That's 'net load', so the graph doesn't show rooftop or grid solar or wind's contribution.

You can see the difference here for today (choose a previous day if it's near the start of the day in California):

The non-grid PV and wind peak is lowered, and shifted a couple of hours later.

And that graph still doesn't show consumer and behind the meter commercial PV impact. Historically there was a double peak, one of which has been wiped out entirely.

The peak still occurs in the evening around 8-9pm. The chart I linked shows a drop in net demand around midday, due to solar's contribution. But my point is the mismatch between peak electricity demand and solar production, which is the same regardless.

That's all from the grids perspective, they only count their own solar and wind.

Here's an animated diagram that explicitly calls out BTM (behind-the-meter) solar:

Right, and you see where maximum demand is at 8pm (even before any solar was installed)? That peak isn't going down by provisioning more solar. Thanks for the gif, it explains exactly what I'm talking about.
