Land Use Planning for Wind Energy in Aachen – A Milestone for Climate Neutrality

Wind Energy in Aachen: Legal Planning for Climate Neutrality

In the months of May and June 2026, the city of Aachen set decisive course for its future energy supply. Within the framework of land use planning (FNP), a proposal was made to allow the expansion of wind energy within the city limits. The goal is to create the prerequisites for the targeted expansion of wind turbines and energy storage systems – a crucial step on the path to climate neutrality by 2030.

The Land Use Plan AACHEN*2030 – Wind Energy Areas

Amendment No. 2 of the Land Use Plan AACHEN*2030 – Wind Energy Areas – is part of a comprehensive planning effort aimed at strengthening the expansion of renewable energy in the region. The proposed amendment provides for 12 areas in 5 city districts that are to be designated as wind energy zones. These areas cover approximately 324.5 hectares and account for about 2.0% of the city of Aachen.

These areas are so-called “rotor-outside areas,” meaning that the wind turbines themselves may be built outside the designated areas, while the land use plan ensures a privileged assessment under § 35 BauGB. On these areas, a plant potential of about 20 wind turbines (WEA) is realizable, including repowering measures. The estimated capacity per turbine is approximately 4.5 MW, which translates to about 225 gigawatt-hours of wind power per year – almost a fifth of the city of Aachen’s total electricity demand in 2024.

Citizen Participation and Political Debates

The planning process was not only technically but also politically and socially controversial. Public participation had already taken place in the past, but the current amendment has once again sparked intense discussions. For example, the district council Aachen-Richterich recommended to abandon wind energy areas No. 2 and 3, while for area No. 1, a densification of the turbines and the installation of energy storage systems is to be examined.

Citizens raised concerns in their submissions, including noise pollution, shadow flicker, light reflections, species protection, landscape aesthetics, and environmental impacts. The precautionary distance of 400 meters between wind turbines and residential areas was particularly critically discussed. A citizen initiative from Haaren also submitted signatures to support a statement.

The political parties showed varying levels of engagement: The FDP called for the creation of storage options and a financial participation of citizens in wind turbines. The AfD rejected the installation of wind turbines in principle. The SPD and CDU emphasized that climate protection and nature conservation must not be pitted against each other and called for careful planning.

Climate Protection and CO2 Savings – A Positive, but Low Relevance?

According to the official documents, the measure is evaluated as “positive” for climate protection, but the CO2 savings are estimated to be “relatively low” – less than 80 tons per year, which is less than 0.1% of the annual savings target. The increase in CO2 emissions caused by the measure is also considered to be low. There is no known compensation for the resulting emissions.

Despite the low quantitative savings, the measure is considered indispensable from a strategic perspective. The Integrated Climate Protection Concept (IKSK) 2.0 of the city of Aachen sees the expansion of wind energy as a central building block. In addition, the city is part of the EU Mission “100 Climate-Neutral and Smart Cities by 2030,” which further underlines the need for action in the area of renewable energies.

Previous Developments

In April 2026, Aachen decided within the framework of the climate protection concept AACHEN*2030 to expand e-mobility and wind energy in order to be climate neutral by 2030. To this end, around 2,300 charging points for electric vehicles are to be created by 2030 and 12 areas for wind turbines are to be used, which could cover around 22% of the electricity demand.

Outlook: What comes next?

In the period from May to June 2026, the legal and political foundations for the expansion of wind energy in Aachen were laid. The administration will be tasked with initiating an informal participation process to further involve citizens in the design process. At the same time, it is being examined whether densification options and energy storage systems on the planned areas are sensible.

The final implementation of the plan now depends on the approval of the authorities, the involvement of the authorities and further citizen participation. In addition, environmental impacts must be examined in detail and emission protection assessments must be prepared as part of the approval procedures under the Federal Immission Control Act (BImSchG).

The current planning is a milestone in Aachen's climate policy. It shows how the city is advancing the expansion of renewable energies with concrete measures and political decisions – even though the road to climate neutrality is still long.
