Cassils to Bowmanton Transmission Project

The Alberta Utilities Commission (AUC) approved the project in June 2011. Construction began in summer 2011 and the project was energized in November 2013.

AltaLink assembles transmission structures at designated structure yards and uses a helicopters to erect and transport structures. Using helicopters is significantly faster than other construction techniques and reduces the amount of construction traffic and corresponding environmental impacts along the transmission line right-of-way.

The Cassils to Bowmanton 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 project includes:

  • a new transmission line from west of Brooks to east of Medicine Hat
  • a new substation located west of Brooks (Cassils Substation)
  • a new substation located northeast of Medicine Hat (Bowmanton Substation)

Project Status:
complete
