In my jurisdiction a battery development is just about the only kind of development that can tell the evil rule and restriction people masquerading as do-gooders to GFY (though of course it still gets kicked in the dick at the state level since we've got a lot of rules others don't).

Grid capacity both locally and at the transmission level is still the biggest factor when it comes to site viability though. You can't back feed a municipal water system by connecting a fire hose to a random house's hose spigot.

Regardless, battery sites are becoming a big thing in long term RE investing because being able to have this site plan developed under favorable rules while all the other rules only ever get worse makes these sites potentially hugely valuable when the batteries are gone in decades.
