EXHIBIT 10.1 RATE SETTLEMENT AGREEMENT April 20, 1994 This rate settlement agreement ("Agreement") is entered into as of April 20, 1994, by Arizona Public Service Company ("APS" or the "Company") and the Staff of the Arizona Corporation Commission ("Staff") for the purpose of establishing revised rates and charges and related procedures for APS that are just, reasonable, and in the public interest. INTRODUCTION In 1991, the Arizona Corporation Commission ("Commission" or "ACC") approved a comprehensive and innovative settlement (the "1991 Settlement") between Staff and APS that sought to keep APS' customer rates as low as possible by directing the Company to further reduce its costs and operate more efficiently. Since the 1991 Settlement, APS has taken a number of aggressive steps to meet the Commission's goal of expense reduction and improved service. One of the fundamental principles underlying the 1991 Settlement was the Company's commitment to contain its costs, and thus its rates, through disciplined cost management. This commitment was underscored, at Staff's request, by the establishment of target price and cost levels which APS must meet without deterioration in service. The 1991 Settlement also set forth in detail the procedures for determining target price and cost levels and the regulatory and rate consequences of failing to meet those targets. Finally, the 1991 Settlement included a two-year moratorium on APS' ability to file for a permanent rate increase and set forth procedures for determining how APS' future rate filings would be handled. The rate moratorium required by the 1991 Settlement ended in December 1993. In addition, the procedures for limiting future rate increases will likewise lapse unless APS files a permanent rate increase application prior to January l, 1995. APS has indicated it has no present intention of filing such a rate increase application by that time and therefore the target pricing provisions contained therein will be of no further force and effect unless a new agreement is reached. The settlement described below represents the Staff's "report card" on APS' performance that the Commission ordered in the 1991 Settlement. APS has exceeded the Commission's cost reduction goals and has improved customer service. These accomplishments were only possible through the cooperative alignment of regulatory and corporate goals, the public commitment and accountability to such goals, and the dedicated efforts of Staff and APS. This progress toward improved utility performance should continue. The settlement described below is in the public interest and provides the company's customers with substantial benefits that would otherwise not be achieved either at all, or at least not without significant expenditure of public and private resources in protracted litigation. These benefits include (l) an immediate rate reduction of approximately 2.2%; (2) an additional moratorium on further permanent rate applications; (3) a comprehensive study of the impacts increasing competition in the electric utility industry may have on APS and its customers; (4) an increase in expenditures on renewable resources and DSM programs, and (5) a provision that will encourage APS to continue effective cost containment by allowing the Company to share with ratepayers cost savings achieved in the next several years. In addition, Staff has carefully reviewed APS' current financial condition, and believes the provisions of this Agreement should not adversely affect the Company's financial health; rather, it will sharpen management's focus on the challenges of the future in a manner that is beneficial to its customers and its shareholders. NOW, THEREFORE, Staff and APS agree to the following provisions which they both believe to be fair and reasonable and in the public interest: TERMS OF AGREEMENT A. REVENUE REDUCTION. For usage on or after the effective date of the Agreement, as determined in accordance with Paragraph S, APS jurisdictional rates will be decreased by approximately 2.2% (approximately $32.3 million annually, based on September 30, 1993 sales as adjusted). B. SETTLEMENT RATES. The revenue decrease provided for in Paragraph A of this Agreement shall be allocated among customer classes by means of a uniform .20 cents/kWh reduction in the energy charges for all APS rate schedules except those rate schedules set forth in Attachment A. In addition, and concurrent with this rate reduction, APS will be authorized to amend Schedule 1 of its tariffs. These revised tariff sheets are set forth in Attachment B. C. MORATORIUM ON AND PROCEDURES FOR FURTHER RATE CHANGES. i. APS shall not file for a change to its general rates and charges prior to December 31, 1996 ("Rate Moratorium Period"). Staff will likewise be subject to the same moratorium. This moratorium shall not apply to price changes pursuant to Paragraph P of this Agreement. ii. The next general rate application filed by APS will become effective and permanent as soon as practicable after the filing, but in no event later than 12 months after the filing. Such time limit shall not be extended and shall supersede any Commission regulation or legislative enactment which provides for a different period of time, unless the Commission determines that such time