💡 Things to Keep in Mind Before Calculating Kerala Electricity Bill

1. Check Billing Period

Verify whether your DISCOM (KSEB (Kerala State Electricity Board)) bills monthly (about 30 days) or bi-monthly (about 60 days). Kerala uses a bi-monthly billing cycle.

2. Understand Sanctioned Load (kW)

Fixed charges are modeled at ₹55 per kW of sanctioned load for the configured tariff. Your actual bill may use kVA, a different load basis, or category-specific charges.

3. Verify Fuel Surcharge (FAC/FPPPA)

The configured adjustment is ₹0.1/unit. Fuel or power-purchase adjustments can change by tariff order or billing period, so treat this as the value currently configured in the calculator.

4. State Subsidy Eligibility

Check if you qualify for Kerala government zero bill schemes (Telescopic pricing up to 250 units monthly; non-telescopic rates apply above 250 units.).
