Against the background of the transformation of the energy system through sector coupling, heat and other energy supply are to be explicitly considered in an integrated manner. With a view to a required municipal energy and heat concept, it will be examined in particular how the planning of such a concept can be designed and how the implementation of the concept as well as its financing can succeed. In order to be able to test approaches in practice, the project EW-K2 has excellent practical partners for the selected questions in the Fontane City of Neuruppin and the local municipal utilities. Since the Fontane City has already been working on the design of a climate-neutral municipal energy and heat supply for some time, it has a pioneering role to play. On the one hand, Neuruppin can share valuable experience gained from the steps already taken. On the other hand, Neuruppin is already asking pioneering questions that will also arise in a similar form in many other municipalities in the future.
