The Bruce to Milton Transmission Line project officially opened Tuesday, June 19, 2012. Hydro One completed the new line, the first new line to be completed since the late 1970′s, six months ahead of schedule. Over 700 new transmission towers, connecting over 180 kilometres of transmission wire, were constructed over the course of the project.
The project ranked 45th on ReNew Canada’s annual Top 100 Projects list and will allow an additional 3,000 megawatts of power to flow onto the electrical grid in Ontario. Most of this power will come from two nuclear reactors that are currently being refurbished at the Bruce Power nuclear facility.
However, the project will also facilitate the integration of more than a dozen wind and solar projects that have been approved by the province but were unable to be connected to the transmission grid until now. There has also been some concern that this will lead to an even larger power surplus in Ontario. But, the looming shut down of nuclear reactors at the Darlington nuclear facility for refurbishment, coupled with the projected closing of the Pickering Nuclear station in 2020, means that Ontario needs to build new transmission assets now in order to avert future energy shortages and ensure an adequate supply of electricity stays on the grid.
