Hydro, nuclear, and conventional steam power require a high use factor for good economy, and it would therefore be an advantage if energy could be stored during low demand periods for use as variable peak power. A pumped storage station has this characteristic, but is passive, i.e., it produces no active energy but transfers low cost energy to high value peak power periods with the least possible losses. The air storage gas turbine power plant described herein is both passive and active, i.e., can transfer low cost energy to peak time energy and in addition produce an active energy output. The air storage is of the hydrostatic pressurized, excavated cavern type, which gives the widest possible choice in geographic location. The specific cost of the plant in $/kw is approximately 70 percent of a conventional gas turbine installation and generally lower than for pumped storage.
