Item 8.01. Other Events

2008 General Rate Case

     On June 2, 2008, Arizona Public Service Company (“APS”) filed with the Arizona Corporation Commission (the “ACC”) updated financial statements, testimony and other data in the general rate case originally filed on March 24, 2008. As requested by the ACC staff, the updated information reflects a test year ended December 31, 2007, rather than the September 30, 2007 test year used in APS’ original filing. As a result of the updated filing, APS is requesting a net rate increase of $278.2 million for retail customers effective no later than October 1, 2009. The original filing requested a net rate increase of $265.5 million for retail customers. As proposed by APS, the updated request would result in an average rate increase of 8.5% for existing customers plus the establishment of a new growth-related impact fee charged to new connections.

     The key financial provisions of the updated request include:

• an increase of $264.3 million in non-fuel base rates and a net increase of $13.9 million for fuel and purchased power costs reflected in base rates, and recovery of up to $53 million of such increases through the impact fee;

• a rate base of $5.4 billion, which approximates the ACC-jurisdictional portion of the book value of utility assets, net of accumulated depreciation and other credits, as of December 31, 2007, subject to certain adjustments;

• the following proposed capital structure and costs of capital:

	Capital	Cost of
	Structure	Capital
Long-term debt	46.2%	5.77%
Common stock equity	53.8%	11.50%
Weighted-average cost of capital		8.86%

• a base rate for fuel and purchased power costs (“Base Fuel Rate”) of $0.0388 per kilowatt-hour (“kWh”) based on estimated 2010 prices (an increase from the current Base Fuel Rate of $0.0325 per kWh including the reclassification of $170.0 million of fuel and purchased power revenues from the power supply adjustor to base rates); and

• an attrition adjustment of $79.3 million to address erosion in APS’ earnings and return on equity through 2010.

     The update also requests that the ACC adopt certain goals for APS to improve its financial strength which include: allowing APS’ internal cash flow generation to cover its operating and capital costs of providing service; stabilizing and improving APS’ credit ratings; and providing a meaningful and ongoing opportunity for APS to achieve a reasonable return on the fair value of its property. The other primary components of the updated request remain essentially unchanged from APS’ March 24, 2008 original filing. For additional information regarding APS’ original filing, which except as set forth above remains part of the updated filing, see “2008 General Rate Case” in Note 5 to Condensed Consolidated Financial Statements in the Pinnacle West Capital Corporation/APS Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2008.

Forward-Looking Statements

     This Report on Form 8-K contains forward-looking statements based on current expectations, and neither Pinnacle West Capital Corporation (“Pinnacle West”) nor APS assumes any obligation to update these statements or make any further statements on any of these issues, except as required by applicable law. Because actual results may differ materially from expectations, we caution readers not to place undue reliance on these statements. A number of factors could cause future results to differ materially from historical results, or from results or outcomes currently expected or sought by Pinnacle West or APS. In addition to the Risk Factors described in Item 1A of the Pinnacle West/APS Annual Report on Form 10-K for the fiscal year ended December 31, 2007, these factors include, but are not limited to, state and federal regulatory and legislative decisions and actions, including the outcome or timing of the rate case filed with the ACC on March 24, 2008, as updated on June 2, 2008; the outcome of regulatory, legislative and judicial proceedings, both current and future, relating to the restructuring of the electric industry and environmental matters (including those related to climate change); the ongoing restructuring of the electric industry, including decisions impacting wholesale competition and the introduction of retail electric competition in Arizona; fluctuations in market prices for electricity, natural gas, coal, uranium and other fuels used in our generating facilities, and supplies of such commodities; volatile market liquidity, any deteriorating counterparty credit and the use of derivative contracts in our business (including the interpretation of the subjective and complex accounting rules related to these contracts); power plant performance and outages; transmission outages and constraints; weather variations affecting local and regional customer energy usage; customer growth and energy usage; regional economic and market conditions, including the results of litigation and other proceedings resulting from the California and Pacific Northwest energy situations, volatile fuel and purchased power costs and the completion of generation and transmission construction in the region, which could affect customer growth and the cost of power supplies; ability of power plant participants to meet contractual or other obligations; the cost of debt and equity capital and access to capital markets; current credit ratings remaining in effect for any given period of time; our ability to compete successfully outside traditional regulated markets (including the wholesale market); changes in accounting principles generally accepted in the United States of America and the interpretation of those principles; the performance of the stock market and the changing interest rate environment, which affect the value of our nuclear decommissioning trust, pension, and other postretirement benefit plan assets, the amount of required contributions to Pinnacle West’s pension plan and contributions to APS’ nuclear decommissioning trust funds, as well as the reported costs of providing pension and other postretirement benefits; technological developments in the electric industry; the strength of the real estate market in SunCor’s market areas, which include Arizona, Idaho, New Mexico and Utah; and other uncertainties, all of which are difficult to predict and many of which are beyond the control of Pinnacle West and APS.

