Kenya continues to solidify its position as a geothermal powerhouse, with the latest energy sector figures revealing a robust performance for the second half of 2025.

Between July and December, geothermal energy remained a cornerstone of the national grid, contributing a significant 40.06% of the total energy supplied to the interconnected system.

This reliance on steam-powered electricity underscores the strategic importance of the Rift Valley’s volcanic resources in maintaining the country's energy security.

Total generation during this six-month window reached an impressive 3,127.76 GWh.

The data shows a steady, albeit fluctuating, monthly output that highlights the reliability of geothermal plants as base load facilities.

These plants are designed to run consistently, providing a stable foundation for the grid that is less susceptible to the seasonal variations that often affect hydro-generated power.

The period began with strong figures in July and August, recording 529.48 GWh and 527.94 GWh respectively.

While September saw a slight dip to 496.11 GWh, the sector demonstrated resilience with a recovery in October to 515.41 GWh.

November output remained stable at 498.40 GWh before the year closed on a high note in December, with production surging to a peak of 560.41 GWh.

This year-end spike represents the highest monthly output in the biannual cycle, signaling a strong operational finish for the 2025-26 financial year.

With geothermal energy accounting for nearly half of the nation's grid supply, the sector continues to be the primary engine driving Kenya's transition toward a sustainable and reliable energy future.
