In the last decades, European countries shifted towards decentralized energy generation, which is a crucial step for enhancing the diffusion from centralized power systems to smaller-scale systems. These small-scaled systems include local energy communities (ECs). The renewable energy communities (RECs) have a significant role and potential in this energy shift. Starting from the fact that using renewable energy sources (RES) reduces greenhouse gas emissions and the dependence on fossil fuels, the RECs are effective bodies, in means of scale and management, for the implementation of sustainable urban territories. This work analyzes different EC scenarios, considering energetic and economic perspectives. The energy concern is associated with improving the self-consumption and self-sufficiency indexes, while the economic concern is associated with the received incentive for each designed EC.
