VNG calls for state intervention on storage refill

German gas importer VNG AG publicly asked the federal government to intervene in storage refill after Reden, the country's largest cavern, recorded only 21 Mmcm of next-season bookings, roughly one two-hundredth of site capacity.

Key takeaway

Reden booked at one two-hundredth of capacity is a market mechanism failure, not a slow start.

VNG AG, one of Germany's largest gas importers, publicly called on the federal government around 1 April 2026 to intervene in storage refill after concluding that injection had become uneconomical at prevailing spreads 1. Reden, Germany's largest gas storage site, had only 21 Mmcm booked for next season, approximately 1/200th of total site capacity 2. LNG deliveries to Germany had fallen from roughly 40 Mmcm/day in late March to 22 Mmcm/day in early April, a 45% reduction 3.

VNG AG is Germany's second-largest gas network operator and importer, based in Leipzig; its call for state intervention is the market reading itself as broken. Reden is the anchor estate of the German storage system and the single largest cavern in the country. A public utility asking a federal government to underwrite private refill economics is not a policy preference, it is the operator saying the mechanism no longer works. The gas storage levy, the main injection-incentive instrument, was abolished on 1 January 2026 with no replacement named. What remains is a spot-to-forward spread that has to fund injection without policy support, and the booking data confirms it does not.

The mechanics compound the politics. Germany was net-withdrawing 459 GWh on 13 April , four days into what should have been injection season. Withdrawal capacity across the German estate runs at roughly 7.0 TWh/day against 4.3 TWh/day of injection capacity, meaning the caverns empty faster than they fill even when the market is working. At current booking rates, the catch-up physics is punishing.

Chancellor Friedrich Merz's coalition signed off a EUR 1.6bn relief package on 13 April 4. The instruments are a 17-cent gasoline tax cut for two months and a EUR 1,000 tax-free employer bonus; the target is the petrol pump, not the cavern. Bruegel has explicitly warned against gas-price subsidies as the policy response, while VNG is asking for exactly that 5. The short-term ban arriving late in the month removes approximately 1.5 bcm per month of potential inbound with no replacement supply named, landing the policy fork inside the same week the storage question sits unresolved.

Deep Analysis

In plain English

Germany has a network of giant underground gas storage sites that the country fills up with gas each summer so it can draw on those reserves during cold winters when demand is highest. The largest of these sites is called Reden. Right now, almost no one has booked space at Reden for next winter because the economics don't work: it costs more to pump gas in than companies can expect to make selling it later. VNG AG, one of Germany's biggest gas importers, has publicly asked the government to step in and fix this problem. Without state help, Germany could head into next winter with its main gas reservoir largely empty.

Deep Analysis
Root Causes

The German gas storage market operates through a capacity-booking mechanism where operators purchase storage slots in forward auctions. The commercial case for booking rests on the summer-winter spread being wide enough to cover injection costs plus capital. When the spread is thin relative to injection economics, operators do not book.

The gas storage levy the main injection-incentive instrument was part of a broader EU-level emergency toolkit introduced after the 2022 shock. Its abolition on 1 January 2026 was a political decision taken in a lower-price environment that has been overtaken by the 2026 supply crisis.

No replacement was named because no political consensus existed for a permanent state subsidy of private injection economics. Germany is now exposed to the consequence: a market mechanism designed for normal price conditions, operating in conditions the mechanism was never calibrated for.

The Reden figure of 21 Mmcm against several thousand Mmcm of total capacity is not a slow start to the booking season; it is a statement that the commercial case for injection does not exist at prevailing spreads. VNG AG's public call is the company publishing its own economic assessment and asking the state to solve the structural problem the abolition created.

What could happen next?
  • Risk

    If Reden booking rates do not recover before June, Germany's anchor storage estate enters July at levels that make 80% November fill mathematically improbable without emergency instrument.

    Short term · 0.85
  • Consequence

    The abolished storage levy's absence has created a precedent where commercial operators will make public state-intervention calls as a negotiating tool, shifting political economy of storage governance.

    Medium term · 0.68
  • Precedent

    State intervention in private storage-injection economics, if it occurs, will set a template for EU-wide storage governance reform ahead of the 2027 regulation review.

Causes and effects
Different Perspectives
Germany
Germany
Germany holds the EU's largest storage estate but entered injection season at 23.32% fill with a 4.3 TWh/day injection ceiling that physically prevents any sprint recovery; the Bundeswirtschaftsministerium has maintained its early warning stage since July 2025. An escalation to Alarmstufe, which would trigger compulsory injection obligations, remains live if storage fails to rise through April.
QatarEnergy
QatarEnergy
QatarEnergy declared force majeure on European LNG contracts citing Ras Laffan strike damage, while the Gulf Research Centre assessed the declaration may also reflect a commercial decision to reallocate volumes toward higher-priced Asian spot markets without triggering breach penalties. Independent engineering confirmation of damage extent has not been published, leaving legal and commercial uncertainty unresolved.
Equinor / Norway
Equinor / Norway
Norway remains the EU's largest pipeline gas supplier and benefits from sustained elevated TTF; Norwegian pipeline capacity has partially offset the Russian supply loss but cannot close the structural gap. Norway Zone 4 power prices at EUR 2/MWh on 13 April illustrate how hydro-dominated systems are structurally decoupled from the gas price shock affecting continental Europe.
Italy
Italy
Italy cleared day-ahead power at EUR 133/MWh on 13 April, four to five times the Iberian equivalent, because gas-fired plants set the marginal price for approximately 90% of generation hours. Italy's circa 40 GW of gas-fired CCGT capacity, built when gas was cheap and nuclear was politically blocked, is now a structural liability at EUR 47/MWh TTF.
Spain
Spain
Spain cleared at EUR 29/MWh on the same day Italy paid EUR 133/MWh, the starkest single-day demonstration that its renewable energy investment is translating directly into price shock insulation for industry. Iberian interconnector constraints at the Pyrenees mean Spain cannot export this advantage to northern European markets at scale.
Japan and South Korea
Japan and South Korea
Japan and South Korea are competing with Europe for the same Atlantic LNG cargoes as Ras Laffan tightens global supply; their long-term contract portfolios provide partial insulation but leave both exposed on spot volumes. Bruegel proposed a trilateral buyer coalition representing 60% of global LNG demand, but Tokyo and Seoul have not formally responded.
