The power of the Mur has been used to generate electricity for more than 100 years. The Pernegg run-of-river power plant, situated to the south-east of Bruck an der Mur, commenced operations in 1927. The power plant was then put back into use in 2013 after an extended construction phase forming one of the biggest power plant modernisations in Austria (plant replacement). Since then, it has been not only the most powerful of the entire Styrian group of 41 power plants but also the central control room, the “nerve centre” of all Styrian power plants owned and operated by VERBUND. The power plants are coordinated and monitored with maximum precision and competence. Decisive steps are taken here in the event of disruptions or emergencies, such as floods.

Ecology & environmental protection

In addition to the technical upgrades carried out between 2010 and 2013, extensive ecological measures were also taken around the power plant: for example, seven near-natural islands with an area of 2,500 m2 were heaped up in the reservoir at the Zlatten weir and the banks of the headwater channel filled with rock. These measures offer new habitats for juvenile fish. In addition, the residual water flow of the Mur in the area of the power plant was increased. 
The fish bypass at Pernegg power plant, which was built in 1996, was also improved in the form of a near-natural pond pass as part of the modernisation project. The existing ponds and ditches were connected to form a side channel in order to create additional habitat. The fish bypass is 350 metres long and bridges a height difference of 11.7 metres between the reservoir and the water below the weir.
