54L Transmission Line Rebuild: Canmore

AltaLink’s existing 54L transmission line was constructed in 1943. This transmission line has reached the end of its lifecycle. We are proposing to rebuild this line to ensure that a safe and reliable supply of power is available for years to come. 

The existing 54L transmission line is a single circuit 138 kilovolt (kV) line that is located in Canmore and Banff National Park. This proposed project involves rebuilding approximately eight kilometres of the line that runs between the Canmore Substation and the boundary of Banff National Park. Planning for the rebuild of the portion of line in the park is in early stages and not part of this project.

We will be hosting a virtual information session to answer your questions and provide more information from 6 to 7 p.m. on Wednesday, November 3. Members of our consultation, environment, electrical effects and siting teams will be available to discuss the project during the session. You can register for this event here.
