Challenges andBenefits of AMIDevelopment in theUSABrian K. SealTechnical Executive, EPRIAPEC Workshop on AddressingChallenges in AMI Deploymentand Smart Grids in APECAugust 24th & 25th , 2011

U.S. Electricity Cost Profile Average ResidentialConsumption 925KWh Average MonthlyCost 103 Median HouseholdIncome 50,000/yr Cost of Electricity 2.5% of AnnualIncome 2011 Electric Power Research Institute, Inc. All rights reserved.3

Diversity Among U.S. Utilities3,270 Utilities in the United States 210 Investor Owned 2000 Municipalities 900 CooperativesTennessee Valley DistributorsExample: 155 Munis and Cooperatives Sizes: 900 to 430,000 customers Employees: 3 – 2700 Density: 5 - 65 customers permile 2011 Electric Power Research Institute, Inc.

What is “Advanced Metering Infrastructure”?AMR (Automated MeterReading) 1990 to 2004AMI (Advanced MeteringInfrastructure) 2004 – ?One-way communicationTwo-way communicationMay be mobile, or intermittentFixed networkMonthly billing readsInterval dataNo outage reportingOutage reportingThe application is a given. Ineed to read meters. Whatsystems can I use for this?I need a flexible, two-waycommunication system, throughwhich I will do many things. 2011 Electric Power Research Institute, Inc.

AMI Supporting Distribution OperationsVoltage Data via AMIDistribution Equipment via AMIMeter Support of Voltage Measurements 2011 Electric Power Research Institute, Inc. All rights reserved.Meter Support of real-time Watts11

AMI Providing Real Time Consumption Feedback170,000 MetersFiber to the Home Network includes 125,000 Residential Every collector connected to fiber network 25,000 Disconnects Estimated 3-5 meters per collector at final build out 20,000 C/I 15 minute interval data sent every 15 minutes 2011 Electric Power Research Institute, Inc.

AMI Data Identifying Defective MetersSome meters failover an extendedperiod of timeUsage combined with meterdiagnostic flags identifysystematic issues 2011 Electric Power Research Institute, Inc. All rights reserved.1717

AMI Detecting Stressed AssetsTransformer load growth due to singlecustomer, 40 apartments, converted from gasto electric space heaters - usage increased by400% 2011 Electric Power Research Institute, Inc. All rights reserved.18

AMI Enabling Automatic Customer Phase ID Automatically maintain an accurate record of theprimary phase association of every customerTo benefit outage managementTo enable advanced volt/var optimizationTo guide phase balancingFor advanced distribution automation 2011 Electric Power Research Institute, Inc. All rights reserved.20

AMI Used to Improve Load Models Verifying customermodels Revampingcustomer classes Reclassifyingcustomers Converting staticmodels to dynamicmodels (switchingdecisions) 2011 Electric Power Research Institute, Inc. All rights reserved.21

AMI Improving Billing SupportAssisting in Back Bill EstimationMeter failuresdetected basedunusual changes inusage patternsWeather-adjustedprofiling used toestimate usageduring failure periodsand passed to billing 2011 Electric Power Research Institute, Inc. All rights reserved.2222

AMI Challenge: Standards at All LayersOSI ModelExample AMI BuildupANSI C12.19, C12.22UDP/TCP/ IPV6? RPL, ROLLIEEE 802.15.TG4ghttp://en.wikipedia.org/wiki/Ad hoc routing protocol list 2011 Electric Power Research Institute, Inc. All rights reserved.25

AMI Challenge: No Dedicated RF 003-allochrt.pdf FCC: No dedicated RF spectrum for AMI Licensed vs. unlicensed question – liability associatedwith ISM band from new products Sub 1GHz propagation characteristics needed 2011 Electric Power Research Institute, Inc. All rights reserved.28

AMI Challenge: Wired vs. Wireless Increasing demand for wireless spectrum for cell phone, media, &entertainment (mobile individuals, mobile vehicles) Houses and meters are not mobile, do not require a wireless solution Availability of broadband connectivity to customer premises rising Cost of wired/fiber systems (private vs. shared debate, cyber securityconcerns) 2011 Electric Power Research Institute, Inc. All rights reserved.29

Expected AMI Evolution:More Data, More Often Real-time collection Additional devices/applications Shorter intervals Additional quantities Back-of-the-envelopecalculation:“All-In” AMI is lessthan one browse toyahoo.com 2011 Electric Power Research Institute, Inc. All rights reserved.32

Expected AMI Evolution:GPS in the Meter (and other devices) Exact asset location Precision time-stamping– Support for advanced faultlocation– Cause and effect analysis tracing events– Improved customer phaseidentification– Improved customer transformerassociation 2011 Electric Power Research Institute, Inc. All rights reserved.33

Summary Observations AMI deployment level still low nationally Utilities focused on getting metering and billing workingfirst, will focus on “additional benefits” later Integrated service disconnect switches showing greatpromise Flexibility required in integrating customer devices AMI performance is trending upward to support ancillaryfunctions Value of historical AMI data is immediate, real-time datause is emerging, direct sharing of the AMI network isuncertain 2011 Electric Power Research Institute, Inc.
