We’re building the Wever battery energy storage system (BESS) at the site of the Wever solar project. In addition to the 150 megawatts (MW) the solar panels generate, the storage system will hold 99 MW. The storage system will be able to power the equivalent of over 73,000 homes for four hours. We expect the Wever BESS to be operational by December 2025.
How does battery storage work?
Battery storage systems charge from the grid when energy demand is low or directly from solar projects when excess renewable energy is abundant. They discharge energy when demand increases, such as on hot summer or cold winter days.
The ability to capture and store energy to use as needed improves the overall benefit of renewable resources. This flexibility helps us avoid the need to replace existing equipment or construct additional generation resources to meet growing demand.
