Volatility in South Australia on Thursday afternoon 17th November 2022

A quick note this afternoon to record price volatility in South Australia this afternoon – with this NEMwatch snapshot at 16:30:


Three quick points:

1)  Very low wind generation this afternoon;

2)  Lots of solar capability, but with rooftop PV being curtailed through the day because of system security reasons;

3)  No capability of support from the east with the network still severed (through until Sunday evening).

For a more detailed view, here’s an ez2view snapshot at 16:40 highlighting three of the 8 x FCAS commodities in South Australia at the Administered Price Cap following Lower Reg hitting the Cumulative Price Threshold on Monday 14th November:


With many of the thermal generators running in South Australia, we see the level of inertia in the SA grid is higher than it’s been on many occasions in recent years.

  1. I look forward for your review on the day in particular the constraints and synchronous generation dispatched during the day. It was surprising to see Dry Creek peakers and diesel thrown into the mix.

  2. My pv has been constrained to internal demand only until thursday when it was completely cut off to zero.
    This was frustrating as obviously generators had a good day at my and the publics expense.
    No market operating and no feel demonstrated by the powers in charge to allow home pv to cover in home use. This was a planned action to limit pv should have been done with more finesse than it was as the circumstances of too much non scheduled will only increase in frequency (no pun intended!)
