The legislation provides requirements regarding the distance to dwellings and noise limits. Moreover, wind turbines erected in Denmark or in Danish waters must be authorised under the Energy Agency's technical certification scheme.
Approval of wind turbine plansMunicipalities must approve plans for erecting single as well as groups of wind turbines. An investigation into possible contravention of regulations takes place, for instance with regard to protection of nature and landscape.
The minimum distance to a neighbouring home is four times the turbine's total height. There are no exceptions to the distance requirement.
Read more about the distance requirement on the Danish Nature Agency's website (in Danish).
The construction of a turbine must be registered in advance with the municipality. Part of the necessary documentation is adherence to noise regulations. Noise limits apply to the total noise from all wind turbines in an area. Thus, an application for a new turbine may be refused due to pre-existing noise from other turbines in the area. The municipality cannot make exceptions to the noise regulations.
Following erection and operation of the wind turbine, the municipality may instruct the owner to carry out noise measurements to ensure that the provisions of the Statutory Order on wind turbines are still observed.
Noise limits for wind turbines
Wind turbines must respect noise limits in accordance with the Statutory Order. The limits are:
39 dB (wind speeds of 8 m/s) and 37 dB (wind speeds of 6 m/s)
44 dB (wind speeds of 8 m/s) and 42 dB (wind speeds of 6 m/s)
For both categories of areas the limit for low frequency noise is 20 dB. The limit for low frequency noise applies to the calculated indoor noise level at both 6 and 8 m/s wind speed

To help municipalities plan for wind turbines the Danish Nature Agency has conducted a series of calculations for distances to the nearest dwelling.
The result is a map to help municipalities' further planning and find suitable land for future wind turbines. Data are indicative.

The Danish statutory order on wind turbine noise was revised to include a new regulation of low frequency noise. This applies to wind turbines notified to the Danish authorities after January first, 2012.
