Core Viewpoint - The approval of the "Dalat—Mengxi 1000 kV AC Transmission and Transformation Project" marks a significant step in China's energy infrastructure, enhancing the transmission capacity from Inner Mongolia to the Beijing-Tianjin-Hebei region and supporting the country's clean energy goals [1][2]. Group 1: Project Details - The Dalat—Mengxi project includes the construction of a new 1000 kV substation at Dalat, with two sets of 3 million kVA transformers, and a double-circuit 1000 kV line spanning 2×124.6 kilometers, with a total investment of 4.374 billion yuan [1]. - The project is part of the key initiatives outlined in China's 14th Five-Year Plan for electricity, and it is the first supporting project for the ±800 kV UHVDC transmission project in the Beijing-Tianjin-Hebei area [1]. Group 2: Economic and Environmental Impact - The construction of the project is expected to generate multiple benefits, including stimulating investment, creating jobs, and restoring the ecosystem, while meeting the power transmission needs of the UHVDC project [1]. - The project is crucial for converting resource advantages in western China into economic benefits, facilitating large-scale consumption of clean energy, and promoting coordinated development in the Beijing-Tianjin-Hebei region [1]. Group 3: Future Developments - The State Grid Mengdong Electric Power Company aims to expedite preliminary procedures and land acquisition, targeting construction to begin in April 2026, ensuring synchronization with the ±800 kV UHVDC project [1]. - The "15th Five-Year Plan" includes the construction of 12 UHV transmission line projects, which will increase Inner Mongolia's total transmission capacity to 96.7 million kW, with an expected external power delivery exceeding 1 trillion kWh during this period [2][3].
