8. Smart Energy & Home Automation Urgent demand for Smart Energy + compatibility with mainstreamHome Automation systems enables customer choice Utility AMINetwork Energy ServicesPortal(Electric Meter or Gateway) ProgrammableCommunicatingThermostat (PCT) In-HomeDisplay ZigBeeHAN 8 Load ControlDevice Mobile Phone HVACSystem

9. Utility Requirements for HANs Retail products Competitive market/ No vendor lock-in Low cost Solutions for the Global Market Large pool of people who understand the technology High levels of security Utility AMINetwork EnergyGateway ElectricMeter Tstat HVACSystem ZigBeeHAN SmartAppliances Home AutomationSystem Water Meter Lighting Controls Gas Meter

10. ZigBee Smart Energy Profile Supported Features Include: Basic metering [measurements, historical info, etc] Demand Response (DR) and Load Control Pricing [multiple units & currencies, price tiers, etc.] Text messages Device support for Programmable Communicating Tstats (PCTs), Load Control Devices, Energy Management Systems, In Home Displays (IHDs), etc. Security to allow consumer only, utility only, or shared networks

11. ZSE Security and Authentication Security is critical requirement Smart meter must have secure communications for safe smart grid HAN devices & meters must have strong authentication to assure authorized devices and use Utilizes a Certificate Authority for the device keys Incorporates an Out-of-Band step for an added layer of security Process has been independently audited and approved by Carnegie-Mellon Device Certificate Authority Key Distribution Secure Link

12. Energy Projects Using ZigBee

13. SCE SmartConnect “Southern California Edison will be relying on ZigBee Smart Energy products like these to connect homes to our industry leading Edison SmartConnect program,” said Paul De Martini, vice president at Southern California Edison. “ZigBee Smart Energy products will provide our customers with choice and promote long term sustainability.”

19. North American Deployments As of today number is closer to 40 million electric meters

20. ”ZigBee City”This is how it works ZigBee in Europe Tomas Arnewid – Project Manager

21. Göteborg: ”The ZigBee City” 500 000 Citizens 260 000 meters < 63 A 42 000 meters indoors 180 000 in metering-rooms + Rural area including 15 000 metering points

22. Building the ZigBee NAN Concentrators Meters Repeaters

23. Network Topology

24. Facts and Figures 255 000 Meters (electrical) out of 260 000 installed App. 8000 Concentrators App. 7000…17 repeaters actually used 9 jumps identified, can do 18, have set limit to 10 Infrastructure built to handle 1,1 million meters 3000 GPRS meters >99% within 24 hours, close to 100% 5 days Remote disconnect in use Planning to add district heating, gas and water metering in our infrastructure

25. -Next Steps • Immediate Focus: • Power Quality and Failure alarms – Smart Grid foundation • Multimetering – Gas, District Heating, Water • Advanced Meter Management - implementation of processes • New Services (among others) • Individual metering (heat, water) • Security Alarm • ZigBee locks • Control of street lamps

26. Enhanced Smart Energy Integration of Smart Energy with the IP stack ZigBee+Power Line Carrier Best Practices, FAQ, Ongoing Documentation, marketing Forward-Thinking Developments (PHEVs, V2G, Distributed Generation, etc.) Other Improvements based on continuing feedback and Market needs

27. ZigBee Standards- Looking Forward ZigBee IP PLC Secure Interface Secure Interface ZigBee/PRO Enhancements + ZigBee Green Power ZigBee/ZigBee PRO New Profile ZigBee / PRO Proxy Interface Proxy Interface ZigBee RF4CE Example-Not Final Example-Not Final Today Tomorrow 27

28. Why a ZigBee IP stack? • The United States Congress suggested it in relation to Stimulus Funding access and US utilities are now requiring it as part of their future networks. • What will most likely be in it? • MAC – 15.4 2006 with MAC security • 6lowPAN packet format and fragmentation • ROLL routing • Plus other features essential to effective sensor networks 28

29. Why ZigBee+Power Line Carrier? Simplified installation for new smart energy applications in large apartment or commercial buildings with no other control networks Further expansion of the Home Area Network market by enhancing the ease of use and commercial viability of Smart Energy Advent of PHEVs in 2010 requires energy management system to address technical and business problems related to charging/discharging, billing, and access management. Common system architecture and application profile interface for home energy devices independent of networking technology 29
