As some of you know I have an unnatural interest in old hydros and am currently undertaking a heritage lottery funded research into the pre war hydros (there are hundreds!) As a follow-on from the new Craflwyn 100kw hydro receiving its planning permission last week i thought i would have a look for the old Craflwyn system. The new hydro is not the only one in the Craflwyn area. The site has two previous systems of which their remains can be seen. The Hafod y Porth system which shares the river (Afon y Cwm) with Craflwyn (the old weir site just happens to be the same area for the new hydro) The Craflwyn hydro is a much more elaborate system with ornamental ponds, man-made waterfalls, leats, sluice gates and such like. It used to power an old timber mill. As the old Welsh saying goes. “Haws cynna tan ar hen aelwyd” Its easier to light a fire on an old hearth. Old hydro sites can mean new hydro sites.
