Wisconsin Cooperative to Explore Pumped Hydro Energy Storage

Wisconsin’s Dairyland Power Cooperative is collaborating with Mine Storage International AB and Michigan Technological University to explore the potential for pumped storage hydropower in the Upper Midwest, it said on May 4.

Dairyland will be evaluating the development of underground pumped hydro at closed mines, “an opportunity that supports grid reliability and renewable energy generation while repurposing retired industrial sites in an innovative way,” it said.

Mine Storage develops abandoned mines into pumped hydro energy storage, a flexible resource similar to utility-scale battery storage. 

Michigan Technological University will serve as a technical resource as Dairyland explores potential development options. The university has led significant research and reporting on the potential of regional pumped hydro storage systems.
