Beschreibung
Zusammenfassung:	The invention relates to a method for operation of a combined-cycle power plant with cogeneration, in which method combustion air is inducted in at least one gas turbine, and in which method the exhaust gas emerging from the at least one turbine is passed through a heat recovery steam generator (HRSG) in order to generate steam. The electricity production can be decoupled from the steam production in order to restrict the electricity production while the heat provided by steam extraction remains at a constant level. A portion of the inducted combustion air can be passed through at least one turbine to the HRSG without being involved in the combustion of the fuel in the gas turbine. This portion of the combustion air can be used to operate at least one supplementary firing in the heat recovery steam generator.
