Hudson Transmission Project Goes Live
LCG, June 4, 2013--PowerBridge, LLC announced yesterday that its affiliate, Hudson Transmission Partners, LLC ("HTP"), has completed the underground and underwater electric transmission project between Ridgefield, New Jersey and Manhattan, and the project has now commenced power delivery to Manhattan. Construction on the project commenced in May 2011.
The Hudson Transmission Project employs an HVDC (High Voltage Direct Current) technology to provide up to 660 MW of power via a 345-kV AC cable from the PJM grid into Manhattan. A back-to-back AC-DC-AC converter station was constructed at 1 Railroad Avenue in Ridgefield, New Jersey to control very precisely and reliably to serve Manhattan.
The transmission cable extends from the PSE&G Bergen substation in Ridgefield to the nearby HVDC converter station, and it then runs approximately 3.5 miles underground to Edgewater, New Jersey, where it enters the Hudson River and is buried a minimum of 10 feet below the bottom of the river. The cable proceeds southward down the river on the New York side for about three miles before turning toward a landfall point, terminating at the Con Edison West 49th Street substation.
The estimated project cost is approximately $850 million.
In addition to the Hudson Transmission Project, PowerBridge completed the 660 MW Neptune undersea transmission project in June 2007. The Neptune Project extends 65 miles between New Jersey and Long Island.
The President and Chief Executive Officer of PowerBridge stated, "Like Neptune, the Hudson project shows how this type of technology can bring reliable electric power to densely populated areas in a cost-effective, non-controversial, and environmentally friendly way. It is also a great example of public and private interests working successfully in partnership to expand and modernize the nation's electric system.... In addition, we particularly want to acknowledge the extraordinary teamwork and cooperation of our customer the New York Power Authority, our principal contractors Siemens and Prysmian, Con Edison, the regional transmission organizations PJM and NYISO, New Jersey utilities PSE&G and First Energy, our investors and lenders, and the many talented workers who helped design, build, and install the project."
