In response to the ongoing climate crisis, the European Union has introduced a legislative package aimed at promoting clean energy initiatives. In this context, energy communities (E C s) are defined as core actors in the energy transition plan, by promoting local electricity generation, consumption, and sharing. This study aims to investigate the feasibility of E C s in Sweden, by performing a case study on a real distribution system in a Stockholm district. Solar photovoltaic (P V) and energy storage (E S) technologies are modeled and implemented into the system, and different scenarios are tested to identify optimal techno-economic solutions. The results indicate that self-consumption can increase up to 95%, and annual electricity costs are reduced by up to 30% compared to a case without PV generation. The analysis of the net present value (NPV) shows that collective self-consumption through shared solar applications increases the profitability of investing in PV by more than 24%.
