Entwicklung und Stand von Bürgerenergiegesellschaften und Energiegenossenschaften in Deutschland

In the paper, the authors describe an estimation of the number and development of community energy companies and energy cooperatives in Germany. The analysis is based on two databases that are maintained by the authors. An increase in the number of new community energy companies in Germany can be observed until 2014. In 2014 at the latest, the number of newly founded energy cooperatives decreased. The decline could only partly be compensated by an increase in the number of limited partnerships with a limited liability company as general partner (GmbH & Co. KG). This shift from the cooperative model to the limited partnership model is linked to a shift in the predominant electricity generation technology. An increase in onshore wind energy can be observed while photovoltaics had to struggle with a shrinking market. Moreover, more bankruptcies and liquidations have been observed since 2009 for community energy companies and energy cooperatives. The existing community energy companies are mostly producing electricity while only a smaller group runs energy grids, especially for heat distribution (small district heating networks). The main focus of community energy companies and energy cooperatives lays on the production of energy through onshore wind and photovoltaics. Bavaria, Schleswig-Holstein, Lower Saxony and North Rhine-Westphalia are the regional core areas of these companies
