Arizona’s Energy FutureRenewables + Energy Efficiency + Smart Technologies =

More Control for Customers

August xx, 2011

In 2009, a Long-Term Energy Vision Was Shared by 23 Arizona Groups

• Environmental groups• Business associations• Community groups• Arizona Corporation Commission• Residential Utility Consumer Office• Arizona Public Service

That Shared Vision Is Important to Arizona

• Aggressive goals for renewable energy

• Ambitious energy efficiency targets

• Maintain reliability and upgrade power grid

• Implement smart technologies to give customers greater choice and control

Energy Efficiency Saves Customers Money and Reduces Spending on New Power Plants

• The cheapest kilowatt-hour is the one never used

• Energy efficiency is a viable resource, just like natural gas or coal

• APS will invest nearly $800 million over 5 years to help customers reduce energy usage

• Every megawatt saved = 250 homes off the grid

Renewable Energy (Megawatts)

Smart Technologies: control and options for customers; efficiency, responsiveness for utility• Nearly 610,000 smart meters installed –

greater flexibility in rate, demand response development

• Self-healing grid pilot project in Flagstaff shows potential

• Home Energy Information Pilot initiates smart thermostat / in-home display / appliance control elements

• Infrastructure improvements over last two years – 6 substations and 493 miles of distribution lines

Flagstaff Smart

Grid pilot reduced

customer outage minutes by 66%.

Modernized Rates Will Encourage Energy Efficiency Investment

• Today’s outmoded rate structure dates from the early 1900s

• APS is modernizing rates to align its energy efficiency interests with those of customers

• Energy efficiency gains will reduce the need for new power plants

• Customers will also see greater predictability with modernized rates

APS Fossil Energy Growth by 2025 (Megawatts)

Like the 2009 Settlement, the 2012 Rate Case Seeks Benefits for Customers, APS and Arizona• For customers . . .

– Continuing support for energy efficiency and renewables

– Greater choice and control – More predictable and consistent rates– Fewer rate cases

• For APS . . . – Modernized rates to support energy efficiency,

renewables and grid upgrades– Ability to achieve Arizona’s energy goals

• For Arizona . . . – A growing renewables industry and jobs– Progress toward a sustainable energy future

We’ve Tightened Our Belt And Productivity Remains High

APS is working to limitcurrent and future rate increases by diligently managing costs.

• Achieved $37 million in cost savings in 2010

• Reduced staff by 380 positions

Even with 2012 Proposed Increase, APS Rates Beat Inflation

Typical Customer Could Easily Offset Increase with APS Program

• Typical Customer – 1,100 kWh per month

• Rate request potential increase of about $8.36

• Customer programs and incentives can help reduce electricity usage– 10 CFLs can offset up to 33% of rate

increase– Participation in the refrigerator

recycling program can save enough to cover rate increase

– APS offers 9 programs to reduce electricity usage without change in lifestyle

APS Makes Major Contributions to Arizona’s Economy, Communities and Jobs2010 Economy and Jobs Impact• Contributed $3.4 billion to the

economy• Purchased almost $1 billion Arizona

goods & services• Paid $408 million Arizona taxes • Supported 5,600 Arizona jobs and

$436 million of total income

Community Impact• 6,700 Employees • $4 million to United Way• 165,000 volunteer hours• Limited-income assistance

We’re Asking the ACC to Continue Supporting Arizona’s Ambitious Goals

• Energy efficiency and renewable goals among the most ambitious in the nation

• This work will increase customer bills by about 6.6%, on average

• Continues shared, longer-term vision established via 2009 rate settlement
