Key Statistics


Serve over 1.1 million customers


Largest IOU in Arizona


Serving
½ of Arizona’s
population in
11 of 15 Arizona counties


Peak demand ~7,100 MW


Owns and operates about 6,000 miles
of transmission lines
and 28,000
miles of distribution lines


Over 36,000 square miles of territory


2012 Energy Innovation Recognition

#4 Most Intelligent Utility

Top 10 in Smart Grid

#3 in Solar Deployed



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
