Dominion Energy on June 29 said that it has completed the construction of the two-turbine, 12-MW Coastal Virginia Offshore Wind (CVOW) pilot project 27 miles off Virginia Beach, Va.
The company said that the project is the first offshore wind farm to be approved by the Bureau of Ocean Energy Management (BOEM) and installed in federal waters, as well as the second one built in the United States.
Dominion said that the turbines will undergo acceptance testing before being energized later this summer and producing enough renewable energy, at peak output, to power 3,000 homes in Virginia.
The company noted that it will apply the permitting, design, installation, and operations experience from the pilot project to its proposed 2,600-MW commercial project, which is on track to begin construction in 2024. Survey and geotechnical work continues on the 2.6-GW, full-scale wind development, the company said, adding that the surveys will support the development of that project’s Construction and Operations Plan to be submitted to BOEM later this year.
Dominion noted that it named Siemens Gamesa Renewable Energy (SGRE) its preferred wind turbine supplier for the project earlier this year, with SGRE announcing that the project will use its new SG 14-222 DD turbine for the project. About 180 of the more than 800-foot-tall wind turbines are expected to be deployed in the project, Dominion said.
Of the pilot project, the company noted that Ørsted is serving as the offshore engineering, procurement and construction lead for the project, while the L. E. Myers Company with members of the International Brotherhood of Electrical Workers, performed the onshore construction work.
The Virginia State Corporation Commission approved the project in November 2018, the company said, adding that onshore construction of the electrical interconnection facilities, as well as the half-mile conduit that holds the final stretch of cable connecting the turbines 27 miles off the coast to a company substation near Camp Pendleton, was completed earlier this year.
As TransmissionHub reported, Dominion on Sept. 19, 2019, said that it has filed an application with PJM Interconnection to interconnect offshore wind turbines to the transmission grid as part of Dominion Energy’s proposal to build “the largest offshore wind development in the country.”
Dominion Energy said at the time that building on an expected successful deployment of the CVOW project in 2020, the company plans to move forward with its commercial offshore wind project in three phases, each totaling 880 MW, with the first phase of the buildout supporting initial generation of wind energy by 2024. Additional phases will come online in 2025 and 2026, totaling more than 2,600 MW of energy, the company said.
Dominion Energy spokesperson Jeremy Slayton on Sept. 19, 2019, told TransmissionHub: “We estimate the cost to be $2.6 billion per phase – [t]he current cost estimates are based on a European supply chain and we will relentlessly pursue a US-based supply chain and workforce anchored in Hampton Roads to drive down costs.”
Slayton said that in addition to the company submitting its Construction and Operations Plan for approval by the BOEM, the Virginia commission also needs to approve the project.
