A report from the Institute for Energy Economics and Financial Analysis warned that the European Union may need to curtail gas demand by 7 percent this winter to manage a shortfall of 14 billion cubic metres, equivalent to the power needs of up to 12 million households. Storage sites stood at roughly 72 percent full in early October 2026, the lowest seasonal level since data collection started in 2011, according to the IEEFA assessment. The shortfall has been exacerbated by a challenging summer injection period, flat import levels and a rebound in winter gas consumption over the past two years, the think tank’s analysis found.
The European Network of Transmission System Operators for Gas released its winter supply outlook on October 8, 2026, projecting that a severe cold spell combined with limited LNG arrivals could leave reserves below 30 percent by spring. ENTSOG data showed that such a drawdown would increase vulnerability to late-winter demand spikes and hinder refill operations the following summer. The operators emphasised the importance of maintaining strong LNG deliveries to support the overall gas balance across the bloc.
An upcoming European Union ban on long-term contracts for Russian liquefied natural gas, effective from January 2027, is expected to remove an additional 7 billion cubic metres from available supplies. Russian gas had historically helped manage seasonal swings, but the continent now depends more heavily on storage after pipeline deliveries were curtailed in earlier years, the IEEFA report stated. This shift has contributed to higher net withdrawals, which reached 22.6 billion cubic metres in January 2026 compared with 17.8 billion cubic metres in January 2024.
The Gas Coordination Group convened by the European Commission on October 8, 2026, reviewed the outlook and concluded that existing infrastructure retains sufficient flexibility to meet demand through expanded LNG imports. A statement from the Directorate-General for Energy noted that regasification capacity of approximately 145 billion cubic metres per winter season can help compensate for thinner storage reserves. Officials added that the current situation differs markedly from the 2021-2022 energy crisis due to diversified supplies and reduced overall gas consumption achieved under the REPowerEU framework.
Ana Maria Jaller-Makarewicz, lead energy analyst for IEEFA’s Europe team, described the increased reliance on storage as creating a major financial exposure for the region. “An increased reliance on gas storage has become a major financial liability for Europe,” she said in the report. Covering the gap with additional imports at current prices inflated by Middle East disruptions could cost an extra 3 billion euros, a 12 percent premium on last year’s equivalent volume, according to IEEFA estimates.
Localised shortfalls of up to 12 percent on peak days could materialise in southeastern Europe under the more challenging scenarios modelled by ENTSOG, which assumed no Russian pipeline gas and potential disruptions to other import routes. The European Commission has permitted member states to target 75 to 80 percent storage by November 1 rather than the usual 90 percent requirement. Authorities pledged to continue close monitoring of storage levels, prices and supply developments in coordination with national governments and market participants throughout the season.
