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 rebuilding portions of the lines to raise the safety and design performance to current standards.
The approved 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)
Instead of rebuilding these as two separate lines, AltaLink will consolidate both of the single-circuit lines into one new double-circuit transmission line. The new transmission line will be rebuilt within AltaLink’s existing rights-of-way.
