The Challenge of the Smart Grid
Smart Grid consist of end-to-end, bi-directional flow of energyand communication capabilities from generation toconsumption to:
Improve power reliability and quality Increase resiliency of the grid Increase capacity through optimized generation
efficiency Allow easier use of renewable energy
and distributed generation, including load shifting Reduce consumption on a per user basis Increase consumer awareness and choice

Rooftop Solar provides renewable
energy coincident withpeak demand
ProgrammableCommunicating Thermostats
respond to prici ng signals and grid disturbances
Plug-In Hybrid Vehiclesdraw energy from its roamingplug-in location. It can store
energy for utility use.
Fixed ElectricityStorage Batteriesstores of f-peak power touse during peak periods
and backs up
Smart AppliancesRespond to grid disturbances
and shifts consumptionduring peak demand periods

Smart Energy Use Cases
User gets instant read of consumption data User request meter read via a In-Home Display, Set Top Box
or PC
Request is sent to the meter and responds with informationrequested
User turns on device and sees change in meter data
Results in association of cost of operation per device

User Programs devices to automatically
respond toutility price signals or allows utility direct access
Price signal is sent from utility over their network to the meter
Meter sends the message out over the ZigBee network Devices receive the message and automatically react
Dishwasher schedules start to correspond with best rates Pool pumps schedule filter cycle for best rates
Comfort points (heating, etc) change set point to pre-heat/coolbefore event and reduce usage during high rates

Growing Demand for ZigBeeSmart Energy
ZigBee Smart Energy is bridging the gap between thepower grid today and the Smart Grid of tomorrow
Households with digital tools controlling temperature andprice preferences saved on average 10% on utility bills
Market is starting with large scale rollouts Technology is available today, field trials as well as large
scale deployment is happening now
40+ million ZigBee electric meters being deployedby over 11 utility companies
Major deployments in California, Texas, Michigan and Virginia
Total smart energy meter market in North America of 80 million beyond 2011 (from utility RFPs)
