Hydro One to Kick-start Major Transmission Projects

McGuinty Government's Green Energy Plan Creating Jobs

In a historic move to build a green energy economy, Ontario is asking Hydro One to immediately proceed with planning and implementing major transmission projects across Ontario.

The 20 transmission projects as well as investments into the distribution network are expected to create about 20,000 jobs and spur green economic development across Ontario over the next three years. The projects will unlock significant potential opportunities for greener, cleaner electricity in all parts of the province. About $2.3 Billion will be spent by Hydro One on transmission and distribution projects over the next three years.

Six core transmission network upgrades are moving forward, including North-South lines from Sudbury to Barrie and Barrie to the Greater Toronto Area and an East-West line from Nipigon to Wawa. These projects will help ensure there is enough transmission capability for renewable generation resulting from the province's Green Energy Act. Another series of core-supporting transmission projects and distribution upgrades are also moving ahead in most areas of Ontario.

In addition to bringing more renewable power online, these significant upgrades will strengthen the reliability of Ontario's transmission system, increase energy transfer across the province and beyond our borders and could one day help lead to a national east-west grid.

Hydro One may involve third party commercial entities as partners in transmission projects because of its massive scope. Aboriginal communities will be consulted and provided with opportunities to participate in the projects.
