Project Listing

We rebuilt portions of the 113L transmission line to ensure that a safe and reliable supply of power is available for years to come. The project involved rebuilding approximately 23 kilometres of the overhead portion of 113L line that runs from the Town of Canmore to the Kananaskis River

Reclamation activities will occur along the line throughout 2023. Depending on where you are in relation to the project, you may see or hear crews seeding the right-of-way by hand or with a hydroseeder truck. The seed mix is a blend of native species appropriate for the Bow Valley.

Vegetation debris, including branches, will be safely burned between November 22 and December 22. These vegetation burnings will be highly controlled and follow strict safety protocols. Smoke may be visible in parts of Canmore, Dead Man’s Flats and Lac Des Arcs.

AltaLink's existing 150L transmission line was constructed in 1956. We are proposing to rebuild a portion of this line to ensure that a safe and reliable supply of power is available in the area for years to come.

AltaLink's existing 164L and 616L transmission lines were both constructed more than 60 years ago and portions of both lines are located in a high-risk fire area. We are proposing to rebuild portions of these lines to ensure that a safe and reliable supply of power is available for years to come.

AltaLink's existing 185L and 412L transmission lines were constructed more than 60 years ago and portions of both lines are in a high-risk fire area. Part of our wildfire mitigation plan includes strengthening our system and making proactive safety improvements so that it is less likely to contribute to igniting wildfires. We’ve identified theses lines as a high priority and are proposing to rebuild portions of the lines to raise the safety and design performance to current standards.

The proposed project is located approximately one kilometre north of the Town of Pincher Creek. It involves rebuilding approximately 5.5 kilometres of:
• the existing 69 kilovolt (kV) single circuit transmission line (called 185L)
• the existing 138 kV single circuit transmission line (called 412L)

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.
