1. A method for increasing the net electric power of solar thermal power plants comprising a plurality of ancillary service pumps (4, 9) characterised in that it uses solar collectors in a more efficient manner, generating additional steam to drive the ancillary service pumps (4, 9) by means of steam turbines (15, 16) using to that end thermal energy which cannot be harnessed in generating electricity due to the solar radiation being greater than the designed radiation of the plant and the plant is already producing its maximum electric power. 2. The method for increasing the net electric power of solar thermal power plants according to claim 1, characterised in that the thermo fluid pumps (4) are driven by means of steam turbines (15). 3. The method for increasing the net electric power of solar thermal power plants according to claim 1, characterised in that the water supply pumps (9) supplying water to the steam generator are driven by means of steam turbines (16). 4. The method for increasing the net electric power of solar thermal power plants according to claim 1, characterised in that the water supply pumps (9) supplying water to the steam generator and the thermo fluid pumps (4) are driven by means of steam turbines (16, 15).
