The Alberta Utilities Commission is currently considering applications from EPCOR Distribution & Transmission Inc. for the Strathcona Area Transmission Upgrade to build a new transmission line east of Gateway Boulevard near the Whitemud Freeway and upgrade the Dome substation in Edmonton.
The Alberta Electric System Operator has indicated in its needs identification document that the project is needed to serve growth in the area. The Alberta Utilities Commission is considering the need for the upgrade the Dome 665S Substation and the Strathcona Substation Enhancement project which includes a new 72-kilovolt (kV) transmission line.
The AUC issued a notice of application for the Strathcona Substation capacity increase and transmission line on July 17, 2018.
EPCOR Distribution & Transmission Inc. has applied to construct a new four to five kilometre 72-kV overhead and partial underground transmission line, discontinue the use of existing 72-kV transmission line 72RS5 located along 103 Street and alter the Dome 665S Substation by expanding the fenceline near Parsons Road. The new transmission line 72DS26 would connect the Dome 665S to the Strathcona Substation which would either follow primarily along 99 Street or 97 Street with several route variants considered as potential options for approval.
The new line would need to go underground to cross three existing 240-kV transmission lines south of 31 Avenue on Parsons Road that are owned by AltaLink Management Ltd. EPCOR Distribution & Transmission Inc. applied to construct a new fibre optic line, designated as FO-158, on the same structures and same route as the new transmission line 72DS26. The proposed routes are entirely located within the city of Edmonton’s road allowance and no new rights-of-way are expected to be required.
