On May 31st, 2024 the students of the course “Power generation systems” (lecturer: prof. Paolo Colbertaldo) of the MSc in Environmental and Land Planning Engineering participated to a visit to the trigeneration power plant of Campus Leonardo of Politecnico di Milano. Dr. Filippo Bovera showed the system and the control room, discussed the system layout and features, with a focus on the energy efficiency advantages of generating electric power, heating, and cooling in a combined manner. The trigeneration plant exploits a modern 2 MWe natural gas-fed internal combustion engines, and it is regulated according to the campus demand, interacting with the electric grid and with the intermittent power supply from solar PV systems, which are progressively installed on many buildings’ rooftop.
