Out Target Group

Target group are municipalities of different sizes and energy supply systems. It will be distinguished between municipalities with or without district heating system.

Municipalities play an important role in the German energy revolution, as they can manage the energy supply structure. One way is the increased use of trigeneration e.g. with centralized or decentralized district heating systems owned by the municipalities. Cooling with trigeneration can be used especially by industries or companies with high refrigeration need:

  • institutions in the health sector (Hospitals, medical centers)
  • institutions in the education sector (Research- or administrative buildings)
  • the municipal housing sector

An efficient provision of cooling, heat and power via Trigeneration, can lead to a decrease in energy expenditures in municipalities and therefore increase profitability.

In order to receive reasonable results, municipalities of different sizes as well as with centralized and decentralized district heating systems will be analyzed during the project. 

More information

Germany has currently approximately 80 large cities with more than 100 000 inhabitants, which implemented mainly centralized district heating systems.

Cities between 20 000 and 100 000 inhabitants, in which approximately 590 municipalities exist, show a lower usage of centralized district heating systems. 

Municipalities are a core partner in the research project, as they participate in many usage areas of energy, heat and cooling as provider (municipal energy provider) as well as user (institutions in the municipalities), with high potential for CHP or CCHP. 

Municipal users of trigeneration are e.g.:

  • Local hospitals
  • Local swimming 
  • Local data centers
  • Administrative buildings
  • Local wastewater treatment plants

Users with a low need of cooling and which are therefore mainly in the focus for CHP usage: 

  • School buildings
  • Housing development areas

Municipalities are often stakeholders of many companies and can therefore influence the energy supply directly or indirectly. Important participants are:

  • Local utilities companies
  • Local housing associations
  • Infrastructure: hospitals, libraries, exhibition centers, freight centers, airports, etc.

Apart from the explicit examples of cooling need in municipalities mentioned above, users of centralized or decentralized district heating play as well an important role. Existing users of district heating as private households, industry, handcrafts or public facilities can be asked for potential usage of heat for cooling.

During the project, the following cities will be analyzed:

  • Nuremberg
  • Nuremberg is a large city in Bavaria with approx. 500.000 inhabitants and a centralized district heating system.
  • www.nuernberg.de
  • Potsdam
  • Potsdam is the capital of the state Brandenburg and has as well a centralized district heating supply for their 160.000 inhabitants.
  • www.potsdam.de
  • Fürth
  • Another city which is part of the in-depth analysis is Fürth, a Bavarian city of 120.000 inhabitants. It has no centralized district heating supply but some smaller district heating systems.
  • www.fuerth.de
  • Jena
  • Jena, which has as well a centralized district heating supply, is a large city in Thuringia with 110.00 inhabitants.
  • www.jena.de
  • Iserlohn
  • Iserlohn is a city in North Rhine-Westfalia with 95.000 inhabitants. They provide a centralized district heating system.
  • www.iserlohn.de
  • Flensburg
  • The city Flensburg in Schleswig-Holstein has 85.000 inhabitants and has a centralized district heating system.
  • www.flensburg.de
  • Neumarkt i.d.OPf.
  • Neumarkt in der Oberpfalz is located in Bavaria and has approx. 40.000 inhabitants. The city does not have a central district heating system.
  • www.neumarkt.de
  • Meiningen
  • Meiningen, another city in Thuringia has 21.000 inhabitants and no central district heating system.
