Hydro One has filed an application with the Ontario Energy Board (OEB) to upgrade an existing transmission line and operate it at a higher voltage as part of its Etobicoke Greenway Project.
The investment of more than $73 million is intended to help meet the growing energy demand of homes, businesses and public transit initiatives by bringing an additional 300 MW of clean power to the region – enough to power a city the size of Burlington. The expansion is also expected to create a new community green space along the 6.5-kilometre corridor that connects the Richview and Manby transformer stations in Etobicoke.
