Axpo launches wind measurements in Rossrüti

16.04.2026 – On Wednesday, 15 April 2026, Axpo erected a 125-metre wind measurement mast in Rossrüti near Wil (SG), marking an important step in assessing a planned wind farm with three turbines in the Boxloo area. Over a period of at least one year, wind, weather and bat activity data will be collected to support further project development and the assessment of economic viability.
 

In brief:

• Axpo has installed a 125-metre wind measurement mast in the Boxloo wind suitability area in Rossrüti. 

• The mast records wind and weather conditions as well as bat activity.

• Data collected over at least one year will inform further project planning and economic assessment. 

• A planned wind farm with three turbines could generate around 25 million kilowatt-hours of electricity per year (equivalent to approx. 5,000 households).
   

With the installation of the wind measurement mast, Axpo has taken a key step in evaluating a potential wind farm in the Boxloo area of Rossrüti. The 125-metre structure was installed with the support of a helicopter and industrial climbers.

Over the coming months, wind speed and direction will be measured at various heights. In parallel, bat activity will be monitored to assess potential impacts on local fauna at an early stage.

The data collected will form the basis for further project development and the evaluation of economic feasibility.

Strong potential in designated wind area

The cantonal structure plan designates Boxloo as a wind suitability area and provides for the construction of wind energy installations at this site. The Swiss Wind Atlas also confirms the promising wind potential of the location.

Axpo is planning the wind farm together with Technische Betriebe Wil and other partners. The three turbines could generate around 25 million kilowatt-hours of electricity per year, covering the needs of approximately 5,000 households.

Wind Power Particularly Important for Winter

Wind energy plays an important role in Switzerland's future power supply. A large portion of production occurs during the winter months – precisely when electricity demand is particularly high and solar energy produces less. Wind energy thus contributes to supply security, reduction of CO₂ emissions, and regional value creation.
