Europe Enters Winter With Gas Storage at a Record Seasonal Low

European gas storage is entering the heating season at its lowest level for the time of year since records began in 2011. ENTSOG presented its 2026-2027 Winter Supply Outlook to national energy officials on Thursday, 8 October. POLITICO, drawing on that outlook and on work by the Institute for Energy Economics and Financial Analysis, reported on 9 October that the European Union could face a shortfall of up to 14 billion cubic metres this winter, about 7 per cent of demand and enough to power 10 to 12 million households.

The European Commission struck a calmer note the same day ENTSOG published. Storage is below historical levels, it said, yet the system remains flexible enough to meet demand if LNG imports rise to compensate. POLITICO put EU reserves at just above 70 per cent after a summer when high prices made it more profitable to sell gas than to inject it for winter. IEEFA's Ana Jaller-Makarewicz said the low buffer leaves the bloc vulnerable to price spikes, and that exhausting stocks this winter would leave more to refill next summer, feeding a loop of thin inventories and high prices.

ENTSOG's outlook, as summarised by POLITICO, warns that if LNG imports are limited or only "optimal" in a cold winter, storage could fall as low as 11 per cent, a floor treated as strategic and hard to tap. Restoring stocks to 30 per cent by winter's end would require curtailing or withholding volumes equal to about 7 per cent of demand. An EU-wide ban on long-term Russian LNG supply contracts takes effect in January and will remove about 7 bcm of imports, IEEFA estimates.

The Commission told the Gas Coordination Group it is implementing the REPowerEU Gas Regulation with a focus on preparing for the end of those long-term Russian LNG contracts. The Iran conflict has disrupted Gulf LNG and oil logistics since late February. ENTSOG's central message, echoed by the Commission on 8 October, is preparedness: diversified supply, more LNG capacity, lower demand than 2021-22. The refill problem is the part of the outlook that extends past this winter.
