Updated - The Inčukalns Underground Gas Storage facility ensures secure energy supply during winter

Revised second paragraph.

The unified gas transmission and storage system operator AS “Conexus Baltic Grid” (hereinafter – “Conexus”) informs that the natural gas withdrawal season of the Inčukalns Underground Gas Storage (UGS) facility for 2025/2026 has been completed, during which 12.36 terawatt hours (TWh) of active natural gas were withdrawn from the storage.

The highest volume of natural gas was withdrawn in January and February 2026 – a total of 7.3 TWh, which is 19% more than in the previous year. This was driven by winter weather conditions with persistently low air temperatures in the Baltic states and Finland.

The Inčukalns UGS is increasingly being used for balancing energy supply and ensuring system flexibility. To strengthen energy security and maintain stable natural gas reserves in the storage, Conexus continued to provide system users with physical injection of natural gas into the storage during the withdrawal cycle. In total, 4.5 TWh of natural gas were injected into the storage during the past withdrawal cycle, which is 1.2 TWh or 37% more than in the 2024/2025 storage cycle.

The highest monthly withdrawal volume during the season was recorded in January, reaching 4.67 TWh. Meanwhile, the highest daily consumption – 194.9 GWh – was recorded on 13 January 2026.

At the end of the withdrawal season, the volume of natural gas in storage currently exceeds 6.4 TWh.

The 2025/2026 natural gas withdrawal season began on 15 October 2025, with the storage facility filled to 58% of its available technical capacity.

Conexus has set the maximum volume of natural gas to be stored at the Inčukalns UGS for the 2026/2027 storage cycle – according to measurements and calculations carried out, this amounts to 24.4 TWh.
