Installation of the V174-9.5 MW™

The V174-9.5 MW™ prototype was successfully installed at Østerild National Test Centre in Denmark in January 2020. Our robust test program has enabled us to thoroughly monitor the reliability and performance output of the V174-9.5 MW™ before serial production commences.

The order pipeline for the V174-9.5 MW™ turbine comprises projects throughout Europe and Asia Pacific, with the first units scheduled for commercial installation off the coast of Germany at both the Baltic Eagle and Arcadis Ost 1 projects in 2022.
