  1. CIM for Smart Meter(and Beyond) Sempra / SDG&E Capgemini Xtensible Solutions

  2. Agenda Company / Project Overview Project Scope / Architecture Integration Approach Benefits / Lessons Learned

  3. 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

  4. 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

  5. Project Integration Architecture

  6. 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

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

  8. 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

  9. 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

  10. Process Integration – Typical Pattern SOA Integration Layer e e c c n n a a Application Application i i l l p p ( Source / ( Target / p p A A Consumer ) Provider ) L L M M X Messaging and Orchestration X

  11. Data Architecture - Process

  12. Semantic Model Business Entity Business Entity Business Entity Data Architecture – Model CIS OTHER CIM REFEFENCE MODELS SEMPRA MODEL MESSAGES SCHEMAS DB Schema XML Schema

  13. Process Orchestration Example Service MDMS ESB ESB Operation

  14. Service Definition - Example Service Operation Schema

  15. Message Schema – CIM Based • Subset of “Sempra Information Model” • Schemas generated from UML model

  16. 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”

  17. 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

  18. 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
