The Donaustadt power plant in Primavesigasse in the 22nd district of Donaustadt was a caloric power plant for the City of Vienna (Block 1 and Block 2). Plans also included the possible construction of a nuclear power plant. Currently (2018) only Unit 3 is in operation, which is designed as a combined cycle power plant with district heating extraction.

history

The shutdown of the Engerthstrasse steam power plant in 1966, the limited amount of cooling water for the Simmering power plant due to the water flow in the Danube Canal and the city council's desire to increase its own electricity generation made it necessary to build a new power plant.

A location in the west of Vienna would have been desirable, but for technical reasons - especially the lack of cooling water - this could not be realized. On November 22, 1968, the Vienna City Council decided in principle to build two new power plant blocks and on July 11, 1969, approval was given to build the new power plant on Steinsporn. After its location in the Donaustadt, the 22nd district of Vienna, the new power station was named " Donaustadt Steam Power Plant ".

Spoken for the choice of location

  • the secure supply of cooling water due to the proximity to the Danube ,
  • the proximity to the Lobau oil port , which would facilitate the supply of heating oil or natural gas ,
  • the strong increase in population as well as the settlement of industrial companies in the districts of Floridsdorf and Donaustadt and
  • the desire to decentralize electricity generation in Vienna.

As a positive side effect, especially from the district politics, the draining of a swamp and the rehabilitation of nearby wild settlements by the construction of roads, canals, electricity and water lines were seen.

Initial plans envisaged the construction of three power plant blocks. The first was to go into operation in 1973 and the second in 1976. The third power plant unit was scheduled to go into operation in 1979. For this block, the responsible authorities kept the option of building it as a nuclear power plant. This was made dependent on further developments in the nuclear energy sector . As recently as February 1974, those responsible held on to this option. It was planned that Vienna would participate in the construction of the planned second Austrian nuclear power plant, which was scheduled to go into operation in 1980 or 1981, with 160 megawatts, but in the event that its output should be too low, the possible construction would continue its own nuclear power plant. It is not known whether the plans for a Donaustadt nuclear power plant were terminated by the referendum on the Zwentendorf nuclear power plant or whether they were canceled earlier.

Power plant units 1 and 2

Since the construction of two power plant blocks was planned, the 150 meter high chimney was designed so that it could accommodate the flue gas pipes of both blocks. Each of the two blocks can be operated with either crude oil or natural gas - natural gas, however, is mainly used - and has a maximum output of 162 megawatts.

Mayor Leopold Gratz opened Block 1 on September 24, 1973, and Block 2 went into operation on September 26, 1973.

For environmental reasons, the boiler furnaces were converted to low-nitrogen oxide burners between 1985 and 1986 . The installation of flue gas filters based on the SCR principle for each boiler was also aimed at reducing nitrogen oxides . With the subsequent installation of nitrogen oxide-reducing systems both during the incineration itself and after the incineration, the Donaustadt steam power plant was a pioneer in Austria with a financial expenditure of around ATS 461 million. The flue gas filters were put into operation in Unit 1 in November 1987 and in Unit 2 on July 1, 1988.

Power plant unit 1 was decommissioned in 2009, power plant unit 2 in 1999 due to high maintenance costs and low efficiency.

Block 3

Unit 3 went into operation in November 2001. It is a combined cycle gas and steam power plant ; designed with gas turbine and condensation extraction steam turbine, which is arranged on a shaft with the generator. Natural gas is used as fuel, and it is possible to retrofit it with extra-light heating oil. The power plant has a nominal electrical output of 383 MW and a parallel district heating output of a maximum of 250 MW.

The construction of Unit 3 of the Donaustadt power plant (" Donaustadt 3 ") was decided by the Vienna City Council on June 26, 1996. In December 1997, Wien Energie submitted the project for Unit 3 of the Donaustadt power plant as the first of its kind and on this scale for an environmental impact assessment . 23 expert groups, the Vienna Environmental Ombudsman and representatives of the 23 communities bordering Vienna were involved in this process. On June 18, 1999, the building was approved by the Vienna provincial government by means of a notice.

The foundation stone for Unit 3 was laid in December 1999. The Donaustadt power plant was officially commissioned on November 30, 2001.

Power plant unit 3 can supply around 385,000 households with electrical energy and 73,000 households with district heating on average . Cogeneration achieves an efficiency including district heating of around 86%, without cogeneration around 58%.

Combined heat and power

On May 30, 2000, the tunnel was opened for the main district heating transport line " Steinsporn I " for the cogeneration of block 3 . This approximately 3.6 km long and 520 million schillings expensive structure crosses, among other things, the Danube Canal, the Danube and the relief channel .

Photovoltaic system

On May 4, 2012, a photovoltaic system with 2040 panels with a total of 500 kW ( watt peak ) on an area of ​​approx. 8000 m² was put into operation on the power plant site .

Donauinsel wind power plant

In 1997, Wien Energie built a wind power research facility consisting of a wind turbine near the Steinsporn Bridge on the Danube Island north of the pumping station of the Left Danube collecting canal . The system is controlled and the data is collected by a computer system in the nearby Donaustadt power station. The power plant is also used to connect the wind turbine to the electrical grid .