limit has become unreasonable due either to any amendment to the rate filing made by APS which substantially alters the amount of the requested rate change or substantially alters the facts used as a basis for the requested rate change, or to an extraordinary event not otherwise provided for. The provisions of this subparagraph shall not apply to any general rate application filed by APS after December 31, 1997. iii. During the six month period following the filing referenced in the preceding subparagraph, APS and Staff will act in good faith to use their best efforts to achieve a settlement on APS' filing and will submit a written report to the Commission at the end of that period on the outcome of such settlement activities. If a settlement is reached, Staff and APS shall promptly file a motion seeking Commission approval of the settlement, and the Commission shall accept or reject the settlement as soon as practicable after filing. iv. Neither APS nor Staff shall be prevented from seeking a change in rates prior to or after December 31, 1996 in the event of conditions or circumstances which constitute an emergency, such as the inability to finance on reasonable terms or material increases in the Company's cost of service as a result of federal, tribal, state or local laws, regulatory requirements or orders. Staff's review of such a request by APS for emergency rates shall focus on the existence of a substantial threat or harm to APS' ability to continue to provide reliable service. D. ESTABLISHMENT OF FUTURE RATE PRINCIPLES. APS will aggressively pursue the cost savings contemplated by Paragraph L of this Agreement with the goal of maintaining average residential prices beyond the Rate Moratorium Period at the proposed 10.45 cents/kWh level resulting from this settlement rate reduction. To meet this goal, APS will have to further reduce operating costs to offset increases in externally imposed expenses, such as interest and other capital costs, fuel and taxes. In addition, APS will require additional regulatory flexibility and pricing freedom to properly respond to the competitive forces and financial risks inherent in the larger customer market segments. Therefore, Staff will meet with APS in a good faith attempt to develop new pricing and operating procedures that are responsive to market conditions, competitive pressures in the electric utility industry, and the Commission's relationship to regulated utilities and their customers. In this endeavor, the parties agree to consider, inter alia, flexible pricing provisions, innovative procedures, and product pricing principles. The parties agree to provide a written report on their progress to the Commission within 12 months of the date of commission approval of this Agreement and will request prompt Commission approval of recommendations that will assist APS in achieving its residential price stability goals. E. PROPERTY INCLUDED IN RATE BASE. The rates and charges authorized herein fully include a return on the recorded book original cost of all jurisdictional APS assets (net of depreciation, amortization, and deferred income taxes and other deferred credits) as of September 30, 1993, excepting construction work in progress as of such date. However, nothing in this Agreement shall be construed as prohibiting Staff or any other party from pursuing new issues related to expenditures made or actions taken after September 30, 1993. F. AMORTIZATION OF "IN-LIEU" REFUND OBLIGATION AND RESTORATION OF PV-3 TEMPORARY IMPAIRMENT. The "In-Lieu" refund obligation referenced in Decision No. 57649 (December 6, 1991), as well as in the 1991 Settlement, shall be deemed fully discharged as of the date of Commission approval of this Agreement, unless discharged earlier pursuant to the terms of the l99l Settlement. Likewise, the temporary value impairment of Palo Verde Unit 3 shall be deemed fully restored as of the date of Commission approval of this Agreement, unless restored earlier pursuant to the terms of the 1991 Settlement. G. DECOMMISSIONING. The rates authorized herein expressly include an annual allowance for decommissioning funding for all three Palo Verde Units at the following ACC jurisdictional levels: PV 1 $3,621,000 PV 2 $3,877,000 PV 3 $3,405,000 APS shall fund the amounts specified above through quarterly contributions to the decommissioning trusts. The Commission hereby adopts and approves the decommissioning factors set forth in Attachment C hereto. However, the Commission shall not be bound in any subsequent rate case to adopt the decommissioning funding levels or decommissioning factors adopted and approved herein, but any subsequent change in such levels or factors adopted by the Commission would not be applied retroactively. H. DEPRECIATION. The rates and charges authorized herein include an allowance for depreciation computed at the annual rates and using the methodology indicated in Attachment D hereto. These revised depreciation rates and methodology are hereby expressly approved. The Company's depreciation rates may also be changed from time to time in accordance with the results of depreciation studies performed by or for APS, with such changes to thereafter become effective upon Staff's approval. The Commission shall not be bound in any subsequent