In order to implement a 40 MW/160 MWh battery energy storage system (BESS) project, Senegal's national electricity utility, Senelec, signed a 20-year capacity change agreement (CCA) with developer Infinity Power.

The BESS project will be built at the Tobène substation in Thiès and operated in tandem with Infinity Power's 158.7 MW wind farm, the Taiba N Wind Farm. Diaye (PETN). It will have a nominal power of 40 MW and an energy storage capacity of 160 MWh and will last for four hours. Construction of the BESS will begin in early 2024 and should be completed and operational in 2025. It will be one of the largest projects of its kind in West Africa. It will provide ancillary services such as frequency regulation, reactive power, and energy charge and discharge.
