An electric power generation system including a power shaft assembly including a combustion turbine with a compressor, an expansion turbine, a combustor feeding the expansion turbine, an electrical generator, and a shaft for coupling the expansion turbine to drive the compressor and the electrical generator; an additional shaft assembly including an intercooler, a compressor, an expansion turbine, a combustor feeding the expansion turbine, and a driver for driving the compressor of the additional shaft assembly, the compressor of the additional shaft assembly being constructed and arranged to have a pressure ratio greater than a pressure ratio of the expansion turbine of the additional shaft assembly which is fluid connected to the power shaft assembly for pressure unloading the compressor of the power shaft assembly; a recuperator; and an exhaust stack. The power shaft assembly, the additional shaft assembly and the recuperator are connected to define a thermal cycle with an air and gas path that passes through the compressor of the power shaft assembly, through the intercooler and compressor of the additional shaft assembly, through the recuperator, through the combustor and expansion turbine of the additional shaft assembly and through the combustor and expansion turbine of the power shaft assembly, and finally exhausting through the recuperator to the exhaust stack.
