ASH undertook a Landscape and Visual Impact Assessment for the proposed Hafod-y-dafal wind turbines

ASH was appointed by Savills on behalf of Airvolution Energy to undertake a Landscape and Visual Impact Assessment in support of a planning application for the development of two wind turbines at Hafod-y-dafal Farm, near Abertillery, Blaenau Gwent, South Wales.

Key Tasks

Landscape and visual impact assessment

Cumulative landscape and visual impact assessment



Residential amenity study

Public consultation


What we did

Following the generation of a Zone of Theoretical Visibility diagram and a preliminary site visit, ASH identified a series of viewpoint locations from which photomontages of the proposed development would be created. The viewpoint list, which included settlements, popular outdoor locations and views from the Brecon Beacons National Park, was issued to the Local Planning Authority and Natural Resources Wales for consultation.

ASH was responsible for undertaking the photography from all viewpoint locations (a total of 24). The photography was used in the preparation of photomontages using our specialist graphics modelling and visualisation software.

A cumulative assessment was carried out which considered the potential impact of the proposed turbines when viewed in combination with all other submitted wind turbine applications, consented and operational wind farm sites within 60km of the proposed development.

ASH prepared the landscape and visual chapter for inclusion in an Environmental Appraisal. The planning application was submitted during October 2013. Consent was refused and a planning appeal was held in June 2015 at which ASH acted as expert witness on landscape and visual issues. Unfortunately the appeal was unsuccessful.
