Chapel Rock to Pincher Creek Area Transmission Development

The Chapel Rock to Pincher Creek Area Transmission Development includes:

  • A new 240 kV transmission line, between 35 and 47 km long, connecting a new proposed substation to be called the Chapel Rock Substation, to either the existing Goose Lake Substation or Castle Rock Ridge Substation, both located north of Pincher Creek. 
  • The new proposed Chapel Rock Substation will connect the new transmission line with the existing 1201L transmission line, which is the Alberta/British Columbia intertie. 
  • To connect the Chapel Rock Substation and 1201L transmission line, some modifications to the existing 500 kV structures or a new 500 kV line up to 13 km long may be required.

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