According to DECC there's no Hydro Project at Avoncliff
Just an observation - the on-line DECC Renewable Energy mapping (data courtesy of The Environment Agency one has to assume) at http://restats.decc.gov.uk/app/pub/map/map/ shows no hydro project at either Avoncliff or Kingston Mills in Bradford on Avon.
The Freshford scheme at Farthingham weir is in there though...
Avoncliff invisible then? Now why might this be? I'm sure it's just a simple oversight.
