Under the Coastal Virginia Offshore Wind (CVOW) Pilot Project, Tetra Tech served as the lead environmental consultant for Dominion Energy’s 12-megawatt offshore wind project located 27 miles off the coast of Virginia, and facilitated all federal and state permitting work and construction compliance monitoring and training.

Tetra Tech provided preliminary siting, permitting, and environmental analysis for this 2-turbine, 12-megawatt (MW) pilot project, including geophysical, geotechnical, and biological surveys and studies; permit application preparation; stakeholder and agency outreach and consultation support; preparation of a Research Activities Plan to support the Bureau of Ocean Energy Management (BOEM) evaluation under the National Environmental Policy Act; and compliance and coordination for construction.

These were the first wind turbines to be installed in U.S. federal waters and only the second offshore wind turbines installed anywhere in the United States. The turbines will provide clean renewable energy to approximately 3,000 homes at peak production. Tetra Tech guided many firsts with this project, including approval of a Research Activities Plan—a first-of-its kind environmental report that is the basis for the Bureau of Ocean Energy Management evaluation under the National Environmental Policy Act—and issuance of the first right-of-way grant for renewable energy activities.

The CVOW Pilot Project was the first project to fully navigate and implement the regulations under 30 Code of Federal Regulations 585 for Renewable Energy and Alternate Uses of Existing Facilities on the Outer Continental Shelf, and has provided invaluable insight that can be leveraged to ensure a more efficient and effective process for developing commercial scale offshore wind projects in the United States.

Construction of the CVOW Pilot Project was completed in early August 2020 and commenced commercial operations later that same month.
