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


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)

SEP 2.0

Proposed SEP 2.0 Stacks


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


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


Show Highlights on Smart Grid

• Boot Camps - Monday– Introduction to Utility Infrastructure and SG Apps– Introduction to NIST SGIP

• Consumer Symposium - Monday• Benefits - Tuesday• Investments - Wednesday• Implementing SG Standards Now - Thursday• Demand Response – All week
