The energy transition towards a more sustainable and fossil-free energy system still faces several challenges. In fact, the transformation from the current system to a decentralized renewable energy system requires a successful involvement of the communities to remodel the current energy production. As a solution, Renewable Energy Communities (RECs) can involve the stakeholders in an active financial participation labelled Consumer Stock Ownership Plans (CSOPs). By acquiring co-ownership in RE, the model places the stakeholders as producers and consumers of the system, making them "prosumers". Along these lines, an ongoing EU Horizon 2020 project called "Supporting Consumer co-Ownership in Renewable Energies" (SCORE) seeks to overcome the energy usage of fossil sources by promoting the creation of RECs and facilitating co-ownership, focusing on the inclusion of vulnerable groups.
