Jänschwalde Power Station is located near the village of Jänschwalde in Brandenburg on the German-Polish border. The lignite-fired power station has an installed capacity of 3,000 megawatts and consists of six 500 MW units. It is the second-largest brown coal power plant in operation in Germany and is owned by Swedish state-owned Vattenfall. ==Overview== The power station was built between 1976 and 1989. Between the German reunification and 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 emission in Europe, according to a study by the WWF.〔http://assets.panda.org/downloads/european_dirty_thirty_may_2007.pdf The ''Dirty Thirty'' report〕 Jänschwalde power station predominantly fires raw brown coal from nearby open-pit mining in Jänschwalde and Cottbus to 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 energy is produced. The yearly power output lies around 22 billion kWh, 22 TWh. The site formerly featured three obsolete 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 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jänschwalde Power Station」の詳細全文を読む スポンサード リンク
