总里程已突破5万公里！“十四五”期间我国特高压工程加快建设

Core Viewpoint - The "Ningdian into Hunan" project is a key initiative in China's 14th Five-Year Plan for power development, accelerating the construction of UHV projects and promoting green energy development in the country [1][5]. Group 1: UHV Project Development - Since the beginning of the 14th Five-Year Plan, significant UHV projects such as "Longdian into Shandong" and "Xinjiang into Chongqing" have been put into operation, with the "Ningdian into Hunan" project recently commencing power transmission [1]. - The State Grid has completed and put into operation over 41 UHV projects, with a total transmission capacity exceeding 350 million kilowatts, representing a 30% increase from 270 million kilowatts at the end of the 13th Five-Year Plan [1][3]. Group 2: Investment and Infrastructure - During the 14th Five-Year Plan period, total investment in UHV projects in China has exceeded 380 billion yuan, with 19 UHV projects under construction [5]. - The total length of UHV projects in China has surpassed 50,000 kilometers, equivalent to more than one lap around the Earth's equator [5]. Group 3: Clean Energy Integration - A notable trend in China's UHV construction is the establishment of UHV projects originating from clean energy bases in regions such as Southwest and Shale Gas areas, with over 60% of UHV projects connected to clean energy sources [3]. - The scale of renewable energy connected to operational UHV projects has exceeded 1.3 billion kilowatts [3].
