Ukrainian UGS facilities will undergo additional independent technical review to confirm reliability in wartime conditions

Naftogaz Group company Ukrtransgaz and the Operator of the Gas Transmission System of Ukraine (OGTSU) will conduct stress tests to confirm the reliability of the country’s gas transportation system and underground storage facilities amid shelling and the potential cessation of Russian gas transit. The results of this review will be disclosed at the end of April 2024.

The assessment will be carried out by an independent working group including representatives from USAID’s Energy Security Project, the Secretariat of the Energy Community, Joint Research Centre of the European Commission, GTSOU, Naftogaz of Ukraine, Ukrtransgaz, and international technical experts.

Similar tests were conducted in 2023, confirming the reserve capacity of UGS and the maneuverability of Ukraine's gas transportation system to ensure gas withdrawal and transportation to EU borders, even during Russian military attacks on the country's gas infrastructure.

In 2023, Ukrtransgaz became the second operator of gas storage facilities in Europe to successfully undergo certification according to new EU rules.

In 2024, Naftogaz Group offers foreign clients up to 10 billion cubic meters of free capacity in the country’s UGS, representing one-third of Ukraine's underground storage capacity.

Last year, foreign traders and energy companies stored 2.5 billion cubic meters of gas in Ukraine’s UGS. This year, Naftogaz Group aims to increase this volume to 4 bcm.
