The Hudson project is the second major underwater transmission project completed by PowerBridge www.powerbridge.us, following the 660 Mw Neptune undersea transmission project, completed in June of 2007, which extends 65 miles between New Jersey and Long Island. Neptune has supplied approximately 20 percent of Long Island's electricity needs since going into service. The Hudson and Neptune projects provide access to power from the PJM energy grid, one of the largest and most diverse power markets in the United States.
"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," said Edward M. Stern , President and Chief Executive Officer of PowerBridge. "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 completing this complex project well ahead of schedule and therefore in time for the summer peak load period, we want to thank many different parties that helped achieve this result, especially Governor Andrew Cuomo and his staff, as well as Senator Chuck Schumer and numerous federal, state, and city agencies such as the New York State Departments of Public Service, Transportation, and Environmental Conservation, the New Jersey Department of Environmental Protection, the New York District Army Corps of Engineers, the City of New York, and the Borough of Ridgefield, New Jersey."
"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."
Using HVDC High Voltage Direct Current technology, the electricity drawn from the PJM grid is converted from AC to DC power, and then back to AC power, at a newly-built converter station in Ridgefield, NJ, for the purpose of maximizing reliability and controllability in delivering power to Manhattan.
