The concept of Energy Community is currently beginning to be appreciated by non-experts. Until about a decade ago, electricity generation was exclusively centralized and mostly run by fossil fuels. the power produced would then reach people’s homes through high, medium, and low voltage networks. Today, with small-scale plants, energy generation has become increasingly local and clustered near the consumption places, particularly thanks to the spread of photovoltaic systems, which are versatile in their application and have very few limitations in geographical distribution. Recently, other renewable sources small-scale plants have been developed for local and domestic use, greatly reducing losses related to transportation and distribution. In this context, one of the main objectives of the Energy Communities is to maximize and, therefore, stimulate both prompt and proximity self-consumption with appropriate incentives like State and European funding.
