Pioneers again: China’s first large-scale CSP project starts operation

sbp sonne gmbh is happy and proud to inform that, together with our partners, we are successful again: After having provided solar collector technology for first-of-its-kind concentrating solar power (CSP) plants in Spain (Andasol), Egypt (Kuraymat), India (Godavari) and Kuwait (Shagaya), we are now pioneers in China:

China’s first large-scale commercial CSP project, the CGN Delingha 50 MW parabolic trough CSP plant, has started operation on Oct 10th, 2018. sbp sonne supported China Guangdong Nuclear Power Group (CGN) and SunCan / Beijing Shouhang IHW Resources Saving Technology Co. Ltd. in realizing this milestone project.

The Delingha solar field is based on the proven EuroTrough collector technology. sbp sonne provided the technology on a licensing basis, and especially adapted the design to both Chinese standards and to specific local conditions, such as wind loads, ground slope and low temperatures. Helping to make the project a success, sbp sonne engineers also trained our Chinese partners, enabling them to manufacture, assemble and install high-quality EuroTrough collectors.


The plant is located on a sparsely populated plateau at an altitude of 3,000 meters in the northern Qinghai province in China. Its collector field consists of 190 loops, which equals more than 9000 solar collector elements (SCEs). The SCEs include over 250,000 mirrors with a total area of 620,000 square meters.

Realizing the CGN Delingha 50 MW plant has been a milestone for the Chinese CSP industry, making China the 8th country worldwide with a large-scale CSP plant in operation. Out of a first batch of 20 pilot projects in the country, the Delingha power plant is now the first to be operational, and thus paves the way to a cleaner and more sustainable energy future.
