According to the news of the vice chairman member of China Solar Thermal Alliance (CSTA), Shouhang Hi-Tech Energy Technology Co., Ltd. (Shouhang Hi-Tech) , Dunhuang Shouhang 100MW solar tower CSP plant set a new highest record in generation in 2023. As of the end of November, 2023, the plant generated 235 GWh, an increase of 21% above the same period of last year. 
Dunhuang Shouhang 100MW solar tower CSP plant is the first  100MW level solar tower plant in China, and independently designed, developed, invested and constructed and maintained by Shouhang Hi-Tech. It was put into operation in 2018, and had the longest continuously operation time of 338.21 hours.
Time milestone
The plant was connected to the grid for the first time on December 28, 2018.
In June 2019, the power station achieved full load operation. The annual generation was 86.4717GWh.
In 2020, the annual power generation was 137GWh, an yearly increase of 58.3%.
In 2021, the annual power generation was 200GWh, an yearly increase of 46.2%.
In 2022, due to turbine defects, industrial experts proposed that the maximum safe operating load of the turbine should not exceed 63%.  The annual power generation was the same as that in 2021.
In 2023, it reached the highest record, and the power generation from Jan. to Nov. was 235GWh, with an yearly increase of 21%.
In 2023, a large amount of light was curtailed because the maximum safe operating load of the turbine cannot exceed 63%, which cause the generation reduction of 65.79GWh. In September 2023, the monthly power generation exceeded 31.92 million kWh, the longest non-stop power generation time was 338.21 hours, and the self-electricity-consumption rate was 8%. The operation indicators of solar collection system, heat storage and heat exchange system other than power generation system have been significantly improved in 2023.
Shouhang high-tech currently has 4 new CSP projects orders on hand, with an installed capacity of 400MW.
