Jeffreys Bay Wind Farm consists of 60 wind turbines – model Siemens SWT 2.3 MW. These turbines were selected based on the technology’s quality and compatibility with the local wind regime and its proven track record of over 5170 units installed worldwide as of October 2012.
Jeffreys Bay Wind Farm has sixty Siemens 2.3 Mega Watt machines. See their height and weight statistics below:
By its very nature, wind varies and does not blow consistently all the time. This is why the where the wind turbines are sited is so important; erecting them in an area with prevailing winds ensures that the turbines can generate energy and provide energy to the grid about 90% of the time.
The wind turbine only start operating when wind speed reaches approximately 13km/h.
Wind turbines are sophisticated machines with computer controls.
A typical operating sequence is as follows:
Jeffreys Bay Wind Farm doesn’t fall within the ‘radar buffer distance’ and therefore can’t affect any airport or military radars.
When designing the site layout, our team ensure that turbines are located with ample clearance from the border of the property, main roads and power lines so that, in the highly unlikely event that a tower collapses, it will not traverse the border of the property.
In answer to the concern that wind turbines kill birds, studies show that birds are seldom bothered by wind turbines and in fact, the number of birds killed by wind turbines is negligible compared to the number that die as a result of other human activities.
Studies from the western part of Denmark, show that birds – by day and night – tend to change their flight route some 100 – 200 metres before the turbine and pass above the turbine at a safe distance.
Bird studies formed an integral part of the Environment Impact study done at the Jeffreys Bay Wind Farm site. A 12 month pre-construction study was done, and another 12 month post-construction study will be done to assess impact.
Modern wind turbines are not considered noisy; the mechanical (gearbox/ generator) noise and vibration is almost undetectable with the main sound being the aerodynamic swish of the blades passing the turbine tower.
Animals and livestock ignore wind turbines, and continue to graze as they did before wind turbines were installed.
