2. The Power of KEMA From the Generator to the Consumer Serving the Diverse Needs of the Energy Marketplace Strategy, Operations, Technology • Established in 1927 • 1,500 Professionals in 18 Countries • World-Renowned Expertise-Based T&D Engineering, Consulting, and IT Integration Company Independent Advice, Expertise and Evaluation

3. Agenda – Things to watch • AMI Future Vision State • Emerging Technologies: • RFID • WIMAX • Mote (ad-hoc mesh technology) • Enterprise Level Substation Systems Integration

4. KEMA perspectives on AMR and AMI KEMA views the evolution of AMI as an integration of interconnected networks, functioning in concert to unlock further value for utilities, customers, and stakeholders. AMI Future State Vision • Keys to Success • Interoperability of communications protocols and vendor products • Multiple integrated WAN metrology and backhaul options • Fully-featured MDM system and integration with enterprise systems • Robust data authentication, encryption, and privacy (security) features • LAN capacity to accommodate HAN growth C1 Premise Gateway C2 • Lighting • Thermostats • Load Control • DG Systems • Home Gateways C3 Power Line Wireless Wired Commodity Meter(s) Field Collectors/ Aggregators Back Office Infrastructure Wide Area Network Local Area Network Advanced Meter(s) Home Area Network (HAN) Options include: Wireless (WiFi, WiMax), Fiber, Cable, Cellular, Satellite Protocols include: WiFi, WiMAX, Ethernet, Powerline Protocols include: Z-Wave, ZigBee, Bluetooth, HomePlug, LonWorks

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

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. 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. 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. 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
