The thermal power station Regina Margherita was a large power station for the production of electricity, preserved at the Museo nazionale della scienza e della tecnologia Leonardo da Vinci in Milan, Italy. The station opened in 1895 and was originally installed in the Egidio e Pio Gavazzi silk factory in Desio (Milan), where it operated until 1954. It supplied electricity for lighting and for the operation of 1,800 looms, generating alternating electric current at a voltage of 200 V.[1]
