Canada, Ontario: Hydro One has begun construction on the St. Clair transmission line, a major infrastructure project in southwestern Ontario valued at $340.8 M (C$471.9 M).
The project includes a 64 km double-circuit 23 kV line linking Lambton County with Chatham-Kent. It also involves expanding the Chatham switching station and Lambton transformer station, and upgrading Wallaceburg transformer station to 230 kV by 2028.
Once complete, the line will deliver an additional 450 MW of clean energy to the region, enough to power a city the size of London, Ontario. The investment is expected to boost the electricity grid’s reliability and support rising demand driven by electric vehicle manufacturing and agricultural operations.
Hydro One chief operating officer Megan Telford said the project is about more than infrastructure, calling it a step towards powering Ontario’s future. She emphasised the role of partnerships with First Nations, and the importance of sourcing goods and services from Indigenous and Ontario suppliers.
The construction phase is projected to create around 70 jobs, with Canadian contractors Forbes Bros. Group of Companies and Black & McDonald leading the build.
Launched in 2022 after public and Indigenous consultations, the initiative is part of Ontario’s Energy for Generations plan to ensure reliable and affordable electricity. It also forms part of a broader network of projects, including the recently completed Chatham to Lakeshore line and the ongoing Longwood to Lakeshore project.
