1. A power generation installation, at least comprising:
at least one gas turbine respectively having an exhaust gas facility, in particular only one gas turbine,
at least one generator,
at least one steam turbine, wherein the steam turbine comprises either a single steam turbine or a steam turbine set comprised of a plurality of steam turbines, to be selected from: high-pressure turbine(s) and/or medium-pressure turbine(s) and/or low-pressure turbine(s),
at least one thermal energy accumulator, in particular only one thermal energy accumulator,
wherein, via a bypass stack of the exhaust gas facility of the respective gas turbine, hot exhaust gas from the gas turbine, preferably directly, can be fed into the at least one thermal energy accumulator,
wherein the thermal energy accumulator has sufficient capacity to permit the operation of the steam turbine in isolation, wherein, in particular, said capacity is at least 1 GWh and, more particularly, is at least 2 GWh, for the storage of thermal energy from exhaust gas in the thermal energy accumulator;
wherein a heat recovery system is provided, into which hot exhaust gas from the gas turbine and/or steam from the steam turbine and/or energy from the thermal energy accumulator to be admitted;
wherein the hot exhaust gas from the gas turbine is admitted to the heat recovery system via at least one bypass included in the exhaust gas facility.
