Lambro Milano Crescenzago is a low-head hydro plant with a flow rate of 15.000 litres per second after a 2,1 meter drop. Situated in the administrative territory of Lombardy’s capital and built upon a former irrigation channel, it offers a great peculiarity: three innovative screw turbines. Thanks to this plant we can produce clean energy in an area which is both highly anthropized and environmentally compromised.
