2. Self-HealingandAdaptive to correct problems before they become emergencies Interactivewith consumers and markets Optimizedto make best use of resources and equipment Predictiverather than reactive, to prevent emergencies ahead rather than solve after Distributed assets and information across geographical and organizational boundaries Integratedtomerge all critical information More Securefrom threats from all hazards The Power Delivery System of the Future Must Have Advanced Capabilities To achieve benefits identified by stakeholders, the intelligent grid must be:

Information Infrastructure Distribution Receiving Distribution Control Center Gas Substation Station Substation Recip Turbine Engine Distribution Micro- Substation turbine Residential Data Concentrator Commercial Recip Fuel Photo Engine cell voltaics Cogeneration Batteries Flywheel Industrial Residential Commercial 1.Power Infrastructure

4. What is Impeding the Industry? • Lack of interoperability • Limited methods or tools for designing complex systems • Incomplete, overlapping and conflicting standards • Lack of a common “vision” • Regulatory and financial uncertainty • Perceived investment needed

5. An open, standards-based architecture for integrating the data communications networks and intelligent equipment needed to support the Power Delivery System of the Future Provides utilities and others with the tools and processes for designing communications and automation systems Recommends technologies and standards to use The IntelliGrid Architecture Available for Downloadand Public Use: www.epri-intelligrid.com

7. Intelligrid Architecture Business Drivers • Capital Cost Savings • Competitive Procurement of intelligent equipment through Standards and Open Systems • Multi-vendor support and avoidance of single vendor “lock-in” • Extensible and Scalable “Industry-wide” • Life-Cycle Cost Savings • More uniform Standards based systems • Extensible for the Future • More capable, easier to maintain • Immune to single vendor limitations • Security Policy Implementation

8. Consumer Portal

9. What are the Applications?

10. What Could a Portal Look Like? Some Options: Portal in a meter Portal in a set-top box Portal in a stand-alone device or PC Portal in a local energy management system

11. Lessons Learned – from dozens of past attempts • The technology exists. • No breakthroughs are necessary • Make it simple. • Functions should not require customer intervention • Standardize. • Don’t try to “lock in” customers to proprietary systems • Achieve economies of scale and reduce costs • Share the infrastructure. • Use portal-like services from other industries • Build an architecture. • Integrate the portal with the whole energy system • Don’t create “islands of automation” • Don’t strand assets. • Make it easy and inexpensive to upgrade • The best applications may be yet to come • Share the benefits. • Distribute the “societal benefits” to everyone

12. What Could a Portal Look Like? • A consumer portal is an idea, not a particular device! • IntelliGrid is developing a reference design • A standard “virtual appearance” for a portal • A clearly defined set of interfaces • May be incorporated into a variety of devices • May be distributed among several devices • The physical device(s) may vary, but the virtual device must be standardized to ensure • Interoperability between vendors • Reduction in cost due to economies of scale • Some vendors already provide portal-like devices, but they are generally not standardand not interoperable.

13. IntelliGrid Consumer Portal Project • Define requirements so that vendors can build components and systems that are interoperable (open systems). • Information models, object models • Define requirements so that systems will be expandable to meet needs of future service offerings. • Engage stakeholders to create a consensus on these requirements definitions. • Demonstrate the feasibility and performance of systems that meet these requirements. • Move these requirements into the standards process to enhance the applications in the market.
