Within the framework of the KonTest project, which is funded by the Federal Economics Ministry, a test site for wind turbines in complex-mountainous terrain is designed. The institutes involved in the project and the WindForS office have now finalized the announcement for the proposed flagship project. The announcement text offers detailed information for interested municipalities and states the criteria for the test site location, the search for a suitable location and the equipment to be deployed. The announcement has been transmitted to more than 3.500 municipalities, cities and regional associations in Baden-Württemberg and Bavaria. Local authorities are asked to communicate potential sites to the WindForS office within the next two-and-a-half months. These will then be evaluated as the next step in the project.
