Nussdorf Run-of-River Plant

Nussdorf power plant is a run-of-river plant situated on the river Inn in the municipality of Nussdorf on Inn.

The Nussdorf power plant was built between 1979 and 1982. Two Kaplan turbines generate an annual average of around 246 GWh of electricity and supply the region with electricity produced entirely from hydropower.

Ecology & environmental protection

The construction of a fish bypass at the Nussdorf am Inn power plant is currently being planned: various construction options are being discussed for optimal implementation of a fish bypass at the location. Initial operation is expected to take place in 2020.

The entire plant group of the Styrian hydropower plants has been awarded the environmental certificate ISO 14001. The power plants on the rivers Mur and Enns not only fulfil the statutory requirements but also focus on high environmental standards and technical innovations. The goal is the efficient use of hydropower and the balance between economy and ecology. The effectiveness and benefit of the environmental management system are mainly the responsibility of our employees, who undergo constant training and development in this area.

Wherever ecologically valuable and technically feasible, VERBUND has set itself the goal of guaranteeing the continuity of flow for domestic fish and aquatic life at the locations of its hydropower plants. By 2025, VERBUND will invest 280 million euros on the implementation of fish bypasses and other ecological structural measures.

Our latest conservation projects
Turbines and generators: The Nußdorf power plant is designed as a pier power plant, with three weir fields and two turbine piers arranged in alternation along the longitudinal axis. Each of the turbine piers houses an Kaplan turbine with vertical shaft and an umbrella generator with a total bottleneck capacity of 48 MW.

Weir system: The weir openings are closed by pressure segment gates with flap; they are operated by oil-hydraulic lift cylinders. The power plant belongs to the “border power plants” group, which is noted for its geographical location on the rivers Inn and Danube, where they form the border between Austria and Bavaria.
