German Gas Storage Levels Drop to Record Low at Start of Winter Heating Season

Germany has entered the winter heating season with its underground gas storage facilities filled to an average of 61 percent as of November 1, marking the lowest level recorded at the start of November since data collection began in 2011. According to figures from gas storage operators, the available volume represents a deficit of nearly 38 terawatt-hours (TWh) compared to the same period in 2025, when national storage stood at approximately 75 percent capacity.

The lower starting point follows a slow summer injection phase driven by elevated global gas prices. Conflict in the Middle East and shipping disruptions in the Strait of Hormuz raised summer spot prices above projected winter delivery costs, removing the commercial price spread that typically incentivises traders to purchase and store gas during warmer months. Entering April 2026, working gas capacity had already dropped below 25 percent following cold weather early in the year.

The Federal Ministry for Economic Affairs acknowledged on September 3, 2026, that legally prescribed fill targets—set at individual thresholds of 80 percent or 45 percent for specific locations—could no longer be met across the network. Four weeks after the ministry statement, official Katherina Reiche announced that a nationalised gas trader had been ordered to inject additional volumes into storage facilities, though national fill levels peaked at 61.75 percent on October 27 before declining. By November 10, the national average had fallen to 58.05 percent, compared to 74.66 percent on the same day in 2025.

Projections from the industry group Initiative Energien Speichern (INES) indicate reduced buffers for the months ahead. Under an INES model assuming mild weather conditions similar to 2016, a seasonal withdrawal of 39 percentage points would leave national storage at 22 percent by April 1, 2027. If winter weather matches the previous year's severity, which required a withdrawal of 52.73 percentage points, overall storage levels would drop to 8 percent, leaving several individual sites fully depleted and reducing physical extraction rates due to diminished reservoir pressure.

Storage distribution also remains uneven across federal states. The largest storage complexes are situated in Lower Saxony and North Rhine-Westphalia, while Baden-Württemberg possesses no major storage infrastructure and operators in Bavaria plan to decommission underutilised pore storage sites. Cross-border capacity includes several Austrian storage units linked directly to the German pipeline grid. Under statutory emergency frameworks, direct household heating retains regulatory priority, meaning any required supply curtailments would fall first on industrial consumers, including chemical producers that rely on natural gas as a manufacturing feed.
