What gives you that impression? Unless you're looking at the pre-9/11 grid powered by Enron™, rolling blackouts aren't a big deal in California. I think since 2001 there was a single 2 day event limited to certain regions, I don't know anyone personally who lost electricity due to rolling blackouts.

The CA grid has also scaled up battery storage surprisingly quickly. A few years ago it was in the single digit mWh, not really a meaningful fraction of the grid. Now it's measured in gigawatt-hours.

You are right. Not sure where I read it but it was clearly wrong.

Still, I think the grid is very vulnerable with that amount of weather-based energy. If there can be enough batteries to sink all that power generated and have it during evening til morning then that's great.

Perhaps that _can_ work in California, I really don't know what an acceptable level of storage would be. That is, how many days worth of battery power you'd want in case of bad weather conditions.
