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 RES, specifically the action focuses on the use of large-scale solar thermal plants combined with other RES in DHC systems.

The key aim of the project is to develop, improve and implement in 9 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 participate 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 mobilisation of investments in SDH and hence a significant market rollout.

SDHp2m follows up on the two successful projects SDHtake-off and SDHplus.

04/2018 SDH-conference in April 2018

The fifth edition of the International Solar District Heating Conference took place on April 11th and 12th 2018 in Graz, Austria. It focused on sharing market development and policy making experience, recent projects as well as latest trends in technology and system concepts.

Please refer to the conference-webpage for presentations from the conference: 5th International Solar District Heating Conference


Please find the recording and the presentations of the webinar on Solar District Heating, held in the framework of the SmartReFlex project (

The recording of the webinar Think big – Design rules and monitoring results of solar district heating systems is now available. Experts from Austria, Denmark and Germany reported on the hot topics in SDH Development. They emphasised the fact that solar district heating has an enormous potential and monitoring data shows the high reliability of the systems as well as the high performing new generation of collectors.
