AltaLink’s existing 54L transmission line was constructed in 1941 and 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 the Town of Canmore, Banff National Park and the Town of Banff. The line starts in the Town of Canmore at the Canmore Substation, continues west through the Hamlet of Harvie Heights, and into the Banff Substation in the Town of Banff. This proposed project involves rebuilding approximately 24 kilometres of existing transmission line.

In October 2021, AltaLink began consulting with stakeholders on the portion of the proposed project that runs from the Canmore Substation to the Banff National Park boundary. Since then, we have gathered valuable stakeholder feedback and completed further engineering that has supported our project planning. We have made updates to what we are proposing along portions of the line in and around the Town of Canmore.

More information about the portion of the project in Banff National Park, including how to provide your feedback, is coming soon.
