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 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.

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

ZigBee Supports all of these Principles
