The Kassel power plant (KWK) is a combined heat and power plant on Dennhäuser Strasse in the Niederzwehren district in the south of Kassel . Today it comprises two organizationally and structurally separate power plant blocks : The Kassel district heating power plant (FKK) and the combined heat and power plant (Kombi-HKW) . In the immediate vicinity is located on the banks of the Fulda the hydroelectric plant Neuemühle .
History and technology
Community power plant (1955–1987)
There was already a power plant at the site from 1955 to 1988, which was operated jointly by PreußenElektra and the municipal works . It was put into operation in 1957 under the name "Gemeinschaftskraftwerk Kassel" with an output of 144 MW. The fuel was mainly lignite from the North Hessian mining area .
From 1986, two new systems were built separately by the two operating companies using the main building and the exhaust gas system, and they went into operation in 1988. These are the district heating power plant (FKK) and the combined heat and power plant.
District heating power plant (from 1989)
The district heating power plant built by PreußenElektra was operated from 1987 to 2010 by E.ON and "Kasseler Fernwärme GmbH". At that time it had an electrical output of 38 MW and a thermal output of 150 MW. a. the delivery of the VW plant in Baunatal . The grid connection is made on the 110 kV level in the Avacon grid .
Thanks to the cogeneration of heat and power , the power plant generates 144 million kWh of electricity annually, which corresponds to the energy requirements of around 36,000 average households. In addition, 320 million kWh of heat are fed into the district heating network. This can heat around 10,000 households.
Primary fuel was initially lignite from the North Hessian mining area ( Hirschberg colliery ), after the end of mining there, lignite was obtained from other mining areas and hard coal was fired. The enclosed inclined conveyor belt can be seen in the photo. The pre-dried raw coal is transported up to the grinder on this. From here the finely ground coal dust is blown into the furnace. The cooling water for the condensers is taken from the nearby Fulda and fed back into the river after the cooling process. This means that no complex cooling towers are necessary.
In 2010 Kasseler Fernwärme GmbH took over the shares in E.ON Kraftwerk GmbH. With the transfer of Kasseler Fernwärme GmbH to Städtische Werke Energie + Wärme GmbH in 2013, processes for power plant optimization began. In addition to converting the power plant's air conditioning to absorption refrigeration technology in 2014, test phases for converting to substitute fuels of biogenic origin ( sewage sludge ) were successfully completed in 2015 . The associated approval procedures have meanwhile been approved by the Kassel regional council. The substitute fuel has been used since the beginning of 2016.
The district heating power plant has been used with slightly reduced capacity since January 2017 - due to the CHP subsidy for the combined heat and power plant. Overall, the proportion of biogenic fuel sewage sludge has been increasing steadily since 2016 and contributes to decarbonization. The plant also incinerated around 55,000 tons of sewage sludge in 2017. In 2017, a concept was drawn up for the construction of a sewage sludge dryer to increase the intake quantities and thus further decarbonise the district heating power plant. The sewage sludge is to be dried with district heating from our own production.

Combined heating and power plant (from 1989)
The combined heat and power plant consists of two natural gas-fired combined cycle plants and a steam turbine system for the combined generation of electricity and district heating. There are also hot water boilers and auxiliary steam generators on the system. The power plant is controlled via the local control center. The second gas turbine went into operation in 2005.
The grid connection takes place at the 60 kV high voltage level in the power grid of the distribution network operator Städtische Werke Netz + Service GmbH .
