At the end of the day the issue is cause by Hazelwood shutting down.
SAs problem is still the lack of generation. I'm not suggesting that Northern or Playford B were the answer as I and fully aware of the issues with the Leigh Creek coal source, however another generation source to SAs Market would make a big difference.
There are a couple of pumped hydro projects that could inject another 250 - 400 MW to our grid being looked at.
Also hats off to Jay and his guys, whilst I do feel he has let us down in the long term with energy, his government engines project provided the needed stabily and generation to the grid.
What we need is to get these engines on to gas and get them part of the market. If that means the SA government become an energy player again, then so be it.
That really depends on what time of the day yesterday you single out - was over 60% renewables in some parts. At 3.30PM SA renewables output was 65.7% and 8GWH was being exported to VIC.
Realistically, it wasn't renewables at fault - coal provided nothing when needed:
- loy yang A unit 2 530MW
- loy yang A unit 3 560MW
- yallourn unit 3 380MW
- yallourn unit 4 380MW
All out of service yesterday. And if you include liddell unit 2 @ 500 MW, that's 2350MW out of service in NSW and VIC. NSW and VIC were bailed out by SA.
Mega batteries and a pumped hydro plant can cover the gaps that existed on Friday.
