中国首个跨越三级地理阶梯的特高压直流输电工程启动建设

Core Points - The construction of the Zang-Yue DC project, the first ultra-high voltage direct current transmission project crossing the Qinghai-Tibet Plateau, Yunnan-Guizhou Plateau, and South China Hills, has commenced, supporting China's green economic development [2][4] - The project has a total investment of approximately 53.2 billion yuan and will transmit clean energy from Tibet to the Guangdong-Hong Kong-Macao Greater Bay Area [2][3] Group 1 - The Zang-Yue DC project is characterized by three "super" features: ultra-high altitude, ultra-long distance, and ultra-large capacity [2][3] - The project will face significant challenges, including high-altitude technology development and construction in complex natural environments [2][4] - The project will have a rated transmission capacity of 10 million kilowatts, delivering over 43 billion kilowatt-hours of electricity annually to the Greater Bay Area after full operation in 2029 [3] Group 2 - The project aims to solve global challenges related to large-scale clean energy transmission and the application of ultra-high voltage technology in extreme conditions [4] - The clean energy transmitted will replace approximately 12 million tons of standard coal consumption and reduce carbon dioxide emissions by about 33 million tons [4]
