Method for the natural-draught cooling of a high-concentration thermoelectric solar plant that includes a central receiver or tower with a heliostat field, wherein the tower is used as a natural-draught cooling tower. The steam originating from the turbine will be made to circulate through a series of condensers located at the base of the tower, where said condensers condense the steam therein and discharge the condensation heat to the atmosphere. The fluid responsible for this heat exchange is the air at ambient temperature at the base of the tower. Once condensed, the steam is pumped back towards the receiver so that it can be re-used as a heat-transfer fluid. The cooling air travels up through the tower and exits through the highest part thereof. The plant can be used to reduce not only its own electricity consumption, but also water consumption.

In a startup period for a solar thermal electricity generating system, a non-solar source of steam heats a downstream receiver (for example, a superheating receiver) prior to insolation being available. Insolation, once available, heats an upstream receiver (for example, an evaporator). The upstream receiver can be arranged in a recirculation loop with a steam separation drum, which may be bypassed during the initial heating of the upstream receiver by insolation. Once sufficient temperature and pressure have been reached, steam from the upstream receiver is directed to the downstream receiver by way of the steam separation drum to replace the non-solar source of steam. Heating of the downstream receiver using steam from the upstream receiver continues until a threshold temperature and pressure are reached. Insolation is then directed at both the upstream and downstream receivers to generate steam for electricity production by a turbine. 1.
