Axpo launches wind measurements at Tannenberg

15.04.25 – Following the start of wind measurements at Flumserberg, Axpo is now also assessing the wind energy potential at Tannenberg, located in the municipalities of Waldkirch and Andwil in the canton of St. Gallen. As a first step, a 125-metre wind measurement mast will be installed on Wednesday, 16 April. The mast will collect precise data on wind conditions, weather patterns and bat activity to enable a thorough feasibility assessment for a potential wind farm.

Tannenberg is Axpo’s second wind energy project in the canton of St. Gallen. Plans foresee the construction of four wind turbines with a total capacity of approximately 22 megawatts. Once operational, the facility could produce around 30 gigawatt hours of electricity annually – enough to supply the average consumption of around 7,000 households.

“Switzerland needs more renewable energy in winter – and wind power can make a valuable contribution,” says Cédric Aubert, Head of Wind Switzerland at Axpo. “By evaluating the Tannenberg site, we are taking another important step towards unlocking the potential of wind energy in Eastern Switzerland.”

The project area at Tannenberg is partially owned by the local civic community of Gaiserwald, which holds land within the municipality of Waldkirch. At a local assembly held at the end of March, 93 per cent of residents present voted clearly in favour of starting the wind measurements and granting the required building rights.

Wind measurement marks the next milestone

On Wednesday, 16 April 2025, Axpo will install a 125-metre wind measurement mast within the municipality of Waldkirch. The mast will collect data over a minimum of twelve months on wind speed, wind direction and general weather conditions. In addition, bat activity will be monitored to ensure that appropriate mitigation measures can be put in place for a potential future wind farm.

Axpo committed to wind energy expansion

Axpo is actively driving the development of wind energy projects throughout Switzerland. In addition to ongoing wind measurements in several regions, the company works closely with local partners and communities to implement sustainable projects. Axpo places strong emphasis on responsible and diligent planning that takes both economic and environmental factors into account.
