Heating Operation

In heating operation with wind power, the energy generated is used directly to operate electric heating systems, such as heat pumps or electric heaters. The wind turbine supplies the necessary electricity to meet a building's heating needs, reducing the use of fossil fuels and lowering energy costs.

Grid-Connected Operation

In grid-connected operation, the energy generated by the wind turbine is fed into the public power grid while simultaneously covering on-site consumption. Surplus electricity is fed into the grid, for which the operator receives a feed-in tariff. This enables efficient use of wind power and ensures a stable power supply.

Off-Grid Operation

In off-grid operation, the wind turbine is operated completely independently, without any connection to the public power grid. The energy generated is used exclusively on-site, often in combination with a battery storage system to ensure a continuous power supply even during periods of low wind. This mode of operation is especially suitable for remote areas or homes without access to the power grid.

Your wind power solution for home and garden – flexible and efficient.

Our small wind turbines from the ANTARIS series offer you a cost-effective way to generate your own electricity. The models are specifically designed for use in private homes and gardens, and are characterized by high efficiency, reliability, and durability.

Genehmigungen für Kleinwindkraftanlagen in Deutschland

In Germany, the installation of small wind turbines is generally subject to approval, although the exact requirements may vary depending on the federal state and local planning law. A permit is necessary to ensure that the wind turbine does not have a negative impact on the environment, landscape or adjacent buildings. In this context, both building law and nature conservation requirements must be observed.

1. General requirements for approval

The approval requirement for a small wind turbine results from the Building Code (BauGB) and the Renewable Energy Sources Act (EEG). For the installation of a wind turbine, the following steps must usually be considered:

  • Building permit: A building permit is required if the wind turbine is installed as a structural modification on a property. This permit is usually applied for at the responsible building supervisory authority of the respective district or city.

  • Examination under nature conservation law: In many cases, an examination is also carried out with regard to possible impairments of nature and landscape protection. This includes, among other things, bird and bat reports that clarify whether the wind turbine will be erected in a sensitive nature reserve or near breeding grounds.

  • Assessment under immission control law: It is examined whether the operation of the wind turbine has harmful effects on the environment (e.g. noise, shadows).

2. Differences between the federal states

Although there is a uniform legal framework throughout Germany, there are differences in the requirements and processes for approving a small wind turbine, depending on the respective federal states. Some federal states have specific regulations or facilitate certain approval procedures.

In Bavaria and Baden-Württemberg, the roof ridge is considered the so-called zero point when the mast is guided through the roof. Thus, with a roof height of 10m, a 25m high ANTARIS small wind turbine would be procedure-free.

In Baden-Württemberg, small wind turbines must generally be subject to a building permit , especially if the turbine exceeds a height of 15 meters or the output is more than 1 kW. In some cases, smaller installations may also be subject to simplified permitting procedures . In addition, environmental and nature conservation assessments are required if the wind turbine is erected in a nature reserve or near flora-fauna-habitat areas (FFH).

In Bavaria, a small wind turbine up to 15m total height (repeller above) is procedure-free.

In Bavaria and BW, the roof ridge is considered a so-called zero point when the mast is routed through the roof. Thus, with a roof height of 10m, a 25m high ANTARIS small wind turbine would be procedure-free.

In addition, a building permit is required, and nature conservation authorities play a central role in assessing environmental impact. In addition, there are additional regulations in some regions that restrict or complicate the installation of wind turbines, especially in mountainous areas and nature reserves.

In North Rhine-Westphalia, wind turbines with a height of more than 10 meters must also receive a building permit from the responsible building authority. The immission control test is particularly important here in order to check the effects of noise and shadow impact. Nature conservation audits are often necessary in NRW, especially if the wind turbine is to be installed in a nature park or protected area.

In Hesse, a building permit is usually required for small wind turbines. Depending on the region, different requirements must be taken into account with regard to noise measurement and shadow impact . In more rural areas, permitting practices tend to be less stringent, but environmental assessments must also be provided if the wind turbine is installed in a sensitive area.

In Lower Saxony, a small wind turbine up to 15m total height (repeller above) is procedure-free.

The same requirements apply here as in many other federal states, but the approval practice for wind turbines is often less restrictive here, as the state offers great potential for wind power use.

Small wind turbines that are less than 20 meters high can often obtain a simplified building permit . However, if the wind turbine is erected in a nature reserve or near agricultural land, environmental and nature conservation assessments are necessary.

In Saxony, all wind turbines that reach a height of more than 10 meters must apply for a building permit. In addition, an immission control test is required in many cases, especially in urban areas. There are special regulations for the use of wind in nature reserves and in mountainous areas.

Brandenburg has very generous regulations for the use of wind power in many rural regions. A building permit is required here, but there are many areas where additional nature conservation assessments are not required due to lower potential for conflict. However, strict approval processes are required in nature reserves.

In Mecklenburg-Western Pomerania, wind turbines that exceed a certain size must also be approved. Approval is granted by the building supervisory authority, and expert opinions on noise, shadows and nature conservation aspects must be submitted. In areas of special nature conservation value, additional requirements must be observed.

In the big cities such as Berlin and Hamburg, the permit requirements tend to be stricter. Often, both immission control reports and bird protection reports are required. Small wind turbines in urban areas must meet the requirements for sound insulation and visual protection. In urban environments, they are less common, but still possible if the legal requirements are met.

In Schleswig-Holstein, a small wind turbine up to 15m total height (repeller above) is procedure-free.

For further information, please contact us directly and up-to-date.

3. Simplified approval processes for small wind turbines

In some federal states, there are special subsidy programs or simplified approval procedures for smaller wind turbines, especially for their own use. These often include:

  • Facilitated building permit for smaller installations (e.g. less than 10 metres high or below a certain capacity).

  • Less extensive environmental assessments if the wind turbine is installed in less sensitive areas.

  • Promotion of wind power projects as part of state-wide climate protection programs.

4. Conclusion

The approval of a small wind turbine is a complex process that can vary from state to state. It is therefore advisable to obtain comprehensive information from the competent authority or a specialist lawyer before installation. Proper planning and timely obtaining of all necessary permits can minimize legal hurdles and successfully implement the project.

For the specific permit, it is always advisable to contact the local authorities and, if necessary, BRAUN Windturbinen GmbH, as additional requirements may exist depending on the location and type of turbine.

Due to the constantly changing regulations of permits for small wind turbines, we ask you to contact us either (by phone or email) or directly to the responsible local office in your region.
