International technology group Andritz has been commissioned by Upper Austrian utility Energie AG to provide electromechanical equipment for the Ebensee pumped storage power plant. This initiative represents both the largest single investment by the energy utility and a stride toward achieving climate neutrality.
Leveraging the area's topography, the pumped storage plant will store excess energy by pumping water from Traunsee lake to a mountain reservoir situated 500m higher at Grosser Sonnstein. Andritz’s role in this venture encompasses the supply of a 170MW variable-speed reversible pump turbine, the generator, and associated automation.
The groundbreaking ceremony for the Ebensee project occurred in October 2023, marking a milestone for Austria's commitment to sustainable energy solutions. With commercial operations slated to commence in 2028, the plant is projected to provide green electricity to approximately 280,000 households.
