March has had less wind than in previous months but performance
was again very good with only 42 hours total in the month without service supply. The 60
kW turbine was out of service for a total of only 7.5 hours in the month The 100kW turbine
was out of service for 25 hours in the month, 8 hours of which due to a fault on the dump
load fan and 14 hours overnight with a vibration trip. The remaining 3 hours were to
facilitate replacement of the Yaw Pinion.
