The Valle Solar Power Station is a 100 megawatt (MW) solar thermal power station in the town of San José del Valle, province of Cádiz, Spain. The power station became operational in January 2012.

The power station consists of two adjacent plants, Valle 1 and Valle 2. Each one has a nameplate capacity of 50 MW, using SENER parabolic trough collectors creating solar fields of 510,120 square metres on a total surface area of 460 hectares.[2] Net electrical output for each section is expected to be 160 gigawatt-hours (GW·h) per year. Each plant will have a molten salt thermal storage system containing 28,500 tons of molten salt (60% sodium nitrate / 40% potassium nitrate),[1] capable of storing enough heat to generate 750 MW(e)·h of electricity — enough to operate at full power for 7.5 hours without sunshine.[3]

The Valle plant is owned by Torresol Energy, a joint venture between SENER (60%) and the Abu Dhabi Future Energy Company (40%). It was built by SENER between December 2009 and December 2011, at a cost of €540 million (US$700 million).
