The Hudson Project

project img 1

The Hudson Transmission project is a 660 MW electric transmission link between New York City and PJM Interconnection. While its main purpose is to provide a new source of electric power for the New York City customers of the New York Power Authority (“NYPA”), implementation of the Project also included very significant upgrades and reinforcements to the transmission system in New Jersey. Construction of the project began in May 2011 and was completed in June 2013.

The Hudson cable is entirely underground and underwater, using high voltage direct current (“HVDC”) technology. The route begins in Ridgefield, New Jersey, the site of the Hudson converter station, where it interconnects with the PJM system at a PSE&G substation. The line follows existing railroad rights-of-way, through an inactive railroad tunnel to the edge of the Hudson River in Edgewater. It is then buried beneath the Hudson for approximately three-and-a-half miles to a landfall point near Pier 92 in Manhattan. The final stretch of cable is routed beneath the West Side Highway and ultimately into the ConEdison W. 49th Street Substation.

The Project was developed by Hudson Transmission Partners, LLC (“HTP”), whose principals were also responsible for the successful development, construction, and operation of the Neptune Regional Transmission System (“Neptune RTS”), another undersea transmission link running 65 miles between PJM and Long Island. PowerBridge, LLC of Fairfield, Connecticut is the parent company for Hudson, Neptune, and West Point Transmission, a major transmission infrastructure project now in development.

More About Neptune...

Neptune was completed in June 2007, on budget and ahead of schedule, by the same PowerBridge team responsible for the Hudson Project, and which continues to oversee their operation. Since commencing operation, the Neptune system has exceeded expectations in terms of availability and the amount of power brought onto Long Island. The project includes two converter stations, an undersea cable buried underneath the Raritan River and the Atlantic Ocean, and a land-based underground cable that extends up the shoulder of the Wantagh Parkway on Long Island. Technology, equipment, and installation methodologies used for Neptune are similar to those used for the Hudson Transmission Project.

The Neptune RTS cable runs approximately 65 miles between Sayreville, New Jersey and New Cassel (North Hempstead) on Long Island, and serves the Long Island Power Authority (“LIPA”) with enough power for 600,000 homes.
