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.
