Abstract
A peaking/intermediate power plant is disclosed having a compression mode in which air is compressed and stored in a storage device and an expansion mode in which such stored compressed air is initially pre-heated by exhaust gas in a recuperator, expanded without combustion in a high pressure turbine, combined with fuel and combusted in a low pressure combustor, expanded in a low pressure turbine, and supplied to the recuperator as exhaust gas of sufficient temperature to heat the compressed air enough to eliminate the need for is combustion prior to supply to the high pressure turbine.
