ATCO Electric 7L65 Line Rebuild Project

ATCO Electric 7L65 Line Rebuild Project

The Alberta Utilities Commission is considering applications for new transmission lines in the Vegreville and Vermilion areas


Applications were submitted to the Alberta Utilities Commission to consider the ATCO Electric 7L65 Line Rebuild Project seeking approval 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 will be holding a hearing to review the applications and submissions from February 4-7, 2020, in Vegreville, Alberta. 

The AUC issued a notice of application for the ATCO Electric 7L65 Line Rebuild Project on January 31, 2019.

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

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