1 Large scale RF mesh AMR implementation Vladimir Rizberg Eka Systems, Inc. USA Alexander Merkulov JSC Petersburg Sales Co. Russia NB: Your logo should replace the Spintelligent logo on the right. Should you not wish to place your logo on this slide please delete the Spintelligent logo.

2 Company facts 1,427,224 residential customers 1,982 employees 70 offices payment centers Annual consumption (2005) 2,995 million kwh Annual turnover (2005) 400 million Euro

3 Sales Company AMR drivers Non technical loss elimination Reduce theft Increase payment control Technical loss elimination Transformer loss monitoring Transmission loss monitoring Billing improvements Decrease collection interval Increase total collections Human factor reduction

4 Why RF mesh? Significantly better experience with RF than with PLC in Russian environment Ultimately, technology agnostic need for reliable data delivery at lowest cost Selected RF mesh from Eka Systems for lowest estimated cost of ownership

True RF mesh AMI Self organizing no manual network node provisioning Ad hoc no manual network hierarchy assignment Peer to peer no multiple node types,

5 True RF mesh AMI Self organizing no manual network node provisioning Ad hoc no manual network hierarchy assignment Peer to peer no multiple node types, such as coordinator, router, end device, etc. Self healing & redundant distributed intelligence to reroute Multi hop: no hop limits, no meter to gateway mapping

6 Connectivity RF system operating at 2.4 GHz Reliability of Bluetooth stable, proven, robust License free band in Russia 20 milliwatts of transmit power range of 500m in free space External antenna options add flexibility

Pilot project 27,000 single phase meters 293 three phase meters 25 gateways EkaNet wireless mesh meter node network Eka Wireless Mesh Sensor Network Electric meters with embedded Eka modules Wireless

8 Technical highlights No hard limit of meters per gateway (1400+ in deployment) Multi tier systems security Gateway redundancy each node can go to multiple gateways Option to add battery nodes for multi utility metering

9 Typical building Gateway 1 Relays 3 Meters 166 Install time 2 hours Install team 3 electricians

10 Example of self organization Gateways 1 Relays 19 Meters 736

11 Important system features Bidirectional (demand reset, remote upgrades) Under the glass vandalism Time synchronization (accurate time of use) Redundant data storage at meters and gateways 128 bit encryption Easy to install (no need for highly qualified technicians) Easy to service (few highly qualified engineers)

12 Mesh of multiple buildings Show 3 min movie build into this slide, based on Google Earth 82 MB too long to e mail

13 Simplified planning No limitation on number of hops No network addressing for nodes No hierarchy in network Any node to any gateway No hard limit on nodes to gateway

14 AMI cost of ownership Total cost of ownership often missed in AMI decisions Corporations with only a few thousand employees maintain large IT departments to manage data communications The true cost of installing, managing and maintaining a network of several hundred thousand AMR points is not well understood or fully appreciated by many utilities

15 Summary Selected RF mesh AMI system for 27,000 point pilot with plans to extend to 1,400,000 points Self configuring system leads to rapid and cost effective installation Self organization features of system lead to significant cost savings in operating and maintaining system over useful life Cost of installing, operating and maintaining large AMI networks is significant and not well understood by utilities
