Abstract. This study investigates two methods of transforming intermittent wind electricity into firm baseload capacity: (1) using electricity from natural gas combined-cycle (NGCC) power plants and (2) using electricity from compressed air energy storage (CAES) power plants.

3.1.5 Compressed Air Storage. Compressed Air Energy Storage (CAES) is an option in which the pressure energy is stored by compressing a gas, generally air, into a high pressure reservoir. The compressed air is expanded into a turbine to derive mechanical energy and hence run an electrical generator.
During peak demand periods, the compressed air is released from the pressurized energy-storage system and used to drive turbines to produce electricity. CAES technology requires the matching of operating pressure and flow rate of a geological storage vessel to that required by the turbo-generator equipment.
