Abstract: Method for operating a combined-cycle power plant is provided. The plant includes at least a gas turbine and at least a steam power generation system. The plant activates at least one electric generator connectable to an electric grid, wherein the gas turbine includes a compressor. The steam power generation system includes a steam turbine, a heat recovery steam generator and a bypass line. The method is such that the gas turbine de-loads to a condition, where the compressor operates at its nominal speed. The method is such that the steam turbine de-loads in coordination with the de-load of the gas turbine, to a condition where the total load exported by the plant to the grid is substantially equal to zero, being both the gas turbine and the steam power generation system connected.
