The Saunders Lake Substation and Transmission Lines project is part of the South and West of Edmonton Area Transmission Development. The area south and west of Edmonton has grown significantly in recent years and the demand for electricity has increased. Transmission system reinforcements are required to make sure residents continue to have a reliable supply of electricity for years to come.
The proposed Saunders Lake Substation and Transmission Line project will be located to the east of Leduc and south of Edmonton near Nisku.
The project includes:
- a new substation (to be called Saunders Lake 289S)
- building two new 240 kilovolt (kV) transmission lines to connect the Saunders Lake Substation to the existing 910L/914L transmission line
- building two new 138 kV transmission lines to connect the Saunders Lake Substation to existing lines in the area (called 174L and 858L) and the existing Nisku 149S Substation
- salvaging portions of the 780L and 858L lines
- modifications to the Nisku Substation
Please note: on page 4 of the Volume 3 newsletter under "Minor Route Adjustments" it was incorrectly stated that: Leduc County has begun acquiring land for future road expansion from the intersection of 9th Avenue and Township Road 502 heading east. This should have read 9th Street and Township Road 502.
