Not just houses, the power requirements in eg regional switch buildings are serious too, not something a battery will sustain for too long.
Here in the UK, our exchange buildings have emergency battery and diesel generator backups so if power does go out for an extended period, then at least the head ends and exchange equipment will still function.
Even a relatively small building will have a backup generator with a 1000 litre fuel tank.
