Claim Text:
1. A method for operating a gas power plant, comprising a gas turbine, which has a compressor stage and a turbine stage, and is connected to a generator via a shaft, wherein the generator is connected to an electricity network and designed to also be operated as a motor, which method comprises the following steps: operating the generator as a motor to consume electrical power from the electricity network for the rotational operation of the shaft; feeding fuel to the gas turbine during operation of the generator as a motor in a quantity which is lower than a quantity which is fed to the gas turbine when electrical power is supplied to the electricity network; simultaneously diverting of the gas flow which discharges from the turbine stage during operation of the generator as a motor; feeding this gas flow to a first heat exchanger for transferring thermal energy from the gas flow to a heat exchanger fluid; and feeding the heat exchanger fluid to a thermal store.
