Clean Capacity Through the Demand Side

“My biggest fear is that we are running out of generation.”- Michael Morris. Chairman and CEO American Electric Power

“Demand Response programs are the most promising and cost effective options for reducing peak demand...”

Advanced Metering Infrastructure (AMI)

■AMI is the use of smart meters, with advanced two-way communication technologies, that enables utilities to:

►Meet their business & operational needs for meter data collection

►Empower ALL their customers to actively and frequently participate in demand response and energy conservation

►Help move toward a smart grid

ZigBee Smart Energyserves the energy industry by enabling

� load control

�demand response

�data presentation of grid status and real time energy cost

�customer communication

�energy management and metering services

with a worldwide open and interoperable standard

ZigBee Powers AMI

ZigBee Powers the HAN

■ZigBee provides an open wireless standard for the HAN [Home Area Network] enabling device networks in the home for load control – e.g. Heating/AC, Security, Lighting, Appliances.


15

HAN Guiding Principles

■ Secure 2-way communications between the AMI Network and the HAN

■ Load control integration (e.g., distributed resource dispatch / control / relaying)

■ Direct access to usage & other meter data (e.g., kWHr, KW, Voltage, etc.)

■ Platform for future customer owned products which leverage meter data and utility/grid information

■ Three types of communications: public price signaling, consumer specific signaling and control signaling

■ Supports communications to other HAN Devices with metering capability (e.g., gas &/or water meter communication, EV sub-metering, PV sub-metering, etc.)

■ AMI Network interface to HAN interface is based on open standards

■ Implementation is appropriate given the high value and relative low cost

■ Potential technology obsolescence is low due to multiple bridging options

Source: UtilityAMI OpenHAN Task Force

ZigBee Supports all of these Principles

“…a HAN communications system in support of demand response applications based on an open standard architecture that complies with nationally recognized non-proprietary standards such as ZigBee…”
