Ecology & environmental protection

The construction of a fish bypass is currently being planned.

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 powerhouse contains two double controllable, almost horizontally installed bulb turbines (9° inclination). With an impeller diameter of 3.85 metres each, they have a maximum output of 20,200 kW and an average annual output of 86 million kWh. The two three-phase synchronous generators have a nominal output of 11,400 kVA.

Transformers: The energy is transmitted via two 11,400 kVA block transformers installed next to the power plant access way in Boxen, which raise the generated electricity from 5 kV to 20 kV. From there, the energy is transmitted further via an underground cable duct to the switch house of Steiermärkische Elektrizitäts-AG (STEG), which is located in the old powerhouse.

Weir system: Three 6.8 metre-high segment gates with a 2.5 metre-high flap regulate the discharge of flood water. Each of the 15.5 metre-wide segments is controlled by two push cylinders arranged on both sides, while each of the flaps is operated by a centrally arranged push cylinder.
