SDHp2m stands for Solar District Heating (SDH) and actions from Policy to Market. The project addresses market uptake challenges for a wider use of district heating and cooling systems (DHC) with high shares of renewable energy sources, specifically the action focuses on the use of large-scale solar thermal plants combined with other renewable energy sources in DHC systems.

The key approach of the project is to develop, improve and implement in nine participating EU regions advanced policies and support measures for SDH. In three focus regions Thuringia (DE), Styria (AT) and Rhone-Alpes (FR) the regulating regional authorities are participating as project partners to ensure a strong implementation capacity within the project. In six follower regions from BG, DE, IT, PL, SE the regulating authorities are engaged through letters of commitment. The project activities aim at a direct mobilization of investments in SDH and hence a significant market rollout.

The direct expected outcome and impact of SDHp2m is estimated to an installed or planned new RES DHC capacity and new SDH capacity (in total 500 MWth) directly triggered by the project corresponding to a total investment of 350 m. EUR and leading to 1,420 GWh RES heat and cold production per year. A multiple effect is expected in the period after the project and in further EU regions.


The project work program in the participating regions follows a process including:

  • Strategy and action planning based on a survey, best practices and stakeholder consultation
  • An implementation phase starting at an early project stage
  • Efficient dissemination of the project results at national and international level

Addressed market uptake challenges are: Improved RES DHC policy, better access to plant financing and business models, sustained public acceptance and bridging the gap between policy and market through market support and capacity building. Denmark and Sweden reached already today a high share of RES in DHC and shall be used as a role model for this project.


A project summary report is available here. It presents the results achieved and the activities rolled-out in the participating regions.
