中国基金报·2025-09-16 09:29Core Viewpoint - The construction of the Zang-Guangdong DC project marks the initiation of the world's strongest flexible DC transmission project, which will deliver over 43 billion kilowatt-hours of clean energy annually to the Guangdong-Hong Kong-Macao Greater Bay Area after its full operation in 2029 [2][3]. Group 1: Project Overview - The Zang-Guangdong DC project is a key cross-province transmission project under China's 14th Five-Year Plan, with a total length of approximately 2,681 kilometers and a transmission capacity of 10 million kilowatts [2][3]. - The project is expected to replace approximately 12 million tons of standard coal consumption and reduce carbon dioxide emissions by about 33 million tons annually [2][3]. Group 2: Investment and Economic Impact - The total investment for the Zang-Guangdong DC project is approximately 53.2 billion yuan, with an additional investment of over 150 billion yuan for the supporting "water-wind-solar integrated" power generation base [3]. - The project is anticipated to create over 100,000 direct jobs during peak construction, significantly promoting the economic and social development of Tibet [3]. Group 3: Technological Challenges and Innovations - The project faces significant challenges, including the development of new technologies for ultra-high altitude DC transmission and the integration of 20 million kilowatts of renewable energy into a weak grid [4][5]. - The project aims to establish a new model for energy production and consumption, contributing to China's dual carbon goals through high-level technological self-reliance and innovation [4][5]. Group 4: Collaborative Efforts - The Zang-Guangdong DC project is a collaboration between China Southern Power Grid Co., Ltd. and State Grid Corporation of China, marking another significant clean energy transmission project following previous successful collaborations [5]. - The project will leverage advanced technologies and equipment, including high-power semiconductor devices and digital twin technology, to enhance operational efficiency and reduce maintenance needs in remote areas [5].
