Electricity Bill Calculator — Kenya
Estimate a KPLC bill the way it is actually built: the base energy charge from the EPRA Schedule of Tariffs, the demand charge for commercial and industrial customers, the monthly gazetted pass-through charges (fuel, forex, inflation and the water levy), and the taxes and levies (VAT, REP and EPRA levies) — line by line, for any customer category from domestic lifeline to a 220 kV industrial intake.

Estimate only, using the Schedule of Tariffs 2023 (2025/26 values, still in force) and the gazetted pass-through charges for the selected month. Actual bills can differ through meter-reading dates spanning two tariff months, lifeline placement by 3-month rolling average, time-of-use rates, security deposits, arrears or reconnection fees. Verify against your KPLC bill or the EPRA tariff calculator.
How a Kenyan electricity bill is built
- Base energy charge. The Schedule of Tariffs 2023 (the 2025/26 values remain in force — the proposed 2026–2029 review was withdrawn in June 2026) sets the rate per kWh. Domestic and small-commercial customers are banded by total monthly consumption — lifeline up to 30 units, ordinary 31–100, and above 100 — and since April 2023 the bands are not telescopic: your total consumption selects one band, and that single rate applies to every unit. In practice KPLC assigns the band using a 3-month rolling average, which is why token values shift between months.
- Demand charge. CI customers additionally pay for their maximum demand in kVA — from KES 1,100/kVA at 415 V down to KES 200/kVA at 220 kV. Because it is billed in kVA, not kW, a poor power factor directly inflates this line; correcting to about 0.95 with capacitor banks is often the fastest saving on an industrial bill.
- Pass-through charges. Every month EPRA gazettes the Fuel Energy Cost Charge, the Foreign Exchange Fluctuation Adjustment, the Inflation Adjustment (revised every six months) and the WRMA water levy. These apply per kWh to all categories and are the reason bills move even when the base tariff does not. The calculator ships with recent months and accepts custom values from any gazette or bill.
- Taxes and levies. The REP levy adds 5% of the base energy charge, the EPRA levy adds 3 cents/kWh, and VAT at 16% applies to the base charges and the fuel, forex and inflation adjustments (but not to the levies themselves).
Assumptions and limits
- Time-of-use (peak/off-peak) rates for CI and e-mobility customers are not yet modelled — TOU can roughly halve the energy rate for off-peak consumption and is worth a dedicated assessment.
- Meter-reading periods that span two tariff months, arrears, security deposits and reconnection fees are outside the estimate.
- Rates current as at the July 2026 gazette notices; the CI4, CI5 and e-mobility base rates should be verified against the latest schedule for contractual use.
