Noise Monitoring Program

To date, over 40,000 hours of noise monitoring has been conducted at the Macarthur Wind Farm, which is well beyond the amount of noise monitoring required in the Planning Permit. We are pleased to advise that all noise monitoring results received to date at 13 neighboring dwellings demonstrate that the Macarthur Wind Farm complies with the acoustic requirements of the Planning Permit.

The Government's strict noise regulations for the Macarthur Wind Farm are in line with the World Health Organisation's guidelines for noise limits.

AGL has engaged fully accredited noise acousticians to carry out the monitoring and all noise monitoring has been conducted in accordance with the relevant Standards. In the interest of transparency, all relevant raw noise data collected from this monitoring is being provided to the landowners for their records.

To confirm that the wind farm continues to remain compliant with its noise requirements under the planning permit, AGL is required to complete two rounds of noise monitoring across several locations surrounding the wind farm. The first round of noise monitoring was conducted in early 2013, and the final round was completed in early 2014, with  all results demonstrating compliance was achieved.

A copy of the Background Noise Assesment Report can be found here. The first Noise Compliance Assessment Report for noise monitoring completed in 2013 can be found here. The final Noise Compliance Assessment Report for noise monitoring completed in 2014 can be found here.

Infrasound and Low Frequency Noise Monitoring

An independent report by Resonate Acoustics demonstrates that there was no measurable change in the infrasound levels measured before and after construction of the Macarthur Wind Farm. The report titled Infrasound & Low Frequency Noise Operational Monitoring was reviewed by internationally renowned low frequency acoustic expert, Dr Geoff Leventhall. AGL voluntarily commissioned this report to help alleviate community concern regarding noise. View the report here.

The aim of the assessment was to compare measured infrasound (noise at frequencies lower than 20 Hz) and low frequency noise (noise from frequencies of 10 Hz to 160 Hz) levels between the measurement stages as well as to relevant assessment criteria.

Indoor measurements of infrasound and low frequency noise levels have been conducted at residences located 2.7 and 1.8 km from the nearest turbine during the following stages:

  • pre-operational: no WTGs operating
  • interim: approximately 105 out of 140 WTGs operating
  • operational: all 140 WTGs operating

The assessment has demonstrated that infrasound and low frequency noise levels from Macarthur Wind Farm are compliant with relevant assessment criteria at the two nearby residences.

Macarthur Wind Farm complies with strict permit noise limits

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 Pty Ltd (AECOM). 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.

View the Noise Compliance Assessment report Part A and Part B that has been conducted in accordance with the relevant Standard and submitted to the Victorian Government for review.

The Planning Permit, which is enforced by the Victorian State Government, required that pending landowner approval, noise monitoring was to be carried out at specified dwellings neighboring the Macarthur Wind Farm. Noise loggers were installed between February and March 2013 to capture the noise data for this objective assessment.

The Planning Permit requires that 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.

Additional noise monitoring beyond the permit requirements

In addition to the noise monitoring required in the Planning Permit, extra noise monitoring was carried out at the Macarthur Wind Farm since the first turbines started operating on 30 September 2012. All results received confirm the wind farm remains compliant with the strict noise limits set in the Victorian Governments Planning Permit. View the monthly noise monitoring reports below.

Bat and Avifauna Monitoring Program

AGL has carried out an extensive bat and avifauna monitoring program at the Macarthur Wind Farm. The monitoring has been conducted over two years by Australian Ecological Research Services. Reports for the second year of monitoring can be found below.

Bat and Avifauna Mortality Monitoring

AGL has carried out an extensive two-year bat and avifauna mortality monitoring program at the Macarthur Wind Farm. The primary aim of the monitoring program is to assess bat and avifauna mortality resulting from collision with the blades of wind turbines, with a particular focus on threatened species known to occur within the region. Results at the end of the two year period have found effects on populations of threatened species are likely to have been negligible. The report prepared by Australian Ecological Research Services for March 2014 – February 2015 can be viewed below.

Key findings from the two—year monitoring program include:

  • Only two individual collision mortalities of listed threatened species were detected during two years of intensive monitoring at Macarthur Wind Farm. These were a Black Falcon in 2013 and a Southern Bent-wing Bat in 2014.
  • The birds that collided most commonly with turbines in 2014 were introduced Eurasian Skylarks.
  • The annual mortality of all native birds in 2014 was estimated at 3.31 ± 0.78 per turbine.
  • Amongst native birds, species of raptors were more prone to collisions that any other group of birds. This finding is consistent with other wind farms in southern Australia.

Macarthur Wind Farm Brolga Monitoring Report

Australian Ecological Research Services have undertaken post-construction monitoring of Brolga’s within the vicinity of the wind farm for two years. The following report details the results of the second year of Brolga monitoring undertaken during the breeding season of 2014. Details of the presence, behaviour and movements of the Brolgas found within the vicinity of Macarthur Wind Farm are discussed in the report. Results from two years of monitoring the Brolga, have found the Macarthur Wind Farm does not appear to have had any detrimental impact on the local Brolga population, either from direct impact with turbines or displacement from habitat. There have been no Brolga collisions with turbines and Brolgas have successfully bred on the wind farm and continue to return to the site each year for the breeding season.

Bat Activity at the Macarthur Wind Farm

Australian Ecological Research Services Pty Ltd have undertaken a two year bat monitoring program to assess bat species present on the wind farm and their relative activity. As advised by the Department of Environment, Land, Water and Planning (formerly Department of Sustainability and Environment), monitoring was timed to coincide with the migratory periods of the Southern Bent-wing Bat in early autumn and late spring. The following report details the results of the autumn and spring 2014 monitoring periods, documenting the bat species recorded and examines their relative activity between species and at different locations within the wind farm. Overall bat activity was compared with that recorded during autumn and spring 2013 to examine changes in activity.
