Key Billing Terms

Energy Charges
The cost of electricity consumed, calculated by multiplying units (kWh) by applicable slab rates.
Fixed Charges
A recurring charge for maintaining the distribution connection, often based on sanctioned load or a flat monthly fee.
Telescopic Slabs
Each unit is priced in sequence from the lowest slab upward until total consumption is covered.
Electricity Duty
A state government tax levied as a percentage of energy charges.
FAC (Fuel Adjustment Charge)
A variable surcharge to account for changes in fuel and power purchase costs.
Meter Rent
A fee for the electricity meter, though many domestic consumers are exempt.

Tips to Reduce Your Bill

  • Kerala's granular slabs mean small usage increases can bump you into a higher per-unit rate.
  • Use solar water heaters — Kerala's climate makes them highly effective.
  • Shift heavy appliance use (washing machine, iron) to off-peak if on time-of-day metering.
  • Insulate your home to reduce fan and AC usage during humid months.
