The 92 kW Hydro Ness generator on the banks of the River Ness in Scotland is now fully operational, according to the Scottish Highland Council.
Hydro Ness is an Archimedes screw hydroelectric scheme, and interactive visitor experience, that will generate over 500,000 kWh of renewable energy each year.
The Archimedes screw turbine-generator consists of a rotor in the shape of an Archimedean screw – with a hollow cylinder and a spiral part on the outside — which rotates in a semicircular trough. Water flows into the screw and its weight presses down onto the blades, forcing the turbine to turn. Water flows freely off the end of the screw into the river. The upper end of the screw is connected to a generator through a gearbox.
