Germany relies on state gas buyers and options as storage sits at 56%

Federal intervention and storage levels

German Economy Minister Katherina Reiche has initiated talks with state-owned energy companies SEFE and Uniper to accelerate gas purchases ahead of the heating season. Storage facilities across Germany held 56% of their total working capacity as of mid-September 2026, down significantly from previous years. Federal Network Agency president Klaus Müller confirmed on 16 September that the statutory target of reaching 80% capacity by 1 November is no longer achievable. Germany operates approximately 45 underground cavern and pore storage facilities across its territory with a total capacity of nearly 24 billion cubic meters, representing about one quarter of annual domestic gas consumption. While the federal government owns 100% of SEFE and 99% of Uniper, the economy ministry stated that no formal shareholder instructions were issued, leaving procurement to commercial management.

Market mechanisms and LTO tenders

To encourage gas injections without direct interventions that could distort prices, the economy ministry supports expanding Long Term Options (LTOs) tendered by Trading Hub Europe. Under this mechanism, pipeline operators pay fees to commercial traders to keep designated volumes in reserve at specific regional hubs, creating incentives to store gas even during high-price periods. Both the energy industry association BDEW and storage operator group INES previously urged the government to expand these option tenders. Storage operators offer capacity as an infrastructure service rather than buying commodities themselves, leaving inventory decisions to energy suppliers, municipal utilities, power plants, and industrial consumers. Sebastian Heinermann, managing director of INES, highlighted the functional purpose of subterranean facilities:

Together, both storage types make it possible to shift gas in time between supply and demand.

State Secretary Frank Wetzel pointed out that government interventions carry financial risks for the wider market:

State interventions should be considered very carefully, because they influence market activity and thus prices.

Price pressures and global supply constraints

High wholesale costs during summer 2026 disrupted typical seasonal storage strategies, in which traders buy cheaper summer gas to sell during winter peak demand. Day-ahead natural gas contracts at Trading Hub Europe traded around 81 euros per megawatt-hour on 15 September 2026, up from approximately 55 euros per megawatt-hour on 10 August. Market disruption stemming from the war involving Iran has constrained international supply expectations and removed expectations of lower off-season pricing. ICIS gas market analyst Andreas Schroeder noted that previous delays in intervention reflected rational timing given global uncertainties:

It is expected that the world will have to get through the winter without gas supplies from Qatar, and prices are already historically high.

Liquefied natural gas competition with Asia

European gas supply stability during the upcoming winter depends on competition with Asian markets for flexible liquefied natural gas imports. US export tankers heading to Asia must take longer voyages around the Cape of Good Hope due to passage restrictions in the Suez Canal. According to Montel energy calculations, Asian prices must exceed European rates by roughly 7 euros per megawatt-hour to offset higher shipping costs and divert deliveries away from Europe. Montel analyst Joachim Endress stressed the broader impact on regional balances:

The competition between Europe and Asia for liquefied natural gas should significantly determine price developments in Europe throughout the entire winter.

While newly built domestic liquefied natural gas terminals provide an additional import route for Germany, inventory deficits persist across storage sites. SEFE has commenced purchasing gas to fill booked capacity, including the country's largest underground storage site at Rehden in Lower Saxony, while Uniper reports higher relative fill rates across its own facilities.
