Advanced Metering Infrastructure (AMI) is a term coined to differentiate bidirectional, high
functionality technologies from older, automated meter reading (AMR) technologies.
According to FERC: Advanced metering is a metering system that records customer consumption
[and possibly other parameters] hourly or more frequently and that provides for daily or more
frequent transmittal of measurements over a communication network to a central collection point.
When utilities explore AMI, they realize that it enables key utility, customer and societal
benefits
• Utility Operational Benefits:
• Improved Outage Detection – smart meters automatically send information when power is removed
and restored
• Improved Meter to Billing Processes – moves from a manual to automated process
• Faster Customer Inquiry Response Time – enables operators ready access to customer information
• Fewer Customer Complaints, More Customer Control – provides system operator with near-real
time information
• Customer Service Connection Convenience – can remotely provision service
• Active Tracking of Inactive Meters and Theft – allows verification that no consumption is measured
on inactive locations
•
•
•
•
•
•
•
Customer and Societal Benefits:
Lower Energy Bills – by shifting consumption to off-peak periods and by conservation
Lower Market Price Benefits – reduces the need to purchase energy at higher spot prices
Deferred Generation Construction Costs – energy reduction can help avoid new generation
Smart In-home Systems – to provide energy information and consumption feedback
Distributed Generation Assets – to measure resources that feed or reduce grid requirements
Smart Grid Technologies – provides means to improve the performance and reliability of the grid

AMI and Smart Grid
Smart Grid and AMI
How AMI reinforces the seven principal characteristics of the Modern Grid
1.
Motivation and inclusion of the consumer is enabled by AMI technologies that provide the
fundamental link between the consumer and the grid.
2.
Generation and storage options distributed at consumer locations can be monitored and
controlled through AMI technologies.
3.
Markets are enabled by connecting the consumer to the grid through AMI and permitting
them to actively participate, either as load that is directly responsive to price signals, or as
part of load resources that can be bid into various types of markets,
4.
AMI smart meters equipped with Power Quality (PQ) monitoring capabilities enable more
rapid detection, diagnosis and resolution of PQ problems.
5.
AMI enables a more distributed operating model that reduces the vulnerability of the grid
to terrorist attacks.
6.
AMI provides for self healing by helping outage management systems detect and locate
failures more quickly and accurately. It can also provide a ubiquitous distributed
communications infrastructure having excess capacity that can be used to accelerate the
deployment of advanced distribution operations equipment and applications.
7.
AMI data provides the granularity and timeliness of information needed to greatly improve
asset management and operations.
Smart Grid and AMI
How AMI relates to the 5 key technology areas of the Modern Grid
1.
Integrated Communications: AMI provides the last and by far the most extensive link
between the grid (including the consumer’s load) and the system operator.
2.
Sensing and Measurement: Smart meters extensively measure system conditions
(including PQ) down to the consumer level.
3.
Advanced Control Methods: Consumer-side applications process information and
initiate control actions locally (sometimes based on real time pricing). Distribution
operations centers process AMI information and take control actions at the system
and regional level.
4.
Advanced Grid Components: AMI supports the deployment of distributed energy
resources and can reduce the communication network costs of deploying pole-top
distribution automation components.
5.
Improved Interfaces & Decision Support:: AMI consumer portals, home area
networks, and in-home displays provide the human interface and support consumer
decision-making. Decision support at distribution operations centers is enabled by
the additional information provided by AMI.

Demand Response and Distributed Energy Resources (DR/DER) are key areas of AMI and
Smart Grid intersection
• Time-based tariff programs enabled by AMI can help meet customers need for more
efficiency
– TOU linkage to Thermostat program are an effective means of helping consumers
capture economic benefits
– In-home display units can help customers better understand the connection between
consumption and costs
– Metering will be used for Measurement and Verification.
• Distributed energy resources can be effectively managed, administered and
incorporated into integrated reserve management programs: Metering will provide
the requisite monitoring
• Energy storage can be effectively dispatched to offset peaks; Metering will be used
to capture the net results
• Distributed Generation can be viewed, managed and controlled as required;
Metering will provide net use calculations
Reliability
Automated outage and restoration processing at service points is a key function that
can augment existing outage management processes.
• Meters can provide “Last Gasp” messaging that indicates a power failure or
restoration conditions; Back office applications can leverage this to
supplement other network monitoring functions.
• Linkage between meter physical and electrical addresses can be used for
further circuit failure analsys
• Power restoration notification and the ability to individually “ping” a meter
for status can help ensure full restoration in a given area; This could help
eliminate “nested” outage call backs for field crews.
Distribution Grid Management
Feeder and Distribution Automation can be enabled through the AMI infrastructure and with selected upgraded meter
functionality
• Distribution Grid Management
– Communication/control of distribution switches
– Distribution transformer load management
– Utilization of sensors for advanced functions/analysis (fault detectors,
equipment/conductor temperatures, etc)
– Contingency analysis and overload mitigation
– Distribution system voltage management/control
• Self Healing System/High Speed Communication for control/protection
– High speed communication to support advanced sectionalizing schemes
• Sensors and other IED’s are being included as AMI network peripherals
– Many DA vendors are beginning to support open standards that are being used
for AMI networks
– This helps further justify AMI and DA infrastructure investments
Smart Grid and AMI Alignment
Asset Management
Improved equipment health assessment and associated asset management functions
• Regular data capture from field assets can be used to drive intelligence-based
maintenance programs.
– Linking status reports with other key parameters (such as temperature) can now
provide additional criteria to be used for field operations
– Preventative Maintenance routines can begin to displace more expensive Corrective
Maintenance dispatches
– Inventory management can be optimized based on more accurate models
• Load data can be aggregated to identify key areas of interest
– Actual field data from meters can be used to verify load design forecasts and limits
– Critical conditions can be addressed prior to failure or overstressed states
Summary
AMI Background
Linking AMI, Smart Grid, and SAP
• AMI provides the link between the customer and the grid via:
– Smart Meters and Home Area Networks
