A dispute between Germany and Italy over natural gas storage has exposed tensions within the European Union’s energy market, as wholesale prices approach levels last recorded during the 2022 energy crisis and governments confront the prospect of another expensive winter.

Italy has accused Germany of contributing to the latest surge in European natural gas prices by delaying the replenishment of its underground storage facilities, reopening a debate about national energy policies and their consequences for the EU’s single market.

The dispute emerged on 29 October after the European benchmark gas price briefly exceeded €100 per megawatt hour the previous day, its highest level since December 2022.

Germany’s gas storage facilities were just 61.7 per cent full, compared with almost 91 per cent in Italy and an EU average of approximately 75 per cent.

The difference has become politically sensitive because European countries purchase gas in an interconnected market, meaning decisions taken by one major consumer can influence prices paid elsewhere.

Speaking at the Montel Italian Energy Day conference in Milan, Alessandro Noce, director general for energy markets and infrastructure at Italy’s Energy Ministry, criticised Germany’s approach to preparing for winter.

According to Reuters, Noce argued that Italy had spent €300 million securing additional gas reserves, only to face higher market prices as Germany attempted to replenish its comparatively depleted stocks.

He also questioned whether Germany had delayed purchases because of preparations to privatise energy companies involved in the storage process.

Germany’s Economy Ministry did not immediately respond to the criticism.

Germany’s Storage Decisions Under Scrutiny

The German government’s approach has attracted particular attention because of its role in the operations of Uniper and Securing Energy for Europe (SEFE).

Both companies became important components of Germany’s energy-security arrangements following the disruption of Russian gas supplies in 2022.

Plans concerning their future ownership have coincided with renewed questions about how Berlin balances commercial considerations against the need to maintain strategic reserves.

At the Milan conference, an energy analyst suggested that preparations for privatisation had contributed to delays in storage purchases.

That assessment has not been established as the definitive explanation for Germany’s comparatively low reserves.

Nevertheless, the resulting political dispute demonstrates the difficulties of managing energy security through a system in which national governments retain considerable discretion while their purchasing decisions affect a common market.

Europe’s Gas Market Faces Renewed Pressure

Europe’s latest price increase has several causes extending beyond German storage policies.

Disruptions to liquefied natural gas shipments associated with the conflict involving Iran have constrained supplies from the Middle East.

At the same time, European countries entered the summer storage-refilling period with unusually low reserves following the previous winter.

The EU Agency for the Cooperation of Energy Regulators (ACER) reported that underground gas storage was only 28 per cent full at the end of winter 2025–26.

By 21 October, that figure had risen to 75 per cent, still below historical levels.

In its latest gas-market monitoring report, ACER estimated that disruption linked to the Middle East conflict had added between €18 billion and €33 billion to Europe’s gas-import bill.

The agency also found that American liquefied natural gas accounted for roughly 30 per cent of EU gas supplies, reflecting Europe’s growing reliance on transatlantic energy imports.

Although this diversification has reduced dependence on Russian pipeline gas, it has also increased Europe’s exposure to international competition for LNG cargoes.

European buyers must compete with customers in Asia, particularly when colder weather or geopolitical disruptions increase demand.

EU Storage Rules Face a Test

The disagreement has implications for the European Union’s gas-storage framework.

Following the 2022 energy crisis, the EU introduced mandatory storage requirements intended to reduce the risk of supply shortages during winter.

The arrangements were subsequently extended until the end of 2027.

Under the revised rules, member states retain a 90 per cent storage-filling target but have greater flexibility over when and how it is achieved.

Countries may reach the target between 1 October and 1 December, rather than being bound to the previous 1 November deadline.

Further flexibility is available in difficult market conditions.

These provisions were designed partly to prevent governments from creating artificial demand peaks by purchasing gas simultaneously to meet rigid deadlines.

However, the present dispute suggests that delayed purchases can create another problem if several major consumers need additional supplies as winter approaches.

Germany’s current storage level does not, by itself, establish a breach of EU requirements. The applicable deadlines and permitted exemptions must also be considered.

Italy Seeks Greater Scope for Intervention

The Italian government has meanwhile been seeking permission from the European Commission to use public funds to reduce energy costs for households and businesses.

Rome’s concerns reflect the economic consequences of sustained high gas prices, particularly for industries dependent on energy-intensive manufacturing.

Italy faces a general election expected in 2027, adding a domestic political dimension to the debate over energy subsidies.

Noce warned that prices could rise to between €150 and €180 per megawatt hour if January brings particularly cold weather.

Such an outcome remains a scenario rather than a forecast.

Energy markets will also be influenced by developments in the Middle East, LNG deliveries, industrial demand and winter temperatures.

A European Problem Without a Single National Solution

Europe has expanded its LNG import infrastructure and diversified energy sources substantially since 2022.

