CAES typically use off-peak electricity to power compressors for storing energy in the form of compressed air in a vessel (i.e., a hard-rock cavern, salt cavern, or aquifer storage). The stored compressed air can be released into a gas turbine, saving air-compression energy that would, in a conventional gas turbine, be provided by natural gas.
