Suppliers
The mirrors were delivered by Abengoa, the solar receiver was designed and built by , and the Solar Tower was designed and built by ALTAC, both Spanish engineering and construction companies.Specifications
Each of the mirrors has a surface measuring that concentrates the sun's rays to the top of a 115-meter (377 ft) high, 40-story tower where a solar receiver and a steam turbine are located. The turbine drives a generator, producing electricity. The PS10 is located 20 km west of Seville (which receives at least nine hours of sunshine 320 days per year, with 15 hours per day in mid summer). The solar receiver at the top of the tower produces saturated steam at 275 °C. Theenergy conversion efficiency
Energy conversion efficiency (''η'') is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radia ...

and 285 °C. The water evaporates and flashes back to steam, releasing energy and reducing the pressure. Storage is for 30 minutes. It is suggested that longer storage is possible, but that has not been proven in an existing power plant. However, there are many considerations for using molten salt as an energy storage
Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production.
A device that stores energy is generally called an accumulator or battery.
