Unified Gas Supply System of Russia
Gazprom owns and consistently develops a unique gas transmission system (GTS), which is the longest and the most reliable in the world. Most of the system forms part of the Unified Gas Supply System (UGSS) of Russia. The UGSS is a unique engineering complex encompassing gas production, processing, transmission, storage and distribution facilities in European Russia and Western Siberia. Even amid the peak consumption periods, Gazprom maintains the stability of its natural gas supplies to the population, power generation sector, and industrial and public utility enterprises.
Thanks to centralized control, an extensively branched structure, and parallel transmission routes, the UGSS has a substantial reliability margin and is able to secure uninterrupted gas supplies even under peak seasonal loads.
In addition, the Gazprom Group owns gas trunklines in Eastern Siberia and the Russian Far East, namely the Power of Siberia, Sakhalin – Khabarovsk – Vladivostok and Sobolevo – Petropavlovsk-Kamchatsky gas mains.
The overall length of the gas transmission system in Russia is 180.6 thousand kilometers.
