A method for supplying power to a remote load includes coupling a gas turbine engine to a vessel that is not used to provide propulsion for the vessel, coupling a generator to the gas turbine engine, coupling an intercooler system downstream from a first compressor such that compressed air discharged from the first compressor is channeled therethrough, the intercooler system includes an intercooler and a first heat exchanger, channeling a first working fluid through the intercooler to facilitate reducing an operating temperature of air discharged from the intercooler to a second compressor, channeling a second working fluid flowing through the first heat exchanger to extract energy from the first working fluid to facilitate reducing an operating temperature of the first working fluid, and operating the gas turbine engine and generator to supply power to a load that is located remotely from the vessel.
