One of China's First Batch of CSP Demonstration Projects
The First Molten Salt Tower CSP Plant in China that Has Exceeded Its Designed Production
One of China's first batch of CSP Demonstration Projects, entitled as National Strategic and Emerging Industry Key Project by NDRC (Chinese National Development and Reform Commission).
Located in Delingha, Qinghai Province, is a molten salt tower CSP plant configured with 27,135 sets of 20m² heliostat. The designed electricity output is 146 GWh/year, which meets power demand of 80,000 households, saves 46,000 tons standard coal and reduces 121,000 tons CO₂ emission every year.
The plant started construction in Mar. 2017, was synchronized to the grid on Dec. 30, 2018 and reached full-load operation on Apr. 17, 2019.
After the Plant was put into operation in July 2019, through continuous optimization of operation strategy, its performance steadily improved and repeatedly broke records in terms of non-stop operation hours, daily, monthly, and annual performance. The total annual accumulative actual power generation of the Plant in 2022 was 146.4 GWh, becoming the world's first CT CSP plant. By the end of 2024, the plant has achieved the power generation target for three consecutive years, becoming a model for the construction and operation of CSP plants both at home and abroad.
Delingha 50MW Molten Salt Tower CSP Plant has passed complete technical assessment of Fichtner, a German independent engineering consultancy company. In the assessment report, Fichtner considers the design of the plant corresponds to state-of-the-art design of similar plants in the world, the self-developed heliostat and control system and other core equipment are of high quality, and the plant has good operation performance and advanced quality with the level of other international peers.
