Kenya’s electricity bills remain heavily influenced by two monthly charges that can rise even when much of the country’s electricity comes from renewable sources: the Fuel Energy Cost Charge (FECC) and the Foreign Exchange Fluctuation (FEF) adjustment. The two charges reflect costs incurred elsewhere in the electricity system and passed through to consumers by the regulator, meaning changes in fuel prices, thermal power dispatch and the Kenya shilling can quickly show up on monthly bills.
The FECC is designed to recover the cost of fuel used by thermal generators. When demand rises, hydropower output falls or variable renewable generation is insufficient, Kenya relies more heavily on diesel and heavy-fuel-oil plants to maintain supply and grid stability. Because these plants require imported fuel, higher fuel prices and the relatively high fuel consumption of some older thermal units translate into a higher cost per kilowatt-hour. In recent months, the FECC has been around KSh3.06–3.51 per kWh, making it a significant component of the final electricity price.
The FEF adjustment creates a different vulnerability: the electricity sector has substantial exposure to foreign currencies while consumers pay their bills in shillings. Power-purchase agreements, project financing, imported fuel, equipment and other obligations can be denominated in US dollars or linked to exchange rates. When the shilling weakens, the cost of meeting these obligations rises in shilling terms. For August 2026, EPRA reported about KSh1.353 billion in net foreign-exchange losses across KenGen, Kenya Power and independent power producers, translating into an FEF adjustment of roughly KSh1.18 per kWh.
The important point is that these costs are not simply absorbed by generators or Kenya Power. Under Kenya’s tariff framework, actual fuel and foreign-exchange costs are periodically recovered through adjustments to consumer bills. This creates a direct link between events outside a household or factory’s control such as global oil prices or movements in the shilling and the price paid for electricity. A country can therefore have a relatively clean generation mix while consumers remain exposed to fossil-fuel and currency-related costs elsewhere in the system.

This highlights why Kenya’s electricity challenge cannot be solved simply by adding more renewable generation. More geothermal, wind and solar can reduce dependence on expensive thermal generation, but the benefits will be limited if the wider system remains exposed to high financing costs, foreign-currency obligations and inefficient grid operations. Reducing the frequency of thermal dispatch, strengthening the shilling exposure management of power contracts and improving the efficiency of the grid would do more than simply add megawatts, they could help turn Kenya’s clean-energy advantage into lower and more predictable electricity bills.
