Run of price volatility in SA on Thursday morning 25th August 2022

A short article today to record about some volatility in South Australia this morning, as it’s something we might be referring back to later.

Here’s a snapshot of one of the $4,000/MWh price instances – at the 08:05 dispatch interval – via NEMwatch earlier:


With respect to the annotations on the display:

1)  From 06:55 to 08:20 most (but not all) dispatch intervals were above $1,000/MWh:

(a)  with 07:30 and 07:35 above $10,000/MWh

(b)  and even though prices have dropped below $1,000/MWh, they remain higher than normal (e.g. $560/MWh at 09:40)

2)  There’s not much wind in South Australia this morning … and, at the time captured here, not much solar as well.

3)  Imports are constrained in from Victoria; and

4)  In the Market Notice window below, we see a number of forecast ‘Lack of Reserve’ Market Notices for South Australia … both for today (this morning) but also for this evening and coming days.

That’s all for now…
