The Stadtwerke Dusseldorf AG is a municipal utilities. The company operates in the fields of electricity, natural gas, drinking water and district heating and is majority owned by the energy group EnBW .
history
The gas supply for the city of Düsseldorf dates back to 1843. In 1843 the company Sinzig & Cie. concluded a 20-year contract, according to which the company had to supply the so-called "patent gas" (a mixture of coke oven gas and resin gas ). Since the gas was of poor quality and overpriced, the city of Düsseldorf decided to build its own gas works with a pipe network. This first urban gas plant was built on the area between today's Luisenstrasse, Hüttenstrasse and Helmholtzstrasse and was opened on September 20, 1866 - one day before the contract with Sinzig & Cie. - put into operation. The first municipal gas with a six-kilometer-long supply network and 753 “dazzlingly bright” gas lanterns was initially only used for lighting. Two years later, gas emissions were already 1,840,000 cubic meters . Deliveries were made in 1866 to customers and 800 lanterns. Five years later, the levy had already doubled. It was reported by 4064 customers. Düsseldorf's nights became noticeably lighter: 2448 public lanterns were fed with city gas.
In 1866 a cholera epidemic had killed 111 Düsseldorf residents, and the social costs for the accommodation of the sick were a burden on the city coffers. From a hygienic point of view, a public water supply was decided, which went into operation on May 1, 1870 with a well in Flehe and a 30-kilometer supply network. Düsseldorf was one of the first cities in the Rhine Province to have a central water supply.
When gas production had reached 5.25 million cubic meters a year , a 47-acre property was purchased in Flingern , at that time three kilometers from the city gates, for 205,551 marks . On December 15, 1890, the workers loaded the first stoves in the new gas works on Höherweg. In the meantime, the pipe network had grown considerably: the modest 60,916 meters in the year it was founded had grown to an impressive 181,608 meters by 1891. One problem was the by-products that were generated during gas production. At first they were nothing more than annoying garbage. Later, tar and its valuable ingredients, including benzene and naphthalene , were first taken away from the developing organic chemistry. Markets first had to be found for ammonia , sulfur and the large quantities of coke . Some of the coke was sold to southern Germany and Alsace .
On December 1, 1891, the power supply was added by building our own power station with a DC generator in Düsseldorf-Flingern. The power plant output was 442 kilowatts . The history of the Flingern thermal power station began with this system .
After the old gas works on Luisenstrasse was shut down in 1898, the gas works in Flingern supplied the city with gas. In 1903–1904 a new administration building was built on the corner of Luisenstrasse and Scheurenstrasse on the site of the disused old gasworks. This was elaborately designed in the style of the neo-renaissance :
"The street fronts are performed in the Renaissance style, namely the plinth made of Upper Hessian basalt lava, the structure made of Palatinate sandstone (...) The rear fronts receive smooth cement plaster, drawn main cornices and drawn grooves as window frames, as well as sandstone window sills and basalt lava splinters."
In 1906 the power plant in Flingern was converted from steam engines to turbines , and since then it has been producing both direct and alternating current .
The extensive expansion of the tram network made it necessary to build a new, high-performance hard coal power station between 1912 and 1913 . Flingern II was built according to the technical concept of the power plant engineer Georg Klingenberg , the architects Peters and Langheim are believed to be the originators of the structural design with clear Art Nouveau influences . Three AEG turbines with a total electrical output of 42 megawatts (MW) ensured the rapid expansion of local urban transport. The explosive growth of Düsseldorf pushed the Stadtwerke to the second expansion stage of Flingern II in 1927 . The electrical output was now 58 MW, which were generated by five turbine sets. The necessary pressure was generated by 24 steep-tube steam boilers in two boiler houses. From 1928, a combined heat and power system ensured lower heating costs for the exhaust gas-plagued Flingerians and their neighbors. The district was first developed in Flingern. The Flingern location is still used today to generate energy. At that time, all types of supply were in municipal hands.
By 1924, water production in Flehe had grown to five separate pumping stations with 117 wells. The Lörick waterworks was built from 1923 to 1926 . When Flehe reached its production limit in 1925, the Am Staad waterworks went into operation in 1933 .
