Presidential Permit Paves Way for Minnesota Power’s Great Northern Transmission Line

Will clear the way for an international transmission line between MN and Manitoba

Minnesota Power’s Great Northern Transmission Line received federal approval today when the U.S. Department of Energy issued a Presidential Permit.

This permit will clear the way for building the international transmission line to deliver clean energy from Canada’s extensive hydropower resources to Minnesota, while also strengthening reliability of the power grid.

The Presidential Permit is the final major regulatory approval needed before construction can begin. The permit is required, as the transmission line will cross the international border between Manitoba and Minnesota, connecting Manitoba’s Hydro’s Manitoba and Minnesota Transmission Project.

Construction is expected to begin early next year on the 500-kilovolt line that will deliver 383 megawatts of renewable hydropower purchase from Manitoba Hydro to Minnesota Power’s customers beginning in 2020.

Minnesota Power estimates the total cost of the project to be between $560 million and $710 million, with the company’s portion of the cost estimated between $300-350 million.
