THIRD QUARTER 2017 RESULTS

Third Quarter 20172
FORWARD LOOKING STATEMENTS AND
NON-GAAP FINANCIAL MEASURES
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,”
“project” 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 high reliability and customer service
levels; variations in demand for electricity, including those due to weather seasonality, 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, ballet initiatives and regulation, including those relating to environmental
requirements, regulatory policy, 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 and of debt and equity capital investments; 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, including 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, economic and other concerns surrounding coal-fired generation, including
regulation of greenhouse gas emissions; 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 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, 2016 and in Part II, Item 1A of the Pinnacle West/APS Quarterly Report on Form 10-Q for the quarter ended June 30, 2017, which you
should review carefully before placing any reliance on our financial statements, disclosures or earnings outlook. Neither Pinnacle West nor APS assumes any obligation
to update these statements, even if our internal estimates change, except as required by law.
In this presentation, references to net income and earnings per share (EPS) refer to amounts attributable to common shareholders.
We present “electricity gross margin” per diluted share of common stock. Gross margin refers to operating revenues less fuel and purchased power expenses. Gross
margin is a “non-GAAP financial measure,” as defined in accordance with SEC rules. The appendix contains a reconciliation of this non-GAAP financial measure to the
referenced revenue and expense line items on our Consolidated Statements of Income, which are the most directly comparable financial measures calculated and
presented in accordance with generally accepted accounting principles in the United States of America (GAAP). We view gross margin as an important performance
measure of the core profitability of our operations.
We refer to “on-going EPS” in this presentation, which is also a non-GAAP financial measure. 2017 and 2018 on-going EPS are currently projected to be the same as
2017 and 2018 GAAP EPS, respectively. We believe on-going earnings provides investors with a useful indicator of our results that is comparable among periods
because it excludes the effects of unusual items that may occur on an irregular basis.
Investors should note that these non-GAAP financial measures may involve judgments by management, including whether an item is classified as an unusual item.
These measures are key components of our internal financial reporting and are used by our management in analyzing the operations of our business. We believe that
investors benefit from having access to the same financial measures that management uses.

Palo Verde Generating Station
− Palo Verde will continue to have two refueling outages each year (18 months cycles for each of
the three units)
− APS’s share of the annual planned outage expense at Palo Verde has been between
$18 - $22 million per year since 2013
− Equipment testing, inspections, and plant modifications are performed during the outages that
cannot be done while the unit is online
− Outage duration and cost are driven by scope of planned work as well as emergent work
identified during the outage
Gas/Oil Plants
− No planned cycles; major maintenance outages are based on run hours and/or the number of
starts and overall plant condition
− Increasing levels of solar generation, participation in Energy Imbalance Market, and low gas
prices have resulted in increased starts
Coal Plants
− Major maintenance outage cycles are typically between 6 to 8 years
PLANNED OUTAGE
CYCLES
The length of time between
outages varies from plant to plant

balancing account

Distributed Generation
• New DG customers eligible for TOU rate with Grid Access Charge or Demand rates
• Resource Comparison Proxy (RCP) for exported energy of $0.129/kWh in year one
APS Solar Communities
• New program for utility-owned solar distributed generation, recoverable through the Renewable

million per year
Other Considerations
Rate Case Moratorium • No new general rate case application before June 1, 2019 (3-year stay-out)
Self-Build Moratorium
• APS will not pursue any new self-build generation (with exceptions) having an in-service date prior

replacing with 5 new, fast-ramping, combustion turbine units
– Four Corners Power Plant: Installing Selective Catalytic Reduction (SCR) equipment to comply
with Federal environmental standards
1 APS will calculate the capital carrying charge using the 5.13% embedded cost of debt established in the 2017 Rate Review Order.
