Mandating battery storage is nonsense. Making the regulatory system better for it is not, though; it would be good to make it possible for consumer battery systems to do "islanding" properly so they can be true backups.
Or at least not making it illegal. Regulate it all you want, make sure it's safe, but please let's let homeowners install a transfer switch if they're willing to pay for it.
In a longer outage it'd be a massive benefit to have even just a few houses here and there that retain power.
