Gemasolar Thermosolar Plant
Youtube text: A unique thermosolar power station in southern Spain can shrug off cloudy days: energy stored when the sun shines lets it produce electricity even during the night. The Gemasolar station, up and running since last May, stands out in the plains of Andalusia.
Tower 140 m high, power 19.9 MW, uses molten salt as heat transfer and storage medium. 2650 heliostats, each 120 m2. Gemasolar is the first commercial solar plant with central tower receiver and molten salt heat storage technology. Due to its storage system it allows to produce electricity for 15 hours without sunlight (at night or on cloudy days).
