Electricity Unit Rates in India

A "unit" on your electricity bill is exactly 1 kilowatt-hour (kWh). What you pay per unit depends on your state's regulatory commission, your distribution licensee (DISCOM), the slab your monthly consumption falls into, and your consumer category — domestic, commercial or industrial.

Most Indian DISCOMs use a telescopic slab structure for domestic consumers: the first N units are charged at the lowest rate, the next bracket at a higher rate, and so on. A few states (notably Kerala for some categories) use non-telescopic billing, where crossing a slab boundary reprices all units at the higher rate.

The headline per-unit slab rate is only the energy charge. Your actual all-in cost per unit is higher because of the fixed charge on sanctioned load (₹/kW/month), the Fuel & Power Purchase Cost Adjustment (FAC / FPPCA) which passes monthly fuel cost variation through to consumers, and electricity duty — a state-level percentage levy that ranges from about 5% to 25% depending on the state and consumer category. Some states also provide subsidies for low-consumption households (e.g. Punjab, Tamil Nadu, Delhi, Karnataka), which reduce the effective per-unit rate.

To find your DISCOM's exact rate, pick your state above and then drill into the DISCOM page. To get a full all-in bill rather than just the rate, use our main bill calculator or jump straight to the DISCOM-specific bill calculator from any unit-rate page.
