Tips to Reduce Your Kerala Electricity Bill
1. KSEB bills bimonthly — track your monthly consumption carefully to avoid crossing into higher slabs over a 2-month period.
2. Kerala’s climate means fans run year-round — switching to BLDC fans (28W) from conventional fans (75W) saves significantly over 12 months.
3. KSEB offers subsidised tariff for Below Poverty Line (BPL) domestic consumers under LT-1B category — check eligibility at your KSEB section office.
4. Invest in rooftop solar — KSEB’s net metering policy allows you to export surplus power and offset your bill.
5. Water heating is a major electricity cost in Kerala — switch to solar water heaters which are particularly effective given Kerala’s sun hours.
6. Apply for PM Surya Ghar Muft Bijli Yojana — Kerala residents can avail central government subsidy of up to ₹78,000 on rooftop solar.
