Local Environmental Conditions

The project located in the province of Qinghai in China, which has abundant solar radiation, but is a high altitude desert environment and the has severe weather conditions.

Lessons Learned

By the end of February 28, 2018, Delingha 10MW power station has been completing 86.7% of the designed power generation. From the statistical analysis, the main factors causing the power generation not fully reaching the capacity include equipment failure, extreme weather effects and operational differences, where the equipment failure is the most important factor. After fixing all the issues, the power generation reached 96.6% of the designed capacity during the 2018.[1]

From Mr. Jianxiang Jin, the biggest economic risk of concentrated solar power project is the power generation does not reach the designed value. Compared to trough-type heliostat power station, the tower-tupe have advantages of heat and light efficiency. SUPCON Solar has master the core technologies of tower type high-precision large-scale CSP. The deviation between the power generation of 10MW power station and the design value is less than 5%, which indicated the technology and equipment can be successfully put into operation and set a good foundation for the following 50MW and 100MW projects.[2]
