Parabolic trough power plant Andasol III

The 50 MW solar thermal power plant Andasol III is based on the Eurotrough design. The plant is situated in close vicinity to the power plants Andasol 2 and 3. The collector field covers an area of approximately 1,300 m x 1,500 m and consists of 152 loops respectively 7,296 solar collector elements (SCEs). The thermal storage allows an operation of the plant with nominal output for 7.5 hours after sunset.
The power plant produces approximately 179 GWh annually, providing up to 200,000 people with electricity.

Parabolic Troughs

Proven state of the art for CSP

Over the years, sbp sonne developed and licensed three different types of parabolic trough collectors: the EuroTrough, the HelioTrough and the UltimateTrough. We are now focusing on the distribution and commercialization of the ‘HelioTrough’ and ‘UltimateTrough’, as these collector developments have been proven to significantly reduce costs and improve performance for large scale power plants.

The UltimateTrough collector for Concentrating Solar Power (CSP) plants is the world’s largest and most advanced parabolic trough collector. Measurements indicate that efficiency of the UltimateTrough is over 10% higher as compared to the benchmark collector.
