Morning, afternoon and evening volatility in South Australia on Friday 26th August 2022

I’ve not been working today, but the ongoing SMS alerts have continued to remind me of several bursts of volatility today in South Australia.  Here’s a snapshot from NEMwatch at 17:25:

Quick notes:

1)  Dispatch price above $1,000/MWh at present (but above $10,000/MWh for a sustained period this morning)

2)  Off the back of recent volatility, the Cumulative Price is up above $780,000 in South Australia

3)  Very little wind production in South Australia today (i.e. dropped below 10MW for a long block of time through the afternoon):

(a)  Meaning the fuel mix has been a solid block of red (i.e. gas-fired generation) across the past 24 hours

(b)  With solar production during the day; and

(c)  batteries and peaking diesel-fired units doing what they can

4)  Ongoing limitations of imports from Victoria
