The purpose of this project is to provide approximately 2.6 GW of clean, reliable offshore wind energy, increasing the amount and availability of renewable energy to Virginia customers, creating the opportunity to provide clean, reliable energy and to offer substantial economic and environmental benefits to the Hampton Roads region. This project represents a viable and needed opportunity for Virginia to obtain clean renewable energy and realize its economic and environmental goals.


In January 2022, Hellenic Cables  announced the successful completion of manufacturing and load out of the cables required by Dominion Energy for the partial supply of inter-array cables for the Coastal Virginia Offshore Wind (CVOW) commercial project.

The cables have been manufactured in Hellenic Cables’ state-of-the-art submarine cable production facility in Corinth, Greece.
