The energy will be produced at Ruswarp weir by the installation of an Archimedes screw, driving an electric generator with a 50kw capacity.

Facts and figures
- 50kW Archimedes Screw Hydro Powered Turbine
- 2.9 metres diameter
- 12 tonnes
- 1.8 metre head
- 4 tonnes water per second
- 6 to 27 revolutions per minute
An independent study of flows at the site, in 2012, estimated that approximately 160,000 kilowatt hours of electricity could be produced, equivalent to the electricity needs of about 45 houses, reducing carbon emissions by about 70 tonnes per year. This was then revised once the turbine was commissioned and during the first 5 years of operation (2012-2017) we have generated approximately 120,000 kWh / annum or approximately enough energy for 40 homes, reducing carbon emissions by about 65 tonnes per year.
