Manitoba–Minnesota Transmission Project

The Manitoba–Minnesota Transmission Project will strengthen the overall reliability of Manitoba’s electricity supply, allow Manitoba Hydro to fulfill current export sales agreements, and increase access to markets in the United States, supporting the export sales that keep rates lower for Manitobans.

We have received both federal and provincial regulatory approval to move forward with the 500-kV transmission line from the Winnipeg area to the U.S. border in southeastern Manitoba where it will connect to the Great Northern Transmission Line to be constructed by Minnesota Power. This will include upgrades to the Dorsey, Riel, and Glenboro converter stations.
