The CHP Wolfsburg West is in cogeneration powered heating plant in Wolfsburg with two identical blocks and a thermal input of 750 MW. Each block generates a maximum of 150 MW of electricity (without heat extraction) or, in the case of combined heat and power, a maximum of 130 MW of electricity and 120 MW of heat. The power plant supplies the Volkswagen plant in Wolfsburg with electrical energy and heat; the city of Wolfsburg is also connected to the district heating network.
history
At the beginning of the 1980s, it was foreseeable that the Wolfsburg North / South thermal power station , which had been in operation since 1939, would no longer be sufficient for the increased energy demand. Construction of the Wolfsburg West thermal power station in the north of the VW site began in 1983; in 1984 and 1985 it was put into operation in two stages. In 1988 a flue gas desulphurization system was installed, and a denitrification system was added in the early 1990s . From 1993 onwards, in addition to hard coal, heating oil and waste oil, it was also possible to burn varnish granulates, and since 2008 sewage sludge granulates from municipal waste water. The dust filter systems (now bag filters ) have also been upgraded to reduce emissions.
Architecture and use
The combined heat and power plant belongs to the VW subsidiary VW Kraftwerk GmbH and consists of two identical blocks. In the west there is a 95 meter high natural draft cooling tower, which was built from concrete, in the east a 140 meter high chimney, also made of concrete. Hard coal is predominantly burned. About 45 tons of coal can be burned per hour and block. 30,000 tons of waste oil and 4,200 tons of sewage sludge granulate may be burned with each year, but the quantities used are significantly lower.
The power plant is used to supply energy to the Volkswagen factory in Wolfsburg and to supply district heating to the city of Wolfsburg. According to a just-in-time concept, the hard coal is regularly delivered by block trains from the Ruhr area or as imported coal from seaports . Every year around 450 trains with 2,000 tons of coal each run to the Wolfsburg North and West thermal power stations.
Planning
In 2018, VW Kraftwerk GmbH announced that the two units 10 and 20 would be exchanged for two gas and steam turbine systems by 2021. No more waste should then be incinerated. The maximum thermal output is expected to drop from just under 760 MW to 676 or 658 MW. To this end, a 30-kilometer gas pipeline is to be built from Walle to Wolfsburg.
