Stuck are about 2,500 consumers who believed in "energy democracy" and invested to become self-producers, i.e. to produce the electricity they consume themselves by using the institution of Energy Communities. At the same time, apartment buildings that have used the "Execonomo" actions and installed a communal heating system with heat pumps are "punished" with high energy prices. They are charged on the basis of the C1 business tariff, which is more expensive than the residential tariff, because, according to the provider, in order to change these services to residential use, they will have to pay ENFIA for the common areas. Energy Communities are a European institution that has been successfully used in many EU countries in the context of the strategy of transition from fossil fuels to renewables, enabling groups of citizens and local actors to produce green energy for their own consumption. In Greece, this path was opened with Law 4513/2018 and since then, over a period of six years, additional legislative interventions have followed to correct distortions that had led to the abuse of the institution by companies that exploited the privileges of the institutional framework (priority connection to the grid, etc.) and its harmonization with European directives. Thus, although there are currently around 1 400 Energy Communities registered, only around 60 belong to the category of self-consumption. These are mainly made up of households, small businesses and associations, while some of them also include municipalities and have around 2 500 members. Today, two and three years after the investments have been completed, they have no financial benefit to pay for them.
