April has had fewer generating winds than in previous months with
more periods of calm but has again been a relatively good month with a total of 68 hours
in the month where there was no service supply. Utilisation of the wind energy produced
was again high mainly due to continuing poor weather conditions for the time of year. The
60kW turbine was out of service for 21.3 hrs. in the month mainly due to low air. The
100kW turbine was out of service for 4.5 hrs. in the month.
