The European Union has set ambitious targets to move towards a society with high penetration of renewable energy sources. In the forthcoming energy transition, Energy Communities (EC), i.e., legal entities where different actors, including citizens, cooperate in energy generation, storage and management, will play a crucial role. The present work simulates the energy flows and assesses the potential economic benefits of a cluster of buildings acting collectively as an energy community – a specific case study is set in northern Italy by comparing the EC performance with a configuration where customers act as Single Self-Consumers (SSCs). Pending the transposition of EU Directives to binding national laws, due by 2021, different supporting tariffs (economic scenarios) have been simulated in order to determine which scheme will support more effectively the integration of Energy Communities in the national energy market. Results show that ECs (i.e., customers acting collectively as energy prosumers) are able to accelerate the diffusion of building-integrated renewable energy sources (RES), resulting in higher overall self-consumption rates than SSCs. Self-consumed electricity generates savings on the energy bill of EC, and we calculated positive economic performance indicators for all the analysed economic scenarios. The sensitivity analysis carried out on system and transport charges of the electricity bill shows their remarkable impact on the economics making the EC less attractive for investors and citizens without proper supporting schemes.
