Ultimate Trough DUBA

The DUBA Green Integrated Solar Combined Cycle Power Plant is going to be built right next to the Red Sea in Saudi Arabia. This integrated solar plant is the first that features the newly developed Ultimate Trough parabolic trough collector.
It is a combined cycle plant (fossil and solar energy) with a total electrical output of 565 MW.
The proportion of solar output is approx. 40 MW electrical.

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.
