Business continuity and efficiency are recognized as key factors for the development of port electrical distribution systems. On one hand, the electrical system has to ensure safe, reliable and redundant supply of port loads and facilities: this constitutes a compulsory and imperative requirement for ensuring the port operation thus guaranteeing the related business. On the other, the port loads are to be efficiently fed for limiting power losses, therefore avoiding wasteful costs and implementing de-carbonization actions. To these aims, the paper models part of the electrical distribution system installed in the Port of Trieste (Italy). The latter is analyzed for identifying hidden power losses and defining the capability for new electrical installations. Particularly, the last aspect is of paramount importance considering the interest in installing electrical hubs for enabling locomotive/vehicle charging and shore-to-ship connections.
