The Andasol solar power station is a 150-megawatt concentrated solar power station and Europe's first commercial plant to use parabolic troughs. Located near Guadix in Andalusia, Spain, the Andasol plant uses tanks of molten salt as thermal energy storage to continue generating electricity, irrespective of whether the sun is shining or not. It consists of three projects, completed in 2008, 2009 and 2011, and occupying a total area of about 200 hectares (490 acres). Because of its high altitude (1,100 m; 3,600 ft) and the semi-arid climate, the site has exceptionally high annual direct insolation. This aerial view of the Andasol plant was taken in 2021, with the snow-capped peaks of the Sierra Nevada in the background.Photograph credit: kallerna
