The German government has asked state-owned energy company SEFE to buy and store an additional 8 terawatt-hours of natural gas before 15 December. The decision comes as German facilities are less full than at the same time last year and geopolitical risks remain high. Berlin describes the operation as a targeted supply security measure and says it is not a response to an imminent shortage.
German storage facilities were around 57% full at the end of September, compared with more than 70% a year earlier. Rehden, one of the country’s largest storage sites and operated by SEFE, was only around 13% full. These levels are attracting attention ahead of the cold season, when gas consumption rises for heating and industrial demand may strengthen.
Public purchasing to accelerate storage filling
SEFE will choose the timing of its market purchases. The target of an additional 8 TWh should increase the gas available in facilities before mid-December. This intervention is presented as a signal to other operators, encouraging them to meet storage obligations. Authorities want to avoid a scenario in which companies delay injections while waiting for more favourable prices.
The decision involves an economic trade-off. Buying gas in autumn can help rebuild stocks when prices and market conditions are unattractive to private operators. Public intervention can also intensify competition for cargoes and influence short-term prices. Until now, the ministry has avoided supporting purchases too early to prevent fuelling price increases; it now considers the situation warrants action.
Gas purchased by SEFE is not automatically equivalent to supply delivered and available to every consumer. It must be injected into facilities, connected to networks and withdrawn when demand requires it. Germany’s total storage capacity is estimated at around 250 TWh, but individual levels vary considerably. Gas stored at one site cannot always be accessed at the same cost or speed as volumes closer to a consumption centre.
The legacy of the break with Russian gas
SEFE is the former German subsidiary of Gazprom, placed under federal state control after the 2022 crisis. Before Russian deliveries stopped, some storage facilities and supplies benefited from regular flows from Russia. Since then, the company has had to purchase gas in more diversified markets and organise contracts, transport and receipt in a different commercial environment.
LNG terminals installed on the North Sea and Baltic coasts have allowed Germany to reduce dependence on Russian pipelines. The country also receives gas through European interconnections. Imports reported at the end of September remained stable, with pipeline deliveries and LNG cargoes. This diversification improves resilience but does not guarantee gas will always be available at the desired price.
An LNG terminal can connect Germany to a wider global market, but cargoes must be booked and transported. Competition between Asia and Europe can intensify during a harsh winter. Liquefaction, shipping and regasification costs add to this. Underground storage therefore complements access to imports, allowing purchases in advance and smoothing seasonal requirements.
New obligations and a planned strategic reserve
German regulations impose pre-winter filling thresholds, with different targets depending on the facilities. The federal regulator generally sets an 80% level for 1 November, with a specific lower target for sites such as Rehden. The decision to strengthen purchases thus comes within a framework where stock levels and timing are already monitored by public authorities.
Berlin also plans to create a strategic gas reserve from 2027, subject to the necessary legislative changes. The model would draw partly on oil stocks while considering gas’s different characteristics. Storage, ownership, market release rules and participants’ responsibilities must be defined. A public reserve can only be effective with clear governance and a release mechanism suited to crises.
This prospect reflects a changing state role in German energy security. After dependence on Russian imports, Berlin is seeking tools to reduce uncertainty in the event of an external shock. Maintaining public stocks has a cost, however, and can shift risks to public finances or consumers if storage rules are poorly calibrated.
No shortage announced, but a narrower margin
Authorities do not anticipate a supply disruption, even in a harsh winter or with further import disturbances. This assurance rests on all available channels: pipelines, LNG terminals, storage and interconnection capacity with neighbouring countries. It does not eliminate the possibility of higher prices or the need to manage demand during the coldest periods.
Lower stocks also reflect the market’s economic signals. The difference between summer and winter prices may not compensate energy companies for purchase and injection costs. Authorities therefore want to prevent commercial calculations from weakening collective security. The measure’s effectiveness will become clear if reserves reach targets on time without causing excessive price pressure.
The order given to SEFE is thus an indicator of vigilance rather than an announcement of an established crisis. It underlines that energy security rests on a combination of contracts, infrastructure and reserves. Germany must reconcile advance purchases, expanded import capacity and preparations for a strategic reserve while ensuring the cost of this protection remains sustainable for businesses and households.
