The Crescent Dunes Solar Thermal power station can generate electricity 24 hours a day, with its solar tower, solar collectors and thermal storage.
In February 2016 it successfully generated electricity at its full 110 MW capacity. Now it is supplying power for Nevada on demand, day or night.
Many mirrors all redirect sunlight onto molten salt in the central heating tower. The salt is heated to 1,050°F and this hot molten salt can then be stored. When electricity is needed, the heat can be used to boil water to drive turbines and generate electricity. The molten salt cools to 500 degrees F while heating water and is then reheated in the heating tower.The plant is expected to generate about 500,000 MWh per year of emission-free electricity, enough to meet the needs of about 75,000 households. It will cut 290,000 metric tons of CO2 emissions annually.
