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.

As part of today’s announcement, the government has directed the NEB to amend five project conditions in order to respond to and accommodate concerns raised by Indigenous groups during the Crown consultation process.  The modification of NEB conditions is responsive to the guidance provided by the Federal Court of Appeal decision on the Trans Mountain Expansion project.

The government also responded to three suggestions made by the NEB in its Reasons for Decision Report, including through the creation of a terrestrial and cultural studies initiative to support Indigenous-led studies on issues related to the project.

Approving good projects following thorough reviews is part of the government’s plan to create good, middle class jobs, protect the environment, and advance reconciliation with Indigenous peoples.

The Great Northern Transmission Line is to be constructed by Minnesota Power. It will terminate at Iron Range Station located northwest of Duluth, Minnesota. Subject to regulatory approvals, the projected in service date is mid-2020. The budget as of the spring of 2017 is estimated at $453 million.

Right-of-way and tower design

The right-of-way required for the transmission line will depend on the design of the tower structures. Predominantly 2 tower types will be utilized and will typically range in height from 40 to 60 metres. Spacing between towers will 400 to 500 metres apart on average.

Station modifications

For the transmission line to be compatible with the existing system, modifications to both Riel and Dorsey converter stations will be undertaken.

Although distant from the proposed transmission line, modifications to Glenboro Station will also be required, including extending the current switch yard and installing additional equipment. Several towers on existing lines will be relocated to accommodate the station expansion.
