Recently, Northwest Engineering Corporation Limited (POWERCHINA NORTHWEST) announced that the 200MW solar tower CSP project officially started the construction in Delingha that is undertaken by POWERCHINA NORTHWEST as a EPC contractor and invested by CGN New Energy.
CGN New Energy’s Delingha solar hybrid project has a total capacity of 2000MW with a planned area of about 53,000 mu (3529.8 million square meters) , which will be constructed in two phases and each phase consists of 800 MW of PV and 200MW CSP. At present, it’s the CSP part of the first phase of the project that started the construction, which is also the world's largest solar tower CSP project in single-unit capacity under construction.
The project adopts the hybrid form of photovoltaic and molten salt solar thermal power generation, using the heat from solar field and the residual electricity of curtailment wind and solar power in the area to heat the molten salt in the thermal energy storage tank , and then generate high-temperature steam through the salt-water heat exchanger to drive the steam turbine generator to generate electricity. 
The total design annual utilization hours of this 200MW CSP plant is 1,319 hours, an annual power generation of 263.88 million kWh. After the whole project is completed and put into operation, the annual on-grid electricity can reach 3.65 billion kWh. Mr. Ke Xijun, the person in charge of the project introduced, The project will be built into the first new energy hybrid demonstration project in the western part of the Haixi region with a molten salt CSP plant as the peak shaving power supply, helping the construction of a national clean energy industry highland in Qinghai Province and contributing to the achievement of the carbon neutral goal. 
CGN New Energy and POWERCHINA Renewable Energy have a 50MW parabolic trough and a 50MW solar tower plant in operation in Delingha and Gonghe County, Qinghai Province, respectively.
