A method and apparatus for increasing power output and efficiency of gas turbines. Power output is enhanced and NOx emissions are lowered while heat rate penalties are minimized by adding nitrogen or a mixture of nitrogen and water vapor to the gas turbine in conjunction with the use of low pressure
