The reports contain Union-wide simulations on gas storage, supply scenarios and possible exports to neighboring countries. Different scenarios and LNG supply potentials were analyzed.
The most important results at a glance
- On April 1, 2025, EU gas storage was at 34% (388 TWh) - lower than in previous years due to high storage withdrawals in winter.
- To get off to a good start in winter 2025/26, Europe needs more LNG inflows than in recent summers. According to ENTSOG, early injection is crucial.
- Unplanned maintenance work could put additional pressure on the injection phase.
- European gas infrastructure - including new LNG terminals - strengthens flexibility and security of supply in the EU.
- According to ENTSOG, an adequate supply of LNG is necessary to avoid supply bottlenecks in the event of a complete Russian supply failure or a long injection phase.
For the coming winter, ENTSOG shows that a storage level of 34% at the start of the summer is sufficient to maintain a level of over 30% by the end of the winter, taking into account storage and import capacities - in all EU member states.
Review of summer 2024
- Gas consumption in the EU fell by 2.7 % compared to summer 2023 and by as much as 17.9 % compared to the five-year average.
- Total gas supply fell by 6.4%, partly due to lower demand and high storage levels at the start of the season.
- The share of LNG in supply fell to 29% (after 37% in summer 2023).
- Norway remained the largest pipeline supplier; the share of pipeline gas totalled 53,5 %.
ENTSOG Director General Piotr Kuś emphasises the role of storage facilities: “It is crucial to start injecting energy at an early stage and to continuously monitor storage levels in order to ensure security of supply in winter.”
