WINDSOR, ONT. — The Ontario government is accelerating the development of five new electricity transmission infrastructure projects to power the new Stellantis–LGES battery plant and the growing greenhouse sector in southwest Ontario.
The government has issued an Order-in-Council declaring three transmission line projects as priorities, streamlining the Ontario Energy Board’s (OEB) regulatory approval process for the lines, indicates a release.
The priority declaration requires the OEB to accept that the three initial lines are needed when assessing whether the projects are in the public interest, expediting the review process so projects can be brought online earlier.
The OEB has also been directed by the minister of energy to amend the transmission license of Hydro One, requiring it to undertake development work and seek approvals for four of the identified transmission lines.
The transmission projects between London, Windsor and Sarnia represent an investment of more than $1 billion and are proposed to be developed in phases through 2030.
- The Chatham to Lakeshore Line, a 230-kilovolt line from Chatham Switching Station to the new Lakeshore Transformer Station currently under construction in the municipality of Lakeshore.
- The St. Clair Line, a 230-kilovolt line from Lambton Transformer Station, south of Sarnia, to Chatham Switching Station.
- The Longwood to Lakeshore Line, a 500-kilovolt line from Longwood Transformer Station, west of London, to the new Lakeshore Transformer Station.
- A second 500-kilovolt line from Longwood Transformer Station to Lakeshore Transformer Station, with scope to be further refined through planning by the IESO.
A 230-kilovolt line that would run from the Windsor area to Lakeshore Transformer station, with scope to be further refined through planning by the IESO.
