The power plant Altenwörth is a Danube - run power plant in the cadastral Altenwörth the Lower Austrian municipality of Kirchberg am Wagram , about 20 kilometers below Krems . The most powerful Austrian Danube power plant was built between 1973 and 1976 and belongs to the Lower Danube plant group .

location

The low-rise construction was carried out to the south, next to the original Danube basin. After completion, the Danube was diverted into the new basin.

The power plant serves as a bridge over the Danube for cyclists and pedestrians.

The system has six weir fields and two locks (each 230 m × 24 m). The reservoir length of the river is around 30 km and the reservoir target is 193.5 m above sea level. A. at river kilometers 1,979.83.

Nine machine sets in the machine house , which was built on the right, southern bank of the Danube, supply electricity to the public grid . Each of these machine sets consists of a Kaplan bulb turbine with a horizontal shaft and a directly coupled three-phase generator . The Kaplan bulb turbines 1 to 3 have a nominal output of 38,700 kW each , the turbines 4 to 6 each generate 39,000 kW and the turbines 7 to 9 have a nominal output of 38,800 kW each. The impeller diameter of 6 m, the nominal speed of 103.4 min ⁻¹ and the nominal flow rate of 300 m³ / s are identical for all nine turbines. The mean raw head is 15 m.

The nine three-phase generators have a nominal voltage of 7,750 volts and a nominal output of 45,000 kilovolt amperes (kVA) each . Overall, the power plant has a bottleneck capacity of 328 MW.

With an expanded flow rate of 2,700 m³ / s, the standard energy capacity is 1,967.6 GWh per year . This power plant thus generates around one sixth of the electricity generated on the Austrian Danube.

Former river basin

An attractive and natural recreation area has been created in the quiet arm of the Danube. A boat harbor was built at the former Traisen estuary. The Kamp flows since the power plant construction in the old Danube basin, formerly it flowed near Krems in the Danube.

Traisen

Since the water level in the reservoir area was raised, the course of the Traisen had to be relocated and the estuary moved to the east. The new course of the river was very much straightened. As part of the Life + Project Traisen , the course is to be made much more curvy and new living spaces are to be left to nature. A new floodplain should be 82 hectares. The estuary will be relocated further east. This should make the Traisen four kilometers longer. According to the official procedures, the "LIFE + Traisen" project should start in 2012 and be completed in 2016. The implementation is carried out by Verbund AG .
