Abstract

Method for operating a combined-cycle power plant (1), the plant (1) comprising at least a gas turbine (2) and at least a steam power generation system (10), the plant (1) activating at least one electric generator (20) connectable to an electric grid (21), wherein the gas turbine (2) comprises a compressor (3) and wherein the steam power generation system (10) comprises a steam turbine (12), a heat recovery steam generator (11) and a bypass line (40), the method being such that the gas turbine (2) de-loads to a condition, where the compressor (3) operates at its nominal speed, the method being further such that the steam turbine (12) deloads in coordination with the de-load of the gas turbine (2), to a condition where the total load exported by the plant (1) to the grid (21) is substantially equal to zero, being both the gas turbine (2) and the steam power generation system (10) connected.
