Danish District Heating Association

Danish District Heating Association (DDHA) represents over 400 members all over Denmark, supplying 64 pct. of Danish households with district heating. 

Danish District Heating Association (Dansk Fjernvarme) was founded in 1957 with the aim of organizing Danish district heating companies; facilitate cooperation between these members and to promote their interests towards authorities and other organizations, both nationally and globally. Today, the association has 50 employees located in Kolding and Copenhagen. 

Of the around 400 members
of DDHA, the largest district heating companies are owned by Danish municipalities. These deliver around two thirds of all district heating. The other district heating companies are predominantly consumer owned cooperatives. Around 1.7 million households (64 pct.) are supplied with district heating by DDHA’s members, covering around half the demand for space heating in all buildings.

District heating is regulated by a principle of non-profit and Danish District Heating Association is financed by member’s fees, which are calculated on the basis of member’s heat sales. In addition, DDHA handles publishing and projects and hosts several events including regional and national meetings, conferences, project days etc. This is both an important part of DDHA’s services to their members as well as an additional income source. In 2018, total turnover for DDHA was over €9 million. Especially DDHA’s seminars and training courses are important aiding tools in providing knowledge on various topics, ranging from production to management to legal counselling and economy.


District Heating and green energy

The share of fossil fuels used for district heating is decreasing by the year. Around 61 pct. of delivered district heating is green, sustainable heat produced from renewable energy sources. DDHA promotes the interests of its members with an aim of environmental protection and green solutions. Because district heating is a flexible system using several different energy sources it is capable of adjusting to sustainable and renewable energy sources. This is why district heating is an important part of the Danish target of being 100 pct. carbon neutral in 2050.

Renewable energy sources include: Solar energy, geothermal, biomass, biodegradable waste, biogas, bio-oil, heat pumps, and electricity produced from renewable energy sources.


Sustainable biomass:
Biomass is a necessary supplement to wind and solar power in Denmark, since Denmark cannot rely solely on these and for now biomass is the only alternative to coal in larger cities. An inter-industry agreement on sustainable biomass in Danish CHP plants has ensured that this biomass will be sustainable. From 2016 onwards Danish CHP plants are submitted to strict sustainability requirements. This is contributing to a boost in sustainable forestry creating the incentive to increase forest areas. 61% of district heating is based on renewable energy sources and with sustainable biomass it will be possible to increase this share significantly.


Our mission

Danish District Heating Association promotes the interests of the members in a visible and efficient manner, aiming for environmental protection, energy efficiency and security of supply, and with due consideration to the economy and the district heating consumers.

This is done by: 

  • Influencing rules and conditions of production, transmission, distribution and sales of district heating in Denmark
  • Ensuring development of the district heating sector
  • Gathering knowledge about district heating
  • Disseminating knowledge through meetings, training courses etc.
  • Information activities
  • Inspiring members to develop strategies and act strategically
  • Uniting district heating stakeholders in Danish District Heating Association
  • Solving common problems among members
  • Providing service to members


Our vision
Danish District Heating Association (DDHA) is an active and visible stakeholder in the Danish energy sector.

District heating is part of Danish welfare history and a symbol of how infrastructure and collective action can create a value added in society. DDHA would like to see district heating as an even more prevalent component when looking at the Danish energy sector.

We need more sustainable cities, both in Denmark and globally, but this is not done without sustainable heating and cooling and we need district energy to accomplish this. This is why DDHA is also a stakeholder in the European political energy arena. Working with our European umbrella organization, EuroHeat & Power (EHP), we are making our marks on the European Union energy agenda and trying to influence the institutions towards a more district heating and cooling-friendly system. We have already succeeded in affecting the decision-making on several matters. See more on the EHP website.

Green energy

Green Energy was set up in 2012 as a think tank to create knowledge about sustainable energy systems.

Green Energy creates knowledge about sustainable energy systems. We implement analyses and launch innovation projects that are able to clarify and document the important role that is played by district heating systems in a sustainable and integrated energy system. Our work aims to make the Danish district heating industry more visible in the Danish political debate and contribute to increased exports of green district heating solutions to foreign markets.

Specifically, we work with:

  • Agenda-setting analyses and initiatives related to energy policy
  • The documentation of innovative technology projects
  • The development of innovative business models for foreign markets
  • Launch of demonstration towns and projects that have the potential to promote district heating exports
  • Building a knowledge bank about district heating
  • The dissemination of knowledge about district heating and its advantages
