APS Overview

Smart Grid
–

Why?

The primary objectives of deploying a
smarter grid are to:


•
Optimize
System Reliability & Performance

•
Empower Customers

•
Enable Alternative Energy

APS is piloting and/or
implementing a number of
advanced technologies in order
to meet these key objectives

•
Deployment of nearly 1,000,000 “Smart
Meters” by end of 2013


•
Over 85% way completed with meters in
Phoenix, Prescott, Yuma, and Flagstaff

–
More than 890,000 meters deployed


•
Remote meter reading, connect/disconnect,
and rate change

–
Over 1,000,000 field orders avoided to
date


•
Receiving more than 23,000,000 intervals
per day


•
Greater customer information and flexibility


•
Operational and planning benefits
