In a power generation plant having at least one gas turbine cycle with heat-recovery boiler ( 4 ) and at least one steam turbine cycle operated via the heat-recovery boiler ( 4 ), the gas turbine cycle being designed to be semi-closed and essentially free of emissions and essentially comprising a compressor ( 1 ), a combustion chamber ( 2 ) arranged downstream of the compressor ( 1 ), a gas turbine ( 3 ) arranged downstream of the combustion chamber ( 2 ), a heat-recovery boiler ( 4 ) arranged downstream of the gas turbine ( 3 ), and at least one generator ( 8 ) coupled to the gas turbine ( 3 ), modes of operation with the gas turbine cycle stopped and start-up using fresh air are made possible by first means ( 12 ) being arranged which alternatively or additionally allow hot gas to be fed into the hot-gas path ( 23 ) between gas turbine ( 3 ) and heat-recovery boiler ( 4 ), and by second means ( 15 ) being arranged which alternatively or additionally allow exhaust gas to be expelled from the exhaust-gas path ( 40 ) downstream of the heat-recovery boiler ( 4 ).
