California is famous for it's duck curve [0] where peak load & peak solar generation are not correlated. There are many possible solutions, some are technical and some are not. I am currently building one of them [1].

- fulafel 6y agoThat's still a pretty easy situation compared to many places where the storage need is over months and not fractions of days. (Though those places can often do a lot shifting with hydro)
- dehrmann 6y agoCalifornia gets 12% of its power from hydro, but I'm sure they're already shifting that production around to compensate for solar.
- etimberg 6y agoYes, pumped hydro is a very efficient solution for long-term storage. Plus, it is quickly available when needed (on the order of seconds). While the solutions seem simple, putting all the pieces together is the real hard part. It's pretty common to have no data available on the distribution grid and the sensors themselves are expensive and then you need all the related infrastructure.
