Böttingen-Buch wind farm

The three wind turbines of the German manufacturer ENERCON, type E-175 EP5, are expected to produce around 45 million kWh of clean electricity per year. This is theoretically enough to supply around 25.700 people with renewable energy.

The wind turbines are located on predominantly agricultural land, including fields and meadows. Extensive wind measurements and studies relating to nature conservation and species protection form the basis for the planning of the wind farm.

The repowering project ends to the southeast. Böttingen-Hühnerbühl wind farm, also a project of Schöller SI. The parallel development of both projects allows for synergies to be exploited and parts of the building infrastructure to be shared. This enables efficient and resource-saving implementation.

The distribution system operator Netze BW has allocated a grid connection point on the existing 110 kV overhead line Laichingen – Schmiechen, approximately 9 km as the crow flies northeast of the planned wind farm, where the electricity will be fed into the public distribution grid.

For this purpose, Schöller SI built its own substation in the Sontheim district with a transformer size of 80/100 MVA, which has been in operation since July 2025 and also serves as a grid connection point for the Magolsheim wind farm is used.

To leverage synergy effects, part of the external cable route of the Böttingen-Buch wind farm has already been laid with that of the Magolsheim wind farm. This has the advantage of ensuring optimal use of the available construction space, taking into account existing road and path infrastructure, third-party lines, and nature conservation concerns such as adjacent protected areas and existing vegetation.
