Route and Technical Description
Lines A, B, and C
The operating pipeline consists of three parallel segments, known as Lines A, B, and C, running parallel to each other. The pipeline runs through Turkmenistan, Uzbekistan, Kazakhstan, and China. Each segment measures about 1,833 km in length; 188 km of the pipeline are in Turkmenistan, 530 km in Kazakhstan, and the remaining 1,115 km of the pipeline run from Kazakhstan to China. The predominant share of the gas supply, about 80%, comes from Turkmenistan. The pipeline is supplied from the Galkynysh and Dauletabad gas fields, as well as from the Bagtyyarlyk gas field in Turkmenistan, where it originates. The pipeline is also supplied with gas from the Beineu-Bozoy-Shymkent Gas Pipeline to which it is linked in Shymkent, Kazakhstan. The Beineu-Bozoy-Shymkent Gas Pipeline delivers gas originating in gas fields of Kazakhstan.
The pipeline enters Uzbekistan in Olot and runs across Uzbekistan to Southern Kazakhstan parallel to the Bukhara-Tashkent-Bishkek-Almaty Gas Pipeline. The pipeline then crosses the Kazakhstan - China border at Horgos, where it connects to the West-East Gas Pipeline 2.
Line A is 1,833 kilometers in length and has a capacity of 15 bcm/year. It was inaugurated in December 2009. Line A is owned and operated by CNPC.
Line B is 1,833 kilometers in length and has a capacity of 15 bcm/year. It was inaugurated in October 2010. Line B is owned and operated by CNPC.
Line C is 1,833 kilometers in length and has a capacity of 25 bcm/year. It became operational in 2014. Line C is owned by CNPC 52%, Baosteel (16%), China NCSSF (16%) and China Urban Infrastructure Fund (16%).
The route of Line D segment of the pipeline is different from the other three segments. It will run across five countries, from the border of Turkmenistan through the territories of Uzbekistan, Tajikistan and Kyrgyzstan, and China. It is planned to originate at the Galkynysh gas field in Turkmenistan. In Tajikistan, the gas pipeline will run through Tursunzoda, Shahrinav, Hisor, Roudaki, Vahdat, Fayzobod, Nourobod, Rasht and Lakhsh (formerly Jirgatol) to Kyrgyzstan’s border. It will then go through Kyrgyzstan, crossing into China near the village of Irkeshtam on the Kyrgyzstan-China border.
Line D is planned to be 966 km long with the capacity of 30 bcm/year.
Lines A, B, and C
The initial proposal for the Central Asia–China gas pipeline was presented as the Kazakhstan–China Gas Pipeline, which was to follow along the Kazakhstan-China Oil Pipeline. In June 2003, during Chinese President Hu Jintao's visit to Kazakhstan, agreements to expedite the appraisal of the project were signed. Following these agreements, KazMunayGas and PetroChina started a feasibility study of the pipeline project. At the same time, China continued negotiations with other Central Asian countries.
On 3 April 2006, China and Turkmenistan signed a framework agreement for pipeline construction and long-term gas supply. In June 2007, during his visit to China, Turkmeni President Gurbanguly Berdimuhamedow signed an accord to speed up implementation of the Turkmeni-Chinese gas pipeline project. On 30 April 2007, Uzbekistan and China signed an agreement on the construction and exploitation of the pipeline's Uzbekistan section. In July 2007, it was formally announced that Turkmenistan will join original Kazakhstan-China pipeline project. On 8 November 2007, Kazakhstan's oil company KazMunayGas signed an agreement with the China National Petroleum Corporation on principles of future work on the pipeline.
On August 30, 2007, the construction of the 188-kilometer long Turkmen section of the pipeline began. This section was built by Stroytransgaz, a subsidiary of Gazprom. Main contractors were China Petroleum Pipeline Bureau, China Petroleum Engineering and Construction Corporation, and Zeromax. Construction of the Uzbek section started on June 30, 2008. It was built by Asia Trans Gas, a joint venture of Uzbekneftegas and China National Petroleum Corporation. Construction works of the Kazakh section started on July 9, 2008, and the first stage was finished in July 2009. It was built by Asian Gas Pipeline company, a joint venture of CNPC and KazMunayGas. The main contractors of this section were KazStroyService and China Petroleum Engineering and Construction Corporation. The first of the two initial parallel lines were completed in early November 2009.
The Kazakh section of the pipeline was inaugurated on December 12, 2009 during Chinese President Hu Jintao's visit to Kazakhstan. The whole pipeline was inaugurated on December 14, 2009 in a ceremony in Saman-Depe during Hu Jintao's visit to Turkmenistan with the leaders of Turkmenistan, Uzbekistan and Kazakhstan. On June 13, 2010, China and Kazakhstan signed an agreement on a branch line from Western Kazakhstan.
The second line was completed by the end of 2010. Construction of the third line began in 2012. It became operational on June 15, 2014, and is expected to reach the designed throughput of 25 billion cubic meters per annum in December 2015.
Line D would be 1,000 kilometers in length and would carry an additional 30 billion cubic meters per year of gas from Turkmenistan's gas fields to the Chinese border through Uzbekistan, Tajikistan and Kyrgyzstan. Line D would be operated by the Trans-Asia Gas Pipeline Company Ltd (Trans-Asia Gas), a subsidiary of CNPC, and Tojiktransgaz.
China signed agreements with Uzbekistan, Tajikistan and Kyrgyzstan to build a fourth line of the Central Asia-China Gas Pipeline in September 2013. 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. Because the Tajik section is the longest and the most challenging segment of the pipeline, in 2014 the stakeholders decided to start the construction process from Tajikistan. Construction was planned to start in 2014 but was postponed for technical reasons until 2018.
In November 2018, the operating pipeline was working at its maximum capacity which underscored the need for an additional segment to be constructed. The demand for gas in China is increasing with each year, necessitating this project to move forward. Construction partially resumed in January 2018 and was expected to be completed by 2020. In January 2020, it was reported that construction was suspended but that the pipeline was expected to be completed by 2022. In January 2020, the first tunnel project, the first mountain-crossing effort, was completed.
In June 2021, several deals were finalized related to the pipeline. In one, a subsidiary of CNPC has won a tender from Turkmengaz for developing new wells at the Galkynysh gas field; in another, Kazakhstan-based Sozak Oil and Gas JSC was reportedly close to finalizing a $1.2 billion EPC contract with China’s CAMC Engineering for a natural gas project that involves well drilling, exploration, and pipeline work in the Kazakhstani regions of Turkistan and Kyzylorda. These two recent agreements may indicate a renewed momentum for the continued construction of the pipeline.
Initial financing for the pipeline of US$11 billion in loans was provided in November 2008 by China Development Bank and Bank of China.
