Gemasolar – Torresol

Gemasolar is the first commercial-scale plant in the world to apply central tower receiver and molten salt heat storage technology. The relevance of this plant lies in its technological uniqueness, since it opens up the way for new thermosolar electrical generation technology. The prolongation of the plant’s operating time in the absence of solar radiation and the improvement in efficiency of the use of the heat from the sun makes Gemasolar’s output much higher than that which is delivered by other technologies in a facility with the same power.

Project Overview

  • Rated electrical power: 19.9 MW.
  • Net electrical production expected: 110 GWh/year.
  • Solar field: 2,650 heliostats on 185 hectares.
  • Heat storage system: the molten salt storage tank permits independent electrical generation for up to 15 hours without any solar feed.
