The Wallsee–Mitterkirchen Danube Power Plant is an impressive example of modern engineering along the Danube. It was built between 1965 and 1968 and is one of the largest run-of-river power plants in Austria. With its six Kaplan turbines, it has an installed capacity of approximately 210 megawatts and generates approximately 1.34 billion kilowatt hours of environmentally friendly electricity annually – enough to supply more than one million people. The power plant spans the Danube between Wallsee in Lower Austria and Mitterkirchen in Upper Austria. Its clear, functional architecture blends harmoniously into the expansive river landscape.
The plant plays a central role in Austria's energy supply and also represents the sustainable use of the Danube as an energy source. The power plant will be comprehensively modernized by 2030, further increasing its performance and efficiency. As a technical landmark of the region, it impressively combines nature, water, and energy generation.
