Spaans Babcock is in the process of installing two huge Screw Generators within the boundary of the Lake District National Park, at the Southern end of Lake Windermere. The equipment is to be installed at the site of a former gunpowder works in Low Wood, Haverthwaite and will use water from the River Leven.
Each screw has a diameter of 3 metres, is 19 metres long and weighs around 40 tonnes. They have a combined power output of over 400 kW when operating at their full capacity of 4,000 l/s each. This capacity and the head of 7.2 metres make it one of the largest Archimedes screw hydro power stations in the World. The largest being Teesside which has four screws, generating a combined power output of 520 kW - also supplied and installed by Spaans Babcock.
