The EU is well prepared for winter 2025-2026 and the months that follow, according to the annual Winter Supply Outlook published today by the European Network for Transmission System Operators for Gas (ENTSOG).
The report points to the essential role gas storage plays in securing the winter supply as well as the ability and resilience of European infrastructure to ensure supply can meet demand, even under severe conditions.
As in previous years, the report tested the EU’s resilience against a number of scenarios where gas supply to the EU could be disrupted. This year’s report analysed, in particular, the impact of the end of imports of Russian pipeline gas.
The report concludes:
- The EU gas system reached a storage level of 83% on 1 October 2025, showing resilience in case of further disruption to gas supply from Russia and limited supplies of LNG. This level is in the range observed in the years prior to the energy crisis.
- Even without Russian pipeline gas imports, winter can end with EU storage filled at 35%. This would provide a good basis for refilling gas storage facilities next summer.
- In scenarios where there is further major disruption in supply, the EU gas system is resilient enough to increase LNG imports and compensate for the loss of supply. This resilience can also limit the need to reduce demand for gas in case of extreme weather conditions.
Looking ahead to next summer, the report confirms the need to continue to prepare for subsequent winters by, for example, storing gas throughout the summer months and by reducing gas demand.
The report demonstrates the independence of the EU gas system from pipeline gas supplies from Russia and underlines the significant progress achieved by the EU to phase out Russian fossil fuel imports as a whole, which is the core objective of REPowerEU.
Publication of annual winter and summer supply outlooks by ENTSOG is a requirement of the EU Regulation on the internal markets for renewable gas, natural gas and hydrogen (Regulation 2024/1789 Article 26(3)).
Commissioner for Energy and Housing, Dan Jørgensen, said:
'The Winter Supply Outlook by ENTSOG brings good news as the heating season starts: the EU is well prepared for the upcoming winter. Our system is also resilient against supply disruptions, including a complete cut of Russian pipeline gas imports. This means that timely winter preparations, our diversification efforts and the replenishing of gas storage pay off. The EU is on track to become fully independent from Russian gas supplies.'
