In 1997, Rohöl-Aufsuchungs Aktiengesellschaft (RAG) discovered the Haidach gas reservoir holding a total gas in place of 4.3 billion cubic meters (bcm). [2] 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. [3] Construction works started in 2005. [2] The gas storage started officially operating on 24 May 2007. [1]
Haidach underground gas storage uses depleted Haidach porous sandstone gas reservoir at a depth of 1,600 metres (5,200 ft). [2] 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. [1] 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). [2]
The construction of the first stage cost €250 millions. [1]
Haidach gas storage is a joint project of RAG, [4] Wingas and Gazprom Export. It is operated by Austrian energy company EVN. [1]
