Kaliningradskoye underground gas storage 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: 2.

Working gas inventories: up to 70 million cubic meters.

Daily deliverability: up to 6 million cubic meters.

Development

The construction of the Kaliningradskoye UGS facility started in 2009.

In September 2013, Gazprom completed Phase 1 of the project, which included the construction of two underground reservoirs and pertinent compressor capacities. A 26-kilometer-long 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 continue. It is planned to put onstream two additional reservoirs in late 2017 and to increase their number 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.

Technologies

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.
