We’re building the Lansing battery energy storage system (BESS) at the site of the former Lansing, Iowa coal facility. The battery storage system can store up to 150 megawatts of power – enough energy to power over 150,000 homes for up to four hours. We expect it will be up and running by December 2026.
How does battery storage work?
Battery storage systems typically charge from the grid when demand is low or directly from renewable resources, usually solar, when generation is abundant. They then release this energy when demand increases, such as on hot summer or cold winter days.
The ability to capture energy for use as needed improves the overall efficiency of energy sources. It gives us the flexibility to use more energy from renewable resources. It also helps avoid expenses to build more generation to meet growing energy needs.
