Core Insights - The construction of the Tibet-Guangdong DC transmission project has commenced, marking it as the world's most powerful, advanced, and largest flexible DC transmission project [1] Group 1: Project Overview - The Tibet-Guangdong DC transmission line spans approximately 2,681 kilometers, crossing four provinces: Tibet, Yunnan, Guangxi, and Guangdong [1] - The project has a rated transmission capacity of 10 million kilowatts [1] Group 2: Environmental Impact - Upon full operation in 2029, the project is expected to deliver over 43 billion kilowatt-hours of electricity annually to the Greater Bay Area, which is about half of the annual output of the Three Gorges Dam [1] - The project will utilize 100% clean energy, replacing approximately 12 million tons of standard coal consumption and reducing carbon dioxide emissions by about 33 million tons [1] Group 3: Economic Implications - The total investment for the project is approximately 53.2 billion yuan, with an additional investment of over 150 billion yuan for supporting "water-wind-solar integrated" power bases [1] - The project is anticipated to significantly boost the growth of related upstream and downstream equipment and construction industries, with peak employment expected to exceed 100,000 jobs [1]

9月16日，我国"十四五"规划建设的跨省区输电重点工程——藏粤直流输电工程建设启动，这是目前世 界上输电能力最强、技术水平最先进、投资规模最大的柔性直流输电工程。 藏粤直流工程输电线路全长约2681公里，自西向东跨越西藏、云南、广西、广东4省区，额定输电容量 1000万千瓦。该工程2029年全面投运后，藏东南清洁能源基地每年可向大湾区负荷中心输送超430亿千 瓦时电能，约为三峡电站年发电量的一半，且100%为清洁能源，可替代标煤消耗约1200万吨，减少二 氧化碳排放约3300万吨。该工程总投资约532亿元，配套"水风光一体化"电源基地投资超过1500亿元， 可有力带动一系列上下游装备、施工产业增长，高峰期预计将带动直接就业10万余人。 （文章来源：经济日报） ...