rate case to adopt for ratemaking purposes any changes in depreciation rates made pursuant to this provision, but such ratemaking treatment would not be applied retroactively. Any provision of A.A.C. R14-2-102 inconsistent with this paragraph will be expressly waived. I. IMPROVEMENT OF APS' EQUITY RATIO. In Section 2.E of the l99l Settlement, both Staff and the commission supported APS' goal of continuous progress toward a 40% common equity ratio. Staff continues to support that goal. Therefore, in furtherance of that objective, APS shall, upon receipt of a favorable ruling from the Internal Revenue Service, amortize below the line its unamortized investment tax credits ("ITCs") over a five (5) year period beginning with calendar year 1995. All such amortized ITCs shall thereafter be treated as fully restored to the Company's rate base in any future ratemaking proceedings. J. RATE MIGRATION ADJUSTMENT. The rates and charges authorized herein include the effects of any rate migration occurring as a result of the l99l Settlement, and provisions of Section 20 of such l99l Settlement shall be deemed fully satisfied. K. EXPENDITURES ON DEMAND SIDE MANAGEMENT AND RENEWABLE RESOURCES. It is the parties' intent that significant expenditures on both Demand Side Management ("DSM") and renewable resources development shall be made by APS. APS shall increase its commitment and activities in Demand Side Management and renewable resources according to the following schedule: i. APS shall spend at least $30 million over the next three years on AGREEMENT OF SETTLEMENT - APS RATE CASE pre-approved renewable resources and pre-approved DSM projects (including capital and expensed program costs for renewables, DSM program costs, lost net revenues due to DSM, and a reward or incentive for KW deferrals for DSM). If APS fails to spend or commit to spend $18 million on pre-approved renewable resources or pre-approved DSM projects within three years from the effective date of this order, the unspent or uncommitted portion of such $18 million shall be credited to ratepayers through the Energy Efficiency And Solar Energy Fund ("EEASE Fund") as described in the Plan of Administration (Subparagraph iv.). ii. Each year APS shall spend an initial $6 million on pre-approved DSM and renewables projects ("Base DSM/Renewables Amount"). After APS has spent the required $6 million per year, APS shall be entitled to recover up to $12 million per year through the EEASE Fund for pre-approved renewable resource and DSM projects (including capital and expensed program costs for renewables, DSM program costs, lost net revenues due to DSM, and a reward or incentive for KW deferrals for DSM). The amount recoverable through the EEASE Fund excludes the Base DSM/Renewables Amount. iii. A single EEASE Fund surcharge factor shall be applied to all jurisdictional sales (except those on existing special contracts which exclude the surcharge). To equitably distribute DSM and renewables costs, APS shall explore a full range of DSM and renewables programs for all customer classes and propose for pre- approval, where applicable, customer service charges for DSM and renewables in which the participating customer pays APS for some or all of APS' DSM and renewables costs attributable to that customer. iv. APS shall file a revised "Plan of Administration" for the EEASE Fund within thirty (30) days of the effective date of this order and the plan shall be effective upon a Staff determination that the plan is in compliance with the Commission's order adopting this Settlement. The plan shall include a process to account for the Base DSM/Renewables Amount. v. To be eligible to meet the goals and cost recovery mechanism described in Subparagraphs i. and ii., a renewable or DSM program proposed by APS under the terms of the plan of administration described in Subparagraph iv must have been pre-approved by Staff. The parties intend that the pre-approval process be substantially the same as the existing process established for the EEASE Fund. vi. APS shall expend a minimum of $250,000 on a low income DSM pilot program. vii. On or before December 31, 1994, APS shall submit a three-year renewable resource plan for Staff review and comment that includes: a. an aggressive program to identify, install and operate cost-effective applications of renewables within the APS system by the end of the three-year plan period; b. an aggressive program to identify, install and operate cost-effective applications of renewables (which are expected to be cost-effective within a few years) by the end of the three-year plan period; c. a mix of technologies that must include photovoltaics and solar thermal energy systems; d. research and development projects such as resource assessments for and test installations of wind energy systems, geothermal systems, biomass systems, and other innovative renewable technologies; and e. a mix of off-grid applications, grid-connected end use applications, distribution and transmission support, and generation. f. APS shall work cooperatively with Staff to develop the plan. g. APS shall commit to spend at least $9 million on renewables over the next three years as part of its obligation under Subparagraph i. herein. h. Nothing in this Subparagraph vii. shall be