The Southern Gas Corridor carries Azerbaijani gas some 3,500 km from the Caspian’s Shah Deniz field through Georgia and Türkiye to Italy — Europe’s flagship supply-diversification route. This hub tracks Caucasus Business Journal’s corridor coverage: pipeline expansions, EU supply deals and the push toward 20 bcm.
The Southern Gas Corridor is a ~3,500 km chain of pipelines carrying natural gas from Azerbaijan’s Shah Deniz field in the Caspian Sea to Europe. It links three segments — the South Caucasus Pipeline through Azerbaijan and Georgia, TANAP across Türkiye, and the Trans Adriatic Pipeline (TAP) through Greece and Albania to Italy.
Three connected pipelines form the corridor: the South Caucasus Pipeline (Baku–Tbilisi–Erzurum), the Trans-Anatolian Natural Gas Pipeline (TANAP) across Türkiye, and the Trans Adriatic Pipeline (TAP) from the Greek–Turkish border to Italy.
Azerbaijan exported about 12.5 bcm of gas to Europe in 2025 — up 56% since 2021 — out of roughly 25 bcm of total gas exports. TAP added 1.2 bcm of annual capacity in early 2026, and corridor partners are working toward roughly 20 bcm of deliveries to Europe.
Azerbaijani gas now reaches 16 countries. Italy is the largest European buyer, alongside Greece and Bulgaria, with Türkiye and Georgia supplied along the route — and deliveries to Germany and Austria began in January 2026 after the TAP expansion.
SOCAR and bp lead the Shah Deniz consortium, while TANAP and TAP are run by dedicated consortia including SOCAR, BOTAŞ, bp, Snam, Fluxys, Enagás and Axpo. In 2026, Abu Dhabi’s ADNOC agreed to take a strategic stake in the corridor.
