Towards a participatory energy transition. Critical issues and potentials of regulatory and financial instruments for Renewable Energy Communities (RECs) in Italy

The energy transition towards an economic model based on energy from renewable sources is considered a priority of strategic importance for the development of the European Union and Italy. In this context, Renewable Energy Communities (RECs) represent an opportunity to accelerate the decarbonisation process, to increase energy self-consumption and to replace centralised and hierarchical power plants with distributed and collaborative ones. This study aims to analyse how decarbonisation objectives are incorporated into national and regional regulatory and financial instruments that support the establishment of RECs. Starting from the comparison between the characteristics of REC and those of other energy community models with respect to a plurality of spheres (specifically, environmental, legal, economic-financial, technical, social and administrative spheres), the study provides a systematised framework of the advantages/disadvantages that influence the decision to invest in setting up a REC, and identifies the main critical issues that must be differentially addressed by the promoters, depending on whether they are public or private actors, assessing them through a system of nomenclators obtained following a focus group of experts. Furthermore, the analysis of regulations and available data on active RECs showed that Local Administrations play a central role in the dissemination of RECs, but also that the implementation of a sustainable and inclusive energy transition in the territories is hindered by a low level of social participation due to lack of knowledge of the benefits provided by RECs as well as actual difficulties for citizens to access REC projects, especially in their role as promoters.
