PORTSMOUTH, Va. (AP) - Dominion Energy Virginia has announced plans to partner with Denmark's DONG Energy to build two wind turbines off the coast of Virginia Beach.

Dominion announced Monday that the six-megawatt turbines will be built approximately 27 miles off the coast on a site leased by the state.

It says the project will provide operational, weather and environmental experience to help open the door to larger-scale wind farm development on a much larger adjacent site.

Engineering and development work on the Coastal Virginia Offshore Wind project is expected to begin immediately with installation targeted for 2020.

Offshore wind energy is a fledgling industry in the U.S., which lags far behind northern European nations. The nation's first offshore wind farm opened off the coast Rhode Island in December.
