Saw this post referenced at a energyathass post, March 13, 2023, and wanted to say thanks for putting the graphs together!
It must have been a wild afternoon in Folsom at CAISO's control center on the 6th of September dealing with the intensity of the heat wave and the challenges of ensuring the dispatchable generation sources came on line in response to the drop off of PV in the late afternoon- the right side of the Duck Curve. Demand response programs were highlighted here-

...."Reliability demand response (RDRR) was also manually dispatched by the ISO on September 5-7 when the ISO declared an Emergency Energy Alert (EEA) 2. Historically high loads led the ISO to declare an EEA3 on September 6."
I noticed that the daily curtailment report indicated almost no curtailment on the 6th-

Rolling black out were not needed to keep the grid up on the September 6th unlike the 2020 blackouts. PG&E's reliability report- https://www.pge.com/content/dam/pge/docs/about/pge-systems/CPUC-2022-Annual-Electric-Reliability-Report.pdf - noted that "There were four weather-related major events totaling 5 weather-related Major Events" . As you might expect September 6th was a Major event day. ...."the year's largest outage event that impacted a total of 512,900 customers in the service territory".
My father-in-law lost power after the Mosquito fire started on the 6th.
