  2. What is a Smart Grid? • Supports Energy Efficiency • Modernization of Grid • Demand Response • Supports Renewable Generation • Support Distributed Energy Resources

  3. Energy Efficiency • Large untapped resource - 50% load growth can be met with programs • Time based rates • Customer feedback via Home Area Network • In home displays, Home Energy Management • Billing Options such as pre-payment

  4. Grid Modernization • Existing • Substation protection • Feeder automation • Distribution automation • Volt-VAR optimization • New • Home area networking • Distributed monitoring & control • Distributed energy resources • Goal • Integrate existing grid monitoring & control to new distributed & customer focused resources • Requirements • New generation of distribution management systems • Pervasive & secure communications • Advanced analytics • Dynamic control

  5. Demand Response • Key element is dynamic energy pricing • Allows consumers to see and react to pricing before they use the energy • Studies show consumers are interested if they can save 10% or more • Demand response uses: • Economic dispatch to reduce generation costs • Socioeconomic dispatch where consumers respond for the benefit of society as whole • Reliability dispatch to reduce/eliminate service interruptions • Key Success Factor - Consumers will want something simple and accessible to interact with the grid. Set it and forget it.

  6. Renewable Generation • Major sources • Wind : 2008 US overtook Germany as world’s leading source (25 of 121 total GW) • 1000 MW of Wind in Ks by end of year • Solar: US expected to take world lead this year • Issues • Distributed nature of supply • Intermittency of supply • Forecasting supply (availability, adequacy) • Potential for decreased reliability

  7. Distributed Energy Resources • Micro-generation • Micro-turbines • Fuel cells • Energy storage • Ice energy storage for AC • Rechargeable batteries • Plug in Electric Hybrids (PHEVs) • Vehicle-to-grid = source for on-peak supply & energy storage • Goal of all distributed energy resources is efficiency, demand distribution / peak shaving, environmental impact reduction & other ancillary services

  8. Smart Grid Enablers • Integrated Communications – Robust, integrated, two-way communications • Sensing and Measurement – Enhanced synchronized distribution system measurement and monitoring • Advanced Components – Power system devices that apply the latest in materials, energy storage, and electronics to determine the grid’s behavior • Advanced Control Methods – Methods to monitor essential grid components and enable rapid diagnosis and timely, appropriate, response to any event • Improved Interfaces and Decision Support – Seamless, real-time applications that enable grid operators to make decisions quickly • Applications – Linking consumers to producers and all elements of the energy/resource value chain

  10. Westar Smart Grid Components Smart Meters Customer Engagement Meter Data Management Outage Management System Distribution Automation 10

  11. Smart Grid Benefits Customer Notification of outage and restoration Detailed energy usage information Manage energy usage Supportive of renewable and distributed generation Dynamic time based pricing Personalized customer services, products and programs Westar Operational efficiencies Supports comprehensive energy plans Manage peak load 11

  12. How does Smart Meter support Smart Grid? • Distributed Measurement Nodes • Time synchronous interval data measurement for entire grid • Sense & Measure today, control tomorrow • Outage & restoration notification • Momentary outages, restoration efforts • Voltage monitoring & control • Loss detection – theft and line losses • Power quality monitoring & control • Load flow & monitoring • 2 way common, secure communications system to support distribution automation monitoring & control • Enables demand response solutions • PCT’s, DLC, HAN, IHD with command acknowledgement & verification

  13. Recovery Act Opportunity Smart grid investment program Awards from $500K to $200M Up to 50% DOE match DOE FOA rules pending ?? First filing deadline 45 to 60 days after FOA Two year program Strict reporting requirements Shovel ready projects required 13

  14. Opportunities • IT Development – From Basement to Dryer • Federal and State Policies/Incentives • Meet Changing Customer Expectations • Managing Cultural Changes • Products and Services • Inter-operability and Security • Organization Readiness • Future Technologies
