The Hudson Project is a 345 kV AC powerline for the power supply of New York City from PSEG's Bergen Generating Station, in Ridgefield, New Jersey.[1][2]


It consists of a HVDC back-to-back station with a transmission rate of 660 MW and DC voltage of 180 kV at 1 Railroad Avenue (40°49′56″N 74°00′44″W / 40.83222°N 74.01222°W / 40.83222; -74.01222) in Ridgefield, New Jersey, which is connected by a 230 kV line with the nearby substation. From the static inverter plant the three-phase AC line to Consolidated Edison's W. 49th Street substation at 40°45′57″N 73°59′45″W / 40.76583°N 73.99583°W / 40.76583; -73.99583 starts, is in its whole length implemented as underground or submarine cable, buried 10 feet (3.0 m) in non-navigable and 15 feet (4.6 m) in navigable sections.[3]

After travelling through the Edgewater Tunnel, the cable enters the Hudson River at Edgewater and runs along the eastern side of the river parallel to the shore until piers 92 and 94, where it enters Manhattan.[3]

Construction of the link started in May 2011 and was completed in June 2013.[4]
