Austrian local energy storage brand

A study 1 carried out by the University of Applied Sciences Technikum Wien, AEE INTEC, BEST and ENFOS presents the market development of energy storage technologies in Austria for the first time.

The entire storage infrastructure in Austria is owned by OMV AG and RAG, as well as by joint ventures between RAG and astora, Gazprom Export LLC and Uniper Gas Storage GmbH. Owing to the geological conditions, most of the storage facilities are pore storages, since depleted natural gas fields are used for gas storage.

Of these, approx. 94% were built with public funding and 6% without. The total inventory of photovoltaic battery storage systems in Austria therefore rose to 11,908 storage systems with a cumulative usable storage capacity of approx. 121 MWh.

A total of 840 tank water storage systems in primary and secondary networks with a total storage volume of 191,150 m³ were surveyed in Austria. The five largest individual tank water storage systems have volumes of 50,000 m³ (Theiss), 34,500 m³ (Linz), 30,000 m³ (Salzburg), 20,000 m³ (Timelkam) and twice 5,500 m³ (Vienna).

In 2020, Austria had a hystorically grown inventory of hydraulic storage power plants with a gross maximum capacity of 8.8 GW and gross electricity generation of 14.7 TWh. This storage capacity has already played a central role in the past in optimising power plant deployment and grid regulation.
