A combustion turbine power generation system 10 includes a combustion turbine assembly 11 including a main compressor 12 constructed and arranged to receive ambient inlet air, a main expansion turbine 14 operatively associated with the main compressor, a combustor 16 constructed and arranged to receive compressed air from the main compressor and to feed the main expansion turbine, and an electric generator 15 associated with the main expansion turbine for generating electric power. Pressure reducing structure 28 is constructed and arranged to reduce pressure of compressed air from a source of compressed air to atmospheric pressure and thus to reduce a temperature of the compressed air from the source of compressed air to a temperature below ambient temperature when exhausted from the pressure reducing structure. Structure 32 is associated with the pressure reducing structure to permit mixing of the air exhausted from the pressure reducing structure and the ambient inlet air to reduce a temperature of inlet air to the main compressor and thus increase the combustion turbine assembly power.
