You can find a lot of community energy projects in our database. In Germany the focus so far was on the federal state of Schleswig-Holstein. We are currently working on including projects from all over Germany as well. Thereby, cooperatives form a large share of the projects. During our research we found an excellent set of case studies that was bundled into a publication. It is relatively easy to organise a cooperative for realising a solar PV project for example, especially when the municipality provides a rooftop and leads the process. In the publication different modes of cooperation between municipality, citizens, users, capital providers, landlords, service providers and energy providers in different cooperatives for different types of projects are explained. The publication is only available in German though.
