The gas pipeline, one of the four large infrastructure projects in China's 10th Five-Year Plan (2001-05), will transport clean fuel from Xinjiang to the energy-hungry Yangtze River Delta. The pipeline is constructed and owned by Petro China Co. The entire pipeline has been completed in September 2004, and has commenced commercial service at the end of 2004.
The 4,000 kilometers (2,500 mi) long pipeline runs from Lunnan in Xinjiang to Shanghai. The pipeline passes through 66 cities in the 10 provinces in China. Natural gas transported by the pipeline is used for electricity production in the Yangtze River Delta area. There is a plan to replace coal with gas in Shanghai by 2010. The capacity of the pipeline is 12 billion cubic meters (420 billion cubic feet) of natural gas annually. By the end of 2007, the capacity was planned to be upgraded to 17 billion cubic meters (600 billion cubic feet). For this purpose, ten new gas compressor stations will be built and eight existing stations are to be upgraded.
The West–East Gas Pipeline is connected to the Shaan-Jing pipeline by three branch pipelines.The 886 kilometers (551 mi) long Ji-Ning branch between the Qing Shan Distributing Station and the Anping Distributing Station became operational on 30 December 2005.
The pipeline is supplied from the Tarim Basin gas fields in Xinjiang province. The Changqing gas area in Shaanxi province is a secondary gas source. In the future, the planned Kazakhstan-China gas pipeline will be connected to the West–East Gas Pipeline.
Starting from 15 September 2009, the pipeline is also supplied with coalbed methane from the Qinshui Basin in Shanxi.
