California doesn't have rolling blackouts because they created an entire energy market expressly devoted to feeding carbon intensive power into california to cover the many, many, many required MWh that californian solar can't address. This isn't a matter of opinion, you can look at the CAISO power flow statistics online.
As of this moment less than 20% of California's load is satisfied by renewables, per the CAISO website. What facts, exactly, are you trying to point out?
I just looked, and it said 86.4%. And when you look closer it's actually > 100%. Batteries are at -4.5MW (aka they're charging), and non-renewables are contributing only a couple of MW.
