Frequently Asked Questions

How many smart meters are installed in the U.S. and who has them?

In 20111, 493 U.S. electric utilities had 37,290,374 advanced ("smart") metering infrastructure (AMI) installations. About 77% were installed by Investor Owned utilities and about 90% were residential customer installations.

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

EIA does not have data on natural gas or water meters.
