In July 2026, the Austrian Ministry of Economy commissioned a study to identify sites for new run‑of‑river and pumped‑storage hydropower plants and to streamline licensing procedures, such as environmental impact assessments and water‑rights approvals. The initiative aims to add approximately five terawatt‑hours of hydropower by 2030 to reduce reliance on gas-fired generation and electricity imports. 

Regional authorities in Tirol and Styria introduced complementary plans. Tirol reported that renewable sources supplied 60% of its final energy use in 2024 and set targets to increase electricity’s share of final consumption to 47% and bioenergy to 18% by 2050. In Styria, authorities moved to redesignate priority zones as "fast-track" areas to accelerate solar capacity toward a 3,300 MW target by 2030, though industry groups cautioned that many sites lack sufficient sunlight or grid connections. Styria is also advancing wind power expansion, including the transport of large rotor blades to the Freiländeralm wind farm.

However, by August 2026, severe drought conditions began impacting hydroelectric production. Low water levels in rivers have significantly reduced output at various plants; for instance, the Obermarkt municipal plant reported production at only 10% to 42% of its average capacity, while TIWAG reported decreases of 12% to 15% at its Kirchbichl and Langkampfen plants. These shortages have necessitated electricity purchases from external providers to maintain municipal supply stability.

## Timeline

### 2026-08-08: Renewable energy developments and drought challenges in Austria

Renewable energy in Austria faces dual realities: wind power expansion is progressing in Styria, while drought severely reduces hydroelectric output in regions like Imst.
