新疆的煤炭、太阳能、风能储量均居全国前列,更难得的是,新疆与中东部地区在用电时间上形成互补,这独特的优势让"疆电外送"成为可能。 党的十八大以来,"疆电外送"规模不断扩大,如今的新疆电力已织就"内供七环网、外送五通道"的电网格局。这条"电力丝路",不仅点亮了中东部千万家庭 的灯火,更为全国能源的结构转型注入新疆动力。 疆电外送:跨越千里的"电力丝路" 电力工人操控的无人机正在为新疆准东送安徽皖南±1100千伏特高压输电线路进行"空中体检",确保这条跨越3000多公里的电力高速路稳定安全运行。 新疆送变电公司东疆运检分公司副班长郭靖:相比以前我们拿着望远镜走路巡视,无人机巡检的优点是不受山区等环境的影响限制,巡视效率也比人工巡视 快很多,同时它搭载的红外热成像仪和激光雷达等新设备,可以实现全方位、无死角的巡视作业。 为何在电力巡检工作人员眼中,保障输电大通道的稳定运行容不得半点差池?因为每时每刻他们都在保障一场独特的"迁徙"——电力大转场。 新疆与中东部省份存在两三个小时的时差,而这顺理成章形成了天然的发电错峰优势。 清晨8时,北京的街头已车水马龙,迎来一天中的用电早高峰。就在这时,新疆的天空却刚泛起鱼肚白,新 ...

Core Viewpoint - Xinjiang has become a crucial part of China's energy strategy due to its abundant energy resources, including coal, solar, and wind power, which are among the highest in the country. The region's energy development has significantly contributed to the national energy structure transformation since the launch of the "Xinjiang Power Transmission" initiative in 2010 [1][2]. Energy Resources - Xinjiang has confirmed coal reserves of 4.5 trillion tons, accounting for 25% of the national total and approximately 40% of the predicted total coal resources. Solar energy resources are about 4.2 billion kilowatts, representing 26.9% of the national total, while wind energy resources are around 1 billion kilowatts, making up 18% of the national total [1]. - The region's energy resources are likened to "rich mines," providing strong support for energy development [1]. Power Transmission Infrastructure - Since the initiation of "Xinjiang Power Transmission" in 2010, Xinjiang has established five power transmission channels, increasing the number of provinces receiving electricity from 7 to 22, with a cumulative power transmission exceeding 940 billion kilowatt-hours [1][4]. - The first significant project, the Hami-Dunhuang 750 kV transmission line, was completed in 2010, marking the start of Xinjiang's integration with the national grid. The Hami-South Zhengzhou ±800 kV UHVDC project, operational since 2014, has consistently delivered over 40 billion kilowatt-hours annually for six years [3][4]. Technological Advancements - The construction of the world's highest voltage and largest capacity UHVDC project, the Zhundong-Wannan ±1100 kV, was completed in 2019, overcoming numerous global challenges and setting new standards in equipment technology [3]. - New technologies, including drones and digital twins, have been applied to enhance operational efficiency in power transmission stations, tripling the efficiency of maintenance work [3]. Energy Transmission Capacity - By the end of 2024, Xinjiang's power transmission capacity is expected to reach 1,267 billion kilowatt-hours, leading the northwest region. The ongoing construction of the Xinjiang (Southern) Power Transmission to Sichuan and Chongqing project will significantly enhance the power transmission capacity from Southern Xinjiang [4][7]. Energy Grid Development - Xinjiang has built 32 750 kV substations and 98 transmission lines, totaling 12,300 kilometers, making it the province with the most extensive 750 kV grid in China. This development has improved the reliability and capacity of power supply across the region [7]. - The region's energy grid has formed five 750 kV ring networks, enhancing the overall power supply capability and reliability [6][7]. Renewable Energy Integration - As of mid-2023, Xinjiang's total installed power capacity reached 219 million kilowatts, with renewable energy accounting for 128 million kilowatts, representing 58.45% of the total. The region has seen a 6.57% year-on-year increase in cumulative power transmission [11]. - The integration of innovative storage technologies has significantly improved the utilization rate of renewable energy, with the establishment of several large-scale energy storage projects [10][11]. Economic Impact - The "Xinjiang Power Transmission" initiative has not only supported national energy supply but also injected strong momentum into Xinjiang's economic and social development, driving investments in wind, solar, and coal power industries [12]. - The establishment of specialized industrial parks in energy-rich areas aims to create an integrated layout of "power, grid, production, and chain," reducing initial investment burdens for enterprises [13].
