The RheinEnergie AG is a regional power company for electricity, gas, water and heat supply, based in Cologne . The company supplies around 2.5 million people, industry, trade and commerce with energy and drinking water .
RheinEnergie is owned by two shareholders: 80 percent of the shares are held by GEW Köln , which, as a holding company, is in turn owned by the City of Cologne to 10 percent directly and 90 percent indirectly through Stadtwerke Köln GmbH . RheinEnergie's statutes stipulate that the majority of the shares must always be in municipal ownership. The remaining 20 percent are owned by Innogy .
history
For 130 years, the "Gas, Elektrizitäts- und Wasserwerke Köln AG (GEW)" supplied Cologne on the left bank of the Rhine with energy and water. As one of the largest German municipal energy and water supply companies, the GEW was 100 percent owned by the city of Cologne. In order to be prepared for the competition and the changed framework conditions, the GEW changed from a supplier for Cologne to a supplier for the Rhenish region.
This process took place as a new establishment in several stages. In 2002 the GEW transferred its facilities, personnel and operational business to "GEW RheinEnergie AG" and thus transformed into a pure holding company under the new name GEW Cologne , which holds 80 percent of the shares in GEW RheinEnergie. The RWE Group brought shares in the surrounding energy supply companies as well as customers, water networks and has a 20 percent stake in the new company. As of April 1, 2005, the company renamed "RheinEnergie AG".
In spring 2014, RheinEnergie moved into a new main headquarters (Parkgürtel 24).
Investments and subsidiaries
In October 2007 RheinEnergie acquired a share package of 16.1% in the listed MVV Energie from the city of Mannheim . MVV Energie has a 28% stake in the large Mannheim power plant , which is the largest hard coal power plant in Germany. RheinEnergie sold the shares in MVV Energie again in April 2020.
In February 2011, RheinEnergie took over 49.6% of the coal- fired Rostock power plant from RWE Power and Vattenfall .
RheinEnergie is involved in numerous municipal utilities in the Rhineland such as B. in Gummersbach, Hürth, Bergisch Gladbach, Leverkusen, Dormagen, Leichlingen, Lohmar, Pulheim, Bornheim, Troisdorf and Bonn.
RheinEnergie has founded subsidiaries to operate its power generation systems, such as B. RheinEnergie HKW Rostock GmbH, RheinEnergie HKW Niehl 3 GmbH, GT-HKW Niehl GmbH, RheinEnergie Windkraft GmbH, RheinEnergie Solar GmbH or RheinEnergie Biokraft Randkanal-Nord GmbH & Co. KG.
Products and customers
RheinEnergie supplies electricity, natural gas, heat and drinking water to private and business customers and, together with partners and affiliated companies, supplies an area from the Rhein-Erft district west of the city of Cologne to far into the Bergisches Land in the east, from Leverkusen in the north to the north Rhineland-Palatinate. In addition, RheinEnergie supplies major customers throughout Germany with electricity and offers energy services such as contracting .
electricity
In 2018 RheinEnergie sold 17,047 GWh of electricity. It generated 5,189 GWh itself, which makes up 30.4%. RheinEnergie buys the remaining electricity through its subsidiary RheinEnergie Trading GmbH on the Leipzig electricity exchange ( European Energy Exchange ).

The share of renewable energies in the electricity generated by RheinEnergie itself is very low at 5.6%. For comparison: the national German average of renewable energies in terms of net electricity generation was 40.6% in 2018.
gas
RheinEnergie supplies customers in Cologne and Rösrath with natural gas. In the urban area of Cologne, the share of natural gas in the space heating requirement of households, small businesses and public buildings is 66.7 percent.
Drinking water
RheinEnergie supplies Cologne, Frechen, Bergisch Gladbach, Brühl and the south of Pulheim with drinking water. Eight waterworks and two separate drinking water networks (left and right bank of the Rhine) ensure the supply. The water comes from the groundwater flow that flows through the underground of the Cologne Bay. This is fed by seepage from precipitation and bank filtrate , which is naturally filtered and cleaned through huge layers of gravel and sand. In this way, there would be no bottlenecks in the drinking water supply in the region even in extremely dry times. The quality of the drinking water is ensured through daily water analyzes and regular official controls. The measuring points are distributed across the entire city area - in the run-up to the collection systems, at the wells themselves, in the waterworks, in the distribution network and at the customers' premises. The drinking water in the RheinEnergie supply area is predominantly in the "hard" range.
District heating
In RheinEnergie's combined heat and power plants, not only electricity but also heat is generated at the same time in order to make the best possible use of the energy source and to reduce CO 2 emissions. The Niehl II thermal power station alone could supply 300,000 households in Cologne with district heating . In the inner city of Cologne there is more than 50 percent coverage of the heating requirement through district heating. The district heating pipes and connections are constantly being expanded. Important major customers in the district heating sector include WDR , the University of Cologne , Ford Werke and Deutz AG .
Network operator
The Rheinische network mbH ( RNG ), a 100% subsidiary is, since 2006 in and around Cologne network operators in the Rhine region.
Technical equipment
Rheinenergie operates various heating and power plants in Cologne : as well as systems for renewable energy.
Thermal power stations
Cologne-Merkenich thermal power station
As the only RheinEnergie plant, the Merkenich thermal power station can burn lignite granulate in addition to the main fuel natural gas in its own plant. In addition to electricity with an output of 75 MW, the gas and steam turbine technology also provides district heating and process steam (thermal output: 146 MW) for trade and industry in the north of Cologne. A separate line route leads to the Ford works.

