During 2008, due to inefficiencies a total of $220m worth of electricity was lost from transmission lines as heat. These five projects were identified as a result of that.
AESO’s plan includes two 500 kilovolts (kV) HVDC lines from the Edmonton area to the Calgary and South regions, one 500 kV double circuit AC line from the Edmonton area to the Industrial Heartland area, two 500 kV lines to Fort McMurray which includes one from the Wabamun Lake area and another from the industrial Heartland area, an additional substation and/or new transmission line in the south Calgary area, and a new transmission development in southern Alberta.
The estimated cost for the five projects is expected to be $8.1 billion as reported by Daily Commercial News and Construction Record.
