In 2020, U.S. electric utilities had about 102.9 million advanced (smart) metering infrastructure (AMI) installations. About 88% of the AMI installations were residential customer installations.
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.
