Siemens AG has been awarded a $200 million contract to manufacture an underwater link to supply power from New Jersey to Long Island.

Project developer Neptune Regional Transmission System (RTS) awarded Siemens Power Transmission and Distribution the contract to construct the high-voltage direct-current (HVDC) transmission link between Sayreville, New Jersey and North Hempstead in Long Island, New York.

The project will be implemented by Siemens, who will engineer and supply the HVDC system and Milan-based Pirelli Energy Cables and Systems, which will provide the 65-mile long submarine power cable. Construction on the $400 million project will begin in August 2005 and the system will begin operation in mid-2007.

In addition to providing technological expertise, studies, and engineering services during the project development, Siemens will provide the initial operation and maintenance services for the system during a five year period.
