North Star Battery Energy Storage Project

North Star Storage proposes to construct the North Star Battery Energy Storage System (BESS) Project (Project) in Chisago County, Minnesota. The Project is located within the municipal boundary of the City of North Branch, adjacent to the existing North Star Solar Facility (Solar Facility), which is owned and operated by North Star Solar PV LLC, a Delaware limited liability company (North Star PV) an affiliate of North Star Storage.

North Star Storage anticipates that the Project will be sited directly adjacent to the existing Solar Facility’s collector substation and the existing infrastructure that connects the Solar Facility to the Chisago County Substation. The Chisago County Substation is the Point of Interconnection (POI) for the Solar Facility and will be the POI for the Project as well. North Star Storage anticipates that the Project will connect to the Solar Facility’s collector substation via buried 34.5 kilovolt medium voltage collection lines and, as a result, no new high voltage transmission line or generation tie line (gen-tie line) are required.  

The Project will have a nameplate capacity of up to 80 megawatts (MW) and the capability to store at least 320 megawatt hours (MWh) of energy at a given time.
