The installation of an Archimedes screw hydro-electric turbine in the River Wandle is now complete and is generating electricity. The screw, manufactured in the Netherlands, arrived at the park in July 2012.
In September 2012, the sluice gate was lifted, releasing the water into the screw. The long-awaited moment was watched by park volunteers as the screw began to turn. The turbine will generate enough electricity to power our new award-winning visitor centre.
The Final Phase
The turbine installation is the final phase of an exciting 2-year project to transform our semi-derelict stable yard into a vibrant new visitor centre, which will be the most energy-efficient historic building in the country.
The turbine will contribute to our energy needs, which are also being met by three different sorts of solar panels, an air source heat pump and a wood burning stove.
The Archimedes screw was installed in the River Wandle, behind the Grade II listed Snuff Mill and the original waterwheel, which was also conserved last year.
A modern waterwheel
The turbine acts as a modern waterwheel, harnessing the power of the river to generate electricity. It is estimated that it will generate 59,000 kWh a year – about 12 times as much electricity as an average household uses.
The renovation project has been supported by a Heritage Lottery Fund (HLF) grant. The Archimedes screw turbine phase of the project is also being funded by City Bridge Trust and Thames Water.
The Archimedes screw turbine was installed by Mackley Construction and Hallidays Hydropower.
