ATCO Electric 7L65 Line Rebuild Project

The AUC has approved applications for new transmission lines in the Vegreville and Vermilion areas


The Alberta Utilities Commission has approved applications for the ATCO Electric 7L65 Line Rebuild Project to rebuild the existing Transmission Line 7L65 to allow the facility to operate at full thermal capacity. The transmission is located between the existing Vegreville 709S Substation and the existing Vermilion 710S Substation. The AUC issued Decision 24102-D01-2020 on April 23, 2020.

The AUC held a hearing to review the applications and submissions from February 4-7, 2020, in Vegreville, Alberta. A notice of application for the ATCO Electric 7L65 Line Rebuild Project was originally issued on January 31, 2019.

ATCO Electric Ltd. receives approval to construct a new single-circuit 144-kilovolt (kV) transmission line to replace the existing 93-kilometre Transmission Line 7L65 which will consist of an approximately 22-kilometre segment (designated as Transmission Line 7L134) between the Vegreville 709S Substation and the approved Vincent 2019S Substation, and an approximately 77-kilometre segment (designated as new Transmission Line 7L65) between the Vincent 2019S Substation and the Vermilion 710S Substation.

ATCO Electric Ltd. is also approved to alter Transmission Line 7LA65 by moving the tap location on Transmission Line 7L65 to a point on the new Transmission Line 7L65, and to alter the existing 144-kV Transmission Line 7L129. The alteration of Transmission Line 7L129 will involve rebuilding approximately 800 metres of this line on double-circuit structures with new the Transmission Line 7L65. The double-circuit transmission line segment will be located in the northeast quarter of Section 36, Township 50, Range 7, west of the Fourth Meridian.
