Schedule and Operational Data
The wind turbines at Klipheuwel are self dispatching. This means that the turbines will try and turn in the slightest of breeze and start generating automatically once the wind is strong enough. Typical cut in speed or generating speed is around 3 - 4 m/s (15km/h).
Maintenance will be done formally at 6 monthly intervals for two days typically with breakdown maintenance as and when necessary. The latter is however not expected often.
Due to the variability in wind resource a capacity factor of around 20% is expected at Klipheuwel. This means that for every 1MW installed only 200kW will be generated on average every year.
