How Kerala per-unit rates are set

The Kerala State Electricity Regulatory Commission publishes an annual tariff order specifying slab rates, fixed charges, fuel adjustment formulas, and electricity duty for each DISCOM. For domestic consumers in Kerala, KSEB uses a non-telescopic billing structure — meaning when your monthly use crosses a slab boundary, every unit is billed at the higher rate.

The headline per-unit rate is only the energy charge. Your full bill also includes a fixed charge (typically load-band based), Fuel & Power Purchase Cost Adjustment (FAC / FPPCA, set monthly) and an electricity duty of 10%. Together these can add 15–30% to the effective per-unit cost.

Tariffs are typically revised once a year, with mid-year FAC pass-through revisions for fuel cost volatility. We verify Kerala rates against the official tariff order every quarter. Last verified: 2026-04-22.

Kerala electricity rate — FAQs

Answers to the most common electricity bill questions in India.

What is the electricity unit rate in Kerala in 2026?
As per the latest SERC tariff order, domestic electricity rates in Kerala range from ₹3.25/unit (entry slab) to ₹8.80/unit (highest slab). Exact slab rates differ between DISCOMs — see the table on this page for KSEB.
How much does 1 unit (1 kWh) of electricity cost in Kerala?
1 unit = 1 kWh in every Indian state including Kerala. The cost of 1 unit at KSEB starts at ₹3.25 for the first slab and rises with consumption. Add fixed charges, FAC and electricity duty to get the effective per-unit cost. See the 1-unit kWh calculator for a full breakdown.
Why does the per-unit rate change as I use more electricity?
Kerala uses a non-telescopic slab structure for domestic consumers. Once your monthly consumption crosses a slab boundary, all your units are charged at the higher slab rate — so it pays to stay just below a slab edge.
What is the commercial electricity rate in Kerala?
Commercial (LT) rates in Kerala typically start at ₹9.10/unit and go up to ₹9.10/unit, plus a higher fixed charge per kW than domestic. Industrial tariffs are usually flat-rate.
Do these unit rates include fixed charges and FAC?
No — the per-unit rates shown are the energy charge only. Your actual bill also includes a fixed charge (₹/kW of sanctioned load), Fuel Adjustment Charge (FAC, varies monthly), electricity duty (a percentage of energy charges), and sometimes meter rent. The effective per-unit rate is typically 15–30% higher. Use the bill calculator for the all-in figure.
