South Foothills Transmission Project

AltaLink submitted a Facilities Application for this project to the Alberta Utilities Commission (AUC) for review in September 2012. To view the application please visit https://www.auc.ab.ca/eub/dds/iar_query/ViewApplication.aspx?appnumber=1608861.

The AUC approved the project for construction on October 7, 2013. While the AUC has approved AltaLink's preferred route on the east side of Claresholm, the AUC directed AltaLink to gather additional information on a route on the west side of Claresholm, suggested by a stakeholder group known as the Committee for East Route Conservation (CERC). The AUC has directed AltaLink to investigate the route and we submitted a report on the suggested route to the AUC in December 2013. On February 25, 2014, the AUC issued a response to AltaLink's report. In the response the AUC stated that it accepts AltaLink's conclusion that the preferred route on the east side of Claresholm has lower overall impacts than the CERC route on the west side of Claresholm. AltaLink is no longer required to pursue the CERC route and may begin construction on the approved east route.

Thank you for participating in our consultation process – your input is important to us.

The South Foothills Transmission Project is part of an area transmission development called the Southern Alberta Transmission Reinforcement (SATR). This reinforcement includes new transmission lines and upgrades to the electric system in southern Alberta. These projects will connect new wind-generated power to Alberta's electric system and strengthen the transmission system in the area.


The approved project includes:

  • a new double circuit 240 kV steel lattice transmission line approximately 123 kilometres in length from south of Fort Macleod to east of High River
  • a new substation south of Fort Macleod, to be called Windy Flats
  • a new series capacitor station (similar in appearance to a substation) to be located approximately in the middle of the transmission line

*The existing 911L transmission line will be removed once the new line is in service. The removal of the existing 911L line will be included in a separate project.

Project Status:
