3 Elster EnergyAxis System Overview
03/2003 Elster Electricity – Who We Are Elster Electricity, located in Raleigh, NC, is the former Electricity Metering division of ABB Inc. and Westinghouse Electric Corp. Elster Electricity is a subsidiary of Ruhrgas Industries (RI), headquartered in Essen, Germany, which in turn is now owned by E.ON a large German conglomerate (over $35B in revenues). In the USA, RI owns Elster Electricity, the former ABB Water Metering group, and American Meter Company (gas metering). Together, we are the world’s largest supplier of gas and water meters, and a leading supplier of electricity metering. Elster Proprietary and Confidential (c) 2004

4 History and Experience – We are not new to AMR
Our AMR, Load Management, & Distribution Automation experience began with Westinghouse and extends over 35 years 1960s Pilot-wire meter reading and Telephone AMR 1970s Encoding meter registers EPRI trials of 2-way carrier and 900 MHz radio 1982 EMETCON power line carrier system introduced 1980s Solid state recorders & communications Load Management and Distribution control systems (Carrier, Ripple, VHF & FM/SCA RF) 1990s TranstexT home automation (Telephone & CEBus) 1990s - Telephone, Cellular, CDPD, satellite and RF communications solutions for C&I metering 1999 AMR Server data collection and enterprise meter data repository 2003 EnergyAxis 900 MHz AMR system = Commercialized systems

5 Elster AMR Philosophy Provide two-way options whenever possible
Favor meter data “from the meter” solutions Direct electronic register reads Billing data auditable at meter NO intermediate pulse storage errors or network computations Integrate meters and communications for cost-effective solutions Provide Meter Information solutions, not just “AMR”

7 EnergyAxis AMR System Elements
MAS Data Collection Systems RS-232/ RS-485 Analog Cellular Telephone or Cellular WANs RS-232 with CDMA/1XRTT or GSM/GPRS ALPHA Meters with Communications Commercial, Industrial, Residential EnergyAxis 900 MHz LAN REX Meters with RF Communications Residential, small Commercial A3 ALPHAs with RF Communications Commercial / Industrial Future Water & Gas with RF Communications

8 NEW Elster EnergyAxis AMR System
Entirely meter-based AMR system Residential, commercial, industrial Electric solutions, future Water and Gas Uses proven MHz unlicensed radio for local area networks and public Wide Area Networks New Elster-designed repeating RF “mesh” LAN architecture Elster MAS Data Collection systems on Windows 2000 PC platform can support up to 200,000 meters each

9 Elster EnergyAxis AMR System for Residential
Integrates 900 MHz communications into REX and A3 ALPHA electronic meters 900 MHz repeating RF LAN Solution for single-phase Residential and small Commercial applications Future RF WANs Telephone MAS Comm Server

10 Elster AMR Functionality - Commercial & Industrial
Public Networks (Telco / Cellular) 1-ph REX Meters EnergyAxis 900 MHz LAN REX meters for single-phase Commercial available today Public Networks (Telco / AMPS / Digital Cellular / Paging) Single or 3-phase ALPHAs Polyphase ALPHA meters with multiple WAN AMR options available today 3-ph A3 ALPHAs Polyphase A3 ALPHAs with repeating RF LAN communications now available for energy & demand metering only Small Commercial sites, Strip Malls, Shopping Centers, Large Industrial Sites MAS Comm Server

11 Single-Tier Drive-by AMR Systems
Suitable only to replace monthly meter reads One-way inbound only Limited data collection capability Energy only for residential Energy & demand or limited TOU for C&I (Elster A3 ALPHA with Itron ERT50ESS)

12 Single Tier Fixed AMR Networks
Collectors are pole-mounted Difficult to site Required bucket truck and crew to install or service Costly to wire for power & comms In Star topology, range of sub-networks is limited to one 900 MHz hop ( ’) Meters cannot communicate around obstacles Requires many more collectors to cover a given area Needs more alternate “fill-in” technologies Collector ft Systems function as one-way inbound AMR Modules have limited functionality, basically Energy pulse counts

13 A Mesh Network Assumes Obstacles
Elster employs a ‘controlled’ mesh where the Collector meter sets up the meter/repeater network Algorithms emphasize reliability to each meter and allow paths to change in an organized fashion when needed. Network configuration and changes are transparent to the operator. C Mesh networks were developed for battlefield conditions where units are moving. Every radio repeats every message it hears. This is chaotic and can lead to interference when units are fixed.

14 Elster AMR System – Key Differentiating Feature
New Advanced Elster RF network Proven 900 MHz unlicensed communications Intelligent 2-way communications to all meters Mesh Network RF LAN architecture Any meter can be a repeater Mesh networks controlled by A3 ALPHA Collector Meters Architecture provides up to 7 Repeater Levels (8 ‘hops’ ) Allows communications around obstacles… fewer coverage “holes” Expands Collectors’ coverage area… fewer units = lower costs System Algorithms: Optimize communications reliability to each meter Support Automatic RF registration for “Plug and go” installs Allow Self-healing communications – Units will re-register via alternate paths when local RF conditions change

15 Cost-Effective for Both Targeted or Mass Deployments
High-cost, Hard-to-Access, Dangerous, or High-Turnover Areas Mass Residential and Commercial Areas Apartments Student or Military Housing Industrial Campuses
