The China National Oil and Gas Corporation (CNPC) and JSC “UZBEKNEFTEGAZ” have begun preparing a project for the construction of the fourth string (line D) of the Central Asia-China gas pipeline, the raw material base of which is the fields of Turkmenistan. It will pass through the territory of the Surkhandarya region, connecting the gas infrastructure of Uzbekistan with the Tajik section of the new energy highway.
In Tajikistan, this project is being implemented by Trans-Tajik Gas Pipeline, a joint venture created by CNPC and TAJIKTRANSGAZ. At present, the construction of the first facility, a tunnel with a length of 1.56 km, is nearing completion on the gas pipeline in the Alai Mountains. This year it is planned to begin construction of four more tunnels.
As you know, the Central Asia-China gas pipeline includes three parallel lines (A, B and C) that run along the route Turkmenistan-Uzbekistan-Kazakhstan-China. The main volume of gas supplies to China – 35-40 billion cubic meters per year – is provided by Turkmenistan.
Line D will be laid from the border of Turkmenistan through the territory of Uzbekistan, Tajikistan and Kyrgyzstan. It is designed to supply gas to the southern and central part of the Xinjiang Uygur Autonomous Region of China. Its length is about 1000 km, throughput – 30 billion cubic meters of gas per year. The total cost of the project is 6.7 billion US dollars.
The governments of all countries participating in the project have repeatedly declared their interest in the construction of the fourth string of the Central Asia-China gas pipeline. So, in China it is considered as another important step towards diversification of natural gas imports, the demand for which is growing from year to year.
In accordance with intergovernmental agreements, after the commissioning of the fourth branch of the Central Asia-China gas pipeline, the supply of natural gas from Turkmenistan to China will increase to 65 billion cubic meters per year.
