They have to. Feeding your own home needs some setup but is fine. But electricity companies require you to disconnect generating capacity from the grid when the grid is down to make it easier to effect repairs.
But that's more a policy decision than a technical restriction. We could change it so power can flow on both sides of a fault instead of only the "upstream" grid side.

- PaulDavisThe1st 2y agothat would mean either: a) government mandates that turn over existing grid infrastructure to such a project, because the existing grid infrastructure is almost all privately owned OR b) building new infrastructure to create an isolatable local grid Neither of these seem particularly likely to me.
