“绿电”将闪送大湾区 输电量一年顶十年

Core Points - The construction of the "Tibet-Guangdong DC Project," the world's largest clean energy direct current transmission project, has officially begun, with a total investment of approximately 53.2 billion yuan and a length of about 2,681 kilometers [4][6] - The project aims to connect the abundant clean energy resources of Tibet, particularly hydropower, to the energy-hungry Guangdong province, enhancing regional cooperation and resource exchange [9][10] - The project is expected to deliver over 43 billion kilowatt-hours of clean electricity annually, significantly contributing to the energy needs of the Guangdong-Hong Kong-Macao Greater Bay Area [8][11] Investment and Economic Impact - The project is part of China's broader energy strategy, aligning with the 14th Five-Year Plan and the goal of developing hydropower resources in the Yarlung Tsangpo River basin [5][7] - The associated "water-wind-solar integrated" power base project is projected to exceed 150 billion yuan in investment, potentially creating over 100,000 jobs during peak construction [10] - The annual electricity output of 43 billion kilowatt-hours is equivalent to about half of the annual generation of the Three Gorges Dam and will replace approximately 12 million tons of standard coal, reducing carbon emissions by about 33 million tons [11][12] Technological and Engineering Significance - The Tibet-Guangdong DC Project is notable for being the first high-voltage direct current project to cross three geographical tiers, showcasing advanced technology and engineering capabilities [8] - The project faces significant technical challenges, including the development of new technologies for high-altitude direct current transmission and integration of large-scale renewable energy into the grid [8][10] - The project will establish four converter stations in Tibet and Guangdong, enhancing the region's energy security and facilitating the efficient flow of production factors across regions [10]
