KSEB scored 63.25 and ranks 24 of 54 state and private distribution utilities.
The rating scores the utility’s financial and operational performance — AT&C losses, billing and collection efficiency, the gap between what supply costs and what it earns, and the regulatory support the utility gets. It is not a measure of supply reliability or customer service, and it does not affect your tariff.
The standard domestic connection. Fixed charge runs ₹50/month at low consumption up to ₹310/month above 500 units.
LT-I Domestic — three phase
Same energy rates as single phase; the fixed charge is higher at every band (₹130 to ₹310/month).
LT-I Domestic — BPL (≤ 1000 W, ≤ 40 units/month)
BPL consumers with connected load of and below 1000 watts consuming up to 40 units a month: ₹1.50/unit and no fixed charge. Crossing either limit moves the connection to the ordinary domestic schedule.
ℹ️ Kerala switches billing regime at 250 units a month. At or below 250 the slabs are telescopic — each band at its own rate. Above 250 the schedule is non-telescopic: a single rate is applied to every unit on the bill, so a 251-unit bill costs noticeably more than a 250-unit one, and the jump repeats at 300, 350, 400 and 500 units. The fixed charge steps up on the same boundaries. The KSERC schedule is expressly exclusive of Electricity Duty, cesses and other State levies, which are notified separately. Domestic bills here add the 10% duty; cesses and other levies are not modelled, so your printed bill may carry a little more.

Who each rate applies to

ℹ️ The gazette marks LT-VII(A) energy charges "Non telescopic" in terms: whichever band your monthly consumption falls in, that one rate applies to every unit. Crossing 500 units takes the entire bill to ₹9.40/unit. The fixed charge is per kW of connected load, rounded up to the next whole kW. The KSERC schedule is expressly exclusive of Electricity Duty, cesses and other State levies, which are notified separately. Domestic bills here add the 10% duty; cesses and other levies are not modelled, so your printed bill may carry a little more.
Estimate your KSEB bill
Enter your units and sanctioned load for an itemised KSEB estimate. The result breaks
the bill into energy charge, fixed or demand charge, FPPA, duty,
and late-payment surcharge where applicable.
Domestic supply. The bracket in each option is the eligibility
limit — pick the one your connection actually falls under, because the rates differ
sharply between them. For commercial supply, time-of-day, solar export or arrears, the
full calculator carries every field.
KSEB FPPA — latest verified rate and trend
Latest verified KSEB FPPA (Fuel and Power Purchase Adjustment)
Typical domestic examples for a 2 kW LT-I (Domestic) connection, computed with the same engine as the calculator. Use them as a quick sanity check; your actual bill changes with sub-category, arrears, FPPA, duty and billing-period length.
The slab-wise price of the units consumed during the billing period. In telescopic slabs, each band is billed at its own rate.
Fixed charge
A monthly charge linked to sanctioned load, connected load, billing demand or consumer category. It applies even when usage is low.
Electricity duty
A statutory government levy. Depending on the state, it may apply on energy charges, fixed charges, or selected bill components.
FPPA (Fuel and Power Purchase Adjustment)
Fuel and power-purchase adjustment. It changes more often than the base tariff and may appear as a charge or a credit.
Arrears
Unpaid balance, corrections, security-deposit adjustments or previous-cycle amounts carried into the current bill.
LPSC
Late Payment Surcharge on overdue amounts. Check the due date and pay through the official DISCOM channel to avoid it.
