The San Martino University Hospital is the largest medical facility in the city of Genova. Internal electric power distribution takes place via a 15 kV Medium Voltage grid, connected to the ENEL distribution network via two Points of Delivery (PoD). Two co-generators were installed for a total of 3 MW generation capacity. Loads add up to a total of 4 MW. The network has a ring configuration and it is composed of 14 MV/LV cabins working in an in-out configuration. The San Martino hospital has implemented a real time energy monitoring system. The system is used as a tool to supervise energy demand at every MV/LV cabin and to support the management policies of buildings and technical facilities, in order to optimize energy consumption by pursuing energy saving opportunities. This paper presents how the real time monitoring system was implemented interfacing directly the MV protections. It presents the process of assessing the consumption profiles of the hospital facilities, in order to highlight issues and identify the actions to reduce energy waste. A specific case study is developed and conclusions drawn as to how a monitoring system can supply its users with a tool to improve efficiency and reduce costs.
