I live in a rural part of New England with an electricity company that everyone dislikes because it's super expensive and sometimes things go bad. Since 2010 we've had the following major outages:

* October 2011 Snow Storm - Lost power for 4 days, didn't end up being that cold

* October 2019 Thunderstorms - Lost power for 3 days, thankfully generator kept the house going

* August 2020 Tropical Storm Isaias - Caused widespread grid damage, but only lost power for 18 hours. Internet was out for 36 hours.

* August 2021 Hurricane Henri - Widespread grid damage, lost power for about 6 hours. By this point I had powerwalls. I didn't even turn down the air conditioner.

That's it - every other outage has been a few hours. And that's living in a rural area that is heavily wooded with most of the power lines above ground and often long runs close to trees. If I lived in a suburb or city those times would be even less.

The grid in the United States, despite some widespread and documented regional failures (2021 Texas, 2003 NE Blackout), is remarkably resilient.
