Annex TS5: Integration of Renewable Energy Sources into existing District Heating and Cooling Systems

with focus on large-scale solar thermal, large heat pumps, renewable P2H-systems, geothermal, biomass and large heat stores in combination with CHP and surplus heat



IEA DHC has approved the preparation of a new international cooperation project focussing on the Integration of Renewable Energy Sources into existing District Heating and Cooling Systems (RES DHC). The overall aim of this cooperation is to address R&D challenges related to this topic, in order to get in place renewable heat sources as environmentally friendly and emission free heat generation technologies for the DHC sector.
The specific objectives of the task-shared annex are:

  • Gain knowledge about and develop enhanced solutions for the technical and operational integration of RES plants into existing traditional and modern DHC systems
  • Provide practical know-how on RES DHC project development, technical solutions and business cases to the DHC market actors
  • Develop and show-case innovative demo cases driven by DHC market actors and in cooperation with RES market actors (for both, technical and organizational solutions)
  • Develop advanced instruments addressing non-technical market barriers and opportunities


Please contact the coordinators of the Annex TS5 preparation if you want to join the Task-shared Annex or have any other questions concerning Annex TS5. Thank you.
