In a power plant which is equipped with a gas turbine, fuel for the gas turbine is preheated by means of solar heat. The preheating is realized through the use of a heat transfer circuit. The use of an additional, second heat transfer circuit between the source for the solar heat and the first heat transfer circuit permits storage of the solar heat. The fuel preheating according to the invention permits in particular an increase in the efficiency of the power plant.

Method for increasing the efficiency of a power plant which is equipped with a gas turbine, and power plant for carrying out the method
