Further site investigation revealed that any revised designs to eliminate noise issues would result in a project that would not be big enough to meet the company’s criteria for wind farm developments.

The proposed 10MW project, which was being developed jointly with local community group, the Arts Factory, originally received planning consent in 2005.

In Wales, E.ON already operates Rhyd-y-Groes, a 24-turbine onshore wind farm on Anglesey and Rheidol, an eight turbine wind farm in Ceredigion. E.ON is also building Robin Rigg in the Solway Firth, which at 180MW is expected to be one of the largest offshore wind farms in Europe.

Danny Shaw, head of new business for E.ON, said: We certainly did not take this decision lightly but, as a responsible developer, we simply would not be willing to build a scheme that we thought had the potential to exceed acceptable noise limits. We have looked at a number of solutions to make this project work but, ultimately, we have determined that the largest scheme possible for the site would be under 5MW, which is not big enough to meet our criteria for new onshore wind developments.
