1. A method for operating a gas turbine engine, said method comprising:

  • channeling compressed airflow discharged from a first compressor through an intercooler having a cooling medium flowing therethrough, wherein the first compressor is coupled to a first turbine via a first shaft;

    channeling the compressed airflow discharged from the intercooler into a second compressor, wherein the second compressor is coupled to a second turbine via a second shaft;

    channeling water through the intercooler to facilitate increasing an operating temperature of the water; and

    channeling the discharged water directly from the intercooler in its entirety into a combustor to facilitate increasing a thermal efficiency of the gas turbine engine and to facilitate reducing nitrogen oxide emissions and channeling fuel through the intercooler to facilitate increasing an operating temperature of the fuel.
