Project overview
Hydro One is constructing a new transmission line in the County of Lambton and Municipality of Chatham-Kent. This project involves constructing a
double-circuit 230 kilovolt transmission, expanding the existing Chatham Switching Station and
Lambton Transformer Station (TS) and converting the existing Wallaceburg TS to 230 kV.
This project is part of a network of electricity infrastructure projects that will support the
regions’ economic growth. Once built, the St. Clair Transmission Line will support local food
supply, economic development and job creation. We’re completing the planning stage
now, so that we can be ready to bring additional power to the region when and where it’s needed.
