The Garsten-St. Ulrich is a run-of-river power plant in the state of Upper Austria , Austria . It is located on the Enns in the area of the municipality of St. Ulrich bei Steyr in the area of a former loop of the Enns. The city of Steyr is located around two kilometers north of the power plant. The Rosenau power plant is located about three kilometers upstream .

Construction of the power plant began in the summer of 1965. The first machine in the power plant went into operation on November 3, 1967. The power plant is owned by Ennskraftwerke AG and is also operated by Ennskraftwerke AG.

history

The plans for a hydropower plant in the area of the municipality of Garsten go back to shortly after the First World War . In 1919 a projected diversion power plant of the Upper Austrian Hydropower and Electricity AG (OWEAG) received a permit under water law; but the project was not implemented. In 1939, the Reichswerke AG for ore mining and ironworks Hermann Göring Linz planned a diversion power plant, but this was also not implemented. From 1960 onwards, Ennskraftwerke AG worked on developing the power plant project. The project received approval under water law from the Ministry of Agriculture and Forestry in 1964. Construction work then began in the summer of 1965 with the construction of the excavation pit.

Barrier structure

The barrier structure consists of a weir on the left and a power house (length 50 m, width 48.2 m, height 36.5 m) on the right side of the river. The weir system has three weir fields, each 14 m wide and 12.8 m high.

Reservoir

The barrier dams the Enns into a small reservoir .

power plant

The Garsten-St. Ulrich has an installed capacity of 35.3 (or 38) MW . The average annual generation is 157 (or 162.5) million kWh . The maximum height of fall for the volume of developed water is 13.3 m. The flow rate is 286 m³ / s for all turbines.

The two Kaplan turbines each have a maximum output of 15.5 MW and the associated generators 19 MVA . The turbines were supplied by Andritz and Escher Wyss , the generators by ELIN and Wiener Starkstromwerke GmbH . The first machine went online in November 1967 and the second in January 1968. In the switchgear , the generator voltage is increased to 110 kV by means of a machine transformer. A four-kilometer 110-kV line leads from the switchgear to the Steyr substation .

In addition to the two main engines, a smaller residual water turbine with an output of 1.943 MW is installed. The associated generator has a nominal apparent power of 2.35 MVA.

The power plant has been remote-controlled from the headquarters of Ennskraftwerke AG in the city of Steyr since 2000. Between 2009 and 2011 the impeller was renewed.
