Maurizio Delfanti obtained his master’s degree and PhD in Electrical Engineering from the University of Pavia. Since 2001, he has taught in various roles (researcher, associate professor, full professor) at Politecnico di Milano. From 2019 to 2023, he was CEO of RSE (Ricerca Sistema Energetico). Since 2024, he has been a full professor in the Department of Energy at the Politecnico di Milano, where he coordinates the University Energy Commission. Since 2025, he has represented the Politecnico on the board of directors of LEAP (Laboratorio Energia e Ambiente Piacenza). His research activity is evidenced by more than 120 scientific articles on electrical energy systems. Initially, his research focused on the planning and management of transmission systems, with an emphasis on voltage security and network congestion. With the introduction of the electricity market in Italy in 1999, he studied issues related to liberalised systems, with an emphasis on economic aspects and service quality. The latter area was investigated with reference to both technical and regulatory aspects, in close collaboration with the sector’s regulatory authority (ARERA), participating in the analysis of the electricity disruption of 28 September 2003. Since 2010, Maurizio Delfanti has investigated the impact of distributed generation on medium and low voltage electricity network infrastructure, contributing to the evolution of distribution systems from passive to active. In this context, he has participated in numerous standardisation and regulatory activities at national and international level, contributing to the definition of technical rules for the connection of active and passive users to distribution networks. In this context, the expertise gained in research activities has been applied to technical standardisation, serving as Chairman of CT 316 (connection to high, medium and low voltage electricity distribution networks) and Technical Secretary of CENELEC TC8X (System aspects of electricity supply). Also in relation to ARERA’s activities, he has worked on the technical and economic optimisation of storage systems, following prototype applications at national level (TERNA storage, energy-intensive and power-intensive projects) and investigating the participation of batteries in energy markets, as well as the integration of renewable sources and electric charging infrastructure into networks. Recently, attention has turned to the evolution trajectories of energy systems, with medium- and long-term scenario projections.
