Concentrating solar power (CSP), also known as solar thermal electricity, is a commercial technology that produces heat by concentrating solar irradiation. This high-temperature heat is typically stored and subsequently used to generate electricity via a steam turbine (Rankine cycle) 1 .
One of the benefits of CST is that the captured heat can be stored cost-effectively for long periods with little loss of energy. This means that CST can be used to generate electricity or provide heat when the sun isn''t shining. Globally, most CST plants used for electricity production incorporate 3-15 hours of thermal energy storage.

Where temperatures below about 95 °C are sufficient, as for space heating, flat-plate collectors of the nonconcentrating type are generally used. Because of the relatively high heat losses through the glazing, flat plate collectors will not reach temperatures much above 200 °C even when the heat transfer fluid is stagnant. Such temperatures are too low for efficient conversion to electricity.
