Inn River power plants

At approximately 517 kilometres long, the Inn is a major Alpine river in Central Europe that flows through Switzerland, Austria and Germany. It rises at Lago di Livigno in the Swiss Alps and initially flows east before turning north near Innsbruck in Austria.

In the historic city of Innsbruck, which owes its name to the river (“bridge over the Inn River”), the Inn served as an important trade route in the past and continues to dominate the cityscape to this day.

With its numerous hydropower plants, the Inn contributes significantly to energy generation in the region and is thus an important factor in the renewable energy supply. Finally, the Inn flows into the Danube near Passau in Germany and, due to its volume of water and deposits, significantly influences the ecology and the riverbed of the larger river.

Inn River

The Inn River provides reliable, environmentally friendly electricity generation from run-of-river power plants. VERBUND’s power plant chain continuously uses the flow energy and ensures the energy supply and grid stability in the region. Ecological measures – from fish passes to river bank upgrades – are an integral part of operations. On the Inn River, a cross-border Alpine river, renewable energy generation is combined with responsible river basin management.

LIFE Riverscape Lower Inn

With EU support, VERBUND is implementing numerous measures in Bavaria and Upper Austria to promote the environmental development of the river landscape along the Lower Inn. These include near-natural bypass channels at the Inn power plants Braunau-Simbach and Egglfing-Obernberg as well as further creation of aquatic habitats in the power plant areas of the Inn power plants Ering-Frauenstein, Egglfing-Obernberg and Schärding-Neuhaus.

We look from above at the riverbank region near the Ering Frauenstein power plant on the Inn. Fish and river habitats are being created here.

LIFE Blue Belt Danube Inn

With the help of the extensive renaturalisation programme, we are linking the last habitats along the Danube and the Border Inn River that had previously been interrupted. Following on from existing projects, the power plants of Schärding-Neuhaus, Jochenstein, Aschach and Ybbs-Persenbeug will be equipped with fish passes and banks will be restored over a large area. This will make the Danube and the Inn passable for fish from Romania to Rosenheim.
