EU Winter Gas Warning: Why IEEFA Sees a Possible 7% Demand Cut
IEEFA says the EU may need to balance a 14 bcm gap—about 7% of winter demand—because storage is unusually low and Russian LNG imports are due to be banned from January 2027. Storage was 72.4% full on October 3, the lowest for that time of year since records began in 2011; IEEFA estimates it could provide 7.3 bcm les...

The EU is entering winter with less gas in storage than at the same point in any year since records began in 2011. IEEFA says storage was 72.4% full on October 3 and estimates it could provide 7.3 billion cubic metres (bcm) less gas to the market from November through March than last winter. Combined with the EU’s full ban on Russian LNG imports due to begin in January 2027, that could mean balancing a 14 bcm gap—around 7% of last winter’s demand. 9
That is a warning about a tighter supply margin, not a prediction that the EU will exhaust its reserves or that households will necessarily face rationing. The Commission says the EU gas system is sufficiently flexible to meet winter demand and that infrastructure can manage higher LNG imports to compensate for lower storage. 1
What the 7% figure means
IEEFA’s estimate combines two pressures: less gas available from storage than last winter, and the need to replace Russian LNG as the import ban takes effect. The 7.3 bcm storage estimate is therefore not the same as the full 14 bcm figure. IEEFA presents the latter as a potential demand reduction compared with last winter—not as a claim that storage alone is short by 14 bcm. 9
The distinction matters. A potential gap can be balanced through some combination of additional imports and lower consumption. The estimate does not, by itself, say which consumers would use less gas or establish that mandatory household cuts are inevitable.
Why low storage raises winter risk
Storage is a buffer against periods when gas demand rises or supply is disrupted. IEEFA warns that a cold snap like January 2026 could drain reserves faster. The Commission also highlights the importance of maintaining adequate stocks through winter to cope with late cold spells and make it easier to refill storage the following summer. 9

This means a winter can be challenging even if storage is not literally emptied: a smaller buffer leaves less room to absorb a cold spell or an interruption to imports. And drawing stocks down further can leave more work for the next refill season. The available sources establish those seasonal risks, but do not quantify a specific cost for refilling or describe how fast individual storage sites can deliver gas as inventories fall.
How the other shortfall estimates compare
Politico’s report describes the potential 14 bcm shortfall as equivalent to the energy used by 10–12 million European households. That comparison communicates the scale of the volume; it is not a forecast that those households will lose service. 2
A separate ENTSOG assessment, as reported by Euronews, warns of a possible shortfall of 12% to 15% of demand if a severe cold snap occurs. That is a more severe, conditional scenario, not a direct restatement of IEEFA’s 7% estimate. 34
The underlying measures also differ. ENTSOG’s published outlook says EU storage was 72% full on October 1 and projects that it could fall to 29% by March 31 under its “LNG Optimal” supply scenario, or 13% under “LNG Tight” supply. Those are projected end-of-winter storage levels; they are not the same thing as a 7% demand cut. 41
A low starting point, but not proof of an unavoidable shortage
Low storage makes the EU more exposed to cold weather and import disruption, but storage levels alone do not determine whether the system can meet demand. The European Commission says the EU’s infrastructure can accommodate higher LNG imports and that the system remains flexible enough to meet winter demand despite lower-than-historical stocks. 1
That reassurance is about system capability; it does not establish that all the LNG Europe may need will be available, or that imports will be inexpensive. The clearest reading of the evidence is therefore two-sided: IEEFA identifies a real risk to the winter supply margin, while the Commission points to infrastructure flexibility as a buffer. The 7% figure is a scenario for balancing supply and demand—not a certainty that Europe will run out of gas. 9
