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.

Solana – Abengoa

The Solana Generating Station is a 280-megawatt (MW) utility-scale solar thermal electric power plant being built by Abengoa about 70 miles southwest of Phoenix near Gila Bend, Arizona. Solana will couple CSP technology with the ability to store energy during non-sunlight hours to better meet Arizona residents’ peak demand.
