Hydroelectric barrages along the Mur River, Styria, Austria

No more barrages! Hydroelectric power plants along the Mur River in Graz, Austria, provoke strong mobilizations by local citizens groups


The Mur River passing through the city of Graz, Austria, has turned into a contested area characterized by ongoing conflicts between local citizens group and the renewable energy industry. Already in the past, plenty of hydroelectric barrages were constructed along the river. The currently planned construction of another series of 5 middle-sized hydroelectric barrages would further drastically reduce - over a distance of 130km - the remaining free flowing sections to distances of no more than 5km, while negatively affecting local ecosystems, citizens as well as recreational areas [1].

Project Details and Actors
Project DetailsA series of 5 new hydroelectric barrages are planned along the Mur River in Styria, located between the cities Leoben and Spielfeld [1]. Two of them are already constructed; “Kraftwerk (KW) Gössendorf -18,75MW and KW Kalsdorf - 18,5MW (near to completion). The involved companies Verbund AG and Energie Steiermark AG started project planning at least in August 2005 or before [2].

Investment size for KW Gössendorf and KW Kalsdorf was reported to amount to over 160 million € [1]. During 2013, investment value was lost by at least 18 million € [7], if not up to 36 million euro [1]. Responsible for the loss in economic value was probably the too optimistic expectations regarding production and the currently large electricity supply in the EU [1].

Before construction, KW Gössendorf was expected to produce electricity amounting to 155 million KWh/year [2]. After construction, production was reported to amount to 90 million KWh/year [5].

With a coverage of 1,414ha, the riparian forests surrounding KW Gössendorf and KW Kalsdorf were among the largest of its ecological type (“Hartauwald”) within Austria [1]. The barrages irreversibly changed their ecological characteristics. 80ha were completed cleared [1]. Up to 20,000 large and medium trees were felled [6], many of them protected [see pictures].

Environmental ImpactsVisible: Biodiversity loss (wildlife, agro-diversity), Loss of landscape/aesthetic degradation, Deforestation and loss of vegetation cover, Reduced ecological / hydrological connectivity
Potential: Air pollution, Surface water pollution / Decreasing water (physico-chemical, biological) quality, Groundwater pollution or depletion, Large-scale disturbance of hydro and geological systems
Socio-economic ImpactsVisible: Land dispossession, Loss of landscape/sense of place
Project StatusIn operation
Pathways for conflict outcome / responseCourt decision (failure for environmental justice)
Strengthening of participation
Development of AlternativesThe central proposal of the local citizen group "Rettet die Mur" is to oppose and stop the further construction of the hydroelectric barrages.
Do you consider this as a success?No
Why? Explain briefly.Two barrages are already constructed and changed significantly local ecosystems.
