Updated Sept 4th 2025 — Uncertainty rocked the project in late August 2025 after the Trump Administration halted the 80% complete Revolution Wind project off the coast of Rhode Island and Connecticut. This halt raised questions about whether Dominion Energy‘s $10.9 billion Coastal Virginia Offshore Wind (CVOW) project in Virginia Beach will also be paused.
However, construction of the CVOW project – the largest offshore wind development in the U.S. – remains on track. Work on the onshore transmission systems kicked off in late 2023, while offshore installation activities began in early 2024. CVOW will have a total capacity of 2.6 GW, with 176 turbines planned to produce enough clean, renewable electricity to supply up to 660,000 homes.
According to Dominion Energy, the project is now nearly 60% finished. Once fully operational, it will meet about a quarter of Dominion’s residential electricity demand in Virginia. More recently, Dominion Energy also signed a 15-year Power Purchase Agreement (PPA) with Swift Current’s Prospect Power Battery Storage Project in Virginia. The BESS project also secured a $242 million financial close on 4th Sept 2025.
Trump tariffs may increase costs by $500 million
Reported on July 25 2025 — Tariffs on steel imports imposed by the Trump administration are projected to increase the project’s overall cost. Dominion spokesperson, Jeremy Slayton, noted that the tariffs had already added about $120 million through the second quarter of this year. This, Jeremy highlighted, could contribute an additional $500 million if they remain in place until the project’s completion.
16th April 2024 — The installation vessel of DP3 known as Orion which is under the ownership of the Belgian construction specialist known as DEME sailed out of Invergordon in Scotland and was headed to the U.S. Here, its involvement span around the installation of the monopile foundations at the Coastal Virginia Offshore Wind (CVOW) project.
On the 15th of April, DEME had also made a major announcement that Orion had finished monopole installation works at a Scottish wind farm known as Moray West. DEME also mentioned that the vessel was to start its journey across the Atlantic to the U.S. to commence the CVOW project in Virginia. This vessel had already foreseen deployment in the U.S. offshore wind market. It had done installation works on the offshore substation and monopolies located on the Vineyard 1 wind farm located off Massachusetts.
Referencing AIS data available online, Orion departed from the Port of Invergordon on the morning of 15th April and was expected to arrive at the Port of Halifax on April 24th. Orion was then expected to arrive at the Port of Norfolk in Virginia. The vessel then commence preparation for the installation of the 176 monopolies at the CVOW project site located approximately 27 miles from the coast of Virginia.
Capacity of the Coastal Virginia Offshore Wind Project
The CVOW project has a capacity of 2.6 GW. DEME secured a contract on the wind farm project when Dominion chose the consortium of DEME-Prysmian to serve as the Balance of Plant (BOP) contractor. As a BOP contractor, the consortium was tasked with the transportation and installation of foundations and substations. They also were involved in EPCI services of the inter-array and the export cables that would be at the Coastal Virginia Offshore Wind project. They held together the important bits of what is set to become the biggest commercial offshore wind farm in the United States.
Technology incorporated at Coastal Virginia Offshore Wind Project
Jan Klaasen, Business Unit Director Americas at DEME, mentioned the following, “A combination of technologies entailing the Vibro Hammer and the Impact Hammer are incorporated in the Coastal Virginia Offshore Wind project. This is also a combination of highly advanced noise mitigation technologies that will protect the marine mammals.”
EEW SPC undertook the production of the monopolies for this 2.6 GW offshore wind farm. EEW SPC had also already sent the first batch in September 2023 from its production unit in Rostock, Germany to the Port of Virginia’s Portsmouth Marine Terminal. The delivery works of the 176 transition pieces (TPs) is overseen by Denmark-based Bladt Industries .
