Socomec has equipped the Trieste-Friuli-Venezia Giulia Airport with photovoltaic panels and three battery storage systems, enabling the airport infrastructure to reduce its reliance on the electricity grid to just 30% of its annual consumption. The project integrates three modular Sunsys HES L storage systems, connected in parallel to achieve a power of 600 kVA and a capacity of 3.3 MWh. Socomec's Power Management System optimizes battery charge and discharge cycles based on real-time photovoltaic production and site electricity demand. This initiative has transformed the airport's energy mix, with 70% of its needs now covered by self-consumption, including 46% from the solar plant and 24% from batteries, reducing direct CO2 emissions by 559 tons annually. The storage system also facilitates the charging of 42 electric vehicles overnight without grid upgrades, contributing to the electrification of 75% of ground vehicles and a reduction of approximately 14,000 liters of diesel consumption per year.
