Kenya Electricity Generating Company (KenGen) has reported that its Olkaria I geothermal expansion project in the Great Rift Valley has reached 70 percent completion on key milestones, with the company expressing confidence that the first turbine will be commissioned by June 2026, adding 63 megawatts of clean baseload power to Kenya’s national grid.
70% Completion and the Path to First Turbine Commissioning
KenGen disclosed in June 2026 that the Olkaria I expansion had cleared 70 percent of its key project milestones. “We are on course to bring the first turbine online within our targeted window,” said a KenGen official. Geothermal plants operate at very high capacity factors — often above 85 percent — compared with intermittent renewables such as wind and solar.
What Comes Next
Following commissioning of the first turbine, KenGen and KETRACO must complete grid-connection testing and synchronisation before commercial generation begins. KenGen has signalled further expansion ambitions at additional Rift Valley sites.
