Interoperability – Why the Utility Cares
AMI – Advanced Metering Infrastructure
 Rapid and evolving technology of the Smart Grid
– Need solutions that could evolve over time without costly rip and
replacement or costly upgrades
 Requires Integration – LOTS of integration
– Onslaught of new applications and technologies
 AMI, MDMS, HAN, DR, ADE, etc.
 Challenges in a complex IT environment
– Many custom systems, legacy system and technologies
– Typically departmentally controlled – within “silos”
 Need ability to govern, manage, and share resources
» Both Intra-Enterprise and Inter-Enterprise
systems/applications


Decoupling of end-point connections and business semantics
Guaranteed delivery
Managed integration
End point compliance to common business semantics and syntax for
information exchange to the public (enterprise)
 End point compliance to service patterns (interaction patterns,
naming and structure patterns, and message exchange patterns)
 Minimal business logic and transformation within the integration
layer
 Leverage IEC TC57 WG14 Interfaces
