We’re building the Edgewater battery energy storage system (BESS) at the Edgewater Generating Station in Sheboygan, Wisconsin. The 99-megawatt battery project is part of our Edgewater redevelopment plan to increase reliability for the future. At maximum output, the Edgewater BESS will be able to power over 100,000 homes for four hours on a single charge. We expect it to be up and running by December 2026.
How does battery storage work?
The Edgewater battery energy storage system will charge from the grid when demand is low. It will release this energy when demand increases, such as on hot summer or cold winter days.
The ability to capture energy and release it when it's needed improves the overall efficiency of energy sources, increases system resiliency and helps support a balanced generation mix. This improved flexibility avoids customer costs that would typically be required to replace existing equipment or construct additional generation resources to meet growing energy needs.
