The water-wheel at Aberdulais Falls viewed at ground level

Hydro systems have been used for centuries. At Aberdulais Falls, the water wheel was used for milling. Now, it’s the largest electricity-generating water wheel in Europe.

Did you know? You’ll need permission from the Environment Agency and neighbouring landowners if you want to build a hydro turbine. The location of your turbine will depend on water flow, height and environmental restrictions.

We’ve built our first large-scale hydro at Hafod y Llan farm in Snowdonia.
