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

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

Status of The AMI Project ØStarting in 2008, some 2. 4 million new “smart” meters will be installed over a 4 year period, across 5 DB’s. ØThe AMI project was established in March 2006. ØTrials of 10 AMI technologies was started in December 2006 and will run for 6 months. ØWith the customer response trials scheduled to be in place for summer of 2007/2008.

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

Technology Challenges ØInterface with HAN by using Zigbee module and management of in home display; home automation devices? ØConcentrator with multi communication interface: ØWi-Fi/ Wi. Max; Zigbee; 3 G etc? ØNMS with dynamic mesh topology, routing in DLC? ØInstallation for large scale DLC meters by site management? ØNMS open communication protocol? 17 17

Degrees of Openness 19 19

The Current Victorian Approach ØThat is, the open standard Zigbee AMI profile is likely to be prescribed for the HAN, and the connections to the B 2 B hub and MSATS are already open standards. 20 20
