Delivering Clean Energy to Minnesota

Minnesota Power completed construction on the Great Northern Transmission Line which will bring clean, emission-free energy into Minnesota, meet growing energy demands and increase system reliability. The Great Northern Transmission Line, which will deliver hydropower generated by Manitoba Hydro to customers in the United States, consists of a 500 kV transmission line from the Minnesota-Manitoba border to the Iron Range 500 kV Substation near Grand Rapids, Minnesota, as well as associated substation facilities and transmission system modifications.

Several priorities drove the need for the Great Northern Transmission Line including:

  • Access to clean, affordable, reliable energy for Minnesota Power customers and the region
