Noor III is the newest stage of the Ouarzazate Solar Power Station in Ouarzazate, Morocco. This site utilizes a concentrated solar power (CSP) tower design with 7,400 heliostat mirrors that focus the sun’s thermal energy toward the top of a 820-foot-high (250 meters) tower at its center. At the top of the tower, there is molten salt, which is used in this process due to its ability to get very hot (500–1022°F / 260–550°C). The molten salt then circulates from the tower to a storage tank, where it is used to produce steam and generate electricity. The Noor III CSP tower can produce and then store enough energy to provide continuous power to the surrounding area for ten days.