However, the latest price increases demonstrate that greater import capacity does not necessarily insulate consumers from global supply disruptions.

The German–Italian dispute also exposes the limits of national energy planning within an integrated European market.

Germany’s storage policies affect its neighbours, just as decisions taken elsewhere influence the price German consumers pay.

The central question for Brussels is whether existing coordination arrangements provide sufficient incentives for governments to safeguard their own winter supplies without transferring additional costs to other member states.

With the heating season approaching, that issue is becoming an immediate economic concern rather than a theoretical dispute about European energy solidarity.

Europe’s electricity market recorded substantial regional differences on Tuesday, 27 October, with average wholesale prices ranging from approximately €6 per megawatt-hour in northern Sweden to more than €255 in Romania.

The figures reveal a persistent difficulty for European energy policy: although the continent has an increasingly interconnected electricity market, businesses and consumers remain exposed to very different underlying wholesale costs depending on location.

According to European day-ahead electricity market data, Sweden’s SE2 bidding zone recorded an average of €6.23 per megawatt-hour, while Finland stood at approximately €6.65. Romania reached €255.20, roughly 41 times northern Sweden’s price. Bulgaria registered approximately €254, Hungary €241 and Greece €225. Germany recorded approximately €155, Belgium €160 and France €162.

These are wholesale prices for delivery on 27 October, not final bills for households or businesses. Their differences nevertheless raise questions about how effectively Europe’s electricity networks distribute power from areas of lower-cost generation to those facing greater costs.

Why a common market produces different prices

European electricity trading is organised through interconnected national and regional markets. Cross-border capacity allows relatively inexpensive power to reach regions where demand is greater or local generation is more expensive.

When transmission capacity is adequate, neighbouring prices can converge. Physical networks, however, have limits. Congested interconnectors can prevent additional imports even when large price differences exist.

Other influences include availability of power stations, renewable output, fuel prices, consumption and system stability. Regions with substantial hydropower, nuclear generation or strong renewable production may experience comparatively low prices. Markets relying on gas-fired generation can be more expensive when gas plants are needed to satisfy the final increment of demand.

The result is a market responding to common European conditions but still shaped by local generation and transmission constraints.

Southeastern Europe’s structural constraints

The European Union Agency for the Cooperation of Energy Regulators, ACER, has repeatedly examined the causes of regional price divergence. In its 2026 assessment of cross-zonal electricity trade, the agency considered unusually high prices and limited access to lower-cost power in southeastern Europe.

Constraints include available cross-border capacity and shortages of flexible generation able to respond to changing renewable output, especially in the evening. Countries including Greece, Bulgaria, Romania, Hungary, Croatia and Slovenia have encountered substantial regional differences.

Those findings do not prove the cause of each price movement on 27 October. They do, however, explain why disparities can persist despite common market rules. ACER has advocated improved coordination among transmission operators, more effective use of existing networks and additional flexibility through storage and demand management.

Industrial consequences of expensive electricity

Energy-intensive industries, including steel, chemicals and fertiliser production, are particularly sensitive to electricity costs. Where contracts are exposed to wholesale markets, sustained regional price differences can influence output and investment decisions.

The relationship between wholesale prices and bills is not immediate. Firms may hedge prices, use long-term contracts or produce their own power. Network charges, taxes and government support also affect the amount paid. Still, persistent market differences can shape industrial competitiveness.

As EU Today reported, EU energy ministers are due to examine proposed changes to electricity network charges and market administration on 29 October. Network tariffs are distinct from wholesale prices, but both affect total electricity costs.

Renewables and the need for flexible networks

According to ACER’s energy-market monitoring, renewable sources represented around half of EU electricity generation in 2025. Solar energy can reduce prices during the day, but output falls sharply towards evening, sometimes requiring more expensive power stations to increase generation.

This increases the value of storage, flexible production, responsive demand and international connections that can balance surpluses and shortages between regions. Yet major transmission lines can take years to complete owing to planning, permitting, investment and construction requirements.

The priority is therefore not simply to install more renewable capacity. Europe’s grids and supporting technologies must be capable of moving and using that output efficiently.

What the price divide reveals

A single day’s wholesale prices should not be mistaken for long-term average electricity costs or a permanent competitive advantage. Nevertheless, the persistence of regional disparities documented by regulators shows the problem extends beyond isolated daily volatility.

For EU institutions, the question is whether further market integration can make energy more affordable while preserving incentives to invest in generation and transmission. National governments must balance security of supply, infrastructure financing and industrial competitiveness.

Electricity trading across Europe is increasingly integrated. The physical systems supplying it remain considerably less uniform. Until those constraints are addressed, the price of power will continue to reflect geography as well as the underlying cost of energy.
