8 95 Acronyms and Abbreviations .. 97 4 AMI and Customer Systems : Results from the SGIG Program Executive Summary 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. The system provides a number of important functions that were not previously possible or had to be performed manually, such as the ability to automatically and remotely measure electricity use, connect and disconnect service, detect tampering, identify and isolate outages, and monitor voltage.

9 Combined with Customer technologies, such as in-home displays and programmable communicating thermostats, AMI also enables utilities to offer new time-based rate programs and incentives that encourage customers to reduce peak demand and manage energy consumption and costs. This report shares key results and benefits from the 70 SGIG projects implementing AMI and Customer system technologies, and also documents lessons learned on technology installation and implementation strategies. With this report, the Department of Energy (DOE) aims to further accelerate grid modernization by helping decision makers better assess the benefits and costs of AMI and Customer system investments and learn from leading-edge utilities.

10 Major Findings SGIG projects demonstrated that AMI and Customer Systems can achieve substantial grid impacts and benefits for customers and utilities, including: Reduced costs for Metering and billing from fewer truck rolls, labor savings, more accurate and timely billing, fewer Customer disputes, and improvements in operational efficiencies. More Customer control over electricity consumption, costs, and bills from greater use of new Customer tools ( , web portals and smart thermostats) and techniques ( , shifting demand to off-peak periods).
