The Arzberg power plant was a lignite and natural gas -fired power plant near Arzberg in Upper Franconia ( Bavaria ). The power plant, initially built in 1915 as a purely coal-fired power plant, was shut down at the end of 2003 and then demolished. It was last operated by E.ON. As a result of the energy transition and the nuclear phase-out, there are considerations to build a new combined cycle power plant at the site.
history
Construction and operation
In order to meet the increasing demand for electricity in Upper Franconia due to increasing electrification , the Kingdom of Bavaria signed a contract with the Berliner Elektricitäts-Lieferungs-Gesellschaft (ELG) in 1913 , in which the ELG undertook to build a power plant in the region. For the project, ELG founded the Bayerische Elektricitäts-Lieferungs-Gesellschaft AG (BELG) with headquarters in Bayreuth as a subsidiary in 1914 .
The BELG chose the city of Arzberg as the power plant location, primarily because of the cheap fuel delivery; Lignite could be delivered via rail connection from the nearby Bohemian coalfield Falkenau . The cheap cooling water supply from the Röslau , which was later taken over by the specially built Feisnitz reservoir , also played a role.
In mid-1915, after a year and a half of construction, the power plant was completed and started operation with an electrical output of 12 megawatts (two sets of 6 MW each). In 1924, BELG signed an electricity supply contract with Bayernwerk , and the power plant was connected to the 100 kV network .
During the Second World War, 1940/41, the output was increased by 15 MW to 27 MW by adding another boiler and steam turbine set. After the end of the war (1954, 1957 and 1960), further renovation and expansion measures followed, increasing the output to 89 MW. The three previously operated power plant blocks with 107, 220 and 130 MW went online in 1966, 1974 and 1980. In return, all older units were shut down in 1980. Unlike all the others, the 220 MW block was not fired with lignite but with natural gas . As a result of the significantly stricter exhaust gas limit values, the power plant was equipped with a modern flue gas cleaning system in 1990 .
In 1983 BELG merged with Überlandwerk Oberfranken (ÜWO) to form Energieversorgung Oberfranken AG (EVO) . This in turn merged in 2001 with four other Bavarian regional supply companies to form E.ON Bayern AG .
Shutdown
In the course of the above-mentioned merger, the decision was made to shut down the Arzberg power plant. The power plant was taken off the grid at the end of 2003 and then blown up in three steps. In the first step, the two cooling towers of the power plant and boiler house one fell on September 1, 2006. On December 12, 2006, boiler house two and the 193 meter high chimney followed. In step three, outbuildings such as the water tower and the administration building were blown up. After the power plant was demolished, the entire site was renatured .
Prototype for cold district heating
In the Arzberg power plant, a special form of district heating supply was used for the first time , the so-called "cold district heating". In this case, no hot steam is diverted in the turbine, which causes a slight loss of efficiency in the generation of electricity, but instead the uncooled cooling water is taken after the turbine condenser. As a result, such a system can be retrofitted in any existing power plant without major structural effort. Since the temperatures in the district heating network are lower than in conventional heating networks, the flow temperature is instead raised to the required level by means of a heat pump . The heat pumps work very efficiently because the temperature difference to be bridged between the cooling water temperature (25–35 ° C) and the flow temperature is low. In Arzberg, the school, the swimming pool, as well as businesses and residential buildings were heated in this way.
