Its activities include the promotion, introduction and improvement of renewable energies on the energy market, as well as promotion of technology transfer, training and scientific outreach. With 1342 employees, 56% graduated, CIEMAT has a wide presence in both national and international scientific and technical forums. In addition to the head offices and laboratories located in Madrid, CIEMAT owns several research centers located in other Spanish provinces. The Plataforma Solar de Almería, PSA (, which is one of these outlying centers of the CIEMAT, is formally considered by the European Commission as an European Large Scientific Installation and it is also the largest and most complete R+D center in the World devoted to solar thermal concentrating systems. PSA is also a Singular Science and Technology Infrastructures (ICTS) of Spain. The good solar conditions, its diverse solar facilities and the highly-skilled PSA staff, provide a unique infrastructure for R+D, evaluation, demonstration and technology transfer regarding solar energy applications. PSA is located in southeastern Spain, in the Tabernas Desert at 37º05’27.8” north and 2º21’19” west. It receives a direct annual insolation of more than 1900 kWh/(m2·year) and the average annual temperature is around 17ºC. PSA is integrated in the CIEMAT organization as an R&D division of the Department of Energy. PSA counts with over 30 years of experience in the operation, maintenance and evaluation of solar thermal concentrating systems, their components and different types of commercial applications. At present, PSA has a large variety of experimental installations and laboratories for R+D activities related to solar thermal concentrating systems to both power and solar water treatment applications.
