Description:

A 180 km, double-circuit, 500 kV transmission line is being built on a widened existing corridor between the Bruce Power Facility in Kincardine and Hydro One’s switching station in Milton. This project represents the largest expansion to Ontario’s transmission system since the late 1970s. In July of 2011 construction reached the halfway point. The project will allow an additional 3,000 MW of power to flow onto the Ontario power grid. This project represents the first time that Hydro One has used a third-party contractor, Valard, to complete a transmission project.
