Abstract: A combined cycle power plant includes a gas turbine engine that includes a compressor having a compressor inlet, a compressor outlet, and an interstage inlet defined therebetween. The turbine also includes a turbine outlet configured to discharge a first exhaust gas stream therefrom. A heat recovery steam generator is configured to receive the first exhaust gas stream, extract heat from the first exhaust gas stream, and discharge a second exhaust gas stream therefrom. Either a recirculation compressor pressurizes a first portion of the second exhaust gas stream for recirculation towards the compressor interstage inlet, or an admission compressor pressurizes an air stream directed towards the compressor interstage inlet. A first cooler cools the stream directed to the compressor, thereby defining a cooled stream, wherein the first cooler provides the cooled stream to the interstage inlet of the compressor.
