Europe Risks Lowest Gas Stocks in 15 Years Ahead of Winter — NRG-IA

Europe has less than four months to rebuild the gas buffer needed for winter, and the market does not yet offer sufficient guarantees that storage facilities will be comfortably filled before the cold season begins. As of June 29, underground storage in the European Union held 549.62 TWh of gas, equivalent to 48.62% of available capacity. While this is an increase from early April, the starting point was unusually low following the 2025–2026 winter: just 314 TWh, or approximately 28% of capacity. According to the Financial Times, Wood Mackenzie estimates that the EU could reach approximately 76% capacity by the end of the injection season, typically in October. If this forecast holds, it would mark the lowest entry level into the cold season since at least 2011. The difference compared to recent winters is not merely statistical. In recent years, Europe entered the withdrawal season with storage levels above 90%, reducing the pressure to purchase large volumes of gas during peak demand and high-price periods. In October 2025, European inventories stood at 83%, but colder weather than in previous winters led to massive withdrawals, dragging stocks down to 28% by April 1. Europe must quickly recover a storage deficit To bring storage back toward the 90% target, ENTSOG estimated in April that Europe would need approximately 943 TWh of liquefied natural gas (LNG)—equivalent to about 86 billion cubic meters—between April 1 and September 30, while simultaneously covering current consumption and regional exports. Should Russian pipeline imports suffer further disruptions, the additional LNG requirement could rise by another 6 billion cubic meters. ENTSOG warns that landlocked countries in Central and Southeastern Europe are more exposed in this scenario, as they depend on regional network capacity and gas imported via maritime terminals in other states. The EU average masks significant disparities among member states. Italy's storage was 66.86% full, Poland's was at 70.63%, and Spain's at 73.95%. In Germany, Europe's largest gas market, the level was just 41.21%. The Netherlands stood at only 25.12%, while Romania was at 48.32%, very close to the European average. Germany and the Netherlands play a disproportionate role in the continental balance because they combine high consumption capacity, energy-intensive industries, regional infrastructure, and key roles in gas price formation in Northwestern Europe. Gulf LNG and Asian competition remain the primary risk Europe can import more LNG than before the 2022 energy crisis. New terminals and increased regasification capacity enhance system resilience, with ENTSOG estimating that European infrastructure can handle approximately 1,600 TWh of LNG during a winter season, equivalent to about 145 billion cubic meters. The issue is not merely the technical capacity to receive gas, but the competition for available cargoes and the price required to attract them to Europe. ACER reports that the EU received about 7% of its LNG imports from Qatar during the 2025–2026 winter, equivalent to roughly 4% of total European gas imports. While this share does not seem dominant, in a tight global market, any reduction in Qatari volumes can drive up the price of all available cargoes for both Europe and Asia. The European regulatory authority warns that a prolonged disruption in Qatari production through the end of the year could create a global deficit of around 26 billion cubic meters of LNG. Meanwhile, the price premium paid by Asian buyers for flexible cargoes has exceeded €20/MWh, making it harder to attract these volumes to European terminals. For Europe, the risk is not that LNG will disappear entirely from the market. The risk is that each cargo becomes more expensive, forcing European companies to compete more aggressively with Asian buyers precisely during the months when storage must be filled. Wood Mackenzie notes that the recovery of Gulf export capacities depends on the duration of the disruptions. In a rapid recovery scenario, unaffected LNG facilities could return to operation in June 2026 and reach full capacity in 2027. In a slower recovery scenario, the restart could be pushed to September 2026, with a full recovery delayed until 2028. The target remains 90%, but the market has more flexibility The European Union has not formally reduced its storage target to 80%. The reference level remains 90%, but rules adopted in 2025 allow member states to reach this goal within the October 1–December 1 window, rather than on the fixed date of November 1. The regulation allows for a 10 percentage point flexibility under difficult market conditions, and the European Commission can authorize up to an additional 5 percentage points if unfavorable conditions persist. This flexibility aims to avoid a situation where states or companies are forced to buy gas at any price simply to meet an administrative obligation. At the same time, it confirms that the European market no longer…
