Abengoa Moves Forward with Large-Scale Solar CSP

LCG, December 19, 2012--Abengoa announced last Friday the inauguration of the 100-MW, Castilla-La Mancha Solar Complex in Spain. The project employs a concentrating solar power (CSP) design.

The Castilla-La Mancha Solar Complex is comprised of two, 50-MW parabolic trough plants. The trough collectors track the movement of the sun across the sky and focus solar energy onto a tube circulating a synthetic heat transfer oil. The oil is heated to approximately 400 degrees C (752 F) and used to generate superheated, high pressure steam that is delivered to a steam turbine to drive an electrical generator, which creates electricity.

In the summer of 2013, Abengoa is also scheduled to commence operations of a larger solar CSP project in Arizona, about 70 miles southwest of Phoenix. The Solana project is designed with a generating capacity of 280 MW. The design also provides for six hours of molten salt thermal energy storage to allow energy to be dispatched as needed, even given cloudy periods and after sunset, when customer summer peak demands for air conditioning can occur. Construction began two years ago, and the project is now over 80 percent complete.
