Geothermal energy is emerging as one of Africa’s most reliable sources of baseload green power, and Kenya is leading that charge. In a region where other renewables depend on weather, these players are building heat-to-electricity infrastructure that can run day and night.
Here are the Top 5 African Companies in Geothermal Electricity Generation, based on verified capacity, development role, and impact as of 2025:
— KenGen (Kenya): The largest geothermal power generator in Kenya, operating multiple major plants across the Olkaria geothermal field, with nearly 800 MW of installed geothermal capacity.
— Geothermal Development Company (GDC) (Kenya): A state-owned developer building and managing steam fields, drilling exploration wells, and supplying steam to private and public power producers.
— OrPower / Ormat Technologies (Kenya): Operates the OrPower 4 geothermal plant (Olkaria) and brings private-sector investment into Kenya’s geothermal power generation market.
— Globeleq (Kenya): An independent power producer backing the Menengai geothermal project, operating under a steam-purchase agreement for long-term output.
— Sosian Energy (Kenya): Runs Menengai III, a geothermal power plant developed in cooperation with local partners, expanding Kenya’s capacity in green, geothermal baseload power.
More African countries are exploring geothermal potential, but these five companies currently dominate geothermal electricity generation with verified activity, development scale, and proven impact.
