US-based energy company Dominion Energy has filed for approval from the Virginia State Corporation Commission to build a 2.6GW offshore wind project in Virginia.

The Coastal Virginia Offshore Wind (CVOW) project will have the capacity to power 660,000 homes with clean energy.

It is estimated that the project will require a $9.8bn investment, but all costs are subject to State Corporation Commission approval.

The project is expected to create 1,100 jobs once operational, as well as generating local and state tax revenue of around $11m and almost $210m in economic benefits each year.

Dominion Energy initially filed plans for the project last December.

In a statement, the company said: “The filing keeps the project on schedule and builds on recent economic development announcements, such as the Siemens Gamesa Renewable Energy turbine blade factory at the Portsmouth Marine Terminal and Dominion Energy’s investment in the only US-flagged offshore wind turbine installation vessel, that establish Virginia as a leader in this rapidly growing new industry.”

In the filing, Dominion Energy also sought approval to build around 17 miles of transmission lines, as well as ancillary onshore infrastructure to supply energy from the offshore wind facility to homes and businesses across Virginia.

The company has also proposed a transmission interconnection route and alternative options for consideration.

According to Dominion Energy, the proposed route is the shortest among potential options and was identified after a thorough study and consultations with Virginia Beach and Chesapeake officials, as well as land managers, local communities, state and federal agencies.

Dominion Energy chair, president and CEO Robert M Blue said: “In addition to solar, storage and nuclear, offshore wind is a key component of our strategy and a game changer for the Hampton Roads economy.

“CVOW is making Virginia the hub for this new industry. Virginia will host the first offshore wind turbine blade factory in the US and be the home port for the only Jones Act-compliant offshore wind installation vessel.”
