The pipeline is intended to bring 31 Bcm/a of natural gas from the Caspian region, Middle East and Egypt to Central and Western European gas markets via Eastern Europe, reducing dependency on gas from Russia.

The pipeline will be approximately 3,300 km in length, starting at the Turkish border of either Georgia or Iran, and lead to Baumgarten in Austria. Gas will then be further transported to Central and Western Europe through Austria.

Already ratified by Bulgaria and Hungary, the project now awaits legislative approval from Austria and Romania.
