Case Study 2 – Communities of Actors

The concept of optimizing local PV self-generation and consumption on ‘prosumers’ level is already well established in many European countries. Recently, a further development of this concept beyond individual prosumer boundaries to neighbourhood and district level has been triggered not least by the ‘EC Clean Energy Package’ (the establishment of energy communities and further ‘democratization’ of the energy system is explicitly mentioned). Moreover, favourable amendment of legislation and regulations in this context have been made in some European countries (e.g. Germany, Austria).


  • Participation is on a voluntary basis: fully democratic participation, considering the individual needs of the actors
  • Diversity of actors involved with different individual objectives
  • Different manifold, e.g. in terms of renewable technologies, system boundaries (building level, spatial extent, distribution grid anatomy, peer-to-peer matching/trading in a wider context, etc.)
  • No self-sufficiency of the community is intended
