The document deals with the interaction between public and private electric mobility and the related distribution networks of an Italian metropolis from a technical and economic point of view. As regards public road transport, in view of the recent updates on the technical and economic potential of the adoption of electric bus fleets, the possible impacts on the electricity networks are provided based on the analysis of transport details and on a real experience at a national level.
Based on the research activities launched in previous reference periods of System Research, in-depth studies were carried out on the methods of managing energy supply, also considering the distributed generation existing on site to integrate the charging of private and public means. The results demonstrate the current adequacy of the present electricity networks, without however excluding a growing impact of the share linked to the charging of public transport, currently still modest, but potentially consistent in the future.
The second part of the report deals with rail passenger transport: it identifies currently non-electrified routes and the development programs of the major operators on this topic, and excludes routes already destined for hydrogen conversion. Following the technical reconnaissance on the subject of battery traction, with possible flash charging via pantograph, the report comes to the conclusion of a potential opportunity for adopting this typology.
The third part of the report focuses on maritime public transport. In this case the analysis focuses on the electrification of public transport vessels such as ferries, hydrofoils, etc. In particular, technical-economic considerations were carried out for routes already identified as “electrifiable” in the previous reference period, which proved to be viable.
The document concludes with a monitoring analysis on the evolution towards electrification of the remaining main forms of transport (air transport in particular).
