Advanced Metering Infrastructure and Customer Systems
Advanced metering infrastructure (AMI) is an integrated system of smart meters, communications networks, and data management systems that enables two-way communication between utilities and customers. Customer systems include in-home displays, home area networks, energy management systems, and other customer-side-of-the-meter equipment that enable smart grid functions in homes, offices, and factories. Time-based rate programs include different types of electricity pricing options for customers that are made possible by AMI and sometimes include customer systems.

Smart Meters Deployed
The chart below shows the number of smart meters funded through the Smart Grid Investment Grant (SGIG) program that are installed and operational. The cumulative estimated number of smart meters, shown as the green line below, is the total number of meters expected to be installed by the completion of the SGIG program and is based on the project plans of the SGIG recipients installing smart meters. Coverage is the percentage of smart meter installations resulting from SGIG funding and is calculated based on the total number of meters in the United States as reported by the U.S. Energy Information Administration (EIA) in the 2009 Electric Power Annual Report, Table 7.1.
The number of meters installed is based on quarterly build metrics reports submitted by SGIG recipients to the Data Hub. To be included in these reports, meters must be installed and operational, meaning that each meter has been physically placed and configured in a manner that will enable it to perform its primary function of recording customer electricity usage and transmitting that information through a communication system to the utility.
SGIG recipients are also required to submit monthly reports to DOE through SIPRIS that include the number of smart meters they have installed. As of October 31, 2013, the number reported in SIPRIS is 15,872,588. This count may be greater than the number reported in this chart because the numbers reported to SIPRIS may include meters that have been installed, but are not yet operational or able to transmit the information that they are collecting to the utility (i.e., able to perform their primary function).

Customer Devices Deployed
This chart shows the number of customer devices that have been installed and made operational through the SGIG program. Customer devices are often used with smart meters to provide information that enables customers and utilities to manage energy usage. Customer devices included in the SGIG program:
- In home displays
- Energy management
- Direct load control devices
- Programmable controllable thermostats
- Smart appliances
