Project: Binga Fea Wind Farm Cumulative Noise Impact Assessment
Client: Binga Fea Wind Farm Ltd
Before achieving planning consent to add two new 900kW turbines to an existing one already operated by the community of Hoy in the Orkney Islands, Binga Fea Wind Farm Ltd needed to prove that the cumulative noise impact of all three turbines fell within acceptable limits as specified by ETSU-R-97.
24 Acoustics were therefore retained by the client to carry out a cumulative noise impact assessment. In order to achieve this, it was first essential to establish “true” background noise measurements at receptor properties – those which were not affected by noise emission from the existing turbine, which therefore had to be shut down for the duration of the three week survey.
With three turbines run by two different operators, thereby making enforcement of planning condition noise limits more complicated, 24 Acoustics worked closely with the operator of the existing community turbine, the client and the Orkney Isles Council Environmental Health officer to achieve a solution acceptable to all parties, with planning consent granted in late 2012.
