SAULT STE. MARIE, ONT. — The Ontario Energy Board has been directed by the Ministry of Energy to amend Hydro One Networks Inc.’s transmission license to develop and construct three new transmission lines to meet growing electricity demand in northeast and eastern Ontario.
The three projects will support capacity constraints and growing electricity demands in sectors including transportation, mining, steel and manufacturing.
The three projects are:
- The Mississagi to Third Line – an approximately 75 kilometre, 230-kilovolt transmission line between the Mississagi Transformer Station (west of Sudbury) and Third Line Transformer Station (Sault Ste. Marie);
- The Hanmer to Mississagi Line – an approximately 205 kilometre, 500-kilovolt transmission line between the Hanmer Transformer Station (Greater Sudbury) and the Mississagi Transformer Station (west of Sudbury); and
- The Greater Toronto Area East Line – an approximately 50-kilometre, 230-kilovolt transmission line between either the Cherrywood Transformer Station (Pickering) or Clarington Transformer Station (Oshawa) and Dobbin Transformer Station (Peterborough)
The Independent Electricity System Operator (IESO) has recommended the three new transmission lines come into service no later than 2029.
Hydro One and First Nations have been collaborating on early planning and will advance the development and construction phases of the projects together, states a release, adding First Nations have the opportunity to invest in a 50 per cent equity stake in the transmission line component of the projects once complete through Hydro One’s Equity Partnership model.
