ZigBee Enables the “Smart Grid” Wireless Control That Simply Works ZigBee enables utilities to meet their business needs, to support the ongoing development of the “smart grid” and to empower customers ZigBee empowers in-home communication for: • customer communication • data presentation • load control • demand response Sources: Itron website [http://www.itron.com/pages/openway.asp/]; DCSI presentation ZigBeeTM Alliance | Wireless Control That Simply Works Slide 35

SCE’s Vision for Advanced Metering Wireless Control That Simply Works SCE envisions a potential advanced metering system as one that could bring customer usage and meter data into the digital “central nervous system” of its power operations. An advanced metering system could be the information backbone for technologies that measure usage and power quality, and enable dynamic pricing and demand response. The advanced system may enable customer-premise information and automation. SCE’s AMI Program was recognized as the 2005/2006 Best AMR Initiative in a North American Investor-Owned Utility in August 2006 by the Utility Planning Network. The scope of SCE’s metering solution is to replace approximately 5 million electric meters for SCE’s residential, commercial and industrial customers (below 200kW in demand)…While SCE is an electric utility, we anticipate that the preferred solution would provide a communications network that could be leveraged by gas and water utilities in our service territory.
