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.

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.
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.
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.
What is transmission? How does it fit into our system?
Watch to learn where our electricity comes from and how it gets to the places we use it.
The value of electricity exports
Watch our video to learn more about transmission connections and the value of exports to our customers.
The value of reliability
Watch our video to learn more about transmission connections and the value they provide our customers by enhancing reliability.
Why does Manitoba need new transmission?
Watch to learn how the demand for electricity has increased and how we need to change our system to accommodate the growing need.
How do we develop transmission lines?
Watch to learn how we work with communities to minimize the effects of transmission lines on people and the environment.
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.
Manitoba Clean Environment Commission
As part of the regulatory review process, the Clean Environment Commission is now reviewing the Manitoba-Minnesota Transmission Project. For more information, view the Clean Environment Commission website.
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.

What will the Manitoba-Minnesota Transmission Project look like?
This simulation illustrates what the project may look like on the landscape.
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.
