I forget where I read it but over 5K of useage comes to mind as a number.
I am pretty sure everyone has a smart meter these days, unless you opted out, but I am not sure you can do that forever either.
But according to this I may be wrong.
In 2021, U.S. electric utilities had about 111 million advanced (smart) metering infrastructure (AMI) installations, equal to about 69% of total electric meters installations.
You can tell by looking at em, but I forget what to look for now.

You have a smart meter if the meter number has nine digits and begins with “2.” (See the “Meter Information” box near the top of your bill.) Check the meter installed on your home. Smart meters are affixed with a Silver Spring Networks sticker at the top of the face of the meter. Analog meters have moving dials.
