Transmission

Unified Gas Supply System of Russia

Gazprom owns the world’s largest gas transmission system, most of which 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. The UGSS assures continuous gas supply from the wellhead to the ultimate consumer.

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 the Russian Far East, namely the Sakhalin – Khabarovsk – Vladivostok and Sobolevo – Petropavlovsk-Kamchatsky gas mains.

The overall length of the gas transmission system in Russia is 172,600 kilometers. Gas transmission is performed using 254 compressor stations with the aggregate capacity of gas compressor units totaling 47,100 MW.

The Company schedules major repairs using a cutting-edge planning system based on monitoring the GTS’s technical condition and integrity. After the risk evaluation and integrated assessment are done, priority is given to the facilities the repair of which ensures better performance of the GTS. This approach allows the Company to boost the operational reliability of process facilities, reduce the workload and cut down the costs at the same time.
