May was a relatively calm month during which the 60kW did not
generate for 111 available hours and the 100kWdid not generate for 160 available hours.
The 60 kW turbine was out of service for a total of 45.25hrs. 30 of which was due to a
compressor trip, fortunately during this period there was no wind and virtually no service
was lost. The 100kW turbine was out of service for 8.25 hours in the month.
