Concentrating Solar Power (CSP) is a type of Renewable Energy that uses the sun's energy to generate electricity and process heat. Most applications are large-scale. Solar Thermal Power Plants are large scale renewable energy infrastructures using heat produced by contracted solar beams (Concentrated Solar Power (CSP)). Mirrors concentrate solar beam on a receiver. The produced heat with temperatures of 400ºC to 1000ºC can be used directly, be transformed into electricity or stored.
