Overview

The Alberta Electric System Operator applied for approval of the need for transmission development in northeast Edmonton to serve load growth and replace aging transmission assets in the area. The AUC approved the application on September 17, 2024, in Decision 28633-D01-2024.

The proposed transmission development would include the following major components:

• Add a new 240-kilovolt (kV) substation, to be designated the Fort Road Substation, including two 240/72-kV transformers, two 240/15-kV transformers, and associated 240‑kV and 72-kV circuit breakers.
• Connect the proposed Fort Road Substation to the existing 240-kV Transmission Line 915L using an in-and-out configuration.
• Add two 72-kV circuits to connect Fort Road Substation and Namao Substation.
• Modify the Namao Substation, including adding associated 72-kV circuit breakers.
• Discontinue from use for transmission purposes the Kennedale Substation and the four 72-kV transmission lines 72CK12, 72CK13, 72NK23 and 72CN10.

The map below indicates the general area where the transmission development is proposed. However, the exact routes and sites for the proposed transmission facilities are not determined and may extend beyond the areas shown. A second application, from the transmission facility owner in the area, will be required to determine the exact location of facilities.

Further information about the proceeding is available through the AUC’s eFiling System under Proceeding 28633.
