RAG gas storage facilities

RAG operates its underground gas storages facilities in Salzburg and Upper Austria. These facilities are porous sandstone reservoirs of large volume, which are connected to the Austrian and German pipeline network. Storage capacities are offered to the market by RAG's subsidiary RAG Energy Storage.

Puchkirchen/Haag gas storage facility

RAG made its first gas discovery in Puchkirchen in 1956. Conversion of the gas formation into a storage reservoir began in 1982 and was completed in 2009 after a number of expansions. During the summer of the latter year the Puchkirchen facility was linked with the Haag reservoir. At present the facility has a maximum working gas volume of some 1.1 bn cu m (equivalent to 12.5 TWh), and injection and withdrawal capacity of 520,000 cu m/hour (6 gigawatts, GW).


Haidach 5 gas storage facility

The repurposing of this depleted gas formation as a storage reservoir began in 2005. Haidach 5 has a maximum working gas volume of around 16 mn cu m (equivalent to 185 GWh), and injection and withdrawal capacity of approx. 20,000 cu m/hour (231 megawatts, MW).


Aigelsbrunn gas storage facility

Gas production at this field started in 2001. Development of the gas storage facility began in 2008, and it was commissioned on 1 April 2011. Aigelsbrunn has a max. working gas volume of approx. 130 mn cu m (equivalent to 1.5 TWh), and injection and withdrawal capacity of 50,000 cu m/hour (577 MW).
