3. Consumers Energy’s Service Territory
1.8 Million Electric Meters
1.6 Million Gas Meters
1 Million gas meters in non Consumers Energy’s service territory

4. AMI – Observations Differences between systems
Proprietary Communication Technology
System logging and auditing
Device registration – device dependant
Collector
Meter
Substation metering
Other (smart grid devices, etc)
Network management interfaces
Outage reporting
Troubleshooting
Monitoring performance
System configuration and upgrades

5. AMI – Observations (Cont.)
AMI communication vendors are not interoperable for maintenance and management
Meter
Collector/Access Point/Mesh Gate/Take out point/Cell Relay/Tower Gateway Base Station/ Base Station
HAN ESP interface managed and implemented different between vendors

6. AMI-Network TF Proposal
Define the devices and well defined points of interoperability within the AMI network for maintenance
Define the benefits of interoperability between AMI network maintenance components to utilities
Sharing backhauls
Gas AMR meters
Water AMR meters
Hybrid AMI systems
Point to Point and mesh and PLC

7. Proposed TF Scope Evaluate existing Maintenance Use Cases
Define New Maintenance Use Cases
Define System Functional Requirements for AMI meters to the AMI head end for maintenance/lifecycle purposes
Identify areas within an AMI network that are viable for maintenance interoperability
Scope is outside of OpenHAN and the Zigbee/Homeplug efforts
Input from the Group???

8. Evaluate Existing Use Cases
SCE use cases
S1 AMI system recovers after power outage, communications or equipment failure
U1 Utility installs, provisions and configures AMI system
U2 Utility manages end-to-end life-cycle of the meter system
U3 Utility upgrades AMI system to address future requirements
Other Utility use cases
AMI Vendor use cases

9. Define New Use Cases
Focus on maintenance life cycle related activities for the meter thru the head end system
Avoid HAN use cases with the exception of the AMI Communication interface with the ESP
IP/3rd party gateways

10. Functional Requirements
Create a SRS (system requirements specification) similar to OpenHAN’s efforts
Derive requirements from the use case review
Focus on the AMI head end to the meter from a network maintenance perspective
Input from the group???
