Eastern Alberta Transmission Line

The Eastern Alberta Transmission Line is a 301-mile, 500-kV HVDC transmission line that originates at the Heathfield converter station in the Redwater-Gibbons area northeast of Edmonton and terminates at the Newell converter station in the Brooks area south of Calgary.  The transmission line cost about C$1.8bn. The project involves the development of two new converter stations capable of 240 kV and 500 kV transmission.  The project will result in increased reliability and reduce congestion in the area. Bechtel is providing project management, engineering, procurement and construction management services. The work includes approximately 1,400 steel lattice towers.    In October, 2011, the Alberta Utilities Commission (AUC), at the request of the Canadian government suspended the review process for the Eastern HVDC project pending a more thorough review of the two major north-south DC projects — Eastern Alberta HVDC and the Western Alberta HVDC project. In February 2012, a panel commissioned by Premier Alison Redford concluded that the line was needed to support the growth of the southern part of the province. Construction began in early 2013. The delay in the Regulatory process has resulted in a delay to the original construction schedules of the line. The revised in service date will be some time in 2015.