RETURN THEREON, TO APPROVE RATE SCHEDULES

AMENDED APPLICATION

I. INTRODUCTION

     As noted in its original Application dated March 24, 2008, Arizona Public Service Company’s (“APS” or “Company”) current rates and charges do not recover the cost of providing service today, let alone in the future. Consequently, they do not produce a reasonable return on the fair value of its property devoted to public service and are therefore unjust and unreasonable as a matter of law. Simms v. Round Valley Light & Power Co., 80 Ariz. 146, 294 P.2d 378 (1956); Arizona Consumers Council v. Arizona Corporation Commission, 200 Ariz. 85, 22 P. 3d 905 (App. 2001). Indeed, as the Company demonstrated in its last rate case, the rates established by Decision No. 69663 (June 28, 2007) were inadequate the day they were implemented. This is because earnings attrition continued from the end of the test period in that proceeding (September 30, 2005) through the date of Decision No. 69663 – some 21 months later – but was not recognized by such Decision in any meaningful fashion. Moreover, from the end of the September 30, 2005 test year used to set the rates authorized by Decision No. 69663 through

October 1, 2009, APS will have placed another $956 million (net jurisdictional investment) of facilities into service to its customers – none of which investment has been reflected in retail rates.

     Inadequate rates are not just a problem for investors or some abstract legal issue. They prevent APS from maintaining the financial strength it needs to do its job, which is to provide safe and reliable electric service to the public. Inadequate rates today also invariably lead to even higher rates to consumers in the future. Consistent with that theme, APS strongly urges the Commission to identify and adopt specific financial goals for APS that will assure the Company’s ability to build needed infrastructure, to adopt the new technologies, and to enhance the sustainability of Arizona’s economy. APS believes those goals should include: (1) reaching the regulatory equivalent of a “balanced budget” where APS is able to “pay as it goes” for the capital and operating costs of providing service; (2) first stabilizing and then systematically improving its credit metrics to achieve solid investment grade ratings (BBB+ or even A-); and (3) providing a meaningful and ongoing opportunity for APS to achieve a reasonable return on the fair value of its property.

     APS witness and President Donald Brandt will suggest one means of breaking out of the current downward spiral affecting the Company and moving forward to the future. Specifically, this would involve a post-order proceeding to be conducted the year after rates from this case are set to ensure both that APS has the opportunity to earn its authorized rate of return and a reasonable return on Fair Value, and that it is on target for long-term financial stability and improvement. Mr. Brandt’s proposal is likely not the only means to accomplish this purpose. Various Commissioners have suggested that Arizona look for creative solutions that are different from the “business as usual” approaches of the past to address the issues raised by Arizona’s growth and the impact of such growth, as well as commodity price inflation, on Arizona utilities and their customers. The Company looks forward to the opportunity of discussing these vital issues with the Commission, Commission Staff, and other interested parties. This rate

-2-

proceeding and the Company’s resource alternatives proposal (and perhaps other ongoing proceedings as well), provide a collective opportunity for the Commission to both formulate regulatory goals and implement procedures to make those goals possible of achievement.

