I think it's important to keep in mind that Renew Economy has its own spin to put on things - just as the Advertiser or the liberal party does. Clearly they want to paint a picture that "everything BUT renewables was at fault". I'd encourage people to read the report itself, which isn't terribly long and is not terribly technical in nature, for an objective view:https://www.aemo.com.au/-/media/Files/E ... y-2017.pdf
A few interesting observations:
- Solar PV peaked at 500MW during the day. Amazing. Of course by the time the event occurred it had dwindled to 150MW. There's a lot of people advocate that "storage is the solution", whereas I'm not so sure. That generation didn't go to waste. It was used. There was nothing to store for when the sun went down.
- Yes there was plenty of gas generators offline or at slightly reduced output due to the heat, but nothing major was absent. It was always going to fall on Pelican Point to pick up the slack.
- A burner at Torrens Island could have picked up the slack, but it has been out of action for a while. This was known.
- AEMO was banking on 200MW of wind to be available, it was producing less than half of that.
- Demand was consistently 100MW higher than expected throughout the evening.
- AEMO did not aske Engie about bringing the second gas generator online until 5:39PM. Engie responded 20 minutes later with the widely reported advice that they need 4 hours to bring the second gas turbine online.
- 2 minutes later the lights started going out.
The key event, for my 2c, was as I've said all along - SA using more power than AEMO (who seemingly run things very tight?!?) expected and they didn't have time to bring thermal back online.
There's a million ways you could avoid this from happening, even as simple as building more fat in to your forecasts. You don't have to turn the grid and its generators on its head.
