Wind Turbine Design and Layout
3.1 The landscape and visual impacts of a windfarm are strongly influenced by the design and layout of wind turbines. This section focuses upon the different types of wind turbine and their layout or array, while the following section considers how
these principles relate to landscape and visual characteristics.
3.2 Impacts also result from infrastructure serving the development, such as access tracks and borrow pits, anemometers, control building, and substation (where necessary). Design and siting of this ancillary infrastructure are also referred to in
this section.
Turbine form and design
3.3 A wind turbine comprises a tower that supports a nacelle, that is the main shell containing the electric generator and to which the turbine blades attach via a hub.
The nacelle has an anemometer attached so that the direction in which the blades face can be altered to maximise wind capture. Further guidance on wind turbines is available in Planning Advice Note 451.
