Flow of natural gas from Central Asia

The Central Asia-China Gas Pipeline starts at Turkmen-Uzbek border city Gedaim and runs through central Uzbekistan and southern Kazakhstan before reaching Horgos in China's Xinjiang Uygur Autonomous region. Currently the Gas Pipeline has three lines in parallel, each running for 1,830 kilometers. Construction of Line A/B commenced in July 2008. With pipe diameter of 1,067mm, Line A became operational in December 2009, and Line B became operational in October, 2010. A delivery capacity of 30 billion cubic meters per annum was reached by the end of 2011.

Construction of Line C was started in September 2012. With a designed capacity of 25 billion cubic meters per annum, Line C’s pipe diameter is 1,219mm, 152mm larger than Line A/B. The overall welding work of the pipeline was completed at the end of 2013. On May 31, 2014, at the initial station of the Central Asia-China Gas Pipeline in Uzbekistan, the gas valve was turned on to boost natural gas from Turkmenistan to Line C, indicating the new transnational pipeline jointly built by CNPC and its Central Asian counterparts has become operational.

 

Upon completion of all supporting facilities of Line C by the end of 2015, the overall delivery capacity of the Central Asia-China Gas Pipeline will hit 55 billion cubic meters per annum. This equals to approximately 20% of China’s annual natural gas consumption, and would substitute 73 million tons of standard coal, cutting carbon dioxide and sulfur dioxide emissions by 78 million tons and 1.21 million tons every year, respectively.

 

In September 2013, China signed inter-governmental agreements with Uzbekistan, Tajikistan, and Kyrghyzstan respectively on Line D project. On March 4, 2014, CNPC's subsidiary Trans-Asia Gas Pipeline Company Limited signed an agreement with Tajiktransgaz on jointly establishing a natural gas pipeline company to manage the construction of Line D. On August 19, CNPC and Uzbekneftegaz signed an agreement on Line D of the Central Asia-China Gas Pipeline in Uzbekistan. Under the agreement, CNPC and Uzbekneftegaz will establish a JV company to construct and operate the Uzbekistan section of Line D. On September 13, construction of the Tajikistan section of Line D started. Totaling 1,000km with 840km outside China, Line D has a designed annual deliverability of 30 billion cubic meters, and is routed via Uzbekistan, Tajikistan and Kyrgyzstan to China. Upon the operation of Line D, the Central Asia-China Gas Pipeline will have an annual deliverability of 85 billion cubic meters, the largest gas transmission system in Central Asia.


Line A and Line B of the Central Asia-China Gas Pipeline are supplied by natural gas of 13bcm/a from the Amu Darya Project, and natural gas of 17bcm/a from Turkmengaz State Concern. Line C is supplied by natural gas of 10bcm, 10bcm, and 5bcm per year from Turkmenistan, Uzbekistan, and Kazakhstan respectively. And Line D will receive gas supply from the Galkynysh Gas Field in Turkmenistan.

 

On August 29, 2007, at the commencement ceremony, Turkmen President Gurbanguly Berdymukhamedov issued the license for the exploration and development of the joint block at Amu Darya Right Bank in Turkmenistan to CNPC, indicating the start-up of the Amu Darya project.

 

The No. 1 Gas Processing Plant of Amu Darya Project was started to be built in August 2007 and became operational on December 14, 2009, with an annual capacity of more than 6 billion cubic meters. The No. 2 Gas Processing Plant was kicked off on December 13, 2011 and put into operation on May 7, 2014, with an annual capacity of 9 billion cubic meters. At present, the two plants are capable of processing more than 15 billion cubic meters of natural gas per year, and the processed gas will be delivered to the Central Asia-China Gas Pipeline.

 

Construction of the Central Asia-China Gas Pipeline was faced with diverse and challenging geographical and geological conditions. Tens of thousands of workers and engineers from China, Kazakhstan, Uzbekistan and Turkmenistan worked together at this world class giant project. Thanks to the collaboration and devoted work of the constructors who have set a high standard of safety, efficiency and quality for the project, there was no fatal accident, environmental pollution and property loss happened during the construction.

 

The pipeline project is recognized as a model of sincere solidarity and mutually beneficial cooperation between China and concerned Central Asian countries. The inflow of Central Asian gas will significantly help China in meeting its energy demands and improve the nation's energy consumption mix. Also, the project will help the Central Asian countries diversify their energy exports, and promote socio-economic development in the region. The project has truly realized the balance of interests among energy exporters, transporters and consumers. The most significant point of the modern "Silk Road" lies in that neighbors in the region find more common interests and cooperative opportunities.
