Kenya has accomplished notable advancements in the expansion of renewable energy-based electricity and the enhancement of electricity access, thereby establishing itself as a leader in clean energy across the African continent, according to a report from the International Energy Agency (IEA).
Kenya stands out as a frontrunner in enhancing electricity accessibility within East African nations, raising the percentage from 37 percent in 2013 to 79 percent by 2025. Concurrently, the nation has effectively utilized its plentiful renewable resources, with almost 90 percent of its electricity production now derived from clean energy sources.
The installed power generation capacity in Kenya exceeds 3.5 gigawatts (GW), predominantly from renewable sources. By 2025, geothermal energy constituted 26 percent of the capacity, with hydro at 24 percent, solar at 12 percent, and wind also at 12 percent, while thermal sources contributed the remaining 26 percent. In the last ten years, the incorporation of approximately 750 megawatts (MW) of geothermal capacity, in conjunction with the expansion of solar and wind energy, has strengthened the nation's hydropower foundation and diversified its energy portfolio.
In spite of these successes, the rising share of variable renewable energy (VRE), mainly derived from solar and wind, has created new challenges regarding grid stability, reliability, and resilience. The inherent variability of these sources means that their output changes based on weather conditions, which adds complexity to power system operations.
The IEA delineates VRE integration into six phases, each indicating the extent of impact on the power system. Presently, Kenya finds itself in Phase 3, where renewable energy begins to exert a considerable influence on system operations. At this point, the priority shifts from just augmenting capacity to ensuring the system's stability, reliability, and affordability. In 2024, VRE represented about 19 percent of Kenya's total electricity generation, with roughly 4 percent derived from solar PV and 14 percent from wind.
The report underscores that the expansion of renewable capacity by itself will not adequately address future energy requirements. Kenya is required to reform its market design, regulatory structures, and operational practices.This involves refining forecasting systems, fortifying grid management, and augmenting the power system's adaptability to rapid supply changes.
The initial pillar is open access, which entails permitting a greater number of participants, including private entities, to utilize transmission and distribution networks. This approach can enhance competition, draw in investments, and boost efficiency within the power sector.
The second pillar encompasses flexibility and storage, both of which are crucial for managing fluctuations in renewable energy generation. Technologies like battery storage, flexible generation, and demand response systems can contribute to grid stabilization.
The third pillar focuses on the establishment of additional services, like frequency control and reserve capacity, which maintain the system's security even when there are changes in renewable output.
Ultimately, Kenya's subsequent phase of energy development will be contingent upon not merely augmenting capacity, but also on constructing a power system that is more resilient and adaptable.
