  Renewable Energy Communities (RECs) have been officially introduced into the
European legislation through the Clean Energy for all Europeans package. A REC
is defined as an association of citizens, commercial activities, enterprises,
and local authorities that own small-scale power plants based on Renewable
Energy Sources (RESs). The community has the objective of maximizing the share
of renewable energy, i.e. the self-consumption of the energy generated by the
community RES power plants and to generally optimize the use of electrical
energy. This paper describes the ComER project, developed by the University of
Cassino and the Campus Bio-Medico University of Rome. The project focuses on
the main technical problems to face for the realization of a REC. The principal
objective is to develop methods and tools necessary for the management and
control of RECs. In particular, this paper describes the rules established for
RECs in the Italian legislations, the organization of the ComER project, the
adopted solutions and the first obtained results.
