  1. Intelligently Connecting Plug-In Vehicles & the Grid June 2009

  2. Discussion Guide Objective: Understand mutual business objectives surrounding smart charging solutions for electric vehicles. Plan: • Introductions • Review of Current PHEV/EV Plans • GridPoint - Plug-In Vehicles & the Grid • GridPoint – Smart Charging Demonstration • Open Discussion / Next Steps

  3. Smart Grid At A Glance An intelligent network of distributed resources (at the point of consumption) that controls load, stores energy and produces power.

  4. GridPointPlatformTM Web Modules GridPoint Control Console (utility) GridPoint Customer Portal (consumer) Web Interfaces Dynamic Web Engine GridPoint Web Services 3rd Party Wireless Device SDKs EV Management Load Management Storage Optimization Renewables Integration Modular Energy Solutions Energy Efficiency Integrated Services Architecture Metadata Scheduling Provisioning Business Intelligence Security API set Optimization Algorithms Data & User Scalability Intelligent Energy Server Optimization Engine Communications Gateway Open Communications HAN/WAN/Meter Data Integration MDMS SCADA LMP HAN Load Curves Weather External Sources Internal Utility Systems

  5. The Electric Vehicle Management Solution • Proven smart charging experience: • Two-years of real-world smart charging experience • Hundreds of plug-in vehicles currently grid-aware via GridPoint technology • Integrating with Level 1-3 charging infrastructure • Idaho National Laboratory’s (DOE) solution for EV / PHEV data capture • Leading utility customers • Xcel Energy • Seattle City Light • Progress Energy • Duke Energy • ConEd • BC Hydro • PG&E • Austin Energy • ComEd

  6. Electric Transportation Arriving Soon Over 70% of auto makers* are introducing plug-in vehicles *by market share

  7. Establishing a Smart Grid Infrastructure for EVs • Smart Charging: • Manages the one-way flow of energy • Allows drivers to set parameters • Balances grid & driver needs via sophisticated software • Enables adaptive management: • Delay/slow during peak demand • Increase with availability of renewable energy • Plug-In Vehicles • Connecting to the grid in 2010 • Many rollouts call for 240V/L2 wall mounted garage chargers • Adoption likely clustered in neighborhoods • Grid Distribution System • Charging management technologyis required* • Capacity exists for wide EV adoption* • A few EVs, clustered & charging at peak, could impact reliability *National Renewable Energy Laboratory, Pacific Northwest National Laboratory, Electric Power Research Institute

  8. Creating a Reinforcing Cycle of Benefits • UTILITIES: • Delays infrastructure investments • Enhances reliability • Increases renewable integration • Delivers control of a valuable asset – load, storage & generation • VEHICLE OWNERS: • Reduces total cost of EV ownership • Enhances ability to drive “green” Smart Charging • Auto Manufacturers: • Drives sales • Creates a supportive EV ecosystem

  9. Controlling the Power Flow to Vehicles

  10. EnhancedPower Flow Management

  11. One Example of Value—Smart Charging Used to Increase Renewable Integration

  12. Smart Charging Management Opportunities Load ShiftingTime based management shifts charging behavior intonon-peak periods Demand valleys can be filled by scheduling charging around a central time Load Shaping Following an signal or schedule, charging load can be dynamically shaped according to grid needs Renewable Integration Based on a live wind or solar signal, charging can be synchronized with the availability of renewable energy Spinning Reserves The flow of energy can be rapidly slowed or stopped, creating capacity in response to an unexpected power disruption Economic Dispatch Following a real-time price signal allows energy economics to determine charging behavior Load Shaping Economic Dispatch

  13. State of the Art Performance Data Logging Used by Idaho National Laboratory, the same client-server solution that enables smart charging delivers robust performance capture • Advanced AnalysisSupports complex performance evaluation, including MPG, fuel & energy consumption, charging data, etc. • Improved Performance Data • Data is automatically logged & securely uploaded, increasing reliability & enabling real-time evaluation • Increased Flexibility • Multiple methods of intra-vehicle & client/server communication are supported • Remote software updates • Staff involvement in data collection & administration is minimized with remote support & configuration • Enduring Investment • A second software license is all that's required to explore smart charging, no additional hardware is necessary

  14. Smart Charging Demonstration

  15. Preparing for Plug-Ins: What You Can Do Smart charging demonstrations are opportunities to: • Assess the importance of controlling vehicle load at the distribution level • Explore various charging scenarios, including load shaping & peak shaving • Investigate synchronizing charging with wind or solar power • Gain experience enlisting participation in smart charging programs • Determine system requirements surrounding service area “roaming” • Establish the benefits of electric vehicles, confirming efficiency, decreased fuel costs, reductions in green-house gas emissions, etc. How are you preparing for plug-ins?
