company overview
Company Overview
  • Sempra Energy Utilities
    • San Diego Gas & Electric
      • 3.3 million consumers
        • 1.4 million electric meters
        • 900,000 natural gas meters
      • 4,100 square miles
    • Southern California Gas Co.
      • 19.5 million consumers
        • 5.5 million meters
      • 20,000 square miles
project overview
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
project integration scope
Project Integration Scope
  • Snapshot of Statistics (2008)
    • 102 Interactions
    • 24 Application Endpoints
    • 2 Major Deployments (“Waves”) (planned, so far)
  • Mass installation starting early 2009
    • Up to 6000 endpoint installations per day at peak
integration approach
Integration Approach
  • Guiding Principles
  • Integration Patterns
    • Data / Process Integration
  • Data Architecture
    • Process (Roles / Deliverables)
    • Model Layers
    • Service Example
guiding principles
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
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

Message Schema – CIM Based
  • Subset of “Sempra Information Model”
  • Schemas generated from UML model
benefits of using cim
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
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
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
