Smart Grid at APS

The primary objectives of deploying a smarter grid

are to:

• Optimize System Reliability & Performance

• Empower Customers

• Manage Alternative Energy

APS is piloting and/or implementing

over 20 advanced grid

modernization technologies in

order to meet these key objectives

Major Elements of the Smart Grid

AMI (Advanced Metering Infrastructure): The collective system of

advanced meters, communicating devices, and data management system

required to provide wireless electric metering and two-way

communications to customers.

Smart Circuits: A transmission or distribution circuit that utilizes

communication, monitoring, and/or automated devices to improve

visibility, reliability, and overall performance of the circuit.

Strategic IT: The communications, control

systems, network operations, and data

management systems required to serve the

overall needs of the enterprise in a secure and

reliable manner.

APS Strategic IT Investments

• Infrastructure Planning and Improvements

– Fiber for all new 69 kV lines and above; less than

69 kV on a strategic basis

– Backhaul/last-mile planning

– Development of real-time/near real-time data

collection, data management, and warehousing

• Security Architecture

– Multi-layered security integral from design to

operation

• Operational Excellence

– Communications backbone provides foundation to

deploy and operate smart grid systems to achieve

optimal availability

– Analyze and leverage opportunities with other

utilities and partners

Consumer Focused Pilots

Home Energy Information Pilot (Residential)

• Program Types being tested:

– Peak Event Pricing with Enabling Technology

– A/C Direct Load Control

Smart Phone & PC App

– Pre-Pay Energy Service

• Targeting both consumption and demand reduction

• Rigorous assessment of technology & consumer behavior

Electric Vehicle Time-of-Use Rate

• Provides a super off-peak rate of only 4.2 cents from 11 pm – 5 am

• Equivalent to filling up the car for only 37 cents per gallon

Smart Grid Lessons Learned

Business Case Challenges

– High reliability (Top Quartile – 2009 EEI, SAIFI, CAIDI, SAIDI)

– Adequate Near-Term Capacity Supply

– Lack of Fiber in Distribution Infrastructure

Infrastructure Challenges

– Large Rural Service Territory

– Communication Infrastructure

is Critical for Success

Governance Requirements

– Significant Cross-Functional

Collaboration Required

– Robust Internal Education and

Integration Campaign is

Critical!
