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.
With the study “Stromspeicher 2050” by Vienna University of Technology on behalf of the Climate & Energy Fund, a first-ever analysis was performed of how the demand for electricity storage will develop in the Austrian and German electricity system up to 2030 and 2050 as the share of renewables in power generation increases.
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.
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.
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).
Innovative storage technologies and new fields of application for the use of energy storage systems are being researched and demonstrated in practical operations as part of national and international research and development activities.
