I wonder if a country will just mandate every household to have a Tesla like PowerWall installed within x years. Or some sort of incentives to have it installed. You can then have additional Grid Battery as backup. It is quite hard to store a week long electricity needs without some redundancy.

This won't be possible in all homes, batteries are a security risk so for sure you need safe conditions and space to install similar on how you need to pass inspections for gas. The only way I could see it working is introducing an increasing electricity tarigf. First 50Kw are cheap, next are 25% more expensive, next 50% etc (this are random number I don't stand behind them)
