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 the line in the park is in the early stages.

AltaLink hosted a virtual information session to answer questions and provide more information on the proposed project in November 2021. If you were unable to attend this session, you can watch a recording of it here.
