To be developed in Northwestern Ontario, the East-West Tie Line will be about 400km long and run between Thunder Bay and Wawa.
The line is planned to enhance the reliability of electricity supply in Northwestern Ontario by increasing the amount of electricity that can be transfered between the transmission system in the Northwest and the rest of Ontario.
Upper Canada Transmission is a partnership of NextEra Energy Canada, Enbridge and Borealis Infrastructure Management.
Ontario Energy Board said the Ministry of Energy identified the East-West Tie Line as a priority project in its Long Term Energy Plan.
The board also said Upper Canada Transmission has the authority to spend about $22.2m on the development work and to recover the costs.
