DIW Warns Germany Is Not Managing Its Gas Storage Risk Before Winter
With German storage barely above 50% and November fill targets now deemed unattainable, Berlin faces a winter gas gap with no contingency in place.
The DIW head said on Wednesday (2026-09-02) that Germany is failing to adequately manage its gas storage shortfall, calling the risk "massively underestimated" and warning of scenarios the institute described as "not implausible," Montel reported. The think tank's statement was explicit on one point: policymakers are not doing enough.6
The storage numbers back the assessment. Gas Infrastructure Europe data show Germany's underground facilities stood at 50.14% on August 19 (2026-08-19). The EU-wide average that day was 61% — nearly 17 percentage points below a year earlier and close to a third lower than 2023 and 2024 levels.5
FNB Gas, Germany's gas transmission operators' association, warned on August 19 (2026-08-19) that the government's November 1 target of 71% average fill is now "virtually unattainable." Ines, the country's storage industry association, was only slightly more optimistic. German facilities may reach 76% this winter — the volume already booked by market participants — but Ines described that level as a supply risk if the season turns cold. Both figures fall well short of the EU's mandated 90% target, Montel reported.5,4
The shortfall has been building since the injection season opened in a weak position. Gas Infrastructure Europe data placed German storage at 30.6% full as of May 27 (2026-05-27), against 38.65% at the comparable point in 2025. Europe as a whole began summer refilling with stocks at just 28% after a prolonged winter drew reserves down sharply, OilPrice.com reported, citing Equinor executives.3,2
The ongoing Strait of Hormuz closure is the main structural driver. DW reported on August 20 (2026-08-20) that Germany's import difficulties stem primarily from disrupted LNG flows — supplies Berlin had been relying on after cutting its Russian gas share from 55% of national supply before the Ukraine conflict to 35%. Germany is not alone in its position: Gas Infrastructure Europe data show the Netherlands, Belgium, Slovakia, Sweden and Latvia are all under 50% full.5,1
Uniper chief executive Michael Lewis made the case for urgency in remarks reported by OilPrice.com. "If we don't fill the gas storage facilities quickly, we'll have a problem next winter," Lewis told a German newspaper. He called for government incentives to accelerate injection, arguing the current pace is insufficient to avoid shortfalls.3
Equinor's senior executives extended the warning more broadly, telling OilPrice.com that Europe faces a severe gas stock shortfall if Hormuz disruptions persist for another one to three months. That window is narrowing. The injection season runs through October and into November; if supply constraints hold through September, Germany's remaining window to close the gap before heating demand builds is short.2
Pricing reflects tighter conditions. ICE TTF front-month gas stood at €71.95/MWh (September 6, 2026-09-06), while THE M+1 was at €73.22/MWh. Ines had noted in July (2026-07-07) that a negative summer-winter spread was making it economically irrational for market participants to inject into storage — a structural disincentive that has persisted through the season, working against the very behaviour the grid requires.4
Germany's government has kept its target of 90% fill by December officially in place. FNB Gas has declared it unattainable; Ines puts the realistic ceiling at 76%. DIW's warning on Wednesday (2026-09-02) was that policymakers have produced no contingency for scenarios where even 76% proves out of reach. The pace of any Hormuz shipping recovery and temperatures through September are the variables winter-delivery traders will be tracking most closely in the weeks ahead.6,5,4