Cologne-Niehl thermal power station
For more than 30 years, the Niehl 1 thermal power station operated with natural gas was the backbone of the electricity and district heating supply for Cologne city center and the west of Cologne. In April 2005, the Niehl 2 thermal power station replaced the previous system. This gas and steam turbine system should have an efficiency of up to 86 percent.
Niehl gas and steam turbine thermal power station 3
The new Niehl 3 thermal power station has been in operation since April 2016, "the keystone of conventional energy generation at RheinEnergie". The new CCGT block in the direct vicinity of the Niehl II thermal power station has an electrical output of 450 megawatts and also provides district heating with an output of up to 265 megawatts. According to Rheinenergie, the Niehl 3 thermal power station is an important component of the energy transition, as it can flexibly control its electricity generation at short notice and thus helps to safeguard the fluctuating electricity generation from renewable energies. Environmental activists criticize the new building because the money could have increased the share of renewable energies in RheinEnergie's energy mix from 4% to 11%. In addition, it is an unsafe investment, as the gas price could rise significantly and the sales opportunities for electricity generated from fossil fuels deteriorate. According to RheinEnergie, Niehl 3 works economically because the combined cycle will primarily provide district heating for existing and new Cologne districts.
The two power plant blocks Niehl 2 and Niehl 3 have an electrical output of 413 MW and 459.9 MW and a thermal output of 256 MW.

Merheim thermal power station
The smallest cogeneration plant in Cologne supplies part of Cologne's electricity and district heating for the surrounding districts and for the Merheim Clinic and Holweide Hospital .
Südstadt heating plant
Cologne's oldest thermal power station in terms of history was put into operation as a pure power generation system and one of the first AC power stations in Germany as early as 1891. A modern gas turbine can be found within the completely restored Art Nouveau structure. The system currently works exclusively as a heating plant and provides heat for downtown Cologne.
More power plants
Other RheinEnergie power plants are the Junkersdorf combined heat and power plant, the Bocklemünd heating plant and the Deutz heating plant. In addition, RheinEnergie has a 49.6 percent stake in the Rostock hard coal-fired power station .
Renewable energy systems
solar power
Andasol 3
RheinEnergie has a 12.3 percent stake in the 50 megawatt solar thermal system "Andasol 3" in Granada, southern Spain. The solar thermal system, which went into operation in 2011, will supply around 60,000 households with electricity.
Photovoltaic system on the Cargo Service Center, Cologne / Bonn Airport
The facility, the size of a football field, went into operation in 2009 and generates electricity for 110 Cologne households with 1,685 modules.
Photovoltaic system on the roof of the composting plant in Niehl
The largest plant on the left bank of the Rhine generates 480 megawatt hours of electricity per year and thus supplies around 160 households in Cologne.
Wind energy
RheinEnergie's wind farm portfolio comprises 19 wind farms with a total capacity of more than 100 megawatts. The plants, most of which are located in northern Germany, produce 200 million kilowatt hours of electricity annually, which corresponds to the consumption of 80,000 households.
Bioenergy
Euskirchen-Schornbusch biogas plant
RheinEnergie has a 40 percent stake in the biogas plant in Euskirchen-Schornbusch, which generates around 1.5 megawatts of electricity from corn and other raw materials.
Biogas plant Randkanal-Nord
The plant in Cologne-Roggendorf started operation in November 2011. The plant is supplied with raw materials by 16 farmers in the region. It produces electricity for the equivalent of 3,000 households and heating for around 1,000 apartments in the Dormagen district of Hackenbroich. According to RheinEnergie AG, this makes the system one of the most efficient and climate-friendly in Germany.
Recycled heat from sewage gas
In cooperation with the large sewage treatment plant Stammheim of the Stadtentwässerungsbetriebe Köln (StEB) and GAG Immobilien AG, RheinEnergie has been supplying around 1,700 apartments and 100 single-family houses with climate-friendly heat since spring 2012. This is generated from sewage gas that is produced during wastewater treatment.
CO 2 emissions
With its combined heat and power plants in Merkenich, Niehl, Merheim and Südstadt alone, RheinEnergie causes around a fifth of the CO 2 emissions in the city of Cologne. Added to this are the CO 2 emissions from the Rostock hard coal power plant , in which RheinEnergie has a 49.6% stake, and the proportionate CO 2 emissions from the large Mannheim power plant until 2019 . RheinEnergie held 16.3% in MVV Energie , which in turn has a 28% stake in the large Mannheim power station .
