1. An energy generation plant, comprising:
a gas turbine comprising an exhaust gas apparatus,
a generator,
a thermal energy store,
wherein the generator is adapted to be driven by the gas turbine,
wherein hot exhaust gas from the gas turbine is adapted to be passed directly to the thermal energy store via the exhaust gas apparatus,
a power generating apparatus for using thermal energy from the thermal energy store to generate power, and
a circuit configured to receive air from the thermal energy store that has been cooled in the power generating apparatus into cold air, to deliver the cold air to the thermal energy store, to heat the cold air into heated air in the thermal energy store, and to return the heated air to the power generating apparatus.
