- Jänschwalde Power Station
Jänschwalde Power Station is located near the village of
Jänschwaldein Brandenburgon the German-Polish border. The lignite-fired power stationhas an installed capacity of 3,000 megawatts and consists of six 500 MW units. It is the largest brown coal power plantin operaition in Germany and is owned by Vattenfall.
The power station was built between 1976 and 1989. Between the
German reunificationand the mid-1990s, modern environmental technology was adopted, making higher efficiency possible. Despite this, the power station has the fifth-lowest ratio of energy efficiency to CO2 emissionin Europe, according to a study by the WWF.

Jänschwalde power station predominantly fires raw brown coal from nearby
open-pit miningin Jänschwalde and Cottbusto the north. At full load the power station burns approximately 80,000 tons of brown coal a day. From one kilogram of brown coal about one kilowatt-hour of electrical energyis produced.
The site formerly featured three obsolete m to ft|300 chimneys. These were gradually dismantled in a complex process between 2002 and 2007, as conventional demolition was not possible on the site for space reasons. A unique procedure was introduced for this task: the chimneys were broken down from the top to a height of m to ft|50 by a special mechanism equipped with excavators which works round the edges of the chimneys, after which the remaining stacks are being demolished by conventional means.
