In Upper Austria, not only the expansion of photovoltaics (PV), but also storage solutions is progressing. There are already more than 20,000 PV electricity storage systems, and the trend is increasing, as State Energy Councilor Markus Achleitner announced in a press release this week.
One reason for this is technology development and market growth, which would lead to falling costs. In addition, electricity storage would offer the opportunity to increase the share of self-consumption of your own PV system and thus permanently reduce electricity costs. In addition, the power grids would be relieved. “Storage solutions are an important component of the energy transition,” said Achleitner.
In 2022, the increase in new electricity storage systems amounted to 4,000 systems with a capacity of 65 megawatt hours (MWh). In 2023, more than 14,000 units with 221 MWh were added.
Sales tax is waived
Upper Austria is also a leader in a comparison of federal states: in 2023 there were 14,609 subsidized PV storage systems with a usable capacity of 220,852 kilowatt hours (kWh). This is followed by Styria (10,231 storage, 159,958 kWh), Lower Austria (11,693 storage, 152,907 kWh), Carinthia (9,745 storage, 118,644 kWh), Salzburg (2,395 storage, 33,640 kWh), Burgenland (1,757 storage, 20,817 kWh), and Tyrol (1476 storage units, 19,012 kWh), Vienna (1579 storage units, 16,257 kWh) and Vorarlberg (695 storage units, 10,703 kWh).

There was also a recent conference of the Upper Austria. Energy saving association took place on the topic: Here information was provided about solutions for private individuals, companies and municipalities.
As reported, since the beginning of the year there has been no sales tax on the purchase of PV systems with an output of up to 35 kWp and the associated storage systems. No further applications are necessary. This exemption also applies in 2025 and also applies to balcony power plants. For systems for which the tax exemption does not apply because they are too large or are installed on company buildings, an application can still be submitted to the OeMAG funding calls via the Renewable Energy Expansion Act.
