This document provides case examples of district heating activities carried out within the EU. The aim is to present the diversity of contexts and conditions that can influence district heating development projects. The cases have been chosen based on different starting points and contexts.
Amiens (France) and Vitoria-Gasteiz (Spain) are examples of cities that are developing new district heating systems within a large individual heating supply system. London (UK) and Rotterdam (The Netherlands) both have small district heating systems and seek to expand these. They also have large developed gas supply systems. Denmark and Lithuania provide examples of how countries with high amounts of district heating have adopted official policies and frameworks promoting and regulating these technologies.
Cases of new deployment struggle with consumer support and perception, unknown and risky market terms and a lack of regulative support. These socio-technical systems are not adapted to district heating technology. On the other hand, there are cases of countries that have long experience with district heating. Here it is a well-known technology, regulated by the public with more stable market terms. This can still produce barriers for the further development of the system itself, as new technologies might not fit into established regimes.
This report serves as a means of displaying the differences among cases, as one size fits all solutions are not likely to meet these differences. Instead, heat planners on national and local scales must adopt solutions to the specific conditions of useful technologies, user preferences, legislation and market designs.
