The Schwarzbach power plant is a small hydropower plant located in Thuringia , Vorarlberg , Austria , on the Malerina plot, below the Montjola waterfall, and the only power plant on the Schwarzbach.
history
The possibility of using the water and the height of fall of the Schwarzbach in a small space gave u. a. the decisive factor for founding a textile factory below the Montjola waterfall. The Montjola ponds were created for the equal use of water power. On May 7, 1832, the businessman Peter Kennedy, who worked in Feldkirch, acquired Johann Martin Winkler's smithy in Thuringia, which also included the Montjola waterfall. Construction of the factory began in 1835. A spinning and weaving mill was built by John Douglass and Partners, which was run by John Douglass from 1837 to 1863. In 1909 the company was sold to Rudolf Kastner and his brother Paul.
In 1909, the so-called “large turbine”, which is now a showpiece next to the new power house of the power plant, was installed in the factory below. It is a Francis turbine with an output of 420 hp (308.91 kW ) at 1000 revolutions per minute. The turbine was in operation almost continuously until 1967. It was produced by the Rüsch works in Dornbirn . The Kastner textile company closed its operations on December 31, 1968, after 132 years, and the power plant was shut down. Part of the old, above-ground pressure pipeline can still be seen today next to the waterfall path.
In 1974 the area was auctioned and bought by the municipality of Thuringia.
The projection phase and preparation time for the construction and commissioning of the power plant lasted about ten years. The construction time took three months. Thuringia has been an e5 municipality since 2002 and wants to make a contribution to Vorarlberg's energy autonomy with the Schwarzbach small hydropower plant.
On October 14, 2004, the revitalization of the power plant was tried for the first time with a building negotiation, but failed because of the rejection by two landowners. In 2011, with the consent of the landowners, a new administrative procedure could then be initiated and on January 10, 2014 the approval notice was available. The symbolic start of construction took place on July 25, 2014 with the groundbreaking ceremony in the presence of Environment Minister Andrä Rupprechter . The small hydropower plant has been feeding in energy since November 24, 2014.
Power house
Power house new
The power house, in which the turbine , the generator and the control of the Schwarzbach power plant are located, is located in a specially constructed building (4 × 5 m floor area). A total of around one million euros was invested in the small hydropower plant. These costs should be amortized in around 15 years .
The municipality of Thuringia is responsible for maintaining the Schwarzbach small power station.
Electrotechnical data
The generator is a three-phase synchronous machine with a maximum output of 220 kW at 400 V (320 A ) at 600 rpm.
Hydraulic data
The water for the Schwarzbach power plant is taken from the Schwarzbach and previously stored in the Montjola ponds . The Schwarzbach flows through the communities of Thuringia and Bludesch . The catchment area of the Schwarzbach, which rises from the Montiola springs, is 7.2 km² and another 3.0 km² is drained into the Montjola ponds via the Schlosstobel pipeline.
The water is drawn off at 682 m above sea level. A. via an intake structure with fully automatic Coanda computing. The water reaches the power house via an underground 185 m long pressure pipeline made of nodular cast iron with an inner diameter of 40 cm and a maximum flow rate of 300 liters per second and then, after processing, via a four-nozzle Pelton turbine with a maximum output of 200 kW 600 revolutions per minute, almost immediately after the power house back in the Schwarzbach. The turbine blade wheel weighs around 300 kg. The nominal head is 75.2 m.
environmental Protection
To protect the Montjola waterfall, the power plant may only be operated when more than 90 liters of water per second is available. The consensus water quantity is 300 liters per second, more water must not be taken for energy production.
