According to the latest data from China National Pipeline Network Group, as of July 10, 2025, the North South Energy Corridor has transported over 100 billion cubic meters of natural gas and operated safely for more than 2000 days. This pipeline is a key energy infrastructure project in China's 14th Five Year Plan, starting from Heihe City in Heilongjiang Province in the north and ending in Shanghai in the south, passing through 9 provincial-level administrative regions with a total length of over 5000 kilometers.

As China's first fully autonomous long-distance pipeline, the North South Gas Pipeline has achieved 100% localization of key equipment such as 36 high-power compressor units, innovatively applied construction technology in high-altitude areas, and built an integrated intelligent patrol system for the sky and ground. After the full line is completed in 2024, the annual gas transmission capacity will reach 38 billion cubic meters, which can meet the annual gas demand of 130 million households.

This pipeline is interconnected with systems such as the Northeast Pipeline Network and the West East Gas Pipeline, forming a national gas supply network. In the first half of 2025, 15.7 billion cubic meters of natural gas will be transported to the Yangtze River Delta region, accounting for 33% of the region's total gas consumption. During the peak summer season, the daily gas supply reached 60 million cubic meters, a year-on-year increase of 4%, effectively alleviating the gas pressure in East China.

In terms of ecological protection, the project establishes a mechanism for replanting and greening, with a natural gas transportation capacity of 100 billion cubic meters equivalent to planting 820 million fir trees and purifying 420 billion cubic meters of air. This channel not only ensures energy supply to regions such as Northeast China, Beijing Tianjin Hebei, and the Yangtze River Delta, but also promotes the green transformation of industries along the route, providing important support for China to achieve its carbon peak and carbon neutrality goals.
