Abstract: The invention relates to a method for temporary increasing the power of a gas turbine, which is part of a combined-cycle power plant, wherein the exhaust gas of the gas turbine is used in a heat recovery steam generator to generate steam for a water/steam cycle including a steam turbine with a high pressure steam turbine, an intermediate pressure steam turbine and a low pressure steam turbine, whereby the method comprises the step of injecting steam from the water/steam cycle at a predetermined injection pressure into the gas turbine. The efficiency is improved by taking steam of a lower pressure than the predetermined injection pressure from the water/steam cycle, increasing the pressure of the steam taken from the water/steam cycle to the predetermined injection pressure by subjecting it in separate compressing means to a compression step, and injecting the compressed steam into the gas turbine.
