Germany’s slow replenishment of natural gas reserves could jeopardize the European Union’s upcoming heating season as winter approaches. The country, which accounts for more than 20% of the EU’s underground storage facilities, plays a critical role in regional energy security.
Typically, gas storage operators pump fuel during summer when prices are lower and draw from these reserves to meet winter demand. However, this year’s situation was complicated by rising gas prices and disruptions in fuel supplies from Persian Gulf countries.
The European Union is experiencing slower-than-usual filling of its underground storage facilities. Insufficient reserves by the start of the heating season could increase Europe’s dependence on current supply streams and drive up costs for gasoline and household services.
According to data reported by Gas Infrastructure Europe, net gas injection into Europe’s underground storage facilities dropped to the lowest level in six years by the end of July this year. The volume of injection fell to 9.6 billion cubic meters—the lowest figure in two years—and amounted to only 8.5 billion cubic meters overall, representing a 21% decline compared to last year and the smallest since 2020.
The Financial Times reported on June 29 that Europe risks facing winter with minimal gas reserves, which could push occupancy rates by November to just 76%. This level has not been seen since 2011.
Additionally, the European Union purchased a record amount of LNG from Russia in 2026, accumulating 9.89 million tons during the first half of the year.
Recent heat waves and disruptions in the Strait of Hormuz have further complicated Europe’s preparations for winter.
