The V164 was tested across 6-7 October at a site in northern Denmark. MHI-Vestas said wind speeds averaged approximately 11m/s in the 24-hour period. The data was measured by Denmark's Technical University, which owns the test centre.
A prototype of the turbine has been installed at the Danish test centre in Osterild since January and has been operating with over 90% availability since.
MHI-Vestas CEO Jens Tommerup said: "Our main focus now is continuing to document the performance of the turbine to measure the power curve and the power quality in order to receive type certification."
It is the largest turbine currently in existence and has already been contracted for use at Dong Energy's 258MW Burbo Bank extension in the Irish Sea.
A second prototype is set to be installed to continue testing before MHI-Vestas gains a type certificate next year. Series production is slated to begin next year.
