Abstract: 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.
