1. Power generation plant including a solar radiation receiver for heating a medium stream and a turbine assembly having an inlet arranged to receive said medium stream from an outlet of the solar radiation receiver when heated thereby, said turbine assembly being coupled to an electric power generator, wherein:
a combustor is positioned downstream of the solar radiation receiver and upstream of the turbine assembly, said combustor being connected in series with the solar radiation receiver so as to receive said medium stream; an air compressor unit having a compressed air outlet is arranged to supply compressed combustion air to the combustor; and a steam generator is arranged to extract heat from an outlet flow of said medium stream from the turbine assembly, and to produce steam to be transmitted to a medium stream inlet of the solar radiation receiver and subsequently to the combustor, wherein a condenser is arranged downstream of the steam generator, wherein means are arranged to transfer liquid water obtained by the condenser to the steam generator and/or to the solar radiation receiver, and wherein an auxiliary turbine unit is arranged in said medium stream downstream of the solar radiation receiver and upstream of said turbine assembly, said auxiliary turbine unit being coupled to an auxiliary power consumer.
