Transportation and underground storage in Russia
In Russia, Gazprom operates a gas transportation system of a unique scale and characteristics,
infallibly providing highly reliable supplies. This makes OAO Gazprom an attractive
energy partner.
Gazprom operates the world’s largest gas transportation system.
Its core structures are part of Russia’s Unified Gas Supply System that comprises gas production,
transportation, processing and underground storage facilities located in the European
part of Russia and Western Siberia. Centralised management, highly ramified structure and redundant
transportation routes provide substantial robustness, together with efficient and uninterrupted
gas supplies.
The Group also owns trunk gas pipelines in the Russian Far East: Sakhalin — Khabarovsk —
Vladivostok, Oktyabrsky — Khabarovsk, and Sobolevo — Petropavlosk-Kamchatsky.
Stable operation of the gas transportation system is viewed as a high priority by the Company.
The reliability of the gas transportation system has an impact on OAO Gazprom’s financial performance
and reputation overseas as well as in Russia.
At the 2014 year-end, the length of the GTS was 170.7 thousand km. The GTS comprises 250
compressor stations including 3,825 GPUs with the total capacity of 46.1 GW. Moreover, gas is
supplied to the GTS through gas pipelines of gas production and processing subsidiaries and
OOO Gazprom PHG, measuring 4.5 thousand km overall.
Gazprom’s gas transportation system: reliability pillars
— Inherent design reliability.
— Multiline sections of large diameter pipelines (1,420, 1,220 and 1,020 mm) in key transportation corridors,
all operated in the same process conditions.
— A well-developed network of underground gas storage facilities located in key consumption areas.
— Centralised operation and maintenance.
— Inter-system connections and backup gas pumping units (GPUs).
— Well-timed upgrade and overhaul.

As the GTS owner, Gazprom provides independent suppliers with non-discriminatory access
to its gas pipelines, provided that there is available capacity and that the company applying for
gas transportation has a gas production license and a gas take-or-pay agreement in place. In
2014, 24 companies outside the Group transported gas via Gazprom’s GTS in Russia. In 2014,
volumes of transported gas totalled 121.1 bcm, i.e. a 8.7% growth y-o-y. Competition kept
increasing in the gas market in 2014, driven by more favourable business conditions offered to
independent producers than to Gazprom.
