The proposed Chapel Rock to Pincher Creek Area Transmission Development includes:

  • A new 240 kV transmission line 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.
