A method and system for generating power include using a cogeneration power system having a gas turbine. The gas turbine has a compressor section for receiving air to be compressed. The compressed air is fed to a combustor section where it is mixed with fuel and the fuel is burned to produce heated combustion gas. The heated combustion gas is expanded in an expander section to generate shaft work which is used to drive a generator or alternator for producing electric power. The heated combustion gas leaves the expander as turbine exhaust which is cooled by transferring at least part of its heat to the air ahead of the combustor.
