Coastal Virginia Offshore Wind

Dominion Energy’s dedication to a clean environment continues to be reflected in renewable energy initiatives such as our CVOW project. It will be only the second offshore wind project in the nation and the first owned by an electric utility company.

It is also an important stepping stone toward commercial-scale offshore wind development, furthering Dominion Energy’s commitment to 3,000 megawatts of solar and wind energy under development or in operation by the beginning of 2022.

The CVOW project calls for development of two 6-megawatt wind turbines on a site leased by the Virginia Department of Mines Minerals and Energy (DMME). Dominion Energy has an agreement with DMME to build and operate the turbines within the 2,135-acre site, which lies 27 miles off the coast of Virginia Beach.

On November 2, 2018 the Virginia State Corporation Commission approved the project and granted a certificate of public convenience and necessity to construct and operate the associated Virginia Interconnect Facilities.

We have contracted with a global wind leader - Ørsted Energy of Denmark - for construction of the two turbines. And Dominion Energy has selected the L.E. Myers Company to perform onshore electrical design and construction.

The CVOW project builds on earlier work carried out under the Virginia Offshore Wind Technology Assessment Project (VOWTAP), which was started five years ago in an effort to lower the cost of offshore wind and test new technologies.

Much of the work performed under VOWTAP is still applicable, including geophysical and geotechnical investigation of the sea floor for the turbine sites and export cable route, metocean studies including hurricane and breaking wave studies and seabed mobility studies.

CVOW Construction Updates

As of Summer 2020 approaches, onshore and offshore construction activities will near completion on the Coastal Virginia Offshore Wind pilot project!

The two, 6-megawatt turbines are scheduled to be installed 27 miles off the coast of Virginia Beach this spring. In addition to the turbines, the CVOW project calls for a power cable to bring the clean energy to land. It will be buried under the seabed for much of its length but will ultimately come ashore through a 1,000-meter conduit installed under the beach.

Construction of the project’s two turbines will begin when an installation vessel arrives from Europe bearing the foundation pieces. Once work on the turbine substructures is complete, this vessel will depart to pick up additional components to install the turbines.

Installation, commissioning, and testing of CVOW’s two turbines will continue during the summer once the vessel returns to the project site. Meanwhile, a group of smaller ships will oversee final preparations for the power cable – completing its trenching and burial and then connecting it to Dominion Energy’s onshore infrastructure.

Dominion Energy expects to finish all this work and begin harnessing offshore wind energy by late 2020.

Commercial Offshore Wind Plans

Along with clean energy, the CVOW project will provide Dominion Energy valuable experience in managing offshore wind resources. Specifically, it will provide critical permitting, design, installation, and operational experience as it is the first project to be installed in federal waters under the Bureau of Ocean Energy Management (BOEM) process.

This will further inform development for large-scale commercial wind deployment in the adjacent Virginia Wind Energy Area leased by Dominion Energy from BOEM. It will also help create the expertise and the necessary domestic supply chains that will ultimately lower the costs of offshore wind development.

We filed an interconnection request with PJM, the regional transmission organization that coordinates the electrical grid in all or parts of 13 states and Washington, D.C., to bring online more than 2,600MW of offshore wind. This commercial offshore wind project would be installed in three phases of approximately 880MW each.

Pending regulatory approval, the first phase is expected to begin delivery of renewable energy in 2024, with additional phases coming online in 2025 and 2026. All three phases combined will provide enough energy to serve more than 650,000 customers.

This will be the largest single offshore wind project in the nation. Each 880MW phase is expected to bring more than 70 turbines, all of which will be located more than 27 miles off Virginia Beach.