II. APS REQUEST FOR HIGHER BASE RATES

     Pursuant to A.R.S. §§40-222, 40-250, 40-251 and A.A.C. R14-2-102 and R14-2-103, Arizona Public Service Company (“APS” or “Company”) hereby files the instant Amended Application for a permanent increase in non-fuel base rates of $264.3 million. As agreed to by the Company and Commission Staff, the requested increase is based on adjusted test year sales and expenses for the Company’s jurisdictional electric operations during the twelve months ending December 31, 2007 (“Test Year”). APS is requesting the increase to become effective no later than October 1, 2009. See A.A.C. R14-2-103 (B) (11).

     In addition, APS is seeking to increase its base fuel cost by $183.9 million over the level established in the Company’s last rate proceeding, effectively reclassifying current and anticipated Power Supply Adjustor (“PSA”) revenues as base fuel revenues as called for in the Commission-approved Plan of Administration for the PSA. The Company’s Amended Application is required by Commission rule to reflect this base fuel cost increase as part of the total base rate increase ($448.2 million) shown on Schedule A-1 of the Commission’s Standard Rate Case Filing Requirements (“SFR’s”). But, after taking into consideration the reclassification of such PSA revenues to base rates, the net increase in rates would be $278.2 million, as is also shown on Schedule A-1.¹ And, even this figure overstates the potential impact in 2009 of the Company’s request on existing APS customer bills.

¹ This is composed of a $264.3 million non-fuel related base rate increase plus a $13.9 million effective net increase in fuel-related base rates.

-3-

     The requested increase in non-fuel base rates includes a $79.3 million allowance for attrition and measures the impact of regulatory lag through 2010, the first full year new rates would be in effect. APS is proposing to collect up to $53 million of that attrition amount through a new “hook-up” or “impact” fee that would be applicable only to APS customers at a new service location. Thus, if such proposal is adopted and taking also into consideration the reclassification of fuel revenues from PSA rates (which APS customers will already be paying by 2009) to the base fuel rate described above, the incremental impact of the instant request on APS customer bills in 2009 will be considerably less than $278.2 million.

III. APS RATES ARE AND WILL CONTINUE TO BE UNJUST AND UNREASONABLE ABSENT RATE RELIEF BASED ON CONDITIONS IN EFFECT WHEN THIS PROCEEDING IS DECIDED

     In 2008 (the first full year the rates established by Decision No. 69663 are to be in effect), APS will earn only 7.8% on equity compared to the 10.75% found reasonable by Decision No. 69663. See SFR Schedule F-1. Absent meaningful non-fuel rate relief in this proceeding, equity returns will fall to 6.2% next year and a paltry 5.4% the following year.² Id. The returns on fair value fall even more precipitously and are confiscatory by any definition of that term. Arizona Corporation Commission v. Arizona Public Service Co., 113 Ariz. 368, 370, 555 P.2d 326, 328 (1976)(“Prospectively, the rate may well become confiscatory” if it does not allow the company a fair rate of return.).

     In this Amended Application, APS has proposed several specific adjustments to the historical Test Year that will address the undeniable impacts of attrition. These are impacts that the Commission must address in this proceeding and impacts that APS can no longer endure because the alternative – a chronic pattern of rate cases that invariably result in inadequate relief and a diminished capacity to face the challenges of the future in

² Jurisdictional returns on equity are marginally better (8.4% and 6.3%) in 2008 and 2009, but they reach the same 5.4% by 2010.

-4-

a fast-growing state such as Arizona – is simply unworkable. These adjustments include the inclusion in rate base of plant under construction at the close of the Test Year but going into service prior to October 1, 2009 (and in some instances much sooner) as well as a specific attrition pro forma adjustment.

