Austria Commercial Energy Storage Power Station

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 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.

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).

Activated components and buildings are usually heated and/or cooled with heat pump systems. As of 2015, heat pumps in Austria have been equipped with a corresponding smart grid interface. In total, this amounted to approx. 121,200 buildings at the end of 2020 with a maximum load shift potential of approx. 0.43 GWhel per hour of shifting time.

For 2020, a price of around € 914 per kWh of usable storage capacity excl. VAT was charged for PV storage systems installed as turnkey solutions. This means a price reduction of approx. 9.6% on the previous year 2019.
