The Energy and Petroleum Regulatory Authority (EPRA) has called for two gas-fired power plants to be constructed urgently as a spinning reserve to balance renewable energy sources in the national grid. The spinning plants, with a proposed total capacity of 160MW, would stabilise the grid by balancing out fluctuations in wind and solar power. Hydropower currently acts as a spinning reserve, but supply is limited and vulnerable to drought, while geothermal, which serves as Kenya’s baseload, cannot be ramped up and down easily.
