Powering Growth, Delivering Value2 FORWARD LOOKING STATEMENTS This presentation contains forward-looking statements based on current expectations, including statements regarding our earnings guidance and financial outlook and goals. These forward-looking statements are often identified by words such as “estimate,” “predict,” “may,” “believe,” “plan,” “expect,” “require,” “intend,” “assume” and similar words. Because actual results may differ materially from expectations, we caution you not to place undue reliance on these statements. A number of factors could cause future results to differ materially from historical results, or from outcomes currently expected or sought by Pinnacle West or APS. These factors include, but are not limited to: our ability to manage capital expenditures and operations and maintenance costs while maintaining reliability and customer service levels; variations in demand for electricity, including those due to weather, the general economy, customer and sales growth (or decline), and the effects of energy conservation measures and distributed generation; power plant and transmission system performance and outages; competition in retail and wholesale power markets; regulatory and judicial decisions, developments and proceedings; new legislation or regulation, including those relating to environmental requirements, nuclear plant operations and potential deregulation of retail electric markets; fuel and water supply availability; our ability to achieve timely and adequate rate recovery of our costs, including returns on debt and equity capital; our ability to meet renewable energy and energy efficiency mandates and recover related costs; risks inherent in the operation of nuclear facilities, including spent fuel disposal uncertainty; current and future economic conditions in Arizona, particularly in real estate markets; the development of new technologies which may affect electric sales or delivery; the cost of debt and equity capital and the ability to access capital markets when required; environmental and other concerns surrounding coal-fired generation; volatile fuel and purchased power costs; the investment performance of the assets of our nuclear decommissioning trust, pension, and other postretirement benefit plans and the resulting impact on future funding requirements; the liquidity of wholesale power markets and the use of derivative contracts in our business; potential shortfalls in insurance coverage; new accounting requirements or new interpretations of existing requirements; generation, transmission and distribution facility and system conditions and operating costs; the ability to meet the anticipated future need for additional baseload generation and associated transmission facilities in our region; the willingness or ability of our counterparties, power plant participants and power plant land owners to meet contractual or other obligations or extend the rights for continued power plant operations; and restrictions on dividends or other provisions in our credit agreements and ACC orders. These and other factors are discussed in Risk Factors described in Part I, Item 1A of the Pinnacle West/APS Annual Report on Form 10-K for the fiscal year ended December 31, 2014 which you should review carefully before placing any reliance on our financial statements, disclosures or earnings outlook.

Powering Growth, Delivering Value6 2015 2016 2017 RETAIL SALES GROWTH (WEATHER-NORMALIZED) YoY Retail Sales Before Customer Programs Energy Efficiency & Customer Conservation Distributed Generation • Weather-normalized retail sales growth on average about 0.5-1.5% for 2015- 2017 after impacts of energy efficiency, customer conservation and distributed renewable generation initiatives (excluding Lost Fixed Cost Recovery) Distributed Generation (DG) Impact • DG makes up 0.5% (or less) of the negative impact to retail sales growth as shown in the chart; equates to approximately 60 GWh out of our total retail sales of over 28,000 GWh • Average residential rooftop solar system produces 10,000 – 12,000 KWh per year (average metro-Phoenix customer’s usage is nearly 15,000 KWh)
Powering Growth, Delivering Value7 KEY DATES FOR RATE DESIGN 2012 2013 2014 2015 • APS proposed stakeholder conference to explore net metering • Spring: Conducted series of Technical Workshops on Net Metering • July: 2014 RES filing • November: ACC decision on net metering; recognized cost shift and implemented $0.70 per watt charge effective January 1, 2014 • Mar–Aug: Innovations and Tech Development Workshop Series • April 15: Initial quarterly filing on rooftop solar installations • May/June: Value and Cost of Dist. Gen. Workshop Series • Aug. 12: ACC voted to lift decision to require a rate case filing in 2015 • Fall: Ongoing discussions on rate design process • Time of Use rates initiated - Nearly half of our residential customers are on TOU rates • Residential demand rates started due to central air conditioning load (currently about 10% of customers have a rate with a demand charge) Early 1980’s • April 2: Grid Access Charge filing request with ACC to increase charge for future solar customers to $3.00 per kW from $0.70 per kW, per month • Rate design discussions and rate case or another proceeding 2015+
Powering Growth, Delivering Value8 Rate Design Principles 1. Customer-focused 2. Forward-Thinking 3. Affordable & Fair Rate Design Modernization Steps: • Grid Access Charge filing on April 2, 2015 – Interim solution – Seeking increase to $3.00/kw (or about $21/month) from $0.70/kw* – Solar customers also have option to enroll in an existing rate plan, that includes TOU rates and a demand charge – Requesting effective date of August 1, 2015 – Current rooftop solar customers would be grandfathered under existing agreements • Other modifications to be discussed in a rate case or another proceeding – Align TOU or peak vs. off-peak rates more closely with wholesale rates – Align peak rate times with load peak – Broaden use of demand charges GRID ACCESS CHARGE REQUEST IS NEXT STEP IN MODERNIZING RATE DESIGN Fixed Costs 69% Variable Costs 31% Costs – APS Residential Classes (2010) Fixed Charge Revenue 10% Variable Charge Revenue 90% Revenue – APS Residential Classes (2010) Rate design changes needed to align fixed costs and revenue * In Decision No. 74202, Arizona Corporation Commission found that an interim charge of $3.00 per kW per month is reasonable for new DG customers, although the Commission set the initial charge at $0.70 per kW.
