Our Whispering Willow North battery energy storage system (BESS) sits on the same site as our Whispering Willow North Wind Farm. We began construction of the 75-megawatt (MW) site in 2025 with a target completion of late 2026.
We’re in the permitting stage of a second phase to add another 200 MW of battery storage, which we expect to complete in 2027. When finished, the BESS facility will be our largest at 275 MW capacity.
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.
