Abstract: The invention discloses a method for operating a combined cycle power plant with an integrated CO2 capture unit, wherein flue gas of a gas turbine is led along an flue gas path through a heat recovery steam generator, a flue gas cooling circuit and a CO2 absorber. A reduction in effort is achieved by operating the gas turbine to have a back-pressure at its exit, which compensates most or all of the pressure loss of the flue gas along the flue gas path.
