Abstract

A method for operating a gas power plant is provided, having a gas turbine which has a compressor stage and a turbine stage, and is connected to a generator via an axle, wherein the generator is designed to also be operated as a motor, wherein the method involves the operation of the generator as a motor for the rotatory operation of the axle, as well as a simultaneous discharge of the heated gas flow exiting from the turbine stage and routing of said gas flow to a first heat exchanger for the transfer of thermal energy from the gas flow to a heat exchanger fluid, wherein the heat exchanger fluid is provided to either discharge thermal energy to a heat accumulating medium or it can be used an accumulating medium itself for temporary storage.
