A method for primary regulation of a combined gas and steam turbine installation in network operation, wherein the combined gas and steam turbine installation includes a gas turbine and a steam turbine arranged along at least one shaft includes operating at least one steam turbine actuating valve on a restricted basis along a working steam supply line to at least one pressure stage of the steam turbine so as to provide a steady-state steam turbine reserve power, wherein the at least one steam turbine actuating valve is changed to a less restricted state if a network frequency decreases so as to require network frequency support.
