Solar energy in the region

Statutory resolution on regional planning for renewable energies

The resolution of December 3, 2025 marks the end of a multi-year planning process for renewable energies in the Stuttgart Region. The resolution on the statutes was preceded by two public openings: The first public consultation took place in July 2024, the second in summer 2025.

Transparent and participatory process

As part of the two participation procedures, local authorities, public interest groups and the public had the opportunity to submit comments. A total of almost 300 comments were received. Based on the comments from the first public consultation, the need for changes was identified. These changes were announced in a new public consultation. At the meeting on 03.12.2025, the regional assembly discussed and decided on the overall consideration of all aspects received.

Legal mandate fulfilled

The adopted plan designates 0.7 percent of the regional area as areas that are particularly suitable for PV systems due to their location and previous pollution. This exceeds the statutory area target of at least 0.2 percent.

At the same time, the regional green corridor - a key instrument for nature and open space protection - is opened up for photovoltaic systems, provided that no forest, core areas or core areas of the state-wide biotope network or exposed areas with high or very high landscape quality are affected.

Further procedure

The Verband Region Stuttgart notifies the responsible Ministry for Regional Development and Housing of the partial updates adopted as statutes. Once the plan comes into force, which is expected in April 2026, the new areas and the opening of the regional green corridor for ground-mounted photovoltaic systems will serve as a legally binding regional planning basis for the further planning and approval of photovoltaic systems.
