Vic Technology Trials
Trials Working Group was established in May 2006 to coordinateAMI technology trials
Trials Purpose:
• Confirm that available AMI technologies at the time couldsupport the envisaged AMI functionalities in Victoria underlocal environmental conditions
• Allow distributors to identify technologies relevant to theirnetwork area
• Identify potential vendors
• Improve cost understandings
Working Group Terms of Reference
• Minimise duplication, time & cost across distributors
• Ensure comparability of trials of different technologies
• Maximise sharing of learnings
• Ensure uniform reporting of results
• Vic andInterstate DBs
• Retailers
• Vic & FederalGovt
• EssentialServicesCommission
• NEMMCO
• ConsumerGroups

Trials Key Learnings(trials conducted across 2007)
• General
– Technologies, solutions and Vendorcapability were still emerging
– Long lead times to execute trials
– Confidentiality of vendor informationkey issue for coordinated trials
• High-Voltage Powerline carrier
– Concerns regarding limitedcommunications bandwidth &headroom for emerging HANrequirements
– Potential technical issues relating tointerference to electricity network
• Low Voltage Powerline Carrier
– Varying performance across vendors
– Concerns regarding limitedcommunications bandwidth &headroom for emerging HANrequirements
• Mesh Radio
– Sufficient communications capabilityto meet functional requirements
• GPRS
– Sufficient communications capabilityto meet functional requirements
