Manitoba–Minnesota Transmission Project

The proposed 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. Manitoba Hydro requires federal and provincial approval of the project. Sign up for email notifications.

We have added draft environmental protection and management plans to our document library and are asking for public feedback.

National Energy Board

On December 21, 2017, the National Energy Board issued a Notice of Public Hearing indicating they would hold a public hearing for the Manitoba–Minnesota Transmission Project and would conduct an environmental assessment pursuant to the Canadian Environmental Assessment Act, 2012.

The National Energy Board Public Hearing concluded on June 22, 2018. Information from the Public Hearing, including transcripts, is available on the National Energy Board’s website. The National Energy Board has completed and released their Reasons for Decision recommending to the Governor in Council that a certificate should be issued for the Project.

Benefits

Enhanced reliability

The project will double our ability to import electricity from the United States, helping to ensure a reliable supply of energy is available to our customers in the event of emergencies such as prolonged droughts or unforeseen equipment failures.

Import capability: Current 700MW + Additional 700MW = Potential 1400MW


Increased exports

The project will increase the amount of electricity we can sell into the United States market, at a time when new generating stations are being built in this province, helping to continue the profitable export sales that keep electricity rates lower for our Manitoba customers.

Export capability: Current 2300MW + Additional 885MW = Potential 3185MW


Lower rates

Selling surplus electricity outside of Manitoba earns revenue that helps to offset the revenue we need to collect from our customers in Manitoba. This means electricity rates in this province are much lower than they would be otherwise.

28.6% Residential, 28.6% Export, 40.4% General Service, 2.4% Other.

Project details
