There are 7 major proposed transmission corridors for bringing Canadian hydropower to the Northeast U.S. Out of these 7 proposals, 3 are active (Champlain Hudson Power Express, New England Clean Energy Connect, and New England Clean Power Link). These will connect at the Canadian-U.S. border and then travel over 1,000 miles into remote areas of Eastern Canada through the Hydro-Quebec’s and Nalcor Energy’s network.

Map of proposed transmission corridors for Canadian hydroelectricity imports to the U.S.

This map from Hydro-Quebec shows its transmission lines, megadams, and generating stations.

Hydro-Quebec also connects to the Churchill Falls generating station on the Churchill (Grand) River in Labrador.

At any one time, the hydroelectricity Hydro-Quebec sends to the Northeast can be hydropower from any of its stations or even fossil fuel sources, depending on what source H-Q is deciding to use at that given moment.

As described by the consulting firm Energyzt, because H-Q is interconnected to multiple electricity markets in the U.S. and Canada, H-Q can “arbitrage between markets, buying low in one market and then reselling that energy at a higher price elsewhere.” H-Q “can buy lower cost energy where fossil fuel generators are operating, retain water in its reservoirs and then sell that water as hydropower at higher priced periods into the same or other markets….In this way, Hydro-Quebec can claim that the electricity it sells is “clean” hydropower even if it is buying fossil fuel electricity to enable those energy sales.”
