Abengoa to build a 110 MW solar thermal plant in Chile

CSP Today reports that Spanish developer Abengoa will build a 110 MW solar thermal power plant in Chile with 17.5 hours of storage - Abengoa wins first CSP tender in Chile, will build a 110 MW tower plant to generate around the clock.

The plant will be a 110 MW tower type with molten salts as working fluid and energy storage medium, this will be the first commercial project for Abengoa with the molten salt technology for tower plants. With the design provided by the Spanish company, the plant will be able to generate electricity for up to 17.5 hours without solar radiation, only with the heat stored in the molten salt tanks.

The project will be located in the Atacama Desert, the region with the highest solar radiation concentrations in the world. It will be the first solar-thermal plant for direct electricity production in South America.

Solar-thermal tower technology uses a series of mirrors (heliostats) that track the sun on two axes, concentrating the solar radiation on a receiver on the upper part of the tower where the heat is transferred to the molten salts. The salts then transfer their heat in a heat exchanger to a water current to generate superheated and reheated steam, which feeds a turbine capable of generating around 110 MW of power.