construed as obliging APS to exceed the spending levels required by Subparagraph i. viii. APS shall report annually to staff on its renewable resources activities. This report shall include a formal presentation at a workshop and a written report. ix. APS' goal of achieving 12 MW of renewables by December 31, 2000 as stated in the Resource Planning hearing (Docket No. U-0000-93-052) shall not be affected by this Agreement. Expenditures made by APS on pre-approved projects during the next three years for the purpose of achieving this goal are eligible for recovery through the EEASE Fund pursuant to Subparagraphs i. and ii. x. The provisions of this paragraph shall supersede any provisions of the decision in Docket No. U-0000-93-052 to the extent they are inconsistent. L. ADJUSTMENT FOR EFFECTIVE COST CONTAINMENT. In furtherance of the Commission's goal to establish regulatory procedures which encourage superior utility performance, the Company shall have the opportunity to earn a reward in its next general rate proceeding if that rate proceeding results in no increase in residential rates. In that proceeding, the Commission shall compare the costs of service for fuel expense and operation and maintenance, for the test period under review, with the target cost of service index for fuel expense and operation and maintenance for all sales including sales for resale (but excluding interchange and non-traditional sales) of 3.63 cents/kWh to determine if the Company has achieved additional cost savings. Any achieved cost savings that result in a price index below 3.63 cents/kWh for fuel expense and operation and maintenance for all sales including sales for resale (but excluding interchange and non-traditional sales) shall be allocated in such rate proceeding between the Company's customers and its shareholders by first adding to the Company's otherwise appropriate jurisdictional revenue requirement 45% of such savings. M. FUTURE RATE TREATMENT OF PALO VERDE. Based on current Staff analysis of APS' loads and resources, all three Palo Verde generating units are used and useful and are included in rate base, less the net prudence disallowance required by the l99l Settlement. In subsequent rate cases, all three Palo Verde units shall likewise be included in rate base and their fair value shall be based upon the depreciated original cost value and reconstruction values, less the net prudence disallowance adjustment in the l99l Settlement, in the same manner as other APS generating facilities. Notwithstanding the foregoing, in the event that significant changes in the operating characteristics, reliability or efficiency of any or all of the Palo Verde units occur, or any unit is derated, the Commission may re-examine in subsequent APS general rate cases the extent to which such unit continues to be used and useful. N. AFFILIATE TRANSACTION REQUIREMENTS. APS and its affiliates shall remain subject to the provision of A.A.C. R14-2-801, et seq., as modified by Decision No. 58063 (November 3, 1992). However, the additional reporting and prior approval provisions of Commission Decision Nos. 54504 (April 29, 1985) and 55196 (September 18, 1986) are no longer necessary and are hereby expressly revoked. O. POST-RETIREMENT EMPLOYEE BENEFITS. The rates and charges herein do not include an allowance for Post-Retirement Employee Benefits ("OPEBs") as required under SFAS 106. APS, however, is funding OPEBs using external funds. Although the Commission has not permitted recovery of this liability accounting approach for any Arizona regulated entity, Staff will consider recovery of these expenses in future rate proceedings. P. INNOVATIVE RATES FOR "AT RISK" CUSTOMERS. In today's competitive environment, APS and Staff agree that traditional ratemaking based on fully-allocated embedded cost of service may be inappropriate for certain of the company's larger customers. APS faces a significantly larger risk that such customers may decide to leave the APS system for all or part of their electric service needs, thus imposing the responsibility for stranded fixed costs on others. This competitive challenge must be met by timely permitting innovative rate structures and agreements that allow APS maximum flexibility in responding to competition, while at the same time benefiting its remaining customers. Consistent with the above acknowledgements, Staff, therefore, will expeditiously review any APS tariff or contract filing for such customers and recommend that such filings be decided promptly by the Commission. Staff agrees that such tariffs or contracts may contain price adjustment provisions which shall be effective in accordance with their terms, provided that such prices are at or above APS' marginal costs for service to such customers. Q. MISCELLANEOUS RATE CHANGES. This Agreement shall not preclude changes during the Rate Moratorium Period to specific rate schedules or terms and conditions of service, or the approval of new rates or terms or conditions of service, that do not significantly affect the overall earnings of the Company. R. FAIR VALUE. For rate making purposes, and in accordance with the terms of this Agreement, APS' "fair value rate base" is $5,019,405,000 as of September 30, 1993. A fair rate of return on APS' fair value rate