history

Gas supply

The energy supply of the city of Hanau begins in the age of industrialization and the connection of Hanau to the railroad in 1848. In the same year, the entrepreneur Herrmann Pabst received the approval to build a gas preparation plant outside the city in front of the Nürnberger Tor . The headquarters of Stadtwerke Hanau is still located on the property on Leipziger Strasse.

Pabst had the gas produced delivered to customers by horse and cart. Due to a lack of economic success, he had to sell the work to Heinrich Friedrich Ziegler two years later. He had cast iron pipes laid in the streets of the city center to set up gas lighting. House connections were also added later, with the customer base mainly consisting of business and public spaces, especially restaurants.

In 1870 the city of Hanau acquired the Ziegler gas factory and subsequently operated it as a municipal gas works . The plant was rebuilt several times, for example in 1909/1910 when, after only nine months of construction, a modern chamber furnace plant with a large coal silo went into operation. The architect was Hans Seyffert , Berlin. The gas works was connected to the Hanauer industrial railway in 1919/20 . On December 12, 1944, it was destroyed in a major attack by the US Air Force on the main train station and the surrounding industrial areas. With that the own gas production came to an end.

Drinking water

In modern times, the city of Hanau was mainly supplied with water via private and public wells that were fed by the Kinzig , which surrounds the city center on three sides. The pharmacist Wilhelm Carl Heraeus noted in a treatise in 1873 that the water was of very poor quality. A water pipeline made of beech beech trees , which had existed since 1750, had been blocked after a flood since 1845; attempts to restore it were abandoned in 1853. It was not until 1889 that the city acquired two properties in the Dörnigheim district and had three wells, a waterworks and a tower built. At the same time, construction of the pipeline network began in Neustadt. The waterworks started operating in 1890. Necessarily, in 1891, work on the canalization of the city began.

Former waterworks III in Wilhelmsbad, company building

The capacity of waterworks I was already exhausted in 1897. In the following year, the planning of a second waterworks began at Leipziger Straße 79. It was given a two-storey villa-style building, designed by city planner Thyriot. With the connection of Kesselstadt in 1907 and the simultaneous relocation of two railway regiments to Hanau, water consumption had risen again so strongly that another waterworks, Wasserwerk III , had to be built on Burgallee (1911/12). In 1922 the Wolfgang II waterworks (near Großkrotzenburg ) was taken over from the former Wolfgang powder factory and continued as Wasserwerk IV .

Power generation

After the city fathers took the decision in 1887 to build a municipal power station, it was able to supply the first electricity in November 1898. The location of the electricity works was on Leipziger Strasse behind the gas works. One of the first customers was the “Zum Riesen” hotel on Heumarkt. But also city buildings such as the city ​​palace , city ​​theater , Neustadt town hall , schools and the hospital were soon connected to the supply. Another big customer was the Hanau tram , which started operating in 1908.

The company's own electricity generation came to an end for the time being with the canalization of the Main and the construction of the barrages. From 1921 onwards, Hanau obtained electricity from the turbines in the Kesselstadt barrage . The power station was converted into a transformer station and was finally destroyed in the air raid on Hanau on March 19, 1945 .

District heating

In the 1960s, the desire for optimal energy use through combined heat and power generation led to the energy supply of a new district, Hanau Weststadt , being geared towards district heating . The supply began in the spring of 1966, initially with mobile heating systems, and from September 1969 a stationary system. Due to the further development, a separate block-type thermal power station was built, which went into operation in 1982, further systems followed.

Cost-intensive renovation measures later meant that district heating was also obtained from the Staudinger power plant near Großkrotzenburg, which already supplied parts of Hanau and Großkrotzenburg. In August 2003 a 3.2 km long transport line was laid from the city center to the west city.

Merging of the corporate divisions

In 1978 the municipal utilities were merged and transformed into today's Stadtwerke Hanau GmbH. In the same year, the merger with Stadtwerke Großauheim GmbH took place . The power station in the Großauheim district was then converted into a museum with a focus on industrial history .

Since 2003 there has been a partnership with Mainova AG, which holds 49.9% of Stadtwerke Hanau.

Today's operating areas

  • Today drinking water is pumped by the municipal utilities in six waterworks, which covers the city's consumption by around 75%. The drinking water required in addition comes from the Spessart , the Vogelsberg or the Offenbach district . The water supply network in Hanau currently has a length of 358 km.
  • 96% of the electricity is drawn from the network. The municipal utilities operate various block-type thermal power stations in and around Hanau. Numerous photovoltaic systems have recently been added. At the end of 2018, the Hanau utility grid was 946 km in length.
  • Stadtwerke Hanau today draws natural gas from the network. The on-site pipeline network has a total length of 329 km.
  • Stadtwerke Hanau draws district heating from its own combined heat and power plants and the Staudinger power plant. It operates a district heating network with a length of 71.1 km that supplies the city of Hanau.
