The goal of this project is to increase the energy interchange capacity between Québec and New England by building a 1,200-MW interconnection to link Québec’s power grid with new Hampshire’s.

The project involves the construction of a 300-kV direct-current transmission line, about 75 km long. This line will be extended into the U.S.A. to connect Des Cantons substation to a substation to be built in Franklin, southern new Hampshire.

The project also includes the construction of two converters at Des Cantons substation, each with a capacity of about 600 MW. They will convert alternating current to direct current, to supply the planned transmission line.
