History

The system was built between 1960 and 1988. Construction began after discovery of the Dzharkak field, and the first section of the pipeline was completed in 1960. CAC-1 and 2 were commissioned in 1969 and CAC-4 was commissioned in 1973. In 1976, two parallel lines were laid between Shatlyk compressor station and Khiva

. CAC-5 was commissioned in 1985 and in 1986-88 the Dauletabad–Khiva line was connected. The western branch (CAC-3) was constructed in 1972-1975.

Technical features

Almost all Uzbek and Turkmen natural gas is delivered through the CAC pipeline system, mainly through the eastern branch due to location of production sites and poor technical condition of the western branch. CAC-1, 2, 4 and 5 pipelines are supplied from gas fields in the South-East of Turkmenistan, mainly from the Dauletabad gas field

 CAC pipelines meet with Soyuz and Orenburg–Novopskov pipelines. From there two lines run northwest to Moscow, and two others proceed across the Volga river to the North Caucasus-Moscow transmission system. The diameter of most pipelines varies from 1020 to 1420 mm (40.2 to 55.9 in). Current capacity of the system is 44 billion cubic meters (bcm) per year. An agreement is in place to increase capacity to 55 bcm per year by 2010 and through modernization there is potential to increase capacity to 90 bcm per year.

Caspian coastal pipeline

On 20 December 2007, Russia, Turkmenistan and Kazakhstan agreed to construct a new Caspian pipeline parallel to the existing CAC-3 pipeline. The pipeline is planned be built between Belek compressor station in Turkmenistan and Alexandrov Gay compressor station. Capacity of the new pipeline will be 20–30 bcm per year and it would be supplied from the planned East–West pipeline
