An IOA response to the Government consultation on updating guidance on the assessment and rating of onshore wind turbines - ETSU-R-97 - has been drafted by members with expertise in the assessment of noise and vibration from wind farm projects, and policy development. Input from members was also sought through a meeting and questionnaire. The Department for Energy Security and Net Zero state that the aim of this technical guidance is to provide advice to local authorities on appraising planning applications for onshore wind; aid the deployment of suitable wind developments and ensure noise is robustly controlled. Over the years working practice has evolved, coupled with the increased height of modern turbines. The IOA therefore welcomes a review of this guidance, and looks forward to working with the Government to ensure the supporting IOA good practice guidance reflects any policy changes that are adopted. 

The IOA holds no position on the value of the proposed noise limit as this is considered a matter of policy for Government. Nevertheless, the various individual opinions of our members on the noise limit are reported in our response for completeness.  The IOA has a long history of providing support to members for the application of the ETSU-R-97 methodology, and has published a number of relevant guidance documents on noise from wind turbines - which are listed in our response.
