GREEN ENERGY PARTNERS/STONEWALL
SOLAR AND NATURAL GAS-FIRED POWER PLANT
AT LEESBURG, VA

Updated 5/10/2010

 

Green Energy Partners is proposing to build a nominal 1000 megawatt (MW) power plant in Loudoun County, Virginia.  The plant will be located south-southeast of the Town of Leesburg Airport and north of the Dulles Toll Road.  The plant will include four natural gas-fired gas combustion turbine generators.  Two will be in combined cycle with heat recovery steam generators (HRSGs) and two simple cycle peaking units.  Exhaust gases from the combined cycle units will be sent to HRSGs, and steam from the HRSGs will be routed to a steam turbine generator to produce additional power.

A summary of the proposed air pollution sources is as follows:

Two combined cycle natural gas-fired combustion units each rated at 210 MW per turbine at ISO.  The turbine NOx emissions will be controlled by low-NOx burners and Selective Catalytic Reduction (SCR) for a rate of 2 parts per million (ppm).

The turbines will be vented to a heat recovery steam generator (HRSG) with a natural gas-fired duct burner that is rated at 206 MMBtu.  The steam generated by the HRSG’s will be vented to steam turbine with a rated electrical generating capacity of 270 MW at ISO.                  

Two simple cycle natural gas-fired combustion turbines that are rated at 212 MW per turbine at ISO.  The turbine NOx emissions will be controlled by low NOx burners, and good operating practices, and will have an emission rate of 9 ppm.           

One cooling tower that will use a total cooling water circulating rate 187,400 gallons per minute (gpm)

One auxiliary natural gas-fired steam boiler that will be rated at 75 MMBtu/hr Heat Input Capacity.  NOx emissions will be controlled by a low NOx burner, and CO and PM-10 will be controlled by good operating practices.

One emergency fire water pump rated at 330 HP Engine. NOx emissions will be controlled by a low NOx burner, and CO and PM-10 will be controlled by good operating practices.                         

One emergency engine-generator rated at 2,100 HP Engine / 1,500 ekW Generator. NOx emissions will be controlled by a low NOx burner, and CO and PM-10 will be controlled by good operating practices.  

The potential emission levels for the facility will require Green Energy Partners to obtain both a major source non-attainment area new source review (NSR) permit for ozone, and a PSD permit for NOx, PM and CO.
