Hellenic Cables Delivers for Dominion Energy

Hellenic Cables has completed the cable manufacturing and loading for shipment of inter-array cables for the Coastal Virginia Offshore Wind (CVOW), executing the contract awarded by Dominion Energy for the partial supply of array cables for the 2.6 GW project.

Hellenic Cables was responsible for the design, supply, and storage of approximately 50 kilometres of 66 kV, XLPE insulated submarine inter-array cables, connecting the wind turbines to the offshore substation.

”Hellenic Cables is a global leader and brings years of experience to help us deliver clean, renewable energy to our Virginia customers,” said Joshua Bennett, Dominion Energy’s vice president of offshore wind.

The cables have been manufactured in Hellenic Cables’ submarine cable production facility in Corinth, Greece, over an extended period.

”We are proud to support Dominion Energy in this flagship project, one of the first commercial-scale offshore wind projects in the US, with our world-class cable design and manufacturing expertise. In doing so, we are doing our part in enabling the clean energy transition in Virginia, the United States and the world,” said Alexis Alexiou, CEO of Cenergy Holdings and Hellenic Cables.

With this award, Hellenic Cables said the company further consolidated its presence in the US offshore wind market, following the award of Mayflower Wind array cables scope in early 2020. The company has also established Hellenic Cables America Inc., a wholly-owned subsidiary to provide its US customers with direct support and expertise throughout the entire lifetime of their projects.
