The power delivered into the New England "power pool" via The Northern Pass transmission line will come from Hydro-Québec, the world's largest producer of hydroelectric energy.
The Hydro-Québec system includes 60 hydroelectric- generating stations, as well as a wind farm, 26 reservoirs, and more than 570 dams and control structures. About 98 percent of Hydro-Québec’s power is generated by hydroelectric facilities. The remaining two percent is generated by a mix of wind, thermal, and nuclear power facilities.
Hydro-Québec does not need to build any new generation to support The Northern Pass project. It already has the production capacity to make use of the new transmission line.
