Kenya’s Power Cost Trap Keeps Businesses Exposed to Fuel and Forex Shocks

Kenyan electricity consumers have spent much of 2026 carrying a persistent layer of variable charges on top of the base tariff, even though those charges have not moved in a straight line. In October, the Energy and Petroleum Regulatory Authority set the Fuel Energy Cost Charge at KSh3.22 per kilowatt hour, the Foreign Exchange Fluctuation Adjustment at about KSh0.87 and the Water Resources Management Authority levy at KSh0.0134, bringing the three main monthly pass through charges to roughly KSh4.10 per unit. That followed about KSh4.16 in September and KSh4.70 in August, reinforcing the public impression that power bills remain under pressure even when individual components rise and fall from one month to the next. The monthly notices are often interpreted as a sequence of fresh tariff increases, but that is not how the mechanism works. EPRA recalculates the fuel, foreign exchange and water related components according to the underlying costs facing the electricity sector, and the new month’s rates replace the previous month’s adjustments rather than stacking permanently on top of them. The burden on consumers comes from the fact that these charges remain embedded in the bill month after month and can change quickly depending on thermal generation, currency movements and hydrological conditions. For a household using modest volumes of electricity, those movements are noticeable. For manufacturers, hotels, cold storage operators, data centres and other large consumers, a change of even one shilling per unit can materially alter monthly operating costs. Year-on-Year Data Shows a More Complicated Picture A year-on-year comparison gives a more nuanced picture than the monthly headlines suggest. In May 2025, the Fuel Energy Cost Charge, forex adjustment, and WRMA levy combined to about KSh4.97 per kWh, compared with roughly KSh4.18 in May 2026, a decline of around 16 percent. June showed a similar pattern, falling from about KSh4.52 per unit in 2025 to KSh3.87 in 2026. July narrowed the difference to roughly 2 percent, while August moved in the opposite direction, rising from about KSh4.23 in 2025 to KSh4.70 in 2026. September then eased again, from around KSh4.42 to KSh4.16, and October fell from approximately KSh5.24 in 2025 to KSh4.10 in 2026. Month2025 Fuel, Forex and WRMA2026 Fuel, Forex and WRMAApprox.

The more accurate conclusion is that Kenyan consumers continue to carry a substantial and volatile variable cost burden whose level can move sharply within a short period. Fuel Costs Remain The Largest Source Of Volatility The fuel component remains the largest moving part of the bill and explains much of this volatility. In August 2026, the Fuel Energy Cost Charge reached KSh3.51 per unit, accounting for roughly three quarters of the combined monthly adjustment. It fell to KSh3.00 in September before rising again to KSh3.22 in October. Kenya’s electricity system is often associated with geothermal, hydropower and wind, but thermal generation still matters, particularly when the system requires fuel based plants to meet demand or when hydropower output weakens. Consumers therefore remain indirectly exposed to imported fuel prices even though the country has one of the stronger renewable generation mixes in Africa. The opposite is also true. Strong hydropower output, geothermal availability or increased production from other lower cost sources can reduce reliance on thermal generation and pull down the fuel adjustment. Kenya has therefore reduced its exposure to imported fuel through renewable generation without eliminating it. Foreign Exchange Risk Still Reaches The Consumer The foreign exchange adjustment adds a second layer of uncertainty. Kenya’s power sector carries foreign currency denominated obligations through power purchase agreements, equipment financing, debt and other contractual arrangements involving Kenya Power, KenGen and independent power producers. When the shilling moves against the currencies underlying those obligations, EPRA passes part of the resulting gain or loss into retail electricity prices. The adjustment moved from KSh1.1033 per kWh in May 2026 to KSh0.7154 in June, then jumped to KSh1.4841 in July before moderating to KSh1.1777 in August and falling further by October. A consumer can therefore use exactly the same amount of electricity in two different months and receive a different bill because the financial structure of the electricity sector has changed around them. For businesses consuming large volumes of power, this turns currency movements into a direct operating cost. Household Bills Confirm Pressure, But Not A Straight Increase The household data confirms that the pressure is real but uneven. Kenya National Bureau of Statistics figures show that the national average cost of 200 kWh of electricity rose from KSh5,539.54 in August 2025 to KSh5,658.80 in August 2026, an increase of about 2.2 percent. A 50 kWh purchase increased by about 2.4 percent over the same period. By September, however, the direction had reversed, with the average cost of 200 kWh falling to around KSh5,533.80 compared with KSh5,597.16 a year earlier. Electricity therefore moved from