You’d want to look over a longer period of time since those figures have big seasonal variations, and we can’t forget that California has a considerably larger economy and population – there are around a hundred countries with populations smaller than the difference between California and Texas - so it would probably be better to make that comparison per-capita or per-gigawatt. Since we’re talking about renewables, greenhouse emissions would also be a good point and it looks like California’s grid is substantially cleaner than Texas’ by that metric according to the EPA, but that’s complicated by California having the option to buy power from outside the state.

In any case, my point was simply that if we’re seeing a system with recurring widespread life-threatening outages described as great, I think it’d need to be almost free or 100% non-polluting to balance that out. The 2021 outage alone was responsible for hundreds of deaths and damages in the hundreds of billions range, so I kinda expect better than “a top competitor to CAISO”.
