5. KEMA Propriety Material 5 RFID can improve meter logistics by automating manual processes  Reduce/eliminate meters lost due to errors/incomplete paperwork  Improve supply chain efficiencies  Improve inventory control/material processing  Has other uses as well

6. KEMA Propriety Material 6 In addition to metering, we have seen other utility applications of RFID technology  Tracking high-value equipment: transformers, poles  Refueling management  Emergency/maintenance kit verification  Verify asset installation, inspections and maintenance  Reductions in fleet costs: tire pressure, fuel efficiency impact  Security/safety: Individual access control and tracking  Track specialized tool usage  Operator rounds in generation plants  IT equipment tracking: computers, network equipment  Document management for legal/regulatory departments  HazMat container tracking  Critical asset tamper control  Underground cable ID

7. KEMA Propriety Material 7 WiMax Application – US Utility  Used to Connect Distribution Substations and Field Devices to Control Center Via Backbone Transport – SCADA Data – Communications With Reclosers in Field and Replacement of Dial-up Circuits  Can Be Configured As a Mesh to Allow Backup Paths and Self Healing  Can be used in an AMI architecture

8. KEMA Propriety Material 8 Motes Ad-hoc Mesh Sensing for the utility  A “mote” is a tiny wireless computing platform – Includes radio, computer, antenna, and a sensor – Has a range from 100 to 500 feet – Able to support different types of sensors  Motes are used to build wireless mesh networks – Self configuring and maintaining connectivity – Distributed sensing of environmental data – Senses movement, light, temperature, moisture, sound, impacts, etc.  A utility is testing motes for transformer monitoring  Can use the AMI Architecture

9. KEMA Propriety Material 9 Enterprise Level Substation System Integration (ELSSI)  Utilities want integrated/automated substations to access information for better management – BUT  Wrestling with overwhelming masses of information  Value created from harnessing huge volumes of substation data by:  Converting operational/non-operational data into business intelligence  Organizing this intelligence  Interfacing intelligence with enterprise- level applications  Increasingly linked with AMI the Architecture
