even if you have home sized batteries (Tesla PowerWall etc), they will not be allowed to discharge to run your house unless you have that fancy switch to disconnect you from the grid

well, fancy switch and batteries it is then

if there is grid damage, its going to have to be turned off to repair it anyway. The batteries would be great for allowing the green transition though.

well i was meaning megapacks powering separate suburbs until the problem is sorted in the neighbourhood in question for exemple, or at the substation. such megapacks could be funded by city councel or something. no need for every house to have their own powerwall. and yea, batteries are cool.
