Project Details

• Owner: Trans Austria Gasleitung GmbH
• Current capacity: 44.3 billion cubic meters per year
• Length: 383 kilometers
• Status: Operating
• Start Year: 1974

History

Since 1974 natural gas is flowing through the TAG pipeline and the system has been continuously expanded since then. In 1988 TAG II was commissioned and the TAG Loop 2 was put into operation in order to increase the transmission capacity.

Background

The 383-km TAG delivers Russian gas south from the Baumgarten gas hub to Arnoldstein on the border between Austria and Italy. The Trans Austrian gas pipeline supplies Austria, as well as Croatia, Italy and Slovenia. TAG is owned and operated by Austrian transmission system operator Trans Austria Gasleitung GmbH. The pipeline maintains a capacity of 44.3bn cu m/year, and is the largest gas pipeline in Austria.

The Italian company Snam S.p.A. has a share of 84,47% and the Austrian company Gas Connect Austria GmbH has a share of 15,53% in the Trans Austria Gasleitung GmbH.

Incidents

In December 2017, an explosion and fire that erupted at Austria’s main gas pipeline in Baumgarten in eastern killed one person and injured 21 others, prompting Italy to declare a state of emergency as flows from the strategic site were cut off for most of the day.
