Pumped storage is useless when there is a drought, or it is full, as the article I linked (and you apparently did not read) explained. Overfilled pumped storage that will be in forced spilled IS one of the reasons for the glut of energy and expected curtailment California will face this spring. Next time please do your homework before posting.
Some of them, sure. But most pumped water storage stations are closed systems and have nothing to do with the drought or excess rain. AND, they could control th espill at peak hours, cutting other peaker usage. It is not like hydro generation cannot be controlled, like in solar r wind. So, I am not seeing the problem here.
If that doesn't work, utilities can always let @FredTMC and other EV owners charge their EVs for a lower price during the few hours around noon.
Note, minimum daily consumption is ~20 GW in California. So, as of yet, there shouldn't be an issue in consuming 8-10 GW of 1-2 hours of peak solar + wind generation.
Even if all you say is true, AND there is really a need to curtail more this spring, it's too late for batteries to impact in any significant manner. This is an unusual year for California rainfall. Most of the time it is getting less rainfall than normal.
