Kenya Electricity Generating Company PLC (KenGen) has awarded a multibillion contract for the rehabilitation of Kenya’s oldest geothermal power plant, aiming to increase its output from 45 MW to 63 MW in a move to accelerate the country’s transition to green energy.

The electricity generator said the initiative is poised to elevate the power plant's operational efficiency and increase electricity generation output by up to 40% compared to existing conventional models whose first unit was commissioned in 1981 and has since been decommissioned.

In the tender, SEPCOIII Electric Power Construction Co., Ltd will be the EPC contractors whereas Toshiba Energy Systems and Solutions Corp. (Toshiba ESS) has been awarded the contract to supply steam turbines and generators for the three units of the power plant.

KenGen’s Managing Director and CEO, Eng. Peter Njenga, expressed his enthusiasm for the project: “The renovation of Olkaria I represents a historic milestone for KenGen as we continue our commitment to sustainable energy solutions. By leveraging the latest advancements in geothermal technology, we aim to not only enhance the performance of the plant but also set new standards for renewable energy production in Kenya.”

The modernisation project, scheduled for completion by December 2026, is designed to align with Kenya's broader energy objectives and the Vision 2030 initiative, which envisions a transition to 100% green energy by the end of the decade.

“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,” added Eng. Njenga.

KenGen CEO’s expressed confidence in the project citing resource availability and the company’s highly skilled expertise: “Having operated for more than 40 years, this confirms the sustainability of geothermal coupled with the skills set and human resource capabilities that KenGen has developed over the years, we are confident the project will be completed on time and within budget.”

Through this comprehensive renovation, KenGen aims to not only extend the operational lifespan of Olkaria I, but also establish a model for sustainable energy development that can be replicated across the region as Kenya angles to exploit the 10 000 MW of geothermal potential in the Rift Valey region of Kenya.

By prioritising innovation, efficiency, and environmental responsibility, KenGen is paving the way for a greener, more sustainable future for Kenya's energy landscape.
