The invention relates to a method for operating a combined-cycle power plant with cogeneration, in which method combustion air is inducted in at least one gas turbine, is compressed and is fed to at least one combustion chamber for combustion of a fuel, and the resultant exhaust gas is expanded in at least one turbine producing work, and in which method the exhaust gas which emerges from the at least one turbine is fed through a heat recovery steam generator in order to generate steam, which heat recovery steam generator is part of a water-steam circuit with at least one steam turbine, a condenser, a feedwater tank and a feedwater pump, wherein heat is produced by extraction of steam from the at least one steam turbine. In a method such as this, simple decoupling of heat and electricity production, which is advantageous for operation, is achieved in that the steam can be selectively extracted from the at least one steam turbine as low-pressure steam or intermediate-pressure steam, and in that the steam extraction is switched from low-pressure steam to intermediate-pressure steam in order to restrict the electricity production.
