When I make my own house, I want to tie a grid of 110V marine batteries into it, with a 3-way shutoff switch. And solar panels. So if the grid ever shuts down, the house can still run on power I generate. And during maintence of the grid, the lights stay on, the fridge keeps running, and I can pretend it never happened. If I overgenerate, I keep a store of it for emergencies, and any past that I sell.
And the ultimate benefit is that if I ever don't like what the power company is doing, I can disconnect and run on my own power.
