What is cogeneration?
Cogeneration is the combined process of producing electricity and heat. In traditional thermoelectric plants, only a part of the energy contained in the fuel is converted into electricity. The remaining part, about 60%, is dispersed in the form of heat.
In a cogeneration plant, this heat is recovered and used in industrial or civil processes (e.g. district heating).
Cogeneration plants improve efficiency in the production of electricity, reduce the consumption of primary energy (fuel) and consequently reduce the emission of pollutants into the environment.
Our cogeneration installations are located at the Biassono, Villasanta, Arcore and Felino plants.
Since 2014, the Biassono cogeneration plant has generated approximately 10 GWh of electricity a year and fully uses the heat it generates (e.g. sanitary water, cold room defrosting, cooking, pasteurization, etc.).
Since 2016, a high-efficiency cogeneration power plant has also been operating at the Villasanta plant. In fact, Rovagnati produces both electricity, which is essential to meet the needs of the Villasanta plant, and thermal energy. Today, the Arcore and Felino locations are equipped with the same plants.
The plant transfers the heat it produces to Acsm Agam, feeding it directly into the Monza district heating network (DHN). This allows us to supply the city of Monza with the heat to meet the needs of 31 large apartment buildings.
