smart grid why
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

ami smart meters
AMI / Smart Meters
  • 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
