What are the rules for a household wind turbine?
Do you dream of producing your own green energy with a household wind turbine? It's a great way to reduce your CO₂ footprint while saving money on your electricity bill. But before embarking on the project, it is crucial to understand the rules and requirements that apply to the installation of household wind turbines in Denmark.
Do you need a permit for a household wind turbine?
Yes. In all cases it requires a permit from the municipality to erect a household wind turbine.
The Danish regulatory framework for wind turbines is relatively complex, and requirements vary depending on the size and location of the turbine.
However, the process for this is quite manageable once you know what is required.
What permissions do you need?
There are always two mandatory permits you must have:
- Land Zone Permit - If you live in a land zone (which most people do if they are considering a wind turbine)
- Building Permit - All household wind turbines require planning permission, regardless of size
The process typically takes 3-6 months from application to completed approval. It sounds like a long time, but most of the time passes with case management.
Municipal differences
It is also important to understand that municipalities may have different local regulations for wind turbines. Some municipalities are more wind turbine friendly than others, and there may be areas where wind turbines are not allowed at all. Many municipalities have developed wind turbine plans or guidelines that specify where wind turbines can be erected and what special requirements apply.
Before you begin planning, we always recommend contacting your municipality to hear about the specific regulations in your area. It can save you a lot of time and unnecessary complications along the way.
Practical tips for complying with rules
Before you start
The first step is always to contact your local municipality and tell them about your plans. Most municipalities are helpful and can guide you on the community plans in your specific area.
At the same time, you should have your property professionally measured to document that all distance requirements can be met. It saves you trouble later in the process.
Finally, check the wind conditions on your plot. A wind turbine sheltered by buildings or trees produces significantly less power and provides poorer economy.
Permission process
When you are ready to apply, the process follows these main steps:
- Advance Dialogue with the municipality
- Land Zone Permit (incl. noise and shadow casting documentation)
- Building Permit (can often be treated at the same time as step 2)
- Network connection - notified to the master data register
- Installation of the windmill
- Commissioning and statutory reporting to the Danish Energy Agency
Plan for service
Remember to think future maintenance into the location. Wind turbines must be serviced annually and service runs must be available on the property.
Solid Energy offers service agreements that typically run over 10 years with the possibility of extension. It ensures optimal operation and maximizes your return on investment.
Environmental and natural considerations
In addition to the construction technical requirements, there are also environmental considerations to be taken into account. In some areas there may be restrictions due to:
- Zone ban - Household wind turbines are not allowed in urban zones. Installation is primarily possible in country zones where there is sufficient space to comply with distance and noise requirements.
- Shadowcast - Indicative maximum of 10 hours of shade annually with neighbors. This can affect the location of the mill and often requires shadow cast calculations.
- Special areas - National parks, nature reserves, and protected coastal or hill areas typically have strict restrictions or bans on wind turbines.
These considerations can affect both the feasibility of installing a wind turbine and the requirements for its design and operation. An early clarification of these conditions is therefore crucial for the success of the project.

FAQ - Frequently Asked Questions
How long does the permit process take?
3-6 months for the whole process. Most of it is waiting time for the municipality, so you don't have to spend a lot of time on it yourself.
What happens if I set up without permission?
You risk injunctions for immediate takedown and substantial fines. Since all household wind turbines require a permit, illegal erection is considered a serious violation.
Can the municipality refuse me to build a wind turbine?
The municipality may refuse if the layout does not comply with applicable regulations or local regulations. But if all technical requirements are met, they cannot refuse permission on the basis of neighbor protest alone.
Can I apply for permission myself?
Yes, but it's complicated with noise calculations, technical drawings and legal requirements. Most use a professional advisor or wind turbine supplier.
How is power settled from my wind turbine?
You first use your own power and the profits are automatically sold at market price. There is a tax-free threshold of 800 GBP. annually for income from the wind turbine.
Does the wind turbine need to be inspected after installation?
Yes. The municipality can require final checks at commissioning. In addition, all certified wind turbines must have annual service inspections by an approved company. This is required by law.
