Communications Infrastructure…Key Enabler Utility Consumer Meter The Grid: Secure Private Network Local Area Network Internet Key Enabler of EE and DR Innovation 2-way Information Exchange Between Energy Services Providers and Specific Energy Consuming Devices

13 © 2006 Electric Power Research Institute, Inc. All rights reserved. Utility Consumer Internet Illustrating the Opportunity Internet used for information exchange only… No control functions and no connection to the grid

14 © 2006 Electric Power Research Institute, Inc. All rights reserved. Internet* Enables Two-way Information Exchange With Specific End-use Devices Future Direction of the Internet Ubiquitous Internet Connectivity Proliferation of Internet Addressable Devices –Could Include Air-conditioners, Thermostats, Major Appliances, Motors, Pumps, Lighting Systems, Etc. *And other standardized wide area communications

15 © 2006 Electric Power Research Institute, Inc. All rights reserved. Innovative Regulations and Rates Electricity prices delivered directly to specific end-use devices Time-of-use Rates Day-ahead hour-by-hour rates Real-time rates Special rates for specific end-use devices

16 © 2006 Electric Power Research Institute, Inc. All rights reserved. Smart End-use Devices Smart, network addressable devices – Air-conditioners, Major Appliances, Motors, Pumps, Lighting Systems, etc. Receive electricity rates through the network Optimize operation to minimize energy costs Measure and communicate power usage through the network to energy service provider

17 © 2006 Electric Power Research Institute, Inc. All rights reserved. Innovative Demand Response Example Air-Conditioning Scenario AC receives day-ahead hour-by-hour electricity prices and day-ahead weather forecast through the internet Consumer sets thermostat at 75° (-5°/+3°) AC “learns” rate of house cool-down/heat-up based on consumer habits, outside temperature, time of year, etc. AC optimizes operation to minimize consumers energy costs AC measures hourly power consumption and communicates it to energy service provider through the internet

18 © 2006 Electric Power Research Institute, Inc. All rights reserved. Innovative Efficiency Example Rates specifically designed to encourage purchase of new, more energy efficient devices Example 5 yr. favorable rates “packaged” with purchase of specific new model of a smarter, more energy efficient air- conditioner, refrigerator, or other major energy consuming device

19 © 2006 Electric Power Research Institute, Inc. All rights reserved. Innovative Electricity Utilization Example Rates specifically designed to encourage new off- peak utilization of electricity Examples 10 yr. favorable off-peak rates packaged with purchase of electric heating system 5 yr. favorable off-peak rates packaged with purchase of new Pluggable Hybrid-Electric Vehicle
