Advanced Metering Infrastructure (AMI)

Advanced Metering Infrastructure (AMI) is a complete metering system that combines a data measurement unit with a continuously available communication means to provide the capability to sense, measure and collect time-based information (i.e. electricity, gas, water usage), and transmitting such consumer consumption information and system status to an energy provider.

The AMI infrastructure includes:
- Advanced solid state electronic meters, which can be either for electricity, gas and water.
- A communication means, which can be broadband over power line, power line communication, radio network, cellular network, or landline.
- AMI host at the utility site, which receives and manage the data collected from various AMI units and forward the data to the meter data management (MDM).
- Meter data management (MDM), which manages the AMI data and performs analysis to provide meaningful information to the utility.

The AMI infrastructure may also include software, consumer energy displays and etc.

See EPRI's AMI fact sheet here: http://www.ferc.gov/eventcalendar/Files/20070423091846-EPRI%20-%20Advanced%20Metering.pdf


AMI is used to monitor energy consumption information and to send information and system status to an energy provider.
