A 750-MW (nominal), gas-fired power project in Virginia will be configured with two combustion turbines, two heat recovery steam generators with duct burners and one steam turbine generator.
That is according to Sept. 20 testimony from Ross Metersky, Vice President, Business Development with Panda Power Funds and Development Manager for Green Energy Partners/Stonewall LLC. The testimony was part of Green Energy’s application with the Virginia State Corporation Commission for a Certificate of Public Convenience and Necessity (CPCN) for this project, located in Loudoun County, Va.
The project is to be located in Loudoun County on a 101-acre parcel consolidation zoned for industrial uses located south-southeast of the Leesburg Executive Airport and north of the Dulles Greenway. Immediately surrounding the site on the south and west are 200 acres of land zoned for industrial uses. The property east of the site is owned by Luck Stone Corp. and is zoned for mineral extraction. North of the site is the floodplain of Sycolin Creek and Loudoun County owned open space recreational area.
The use of the site for the power project was approved by the Loudoun County Board of Supervisors in April 2010 and conditional approval for the project’s site plan was granted by Loudoun County in October 2012.
Because the project’s air permit issued by the Virginia Department of Environmental Quality approved the use of either Siemens‘ SGT6-500OF(5) combustion turbines (CT) or General Electric‘s 7FA.05 CT, the project currently has flexibility in selecting a CT manufacturer. An auxiliary boiler will be provided for plant startup and shutdown needs.
The CTs will use low-NOx combustion technology and will be equipped with selective catalytic reduction (SCR) systems to control NOx emissions. High-efficiency combustion design, with oxidation catalyst, will be employed to control CO and VOC emissions. The exclusive use of pipeline-quality natural gas will minimize particulate matter (PM)/PMIO, SO2, and sulfuric acid (H2SO4) air emissions.
Two nearby gas pipelines can supply plant needs. One pipeline is owned by Dominion Transmission and the other is owned by Columbia Gas Transmission. Pipeline laterals and a regulation and metering station will be constructed on the plant site to interconnect to these pipelines. The project company plans to secure firm transportation by contracting with gas supplier(s) that own or control firm transportation service on either or both of the Dominion or Columbia interstate pipelines.
The site is currently traversed by three existing Virginia Electric and Power d/b/a Dominion Virginia Power transmission lines. The project is proposed to interconnect on the Pleasant View-to-Brambleton 230-kV TL201 transmission line that traverses the property. This interconnection will be accomplished through facilities constructed on the site.
Preliminary feasibility and system impact studies conducted by PJM Interconnection indicate that the impacts on the transmission system would be largely local. It is currently anticipated that a more detailed facility study will be completed in October 2013 regarding the interconnection costs for the project.
The current members of Green Energy Partners/Stonewall LLC are: GEP/S Holdings LLC of Hamilton, Va.; Bechtel Development of Reston, Va.; and Panda Midatlantic Development LLC of Dallas, Texas. Panda Midatlantic Development is the majority owner and managing partner of Green Energy Partners/Stonewall. Prior to construction, Panda Midatlantic Development will become the sole member of Green Energy Partners/Stonewall.
GEP/S Holdings LLC is principally owned by John Andrews II, an experienced real estate developer based in Loudoun County.
The facility represents an estimated total capital expenditure of about $500m, excluding certain owner and financing costs, from 2014 through 2017. Commercial operation is expected by March 2017.
