Self-Consumption Configurations for Renewable Energy Sharing in Condominiums (CACERs)

The growing trend of on-site energy production, particularly through photovoltaic (PV) systems in apartment buildings and condominiums, presents a significant challenge: efficiently distributing the generated electricity amongst individual units. This study explores Self-Consumption Configurations for Renewable Energy Sharing in Condominiums (CACERs) as a solution to this hurdle and introduces a proposal model of power sharing as alternative model. This shift towards decentralized energy production aligns with the growing emphasis on empowering passive consumers. Recent European Directives highlight the importance of active end-user participation in the energy system, which includes residential, commercial, and tertiary buildings - substantial contributors to overall energy consumption. These 'end-users' can become active participants either directly or through collaborative aggregations. To address the challenge of energy distribution within condominiums utilizing CACERs, this paper provides a comprehensive overview of the current state of CACERs in Italy. A case study of a typical urban condominium serves as the reference for this analysis. The study explores energy and economic assessments for the condominium, focusing on both the CACER and Power Sharing models. This analysis will provide valuable insights into the feasibility and benefits of these CACERs for condominiums in Italy.
