Why is wind production being curtailed (or “dispatched down”, more strictly speaking)?
It was inevitable that Semi-Scheduled plant would start to experience times when they are dispatched down. It's a big prompt to take next steps up the learning curve.
Analytical Challenge – determining “what might have otherwise been?”
One of the challenges in analysis is to even be conscious of the need to ascertain "what might have otherwise been".
How much wind-powered electricity production has been curtailed in SA since these new constraints were invoked?
An article that sums up some decidedly un-quick calculations we've performed - looking over an 8 week period to 13th September to estimate how much wind power has...
How significant would it be, if Mt Piper were forced to close (at least temporarily)?
A quick look at the scale of the challenge, if Mt Piper were to be forced to close following a court challenge to coal supplies upstream
