The Cooking Lake 138 kV Transmission Line and Substation Upgrade project is part of the South and West of Edmonton Area Transmission Development. This area has grown significantly in recent years and the demand for electricity has increased. Transmission system reinforcements are required to make sure residents, businesses and industry continue to have a reliable supply of electricity for years to come.
The proposed project includes:
- building approximately 25 km (15 miles) of double circuit 138 kV transmission line from the existing 780L line to the Cooking Lake 522S Substation
- potentially modifying a portion of the 780L line and the 174L line to connect to the new double circuit line
- modifications to and expansion of the fence line at the Cooking Lake 522S Substation
