One possibility is to change your utility pricing schedule from a Peak 4:00pm start to a 6:00pm start and see if that starts charging again.

On the CA ISO site, we are about at Peak Demand for the day. But Net Demand (minus renewables) is still going up. If they are starting rolling blackouts now, where is that additional Net Demand power coming from? And, if there is additional Net Demand power available why isn't it being applied now?

I am using self-power mode, don't have rates set. And, looking back things worked fine with the first VPP event and maybe two more.

They haven't started rolling blackouts yet. The outages are probably weather-related but not intentional. They haven't posted an EEA 3 notice yet, which I believe would preceed actual rolling outages.
They're still below the Resource Adequacy Capactity, which I think is the pre-purchased amount. When they go over that, they're going to have to buy in the real-time market. There are still a few GW of unloaded capacity left.
Interesting to me is that the previous record was set SIXTEEN years ago. With all the growth and electrification, I would have expected consumption to have increased much more. Also, if EVs were actually allowed to discharge to the grid to support afternoon demand, things would be much different. Example: 1 million EVs at 50 KWh = 50 GWh, spread over 5 hours, that’s about 20% of the 51 GW peak mentioned in the article. So, imagine 20M EVs, all charging on free excess solar from 10-2, then discharging to support the grid, while receiving $0.50/KWh compensation. Won’t happen, but that’s what they’re scared of.from CA ISO
Californians seek relief as heat wave grips state for eighth day
SACRAMENTO, Calif. (Reuters) -A man in a heat-stricken suburb of Los Angeles and a woman with two young kids in Pomona were among the Californians desperately seeking cool shelter as extreme temperatures baked the state on Wednesday for an eighth straight day. Temperatures were expected to top...www.yahoo.com
I just looked at the Supply graphs from yesterday. The most significant increase is NG. Some increase in imports, but imports were higher in the am then dipped, now going back up, but has not surpassed the morning import peak. Some increase in large hydro.
I think rolling blackouts are now on

same here (state wide i assume?).... us lil piggies that made our house of bricks
are prob feelin better 
I heard on the news yesterday that a number of outages were due to transformers blow up from the high heat. Did notice on the caIOS that there was a Transmission Emergency for northern Calif (PG&E).
Still got mine set to 70, But, my minisplits are using so much that my batteries did not even get above 65%. They will be drained to 10% tonight. It is so hot outside, the house now is at 75 upstairs, still 68 downstairs.
This is the real deal.Still think there’s a real possibility we could be spending a very uncomfortable no-AC night tonight. Lights, refrig/freezer working but not much else depending on reserve setting and number of PWs available.same here (state wide i assume?).... us lil piggies that made our house of bricks
It’s these multiple days/nights of high temps that kill the batteries ability to recharge from the sun (which we have plenty of cloudless days now) when you need to use the AC. Our AC system is old so when we replace next year we should be in a better position.

Wonder how many circuits they shut off at a time. Looks like a pretty good drop in demand. Just shut off the data centers that would lower demand quite a bit, they all can run on generators for a little.
I am in southern california, and got alerts on my phone from SCE about "reducing energy use to prevent blackouts" (paraphrasing). I think this is likely the "stage 2" alerts that @cwied mentioned.
