Driving to Canberra if you come from the north you may pass the Capital Wind Farm. This is the largest wind farm in NSW and has been in operation since late 2009.
It cost about $300 million.
The turbines are absolutely massive with the hub, or pivot point being 80 metres high and the diameter of the blades being 88 metres.
Together, I think, they generate 140.7 Megawatts. Impressive!
