The Dettingen power plant was an oil and coal power plant operated by RWE in Großwelzheim , a district of Karlstein am Main . The power plant was just west of Gustav lake , a Tagebaurestsee the bill Gustav to which the power plant originally belonged. The eponymous Karlstein district of Dettingen is located around three kilometers to the south-east.

history

The beginnings

The lignite deposits in the basin between Spessart and Main were already known in the 19th century. The first mines opened at this time. In 1882 the director of the Amalie lignite union , Gustav Müller, discovered the deposits in Bavarian territory to the right of the Main . In 1902 he founded the Gustav colliery named after him , which was operated as an opencast mine , and two years later, in 1904, briquette production began on the colliery site. In combination with this, a coal mine power plant was operated for self-supply, which converted the coal extracted from the mine into electricity and had a striking 50-meter-high chimney.

In parallel to the increase in internal requirements, electrical energy from the power plant was also sold by contract to the surrounding communities of Dettingen, Großwelzheim and Kahl as well as the city of Aschaffenburg and some industrial companies in the region. The power generation of the power plant rose to 20 million kWh by 1914 .

Electricity generation for the region

Due to the general lack of coal during the First World War , the overland plants of the Darmstadt and Offenbach districts were merged with the mine to form the Gustav trade union . At the same time, more and more opencast mines in the area (including Emma-Süd , Emma-Nord , Freigericht) were opened up. That is why the power plant was greatly expanded and now had 19 steam boilers with 7000 square meters of heating surface and three chimneys of 90, 92 and 100 meters high. Up to 2,600 tons of coal were burned every day.

In June 1917, at the instigation of the Berlin Electricity Office, which was responsible for coordinating electricity generation in the German Reich, the union concluded an electricity supply contract with HEAG in Darmstadt . The background was that the lignite deposits in the mine and thus also the power plant should be used more economically. HEAG then built from the power plant from a 20 kV - transmission line to Darmstadt, which as of June 1918, the power plant Dettingen together with the power plant Rheinau in Mannheim ensured the power supply for the city.

After HEAG had switched the power grid of the city of Darmstadt from direct current to alternating current in 1924 (this measure was not ended until 1932), it built a new 50 kV substation on Dornheimer Weg in order to be able to transmit larger amounts of electricity. An overhead line from the Dettingen power station to the Kelsterbach substation of the RWE with a branch to the HEAG substation in Darmstadt near Erzhausen was built from 1925 to 1927. This was initially operated at 50 kV, but was already designed for a higher voltage level of 100 kV. Darmstadt's energy supply via this line began in October 1926. A connection to the Bayernwerk was also made possible via a further 110 kV overhead line to the Aschaffenburg substation . The switchgear of the power plant also served as a connection between the two power grid operators.

In the course of the global economic crisis , lignite mining became uneconomical and the first pits were closed. 1928 took over RWE the Kuxenmehrheit in the union and at the power plant. This enabled the company to expand to southern Hesse and northern Bavaria. After the end of lignite mining and the closure of the last mines in 1932, the power plant was initially shut down.

In 1938, RWE took over the power plant and from 1941 it was converted and operated as a hard coal power plant.

In 1965, a second power station block (Block A) was added, transforming it into a combined oil / hard coal power station with an output of 100  MW . In 1974 a gas turbine was added.

The furnace of Block A was converted to heating oil in 1993 and only kept operational as a reserve load power plant. In 1996 the plant was equipped with a flue gas desulphurization system.

In addition to the Dettingen power plant, construction began in 1958 on the Kahl nuclear power plant , the first nuclear power plant in Germany, which began operations in 1961 as a test reactor and was shut down in 1985. Also next to the power plant was the Großwelzheim superheated steam reactor , which was in operation from 1969 to 1971.

Shutdown and demolition

Until 2001, the power plant was only used sporadically before it was finally shut down. The 110 kV line to Kelsterbach or Darmstadt was then dismantled in some sections: In 2002 after the shutdown of the power plant in the section from Seligenstadt to Urberach, at the turn of the year 2009/2010 the branch from Erzhausen to Darmstadt. In early 2011, the section from the Dettingen power plant over the Main to Seligenstadt disappeared. This was replaced by an underground cable. The distinctive pylons can still be found between Urberach and Kelsterbach today.

The power station was demolished in 2011: the 150-meter-high chimney was demolished on February 27, 2011, the elevator tower on March 4, 2011 and the boiler house on March 22, 2011.
