The Coast Water Works Development Agency (CWWDA) is implementing a 4.6-megawatt solar power plant in Kenya's coastal region to reduce electricity costs and stabilize water supply. This project aims to lower the agency's monthly power bill, currently around Sh60 million, and alleviate financial pressures on water service providers.

Funded by the World Bank through the Water and Sanitation Development Project (WSDP) at a cost of Sh670 million, the solar installation will supply power to 11 boreholes and improve the reliability of water delivery. The project commenced in October 2025 and is expected to be completed by March 31, 2026, with 60% of Phase One already completed.

Future phases are planned to extend solar-powered pumping to Mombasa. The initiative will also enable the agency to utilize net metering, allowing excess solar energy to be fed back into the grid, ultimately reducing operational costs and enhancing sustainability.
