While Nysted, the other large farm (72 turbines, 165.6 MW) achieved 39.7%, the small Samsø park (10 turbines, 23 MW) managed 40.2%, and the even smaller Thyborøn-Harboøre park (8 turbines, 18.4 MW) holds the record with 42.76%. (Older off-shore parks are all much lower.) As all of them were finished in 2003, all the above records were achieved in their first and so far only full year, 2004 - which was a rather weak year, so I'd expect new records this year. *Traitor*, n.

The Horns Rev windfarm has been beset by a number of problems and Vestas indeed ended up changing the whole gearboxes for the full wind farm. It cost them in the order of 40m$ (some ot if was paid by ABB, which provided some flawed subsystem).
They've had much better number since the changes, but I'm not sure it's been a full year yet. In the long run, we're all dead. John Maynard Keynes
