The Bischofshofen community power plant is a run-of-river power plant located on the Salzach and in the municipal district of Bischofshofen in Salzburg. Bischofshofen was the first link in the power plant chain on the Salzach and was built between 1982 and 1985. Two Kaplan turbines generate over 70 GWh annually and supply the region with valuable electricity produced entirely from hydropower.
Turbines and generators: Two Kaplan bulb turbines with a horizontal shaft generate an output of 8,560 kW each with a head of 9.0 metres. The four-blade impellers with a diameter of 3.6 metres have an intake capacity of 111 m³/sec. The two bulb turbine generators have a nominal output of 9,500 kVA. The generators are cooled by means of a closed circuit.
Transformers: Two 9,500 kVA machine transformers raise the generated energy to 30,000 V. Transmission is via a 30 kV line to the medium voltage grid of Salzburg AG. The plant additionally has two 400 kVA transformers to cover its own requirements.
Weir system: In order to control the three-field weir system, welded pressure segments in the box design with weir flaps are used. With a clear width of 10 metres, the gates enable a dammed height of 10.6 metres. The system is power oil-hydraulically by means of Rexroth weir hydraulics.
