Kaliningradskoye UGS facility

The Kaliningradskoye underground gas storage (UGS) facility is highly important to ensuring energy security in the region. The UGS facility helps balance seasonal swings in gas consumption and maintain flexible and reliable supplies of the blue fuel across the Kaliningrad Region.

Figures and facts

Number of storage reservoirs in operation: 4.

Working gas inventories: 156 million cubic meters.

Project implementation

The construction of the Kaliningradskoye UGS facility started in 2009.

In September 2013, Gazprom completed Phase 1 of the project consisting of two underground reservoirs and pertinent compressor capacities. A 26-kilometer gas pipeline branch was built to connect the UGS facility to the Minsk – Vilnius – Kaunas – Kaliningrad gas pipeline.

The efforts to expand the UGS facility are still underway. In December 2017, two new underground reservoirs were put onstream, which made it possible to more than double the working gas inventories from 70 to 156 million cubic meters. It is planned to increase the number of reservoirs to 14 by 2025. As a result, the UGS facility will be brought to its design capacity, with working gas inventories of 800 million cubic meters and daily deliverability of 12 million cubic meters.


Kaliningradskoye is Russia’s first UGS facility created in salt caverns, which gives it a number of advantages over storage facilities built in depleted gas fields or aquifers. Salt caverns are ideal leak-proof containers thanks to their gas-tight salt domes. Besides, the self-healing capacity of rock salt suppresses fractures and faults. Moreover, it is possible to rapidly switch Kaliningradskoye from injection to withdrawal and vice versa (multiple cycling capability), as well as to bring the UGS facility to its peak performance within the shortest possible time.

Social and economic significance

The expansion of the Kaliningradskoye UGS facility is part of Gazprom’s extensive efforts to ensure energy security, expand gas supplies, and develop relevant gas infrastructure across the Kaliningrad Region.
