8. #ConnWeek Santa Clara, CA May 23-26, 2011 8 Policy and Standards Standards –NIST SGIP process a resounding success Standards efforts accelerated many times over “normal” Action plans march toward completion –Major impacts this year OpenADR and OpenADE – consumer side Plug-Ins / Plug-Fests – Clearing demonstrating the value –Issues – ZigBee SEP 1.x / 2.0

9. #ConnWeek Santa Clara, CA May 23-26, 2011 SEP 2.0 - Technical Issue in ZigBee Alliance Transport layer –Current impasse is rehashing debate from June 2010 where decision was made to proceed with HTTP/TCP –HTTP/TCP Widely deployed (i.e., billions of browsers and devices) Mature (ratified in 1997) Designed for reliable communication links (e.g., Ethernet, DSL/cable, Wi-Fi) Offers end-to-end security from SCE to HAN devices Integrates much more easily with consumer technologies (e.g., browsers, tablets, smart phones) –CoAP/UDP Not deployed Not mature (at least 8-12 months from ratification) Designed for constrained devices (e.g., ZigBee, smart grid T&D sensors) Requires terminating and bridging security (i.e., potential exploits) Would require consumer technologies to adapt to support Some don’t care which transport is used –Engineering analysis indicates both will fit on SCE meters –SCE wants the functionality in SEP 2.0 –Transport is analogous to choosing between PVC or copper pipes –Both transports can run the SEP 2.0 Application Layer –Vision is the SEP 2.0 information model is transport/technology agnostic (Can run on, WiFi, Homeplug and ZigBee) PHY MAC Network Transport Presentation Application 802.15.4 RPL IPv6 HTTP/TCP or CoAP/UDP XML or EXI SEP 2.0 Proposed SEP 2.0 Stacks

10. #ConnWeek Santa Clara, CA May 23-26, 2011 Multiple customer communication channels Multiple Communications Capability complications –Needs to be seamless to operator –System needs to route/takes fastest path to applications –Registration and security coordination is more complicated (peer to peer secure connections) Security issues particularly of trust (trusting consumer devices and public networks Utilities cannot keep pace with fast cycle technology using slow cycle infrastructure Utilities need capabilities to develop secure connections to their customers using public and private networks (the utility industry is not typically staffed for this type of work) It’s unclear how utility role in controlling non-utility owned devices needs to evolve to ensure grid reliability Utilities need to decouple standards development from deployment and design to evolve implementations as standards evolve

11. #ConnWeek Santa Clara, CA May 23-26, 2011 11 Policy and Standards Policy –Consumer right to opt out of metering technology –Question comes to mind – what else can I opt out of? –Consumer education and especially listening needs to become a focus
