Bruce-Milton 500 kV Transmission Line delivers 3,000 MW of clean energy to Ontario, integrating Bruce Power nuclear and renewables, expanding electricity transmission capacity for growing communities with Hydro One grid upgrades and environmental initiatives.

 

In This Story

A 500 kV double-circuit line enabling 3,000 MW of clean power from Bruce Power and renewables to Ontario's grid.

  • 3,000 MW added capacity, over 10 percent of provincial demand
  • Double-circuit 500 kV line from Kincardine to Milton
  • Integrates Bruce Power nuclear output and renewables
  • $700 million investment; 500 jobs, 922,000 person-hours
  • Approved by Ontario Energy Board; full EA completed

 

Hydro One recently announced the completion of its Bruce to Milton Transmission Reinforcement Project with the Energy Minister Chris Bentley and Hydro One President and CEO, Laura Formusa, tightening a bolt on the last tower of the 180 km line and finalizing its connection to Ontario's electricity grid.

 

The achievement marks the largest expansion of Ontario's electricity transmission system, including key Ontario/Michigan interconnections, in more than two decades and translates into 3,000 megawatts MW of new clean energy - enough electricity to power more than 10 percent of the province's electricity needs - from the output of two refurbished Bruce Power nuclear reactors and committed renewable energy sources.

"Today marks a major milestone in Ontario's electricity infrastructure and we are paving the way for future that offers new technologies while delivering clean, renewable power for growing communities, such as Brampton transmission facilities enhancements, and generations to come," said Minister Chris Bentley.

"We are proud to celebrate the partnerships built and strengthened as a result of the construction of this line," said Formusa. "The project was made possible through a shared commitment from the residents, businesses, municipalities, conservation groups and First Nations and Métis groups along the corridor."

The double-circuit 500 kilovolt kV transmission line extends from the Bruce Power complex in Kincardine to Hydro One's Switching Station in Milton, spanning through diverse natural areas, farm land and residential areas.

As part of the project, Hydro One developed an initiative to create and enhance natural habitat in partnership with community-based organizations, First Nations and Métis and municipalities, alongside ongoing transmission station refurbishments across the network.

The project received Ontario Energy Board approval under Section 92 Leave to Construct on September 15, 2008 and Environmental Assessment approval on December 16, 2009. Construction on the project started in 2010 and represents an investment of $700 million into Ontario's electricity system.

Construction of the Bruce to Milton line meant more than 922,000 person-hours of employment in Ontario, creating 500 jobs.
