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

Posted by Paul McArdle Friday, August 26 2022 Topic: Winter 2022 in the NEM

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
