In response to Honda & Ecotricity’s letter, IllWind have provided the evidence below which substantiates some of their claims that they have made regarding minimum wind turbine separation:
Extract from Scottish Policy Document (Para 190):
When identifying areas with potential constraints on wind farm development, planning authorities should consider the following:
- the historic environment,
- areas designated for their regional and local landscape or natural heritage value,
- tourism and recreation interests,
- likely impacts on communities, including long term and significant impact on amenity,
- impact on aviation and defence interests, particularly airport and aerodrome operation, flight activity, tactical training areas, aviation and defence radar and seismological recording, and
- impact on broadcasting installations, particularly maintaining transmission links.
A separation distance of up to 2km between areas of search and the edge of cities, towns and villages is recommended to guide developments to the most appropriate sites and to reduce visual impact, but decisions on individual developments should take into account specific local circumstances and geography. Development plans should recognise that the existence of these constraints on wind farm development does not impose a blanket restriction on development, and should be clear on the extent of constraints and the factors that should be satisfactorily addressed to enable development to take place. Planning authorities should not impose additional zones of protection around areas designated for their landscape or natural heritage value.
Anti-wind farm campaigners have welcomed Lincolnshire County Council’s plans to publish a list of criteria developers would need to meet in order to build onshore turbines.
Despite applications for such sites being handles by district planning officers, the county authority say they want to make their views known, so a more uniform approach can be taken to protecting the rural landscape.
And that could see a better deal for residents, with renewable energy companies avoiding potentially contentious areas all together as they know in advance that permission is likely to be rejected.
One of the proposed automatic county council objections would be for any development within the Wolds area of outstanding natural beauty – or for turbines over 100m, within 2km of it.
In addition, the council would object to any large turbine development within 2km of a village, anything which would spoil a 10km view from recognised Ordinance Survey view points or anything which compromises the “visual dominance of Lincoln Cathedral”.
The UK Noise Association recommend a minimum of one mile (or 1.5 km, just under a mile) between giant wind turbines and homes.

German manufacturer Retexo-RISP suggest on their web site that “buildings, particularly housing, should not be nearer than 2 km to the wind-farm“. That was written when turbines were half the size of today’s models
