AGL Energy (AGL) has announced the Macarthur Wind Farm is successfully operating within the strict noise limits set in the wind farm’s State Planning Permit, as evidenced in the Macarthur Wind Farm Noise Compliance Assessment independently produced by AECOM Australia.
The Planning Permit, which is enforced by the Victorian State Government, required pending landowner approval to be carried out at specified dwellings neighbouring the Macarthur Wind Farm.
Noise loggers were installed between February and March 2013 to capture the noise data for this objective assessment.
This Noise Compliance Assessment is part of a wider noise monitoring program implemented by AGL since the first turbines started operating in late September 2012.
All noise monitoring results received to date at 13 neighbouring dwellings demonstrate the Macarthur Wind Farm complies with the acoustic requirements of the Planning Permit.
AGL group general manager power development Scott Thomas said the company is pleased the independent assessment demonstrates the Macarthur Wind Farm continues to operate well within the Planning Permit requirements.
“We appreciate some community members have been concerned about wind farm noise levels so we wanted to make sure it was operating correctly from the start and give the community a greater level of comfort,” Mr Thomas said.
“Over 40,000 hours of noise monitoring has been conducted at Macarthur, which is well beyond the amount of noise monitoring required in the Planning Permit.”
The Planning Permit requires the noise level from an operating wind farm, measured outdoors of a dwelling at any relevant nominated wind speed, shall not exceed the background noise level before the wind farm was operating by more than five dB(A) or a level of 40 dB(A), whichever is higher.
The combined noise levels were assessed at 10-minute intervals at the specified dwellings. Compliance was assessed throughout the entire day, and separately at night when the background noise level is typically lower.
The testing also monitored for special audible characteristics (clearly audible tones, impulses, or modulation of sound levels). Special audible characteristics were not determined to be present at any of the noise monitoring locations.
