With the flick of a switch, Austria has become home to its largest battery installation, marking a significant milestone in the nation's energy storage capabilities.
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.
Approximately 3,500 residential battery energy storage systems (BESS) in Austria were accelerated by an investment grant launched in 2018 at the federal level to kick-start the technology. There are also regional incentives available for both small-scale solar and battery storage in Austria.
For the midterm, battery storage will therefore primarily improve grid stability in Germany – at least to the extent that these storage systems are tailored to grid needs and not to the optimization of solar power consumption in households. Younicos is thus focusing on the market for ancillary grid services (frequency response), not arbitrage.
