Dominion Energy (D - Get Report)  plans to build what it describes as the country's largest offshore wind development, offshore Virginia.

It says the project — which would include more than 220 wind turbines and power as many as 650,000 homes at peak — will provide more renewable energy and boost the offshore wind industry on the U.S. East Coast.

The Richmond, Va., utility company said it applied to the regional transmission organization, PJM, which coordinates the electrical grid in all or parts of 13 states and the District of Columbia, to interconnect the proposed turbines to the transmission grid.

"Dominion Energy's filing is a vital first step to move forward in developing Virginia's full offshore wind potential," the company stated.

The company said it's "aggressively pursuing" clean-energy projects by investing in solar and wind energy partnered with zero-carbon nuclear and low-carbon natural gas. 

It also has planned investments in battery storage, pumped hydroelectric storage and other resources that can support the intermittent nature of solar and wind.

If approved, the project would be located in the 112,800 acres Dominion Energy leases from the Bureau of Ocean Energy Management, 27 miles off the coast of Virginia Beach. 

Ocean-survey work is expected to begin in 2020, and a construction and operations plan will be submitted in 2022.

The project, generating a total of more than 2,600 megawatts of energy, would go online in three phases, in 2024, 2025 and 2026, Dominion said.

Dominion Energy shares were trading up 0.9% to $80.78 on Thursday.
