Kenya’s renewable energy sector is unusual because it does not depend on a single weather-driven resource. Geothermal plants provide continuous generation from the Great Rift Valley, hydropower supplies flexible electricity when rainfall allows, large wind farms serve the national grid, and solar power supports both utility-scale generation and off-grid access. This combination has made Kenya one of Africa’s leading renewable electricity markets.
Renewable sources produced nearly 90% of Kenya’s electricity in 2023. Geothermal accounted for approximately 47% of generation, followed by hydropower at 21%, wind at 16% and solar at 4%. The precise balance changes from year to year, particularly because hydropower output is affected by rainfall, but the underlying system remains strongly renewable.
Kenya’s next challenge is therefore different from that faced by countries that are only beginning to replace fossil fuels. It must expand a relatively clean power system while improving reliability, connecting remaining households, supporting industrial demand and avoiding investments that leave the grid with more generating capacity than it can use efficiently.
The Great Rift Valley Gives Kenya a Geothermal Advantage
Geothermal energy is the foundation of Kenya’s renewable power system. Underground heat associated with the East African Rift creates high-temperature resources that can be developed for electricity generation, particularly around Olkaria near Lake Naivasha. Unlike solar and wind, geothermal plants can operate throughout the day and are not directly dependent on rainfall.
This reliability gives geothermal power a central role in balancing Kenya’s electricity supply. It reduces the need to run oil-fired thermal plants when hydropower output falls and provides a stable base around which wind, solar and imported electricity can be managed.
Kenya had approximately 944 MW of installed geothermal capacity in 2024. Much of it is operated by the state-controlled Kenya Electricity Generating Company, commonly known as KenGen, although independent producers also participate in the sector. KenGen’s geothermal portfolio includes several Olkaria plants and wellhead generating units that use steam from individual wells while larger projects are developed.
Expansion remains a national priority. Kenya’s 2025–2030 National Energy Compact sets a target of about 1,681 MW of geothermal capacity by 2030. KenGen has also outlined a US$1.8 billion drilling and development opportunity involving 42 new wells and approximately 200 MW of additional generation.
The economics of geothermal development are attractive once a productive field is operating, but exploration and drilling require substantial early investment. Developers must spend money before they know exactly how much commercially usable steam a reservoir will provide. Public financing, development-bank support and government-backed exploration have therefore been important to Kenya’s progress.
Hydropower Still Matters, but Rainfall Changes Its Contribution
Hydropower remains another major component of Kenya’s renewable system. Installed hydro capacity stood at approximately 872 MW in 2024, with KenGen operating large stations along the Tana River and in other parts of the country.
Hydropower generation can respond to changes in demand more easily than geothermal plants, making reservoirs valuable for system balancing. However, drought and changing rainfall patterns can reduce output. Hydropower’s contribution to generation fell to 19.33% in the 2022/23 financial year before recovering to 24.81% in 2023/24.
This variability explains why geothermal development has been so strategically important. A system that depended more heavily on hydropower would be exposed to prolonged dry periods and could require greater use of imported electricity or thermal generation. Kenya’s mixture of geothermal, hydro, wind and solar reduces that risk, although it does not remove it.
The government plans to increase hydropower capacity to approximately 1,403 MW by 2030. Future development may include conventional projects, smaller plants serving local networks and reservoirs designed for multiple purposes such as irrigation, water management and electricity generation.
Wind and Solar Are Broadening the Renewable Mix
Kenya’s wind sector is led by the 310 MW Lake Turkana Wind Power project in Marsabit County. The facility uses the strong and relatively consistent winds that pass through the corridor between Mount Kulal and the surrounding terrain. It is one of the largest wind farms in Africa and required a major transmission line to connect its remote location to the national grid.
Other wind resources are found in areas such as Kajiado, Meru and the coastal region. Kenya had approximately 436 MW of installed wind capacity in 2024, and the national target calls for this to rise to about 966 MW by 2030.
Solar occupies a smaller share of grid generation but has a broader role across the country. Utility-scale facilities include the 50 MW Garissa solar plant, while commercial and industrial users increasingly install their own systems to reduce electricity costs or improve supply security. Solar is particularly important in northern and eastern areas where settlements may be distant from the main transmission network.
Kenya had approximately 443 MW of installed solar photovoltaic capacity in 2024. The 2030 target is about 807 MW, although additional behind-the-meter and captive installations may increase total use beyond capacity recorded in the central grid.
Solar home systems have also become an important part of rural electrification. Approximately 1.2 million Kenyan households had standalone photovoltaic systems by 2024. Pay-as-you-go financing, often linked to mobile payment platforms, has allowed customers to purchase basic electricity services without paying the full equipment cost at the beginning.
Mini-grids combining solar panels, battery storage and backup generation offer another option for remote communities. These systems can supply households, clinics, schools, water pumps and small businesses where an extension of the national grid would be expensive.
Renewable Electricity Is Becoming an Industrial Policy
Kenya increasingly views renewable power as more than a source of household electricity. The government and energy companies want geothermal, wind and solar resources to support manufacturing, agricultural processing, electric transport, data centres and other productive activities.
The Olkaria area illustrates this approach. The government has designated a special economic zone intended to attract industries seeking reliable renewable electricity. KenGen has also announced plans connected to a geothermal-powered fertilizer facility that would use approximately 165 MW and produce green ammonia-based fertilizer.
Direct use of geothermal heat could create additional opportunities. Steam and hot water can support greenhouse agriculture, crop drying, food processing, refrigeration and industrial heating without first being converted into electricity. Kenya’s experience in geothermal exploration and drilling is also becoming an exportable service, with Kenyan specialists participating in projects elsewhere in East Africa.
Demand growth will determine whether these investments improve the economics of the power system. New renewable plants generate more value when factories, transport systems and commercial users can consume their output. Without sufficient demand, utilities may still be required to pay generators under long-term power purchase agreements even when all available electricity is not needed.
Grid Investment Will Determine the Speed of Expansion
Kenya’s effective grid-connected generating capacity reached approximately 3,192 MW at the end of 2024. Geothermal represented 29% of that capacity, hydropower 26%, wind 14% and solar 7%. Thermal generation represented 18%, while imports, mainly from Ethiopia, accounted for another 6%.
The country’s renewable resources are often located far from its largest demand centres. Geothermal power must be transmitted from the Rift Valley, wind energy from northern regions and utility-scale solar from areas with strong irradiation and available land. Delays in transmission construction can therefore delay an entire generation project or reduce its usefulness.
Distribution losses, insufficient substation capacity, land-acquisition delays and uneven service quality also remain concerns. Total power-system losses were above 23% in mid-2024, limiting the financial benefit of additional generation.
Kenya’s renewable targets call for roughly 5,952 MW of clean generating and import capacity by 2030, including 400 MWh of battery storage. Reaching this level will require coordinated decisions about generation, transmission, storage, regional trade and consumer demand rather than simply approving more power plants.
Kenya already has one of the strongest renewable electricity foundations in Africa. Its future progress will depend on converting that advantage into reliable supply, universal access and productive economic activity. Geothermal power will remain the system’s anchor, but solar, wind, hydropower, batteries and regional interconnections will determine how effectively the country responds to rising demand.
