RICHMOND, Va. (AP) — Virginia is seeking to survey a vast expanse of the ocean floor and document wind, waves and wildlife offshore to smooth the way for development of wind turbines by energy companies.
The proposed exploration 27 miles off Virginia Beach encompasses 113,000 acres, or 133 square miles, in the federally designated wind development area. Eight companies have expressed an interest in building towering turbines there to capture wind for energy. The eight include Dominion Virginia Power, the state's largest utility, as well as international interests.
The Department of Mines, Minerals and Energy is proposing two initiatives. One seeks proposals by Oct. 17 to survey the ocean bottom to determine if it can hold massive support structures for wind turbines, which would rise hundreds of feet above the surface. The other involves building platforms along the edges of the commercial lease area.
The so-called metocean platforms would use instruments and human observers to map and measure wind speeds and direction, water levels, and bird and bat activity.
The initiatives are intended to spare developers the preliminary steps needed to create wind farms in offshore tracts overseen by the U.S. Department of the Interior and to create an environment for energy companies to move forward with wind energy plans, state officials said.
Companies already face daunting costs to develop wind energy in an ocean environment, such as the design and manufacture of turbine and blade components and ships to deliver and install them.
"If you don't know what is on the ocean floor, then your risk is exacerbated by that lack of knowledge," said Maureen Matsen, Gov. Bob McDonnell's top energy adviser and a member of a state authority promoting offshore development.
"That's what this is really about. It's about eliminating the uncertainty and reducing the risk."
