The three heat absorption towers of the Qinghai Delingha CSP Demonstration (Pilot) Project were capped simultaneously

China News Service, Delingha, Qinghai, October 27 (Reporter Sun Rui) The Propaganda Department of Delingha Municipal Party Committee, Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province reported on the 27th that the three heat absorption towers of Qinghai Zhongkong Solar Power Co., Ltd.’s Delingha 350,000-kilowatt solar thermal power demonstration (pilot) project were capped simultaneously on the 26th. The tower is 199 meters high. It is currently the largest tower solar thermal power generation project in the world in terms of installed capacity and energy storage capacity.

It is reported that the project has an installed capacity of 350,000 kilowatts. It uses tower-type molten salt photothermal power generation technology and is equipped with 14 hours of molten salt energy storage, which can continuously and stably generate electricity for a long time. The construction of the three heat-absorbing towers took five months since the first mold of the main body was poured on June 6.

As one of the first batch of solar thermal power generation demonstration projects of the Qinghai Provincial Energy Bureau, after the project is put into operation, it will promote the large-scale and commercial application of solar thermal power generation technology, optimize the regional energy structure, enhance the peak load regulation capacity of the power grid, and drive the development of industrial chains such as equipment manufacturing and operation and maintenance services. Currently, the main projects such as the main factory building and heat storage and exchange system are progressing simultaneously.

Delingha City is improving the manufacturing chain of photothermal equipment around core links such as collector tubes, reflectors, and molten salt systems. At present, the city has built 42 grid-connected new energy projects, and introduced 10 new energy and photothermal equipment manufacturing projects, including Longteng Delingha 600MW trough collector equipment manufacturing, Asker insulation materials, and Kesheng photothermal equipment manufacturing. After completion, it will have an annual production capacity of 100,000 collector tubes and 4 million square meters of trough reflectors, with an annual output value of approximately 1 billion yuan, filling Qinghai's shortcomings in the supply of photothermal equipment.
