Panda Power Funds’ Stonewall Energy Facility (pictured below) – a natural gas-fueled combined cycle power plant in Leesburg, Loudoun County, Virginia, USA – has achieved commercial operation. The project was implemented on a turnkey basis by Siemens in consortium with Bechtel, which reports that it was delivered ahead of schedule.

Stonewall is one of seven gas-fired power plant projects, totalling about 5.8 GW, awarded to Siemens by Panda Power Funds, including facilities in Texas, Pennsylvania and Virginia. Long-term service agreements with Siemens are also in place for all seven projects, including parts, inspections, and scheduled service/ maintenance, along with Siemens Power Diagnostics, part of Siemens’ Digital Services for Energy offering.

For the 778 MW Stonewall plant Siemens delivered the power island equipment, including two SGT6-5000F gas turbines, one SST6-5000 steam turbine with an SCon-4000 condenser, two SGen6-1000A generators, one SGen6-2000H generator and two NEM duct-fired heat recovery steam generators, along with the complete electrical system plus SPPA-T3000 instrumentation and control system.

The gas turbines, steam turbines and generators were manufactured at Siemens’ Charlotte Energy Hub, the global base for the company’s 60 Hz power generating equipment.

“We are very pleased with the way the plant is performing so soon after startup. Initial tests show Stonewall is already exceeding guarantees for both power output and efficiency”, said Todd W. Carter, CEO and senior partner of Panda Power Funds.

To secure funds for the Stonewall project, a finance package utilising senior debt, mezzanine debt and equity was obtained to cover the total project costs. In support of this package, Siemens’ Financial Services Division made a $75 million equity investment.

Bechtel provided project management, engineering, procurement, construction, and startup services.

The new facility uses what is described as “advanced emissions-control technology” and is cooled with treated wastewater, helping to conserve Virginia’s natural supply of drinking water and prevent discharge of nutrients into the Potomac River and Chesapeake Bay watershed.
