City of Edmonton Transmission Reinforcement (7078)

On September 17, 2024, the Alberta Utilities Commission (AUC) approved the AESO's City of Edmonton Transmission Reinforcement (CETR) Needs Identification Document (NID) Application.

Transmission system reinforcement is needed in the northeast area of the City of Edmonton to reliably serve the growing demand for electricity in the area. In addition, EPCOR, the transmission facility owner in Edmonton, has identified a need to replace aging infrastructure.  

The City of Edmonton Transmission Reinforcement includes the addition of a 240 kilovolt (kV) substation to replace the existing Kennedale substation. The Kennedale substation and other aging infrastructure in the area will be decommissioned. Additionally, 5 kilometres of double-circuit 240 kV line will be constructed to connect the new substation to the existing 240 kV transmission line 915L. Two new 72 kV transmission lines will also be added to connect the new substation to the existing Namao substation, which will be modified. 

While the AESO is responsible for identifying the need for transmission reinforcement and the proposed solutions to meet that need, EPCOR is responsible for substation and transmission line locations, structure types and related upgrades. Please visit EPCOR’s website at www.epcor.com/CETR for further information.
