Transmission

Unified Gas Supply System of Russia

Gazprom owns the world’s largest gas transmission system, the greater part of which is comprised of the Unified Gas Supply System (UGSS) of Russia. The UGSS represents a unique engineering complex encompassing gas production, processing, transmission, storage and distribution facilities in European Russia and Western Siberia. The UGSS assures continuous gas supply from the wellhead to the ultimate consumer.

Centralized control, considerable ramification and parallel transmission routes endow the UGSS with a substantial reliability margin and ability to secure uninterrupted gas supplies even under peak season loads.

Gazprom Group also owns gas mains in the Russian Far East, namely, Sakhalin – Khabarovsk – Vladivostok, Oktyabrsky – Khabarovsk and Sobolevo – Petropavlovsk-Kamchatsky.

The length of the gas transmission system in Russia totals 171.2 thousand kilometers. 250 compressor stations with the aggregate capacity of gas compressor units equaling 46.2 thousand MW are used for gas transmission.

Access for independent gas producers

Gazprom provides independent companies with non-discriminatory access to gas pipelines. In 2015 Gazprom’s GTS in Russia pumped gas for 22 independent companies. The volume of distributed gas stood at 121.5 billion cubic meters.

Gas transmission system reliability

Reliable operation of the gas transmission system (GTS) is secured by advanced inspection methods as well as well-timed preventive maintenance and repair operations. It is objectively proved by the smaller number of technical failures on gas pipelines – since 2003 it has decreased by six times and made up 0.03 per one thousand kilometers in 2014.

The Company carries out overhauls using a state-of-the-art planning system based on monitoring the GTS’s health and integrity. After the risk evaluation and integrated assessment is done, the priority in repair is given to those facilities, which ensure better performance of the GTS. Such an approach allows increasing the operational reliability of process facilities, reducing the workload and cutting down the costs.

Gas transmission system development

Gazprom is building gas transmission facilities in order to improve the reliability of gas supply, boost the gasification and gas distribution across Russian regions as well as fulfill its export obligations. Particularly, between 2010 and 2015 the Company commissioned around 10,000 thousand kilometers of gas mains in Russia.
