    The Kenya Electricity Generating Company PLC has announced the completion of the Olkaria 1 geothermal power station rehabilitation project, which successfully increased the facility generation capacity from 45 megawatts to 63 megawatts. This project serves as the centrepiece of a KSh 15.5 billion capital investment programme executed during the financial year leading up to June 2026. According to the utility, the strategic capital outlay is specifically designed to maintain the operational reliability of existing generation assets while simultaneously building out the new capacity required to support households, businesses, and broader economic growth across the country.

    During the review period, KenGen supplied 8,975 gigawatt hours of electricity to the national grid, meeting 57.2 percent of total national demand with more than 90 percent of that dispatched power originating from renewable sources. Managing Director and CEO Eng. Peter Njenga noted that Kenya has experienced a peak electricity demand of 2,549 megawatts, underpinning the critical need for dependable generation. Alongside the Olkaria 1 upgrade, the active project portfolio includes the proposed 42.5 megawatt Seven Forks solar plant, the redevelopment of the Gogo hydropower station, battery storage installations, and the proposed raising of the Masinga dam to improve water management.

    Financially, KenGen recorded a 6.4 percent rise in revenue to reach KSh 59.7 billion, while operating profit climbed by 4.1 percent to KSh 14.2 billion. Profit after tax experienced a minor decline of 1.2 percent to KSh 10.35 billion, a shift attributed to lower finance income as cash reserves were actively deployed into capital investments. Crucially, the company reduced its total borrowings by KSh 12.2 billion down to KSh 97.1 billion, strengthening its balance sheet. At the Annual General Meeting, shareholders approved a first and final dividend of KSh 0.75 per share for the year, scheduled for payment on or about January 21, 2027.

    Beyond immediate grid supply, KenGen is actively leveraging its geothermal resources to drive industrial growth at Olkaria in Naivasha. The company Green Energy Park has secured special economic zone status and designation as a customs controlled area, providing a structured framework to attract manufacturers, food processing facilities, and data centres close to direct sources of geothermal electricity and steam. Furthermore, the utility is expanding its commercial consultancy services through its G2G 2034 Strategy, offering technical expertise in geothermal drilling, resource assessment, engineering, and plant maintenance to diversify revenue streams away from pure electricity sales.

    Why This Matters

    The strategic trajectory of KenGen demonstrates how state-backed energy utilities in Africa can simultaneously manage heavy infrastructure outlays, balance sheet de-leveraging, and commercial diversification. By deploying significant capital into asset rehabilitation and renewable expansion, the utility directly addresses the infrastructure bottlenecks that constrain industrial productivity and commercial scaling. The simultaneous reduction in corporate borrowings underscores a disciplined approach to capital allocation, proving that long term capital expenditure in heavy power infrastructure does not necessarily require compromising financial stability or debt sustainability.

    The creation of the Green Energy Park with special economic zone status highlights an evolving regulatory and industrial integration model on the continent. By collocating heavy energy generation with manufacturing and data processing facilities, the initiative establishes a blueprint for localized industrialisation powered entirely by reliable renewable energy. This operational framework mitigates transmission losses while offering industrial tenants predictable energy pricing and customs advantages, thereby strengthening the country manufacturing base and insulating domestic industrial output from broader global supply chain shocks.

    Opportunities

    <>
    • Industrial Tenants and Manufacturers: Opportunities to establish operations within the Olkaria Green Energy Park, leveraging dedicated geothermal steam and electricity access backed by special economic zone incentives.
    • Engineering and Technical Contractors: Commercial prospects in upcoming generation projects, including the Seven Forks solar plant development, Gogo hydropower station redevelopment, and dam infrastructure works.
    • Financial Institutions and Lenders: Opportunities to engage with a strengthening corporate balance sheet as KenGen continues its debt reduction trajectory while funding large scale renewable energy assets.
    • Energy and Infrastructure Consultants: Potential partnerships arising from KenGen G2G 2034 Strategy, utilising the utility technical services in geothermal drilling and plant maintenance across the region.
