Chapel Rock to Pincher Creek Area Transmission Development

System Capacity: The maximum power capability of a system. For example, a utility system might have a rated capacity of 5000 megawatts, or might sell 50 megawatts of capacity.
Equipment Capacity: The maximum power capability of piece of equipment. For example, a generating unit might have a rated capacity of 50 megawatts.

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.
