Yards Creek Generating Station is pumped-storage hydroelectric plant in Blairstown and Pahaquarry in Warren County, New Jersey The facility is jointed owned by subsidiaries of Public Service Enterprise Group and FirstEnergy. It has an installed capacity of 420 MW.LocationThe facility is located in the Delaware Water Gap region of the New Jersey Skylands. When built the complex stretched in Pahaquarry, which got its name from the word Pahaquarra, which was a derivation of the Native American word Pahaqualong, which meant "the place between the mountains beside the waters".

Yards Creek consists of two reservoirs created by earth-fill embankment dams. The upper and lower reservoirs are separated by an elevation of 700ft. Water is conveyed between the plant & the Upper Reservoir via an 18’ diameter 1,800’ long exposed steel pipe At full station load, approximately 4 million gpm of water is released (9000 cfs). The full upper reservoir will last 5.7 hours at Hydraulic Turbine nameplate capacity. The storage facility provides energy regulation and spinning reserve during on-peak hours, and it provides an energy sink off-peak (11P.M. -7 A.M.) to allow fossil and nuclear plants to remain more fully loaded.
