This study sets out to analyse how Energy Communities are currently implemented in Norway, Sweden, Finland and Denmark, and furthermore looks into similar models in three other European countries. In relation to Energy Communities, Nordic Energy Research (NER) also wants to investigate questions linked to market access, grid ownership and operation, and tariffication. The overall objective of the study is to support the Nordic authorities in their implementation of the requirements of the Electricity Directive (Article 16), to support the exchange of views on lessons learned and to profit from the common experiences in the Nordic and European countries.
