This project will consist of approximately 500 kilometres of transmission line and associated facilities in order to support increasing growth in northeastern Alberta. It will include a 500-kilovolt (kV) AC single-circuit transmission line, approximately 100 kilometres in length, running from a new substation in the Thickwood Hills area to the existing Livock 939S substation, and a 500 kV AC singlecircuit transmission line, approximately 400 kilometres in length, running from Livock 939S substation to the approved Sunnybrook 510S substation.
The proposed route, substations, and design of the transmission line are subject to approval by the Alberta Utilities Commission (AUC). Approval for the project was granted by the AUC in February 2017. The project is set to be in service in 2019.
