The Potsdam thermal power station is a natural gas powered thermal power station . It is located in Potsdam ( Brandenburg ). In addition to electricity , it produces district heating in a combined heat and power system . In total, two gas-and-steam units produce an electrical output of 84 MW and a thermal output of 275 MW. It produces around 90% of the city's electricity and 95% of the district heating needs.
history
Until 1994 Potsdam was supplied by the coal-fired thermal power station North. In autumn 1993, Mayor Horst Gramlich decided to build a new gas-fired power plant. Thousands of coal miners from the Lusatian lignite mining area protested against it. The town hall was besieged by them and its entrance walled up by the miners. There were vigils with torches. However, the gas power plant was built. In addition to environmental reasons, this was also due to the investment costs, as these would have been twice as high for a coal-fired power station . The power plant was put into operation in 1995 after two years of planning and construction. The construction costs amounted to 180 million marks. The construction has reduced CO 2 emissions by 75 percent.
Renovation work was carried out on power plant unit 1 in 2007. In 2011, the gas turbine in Unit 2 was replaced after 16 years of operation or 128,000 hours of operation. It was replaced by a Siemens turbine of the same type with higher efficiency. In August 2011, Block 2 went back into operation after ten weeks of renovation. In the course of this, the computer system was overhauled.
Technology and operation
Together with the Zeppelinstrasse heating plant , it supplies the residents of Potsdam with district heating via a 160 km long distribution network. The electricity is fed into the power grid via a 110 kV line. The power plant is operated by Energie und Wasser Potsdam GmbH (EWP) , a subsidiary of Stadtwerke Potsdam .
Alternatively, heat can be generated with a power-to-heat system in the form of an electrode boiler.
Heat storage
The power plant has a heat storage system, which can store almost 1.2 GWh with around 41,000 m³ of warm water . This is enough to supply the city with heat for 60 hours. The tank is 48 m high and has a diameter of 36 m. Thanks to the heat accumulator, the thermal power station can operate economically. In this way, the two blocks can be switched off on summer weekends. During this time, the households are supplied with heat from the storage tank. The heat storage system is expected to save 10,000 tons of CO 2 emissions annually. The investment costs are estimated at just under 12 million euros. Of this, 2.2 million euros come from a citizens' fund. The plant has been in operation since November 2015.
