Trend of the hydro energy generated in Kenya: Financial Year 2020/21 to 2024/25

The generation of hydro energy in Kenya—which is fundamentally tied to rainfall patterns and electricity demand—experienced significant fluctuations between the financial years 2020/21 and 2024/25.

Hydro generation typically peaks during the long rainy season, between April and August.

The financial year 2020/21 recorded the highest output in the five-year period, generating 4,142.18 GWh.

Output then saw two consecutive years of decline, dropping to 3,348.71 GWh in 2021/22, and reaching a low point of 2,569.18 GWh in 2022/23.

This low figure suggests a period of diminished rainfall or reservoir levels. However, the subsequent years demonstrated a strong recovery.

Generation rose to 3,377.58 GWh in 2023/24 and further increased to 3,503.47 GWh in the 2024/25 financial year.

This upward trend in the final two periods indicates improving hydrological conditions and underscores the continued critical role of hydro power in Kenya’s energy mix.
