The Cedar Rapids battery energy storage system (BESS) sits adjacent to our Deer Run substation. Online since 2022, the 5-megawatt system can store enough electricity to power approximately 5,000 homes for two hours. When launched, the Cedar Rapids BESS was our largest project. It helped grow our renewable energy portfolio and pave the way for larger BESS facilities in Iowa and Wisconsin.
How does battery storage work?
Battery storage systems charge from the grid when energy demand is low or directly from wind or 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 when needed improves the overall benefit of renewable resources.
