Alpha Ventus is a public/private joint demo project, so its performance is (relatively) public. For almost all of the others, only the stakeholders have access to performance data (and those under a strong NDA).

but yes, that's seriously fine performance two years running. The real question is at what cost for O&M. As we speak, AV is installing  and testing lights, so the extensive (one surmises) O&M needed to achieve such CF can be run 24/7.

From DOTI (EWE, E.on und Vattenfall): "Langfristig ist es dabei unser Ziel, den Serviceaufwand für die Anlagen weiter zu reduzieren. Die Erfahrungen dabei kommen nicht zuletzt auch den Folgeprojekten zugute."

CH translate:  Our long term goal is to reduce the O&M costs for the windpark. This experience will benefit the pipeline (future) projects.

The large rotor multi-MW turbines can not effectively operate without highly sophisticated condition monitoring, or O&M skyrockets. It is certainly gratifying to realize that we made some advances which can now be transferred to other industries.
