Schwarze Pumpe power station
F2
Under the name Schwarze Pumpe power plant is now a 1993-1998 built and operated by Vattenfall Europe lignite -fired power plant, consisting of two power plant units understood with a capacity of 800 MW each. It is located on the site of the Schwarze Pumpe industrial park. On this site since 1955 there have been several, no longer existing power plants. In 2006 was begun south of the large-scale power plant to build a pilot plant for CO2 sequestration, which was put into operation on September 9, 2008.

Gas Schwarze Pumpe (1955-1997)
As part of the construction of the gas VEB Kombinat Schwarze Pumpe also three power plants with the name Schwarze Pumpe power plant West, Central and East were put into operation at the site of today's industrial parks. The first power plant unit delivered from 1959 electric power and process steam. The block services amounted to between 25 and 100 MW. With the end of the gas combine the associated power plants were shut down and demolished between 1990 and 1997.
Vattenfall's Schwarze Pumpe power plant ( from 1992)
The coal-fired power plant Schwarze Pumpe was designed and built ( Espag ) as a joint venture power plant Schwarze of the then independent companies VEAG and power plants pump AG. The corresponding contract was signed on 13 February 1992 and in March of the same year the design contract for a power plant to Siemens was granted.
Important facts
On 15 March 1993, the official opening of the construction site was " new power plant Schwarze Pumpe ". On 20 April 1993, the necessary permits under the Federal Emission Control Act were issued. The foundation stone was laid on 25 October 1993 by the Brandenburg Prime Minister Manfred Stolpe. On 1 January 1995, VEAG took over the shares in the power plant of the Lusatian mining management company ( LBV).
During the construction phase took place on March 25, 1995 to a serious accident. From an assembly crane dissolved in 160 m height 6 counterweights and plunged into the depths. This incident caused damage to both the boiler frame of block A as well as on the bottom plate.
On 28 June 1996 was already the pressure test on the boiler block A, only one was to complain of 60,000 welds. The pressure test on the boiler block B on December 14, 1996, it shall without any complaints. On 16 April 1997, the first coal wagon was unloaded with raw lignite from the Welzow -south. Took place on 19 April in 1997 at the steam generator block A, the first firing with oil fire, on May 3, the initial coal fire until May 23, when at 20:01 clock the first network circuit of the block A was performed.
On 1 October 1997, the new power plant Schwarze Pumpe officially took over the district heating supply for the city Spremberg, from 14 October 1997 was also the supply of Hoyerswerda with district heating.
Then took place on 29 October 1997 at 17:07 clock also on block B, the first network circuit. On 15 January 1998, the block B achieved an output of 800 megawatts for the first time. On January 20, 1998, the new Schwarze Pumpe power plant reached its design capacity of 1,600 megawatts for the first time.
On 3 June 1998, the official commissioning of the new power plant Schwarze Pumpe took place. Among the guests were former Chancellor Helmut Kohl and former Minister President of Brandenburg, Manfred Stolpe.
On August 25, 1998, the new power plant Schwarze Pumpe by the Board of VEAG was handed over to the management of the power plant Schwarze Pumpe. First power plant manager was Dietrich Kirmse.
Planned and built, a 2 × 800 -megawatt dual-unit plant for base load operation on the basis of raw lignite. The raw lignite required is taken from the neighboring Welzow -south.
In addition to generating electrical energy includes the provision of process steam for businesses in the nearby Schwarze Pumpe industrial park as well as the supply of the place Schwarze Pumpe and cities Spremberg and Hoyerswerda with district among its main tasks. The Schwarze Pumpe power plant belongs, with its roughly 360 employees to one of the largest employers in the region.

Emissions
Power plant Critics at Schwarze Pumpe power plant occurring 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. On published by the WWF in May 2007 List of klimaschädlichsten power plants in the EU ranked the Schwarze Pumpe power plant, according to its installed capacity in 2006 to 14th in Europe and ranked 7th in Germany (1000 g CO2 per kilowatt hour) after the power plants Niederaußem, Jaenschwalde, Frimmersdorf, Weisweiler, Neurath and Boxberg.
The Schwarze Pumpe power plant reported the following emissions in the EU pollutant registers " PRTR "
Other typical pollutant emissions were not reported because they are reportable from a minimum annual amount in the PRTR only, eg Fine dust than 100 kg, 50 kg nickel, chromium than 100 kg, lead and zinc from 200 kg inorganic fluorine compounds from 5.000 kg ammonia from 10.000 kg volatile organic compounds except methane (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. Then Schwarze Pumpe power plant is ranked 20 of the damage costs of all European industrial plants.
Pilot plant for CO2 capture
On the site of the industrial park Schwarze Pumpe, Vattenfall Europe has built a pilot plant for CO2 capture using the oxyfuel process in close proximity to the Schwarze Pumpe power plant.
The water formed in the combustion of coal, carbon dioxide is condensed and liquefied. It should then be compressed and stored in the ground, and thus do not contribute to global warming. On 29 May 2006, the groundbreaking ceremony was attended by German Chancellor Angela Merkel and Matthias Platzeck, Minister President of Brandenburg, instead. On 12 December 2007, the boiler pressure test of the experimental plant was held in which there were no complaints. End of March 2008, work began successively to the test operation of the plant. The official commissioning of the plant took place on 9 September 2008 by Matthias Platzeck and the Vattenfall CEO Lars Josefsson.
The Vattenfall pilot plant is fired with lignite and has a thermal power of 30 MW. It does not generate electricity, but indirectly provides process steam for installations in Schwarze Pumpe industrial park available. The construction cost of the plant was around 70 million euros.
Large-scale plant for CO2 capture
With the results and lessons learned in the pilot plant, an existing power plant boiler with a thermal output of 640 MW should (250 MW electrical ) will be replaced from 2015 by a new building with the oxyfuel process in the power plant Jaenschwalde. From the European Energy Programme for Recovery this facility had been promoted with EUR 180 million. With this power plant, the technology used here should be led to large-scale series production. On December 5, 2011, Vattenfall Germany boss Tuomo Hatakka in Cottbus announce the official outing for CCS demonstration project in Jaenschwalde. The CCS pilot plant in Schwarze Pumpe is not affected by this exit and continue.
Others
From environmentalists the plant as a " fig leaf " of the energy group is called and criticized for being too expensive. According to their opinion could be with the same money by investing in more efficient energy production and use have a greater impact on reducing global warming reach.
Per Provisional available by the Berlin Regional Court of 5 December 2007, it is Vattenfall Europe prohibited the oxyfuel pilot plant at Schwarze Pumpe continue "the world's first pilot plant for CO2-free ( brown coal) power plant " and / or " the world's first research facility for a CO2-free ( brown coal) power station to call. " Offenses, however, are punishable by fine or order administrative detention. The plaintiff was a photovoltaic operator from Berlin.
After a trial before the District Court of Berlin in March 2008, the injunction on the use of the term "CO2 - free power plant " has been considerably limited but not yet lifted in their use. Vattenfall should therefore only use the term when it is declared at the same time, it just does not come to a 100 percent deposit of the waste carbon dioxide from the power plant process and that the resulting carbon dioxide for the safe transportation and subsequent disposal needs to be treated.