base is 7.35%. Staff and APS stipulate to the adoption of the above stated fair value rate base and fair rate of return and agree that the resultant revenue decrease, as reflected in Paragraph A above, results in just and reasonable rates for the Company. The determinations made in this section are made solely for the purpose of the settlement contemplated by this Agreement. S. EFFECTIVE DATE. Each provision of this Agreement is in consideration and support of all the other provisions. This Agreement shall not become effective until the issuance of a final Commission Order approving this Agreement without change or alteration on or before June 1, 1994 in the form of the Proposed Order attached hereto as Attachment E. In the event that the Commission fails to adopt this Agreement according to its terms on or before June 1, 1994, this Agreement shall be deemed automatically withdrawn, the rate reduction provisions of this Agreement shall not take effect, and APS and Staff shall be free to pursue their respective positions without prejudice. In addition, if any appeal is taken or other judicial review is sought of a final Commission order approving this Agreement, then the parties shall no longer be bound by the terms of this Agreement and this Agreement shall automatically become null and void, in which case: (1) the rate reduction specified in Paragraph A. shall immediately cease; (2) all bills rendered on or after that date shall be at the rates existing immediately prior to the Commission's approval of this Agreement; and (3) the revenue reduction theretofore experienced by APS pursuant to Paragraph A. shall be recovered through the EEASE surcharge mechanism. T. AGREEMENT NOT PRECEDENTIAL. The terms and provisions of this Agreement apply solely to and are binding only in the context of the purposes and results of this Agreement and none of the positions taken herein by APS may be referred to, cited or relied upon by any other party in any fashion as precedent or otherwise in any other proceeding before this Commission or any other regulatory agency or before any court of law for any purpose except in furtherance of the purposes and results of this Agreement. Nothing in this Agreement shall be construed as imposing a cap on the Company's otherwise reasonable and prudent cost of service for purposes of setting just and reasonable rates. U. AGREEMENT AND COMPROMISE. This Agreement represents an attempt to compromise and settle disputed claims regarding the prospective just and reasonable rate levels for APS in a manner consistent with the public interest and applicable legal requirements. Nothing contained in this Agreement is an admission by APS that its current rate levels or rate design are unjust or unreasonable. V. PROPOSED FORM OF ORDER. A proposed form of order is appended hereto as Attachment E, and is acceptable to both APS and Staff. DATED at Phoenix, Arizona, this 20th day of April, 1994.

JENNINGS COMMISSIONER DALE H. MORGAN COMMISSIONER IN THE MATTER OF THE COMMISSION'S ) DOCKET NO. U-1345-94-120 EXAMINATION OF THE RATES AND ) CHARGES OF ARIZONA PUBLIC SERVICE ) DECISION NO.__________ COMPANY ) ___________________________________) ORDER Open Meeting May __, 1994 Phoenix, Arizona FINDINGS OF FACT 1. Arizona Public Service Company ("APS") is an Arizona corporation providing electric utility service within the State of Arizona. 2. The rates and charges currently in effect for APS were determined to be just and reasonable in APS' last general rate case, Decision No. 57649, dated December 6, 1991. 3. Since Decision No. 57649, a number of events have occurred which affect APS' expenses, rate base and rate of return. Included among those events are: A. Capital costs for APS have fallen significantly. B. APS has re-financed significant amounts of debt, and has retired old preferred stock and issued new lower-cost preferred stock. C. APS has undertaken several programs to reduce costs and improve efficiency. D. APS has experienced significant growth in kWh sales related to new customers. 4. The Staff of the Commission undertook a preliminary review of these events and their impact on APS. APS provided Staff with substantial amounts of data and supporting documentation, and made personnel available as needed to help explain or interpret the data, to assist Staff in conducting the review. 5. As a result of discussions conducted subsequent to Staff's review, Staff and APS jointly concluded that the rates and charges previously authorized by the Commission for APS should be reduced. Staff and APS also reached agreement on a number of related issues. 6. Staff and APS believe that the agreement they have reached is consistent with the best interests of the parties and the public interest generally. The particulars of the agreement are memorialized in a written Rate Settlement Agreement ("Agreement"), a copy of which is attached hereto as Exhibit 1. 