I have looked for costing for wind generated electricity. The only info I found was for Balloo woods:
A cost varies considerably from the number of operational years 12 years warranted figure used is guestimate
This is an oldish small turbine.
Are more modern windfarms more financially efficient?
Any figures out there??
Balancing costs and short term reserves are from uk parliament
conventional backup national grid

I have toured the Hepburn Community Wind Park couple of hours from where I live.
It is run by a community based company (co-op) and consists of a couple of 2.05MW turbines; that site came in around AU$12.1M; I picked it because I have actually been there and seen how simple it is - a couple of turbines, a couple of grid interface devices in shipping containers, gravel access road, cows.
So to scale up Balloo Wood :
top two line items 1324233 pounds = AU$2331179;
4.1MW/0.8MW = 5.125
5.125*AU$2331179=AU$11947292 (so about the same $/W).
Considering the turbines came from Germany, that's a pretty reasonable comparison in terms of installation cost. The turbines themselves are about 10 meters taller than Balloo and operated at 31% capacity last year.
Here's a linky that might fill in more blanks for you https://www.hepburnwind.com.au/journal/half-year-wind-generation/

That website also has a terrific chart of the generation from every state in Australia, by type of power source - updated every few minutes!

It is also interesting to note the way the "bands" overlap - that even at their most expensive end, many of the new technologies are already very competitive with coal (which given your first link to the SA gov site, is pretty much problem # 1 in Australia).
