Dear authors,

After the revision of the manuscript the present version is about to be published.
There are two issues that you should address before the next steps are taken:

1) In figure 6 it is clearly shown that the measured mean power curve for wind turbine C above Vrated does show a trend of around 5% over production (~105% of Prated).
Is there a plausible explanation for this? And if so please add a sentence addressing this. (I do suppose this is due to the control system)

2) p 19, line 6: change "wind speed " into "speed shear". (referring to figure 7b)

Thank you for adding the minor improvements suggested by the reviewer Rozenn Wagner. The addition about the definition of the normalized performance is very much welcomed.

The manuscript and the review process will now be checked by one of the chief editors.

Best Regards

Gerard van Bussel

I am happy to see that the manuscript improved considerably during the review process. Congratulations with the publication.
