The order was received from SEPCOIIII Electric Power Construction Co. Ltd., the chosen EPC contractor for the project. Both contracts were awarded through a tender process.

Plans for the uprating of Olkaria I were first announced in 2022 as part of a wider rehabilitation plan of KenGen’s existing geothermal power plants to increase their capacities. The 45-MW Olkaria I holds the distinct position of being the oldest geothermal power plant in Kenya and has been operating since 1981. In mid-2023, Olkaria I was officially shut down to give way to the two-year rehabilitation plan.

The steam turbines and generators will be shipped from Toshiba to the site by December 2025. The modernization project is scheduled for completion by 2026.

Toshiba and KenGen had previously signed an MOU that anticipates a partnership of Operation and Maintenance (O&M) services for geothermal power plants in developing countries including East African countries through a combination of KenGen and Toshiba ESS’s know-how and networks.

“As the oldest geothermal power plant in Africa, Olkaria I holds significant historical importance and stands as a testament to Kenya’s pioneering efforts in renewable energy production and therefore the excitement for us to have this power plant back on the grid,” said Eng. Peter Njenga, KenGen Managing Director and CEO.

“I’m pleased that we can contribute to energy stability in Kenya by providing our equipment and services. Toshiba ESS will continue to provide optimal products and solutions to meet customer needs through its lineup of small to large geothermal steam turbines and generators with power outputs ranging from 1 MW to 200 MW. Aiming for the further clean energy indispensable for the realization of a sustainable society, we will contribute to the realization of a carbon neutral society by providing geothermal power plant services both in Japan and overseas,” added Shinya Fujitsuka, Director and Vice President of the Power Systems Division at Toshiba ESS.
