Google supports groundbreaking HVDC project


Google is one sponsor supporting the development of the New Jersey Energy Link, the first offshore backbone electricity transmission system proposed in the United States. The project will improve the reliability of New Jersey's power grid, and help lower electricity prices by delivering both offshore wind and conventional electricity where and when it is needed.

The next decade will see the three-phase development of Atlantic Wind Connection's New Jersey Energy Link -- an offshore electrical transmission cable, buried under the ocean, linking energy resources and users in northern, central and southern New Jersey.

The cable will span the length of New Jersey and carry up to 3,000 MW of electricity. Two onshore convertor stations and one offshore converter station will make up the New Jersey Energy Link backbone. Advanced HVDC converter technology and high voltage DC (HVDC) cables bring power from offshore wind turbines to the onshore converter stations.

Led by independent transmission company Trans-Elect and Atlantic Grid, this multi-terminal HVDC offshore network will transform the 138 kV or 230 kV alternating current output from offshore wind farm electric service platforms into DC for transmission at 320 kV DC to onshore converters connected to the PJM grid.
