Europe’s Energy Shift: Spain and Algeria in Advanced Talks to Boost Medgaz Gas Supplies

Introduction: A Race for Stable Energy

As tensions escalate across the Middle East, Europe is once again scrambling to secure its energy lifelines. For Spain—and increasingly for other European nations—Algeria has emerged as a critical partner. The two countries are now in advanced talks to increase gas supplies through the Medgaz pipeline, a subsea link that directly connects Algeria to Spain, with a potential boost of up to 10 per cent in flows .

The negotiations come at a time of renewed volatility in global energy markets. Conflicts in the Middle East have raised fears of supply disruptions, pushing European buyers to seek more stable sources closer to home . For Algeria, the renewed demand presents an opportunity to strengthen its position as a strategic supplier to Europe.

This ASJ article examines the significance of the proposed Medgaz increase, the broader context of Europe’s energy diversification efforts, and the implications for both North African gas exporters and European energy security.

The Medgaz Pipeline: A Critical Link

Infrastructure and Capacity

The Medgaz pipeline is a subsea natural gas pipeline that runs from Beni Saf in Algeria to Almería in Spain, traversing the Mediterranean Sea. With a length of approximately 210 kilometres, it is one of the key infrastructure links connecting North African gas reserves to European markets .

The pipeline currently has spare capacity of roughly 1 billion cubic metres (bcm) annually , which could accommodate the proposed increase of up to 10 per cent in flows.

Strategic Importance

Medgaz is one of several pipelines carrying Algerian gas to Europe, alongside the GME pipeline (via Morocco) and the Trans-Mediterranean Pipeline (via Tunisia to Italy). However, Medgaz has gained particular importance in recent years due to:

• Direct connection: It bypasses Morocco, avoiding political complications

• Reliability: The pipeline has a strong operational record

• Capacity: It provides a substantial volume of gas directly to the Iberian Peninsula

The Negotiations: What’s on the Table?

Talks Nearing Agreement

Two people familiar with the discussions told Reuters that the negotiations between Spain and Algeria were nearing a preliminary agreement , which could be reached during Spanish Foreign Minister José Manuel Albares’ visit to Algiers this week .

Speaking after meeting Algerian President Abdelmadjid Tebboune and senior officials, Mr Albares confirmed that discussions on higher volumes were underway, pointing to ongoing volatility in global gas markets:

“We have talked about there being a greater volume (of gas). We spoke about the context of the gas market with the war in the Middle East” .

Proposed Increase

The proposed increase would rely on spare capacity in the Medgaz pipeline, allowing for an additional 1 bcm of gas annually —roughly a 10 per cent boost over current flows .

The Algerian Connection

Algeria already plays a critical role in Spain’s energy mix. Data from Spain’s gas grid operator Enagás shows Algerian gas accounted for more than 29 per cent of Spain’s imports in the first two months of 2026, making it one of Madrid’s top suppliers .

Commercial ties between the two countries remain strong. Spanish utility Naturgy holds long-term contracts with Algeria’s state energy firm Sonatrach for around 5 bcm of gas annually . Sonatrach also owns a majority stake in the Medgaz pipeline and a minority share in Naturgy, underscoring the depth of the relationship .

The Broader Context: Europe’s Energy Scramble

Middle East Tensions Reshape Supply Routes

The negotiations come against a backdrop of heightened geopolitical risk. Iran-linked tensions in the Middle East have added fresh uncertainty to supply routes, pushing buyers to seek more stable sources closer to home .

The crisis has disrupted key shipping lanes, with major carriers suspending operations through the Strait of Hormuz and vessels rerouting around the Cape of Good Hope . While much attention has focused on the impact on oil and gold shipments, natural gas markets are also feeling the pressure.

Diversification Away from Russian Gas

Since Russia’s invasion of Ukraine, Europe has worked aggressively to reduce its dependence on Russian gas. Algeria has emerged as one of the continent’s key alternative suppliers, alongside Norway, the United States, and Azerbaijan.

Competition for North African Gas

Other European countries are also turning to Algeria. Italian Prime Minister Giorgia Meloni said during a visit to Algiers this week that Rome is seeking additional gas supplies , highlighting growing competition for North African energy .

Italy already receives Algerian gas via the Trans-Mediterranean Pipeline (Enrico Mattei), which runs through Tunisia. Any increase in Algerian exports to Spain could have ripple effects across the Mediterranean market, potentially tightening supply for other buyers .

The Algerian Perspective: Strengthening Strategic Position

A Strategic Supplier

For Algeria, the renewed demand from European buyers presents an opportunity to strengthen its position as a strategic supplier to Europe . The country has long been a major gas producer, but its role has grown in significance as Europe seeks to diversify away from Russian supplies.

Investment and Capacity

Algeria has been investing in its gas infrastructure to maintain and expand export capacity. Sonatrach, the state energy company, has announced plans to increase exploration and production, aiming to meet growing domestic and international demand .

Geopolitical Leverage

The renewed European interest in Algerian gas also gives Algiers greater geopolitical leverage. As Europe scrambles for stable energy supplies, Algeria’s role as a reliable partner enhances its diplomatic standing and bargaining power .

The Spanish Perspective: Securing Energy Stability

A Critical Partner

For Spain, Algeria is a critical energy partner. The country relies on Algerian gas to meet a substantial portion of its energy needs, and any disruption would have significant economic consequences .

Avoiding Past Tensions

The relationship has not always been smooth. In 2022, diplomatic tensions briefly threatened gas supplies after Spain shifted its stance on Western Sahara, prompting Algeria to threaten to suspend the friendship treaty and reconsider gas exports . Those tensions were eventually resolved, and the current negotiations signal a return to pragmatic cooperation.

Building Resilience

By increasing Medgaz flows, Spain aims to build resilience against potential supply shocks. The additional volumes would help cushion the impact of any disruptions in other supply routes—whether from Middle East tensions, LNG market volatility, or unforeseen outages .

Global Implications: A Shift in Energy Geopolitics

The Enduring Importance of Pipeline Gas

The renewed focus on Medgaz highlights the enduring importance of pipeline gas in Europe’s energy mix. While liquefied natural gas (LNG) has grown in importance, pipelines offer several advantages:

• Reliability: Fixed infrastructure provides predictable flows

• Cost: Pipeline gas is often cheaper than LNG

• Geopolitical stability: Long-term contracts provide mutual benefits for both producers and consumers

North Africa’s Rising Role

North Africa is increasingly central to Europe’s energy security. Algeria, in particular, is well-positioned to supply gas to southern Europe via existing pipelines. Libya and Egypt also have potential to contribute, though political instability and infrastructure challenges remain constraints.

Competition for Resources

As more European countries seek Algerian gas, competition for available supplies is likely to intensify. Italy’s overtures to Algiers during the same week as Spain’s negotiations underscore this dynamic. The outcome will depend on Algeria’s production capacity, investment levels, and strategic priorities .