     All of the plant referenced above will be in service within two years of the close of the Test Year. Some of it, such as the new steam generators at Palo Verde, is already in service and providing substantial benefits to APS customers. Other examples include important environmental improvements to the Cholla plant (improvements necessary to keep that plant available to APS customers) that will be complete by this summer, as well as the new Yucca generating units under construction for improved reliability in Yuma. The Commission has authorized inclusion in rate base of post-Test Year plant on numerous occasions, including in both of the Company’s last two rate proceedings. And, the Arizona Supreme Court has gone so far as to characterize as “entirely reasonable” the Commission’s inclusion in rate base of plant that was anticipated to be in service within two years of when rates were set (and thus far more than two years following the then test period). Arizona Community Action Ass’n v. Arizona Corporation Commission, 123 Ariz. 228, 230, 599 P.2d 184, 186 (1979). See also Arizona Corporation Commission v. Arizona Public Service Co., 113 Ariz. 368, 371, 555 P.2d 326, 329 (1976)(“It is obvious that the Commission can consider matters subsequent to the historic test year. . . . Construction projects contracted for and commenced during the historical year may certainly be considered by the Commission . . . .”); Arizona Corporation Commission v. Citizens Utilities Co., 120 Ariz. 184, 189, 584 P.2d 1175, 1180 (App. 1978)(constitutional requirements “may, at the administrative level, require the Commission to consider post test year evidence on due process grounds.”).

     After making this and other pro forma adjustment to the Test Year to reflect known and measurable changes, APS made a further adjustment to account for the remaining

-5-

effects of attrition during the likely pendency of this case. Contrary to the assertion made in Decision No. 69663, significant attrition – and especially attrition that exists even prior to rates being established – is not supposed to be the normal outcome of ratemaking and cannot be “cured” simply by subsequent rate filings. Rather, attrition represents a breakdown of that ratemaking process that must be redressed by the Commission through specific regulatory actions. This was recognized in at least two prior APS rate decisions under circumstances startlingly similar to those now affecting APS. Decision No. 48139 (August 1, 1977) stated at pages 15-16: “Because this is for a historic period, the Company will never earn the rates allowed. Attrition will set in. . . . We think it is appropriate to allow a 4% attrition factor per year in the earnings of the Company.” Similarly, in Decision No. 51009 (May 29, 1980) at page 20, the Commission found that: “[T]he Commission may include a factor for attrition in determining what rates the company may be authorized to charge. . . .[B]y use of this approach, the Commission is attempting to evaluate, and compensate, for a very real phenomenon.” The Company’s proposed impact fee is intended to provide the Commission an option to collect much of this attrition without affecting current APS customers.

     By looking backwards to set rates in a time of substantial growth, with the implicit but erroneous assumption that costs and revenues will increase proportionately, the Commission’s rate setting practices necessarily prohibit the Company from realizing a fair return on its invested equity. Using a historical test year without accounting for known or reasonably anticipated attrition ensures that no rate set by the Commission will ever compensate the Company for the value of its property at the time the property is being used, as constitutionally required. Bluefield Water Works & Improvement Co. v. Public Service Commission of West Virginia, 262 U.S. 679, 690 (1923) [“Rates which are not sufficient to yield a reasonable return on the value of the property used at the time it is being used to render the service are unjust, unreasonable and confiscatory, and their

-6-

enforcement deprives the public utility company of its property in violation of the Fourteenth Amendment.” (Emphasis supplied.)]

     In addition, the rate increase sought is required to enable the Company to maintain its credit ratings, attract new capital on reasonable terms, and recover its costs of service. These criteria represent both the conditions necessary for APS to provide safe and reliable service to the public and those necessary to satisfy the Commission’s obligations under both the Arizona and United States Constitutions. Id. See also Arizona Corporation Commission v. Arizona Water Co., 85 Ariz. 198, 200, 335 P.2d 412, 414 (1959)(“[I]f [the Commission] refuses to consider all the relevant factors, the fair value of the properties cannot have been determined under our Constitution.”). As it is, this increase will not permit APS to recover past earnings shortfalls or fully earn a reasonable rate of return going forward on the fair value of its assets devoted to public service. Rather, the return resulting from the APS rate request will do no more than recover the Company’s capital costs necessarily and prudently incurred in rendering adequate utility service to customers.

