Construction process |
Road Construction
To facilitate the delivery of the turbines, access roads were constructed to each turbine location. In total 33,9 kilometres of road was constructed.
Foundation construction
Each wind turbine foundation is 19m in diametre and made of concrete and steel and placed below ground level. Each base uses over 60 truck loads of concrete.
Cabling
The cables that bring the power from each wind turbine to the substation are buried underground.
Substation construction
All the cables meet at the substation where the electricity is transmitted onto transmission line.
Wind turbine delivery
The wind turbine towers for Khobab Wind Farm travelled along the N1 from Atlantis near Cape Town, where they were manufactured to the site.
The blades and nacelles came from overseas through a nearby port and were transported by road to the wind farm. Delivery of turbines commenced in November 2016.
Wind turbine parts laid down
On delivery, the turbine parts were laid down alongside the respective foundations ready for lifting by crane.
Wind turbine lifting
It takes two cranes working together to build each turbine.
Completion
Once the turbine was built, it was commissioned and tested and then put into operation.
Operation
Construction is now complete and the project will operate for 20 years.
Energy Fact #7
Many forms
Energy from the wind can be converted into other forms of energy.
