IN THE MATTER OF THE APPLICATION OF ARIZONA
PUBLIC SERVICE COMPANY FOR A HEARING TO
DETERMINE THE FAIR VALUE OF THE UTILITY PROPERTY
OF THE COMPANY FOR RATEMAKING PURPOSES, TO FIX A
JUST AND REASONABLE RATE OF RETURN THEREON, TO
APPROVE RATE SCHEDULES DESIGNED TO DEVELOP SUCH
RETURN DOCKET NO. E-01345A-08-     

                  APPLICATION

I. INTRODUCTION

     APS’s 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 September 30, 2005 through July 1, 2009, APS will have placed

another $928 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.

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 Application for a permanent base rate increase in non-fuel rates of $252.6 million. The requested increase is based on adjusted test year sales and expenses for the Company’s jurisdictional electric operations during the twelve months ending September 30, 2007 (“Test Year”), and APS is requesting the increase to become effective no later than July 1, 2009.SeeA.A.C. R14-2-103 (B) (11).

     In addition, APS is seeking to increase its base fuel cost by $119.1 million over the level established in the Company’s last rate proceeding ($101 million over the Test Year level of fuel costs), effectively reclassifying current Power Supply Adjustor (“PSA”) revenues as base fuel revenues as called for in the Commission-approved Plan of Administration for the PSA. Although the Company’s Application herein reflects this fuel cost increase as part of the total base rate increase ($371.7 million) shown on Schedule A-1 of the Commission’s Standard Rate Case Filing Requirements (“SFR’s”), after taking into consideration the reclassification of such fuel costs to base rates, the net increase in base rates would be $265.5 million, as is also shown on Schedule A-1.¹

¹  This is composed of a $252.6 million non-fuel related increase plus a $12.9 million effective increase in fuel-related rates.

-2-

     The requested increase in non-fuel base rates includes an $86.6 million allowance for attrition caused by regulatory lag from the end of the Test Year to 2010. 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 new APS customers at a new service location. Thus, if such proposal is adopted and taking also into consideration the reclassification of fuel costs from PSA rates (which APS customers are already paying) to the base fuel rate described above, the impact of the instant request on APS customer bills in 2009 will be considerably less than $265.5 million.²

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 7.2% on equity compared to the 10.75% found reasonable by Decision No. 69663.SeeSFR Schedule F-1.³ Absent meaningful non-fuel rate relief in this proceeding, equity returns will fall to 6.8% next year and a paltry 6.1% the following year.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 Application, APS has proposed several specific adjustments to the historical Test Year that will address the undeniable impacts of attrition — impacts that the Commission must address in this proceeding and impacts that APS can no longer endure

2

Assuming the Commission would authorize the full $53 million in new Impact Fees (and also that projections of new APS customers in 2010 materialize); the net change in present customer rates would be $212.5 million ($265.5 million minus $53 million).

3

The Commission requires these “F” Schedules in every major rate filing. Their obvious purpose is to serve as a check on the degree to which the historical test period is, in fact, a reliable “proxy” for the period rates will become effective and to the extent it is not, allow the Commission to fashion the appropriate adjustments to such test period so that the Commission can satisfy its Constitutional mandate to authorize just and reasonable rates.

-3-

if it is to avoid a chronic pattern of rate cases that invariably result in inadequate relief and a diminished capacity to face the challenges of the future in a fast-growing state such as Arizona. 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 July 1, 2009 (and in some instances much sooner) as well as a specific attrition pro forma.

     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. 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 servicewithin 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

-4-

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 most 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 usedat the time it is being used to render the service are unjust, unreasonable and confiscatory, and their

-5-

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 $.0366 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; and (3) the Commission authorize a return of fair value rate base or otherwise account for attrition in a manner that allows APS an opportunity to earn an 11.5% return on equity after the rates established in this proceeding become effective.

-6-

      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 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 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

-7-

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.

⁴ This Application does not include SFR Schedule E-6 because such schedule applies only to a “combination utility” within the meaning of A.A.C. R14-2-103(A)(3)(q), which does not include APS.

-9-

(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 $252.6 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 $.0366 per kWh, thus increasing base rate fuel revenues by $119.1 million.
(e)	APS prudently acquired the Yucca Units, and such Units are used and useful.
(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

-10-

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 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 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;

-11-

D.	issue a final order approving the new or modified rate and service schedules included with the Company’s Application, as well as the freezing and/or cancellation of certain schedules, all with an effective date no later than July 1, 2009;
E.	issue a final order authorizing APS’s proposed depreciation and present amortization rates and classifications;
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; and,
G.	grant the Company such other relief as the Commission deems just and proper.

     RESPECTFULLY SUBMITTED this 24th day of March 2008.

Notes

* The $371.7M revenue increase requested above for base rates includes $119.1M due to the Company’s request to increase the base fuel rate from 3.25¢/kWh (as authorized in Decision No. 69663) to 3.66¢/kWh. $106.2M 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 10.05% or $265.5M. This increase could be further reduced by as much as 2% if the proposed Impact Fee is approved to recover a portion of the proposed attrition proforma.

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 were $1.76, $2.70, $2.95, $1.40 for 2005, 2006, test year ended 9/30/2007, and adjusted test year ended 9/30/2007, 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 9/30/2007, and adjusted test year ended 9/30/2007, respectively.

Note:

*	Under FERC regulations, short-term debt is utilized as a source of financing on Construction Work in Progress, therefore recoverable through AFUDC provisions. For the unadjusted test year ending 9/30/2007, actual short-term debt was $150.0 million. Had the short-term debt been included in the capitalization ratio, it would have accounted for 2.33% of the total capitalization.

APS’s common stock shares have remained constant at 71.3 million, even though Pinnacle West has increased its equity investment in APS, and 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 $2.95 for the test year ended 9/30/2007.
