The invention relates to a solar thermal power plant (1) comprising a solar collector steam generator unit (2), a solar collector steam superheater unit (4), a steam turbine (40) which is connected to an outlet of the solar collector steam superheater unit (4) via a steam conduit system (13), an intermediate storage (20) which is connected to the steam conduit system (13) in a first high-temperature storage connecting point (HA1) interposed between the solar collector steam superheater unit (4) and the steam turbine, a steam cooling device (15), interposed between the high-temperature storage connecting point (HA1) and the steam turbine (40) in the steam conduit system (13), optionally a second high-temperature storage connecting point (HA2) interposed between the first high-temperature storage connecting point (HA1) and the steam turbine (40), and a control device (19, 21). Said control device is designed to control the temperature (TE) to a turbine live steam temperature by first superheating the steam to a steam superheater final temperature (TD) which is above the turbine live steam temperature and then cooling it down to the turbine live steam temperature by means of the steam cooling device (15). In the storage mode, a part of the superheated steam is guided to the intermediate storage (20) in the first high-temperature storage connecting point (HA1) and in an extraction mode, superheated steam is fed from the intermediate storage (20) to the steam conduit system (13) in the first high-temperature storage connecting point (HA1) and/or the second high-temperature storage connecting point (HA2).
