Calandawind exceeds expectations (Calandawind bringt die Leistung) Schweizer Bauer, 20. Dezember 2014
Technical inspection wind turbine V112 at Haldenstein May 16 2013
Technical inspection of the tallest wind turbine in Switzerland was successfully completed in collaboration with
Interwind. The Vestas wind turbine V112 with 3 MW power has a rotor diameter of 112 m. The rotor turns at
19 m height and the over-all height of the plant is 175 m. The expected annual production is 4.5 GWh. This is equal to the electricity demand of ca. 1‘000 households and corresponds to the electricity consumption of Haldenstein.
Calandawind has been accompanied by Interwind from the project idea to the hand-over of the turbine to the owner.

Romande Energy: Planning Permition and Objection Wind Park Sainte-Croix August 2016
In May 2013 the commune of Sainte-Croix has granted the planning permition for the wind park Sainte-Croix. Six turbines are planned. 16 objections have been raised till now. The objections will be discussed in fall 2016.
Wind measurement Hochalp AR October 10, 2013
The 81 m high met mast at Hochalp has been decommissioned October 10, 2014.
For 12 months, Interwind measured wind on behalf of the Canton of Appenzell Ausserroden.

DTBird Experiment continues December 20, 2014
Preliminary results will be available in February 2015
DTBird installed successfully April 10 2014
During the last few days a DTBird system for the protection of birds and bats has been installed successfully. The system observes the direct environment of the turbine using cameras and starts a dissuasion signal as soon as the birds fly to close to the turbine. If the birds do not change the direction of their flight, the wind turbine is turned off. The bat activity is studied through microphones and if any danger of collision occurs, the turbine is turned off.
The following partners are part of the research project:
