AMI Implementation Drivers
o Business Benefits –— Foundational technology
o Will support Bill Redesign (Informational Demand), Smart City, Smart Homes and Volt-Var Optimization
— Meters report back line side power status, voltage and phase information and renewable system voltage information
— Automation for new service connects and disconnects
o Customer Benefits –— Customer can initiate and receive faster service connect, disconnect and re-
connect— Customer can receive improved outage and restoration information on their
mobile devices (ADMS)

ADMS – What is it?
o Advanced Distribution Management Systemo Real-time operational visibility – Operator Situational Awarenesso Control/monitoring & outage managemento Supports grid automation & optimizationo Advanced analysis of current grid conditionso Foundation for Distribution Modernization projects
o All distribution field data leads to ADMSo Substation SCADA, AMR/AMI Meters, Grid Sensors & Field Device
Controllers
o Future management of Distributed Energy Resourceso Demand Response (DR)o Distributed Energy Resource Management (DERMS)
8
ADMS Project Benefits
o Improved distribution grid reliabilityo Proactive optimization of grid resourceso Power flow visualization/voltage controlo Fault location/short circuit analysis
o Increased asset utilizationo Improved load balance/extending asset lifeo Prioritized maintenance/system reinforcement
o Increased customer satisfactiono Improved reliability/power quality
o Simplified operations systemo Common application user interface & user/support trainingo Standardized support team skill setso Shared hardware platforms
9
Business Benefits
o Evolving the capability of the distribution systemo Voltage optimization & system reinforcement prioritization
o Coordination of voltage control devices– Load Tap Changers/Capacitor Banks/Regulators & Inverters
o Optimize Distribution Energy Resources – Compensate for growing Distributed Energy Resoruce production
using forecasts– Defer/Reduce traditional distribution circuit upgrades by optimizing
existing systemo Use ADMS for select “behind the meter” equipment as a bridge to a future
DERMS solution

Key Milestones
11
o October & Novembero Start User/Operator/DOCS Trainingo Finish Site Acceptance Testingo Parallel Operation
o December and Januaryo User Acceptance Testingo TEP/UNSE Go Live
Next Steps
o More field devices for ADMSo Researching the use of the AMI drop-in network for supporting
communications for field deviceso Line sensorso Capacitor bankso Street Light control
o DERMS system for integration of devices on the customer side of the metero Efforts underway to create a multi-year roadmap for DERMS integration
