In addition to fast response generators, energy storage systems can be exploited to provide frequency regulation service due to their fast ramping characteristic. Delivered on time, the Bokhol site is already connected to Senelec's grid our energy delivery, Walo Storage marks a major. . The Walo Storage facility, commissioned on July 14th, represents West Africa's first solar power plant integrated with battery storage specifically for grid frequency regulation. A key feature of the Walo Storage facility is its ability to provide critical stability and backup power during outages. . Dakar, Senegal, August 7, 2025 – Just one year after laying the foundation stone, Africa REN announces the commercial commissioning of Walo Storage, the first photovoltaic facility in West Africa combined with lithium-ion battery storage, designed for frequency regulation and to meet local energy. . Frequency control aims to maintain the nominal frequency of the power system through compensating the generation-load mismatch.
