How many smart meters are installed in the United States, and who has them?

In 2022, U.S. electric utilities had about 119 million advanced (smart) metering infrastructure (AMI) installations, equal to about 72% of total electric meters installations. Residential customers accounted for about 88% of total AMI installations, and about 73% of total residential electric meters were AMI meters.

AMI includes meters that measure and record electricity usage at a minimum of hourly intervals and that provide the data to both the utility and the utility customer at least once a day. AMI installations range from basic hourly interval meters to real-time meters with built-in two-way communication that is capable of recording and transmitting instantaneous data.

The U.S. Energy Information Administration (EIA) does not publish data on natural gas meters or water meters.
