Geothermal is the single largest source of Kenya's electricity - about 47 percent in 2023, the latest full-year figure from the IEA - drawn from the Olkaria field in the Rift Valley, the largest geothermal complex in Africa, run by KenGen.
Kenya turned to the heat beneath the Rift Valley because it is baseload power that holds when drought idles the country's hydro dams.
KenGen has drilled the Olkaria field for four decades, making geothermal the backbone of a grid that now runs largely on renewables.
