Manitoba Hydro – Manitoba-Minnesota Transmission Project

On this page you can find:

Project Information

In its project application [Filing A81054], Manitoba Hydro is proposing to construct and operate a 500 kV alternating current international power line (IPL) extending from Manitoba Hydro’s Dorsey Converter Station in Manitoba to the international boundary between Manitoba and Minnesota (Dorsey IPL). The Dorsey IPL will connect with the Great Northern Transmission Line, a new 500 kV transmission line in the United States.

Based on the proposed design and route, the construction of the Dorsey IPL will require alterations to two of Manitoba Hydro’s existing IPLs, as well as alterations to some of Manitoba Hydro’s intra-provincial transmission lines and facilities.

The construction of the Dorsey IPL and the associated alterations to Manitoba Hydro’s existing transmission facilities is collectively known as the Manitoba-Minnesota Transmission Project (MMTP).
