12-15% Shortfall: EU Gas Network Operators Warn of Winter Supply Gap
October 10, 2026 · Frisian News
Europe's gas network operators project a 12 to 15 percent supply shortfall in a severe winter, with storage at 72 percent of capacity against 83 percent a year ago. Brussels calls the system flexible enough, but the ENTSOG figures point in a different direction.
Twelve to fifteen percent. That is how far European gas demand could outstrip supply this winter if a severe cold spell arrives alongside a disruption on one of the bloc's main import routes. The figure comes from ENTSOG, the European Network of Transmission System Operators for Gas, which published its Winter Supply Outlook on October 8. Both scenarios modelled assume no Russian pipeline gas reaches Europe.
Storage is the first problem. EU underground facilities stood at 72 percent of capacity on October 1, according to the ENTSOG report, against 83 percent on the same date in 2025. The European Commission has already relaxed the legal target, allowing member states to aim for 75 to 80 percent by November 1 rather than the 90 percent written into EU storage rules. Even in an average winter, ENTSOG found, a tight global LNG market could push stocks to 13 percent by March 2027, close to the technical floor at which some sites stop delivering at useful pressure.
The Commission's Gas Coordination Group met on October 8 and concluded, in a statement from the Directorate-General for Energy, that "the EU gas system is sufficiently flexible to meet demand this winter." Energy Commissioner Dan Jørgensen, writing to EU capitals on September 27, described the situation as "a price crisis linking to a supply crisis" but said there was no immediate threat to security of supply. Torgrim Reitan, chief financial officer of Norwegian producer Equinor, said in August that he did not expect Europe to reach 80 percent storage before the cold arrived. He was broadly right.
The supply gap traces back to the Gulf. Iran has kept the Strait of Hormuz effectively closed since the US and Israel struck Iran on February 28, a chokepoint through which roughly one-fifth of global LNG trade used to pass, according to Brussels Signal. Iranian drones hit the Ras Laffan complex in Qatar on March 18, taking out about 17 percent of Qatari liquefaction capacity, with repairs estimated at three to five years, Brussels Signal reported. Around 8 percent of EU gas comes directly from Qatar, with Italy the most exposed member state, but the broader effect is global: Asian buyers starved of Gulf cargoes are now bidding against Europe for American shipments, and the United States has become the bloc's largest LNG supplier. The Dutch TTF benchmark traded at about €80 per megawatt-hour on October 8, up from around €72 at the end of September.
The shortfall is not evenly spread. Western Europe has new coastal LNG terminals and Norwegian pipeline supply. Central, eastern and southeastern member states have neither, and the pipes that would move gas from west to east are not always large enough. The ENTSOG report puts possible localised shortfalls in southeastern Europe at up to 12 percent on peak demand days. Its harder scenario pairs a disruption to Europipe 2, the largest offshore line serving the continent, with a complete halt to Algerian imports.
A second crunch arrives in January. Long-term contracts for Russian LNG must end on January 1, 2027 under the phase-out regulation, with spot purchases already banned. Russia supplied close to 14 percent of EU LNG imports in 2025, according to Brussels Signal. The Council approved the phase-out with 24 states in favour; Hungary and Slovakia, both landlocked and still drawing Russian gas under negotiated exemptions, voted against, and Bulgaria abstained. Jørgensen ruled out any softening of energy sanctions on April 21, noting the bloc had reduced its Russian gas dependence from about 45 percent to roughly 10 percent.
As reserves fall, solidarity will be tested. The Commission has so far managed the west-to-east flow question with voluntary commitments. Jørgensen's September 27 letter listed familiar measures: cooler public buildings, limits on outdoor heating, reduced street lighting at night. He conceded that nothing had improved since his first warning in March. Industry is where the adjustment lands in practice: energy-intensive manufacturers buying at spot prices near €80 have shown in previous winters that they cut output rather than pay.
The operators have done the maths, and at 72 percent, storage is thinner than at any equivalent point in recent years, even as the Commission says the system is sufficiently flexible to meet demand.
