Valle 1 and Valle 2 are two adjacent solar thermal power plants using cylinder-parabolic collector technology, with a molten salt thermal storage system, located in the municipality of San José del Valle (Cádiz), Ctra A-389, p.k. 11,250. Each of them has a solar field of 510,000 m2 housing 150 loops or cylinder-parabolic collectors, with a surface area of 510,120 m2. Valle 1 and Valle 2 each produce electricity for 7.5 hours in the absence of solar radiation, with a capacity of 50 MW, capable of supplying 160 GWh per year. The heat collected by the salts, which can reach temperatures of over 393ºC, is used to generate steam, which is used to produce electricity. The plant’s thermal system will be completed with an auxiliary liquefied natural gas combustion installation, with a thermal power of 30 MWt. Together they will reduce CO2 emissions by more than 90,000 tonnes per year.
