Model cities promote green CHP - Pacemakers for renewable energies (CHP GOES GREEN)

Download PDFDownload PDF
The goal of the project was to increase the use of RES in cogeneration, which applies to district heating and cooling as well as to decentralised cogeneration units in buildings. In eight model cities and regions (Berlin, Frankfurt/Main, Hanover, Ile-de-France, Prague, Riga, Styria, and Rhône-Alpes) promotional activities were carried out, based on a comparative analysis of the regulatory framework, market conditions and the policies of key stakeholders. The regional promotion campaigns promoted good practice examples, bundled relevant information on a website and motivated for further implementation of RES-fuelled CHP by addressing suppliers and decision makers through conferences, workshops and site visits. Multipliers on a technical level (like architects, planners and installers) were addressed through specific training seminars focusing on technical, ecological and economic aspects. Implementation was further supported by feasibility checks initiating additional good practices. In a further step, the know-how acquired by the project partners was transferred to other European cities and regions by means of international workshops and one-to-one coachings.  


  • Analysis of the European and regional legal and economic framework and its impact on the 8 regional markets. In the course of the project, the partners identified and communicated several barriers and success factors influencing the expansion of RES in cogeneration.
  • Target group specific promotion of good practices of RES-fuelled CHP addressing political decision makers, building owners, planners and installers, and pupils
  • Training of technical decision makers with regard to technical, ecological and economic aspects
  • 47 plants were taken into operation since the start of the project with a total capacity of 35 MW renewable electricity - and 142 MW of renewable heat production. This is an equivalent of 83,000 households demand for electricity and 99,000 households demand for heat - and a CO2-saving up to 416 kt
  • Transfer of generated know-how on policies and promotion activities to 13 further European cities and regions through one-to-one coachings.

Lessons learned

  • While energy providers all over Europe are looking for alternatives, with biomass as a renewable energy source becoming more and more important, chances for green CHP are still restricted due to economic reasons. Currently, the prize for biogas is still relatively high (e.g. in Germany around twice a high as for natural gas). Furthermore, political will and economic framework conditions such as subsidies sometimes leave a lot to be desired. Nonetheless, good practice examples exist in all model
  • Green CHP is a very complex and difficult matter and not easy to explain to a broader audience. However, the feedback of the first conferences and workshops shows that stakeholders and target groups are interested in the topic and that there is a demand and a need for profound information.
  • Success factors: political support and/or binding targets availability of bio-fuels and CHP technologies existence of a supply chain, availability of investment capital transparent and cost-effective grid connection target group specific promotion building certification or building codes Barriers: economic barriers (no or little subsidies, no financing option) non-economic barriers (grid connection prohibitive) project-related barriers (project development complex,no good practice ex)
