Jiangsu's provincial natural gas pipeline network has achieved a crucial connection with the national trunk pipeline network at a key node in northern Jiangsu. This milestone follows the official commencement of gas transmission and operation of the interconnection project between the Jiangsu Coastal Natural Gas Pipeline's Huaijianyan Project and the Qingning (Qingdao-Nanjing) Natural Gas Pipeline. As a significant step in integrating the provincial pipeline network into the national unified grid, the project's operation will further solidify the energy supply foundation for the Yangtze River Delta region and inject robust momentum into regional green and low-carbon development.
The interconnection project originates from the Qingning Pipeline's Huai'an Offtake Station and terminates at the Jiangsu Coastal Pipeline's Zhuqiao Offtake and Connection Station. With a design pressure of 10 megapascals and an annual gas transmission capacity of 30 billion cubic meters, it represents the second national-level interconnection channel completed for the Jiangsu Coastal Pipeline, following the connection between the Huaijianyan Project's Jianhu Offtake Station and the China-Russia Eastern Route's Yancheng Station. A third national-level interconnection channel, the Rutaitai Project's Haimen Offtake Station, has already achieved physical connection with the China-Russia Eastern Route.
This new connection enables deep integration between the major north-south energy arteries, establishing a new pattern of energy transmission characterized by bidirectional flow and flexible dispatch. The Qingning Pipeline serves as a core link connecting North China with the Yangtze River Delta, coordinating both onshore and offshore gas sources. The Jiangsu Coastal Pipeline, as a key provincial energy supply entity, connects multiple large-scale gas storage facilities and LNG receiving terminals, acting as a critical hub between the national pipeline network and the provincial market. Their interconnection marks the fundamental formation of the provincial network's deep integration into the national unified grid framework. The project precisely matches the needs for off-peak injection and withdrawal from storage facilities, seasonal peak shaving, and emergency response during extreme conditions. It effectively enhances the stability, reliability, and emergency supply capacity of regional natural gas, contributing to the construction of a diversified and complementary energy supply system characterized by "northern gas moving south, offshore gas landing, and storage facilities for peak shaving."
