Thermal power station and method for generating electric power in a thermal power station

A thermal power station comprising

• (a) at least one thermal energy storage having a housing, a storage chamber with heat storage material inside the storage chamber and a fluid inlet port fluidically connected to the storage chamber and a fluid outlet port fluidically connected to the storage chamber, and
• (b) a Brayton cycle heat engine comprising a gas turbine, a cooler and a compressor connected with each other by means of a closed cycle containing a second working fluid,
• whereby
• (c) the Brayton cycle heat engine further comprises a control unit arranged for operating the Brayton cycle heat engine according to a Brayton cycle,
• (d) the gas turbine is thermally coupled to the at least one thermal energy storage by means of a first heat exchanger and a first working fluid, the first working fluid being different from the second working fluid, and
• (e) the gas turbine is connected to a generator for producing electrical power by means of the thermal energy from the thermal energy storage.
