Tobin Richardson Director, Smart Energy ZigBee Alliance
Agenda Discussion of standards in the home ZigBee Alliance & Standards Development What is ZigBee Smart Energy? Market Drivers Expected networks Function Sets Status Update ZigBee Smart Energy Profile 2.0
Customer Benefits of Standards Interoperability of devices Lower cost devices Choice of vendors, solutions, benefits Time to market (benefit for mfgrs also)
Technology Alliances Establish interoperability marks against specific standards for ZigBee, IEEE 802.15.4 Provide testing and certification programs against standards Help drive market adoption through marketing and promotion
ZigBee Alliance Overview Organized as an independent, neutral, nonprofit corporation in 2002 for WSN Standards Development Result: ZigBee enables the Internet of Things and--- it is happening now not tomorrow Open and global-- ~ 400 companies worldwide Activities include: Open Standards for wireless sensor and control Product Certification and compliance programs Branding, market development and user education Only Standard which meets key network requirements for an IoT Self organizing, self configuring, self healing mesh networks, low cost, low energy consumption, scalable to very large sizes, high levels of security, based on open global standards
Ecosystem of Stakeholders Utilities and Retail Energy Providers Government and Regulators Outreach to other standards & requirements bodies such as OpenHAN (within UCAIug) Security Experts internal & external AMI and Meter Vendors Demand Response and Load Control Vendors White Goods Vendors Thermostats Displays Smart Appliances System Integrators Semiconductor Manufacturers
Specification Process Snapshot Open, democratic approach to specification development mirroring IEEE (and other SDO) methods Technical Working Groups manage specification development Organization-based membership and voting attendancebased voting rights Specifications must go through several reviews before ratified by Alliance Board Specifications made publicly available for free download once complete and ratified Smart Energy Public Application Profile open for public comments in process face-to-face meeting this week by SE WG to resolve public comments

Where does ZigBee Fit? Programmable Communicating Thermostats respond to pricing signals and grid disturbances Rooftop Solar provides renewable energy coincident with peak demand Fixed Electricity Storage Batteries stores off-peak power to use during peak periods and backs up Smart Appliances Respond to grid disturbances and shifts consumption during peak demand periods Plug-In Hybrid Vehicles draw energy from its roaming plug-in location. It can store energy for utility use. Source: wsj.com 10

ZigBee Smart Energy Certified Products
Growing Demand for ZigBee Smart Energy ZigBee Smart Energy is the standard of choice for Energy Management and Smart Metering ZigBee Smart Energy is bridging the gap between the power grid today & the Smart Grid of tomorrow Using ZigBee Smart Energy today can improve in building energy efficiency, comfort and convenience all at the same time even without a smartgrid or smart meter Households with digital tools controlling temperature and price preferences saved on average 10% on utility bills ZigBee Smart Energy is an essential element in managing micro/distributed generation, energy storage and electric vehicles
ZigBee Smart Energy Deployments Tens of millions ZigBee electric meters being deployed by utilities Major deployments in California, Texas, Michigan & Virginia An additional 40 million meters (from utility RFPs) in the USA are in various stages of business case development and rate approval with local regulatory bodies State of Victoria in Australia upgrading all its meters British Gas selected Smart Energy for its multi-million meter roll out and will start deployment shortly
AHAM Communications Study This technical assessment finds that these application protocols, and the media capable of delivering them, are the best performing protocols for Smart Grid targeted applications for a consumer audience. October 2010
Next steps for ZigBee Smart Energy Public Application Profile ZSE evolution Developing best practices Over-the-Air Upgrade, multiple ESIs/gateways among available solutions and pathways Additional functionality added (multi-fuel, prepay, PHEVs, etc.) Supporting Market Evolution Continuing to engage key market leaders on defining functionality Engaging key government, regulatory and standards decision-makers in their Smart Grid processes Working closely with OEMs to support market rollout and customer benefit definition Supporting rollout markets (e.g., Texas rollout, 5M+ meters) Supporting additional pilots, trials and market tests around the globe Engaging other key standards efforts (e.g., European Standards Organizations) to facilitate harmonization of standards and market availability of solutions
Next steps for ZigBee Smart Energy Public Application Profile (2) ZigBee Smart Energy Profile 2.0 Development IP stack Smart Energy Profile clearly described in UML Objects derived from IEC CIM (61968) and 61850 Web services Standards Selection (IETF, etc.) SDO feedback Well-defined end-to-end architecture Continuing momentum 2.0 Schedule & Milestones Continued Stack test events into Q1 2011 Stack certification events in Q2 2011 Application protocol testing to proceed in parallel Once stack testing is completed we can move into product testing and certification Later in 2011 expect products to be ready

Curr ent Stat us SEP 2.0 TRD comment resolution complete and now out at letter ballot and public comments public comments due April 26th SEP 2.0 Application Specification (App Spec): Ballot received ~2000 comments that have been resolved Specification is out at letter ballot expecting many more again; spec is more mature now; acceleration effort underway Public comments also requested The positive: we have a draft of a cutting edge application standard that will serve as the foundation of the HAN for time to come and has been widely acclaimed The negative: has not been easy requirements are a moving target with many external factors and contentious items, often caught in middle (CIM vs. 61850, for example) Number of test/interop events have occurred
Proj ect Tim elin e Within ZigBee, specification is not considered to be complete until there are Certified Products Version draft right now is 0.7 specification Once current review is complete Comment resolution Interoperability testing with device manufacturers Development of 0.9 Specification ZigBee Process: Market Requirements Document (MRD) Technical Requirements Document (TRD) 0.7 version of Specification (Interop-Ready) 0.9 version of Specification (Certification-Ready) Final version of Specification (Certified Products)
