新华社丨“北气南下”能源大通道输送天然气突破1000亿立方米

Core Viewpoint - The "North Gas Southward" energy corridor has achieved significant progress in ensuring national energy security and promoting green transformation, with cumulative gas transmission exceeding 100 billion cubic meters and safe operation for over 2000 days [1] Group 1: Infrastructure and Capacity - The "North Gas Southward" energy corridor, a key infrastructure built during China's 14th Five-Year Plan, runs from Heihe in Heilongjiang to Shanghai, passing through nine provinces and municipalities. Since the northern section was put into operation in 2019, it has an average daily gas transmission of over 11 million cubic meters and an annual capacity of 38 billion cubic meters, meeting the annual gas needs of 130 million urban households and benefiting over 400 million people along the route [3] - This corridor is China's first long-distance pipeline with fully domestically produced key equipment and core control systems, breaking multiple technical barriers and achieving 100% localization of critical components [3] Group 2: Technological Advancements - The construction of the corridor has filled domestic gaps in construction technology for extremely cold regions and has developed advanced detection and monitoring technologies, including fiber optic safety warning systems and intelligent inspection drones, marking a shift from technology importation to independent innovation in pipeline construction [3] Group 3: National Supply Network - The pipeline interconnects with other systems like the Northeast pipeline and West-to-East gas transmission, forming a national gas supply network that enhances emergency peak-shaving capabilities. By the first half of 2025, the corridor is expected to supply nearly 15.7 billion cubic meters of natural gas to the Yangtze River Delta, accounting for one-third of the region's current gas consumption [5] - During the summer peak demand period this year, the pipeline supplied 6 million cubic meters of gas daily to Shanghai and Zhejiang, a 4% increase compared to the same period in 2024, alleviating supply pressure in East China [5] Group 4: Environmental Impact and Green Transition - The "North Gas Southward" energy corridor emphasizes green and low-carbon principles, implementing ecological restoration mechanisms and ensuring environmental safety along the pipeline. The transmission of 100 billion cubic meters of natural gas is equivalent to planting 820 million fir trees, contributing to air purification [5] - The corridor supports the green upgrade of industries such as steel and chemicals along its route, aiding in the achievement of carbon neutrality goals [5] Group 5: Strategic Importance - The corridor acts as a "green link" connecting various national strategic regions, including the revitalization of Northeast China, coordinated development in Beijing-Tianjin-Hebei, and integration in the Yangtze River Delta. As the national unified energy market accelerates, this energy artery will continue to release potential for high-quality development and contribute to the construction of a beautiful China [6]
