3 3 Overview Australian Electricity Market  Australian government pursuing energy market reform improve supply efficiency improve price signals for energy consumers. (Time-of-day pricing).  Allow Victorian consumers to better manage their energy Provide more detailed information about consumption Save money Reduce greenhouse gas emissions.  Mandated rollout of interval meters Two-way communications All Victorian electricity consumers with an annual usage less than 160 MWh.

6 6 Background of AMI Project  Essential Services Commission (ESC) decision of 2004 to rollout manually read interval electricity meters to most customers – referred to as IMRO (Interval Meter Roll Out).  In 2005 AIMRO study found need to add two-way communications to the IMRO meters. Victorian Government decision to mandate statewide AMI deployment and to co-ordinate the project to achieve this.  March 2006 DOI established Industry Strategy Group & several working groups to specify minimum functionality & plan rollout, to all customers consuming <160MWh per annum.  Enabling legislation passed by Vic Parliament on 22 August

7 7 Status of The AMI Project  Starting in 2008, some 2.4 million new “smart” meters will be installed over a 4 year period, across 5 DB’s.  The AMI project was established in March  Trials of 10 AMI technologies was started in December 2006 and will run for 6 months.  With the customer response trials scheduled to be in place for summer of 2007/2008.  Minimum AMI Functionality Specification release1.0 Oct.2007  Minimum AMI Service Levels Specification release1.0 Oct. 2007

16 Water and Gas Metering  Appears to be no driver for interval data  Data required to be sent: Meter number – say 12 digits Meter reading – encoder output not pulse output – say 6 digits Error codes (eg: tamper) Battery status  Appears there is nothing to control  Hence - communications needs to be only one way  Radio is predominant AMR technology  Range of reception – up to Km or more - hence have need for fewer data concentrators than DLC

17 Technology Challenges  Interface with HAN by using Zigbee module and management of in home display; home automation devices?  Concentrator with multi communication interface:  Wi-Fi/ WiMax; Zigbee; 3G etc?  NMS with dynamic mesh topology, routing in DLC?  Installation for large scale DLC meters by site management?  NMS open communication protocol?

19 Degrees of Openness

20 The Current Victorian Approach  That is, the open standard Zigbee AMI profile is likely to be prescribed for the HAN, and the connections to the B2B hub and MSATS are already open standards.
