Manitoba–Minnesota Transmission Line

Manitoba–Minnesota Transmission Line

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.

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.

National Energy Board

On December 16, 2016, we filed an application with the National Energy Board requesting authorization to construct and operate an international transmission line. The application and new filings can be viewed on the National Energy Board’s website and interested individuals can review and provide comments to the federal authority.

The National Energy Board (NEB) is initiating a federal environmental assessment process for the Manitoba-Minnesota Transmission Project. The deadline for registration for Indigenous groups and members of the public is 15 August 2017. More information is available here.

Environmental Impact Statement (EIS)

The Environmental Impact Statement for the Manitoba–Minnesota Transmission Project was submitted for regulatory review in September 2015. A summary document has been developed to outline the findings of the EIS.

Project details

The Manitoba–Minnesota Transmission Project includes:

  • Construction of a 500,000-volt AC 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.
  • Upgrades to associated electrical stations at Dorsey, Riel and Glenboro.
