Trends in Kenya's wind energy generation

Kenya's wind energy generation has seen fluctuating output over the five financial years from 2020/21 to 2024/25.

Starting at 1,700.45 GWh in 2020/21, production steadily climbed to a high of 2,201.72 GWh in the 2022/23 financial year.

However, the trend reversed sharply in the following year, with generation dipping significantly to 1,798.59 GWh in 2023/24.

The sector showed a moderate recovery in the final year of the period, rising back to 1,907.57 GWh in 2024/25.

These variations are attributed to wind resource patterns that have an inverse correlation with rainfall patterns. Simply put, the periods of heavy rainfall, such as those typically experienced in May, often bring with them low wind speeds.

This phenomenon directly affects the efficiency of wind farms and accounts for the observed year-on-year changes in the nation's energy output. The data highlights the challenge of integrating weather-dependent renewable energy sources into the national grid.
