"The stone roads in Dabancheng are hard and flat, and the watermelon is big and sweet..." A folk song made Dabancheng a household name many years ago. Today, this small northwestern city has gained the reputation of "China's Wind Valley".   "It is optimistic about Dabancheng scenery resource enrichment, Huadian North Xinjiang Urumqi 1 million kilowatt scenery base built here this year." Shi Xiaoliang, deputy general manager of Xinjiang Huadian Weihuliang New Energy Co., LTD., introduced that the base is the first batch of "Shage famine" large-scale wind power base projects in the country, and the technical and economic indicators have reached the domestic leading level after the project was put into operation. Deserts, Gobi and deserts have long been seen as the disadvantages of Xinjiang's natural endowments, but modern technology has changed that perception. Today, it is an advantageous area for the construction of scenic bases. By the end of October this year, Xinjiang's installed capacity of wind power, photovoltaic and other new energy exceeded 84 million kilowatts, accounting for more than half of Xinjiang's total installed capacity of electricity, and Xinjiang's installed capacity of new energy has ranked first in the country.   Facing the "tuyere" of development, Xinjiang's new energy industry is moving rapidly toward scale and intensification.   "At present, Xinjiang has built three new energy bases of 10 million kilowatts in Hami, eastern Jungdong and Tarim in southern Xinjiang." Zheng Ziwen, deputy director of the New energy and renewable Energy Department of the Development and Reform Commission of Xinjiang Uygur Autonomous Region, introduced that Xinjiang is also accelerating the construction of Hami North, Ruoqiang and other ten-kilowatt new energy bases.Feeding, heating, pulling rods... In the production workshop of Hami Clean Silicon Industry, the first high-efficiency N-type large-size monocrystal silicon project in Xinjiang, the polysilicon material is transformed into a 3.8 meter long monocrystal silicon rod weighing about 400 kg after multiple processes in a high-temperature single crystal furnace of more than 1400 degrees Celsius. Qingdian Silicon technology research and development Department senior manager Qin Xiandong introduced that the project was fully completed in June this year, and the products will be mainly used for photovoltaic manufacturing industry. "The estimated resources of raw quartzite in Hami City are 34.35 million tons, and the development prospects of silicon-based industry are broad." Dou Rencai, deputy director of the Hami City Industry and Information Technology Bureau, said that regional resources, policies and other advantages will be given full play to promote the integrated development of new material industries such as silicon photovoltaic and new energy green electricity.Photovoltaic modules, fans, blades, towers... Xinjiang's new energy equipment manufacturing industry has continuously enriched its product categories and accelerated the improvement of its industrial chain. Data from the Autonomous region's Department of Industry and Information Technology show that in the first 10 months of this year, the output of major products in Xinjiang's silicon photovoltaic industry chain grew rapidly, and the output of industrial silicon, polysilicon and monocrystalline silicon increased by 40%, 21.2% and 27%, respectively. Energy equipment industry chain market demand is strong, the output of wind turbines, transformers and other products increased by 30.2% and 15.4%, respectively.   In the vast land of Xinjiang, the white windmill "forest" and the row of blue photovoltaic "ocean" are becoming common scenery.

The Kubuqi Desert, China's seventh largest desert, is located in the "J-shaped Bend" of the Yellow River, an area that was once known as the "Sea of Death" and posed a threat to the ecological security of the "J-shaped Bend" of the Yellow River. Thanks to the efforts of the local people, over 6,000 square kilometers of the desert have been covered with greenery. The efforts to restore the desert continue. In the past two years, a "Solar Power Great Wall" for desert control has been laid out in the area, combining points, lines and surfaces, to promote the governance of China's seventh largest desert and prevent the invasion of shifting sands into the "J-shaped Bend" of the Yellow River. This "Solar Power Great Wall" for desert control integrates three functions: solar power generation, ecological restoration, and income increase, exploring the path of green and low-carbon development and jointly building a beautiful and clean world, providing a "Chinese solution" for global desertification control.   In Chaideng Gacha, Zhaojun Town, Dalate Banner, Ordos City, 3.46 million blue photovoltaic panels rise and fall with the undulating Kubuqi Desert, like waves in the vast sea of sand, forming a "sea" of 45,000 mu of photovoltaic panels. Since 2017, a 50,000-mu, 1 million-kilowatt national third batch photovoltaic application leading base has been completed in the heart of the Kubuqi Desert, achieving full capacity grid connection and power generation. Not only this 1 million-kilowatt photovoltaic base, but also throughout the northern edge of the Kubuqi Desert, large and small photovoltaic bases are being connected to form a line, and a spectacular "Solar Power Great Wall" for desert control is rising in the sand sea.   According to Li Tianyun, deputy director of the Forestry and Grassland Bureau of Ordos City, the "Solar Power Great Wall" for desert control in the Kubuqi Desert is a descriptive concept, an image metaphor for the relatively concentrated, intermittent and linear layout of major national new energy photovoltaic projects that have been completed, are under construction, or are planned in the northern edge of the Kubuqi Desert. "The 'Solar Power Great Wall' for desert control built in the northern edge of the Kubuqi Desert and south of the Yellow River is a continuation of photovoltaic projects on the bare sand of the Kubuqi Desert. After full completion, the area of photovoltaic desert control will exceed 2 million mu. Currently, the city has built a total of 5.42 million kilowatts of photovoltaic projects and over 200,000 mu of photovoltaic desert control area."   Previously, the main application scenarios of photovoltaic power generation in China were ground-mounted photovoltaic, water-mounted photovoltaic, and rooftop photovoltaic. What are the advantages of building a "Solar Power Great Wall" for desert control in the desert? Xu Ming, the president of the International Industrial Ecology Society, said that using photovoltaic power generation for desert control is an innovative solution with great potential. Take the Kubuqi Desert as an example. On the one hand, there are abundant land resources here, providing sufficient space for the layout of photovoltaic facilities and the implementation of related desert control projects. On the other hand, the average annual sunshine duration here is 3,100 hours, with rich solar energy resources, which helps ensure the efficiency and output of photovoltaic power generation. In addition, Ordos City has built two ultra-high voltage power transmission channels, namely the Mengxi to Tianjin South and Shanghaimiao to Shandong, and is accelerating the construction of two more power transmission channels, ensuring the availability of power transmission channels.   Entering the Jiaao Photovoltaic Industry Chain Low-carbon Demonstration Base project site in Ordos City, cranes are everywhere, and factories and office buildings are rising from the ground. This project with a total investment of 28 billion yuan is being accelerated. "The project is planned to be completed and put into production by the end of 2025. By then, it will form a vertically integrated production base covering silicon ingot, silicon wafers, batteries and modules in the photovoltaic industry," said Huang Bowei, director of the Development and Reform Commission of Ordos City.   Huang Bowei introduced that during the process of building the "photovoltaic Great Wall" for sand control, Ordos City has coordinated the development of the photovoltaic industry and equipment manufacturing, attracted photovoltaic module and other production enterprises to set up factories, and created a new energy equipment manufacturing industrial cluster to boost high-quality economic development.
