Ecology & environmental protection

A fish bypass at the Passau-Ingling run-of-river power plant is currently being planned.

The plant group of the border power plants was certified under ISO 14001 for the first time at the end of 2017. The power plants on the rivers Inn and Danube in the border area between Austria and Germany not only fulfil the statutory requirements but also focus on high environmental standards and technical innovations. Goals include the efficient use of hydropower and a 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 in the implementation of fish bypasses and other ecological structural measures.

Our latest conservation projects
Turbines and generators: Four Kaplan turbines with vertical shaft and a maximum output of 96 MW are combined with four directly coupled three-phase synchronous generators with a nominal output of 27 MVA.

Transformers: The electricity generated is raised from 10.5 kV to 110 kV by means of four high-voltage main transformers and fed into the grid via the open-air switchgear to 110 kV lines on the Austrian side and two on the Bavarian side.

Weir system: Five weir fields with a clear width of 23 metres each are equipped with double hook gates with a closing height of 14.2 metres each. The gates are operated by weir chains powered by electric motors and mechanical gearboxes with oil-bath lubrication.