IV. OTHER MAJOR COMPONENTS OF THE REQUESTED
INCREASE IN BASE RATES

     There are several major components of the Company’s request. Specifically, APS is seeking that: (1) the Commission recognize the higher fuel and purchased power expenses that are being incurred by the Company by increasing the base fuel rate from $.032491 per kWh to $.038783 per kWh; (2) the Commission allow APS to include in rates at cost of service the Yucca generation assets, the construction of which was specifically authorized by Decision No. 69400 (March 30, 2007), as well as other plant investments made prior to the time the rates requested in this proceeding will become effective; (3) the Commission authorize a return on fair value rate base or otherwise account for attrition in a manner that allows APS a reasonable opportunity to earn an 11.5% return on equity after the rates established in this proceeding become effective; (4)

-7-

the Commission establish as financial goals for APS the improvement in its internal generation of funds for construction to a level close if not equal to 100%, the reasonable opportunity to earn a reasonable return on an ongoing basis, and the improvement of its credit rating to at least a high BBB; and (5) the Commission implement in this proceeding a regulatory mechanism that can achieve these financial goals, which mechanism could include a post-order proceeding of the sort described in APS witness Brandt’s Testimony.

     APS is further requesting:

• changes to the Demand Side Management Adjustment Clause (“DSMAC”) to encourage and support additional cost-effective demand-side management, and also to the Transmission Cost Adjustor (“TCA”), both of which rate mechanisms were authorized by Decision No. 67744 (April 7, 2005), as described below and in the pre-filed testimony of the Company’s witnesses;

• approval of three new conservation and demand management rate provisions to encourage the efficient use of electricity and provide APS customers with the opportunity to better manage their energy costs;

• changes to the Environmental Improvement Surcharge (“EIS”), authorized by Decision No. 69663, to better facilitate and finance the implementation of new APS programs to reduce the impact of Company operations on the environment;

• continuation of its ability to defer certain costs related to its provision of net metering options, which deferral was first authorized by Decision No. 69663; and

• changes in or cancellation of specific service and rates schedules, as well as approval of its depreciation rates, as are also described below and/or in the pre-filed testimony of the Company’s witnesses and the attached SFRs.

     In addition to these and the changes to the EIS, TCA and DSMAC discussed above, APS is proposing several new rate programs or modifications of existing rates to

-8-

allow participating customers to better manage their energy costs and provide long-term benefits to the Company and its customers. These include a new residential time-of-use (“TOU”) option that reflects a “super peak” period of 3-6 p.m. during July, August and September – the three hottest months of the year – as well as a conservation tier to the Company’s most popular residential non-TOU rate. APS is also proposing, in response to a Commission initiative in Decision No. 69663, a “critical peak pricing” (“CPP”) program for commercial, industrial and other non-residential customers. This program will provide incentives for participating customers to shed significant electric load when called upon by APS for the top 90 hours of system demand during the year. APS’s existing TOU programs are already the most successful in the country both in terms of number of participants and percentage of customers participating, while the CPP proposal would be the first implemented by a Commission-regulated utility.

6. The Company respectfully requests that this Commission set a date for a hearing on this Amended Application such that new rates for the Company will become effective no later than October 1, 2009. At the hearing conducted pursuant to this rate request, APS will establish and hereby alleges that:

(a)	APS’s current rates and charges do not permit the Company to earn a fair return on the fair value of its assets devoted to public service and are therefore no longer just and reasonable.
(b)	The requested increase is the minimum amount necessary to allow the Company an opportunity to earn a fair return on the fair value of its assets devoted to public service, for preservation of the Company’s financial integrity and for the attraction of new capital investment on reasonable terms.
(c)	The Company requires additional permanent non-fuel base revenue of at least $264.3 million based on annualized test period sales in order to continue to provide, both now and in the future, adequate and reliable electric service to its customers as required by law.
(d)	APS should update its Base Fuel Rate to $.038783 per kWh, thus increasing base rate fuel revenues by $183.9 million.
(e)	APS prudently acquired the Yucca Units, and such Units are used and useful.

