An Bord Pleanala has overturned a decision by Offaly County Council to grant planning permission for ten wind turbines in Cloghan.
The wind farm plan was turned down mainly due to significant visual intrusion, as it was deemed that the plan would have an adverse affect on residents in the area.
The proposed wind farm was to be located just one and a half kilometres from Cloghan, and An Bord Pleanala heard that another 34 houses were located two and a half kilometres away from the farm.
The National Roads Authority had raised its concerns over access to the site and implications for traffic during construction.
The height of the turbines was raised by An Bord Pleanala as too high for the surroundings.
The ten turbines - at 25 megawatts – were deemed to be too high at 550 feet high.
