One World - Planning guidance for micro-wind turbines (6)

The primary planning concerns generated by micro-wind turbines are visual impact, noise and vibrations.

The visual impact of micro-wind turbines depends on the height and siting of the turbine. The height of the mast is dependant on the blade size and the wind regime.

Micro-wind turbines can generate noise levels which may be a nuisance to noise sensitive receptors. However, this is highly dependant on proper installation and maintenance of the turbine.

All roof-mounted systems will transmit some form of energy i.e. vibration, to their support system. Anti-vibration mounts are usually used to mount turbines to the structure.

The potential visual and amenity impacts are likely to be greater when micro-wind turbines are located in the vicinity of each other.

Consequently, siting and location play an effective role in reducing visual and amenity impacts. Ideally turbines are located high up to take advantage of the prevailing winds. Consideration needs to be given so that a turbine does not detract from the architectural integrity of the building.

Areas important for their ecological value should also be avoided due to potential impacts on birds and bats through direct collisions of migrating individuals, as well as a loss of habitat.

Mepa has adopted a precautionary approach towards locating micro-wind turbines in the urban environment. The development of micro-wind turbines should be directed towards industrial areas and suitable locations outside the development zone.

Mepa has published a proposed Planning Guidance for Micro-Wind Turbines. This draft document, which is currently up for public consultation, can be viewed on website www.mepa.org.mt and any comments or suggestions can be sent through e-mail address: microwind@mepa.org.mt by September 11.
