St Joseph 115-kV Transmission Line and Substation upgrade - Great River Energy

St Joseph 115-kV Transmission Line and Substation upgrade

Great River Energy, wholesale electric supplier to Stearns Electric Association, is proposing to construct 3.2 miles of115-kV (115,000 volt) transmission line overtaking and replacing an existing 69-kV transmission line. Two substations along the route will require modifications and additional electrical apparatus to accept the higher voltage.

Over the last decade, Great River Energy has been upgrading the St. Joseph area to a more reliable 115-kV transmission system. This project will complete the area upgrade and loop the 115-kV system.

Permitting / environmental approvals

Great River Energy submitted a route permit application to the Minnesota Public Utilities Commission (PUC). After application, PUC and Department of Commerce, Energy Environmental Review and Analysis (DOC EERA) staff will facilitate public meetings and provide other opportunities for input from the public and regulatory agencies. The DOC EERA will prepare an environmental assessment for the project. Construction cannot begin until an approved route permit is granted by the PUC.

New or amended easements may be requested to provide adequate rights. Landowners along the proposed transmission line will be contacted to review the project and information will also be shared on tree removal, construction access and restoration of the right of way.
