Project Overview
•
SDG&E installing an AMI system
•
•
•
San Diego and Orange County service territory
• 1.4 million 2-way communicating electric meters
• Upgrade 900,000 gas meters with smart device
Benefits
• Improve operational efficiencies
• Enable customer demand response options
Not a typical utility infrastructure project
• Unlike a power plant, transmission line
• Touches virtually every department
• Leading edge technology
• SOA – Service Oriented Architecture
• AMI – Advanced Metering Infrastructure

Integration Approach
•
•
Guiding Principles
Integration Patterns
•
•
Data / Process Integration
Data Architecture
• Process (Roles / Deliverables)
• Model Layers
• Service Example

Guiding Principles
•
Business Process Alignment
• All of the architectural deliverables will, in some
form, align with the business processes
•
Integration Management
•
•
All integrations will be managed through an
enterprise integration environment
Canonical Data Models
•
Enterprise information model will be built
• Built as-needed, for integration purposes
• Promotes reusable standards

Enterprise Integration Concepts
Integration Framework – Two main paths

Process Integration
Real-time
Individual requests
Web Services through Enterprise Service Bus (ESB)
Guaranteed delivery
Extensible formats (XML)
Transformations in integration layer or in applications
Orchestrated using Process Orchestration Tool

Data Integration
Batch
Periodic
Multiple records
Compact formats

Benefits of using CIM
•
Assists in requirements gathering
• Another reference input for interface analysis
•
Drastically reduces time to create schemas
•
•
•
Practically eliminates discussion about structure
• Best practices and lessons learned “built in”
Building enterprise information model (“SIM”)
• Based on CIM, but incorporates other
standards where applicable
Promotes interoperability through standards
•
Working toward “plug and play”

Future use of CIM
•
•
•
Basis for Enterprise Information Management
• New EIM group to manage information across
multiple projects via enterprise model
Other projects using CIM
•
Smart Grid initiative
Reusability is key
•
•
•
Smart Meter services used in other projects
Other projects services used by Smart Meter
One model across projects simplifies management
• Also allows faster analysis through visibility

Lessons Learned
•
Stay with widely adopted standards
• CIM / HTTP / WS-I (Web Services Interoperability)
•
Establish a governance review process
•
•
•
•
Defined ownership is key to faster decision making
Stakeholders / impacts more easily identified
Keep it simple - Don’t over engineer
Build repeatable process & methodology
•
Less analysis means faster projects
