Brussels: Underground gas storage facilities in the European Union are around 36% full, marking a 23% decline compared to the same period last year, APA-Economics reports, citing Gas Infrastructure Europe (GIE). Currently, total gas volume in storage stands at approximately 39 billion cubic meters, which is 42% less than the previous year.

According to Azeri-Press News Agency, since the start of the heating season on October 29, 2024, EU countries have withdrawn over 74 billion cubic meters of gas from underground storage. The heating season concluded on March 28, 2025, and as of now, the gas in storage totals 38.2 bcm.

Under European Commission regulations, EU members are required to fill 90% of gas storage by November 1 each year to ensure winter supply security in case of disruptions or extreme cold. This requirement translates to at least 61 bcm of net gas injection needed during the upcoming storage cycle, which is almost 50% higher than last year and among the highest levels on record.

Notably, Azerbaijan has been supplying gas to Europe via the Trans-Adriatic Pipeline (TAP) since December 31, 2020.
