Technical description

Designed as a diversion power plant, the plant uses the head between the channel and the original river bed of around 30 metres, which was required for the most effective use of the Francis turbine available at the time. 
The Jettenbach reservoir dams the Inn 8 km back to the Faulbach confluence 1 km below Gars and leads the water to the power plant along the 20 km-long headrace channel.
The power plant itself consists of a surge chamber, 15 pressure pipes and the powerhouse with 15 Francis front boiler turbines with horizontal shafts. The turbines originally powered eight three-phase generators and seven direct current generators. When the connected aluminium production facility was closed in 1996, six of the seven DC generators were converted to three-phase current and one DC machine set was decommissioned, so that currently only 14 downpipes are supplied with water. Since then, the electrical energy has been fed into the regional 110 kV grid.
