The Gemasolar Concentrated Solar Power Plant in Spain began operation in 2011.
It can generate electricity 24 hours a day. The solar collectors direct sunlight onto a single solar tower, heating molten salt. This heat can be stored and used as required to drive a steam turbine and generate electricity. It can run for up to 15 hours without any sunlight.
In 2013 Gemasolar set a solar energy record by producing energy 24 hours a day for 36 days straight.
The 19.9 MW plant is capable of producing more than 110 GWh per year.
