Certified and approved service companies

Below is a list of all companies that are licensed or certified to carry out service on wind turbines in Denmark as well as companies that are certified to stop, secure, start and test functionality and safety of wind turbines.

For wind turbines with a rotor area of more than 40 m2, it is mandatory to use a service company that is licensed or certified for the type of wind turbine in question.

Other tasks not related to the regular service, such as improvements and repairs can be carried out by specialists that are not licensed or certified service companies. However, these specialists must either be certified to stop, secure, start and test functionality and safety of the wind turbine type in question, or the specialists must carry out the task together with a service company that is certified or licensed for this purpose.

Good to know

For wind turbine types with a rotor area of 40 m² or less, there is no requirement for service to be carried out by a certified or licensed service company. A company can therefore service wind turbines under 40 m2, even if the wind turbine type does not appear on the service company's wind turbine list.
