Europe is currently facing a significant challenge in its efforts to refill underground gas reserves ahead of the 2025/2026 winter season. By the end of May, gas levels in storage facilities were considerably lower compared to the same time last year, prompting concern across the continent.
The European Union has set a goal to reach 90% storage capacity by November 1, but achieving this target will require a much faster rate of gas injections than seen in previous years. This effort is being hindered by routine summer maintenance of gas infrastructure across Europe, further complicating storage operations.
At the same time, a reduction in liquefied natural gas (LNG) imports and intense competition from Asian markets are putting additional pressure on supply. As demand in Asia continues to rise, Europe faces difficulties in securing the necessary LNG volumes.
Data from Gas Infrastructure Europe shows that as of May 31, storage facilities across Europe held 48.6 billion cubic meters of working gas. This is 21.8 billion cubic meters less than on the same date in 2024, amounting to a shortfall of approximately 1.5 times. During May alone, only 8.9 billion cubic meters were added to storage, which is 1.1 billion cubic meters below the ten-year average for that month.
To meet the EU’s November target, operators must inject an additional 41.9 billion cubic meters over the next five months. This would require a pace of injections that is about 1.5 times greater than the volume added over the same period last year.
Storage operations are further complicated by the need to coordinate them with scheduled maintenance work, posing both logistical and technical challenges. Overcoming these obstacles is crucial if Europe is to avoid another winter marked by energy shortages.
In a statement released in June, Gazprom warned that the current pace of gas storage injections is not sufficient to ensure stable supplies during the winter. The company highlighted the urgent need for European operators to accelerate their efforts, especially as demand in Asia grows and global energy market dynamics continue to shift.
Unusually cold spring temperatures and reduced LNG imports have already slowed the replenishment of European gas reserves. Combined with strong competition from Asian buyers, these factors are making it increasingly difficult for Europe to secure enough supply.
With time running short, energy operators in Europe must navigate operational limitations, technical requirements, and unpredictable market conditions. The ability to refill gas reserves before autumn could be a decisive factor in maintaining energy security and preventing supply disruptions in the upcoming winter season.
