Virginia DEQ reviews application for 750-MW gas, solar plant

The Virginia Department of Environmental Quality (DEQ) is reviewing an air permit application for a 750-MW natural gas power plant and solar project that has been proposed for Loudoun County, Va.

Green Energy Partners/Stonewall LLC has proposed to build the plant outside of Leesburg, which is located in the Virginia suburbs of Washington, D.C. A public briefing was held on the project Sept. 24 in Leesburg, according to a public notice published in local newspapers.

The plant would be built in an industrial area near Leesburg Airport and Luck Stone Quarry. The original application filed in 2010 sought to permit a larger, 1,100-MW facility in the same location.

The updated proposal calls for a nominal 750-MW two-on-one gas turbine combined-cycle plant with a photovoltaic solar array. The facility will use up to 5 million gallons per day of waste-water effluent for cooling water in the plant’s mechanical draft cooling tower.

It will also include a zero-liquid discharge system (other than storm-water runoff). The facility will use either GE 7FA.05 or Siemens SGT6-5000F5 combustion turbine technology.

Green Energy Partners also said recently that the project would be co-developed by Bechtel, one of the largest engineering and construction companies in the world. “I am very pleased to have found such a partner in Bechtel, a company that is recognized worldwide as an industry leader,” said John Andrews II, the Managing Member of Green Energy Partners/Stonewall.

The Green Energy firm received a unanimous vote in favor of the project from the Loudoun County Board of Supervisors in April 2010. The board approved the land use zoning approval for the intermediate load and peak demand facility.

A Virginia DEQ official said Sept. 28 that the state is waiting for Green Energy Partners to submit detailed air modeling data. Once that information is submitted, and the DEQ decides the submission is complete, the state would then have 30 days to review it.

The subsequent step would be issuance of a proposed air permit, the DEQ official told GenerationHub.

A Sept. 28 article in the Washington Business Journal placed the cost of the power plant at an estimated $600m.
