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
•
