Cross Sound Cable

The Cross Sound Cable is a 24-mile HVDC submarine power cable between New Haven, Connecticut and Shoreham, Long Island New York. The line can transmit a maximum power of 330 MW at a voltage of 150 kV DC. The line is a bundle of cables that includes the HVDC transmission lines and fiber-optic cables for phone and Internet data transfer. The Cross Sound Cable was commissioned in 2002 and entered into continuous operation in 2005. The builders and first operators of the project, TransÉnergie HQ, a subsidiary of Hydro-Québec, and the United Illuminating Company, sold their interests in the cable to Babcock & Brown for approximately $213 million in February 2006.