In 1930, after 45 years of power supply at home and abroad, the foundations for general security of supply were laid and mutual assistance in the event of interruptions was agreed. Rheinisch-Westfälisches Elektrizitätswerk AG ( RWE ), founded in 1908, continued to expand through the takeover of numerous smaller supply companies. Because of its cost-saving large-scale brown coal power stations, it was able to offer lower electricity prices. The transfer of the municipal power station to a newly founded stock corporation was considered, but views on the sale of the municipal operation were divided in the Düsseldorf city council .
In 1933 the name municipal utilities was abolished. The first so-called Stadtwerke Düsseldorf are the Amt 81 Stadt .
The development of high pressure boiler technology made a renewed conversion of Flingern II seem sensible in 1936 . However, it was not commissioned until 1940 with a significantly reduced number of boilers and three new turbines. The boiler house B only served the reserve. The Second World War brought despite numerous bomb hits any permanent impairment of the power plant operation. In order to be able to meet the needs of the city, the municipal utilities expanded the Flingern power station in four stages from 1949 to 1955 to a total of 242 MW.
The economic boom brought the people of Düsseldorf mid-1950s, her biggest ever power plant in the city harbor. The hard coal-fired power station Lausward went online in 1957 with its first energy-generating unit, Anton, with 10 MW. The Berta (1962, 130 MW, coal), Caesar (1965, 130 MW, coal) and Dora (1967, 150 MW, coal) units followed.
The first expansion stage of the Auf dem Grind waterworks was completed in 1954 and comprised two pumping stations, each with a daily output of 65,000 cubic meters. In 1955 the plant was in operation all year round for the first time.
In 1956, an interest group was set up to prepare for the construction of a test nuclear reactor. In 1959 this became the Arbeitsgemeinschaft Versuchsreaktor GmbH (AVR) , a consortium of 15 regional electricity suppliers under the leadership of Stadtwerke Düsseldorf as the owner and operator. The feasibility and functionality of a gas-cooled, graphite-moderated high-temperature reactor for generating electricity should be researched in Jülich .
1961 was a milestone for the drinking water supply. For the first time, all of the drinking water from the Am Staad waterworks was treated with ozone and activated carbon filters using the Düsseldorf process used worldwide .
In 1963 the Holthausen waterworks was built and went into operation in 1964.
On November 2, 1965, a waste incineration plant went into operation next to the Flingern thermal power station . It works with a combustion technology developed in-house, the roller grate firing "System Düsseldorf" . To date, more than 60 plants worldwide have been operated with such a system. In Garath , a completely desulfurized and denitrified hard coal cogeneration plant went into operation for the first time, thus limiting the entry of pollutants.
From 1967 Düsseldorf was switched from town gas to natural gas . The conversion of 119,806 households and 5,300 commercial and industrial customers took exactly from April 24, 1967 to May 15, 1970. The costs for private households were covered by the municipal utilities. After 102 years on the factory premises in Flingern, the classic process of in-house gas generation came to an end on April 29, 1968. Düsseldorf was the first city in West Germany with a 100% natural gas supply.
The operation of the municipal supply within the city administration ended on December 18, 1972. The "Amt 81" became the Stadtwerke Düsseldorf AG , with the city holding 100 percent of the shares. The public obligation, which was already regulated by the Energy Industry Act in 1935 , has not changed. The law makes it compulsory to make general conditions and general tariff prices uniform for the entire supply district. In Flingern, the aging boiler house B was demolished in favor of a modern gas turbine power plant. In 1973 six Rolls-Royce emergency generators were housed here. These are aircraft engines that can be operated with light heating oil and together deliver 90 MW of electrical power.
The commissioning of the Emil gas turbine block in the Lausward coal-fired power station made it possible to completely shut down the exhaust-gas-intensive Flingern II coal-fired power station , which was a fully functional emergency reserve until the decommissioning decision of April 8, 1998.
In 1982 the company's ownership structure changed. By bringing in its electrical systems in the south of Düsseldorf, RWE acquired a 20 percent stake in Stadtwerke Düsseldorf's share capital. The city contributed all shares it owned to the Düsseldorfer Stadtwerke - Gesellschaft für Beteiligungen , founded in 1983 , with which the company holds an 80 percent stake in the Stadtwerke. In 2007 , the holding company changed its name to Holding der Landeshauptstadt Düsseldorf GmbH . The management of the new company was relocated close to the city.
The city ports were taken over by the city of Düsseldorf in 1990. The main reason was to secure the power plant location on the Lausward. In 2003 the Neuss -Düsseldorfer Häfen were merged into a new port company .
