1. Introduction to AMI
What is Smart Metering?
• Many different definitions
• Siemens says that Smart Meters “enable” the last mile
– Intelligent monitoring of consumption
– Bi-directional data transmission
– Increased security of supply and higher efficiency
– Variable tariffs dependent on overall consumption and
grid load

3. Introduction to AMI
What Smart Metering Offers
• Provides detailed information on what is being consumed/delivered on a
quasi-real-time basis
– Supports in-home displays
• Provides the data for consumers and utilities to make smart energy
choices
• Improves utility operations by (for example):
– Identifying where energy is being consumed
– Helps localize outages
– Highlights areas with possible energy theft
• Helps customers deliver energy to grid
• Eliminates the need to change meters when services or features are
modified (such as time-of-use)
• Provides a pathway to the Smart Grid

4. Introduction to AMI
Smart Metering Applications
• Monthly meter reading – total consumption
• Off-cycle meter reading – total consumption
• Monthly kW demand read
• Static time of use (e.g., peak, off-peak,
shoulder)
• Real-time pricing (passive load control)
• Curtailment or interruptible service
• Power quality monitoring
• Outage detection

10. Introduction to AMI
Advanced Metering Infrastructure (AMI) is a comprehensive, integrated
collection of devices, networks, computer systems, protocols and organizational
processes dedicated to bi-directionally distributing highly accurate information
about customer electricity and / or gas usage throughout the utility and back to
the customers themselves.
Key AMI Capabilities:
• Record customer consumption and meter event information hourly
or more frequently
• Remote disconnection and reconnection
• Outage detection
• Quality of supply monitoring
• Demand limiting
• Communication interface to in-house displays, direct load control
equipment etc.

14. Introduction to AMI
AMI System or AMS
(Advanced Metering System) collects data from the meters and communicates
the commands from the MDUS to the meters. There can be several AMI systems
(1---n) in an AMI scenario, each one catering for a set of meters.
MDM / MDUS (Meter Data Management / Meter Data Unification & Synchronization
system) is the central system which communicates with the AMS and the Back
Office components. It stores all the Meter data collected from different AMS and
processes it as required by the Back-office applications. It also triggers commands
and events as required by the business to the meters through AMS.
SAP AMI 1.0 = IS-U 6.0 EhP4
SAP also developed a broad number of AMI enterprise services for
communication with MDUS systems

Key Enhancements were made in the following areas:
• Device Management
• Meter Reading
• Customer Service
SAP also developed a broad number of AMI enterprise
services for communication with MDUS systems
