Project will carry electricity from Canada to NYC

On Aug. 9, ships will begin burying a power line from Canada that will run 68 miles under the Hudson River between Greene and Rockland counties, representatives for the project said on Monday (July 29). 

The $6 billion, 339-mile Champlain Hudson Power Express, whose construction began in November 2022, will pass by Dutchess, Putnam and seven other counties to its destination in Astoria.

Two 5-inch cables with a capacity of 400 kilovolts will be buried 7 feet below the riverbed during most of the route, according to a construction and environmental-management plan filed with the state Department of Public Service.

The completed line, which begins at a converter station in Quebec and spans 339 miles, is supposed to supply 1,250 megawatts of renewable electricity from a hydropower facility to ConEd, enough to power more than 1 million homes when it goes online in spring 2026 and reduce carbon emissions statewide by 37 million metric tons.
