Austria will overhaul its photovoltaic subsidy system, ending broad financial support for small solar installations to prioritize battery storage and intelligent energy management. Economy and Energy Minister Wolfgang Hattmannsdorfer announced the shift, citing severe seasonal price swings driven by midday solar production spikes.
The current framework, established under the 2021 Renewable Expansion Act, faces a restructuring as the federal government looks to address grid congestion and plummeting equipment costs.
Summer Surplus and the Growing Need for Storage
The strategic pivot comes in response to extreme market volatility during the summer months. Midday photovoltaic generation frequently creates massive electricity surpluses, while demand peaks in the evening just as solar production drops off.
Data from the Wirtschaftsministerium, highlighted by Kurier, illustrates the structural imbalance. On a recent Saturday with a total consumption of 120.1 gigawatt-hours, Austria generated 117.8 gigawatt-hours, with roughly 30 percent coming from solar. A midday generation peak of 4.3 gigawatts contrasted sharply with an evening load peak of 6.1 gigawatts that arrived with virtually no solar output.
This disconnect translates directly into wholesale pricing extremes. The average wholesale electricity price between 10:00 AM and 4:00 PM settled at 14 euros per megawatt-hour, whereas evening prices surged to approximately 180 euros per megawatt-hour. Minister Wolfgang Hattmannsdorfer emphasized that deploying storage is essential to capture cheap domestic power rather than relying on costly foreign imports after dark.
Economy and Energy Minister Wolfgang Hattmannsdorfer stated that if the country has a surplus of cheap domestic electricity at midday, it must be able to store it for the evening instead of having to buy expensive electricity from abroad later on, adding that their clear goal is to make better use of cheap domestic production and that they need more properly deployed storage systems to achieve this.
A New Framework for Subsidies and Applications
Under the planned reforms, direct financial backing for standard small photovoltaic setups will phase out.
Crucially, the policy eliminates the First come first serve
allocation system, which in past funding calls exhausted available funds within minutes. Moving forward, applications for grants can be submitted after installation and invoicing, mirroring the mechanics of a homeowner craftsman bonus.
Certain specialized applications will retain their subsidy eligibility. Financial support remains in place for building-integrated photovoltaics, agricultural solar installations, parking lot canopies, floating solar arrays, and installations along noise barrier walls. Additionally, a manufacturing bonus will reward buyers who select core components built in Europe.
Subsidizing Retrofits and Adjusting the Transition
Property owners wishing to upgrade existing setups will find the new rules more flexible. Financial incentives will apply directly to the retrofitting of battery storage onto pre-existing solar arrays.
The third and final traditional funding call under the current system is scheduled for October 8, operating under the established rules. State Secretary Elisabeth Zehetner defended the shift by pointing to a roughly 90 percent drop in equipment prices over recent years, arguing that the original 2021 market conditions no longer justify broad direct subsidies for basic hardware.
Industry Response and Regulatory Demands
Industry groups have offered a mixed reception to the announced overhaul. The industrial association Photovoltaic & Battery Austria welcomed the emphasis on storage infrastructure while pressing officials to ensure the transition yields practical, workable realities.
Managing Director of the Federal Photovoltaic & Battery Austria Association Vera Immitzer emphasized that the crucial factor, however, is that the announced storage offensive now translates into concrete measures.
At the same time, government officials are pushing regulatory authorities for complementary adjustments. Minister Hattmannsdorfer called on the energy regulator E-Control to refine criteria for system-supportive storage to prevent overly restrictive guidelines from choking off infrastructure growth. Opposition figures, meanwhile, criticized the announcement as recycled policy proposals already detailed in previous evaluations by the Austrian Energy Agency.
