The Canada Energy Regulator has authorized a 58 km Hertel–New York interconnection line, which will link to the Champlain Hudson Power Express (CHPE) line, under construction in New York since December 2022.
The project will consist of a transmission line between Hertel substation in La Prairie and an interconnection point in the Riviere Richelieu at the Canada–U.S. border linking the CHPE line.
The commissioning of these installations is scheduled for May 2026. The two lines will supply clean hydroelectricity generated by Hydro-Quebec to New York City with a capacity of 1,250 MW and reduce the city’s carbon emissions by approximately 3.9 million metric tonnes per year, equivalent to eliminating 44 percent of the cars circulating in New York City.
The Hertel–New York line, crossing an international border, was evaluated by the Commission of the Canada Energy Regulator. The announcement was followed by a 16-month environmental assessment process, sustained collaboration between Hydro-Québec and the communities affected by the project.
