Austria is on track to exceed its target of generating 11TWh of electricity from solar photovoltaic (PV) sources well before 2030, driven by rapid capacity growth and strong policy support, according to a new report from market intelligence firm GlobalData.
The report, Austria Power Market Trends and Analysis by Capacity, Generation, Transmission, Distribution, Regulations, Key Players and Forecast to 2035, highlights the significant expansion of Austria’s solar PV market in recent years. In 2023, the country added approximately 2.5GW of new solar PV capacity, bringing the cumulative installed total to around 6.2GW. By the end of 2025, installed solar capacity had risen further to nearly 9.9GW.
According to GlobalData, this pace of deployment places Austria comfortably ahead of the trajectory required to achieve its solar generation goals before the end of the decade.
The company forecasts that Austria’s solar PV capacity will reach approximately 17.3GW by 2030, while electricity generation from solar installations is expected to increase to around 16.3TWh by the same year.
GlobalData expects Austria to continue adding roughly 1.4GW of new solar PV capacity annually between 2026 and 2030. However, the report notes that achieving the country’s broader renewable energy ambitions will require faster rooftop solar deployment, streamlined permitting procedures, grid upgrades, and greater integration of energy storage and sector coupling solutions to manage midday generation peaks and ensure system stability.
“Strong legal mandates, especially through the Erneuerbaren-Ausbau-Gesetz (EAG), are driving Austria’s solar boom,” said Sudeshna Sarmah, Power Analyst at GlobalData.
According to Sarmah, investment grants, “Made in Europe” bonuses and support schemes for rooftop and open-space PV projects have improved project economics, while declining PV module and system component costs have further strengthened the competitiveness of solar energy.
She also highlighted the growing role of distributed and rooftop solar systems, which benefit from simpler siting and permitting processes. When combined with battery storage, these systems can provide additional flexibility and better match daytime electricity demand patterns.
GlobalData also pointed to the importance of Austria’s OeMAG Marktpreis scheme, which encourages developers to align production and investment decisions with market signals. The mechanism rewards efficient project design, favourable siting and effective grid integration, while offering greater predictability for smaller producers and reducing reliance on fixed feed-in tariffs.
In addition, the report states that the Marktprämie scheme and competitive auctions have helped strengthen investor confidence and lower solar generation costs through market competition, contributing to further growth in the sector.
Looking at investment trends, GlobalData said Austria’s power sector is undergoing a sustained shift towards renewable energy sources, with solar PV playing a central role.
“Between 2020 and 2030, Austria’s investment in its power sector is expected to see a clear and sustained realignment toward renewables, with solar PV as the linchpin of that transformation,” Sarmah said.
Solar PV investment reached a peak of nearly $4.4 billion in 2023 during the 2020–2025 period before moderating in 2025. Nevertheless, GlobalData expects solar PV to remain the leading renewable energy investment segment between 2026 and 2030.
The report also notes that Austria introduced a zero-rate value-added tax (VAT) for small PV installations and associated storage systems between January 2024 and March 2025. Although the measure was removed for new contracts in early 2025, GlobalData said the temporary incentive significantly reduced upfront costs and improved investment returns during a critical growth phase for the sector.
According to Sarmah, Austria’s combination of market-based remuneration mechanisms, operational support schemes, direct investment subsidies, regional value incentives, storage integration measures and favourable tax policies has created a comprehensive framework for solar development.
“These policies have been central to Austria’s surge in solar PV investment and its trajectory toward 100% renewable electricity by 2030,” she concluded.
