to 200 units free for eligible households.
Telescopic means only the units falling within each slab are charged at that rate. For example, 350 units in Maharashtra: first 100 at ₹4.43, next 200 at ₹8.06, and remaining 50 at ₹9.38.
Fuel and Power Purchase Cost Adjustment (FPPCA) is a variable surcharge per unit to recover changes in fuel costs. Maharashtra currently adds ₹0.80/unit.
Rates are indicative for FY 2025-26 based on SERC tariff orders. Actual bills may differ due to FAC revisions, meter type, time-of-day tariffs, and DISCOM-specific charges.
Gruha Jyothi provides up to 200 units of free electricity per month for eligible domestic consumers. If consumption exceeds 200 units, the full bill applies on all units.
Domestic consumers with subsidy get zero charges on energy for up to 200 units/month. Above 200 units, normal slab rates apply from the 201–400 band onwards.
A state tax on electricity consumption. Maharashtra charges 16%, Uttar Pradesh 5%, and Rajasthan 8% on energy charges plus fuel surcharge.
