The Weissenegg small power plant was constructed at the same time as the Mellach stage on the Mur and the Mellach district heating power plant. Construction works started in 1982 and were completed in 1985. A Kaplan S-turbine generates an annual average of around 6 GWh of electricity.

Ecology & environmental protection

A fish bypass for the Weissenegg power plant 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 S-turbine has a nominal output of 800 kW at a maximum flow rate of 12 m³ per second. It is connected via a shaft to a 1,000 kVA generator which has a nominal voltage of 0.4 kV.

To raise the generated energy from 0.4 kV to 20 kV, there is a 1,000 kVA block transformer next to the machine hall. Transmission is via a 20 kV open-air line to the Hereschwerke in Wildon
