How Kenya’s electricity supply changed from 2021 to 2025
Kenya’s geothermal plants produced 5,982 GWh in 2025. Hydro generation fell from the previous year, while imports increased to 1,721 GWh. The full series separates locally generated power from cross-border supply.

Imports and solar grew between 2021 and 2025. Geothermal remained the largest source of domestic generation.
Geothermal led domestic generation
KNBS reports 5,981.6 GWh of geothermal electricity in 2025, up from 5,551.0 in 2024. That made it the largest domestic source in the table. The 2023 geothermal figure, 6,032.1 GWh, remained slightly above the provisional 2025 value. Source 1
Hydro and thermal moved in different directions
Hydro generation fell from 3,630.7 GWh in 2024 to 3,462.3 GWh in 2025. Thermal generation increased from 1,129.5 to 1,480.2 GWh. KNBS links the thermal increase in part to the return of the Muhoroni Gas Turbine. Source 1
Imports were nearly six times their 2021 level
Imports increased from 288.0 GWh in 2021 to 1,721.1 in 2025. The survey cites cross-border power exchange with Tanzania and the commissioning of the Namanga line as factors in the most recent increase. The chart lists imports separately from Kenyan plants. Source 1
Generation and capacity have different units
A gigawatt-hour measures energy produced or delivered over time. A megawatt measures how much power a plant can supply at a particular moment. To compare utilisation of different projects, use their installed capacity and actual output over the same period. Source 1
