There are only two value streams for storage. Either rate arbitrage or back up. Rate arbitrage under current TOU rates would take about 100 years to pay back.

In the 15 years before 2019, my house had 2 outages of more than 4 hours, and neither was more than 8 hours which means back up would take about 1000 years to pay back.
I would focus much more on V2H where you can use your EV battery as a battery backup at home.

In a high cost environment I wouldn't do just the battery. I would also add solar. Cost of California electricity isn't going to go down, only up. The overhead costs of the electricity companies is going to stay the same. Facilities and transmission lines are not going to disappear. As more and more folks move to solar the ones left hooked up will pay an even higher rate to support the same infrastructure. California policy makes that clear. They may increase the hook up/minimal charge to solar owners but that will only cause many give up the connection to avoid that fee.