In 1996 the power plant modernization project started , during which the Lausward units Berta , Cäsar and Dora were shut down and the coal unit Anton was "replaced" with a gas and steam plant . Block Emil was modernized.
In Garath in 1998, the aging coal block was converted to run on natural gas and light heating oil. The thermal output was now 100 MW. The chimney, visible from afar, was demolished in favor of a smaller one. The Lausward power plant has been gradually converted into a modern and, above all, clean gas and steam combined cycle power plant that will deliver 520 MW of electrical output and 330 MW of district heating .
One year later, the Flingern waste incineration plant was completely owned by Stadtwerke Düsseldorf. The neighboring gas turbine power plant was converted to steam operation. A pipeline several hundred meters long now conducts steam at 500 ° C from the waste incineration plant to the neighboring thermal power station, which now supplies 55 MW of electrical power and 100 MW of district heating. In 2000, certification as a waste management company was finally carried out by TÜV Rheinland .
On July 4, 2001, the city council decided to sell 29.9 percent of the shares to the Karlsruhe energy supplier EnBW . The planned sale of significantly more shares was prevented by a referendum .
The Stadtwerke Düsseldorf were centralized, and the administration also moved to Flingern, the place where the first power plant was built. At the international real estate exhibition in Cannes ( MIPIM ), the new administration building took second place. During the construction the focus was on the illustration of tradition and modernity; Listed building areas of Flingern II were connected with glass-modern office wings. The turbine hall was designed by Jorge Pardo .
In 2004, RWE had to part with its block of shares for anti-trust reasons. The GEW Köln AG bought the 20 percent.
In 2005 the Stadtwerke's first wind power plant was built in Willich .
On December 16, 2005, the city council decided to sell another 25.05% of its own shares for 361 million euros to EnBW, which thus holds the majority of 54.95 percent in Stadtwerke Düsseldorf. The city still has a blocking minority of just over 25% .
The petition for citizens that was started thereupon, which received more than 95,000 signatures within a few days, was declared inadmissible by the council on January 9, 2006, as the decision could no longer be withdrawn.
Also in 2006, Remondis acquired 49% of AWISTA and 51% of its sister company ATG & Rosendahl.
In November 2007, the Garath biomass cogeneration plant went online as the most important contribution to the field of renewable energies . The fuel consumption is 40,000 tons of wood chips annually, which have to be brought in by up to ten trucks every day. The aim is to reduce the burden on the neighboring Garath natural gas thermal power station in a cost-effective manner, since woodchips are more stable in price than natural gas, which is now difficult to calculate, due to the lack of connection to the oil price. The turbine output of the biomass cogeneration plant is estimated at 3.5 MW electrical output. The thermal output, however, is 10 MW. A regularly controlled flue gas cleaning system protects against health impairments from fine dust .
In 2008, Stadtwerke Düsseldorf took over a 49.9% stake in Monheim Elektrizitäts- und Gasversorgung GmbH (MEGA) in Monheim am Rhein from rhenag , a subsidiary of RheinEnergie and RWE , as well as 49.9% in Hildener Stadtwerke . In 2014, the shares in MEGA were bought back by the city of Monheim am Rhein, so that MEGA is again 100% a subsidiary of the city of Monheim am Rhein.
According to the company, in 2008 only 40 percent of the electricity sold by the municipal utilities in Düsseldorf was generated locally. The rest must be bought. In 2011, the supervisory board approved the construction of a highly efficient gas and steam turbine power plant on the power plant site on Lausward. It went into operation on January 28, 2016. In May 2012, Siemens was awarded the contract as general contractor for the construction of the plant. In 2013, the municipal utilities and the Norwegian energy group Statoil signed a 15-year supply contract for natural gas. The district heating storage facility was put into operation in 2017.

Renewable energy
In 1990, the Stadtwerke built their first small wind power plant on the banks of the Rhine near the Süd sewage treatment plant in Düsseldorf-Hamm . The operation has meanwhile been discontinued due to the low yield. In 2004, two Vestas V-80s with a total nominal output of 4 MW were connected to the grid at a location in Willich . Onshore performance is continuously being expanded. Offshore there is a participation in the offshore wind farm EnBW Baltic 1 . Stadtwerke Düsseldorf AG owns or is involved in the following systems:
| Location | Type | power | Hub height and rotor diameter |

In addition, four 500 kW biogas plants with an integrated combined heat and power unit , also a total of 4 MW nominal output, have been operated in Schöppingen , Delbrück and Brüggen .
