TAP Capacity Expands 12% as Azerbaijan Cements Role as Europe's Gas Security Anchor

The Trans Adriatic Pipeline (TAP) — the European terminal link of Azerbaijan's Southern Gas Corridor — increased its operational capacity by 12% at the start of 2026, enabling an additional 1.2 billion cubic meters of Azerbaijani and Central Asian natural gas per year to reach EU markets. The expansion extends the pipeline's reach further into Southern European energy markets, with gas now flowing to Austria and Germany for the first time since the pipeline network's completion.
The capacity increase is a direct result of operational optimizations and compression upgrades agreed between TAP's operator consortium and European network administrators. It coincides with record Southern Gas Corridor throughput: Azerbaijan and SOCAR supplied 12.5 billion cubic meters of natural gas to EU member states in 2025, a 53.8% increase over 2021 delivery levels, according to the joint statement issued at the March 3 EU-Azerbaijan ministerial meeting. Bulgaria has become one of the most dependent recipients, with Azerbaijan supplying approximately 40% of the country's gas consumption — a figure that illustrates how deeply Southeast European energy security has become structurally linked to Azerbaijani export reliability.
The TAP capacity expansion is part of a broader Southern Gas Corridor Advisory Council process through which the EU, Azerbaijan, and transit partner countries periodically review and agree on technical and commercial enhancements to maximize the system's contribution to European supply diversification. At the 12th Ministerial Meeting, EU Commissioner Dan Jørgensen reaffirmed the crucial role of the SGC as a transmission system delivering Azerbaijani gas to an increasing number of customers. According to Trend.az, Kazakhstan has also increased oil shipments via the Baku-Tbilisi-Ceyhan pipeline by 8.5% in February 2026, underscoring how the SGC infrastructure system serves not only Azerbaijani but also Central Asian export interests.
Over the longer term, the same pipeline corridors and grid interconnectors that carry natural gas are being positioned to also carry electrons — the Black Sea Submarine Cable and the planned green energy corridor linking Central Asia to Europe via Azerbaijan are explicitly designed to use the institutional and physical infrastructure of the Southern Gas Corridor as their backbone.
For European energy policy stakeholders and investors, TAP's expanding capacity and Azerbaijan's demonstrated reliability as a supplier — operating the SGC without interruption for five consecutive years — provide a strong foundation for deepening investment in the Caspian energy system. Eurasianet has analyzed how Europe's accelerated energy diversification since 2022 has permanently elevated Azerbaijan's strategic importance to the continent's energy security architecture.
