Azerbaijan's natural gas now reaches 16 buyer countries, placing the country among the world's leading pipeline gas exporters and reinforcing its strategic role in European energy security. The milestone, confirmed by Prime Minister Ali Asadov earlier this month, comes as the Trans Adriatic Pipeline consortium completes a capacity expansion to 11.2 billion cubic meters per year — a key step toward potential further growth along the Southern Gas Corridor.
The Southern Gas Corridor, comprising the South Caucasus Pipeline, the Trans-Anatolian Pipeline (TANAP), and the Trans Adriatic Pipeline (TAP), has been the most strategically significant European pipeline project of the past decade. It has proven its value since the EU began aggressively diversifying away from Russian gas following the 2022 Ukraine war, with Azerbaijani molecules now flowing into Italy, Greece, Bulgaria, Romania, Hungary, and a growing list of Central and Eastern European markets.
Capacity remains a binding constraint on further expansion. TANAP currently has roughly 16 bcm of annual capacity, of which about 6 bcm goes to Türkiye and around 10 bcm transits into TAP. Pushing the system toward 20 bcm of European delivery would require additional compression stations along TANAP, regulatory harmonization between transit countries, and substantial capital investment. According to S&P Global, Turkish officials have signaled readiness to support expansion but want clearer European demand commitments.
Long-term contracts are the central question. Azerbaijani officials have repeatedly warned that without binding multi-year offtake agreements from European buyers, the upstream and midstream investment required to lift volumes will not materialize. Shah Deniz field operator BP and SOCAR are among those calling for clarity from Brussels, particularly given the long lead times for compressor station installation. The Atlantic Council has analyzed the political and commercial obstacles to scaling the corridor.
For European buyers, the value proposition is straightforward. Azerbaijani gas is geographically diversified from Russian routes, supplied under long-term contracts that have proven reliable, and increasingly priced competitively against LNG alternatives. Italy in particular has emerged as the largest TAP offtaker, and Hungary, Croatia, and Romania have followed.
The next milestone will be commercial. If new long-term contracts are signed in 2026 at sufficient volume, the case for compressor station investment becomes self-funding. If not, Azerbaijan's gas growth story risks plateauing at the current capacity ceiling — even as European demand for non-Russian molecules remains robust.
