On April 23, China News published that the new energy supply system with "infinite beauty" in the Qaidam Basin is taking shape. CGN New Energy Holdings Co., Ltd (hereinafter referred to as CGN New Energy) Delingha Branch has contributed to the local ecological environment improvement and green and low-carbon value creation. CGN New Energy Delingha Solar Thermal Demonstration Power Station, China's first commercial solar thermal demonstration power station, has so far set a record of 230 consecutive days of stable operation, the article said. In the first quarter of this year, power generation increased by more than 3 million KWH compared with the same period last year, and natural gas use decreased by more than 500,000 cubic meters.

The details are as follows:
According to statistics, Haixi Prefecture, which is located in Qaidam Basin, has more than 100,000 square kilometers of unused land that can be developed for solar and wind power. With abundant solar and wind energy resources, the annual sunshine hours are more than 3,500 hours, and the total annual solar radiation reaches 6,618.3 to 7,356.9 megajoules per square meter, ranking second only to Tibet in China. With an average annual wind speed of more than 3 m/s, an average annual wind power density of 50 to 100 watts per square meter, and an annual wind energy available time of 3,500 to 5,000 hours, it is one of the most ideal areas for the development of wind power industry in China.
CGN New Energy Delingha Solar Thermal Demonstration Power Station, China's first commercial solar thermal demonstration power station, covers an area of 2.46 square kilometers, equivalent to more than 360 standard football fields on the land, 50MW solar thermal project row by row of huge tank type collection, track the rotation of the sun at any time, and collect the heat continuously.
"The power station consists of four major parts: a solar island, a heat transfer and steam generation system, a heat storage island, and a power island. Using the trough heat conduction oil heat collection technology route, supporting 9 hours of molten salt heat storage, can achieve 24 hours of continuous and stable power." Liu Yiding, general manager of CGN Delingha Solar Energy Co., Ltd, said that so far, the plant has set a historical record of 230 consecutive days of stable operation. In the first quarter of this year, power increased by more than 3 million KWH compared with the same period last year, and natural gas use decreased by more than 500,000 cubic meters.
CGN's Delingha 2 million-kilowatt integrated solar thermal storage project, which is currently under construction, will generate 3.6 billion KWH of electricity annually by the end of 2024, equivalent to the annual electricity consumption of 1.15 million households, Yiding Liu said. After the project is completed and put into operation, it can save 1.1 million tons of standard coal and reduce 2.6 million tons of carbon dioxide emissions every year, which has significant benefits for regional ecological environment improvement and green and low-carbon value creation.