-11-

(f) The DSMAC approved by Decision No. 67744 should be retained but modified as set forth below and in the Company’s testimony and exhibits:

i.	the mechanism should recover DSM costs for approved programs in excess of the $10 million allowance in base rates on a prospective basis;
ii.	alternatively, if recovery of only historically incurred costs (including incentives) is retained, APS should be permitted to earn its full authorized cost of capital on such cost deferrals;
iii.	the 10% of savings incentive for successful DSM programs should be retained at this time, but the cap on APS’s share of such savings should be removed; and,
iv.	the DSMAC should recover, on a retrospective basis, incurred losses in margins (unrecovered fixed costs) attributable to Commission-approved DSM programs.

(g)	The EIS approved by Decision No. 69663 should be modified to allow for the timely recovery of environmental costs incurred by the Company.
(h)	The Company’s FERC-approved transmission rates should be directly reflected in rates to retail customers without specific Commission action through the TCA.

7. In addition to setting a hearing date, APS asks that the Commission issue a procedural order setting forth the prescribed notice for the Amended Application, establishing procedures for intervention, and providing for appropriate discovery. In this last regard, APS requests that to expedite such discovery, the Company should be authorized to serve all pleadings, testimony, discovery requests, answers and objections

electronically. Hard copy service would remain available to parties upon request or if the confidential nature of the information makes the use of electronic service impractical.

*      *      *      *      *      *

     WHEREFORE, THE COMPANY RESPECTFULLY REQUESTS that the Commission:

A.	issue a procedural order establishing a date or dates for the filing of testimony and the hearing of evidence concerning the Amended Application and also prescribing the time and form of notice to APS customers;
B.	issue a final order granting the Company the permanent base rate increase sought herein;
C.	modify the DSMAC, TCA and EIS as requested herein;
D.	issue a final order approving the new or modified rate and service schedules included with the Company’s Amended Application, as well as the freezing and/or cancellation of certain schedules, all with an effective date no later than October 1, 2009;
E.	issue a final order authorizing APS’s proposed depreciation and present amortization rates and classifications4;
F.	issue an order continuing the Company’s ability pursuant to Decision No. 69663 to defer certain costs related to the provision of net metering services;
G.	issue a final order establishing as financial goals for APS the improvement in its internal generation of funds for construction to a level close if not equal to 100%, the reasonable opportunity to earn a reasonable return on an ongoing basis, and the improvement of its credit rating to at least a high BBB;
H.	issue a final order implementing in this proceeding a regulatory mechanism or mechanisms that can achieve these

Notes

*

The $448.2M revenue increase requested above for base rates includes $183.9M due to the Company’s request to increase the base fuel rate from 3.25¢/kWh (as authorized in Decision No. 69663) to 3.88¢/kWh. $170.0M of the increase associated with the base fuel increase would have been charged to customers under the provisions of the PSA. Therefore the effective increase to customer rates net of the reduced PSA charges is actually 10.55% or $278.2M. This increase could be further reduced by approximately 2% if the proposed Impact Fee is approved to recover a portion of the proposed revenue requirement related to the attrition proforma adjustment.

Notes
*	2005 Other Income and (Deductions) includes regulatory disallowance on PWEC Units.
**	Optional for projected years. Lines 7 and 8 are calculated using the common stock shares of Arizona Public Service Company, as indicated by the SFRs. APS’s common stock shares have remained constant at 71.3 million, even though Pinnacle West has increased its equity investment in APS, and all APS shares are wholly owned by Pinnacle West Capital Corp. Pinnacle West’s common stock is publicly held and the PNW share count is more indicative of the increasing equity investment needed to support APS’s investment to serve its customers. APS’s earnings per share of Pinnacle West diluted common stock outstanding was $1.76, $2.70, $2.82, $0.98 for 2005, 2006, test year ended 12/31/2007, and adjusted test year ended 12/31/2007, respectively. APS’s dividends per share of Pinnacle West diluted common stock outstanding was $1.76, $1.70, $1.69, $1.69 for 2005, 2006, test year ended 12/31/2007, and adjusted test year ended 12/31/2007, respectively.

For the unadjusted test year ending 12/31/2007, actual short-term debt was $218.0 million. Had the short-term debt been included in the capitalization ratio, it would have accounted for 3.38% of the total capitalization.
