Manitoba–Minnesota Transmission Project
The Manitoba–Minnesota Transmission Project (MMTP) is a 500-kV transmission line that exports reliable and renewable energy to Minnesota Power’s Great Northern Transmission Line. Learn more about our export revenues.
The transmission line runs from the Winnipeg area to the U.S. border in southeastern Manitoba. Upgrades were also made to our Dorsey, Riel, and Glenboro converter stations.
Completed on schedule and under budget in June 2020, the MMTP strengthened the reliability of Manitoba’s electricity supply and increased access to American markets. The budget as of March 2020 was estimated at $490 million.

Environmental Impact Statement
An environmental impact statement (EIS) summary document (PDF, 1.5 MB) was developed for the MMTP and outlined the concerns heard throughout the environmental assessment process and how these concerns were addressed.
The EIS was submitted to Manitoba Conservation and Climate for review in September 2015.
