Dominion Energy has hit a major milestone in the construction of its Coastal Virginia Offshore Wind (CVOW) project. The company has put in place 78 monopile foundations and four offshore substation foundations during the first installation season, surpassing its initial target of 70 monopiles.
The 2.6-gigawatt (GW) project is located 27 miles off the coast of Virginia Beach and is the US’s largest offshore wind farm under construction.
When complete, CVOW will feature 176 turbines generating enough clean energy to power up to 660,000 homes. Dominion Energy expects the project to save customers $3 billion in fuel costs over the first decade of operation. Construction is on track and on budget, with a projected completion date in late 2026. The project is currently 43% finished.
For the next few months, Dominion will focus on installing the first offshore substation, laying export cables, continuing onshore transmission work, and placing transition pieces on top of monopiles to prepare for turbine installation in 2025.
The monopiles, which are single vertical steel cylinders that support the wind turbines, are being staged at Portsmouth Marine Terminal. They were manufactured by Rostock, Germany-based EEW SPC, and will support turbines supplied by Siemens Gamesa. Installation of the remaining monopiles will resume in May 2025 as planned.
The planned pause is to safeguard the endangered North Atlantic right whale during its migration period through the project area.
CVOW is also boosting Virginia’s economy. Nearly 1,000 workers from the state, including more than 800 in the Hampton Roads area, have been involved in the project so far. Once operational, the CVOW wind farm is expected to create over 1,000 local jobs for ongoing maintenance and operations.
