The 45MW Olkaria 1 (Units 1, 2 and 3) Geothermal Power Plant is located at the Olkaria geothermal field in the Rift Valley. This was the first geothermal power plant in Africa commissioned in 1980.

Due to the normal wear and tear experienced by the plant over years of operation, KenGen wishes to restore the plant to its former glory and is currently in the process of procuring a Contractor to carry out the rehabilitation works.

Upon completion of the project, the plant will be upgraded from the current 45MW to 50.7MW.
