The Buschhaus power plant is a German lignite power plant in the Helmstedt district in the south of Helmstedt . It has a gross output of 392 (net 352) megawatts and is operated by Helmstedter Revier GmbH . The power plant ceased regular operation at the end of September 2016 and has served as a hidden reserve ever since. Complete shutdown should follow in 2020.
description
The operating company Helmstedter Revier GmbH for the power plant and the Schöningen opencast mine was re-established in September 2013 before E.ON Kraftwerke GmbH sold the power plant to MIBRAG , which is owned by the Czech EP Energy as . In 2002 the power plant was modernized. It produced 2.2 million tons of CO 2 annually ; this corresponds to 1200 g CO 2 per generated kWh . The Buschhaus power plant was thus one of the 30 coal-fired power plants with the largest absolute CO 2 emissions in Germany. For the reporting year 2010, the European pollutant emission register for the Buschhaus power plant showed emissions of 2.21 million tons of CO 2 , 1780 tons of sulfur oxides , 1380 tons of nitrogen oxides and 81.3 kg of mercury . It is located in the immediate vicinity of the Helmstedt waste recycling plant .
The operators of the Buschhaus power plant planned to run until 2030. Mathematically, however, the deposits in the Schöningen opencast mine would have been exhausted 15 years earlier, which is why the power plant was to be supplied with coal from the Central German mining district. 6000 tons of lignite per day would have had to be delivered by train to meet the demand, which equates to around 240 freight cars. Due to the transfer to the security standby, the coal-fired power generation ended roughly as originally planned. According to the decision of the MIBRAG supervisory board at the instigation of the Federal Ministry of Economics to meet the federal government's climate protection goals, the power plant should be on standby for four years from October 1, 2016 at the latest and then shut down. In the run-up to the shutdown, coal production in the Schöningen opencast mine was stopped on August 30, 2016. The stored coal should be sufficient for the Buschhaus power plant to operate until the planned shutdown date at most, but it was already running low on September 23, 2016, whereupon the power plant was shut down prematurely.
history
The name Buschhaus goes back to a house near Büddenstedt , which the ducal brown coal mines had built for their miners in 1863 and which was given the name Buschhaus . In 1972 it had to give way to the opencast mine and was demolished. In 1977 a spatial planning procedure began for the construction of a new power plant, the location of which was chosen near the former Buschhaus. On May 8, 1979, the Supervisory Board of Braunschweigische Kohlen-Bergwerke AG decided to name the new power plant after the old name Buschhaus .
The power plant was planned in the late 1970s and should be operated with the sulphurous salt coal from the area. A new open-cast mine , the Schöningen open-cast mine , was specially excavated for the required amount . The operator at that time Braunschweigische Kohlen-Bergwerke (BKB) relied on the CDU-led Lower Saxony state government and refused to install a flue gas desulphurisation system as not being state of the art. There the insight into the installation of the flue gas desulphurisation system only slowly gained acceptance. According to the state government, retrofitting would only have been possible after the Buschhaus power plant had gone into operation. During this time there were several protests by environmentalists. In 1980, the construction of the power plant began, which the West German media often referred to as the “largest polluter in the nation”.
Due to the strong political pressure, the new federal government of Kohl advocated the commissioning of Buschhaus two years later, in order to then start operations with a desulphurisation plant. So she stood against the Lower Saxony state government of Ernst Albrecht . In a special session of the Bundestag called by the SPD on July 31, 1984, to which the MPs were called from vacation, the politicians decided on a compromise: Buschhaus was allowed to go online, but without a flue gas desulphurization system, it would not burn the sulphurous salt coal, but instead use low-sulfur types of coal other mines. Due to further legal disputes, commissioning was postponed until March 1985. The power plant went online on July 30, 1985.
In the Federal Republic of Germany, this was one of the first decisions in which the environmental protection idea was strongly incorporated.
Chimney, cooling water supply and mains connection
The power plant has a 307 meter high chimney , which was the highest in operation in Germany until the power plant was shut down in September 2016.
The power plant is not located on a body of water. The service and cooling water is obtained from deep wells as well as from the surface water of the disused lignite opencast mine in Alversdorf near Offleben .
The power plant fed on the 380-kV level on the switchgear Helmstedt in the transmission network of TenneT TSO a.
Others
The water retention basin of the power plant was created on the site of the Esbeck earthworks , one in the 6th millennium BC. Fortifications and settlements built in BC . This spot had been known since 1974 after a farmer found prehistoric shards in his field . Before the power plant was built, excavations began in 1981 on an area of around 10,000 m² under the direction of archaeologists Hartmut Thieme and Mamoun Fansa from the Hanover Institute for Monument Preservation . The finds thus obtained include around 3,000 pieces of ceramic vessels, 8,000 flint artifacts and 3,000 rock objects.
In spring 2002, most of the GDR paper money previously stored in a former military tunnel near Halberstadt was burned in the Buschhaus power station. The reason for this undertaking was a successful break-in into the tunnel system in the mountains of counters and the theft of numerous old banknotes that were supposed to rot in the system. Most of the 200 and 500 mark notes circulating in collectors' circles today come from this break-in.
