架起空中"能源丝路"--来自新疆的调查

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 launch of "Xinjiang Power Transmission," five external transmission channels have been established, increasing the number of provinces receiving electricity from 7 to 22, with a cumulative transmission of over 940 billion kilowatt-hours [1][4]. - The "Hami-Dunhuang 750 kV" project marked the beginning of Xinjiang's connection to the national grid in 2010, followed by the "Hami South-Zhengzhou ±800 kV" project in 2014, which has consistently delivered over 40 billion kilowatt-hours annually for six years [3][4]. Technological Advancements - The "Zhundong-Wannan ±1100 kV" project, operational since September 2019, is the highest voltage and largest capacity transmission project globally, overcoming numerous technical challenges [3]. - New technologies, including drones and digital twins, have been applied to enhance operational efficiency by three times since the project's launch [3]. Energy Development Goals - By the end of 2024, Xinjiang aims to achieve an external transmission capacity of 1,267 billion kilowatt-hours, leading the northwest region [4]. - Plans for 2025 include the construction of 41 new and ongoing ultra-high voltage projects, marking a 50% increase from 2024 [7]. Renewable Energy Integration - As of mid-2023, Xinjiang's total installed capacity reached 219 million kilowatts, with renewable energy accounting for 58.45% of this capacity [11]. - The region has seen a significant increase in green electricity transactions, with 61.5 billion kilowatt-hours traded in the first half of 2023, a 13.57% increase from the previous year [11]. Economic Impact - The "Xinjiang Power Transmission" initiative is expected to inject significant momentum into local economic development, particularly in the wind, solar, and coal industries [12]. - The establishment of specialized industrial parks in energy-rich areas aims to create an integrated layout of "electricity, grid, production, and chain," reducing initial investment burdens for enterprises [13].
