Abstract
A power plant system is provided having a high temperature battery, supplied with fluid via at least one supply line, for storing and releasing electrical energy, a gas turbine for generating electrical energy, and a heat exchanger which is designed to extract thermal energy from the exhaust stream of the gas turbine and transfer said thermal energy to the fluid, which fluid can be supplied after heat transfer to the high temperature battery via the at least one supply line.

1-11. (canceled)
A power plant system comprising
- a high-temperature battery, supplied with a fluid via at least one feed line, for storing and also for delivering electric energy,
- a gas turbine, with at least one compression stage for compressing air,
- a combustion chamber and at least one turbine stage, for generating electric energy, and
- a heat exchanger adapted for extracting thermal energy from the exhaust gas flow of the gas turbine and transferring said thermal energy to the fluid, which fluid is fed to the high-temperature battery via the at least one feed line after heat transfer has been carried out,
- wherein the high-temperature battery has a discharge line adapted for discharging the fluid from the high-temperature battery and for feeding said fluid to the exhaust gas flow of the gas turbine at a downstream point of the exhaust gas flow with regard to the heat exchanger.