being modestly more expensive year on year in August to slightly cheaper in September, even though public frustration over monthly charges remained high. That frustration also reflects the wider cost of living environment. Electricity bills are paid alongside transport, food, rent, school expenses and other essentials, so consumers do not experience them in isolation. For lower income households, the relevant issue is not whether the electricity component rose by 1 percent or 2 percent in statistical terms, but whether the total monthly budget has enough room to absorb another variable charge. Businesses Face A Predictability Problem For businesses, predictability matters as much as the absolute price. A manufacturer can plan wages, negotiate raw material contracts and estimate production volumes, but it has less control over how fuel dispatch, hydrology and exchange rate movements will alter electricity costs in the next billing cycle. That uncertainty is particularly important for power intensive industries where electricity is a meaningful part of the cost structure. Cement producers, steel processors, cold chain businesses, hospitality operators, data centres and large commercial buildings can all see material differences in operating expenses when the effective tariff moves by even a small amount. This is why Kenya’s electricity competitiveness cannot be assessed using the base tariff alone. Investors and businesses care about the final effective price after all adjustments, the reliability of supply and the extent to which future costs can be forecast. The Viral Monthly Figures Need More Careful Reading The widely circulated sequence of electricity charges from May to October 2026 captures genuine pressure but does not always compare identical components. May, June, August, September and October figures broadly represent the combined fuel, forex and WRMA charges. July’s commonly quoted KSh5.18 per unit figure, however, includes an additional inflation adjustment of about KSh0.48 per unit. Excluding that component, July’s comparable fuel, forex and WRMA total was closer to KSh4.70. That matters because using the higher July figure alongside months that exclude the inflation adjustment exaggerates the apparent spike. The same caution applies to headlines claiming that electricity “went up again” in October. The fuel charge did increase from September to October, moving from KSh3.00 to KSh3.22 per unit, but the combined fuel, forex and water adjustment actually edged down from about KSh4.16 to KSh4.10 because the foreign exchange component fell. One line item can rise while the overall variable burden declines. The Uchumi360 Insight The broader lesson from the 2026 data is that Kenya’s electricity problem is not a simple story of tariffs climbing month after month. The more persistent issue is exposure to costs that consumers cannot influence and businesses cannot fully predict. Fuel prices, hydrological conditions and foreign currency obligations continue to move through the power system and eventually appear on the electricity bill. In most of the months reviewed, the 2026 variable charges were actually lower than a year earlier, but they still remained substantial enough to affect household budgets and business costs. Kenya has built one of the region’s strongest renewable generation bases, but the monthly EPRA adjustments show that the country has not yet insulated electricity consumers from fuel and foreign exchange risk. The monthly notices are therefore not six separate tariff increases stacked on top of one another. They are repeated evidence that a meaningful share of Kenya’s electricity price remains tied to costs that can change rapidly outside the control of the consumer. FAQ Are Kenya’s electricity charges increasing every month? No. EPRA recalculates fuel, foreign exchange and water related pass through charges periodically. The rates can rise or fall and replace the previous month’s adjustment rather than accumulating permanently. How much are the October 2026 electricity adjustments? The October fuel, foreign exchange and WRMA charges amount to approximately KSh4.10 per kWh, including KSh3.22 in fuel costs, about KSh0.87 in foreign exchange adjustment and approximately KSh0.0134 in the water levy. Are electricity charges higher than in 2025? It depends on the month. The three main pass through charges were lower year on year in May, June, July, September and October 2026, but higher in August. How much has an actual household electricity bill changed? KNBS data shows the national average price of 200 kWh was approximately 2.2 percent higher year on year in August 2026, but around 1.1 percent lower year on year in September. Why does EPRA impose a Fuel Energy Cost Charge? The charge passes changes in the cost of fuel used by thermal electricity generators into retail electricity prices. It varies according to fuel costs and the amount of thermal generation dispatched. Why is there a foreign exchange charge on electricity? Kenya’s power sector carries foreign currency denominated obligations through power purchase agreements, equipment, financing and other contracts. Exchange gains and losses are reflected through EPRA’s foreign exchange adjustment.
