A RESTORED 18th Century watermill has generated a million kilowatt hours of green power through a combination of traditional and new technology.

Howsham Mill, near Malton in North Yorkshire, is run by the charitable Renewable Heritage Trust and has been generating hydroelectric energy since the mid-2000s.

And this week its online meter, which shows how much green power has been generated, ticked over to 1,000,000kWh - six years, 11 months and 13 days after the screw turbine was connected to the grid - enough to boil 60m full kettles.

The mill was the first venue in the country to use the new Archimedean screw technology, installing a 20kW scheme in 2007 and the trust is currently installing a second 40kW screw.

Dave Mann of MannPower Consulting, which installed the screw, said: “This is a fabulous example of how old and new technology can work alongside each other.”
