Jänschwalde Power Station

F2

The power plant Jaenschwalde is a thermal power plant in the southeast of Brandenburg, which is mainly fired with brown coal from the Lower Lusatian opencast Cottbus -Nord, Jaenschwalde and Welzow -south. Power plant operators, the Vattenfall Europe belonging to Vattenfall Europe Generation AG, which emerged in 2002 from VEAG.

The power plant site is located in the district of the former fortress town of Peitz, about five kilometers southeast of the city center and east of the Peitzer ponds. The eponymous place Jaenschwalde is located approximately four kilometers northeast of the power plant.

In terms of installed capacity, the power plant Jaenschwalde with 3,000 megawatts by the power plants Neurath and Niederaußem the third largest power plant in Germany. In Lusatia the Boxberg power plant with 3,520 MW was only bigger, until its outdated power plant units ( 2,520 MW) were shut down.

According to Vattenfall power plant produces about 22,000 GWh of electricity annually.

Design and Specifications

The lignite-fired power plant was mainly in the hands by the VEB BMK coal and energy, 1976-1988. The power plant consists of six 500 MW units, each with two boilers, each two blocks form a unit. Each of the three units originally had a 300 -meter-high chimney for flue gas emission. After German reunification until the mid- nineties equipment for desulfurization of flue gases have been retrofitted so that a further operation was possible. Since the exhaust gases produced by the addition of lime plaster from the addition of sulfur dioxide, which is processed in the adjacent Lafarge plant or stored on the slag heap of the mine Jaenschwalde. The cleaned flue gases are discharged since then over the nine cooling towers ( three per unit) in the environment.

In the power plant Jaenschwalde raw lignite (a 4-6 million t / ) is mainly from the nearby opencast Jaenschwalde (about 14 million t / a, approximately 11 million in future t / a) and Cottbus-Nord converted into electricity. An increasing percentage (8-11 million t / a) is also supplied through the coal train connection from the Welzow -south. Per day, the power plant at full load requires about 80,000 tons of lignite. Here, about one kilowatt -hour of electricity is generated from one kilogram of brown coal. In 2004, the Müllmitverbrennung was approved up to an amount of 400,000 tons per year by zoning.

According to the operator of the power plant Jaenschwalde reached today a net efficiency 35-36 percent. With an annual output of 23.7 million tonnes of CO2 (2006), it is ranked 7 in the world rankings of the power plants with the most emissions within the European Union in 3rd place when emissions per kWh is the case here with 1.2 kg of CO2 ( after the power plant Niederaußem ) at No. 4 Although the power plant Jaenschwalde is the youngest of the three remaining power plant sites in Lusatia, it has the average oldest technique despite exercise. As part of the Vattenfall applied for but not yet approved development of the coal field Jaenschwalde north, which would ensure the continued operation for about two decades, the power plant should therefore be modernized.

The power is supplied via the switchgear Preilack on the 380 kV high- voltage level in the power grid of the transmission system operator 50 Hertz Transmission.

Demolition of the chimneys

Since an explosion of space has not been possible, the three 300 m high, is no longer necessary due to the renovation work of the 1990s chimneys were torn from the end of 2002 in an elaborate process. The last chimney was demolished in November 2007. Here, a worldwide unique method was used, the chimneys were removed down to 50 m height from a specific equipped with excavators demolition equipment. The remaining 50 m were canceled conventional.

Power plant in the summer of 2004, the first chimney already demolished

Future planning

A continuation of the power plant site after 2020 to be secured by the digestion of new opencast lignite mines in Lusatia after plans of the Vattenfall Group, to which the mining Jaenschwalde North counts. For this, three villages in the municipality Schenkendöbern dredged ( Grabko, Kerkwitz, Atterwasch ) and the population to be resettled.

Likewise, another power plant unit was provided at the site, in which the carbon dioxide produced by the combustion of lignite should be pressed and deposited underground. These plans were set in December 2011.

Emissions of pollutants and greenhouse gases

Power plant Critics at the power plant Jaenschwalde the high emissions of nitrogen oxides, sulfur oxides, mercury and particulate matter, generating from the cancer substances (nickel, cadmium, PAHs, dioxins and furans) may be present.

Moreover, in view of climate change are the CO2 emissions in the criticism. Lignite-fired power plants have the highest carbon dioxide emissions per kilowatt hour, which is why environmental and climate activists criticize as being particularly inefficient and harmful to the climate. On published by the WWF in 2007 List of klimaschädlichsten power plants in the EU the power plant Jaenschwalde ranked in 2006 ranked 4th in Europe and together with the power plant Niederaußem ranked 1st in Germany (1200 g CO2 per kilowatt hour). In absolute terms, the power plant has Jaenschwalde after the power station Belchatow (Poland ) and the power plant Niederaußem the third highest carbon dioxide emissions in Europe.

The power plant Jaenschwalde reported the following pollutant emissions in the European Register " PRTR "

Other typical pollutant emissions were not reported because they are reportable from a minimum annual amount in the PRTR only, eg Cadmium from 10 kg, chromium than 100 kg, 200 kg from zinc, fluorine and inorganic fluorine compounds from 5.000 kg ammonia from 10.000 kg NMVOC of 100,000 kg.

The European Environment Agency has estimated the cost of the environment and human health of the 28,000 largest industrial facilities in Europe based on the reported in the PRTR emissions data with the scientific methods of the European Commission. After the power plant Jaenschwalde caused the third highest damage costs of all European industrial plants.

According to calculations by the University of Stuttgart about a death is determined by the emissions of the power plant caused daily (plus secondary health effects of climate change ), this is the record in Germany.
