How is Kerala Electricity Bill Calculated?
Kerala State Electricity Regulatory Commission (KSERC) prescribes a telescopic tariff structure for domestic consumers under LT-1A up to 250 units/month, transitioning to non-telescopic rates beyond 250 units. For example, if a home in Thiruvananthapuram, Kochi, Kozhikode, or Thrissur consumes 200 units with a 1 kW connected load:
- First 50 units @ ₹3.25 = ₹162.50
- Next 50 units (51 to 100) @ ₹4.05 = ₹202.50
- Next 50 units (101 to 150) @ ₹5.10 = ₹255.00
- Remaining 50 units (151 to 200) @ ₹6.40 = ₹320.00
- Total Energy Charges: ₹940.00
- Fixed Demand Charges: 1 kW × ₹90 = ₹90.00
- Electricity Duty (10%): (₹940 + ₹90) × 10% = ₹103.00
- Fuel Surcharge & Meter Rent: ₹25.00
- Estimated Total Monthly Bill: ₹1,158.00 (Approx ₹1,158)
Telescopic vs Non-Telescopic Billing in Kerala
Under KSEB tariff guidelines:
- Up to 250 units/month: Telescopic billing applies — each slab is charged only for the units that fall within that specific slab bracket.
- Above 250 units/month: Non-telescopic billing applies — entire units consumed from 0 onwards are charged at higher uniform flat slab rates, which leads to a noticeable jump in monthly bills.
- Keeping your monthly consumption below 250 units helps you take full advantage of telescopic savings.
