Profile

Operating status: West Deptford Energy Station is currently operating; a closure or retirement is listed for 2026.
Grid role: Natural-gas combined-cycle generation resource participating in PJM.
Context: The station's integrated black-start system was described as a practically unprecedented power-sector milestone because it can restart other connected power plants; the project was also named an Engineering News-Record Best Project of 2015.
Physical build: Natural-gas combined-cycle plant with a 2x1 configuration: two Siemens SGT6-5000F combustion-turbine generator units, two heat-recovery steam generators, one steam-turbine generator, complete balance of plant, commissioning/startup, and a 230-kV switchyard. The EPC scope was reported at 738 MW; regulatory design criteria describe nominal output up to 750 MW. The black-start installation added three Caterpillar diesel engine-driven generators rated at 4 MW each in sound-reducing enclosures, plus diesel-engine controls, facility-control modifications, site preparation, paving, fencing, and real-property improvements. Regulatory records also identify a 40-MMBtu/hr auxiliary boiler, one 1,000-kW emergency generator, a diesel fire pump, diesel storage tanks, and cooling towers.
