蒙西—京津冀±800千伏特高压直流工程开工

Core Viewpoint - The commencement of the Mengxi-Beijing-Tianjin-Hebei ±800 kV UHVDC project by State Grid Corporation of China marks a significant step in enhancing green energy transmission and supporting the development of the "Shage Desert" renewable energy base in Inner Mongolia [1][2]. Group 1: Project Overview - The Mengxi-Beijing-Tianjin-Hebei project will span approximately 700 kilometers, starting from the Daqing Station in Ordos, Inner Mongolia, and ending at the Xiongnan Station in Cangzhou, Hebei, with a rated voltage of ±800 kV and a capacity of 8 million kW [1]. - The total investment for the project is approximately 17.2 billion RMB, with an expected completion and operational date set for 2027 [1]. Group 2: Environmental Impact - Once operational, the project is expected to deliver over 36 billion kWh of electricity annually to the Hebei load center, replacing 6.3 million tons of standard coal and reducing carbon dioxide emissions by 16.6 million tons [2]. - The project aligns with the green development philosophy and aims to facilitate energy transition in the region [2]. Group 3: Strategic Importance - The Mengxi-Beijing-Tianjin-Hebei project serves as the first external transmission channel for the "Shage Desert" renewable energy base, which has an installed capacity of 12 million kW, contributing to a larger external transmission capacity exceeding 50 million kW [1]. - The project is part of a broader strategy to enhance the cross-regional and cross-provincial transmission capacity of the State Grid, which is projected to reach 370 million kW by the end of 2025 [2].
