Our porous rock gas storage site 7Fields is located in Austria in close proximity to the German border. This underground storage facility is formed of several former gas reservoirs in Upper Austria and Salzburg. This project has been implemented in several stages between 2009 and 2014. Today, 7Fields connects in a unique way the German NCG market area with the Austrian CEGH market area, reaching both, the distribution grid in Zagling as well as the transmission system in Überackern. This seasonal porous storage facility enhances the gas availability in Germany and Austria. Furthermore, during the cold winter months it ensures security of supply.

7Fields is a joint venture project of Uniper Energy Storage and the Austrian RAG (Rohölaufsuchungs-Aktiengesellschaft). In this project RAG is planner, constructor and technical operator. Its storage capacities are marketed by Uniper Energy Storage in Germany as well as in Austria.
