Sergey Khudyakov Data Transfer, Inc. Russia Large-scale RF mesh AMR implementation (experience in St.Petersburg)

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 AMR drivers

Why RF mesh? Proven in implementations around the World, significant advantages of RF mesh network over other wired and wireless network solutions Ultimately, technology agnostic – need for reliable data delivery at lowest cost Selected RF mesh from Eka Systems for lowest estimated cost of ownership

Eka Systems Inc.  Leader in wireless mesh AMR solutions for utilities and energy service providers.  Eka’s innovative mesh networking technology, EkaNet TM, is the most advanced and feature-rich networking platform on the market today.  Applications include utility-scale advanced meter- reading systems and energy-management systems.  Organizations using Eka Systems technology include utility companies, original equipment manufacturers (OEMs), and systems integrators. About the provider of the solution

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 re- route Multi-hop: no hop limits, no meter to gateway mapping

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 Connectivity

EkaNet TM architecture EkaNet TM is fully Internet- enabled, providing access to the local wireless network throughout the world. The flexible, scalable architecture is sophisticated enough to handle the rigorous requirements of industrial and commercial environments, as well as ideally suited to very low- cost residential networking applications rver Database Utility CRM Database Electric meters with embedded Eka modules EkaNet TM wireless mesh meter-node network EkaNet TM Network Manager at data center Network Manager Client

Meter multi-brand AMR networks GE kv2c meter DT ECR-3 and ECR-2400 meter Lan&Gyr meter Elster Alpha meter Itron CENTRON meter

Meter multi-brand AMR networks Easy adjustable Compatibility with any meter meter Wireless modem

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 Easy-to-install in any kind of meter Technical highlights

 27,000 single phase meters  293 three-phase meters  25 gateways Pilot project

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 Company facts

Typical building Gateway - 1 Relays - 3 Meters Install time – 2 hours Install team – 3 electricians

Example of self organization Gateways - 1 Relays - 19 Meters - 736

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) Important system features

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 Simplified planning

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 AMI cost of ownership

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 Independence from meter manufactures grants meter multi-brand AMI networks Summary
