I live in close proximity to the Bald Hills Wind Farm and have serious concerns regarding the noise produced by the wind farm and the manner in which they are operated.
Since their start-up I have observed their operation and the noise produced by the turbines which has been horrendous.
I have also contacted in writing the South Gippsland Shire expressing my concern to which they have replied.
I have contacted the BHWF in writing with my concerns of the noise level and their manner of operation to which I have not received a reply.
The BHWF has been positioned near dwellings as close as 500m and a number of others less than 1500m. This is absurd, irresponsible and in particular unnecessary and has had a significant impact on people and community.
One cannot appreciate the impact of the turbine noise unless one lives in close proximity to the farm 24 hours a day under constantly changing environmental conditions.
Analytical noise measurements are important and provide useful data indicating troublesome noise issues, however this data cannot interpret the actual conditions experienced by people living these conditions.
The current public dilemma associated with wind turbine farms could easily be alleviated by designating a clear and proper separation distance between dwelling and turbine.
In my opinion wind turbine farms should not be permitted to be in a location within three to four kilometres of a dwelling.
This simple technique has been ignored by the statutory authorities and as a consequence has created justifiable public concerns and the authorities should be held accountable for these poor management decisions.
I have observed the turbine operation since their start-up in March 2015 and the disturbing noise generated under significantly varying environmental conditions.
They have a remarkable ability to operate under dead still ambient conditions and approaching maximum rotational speeds. The noise generated under these conditions is horrendous. I have observed their operation under medium to high wind conditions and the noise level is noticeably less. Wind turbine blades are aerodynamically designed to be driven by the wind producing low drag forces resulting in low noise. When they are being used as motors, not generators, the blades act as fans and are aerodynamically inefficient resulting in horrendous noise levels.
I believe the turbines are being used in conjunction with the power generators to shed excess load during low demand periods and to maintain steady coal fired generator loads.
Industry experts claim wind turbine farms located in ideal locations have a 30 to 40 per cent utilisation. I estimate of the BHWF utilisation is in the order of 80 to 90 per cent. An explanation for this discrepancy is appropriate.
I believe it is in the public interest the operation and agreements made with third parties be made public.
An independent audit should be conducted by the Ombudsman for Energy to determine the energy produced thus far from the BHWF and the energy absorbed by the BHWF. This can simply and easily be obtained from AUS Net who operate the power distribution network.
I believe there is a misconception of the BHWF operation and defeats the purpose of alternative energy if used for other commercial purposes.
I base my findings on detailed observations, calculation and over 30 years of experience as a professional mechanical engineer.
