Kumul Dongfang Tower Stellio

Hami/Kumul, China, 2021

The project is part of the first batch of Concentrated Solar Power demonstration projects in China. For the first time, the Stellio heliostat developed by sbp sonne is used here.
The planning of the entire solar field is being carried out in cooperation with our Spanish partners. The steel structure, mirrors, electrical system, and part of the control technology are supplied by local companies.
For the assembly of the 14,500 heliostats, a semi-automatic assembly line, developed by our Spanish partner and leased to the client, is installed, and operated on the construction site.
As this project marks the first commercial use of the new heliostat, it presents special challenges. Our tasks include the coordination of all companies involved as well as quality assurance of the used components and the assembly. On top of this, there are difficult working conditions with winter temperatures of below -20 °C.
