Advanced Metering Infrastructure (AMI)

Meters, communications and utility data systems viewed as one information infrastructure.

Systems note: terminology, market structures, voltage classes and reliability rules vary by jurisdiction. Use current local standards and utility information for real projects.

Where this fits

Meters, communications and utility data systems viewed as one information infrastructure.

Core system ideas

AMI includes field meters, communications networks and head-end/data-management systems.

Operational value depends on data quality and integration with outage, billing and distribution applications.

Connectivity creates lifecycle and cybersecurity responsibilities.

Interfaces and tradeoffs

Distribution connects the bulk system to millions of individual loads and increasingly to distributed generation and storage. Local voltage, feeder capacity and asset condition matter as much as system-wide energy supply.

What organizations measure

Communications coverage, data completeness, event latency, device health and system availability.
