Landscape in the study area

The project consists of building a transmission line extending approximately 100 km between Appalaches substation in Saint-Adrien-d’Irlande (near Thetford Mines in the Chaudière-Appalaches region) and a connection point on the Québec–Maine border.

The new 320-kV direct-current line will connect to the future New England Clean Energy Connect (NECEC) line, slated for construction in Maine.

In tandem with this project, a new AC-to-DC converter will be installed at Appalaches substation to supply the planned transmission line.

Commissioning is scheduled for 2022.
