Company proposing utility-scale battery energy storage system in Renville County
OLIVIA — A San Francisco, California-based renewable energy company is eyeing a site in Renville County for what would be Minnesota’s largest battery energy storage system.
Mission Clean Energy intends to build a utility-scale, 200-megawatt battery storage system in Camp Township, near the community of Franklin in the county’s southeast corner. The proposed location would allow the storage site to connect to Great River Energy Cooperative’s Cedar Mountain substation on a high voltage transmission line.
The battery storage system would take energy from the transmission grid and discharge it back onto the grid in times of need. It would prevent blackouts and improve the resiliency of the transmission grid, Carly Grossman, development manager with Mission Clean Energy, told the Renville County Board of Commissioners at their meeting on Jan. 16.
Renville County would receive the benefits of property taxes from the project — as well as the economic activity associated with its construction.
The project is still in the very early stages. Mission Clean Energy is hoping it can connect to the grid in 2028, but has yet start to the process of obtaining authorization from the Midwest Independent System Operators (MISO). The process will require engineering studies and a minimum of a one-year time frame, according to Grossman.
