Haidach gas storage is an underground natural gas storage in the town of Haidach near Salzburg, Austria. It is the second largest gas storage facility in Central Europe.



In 1997, Rohöl-Aufsuchungs Aktiengesellschaft (RAG) discovered the Haidach gas reservoir holding a total gas in place of 4.3 billion cubic meters (bcm). After depletion of the reservoir, it was planned to convert into a gas storage. The contract for use of the Haidach reservoir as a storage for natural gas was signed between RAG, Wingas and Gazprom Export on 13 May 2005. Construction works started in 2005. The gas storage started officially operating on 24 May 2007.

Technical features

Haidach underground gas storage uses depleted Haidach porous sandstone gas reservoir at a depth of 1,600 metres (5,200 ft). The operating capacity of the gas storage in the first phase is 1.2 bcm. In April 2011, after completing the second phase, the operating capacity would be doubled. The gas storage is connected to the Austrian and German gas grids at Burghausen/Überackern through the 39 kilometres (24 mi) long Austria-Bavaria gas pipeline (ABG).

The construction of the first stage cost €250 millions.


Haidach gas storage is a joint project of RAG, Wingas and Gazprom Export. It is operated by Austrian energy company EVN.
