If countries hope to restore their reserves to 30% by the end of winter — or else face increased exposure to future cold spells — volumes equivalent to 7% of the demand will either have to be curtailed or simply withheld from consumers, ENTSO-G warns.
Part of that pressure comes from a looming EU-wide ban on long-term supply contracts for Russian LNG, due to take effect in January, which will reduce European gas imports by an additional 7 billion cubic meters, according to the IEEFA report. Russian gas has been historically used to offset “swings in demand” over the winter, it said. “Now Europe depends on storage to get through winter.”
To make matters worse, the IEEFA report argues, gas demand over winter has crept up in the past two years, while imports to the bloc have flatlined. That’s left the EU leaning harder on its reserves over the winter period, with net drawdowns rising to 22.6 billion cubic meters in January this year, up from 18.8 billion cubic meters in January 2025 and 17.8 billion cubic meters in January 2024.
The alternative would be to import fresh LNG, a seaborne fuel that the EU increasingly sources from the U.S. But at current prices, importing the lost volumes would cost Europeans an additional €3 billion, a 12% rise over what the same volume would have cost last year, on top of already sky-high prices, according to the report. U.S. LNG production is also near full capacity, meaning those additional imports would further squeeze supply, Jaller-Makarewicz told POLITICO.
To some, a rise in prices is more likely. While ENTSO-G’s tight market scenario assumes a “global deficit” that sees available LNG imports into Europe reduced by 20%, Laurent Ruseckas, a senior gas market analyst at S&P Global Energy, argues that reserves can only ever fall so low, “since a rapid drawdown early in winter will drive up prices,” drawing cargoes to Europe from Asia.
“There is not much demand to destroy in Europe,” he added, pointing out that the war in Ukraine already destroyed 20% of the bloc’s industrial demand. “And it didn’t come back.”
