A method of operating a thermal power plant, such as a gas turbine power plant, in which a rotary unit, such as at least one gas turbine stage, is driven by burning gaseous fuel inside a combustion chamber, with hot gases being formed, the rotary energy of which rotary unit is converted into another form of energy, such as into electrical energy. A load set point (L) of the thermal power plant is set by regulating the quantity of gaseous fuel fed to the combustion process. The thermal power plant is operated at a load set point (L), provided the gaseous fuel is fed to the combustion process through a gas line at a gas pressure p<SUB>gas</SUB>, with <?in-line-formulae description="In-line Formulae" end="lead"?>p<SUB>gas</SUB>>p<SUB>action limit</SUB>(L),<?in-line-formulae description="In-line Formulae" end="tail"?> where p<SUB>action limit</SUB>(L) represents a pressure value which depends at least on the load set point (L) of the thermal power plant.
