Please feel free to pass this information on to planning officers and encourage them to contact us direct. ### Planning Application for erecting a Proven Wind Turbine We now have over 200 installations in the UK supplying a diverse range of applications from hilltop telecommunications sites to domestic heating and electricity. In general planning officers and committees have little first-hand information or experience on which to base their decisions as regards small wind turbines (2-9 metre rotor diameter). They have all heard of the hullabaloo surrounding large commercial wind turbines (45-80 metre rotor diameter) and are wary of issues such as visual intrusion and noise. In practice, neither of these issues is a problem for small wind turbines - a recent domestic customer survey indicated that Proven customers would all be happy to have the turbine closer to their house than they have it at present. Present distances vary from under 10 metres to 150 metres: the turbine being sited for best wind resource. We have over 25 turbines in sensitive areas such as National Parks, nature reserves and other protected sites, see attached list for details. Please feel free to contact any of the people on our Reference Site List or to visit our test machine outside our factory at Stewarton. If these sites are too far away to visit we will contact our nearest customer to the proposed site and try to arrange a mutually convenient meeting. ![photograph from page 5](https://images.planningportal.im/2004/10/372142.jpg) Figure 1: Proven WT2500 (6.5m to hub) beside wind farm turbine (approx 40m to hub) See also scale drawine enclosed at end of this pack ## Proven Wind Turbines are about the same height as a standard telephone pole. ![Grainy black and white photograph showing a rural hillside with a wind turbine in the distance and a utility pole in the foreground.](https://images.planningportal.im/2004/10/372143.jpg) The Proven WT15000 wind turbine stands on a 15m pole (50') - not much bigger than a standard wooden telephone pole of which there must be millions in this country. Our installations often save the need for a new grid link requiring perhaps 10 or 20 of these wooden poles with attendant overhead lines trailing across the countryside. The windmill rotor blades are black and quickly merge into the background scenery. For example we have a turbine beside a house on the hill above the town of Largs in Ayrshire. Planners were initially concerned that it would be clearly visible from the town below. However, two and a half years after installation people in Largs town centre are generally unaware of its presence and once pointed out they struggle to pick it out at a distance of half a mile (it is difficult to see against the hill) and are not in the least threatened by it! ## Proven wind turbines are quiet Our wind generators are expressly designed to be quiet and people friendly. - They do not contain a gear box (the main source of whining noise in large wind farm type machines) - Our windmill blades have specially shaped tips to reduce any wind noise - The WT15000 runs at a maximum speed of 160 rpm - about half the speed of other similar small wind turbines. This means that the blade tips move at a much lower speed and the only sound is a gentle 'swooshing' noise. ## Measurements of noise in different wind conditions. Readings from the WT15000 in light and high winds are as follows. Background noise: The reading from my A.T.P. SL-25 Portable Sound Meter indicated 65dB(A) due to background wind noise plus noise from wind swishing through the small trees approximately 5m away. Windmill noise: Pointing my sound meter directly at the rotors while standing at the base of the machine produced a reading of 60dB(A), while a gentle swishing noise was heard. (Passing cars, moving at approximately 40m.p.h at a distance of 15 metres caused the readings to rise to between 70 and 80dB(A)). The noise in a gentle breeze (12m.p.h) 5m/s is around 40dB(A): again not more than the background wind noise level. Anecdotal Evidence Our test machine is situated 25m from the front door of our workshop. The main office is single glazed and we never hear it. However, we can hear the traffic on the B-road, a further 15m away, which has traffic moving at 30-50mph. Recent customers Mr and Mrs Chapman are delighted with how quiet their Proven Wind Turbine (address supplied on request). The attention to noise reduction at the design stage has, according to the Chapmans, reduced noise output to a level below that produced by their previous windmill, which produced only 100Watts maximum with a diameter of 0.9m! Note on planning advice on small wind turbines from SNH Scottish Natural Heritage has released specific guidance on location of wind farms in Scotland. This is contained in their policy statement "STRATEGIC LOCATIONAL GUIDANCE FOR ONSHORE WIND FARMS IN RESPECT OF THE NATURAL HERITAGE" to be read in conjunction with the National Planning Policy Guidelines on renewable energy (NPPG6). Paragraph 7 deals specifically with smaller wind turbines such as those manufactured by Proven and states that the special rules required for wind farms do not apply to small scale wind turbines:- "The guidance only applies to the consideration of onshore wind farms, and it excludes small wind developments of a domestic or small business scale, typically single turbines of under 50kW capacity, which may be accommodated satisfactorily in most landscapes and in relation to which strategic guidance of this sort is unnecessary." Paragraph 4 indicates that "[SNH] supports the Government's policy to increase the generation of electricity from renewable sources in Scotland." I hope this information is helpful - certainly the experience of previous installations indicates that, once first-hand information is available to the relevant officers and committees, planning permission should be straightforward.