For a long time, photovoltaics played a subordinate role for Stadtwerke Düsseldorf. Since 2006 the municipal utilities have increased the capacity to around 4.9 MWp . You have the following systems:
| Location | power | Module area | Installation |
|---|---|---|---|
| Dusseldorf Airport | 2000 kWp | approx. 13931 m² | 2011 |

The Wildshausen wood gasification plant near Arnsberg with a combined heat and power unit and combined heat, power and cooling system was created in cooperation between the municipal utilities and the Biomass company . The wood gas is obtained from wood chips . The prototype with a nominal output of 270 kW is to be developed into an export product. There are also larger wood chip systems for hot water in Düsseldorf and Viersen , for example at the Stockumer Höfe with 850 kW or at Quack + Fischer with 300 kW.
Stadtwerke does not consider Düsseldorf a worthwhile location for geothermal energy . Nevertheless, a 111 kW system is operated on the premises of the Walter Flender company. The liberalization of the electricity market is attracting numerous competitors to the city in this area. In Tönisvorst , 16 houses are still heating with a 110 kW system from the Düsseldorfer Stadtwerke.
In May 2010, the 100% participation in Düsseldorfer Consult was renamed Grünwerke to expand the renewable generation portfolio of Stadtwerke Düsseldorf . The company's purpose is the acquisition, planning, construction and operation of regenerative generation plants with a focus on wind and sun.
Electromobility
Stadtwerke Düsseldorf provides an extensive charging infrastructure. With over 80 charging stations and 190 charging points in the municipal utility area, it is possible to charge electric vehicles. The pillars each have two type 2 plugs and two Schuko plugs .
To finance the expansion of the charging infrastructure, which is to be pushed further, charging has been subject to a charge since July 2018. In the course of this, the Stadtwerke Düsseldorf joined the charging network.
Stadtwerke is taking part in e-CROSS GERMANY with a stand and opportunities for test drives with electric cars, scooters and pedelecs .

Stadtwerkepark
The 2.1 hectare Stadtwerkepark, opened by Mayor Joachim Erwin and Ministerialrat Karl Jasper after a 13-month construction period , is tailored to the needs of children and young people. Shielded by a 5 meter high noise barrier made of bluish glass, the winning competition design by the landscape architects Matthias Förder and Annette Demmer offers facilities and spaces for skateboarders and inline skaters, beach volleyball and table tennis players, chess and boules players . Other play facilities for younger children, such as a sand playground with a water and mud system, a sheet metal play ship with a slide and swings, are spread across the area.
The former gatekeeper's house of the Stadtwerke was completely rebuilt and now serves as an all-weather meeting place for children and youth recreational facilities from the area. The design of the plastic sculpture welcoming committee (original title Nice, that you are there! ) Comes from pupils of the community elementary school Flurstraße and was developed in collaboration with the renowned artist Klaus Sievers . The structural implementation was carried out in the Hattingen workshop by Stephan Marienfeld , who has already carried out many designs from the international art scene. The mosaic pictures in front of the gatehouse were laid by children of the Kleine Freiheit day care center under the direction of the artists Viola Werner and Armin Kaster.
The municipal utility park, which cost 1.47 million euros, was financed from funds from the State Program Social City NRW , as well as from the city of Düsseldorf's own funds. Stadtwerke Düsseldorf donated only the front part of their premises on the corner of Höherweg and Kettwiger Strasse in Düsseldorf-Flingern and decided not to cut down the sparse tree population there.
Since the opening, walnut trees , a Russian linden tree and rhododendrons have joined an older ensemble of ash trees , maples , a copper beech , chestnut trees , a birch and an American linden tree . Some of the existing tree species are so exotic that they cannot be easily identified. Also worth mentioning is the tiny bamboo labyrinth studded with boulders, which offers protection from wind, sun and prying eyes. The extensive lawns are designed as playgrounds and sunbathing areas and also serve as an event location for open-air concerts, for which the noise level from the skateboarding facility and the traffic noise on Kettwiger Straße have proven to be deficiencies. The ample seating on the aesthetically pleasing concrete walls at the edge of the arched paths is usually not shaded. The rear part of the park is under video surveillance near the new Stadtwerke headquarters and the old, listed cooling towers of the former Flingern II coal-fired power station .
