the energy of the future


Green energy, perfect harmony between technology and sustainability.

Simple and effective

Screw turbine

The screw turbine, also known as Archimedes' screw, is a volumetric turbine. Like the other types of turbine, it harnesses the hydraulic energy of a water resource flowing through a gradient to generate electricity. This type of machine is suitable for low or very low water levels.

Kaplan turbine

Macchina idraulica inventata nel 1913 dal professore austriaco Viktor Kaplan, la turbina Kaplan è una macchina a reazione adatta a salti idraulici medio-bassi e portate elevate. Ha un buon rendimento e un basso impatto ambientale. A hydraulic machine invented in 1913 by Austrian professor Viktor Kaplan, the Kaplan turbine is a reaction machine suitable for low to medium hydraulic jumps and high flow rates. It has good efficiency and a low environmental impact. The structure of the Kaplan turbine is complex and requires the installation of a speed increaser or a high-polarity generator using permanent magnet technology.

high performance, reduced maintenance

Pelton turbine

The Pelton turbine was invented by Lester Allan Pelton in 1870 in California. This type of turbine is an action turbine and exploits the transformation of the potential energy of water stored in reservoirs into kinetic energy. It is suitable for high geodetic jumps and low water flow rates.


Maximum efficiency

Francis turbine

The Francis turbine is a type of hydraulic turbine developed by James B. Francis in Lovell (Massachusetts, U.S.A) in 1848. It is a centripetal flow reaction turbine that combines the concepts of radial and axial flow. It operates with medium to high jumps and flow rates and is currently the most widely used hydraulic turbine. Francis turbines are the most efficient hydraulic machines, with a power per unit of up to 700MW.
