At 1:26 on June 18, 2021, the Hami CSP 50 MW molten salt tower solar thermal power generation project invested and constructed by China Energy Construction realizes stable grid-connected power generation without light at night, and uses solar energy storage during the day when there is no light at night. The realization of thermal energy collection and power generation marks the Hami CSP project officially opened the "24-hour uninterrupted power generation" mode.

The Hami CSP project is a national demonstration CSP project, invested and constructed by China Energy Construction Investment Corporation, general contracted by the Northwest Institute, Anhui Power Construction No. 1 Company, Anhui Power Construction No. 2 Company, Jiangsu Power Construction No. 1 Company, Tianjin Power Construction, Northwest Power Construction Contracted construction, supervised by the Central South Institute, commissioned, operated and maintained by the Science and Technology Development Company. In the process of project construction, China Energy Construction Investment Corporation led all parties involved in the construction to overcome the adverse factors such as high temperature, scorching heat, wind and sand, severe cold, and new crown epidemic, and set up a domestic technical team, set up a localized technology research team, and actively promoted localized debugging The plan breaks through the technical bottleneck, overcomes the problems of molten salt pipelines and heat absorber condensation, and finally realizes the use of daytime heat storage and grid-connected power generation under night and no light conditions.

The Hami CSP project integrates power generation and energy storage. It is a green power source that can replace fossil energy power stations as basic load and peak load. It plays an important role in ensuring the safe, stable and efficient operation of the power system. After the project is fully put into operation, it can provide clean, stable and adjustable high-quality electricity to the grid with about 198.3 million kilowatt-hours each year, and save 61,900 tons of standard coal, which will help achieve the carbon peak and carbon neutral "30·60 target". Significance.
