The Schkopau power plant is a German lignite power plant near the Korbetha district of the Schkopau municipality in the Saale district (Saxony-Anhalt). It has two power plant units that went into operation in 1995 and 1996 respectively. The electrical efficiency is 40%. The chimney of the Schkopau power plant is 200 meters high.
The power station itself is 58.1% owned by Uniper SE subsidiaries . The other 41.9% belonged to NRGenerating German Holdings GmbH ( Teufen , Switzerland) through Saale Energie GmbH (Schkopau ). The operating company of the power plant was divided similarly: 55.6% belong to Uniper, 44.4% to Saale Energie GmbH. In 2012 the Czech energy supplier EP Energy as took over the 41.9 percent stake from NRGeneration German Holdings GmbH. On February 21, 2020 it was announced that Uniper would sell its majority stake of 58% to a subsidiary of the Czech EPH Group in October 2021.
The shutdown of the two units is planned for December 31, 2034.
Technology and operation
The two turbine-generators to produce electrical energy for the public needs in principle for a power output of 450 megawatts designed, but are nominally operated with a rated power of 418.7 MW (block A) and 387.3 MW (block B) . The additional amount of steam generated in the boilers is used in an additional turbo set with an output of 110 MW to generate traction current ( single-phase alternating current with a frequency of 16.7 Hertz ) for Deutsche Bahn AG . The power plant also extracts steam for the chemical industry (in cogeneration ). The lignite required to operate the power plant is obtained from MIBRAG , which extracts it in the opencast mines in the Zeitz area (especially from the Profen opencast mine ).
The power plant is connected to the Lauchstädt substation via a high-voltage line, where it feeds into 50Hertz Transmission's 380 kV transmission network .
Environmental and health damage
Critics point to high emissions of the power plant Schkopau nitrogen oxides , sulfur oxides , mercury and particulate matter on which cancer producing substances ( lead , cadmium , nickel , PAHs , dioxins and furans ) can adhere. A study commissioned by Greenpeace at the University of Stuttgart in 2013 came to the conclusion that the fine dusts emitted by the Schkopau power plant in 2010 and the secondary fine dusts formed from sulfur dioxide, nitrogen oxide and NMVOC emissions statistically lead to 817 years of life lost. The Schkopau power plant therefore ranks 10th on the list of “Germany's most health-damaging coal-fired power plants”.
In addition, in view of climate change, the power plant's CO 2 emissions are being criticized, which are particularly high in lignite-fired power plants per kilowatt hour of electricity generated.
The Schkopau power plant reported the following emissions in the European pollutant register " PRTR ":
| Air pollutant | 2007 | 2010 | 2011 | 2012 | 2013 |
|---|---|---|---|---|---|
| Carbon dioxide (CO 2 ) | 5,570,000,000 kg | 5,120,000,000 kg | 5,500,000,000 kg | 5,620,000,000 kg | 5,670,000,000 kg |
| Sulfur dioxide (as SO x / SO 2 ) | 3,390,000 kg | 4,770,000 kg | 4,410,000 kg | 7,180,000 kg | 7,760,000 kg |
| Nitrogen oxides ( NO x / NO 2 ) | 3,390,000 kg | 3,320,000 kg | 3,720,000 kg | 3,610,000 kg | 3,670,000 kg |
| Carbon monoxide ( CO ) | 667,000 kg | 600,000 kg | 603,000 kg | not specified | not specified |
| Particulate matter ( PM10 ) | 152,000 kg | 74,600 kg | 105,000 kg | 77,500 kg | 69,400 kg |
| Inorganic Chlorine Compounds (as HCl ) | 17,300 kg | 16,200 kg | 17,300 kg | 17,400 kg | 17,500 kg |
| Inorganic fluorine compounds (as HF ) | 9,290 kg | 8,640 kg | 9,260 kg | 17,400 kg | 9,310 kg |
| Mercury and compounds (as Hg ) | 189 kg | 227 kg | 345 kg | 441 kg | 430 kg |
| Nickel and compounds (as Ni ) | 139 kg | 129 kg | 137 kg | 137 kg | 138 kg |
No other typical pollutant emissions were reported, as they are only required to be reported in the PRTR from an annual minimum amount, e.g. B. Dioxins and furans from 0.0001 kg, cadmium from 10 kg, arsenic from 20 kg, copper and chromium from 100 kg, lead and zinc from 200 kg, ammonia , nitrous oxide (N 2 O) from 10,000 kg, volatile organic compounds except methane (NMVOC) from 100,000 kg and carbon monoxide from 500,000 kg.
The European Environment Agency has estimated the cost of damage to the environment and health of the 28,000 largest industrial plants in Europe on the basis of the emission data reported in the PRTR using the scientific methods of the European Commission. According to this, the Schkopau power plant ranks 39th among the damage costs of all European industrial plants.
| cause | Damage costs | unit | proportion of |
|---|---|---|---|
| Schkopau power plant | 314-507 | Million Euros | 0.3-0.5% |
| A total of 28,000 systems | 102-169 | billion euro | 100% |
