Riverview Substation Project

Riverview Substation Project

The Alberta Utilities Commission is currently considering an application for a new substation and connection lines in Edmonton


The Alberta Utilities Commission is currently considering applications from EPCOR Distribution & Transmission Inc. and AltaLink Management Ltd. for the Riverview Substation Project to construct a new substation and several transmission connection lines in the south west of Edmonton.

The Alberta Electric System Operator has indicated in its needs identification document that the project is needed to serve growing electricity demand in the area.

The AUC issued a notice of application for the Riverview Substation Project on February 2, 2018. 

EPCOR Distribution & Transmission Inc. has applied to construct a new substation, designated as the Riverview Substation that would connect to transmission line 1139L via two EPCOR Distribution & Transmission Inc.-owned 70-metre slack-span connections. The substation would contain two 240/25-kilovolt (kV) transformers, four 240-kV circuit breakers, and fourteen 25-kV circuit breakers. EPCOR Distribution & Transmission Inc. also proposed to construct two fibre optic connection lines.

AltaLink Management Ltd. has applied to alter transmission line 1139L to support EPCOR Distribution & Transmission Inc.'s slack-span connections from the Riverview Substation. The existing transmission line 1139L would be split into two sections, with one designated as transmission line 1139L and the other as transmission line 1164L.
