Hydro One applies to build pair of new transmission lines

Hydro One Networks Inc. announced it has filed two leave-to-construct applications with the Ontario Energy Board (OEB) to seek approval to build the Northeast Power Line and the Longwood to Lakeshore Transmission Line.

The Northeast Power Line is a single-circuit 500-kilovolt (kV) transmission line between Hanmer Transformer Station (TS) in Greater Sudbury, and Mississagi TS near Wharncliffe. This critical infrastructure is expected to reinforce the transmission system’s transfer capability between northeast and northwest Ontario by approximately 900 megawatts (MW). Construction of the approximately $1.8-billion transmission line is planned to be completed in 2029.

The Longwood to Lakeshore Transmission Line is a single-circuit 500-kV transmission line between Longwood TS in the Municipality of Strathroy-Caradoc and Lakeshore TS in the Municipality of Lakeshore. The approximately $1.2-billion investment is anticipated to bring about 550 MW of electricity to the region, to support local jobs and the agri-business and manufacturing sectors in southwest Ontario. It’s expected to be completed in 2030.

“Electricity demand in Ontario is increasing. These lines are part of one of the largest transmission line infrastructure investment portfolios in Canada that we are advancing together with First Nations,” said Ryan Docherty, executive vice president, Capital Portfolio Delivery, Hydro One. “Hydro One’s success is tied to Ontario’s success. Together, we are helping build a stronger and more self-reliant economy that advances local priorities, supports good jobs and drives economic growth, while continuing to deliver value for the people of Ontario.”

Through Hydro One’s First Nation Equity Partnership Model, proximate First Nations will have the opportunity to invest in a 50 per cent equity stake in the transmission line component of each project. Together, Hydro One and the proximate First Nations will continue to collaborate on the planning, development and construction of the lines.
