AMI Technology Maturity Many AMI provider choices – EPRI tracks 26 different companies regularly –Some have many years of 2-way communication system experience, others are new entrants applications Solid state metering is quite advanced –Commitments to production capacity Communication system still evolving –Latencies sometimes longer than expected –Throughput l at times lower than expected Early on in provision of back office services Strong effort underway to achieve plug and play Meters more mature than communications systems Choices and experience are expanding Q2: How has the technology matured in the past several years? Complex data management system at early stage of deployment

Phased Installation “A phased and constantly monitored approach to AMI rollout –Allows moving forward with provisions to adjust as circumstances become more certain –Fosters performance gathering and verification of benefits along the way –Limits technology obsolescence risks –Takes advantage of the collective, large-scale experiences of others Better understanding of complementary of AMI with other Smart Grid investments But, scale and scope of AMI investments and operation favor all or nothing investment decisions –Communication network is the backbone Q3: Are there advantages to phasing, either through technology deployment or starting with a particular customer classes?

Cost of a Wait and See Strategy A comprehensive and thoughtful business cases will identify the costs of waiting Some considerations –How fast would the investment pay for itself? In terms of hard benefits In terms of incremental soft benefits Difficult to generalize (lessons learned) from utilities who have recently deployed AMI –Some have recent AMR investments –Some driven by larger considerations –Some have especially favorable circumstances Q4: What are the “costs” to a utility of not proceeding in the next 6 years with a move toward automated 2-way communication with our customers?

8. 8 © 2012 Electric Power Research Institute, Inc. All rights reserved. Who is Installing AMI? EPRI estimates that 150 million residential electric meters are in use –About 60% are electromechanical (mostly read the dial values) –About 40% are AMR (drive-by electronic reading) –About 6-% are AMI (Two-way communication to read and program) Important trends –Electromechanically meters have a very long lifetime (100 years) –They are being replaced with solid state meters with a lifetime of ~15 years. –Ceiling on technology and economic obsolescence risk About 6% of meters (* million) are AMI today 40 million planned by 2015 References: http://www.coincident.com/#visualizationhttp://www.coincident.com/#visualization (tracks AMI installation intentions and realizations) Q5: What % of large urban utilities have launched or will launch AMI deployment in the next few years?
