Chapel Rock to Pincher Creek Area Transmission Development

The Chapel Rock to Pincher Creek Area Transmission Development includes:

  • A new substation, named Chapel Rock, which will connect to the Alberta/British Columbia intertie transmission line located west of Highway 22.
  • A new transmission line connecting the Chapel Rock Substation to either the existing Goose Lake or Castle Rock Ridge substations, both located north of Pincher Creek.

The location of the new substation and potential routes for the new transmission line have not been determined.

AltaLink online community workshop
If you were unable to attend our community workshops on April 10 and 11, you can also participate through our online workshop, which will be available until April 30 at

The input gathered will be used in our routing selection process. 

We will share more information about routing options and structure types in late spring and ask for your input again at that time.