7. Pursuant to the Agreement, Staff and APS have agreed to the following: A. REVENUE REDUCTION. For usage on or after the effective date of the Agreement, as determined in accordance with Paragraph S, APS jurisdictional rates will be decreased by approximately 2.2% (approximately $32.3 million annually, based on September 30, 1993 sales as adjusted). B. SETTLEMENT RATES. The revenue decrease provided for in Paragraph A shall be allocated among customer classes by means of a uniform .20 cents/kWh reduction in the energy charges for all APS rate schedules except those rate schedules set forth in Attachment A to the Agreement. In addition, and concurrent with this rate reduction, APS will be authorized to amend Schedule 1 of its tariffs. These revised tariff sheets are set forth in Attachment B to the Agreement. C. MORATORIUM ON AND PROCEDURES FOR FURTHER RATE CHANGES. i. APS shall not file for a change to its general rates and charges prior to December 31, 1996 ("Rate Moratorium Period"). Staff will likewise be subject to the same moratorium. This moratorium shall not apply to price changes pursuant to Paragraph P. ii. The next general rate application filed by APS will become effective and permanent as soon as practicable after the filing, but in no event later than 12 months after the filing. Such time limit shall not be extended and shall supersede any Commission regulation or legislative enactment which provides for a different period of time, unless the Commission determines that such time limit has become unreasonable due either to any amendment to the rate filing made by APS which substantially alters the amount of the requested rate change or substantially alters the facts used as a basis for the requested rate change, or to an extraordinary event not otherwise provided for. The provisions of this subparagraph shall not apply to any general rate application filed by APS after December 31, 1997. iii. During the six month period following the filing referenced in the preceding subparagraph, APS and Staff will act in good faith to use their best efforts to achieve a settlement on APS' filing and will submit a written report to the Commission at the end of that period on the outcome of such settlement activities. If a settlement is reached, Staff and APS shall promptly file a motion seeking Commission approval of the settlement, and the Commission shall accept or reject the settlement as soon as practicable after filing. iv. Neither APS nor Staff shall be prevented from seeking a change in rates prior to or after December 31, 1996 in the event of conditions or circumstances which constitute an emergency, such as the inability to finance on reasonable terms or material increases in the Company's cost of service as a result of federal, tribal, state or local laws, regulatory requirements or orders. Staff's review of such a request by APS for emergency rates shall focus on the existence of a substantial threat or harm to APS' ability to continue to provide reliable service. D. ESTABLISHMENT OF FUTURE RATE PRINCIPLES. APS will aggressively pursue the cost savings contemplated by Paragraph L with the goal of maintaining average residential prices beyond the Rate Moratorium Period at the proposed 10.45 cents/kWh level resulting from this settlement rate reduction. To meet this goal, APS will have to further reduce operating costs to offset increases in externally imposed expenses, such as interest and other capital costs, fuel and taxes. In addition, APS will require additional regulatory flexibility and pricing freedom to properly respond to the competitive forces and financial risks inherent in the larger customer market segments. Therefore, Staff will meet with APS in a good faith attempt to develop new pricing and operating procedures that are responsive to market conditions, competitive pressures in the electric utility industry, and the Commission's relationship to regulated utilities and their customers. In this endeavor, the parties agree to consider, inter alia, flexible pricing provisions, innovative procedures, and product pricing principles. The parties agree to provide a written report on their progress to the Commission within 12 months of the date of Commission approval of the Agreement and will request prompt Commission approval of recommendations that will assist APS in achieving its residential price stability goals. E. PROPERTY INCLUDED IN RATE BASE. The rates and charges authorized herein fully include a return on the recorded book original cost of all jurisdictional APS assets (net of depreciation, amortization, and deferred income taxes and other deferred credits) as of September 30, 1993, excepting construction work in progress as of such date. However, nothing in the Agreement shall be construed as prohibiting Staff or any other party from pursuing new issues related to expenditures made or actions taken after September 30, 1993. F. AMORTIZATION OF "IN-LIEU" REFUND OBLIGATION AND RESTORATION OF PV-3 TEMPORARY IMPAIRMENT. The "In-Lieu" refund obligation referenced in Decision No. 57649 (December 6, 1991), as well as in the 1991 Settlement, shall be deemed fully discharged as of the date of Commission approval of the Agreement, unless discharged earlier pursuant to the terms of the l99l Settlement. Likewise, the temporary value impairment of Palo Verde Unit 3 shall be deemed fully restored as of the date of Commission approval of the Agreement, unless restored earlier pursuant to the terms of the 1991 Settlement. G. DECOMMISSIONING. The rates authorized herein expressly include an annual allowance for decommissioning funding for all three Palo Verde Units at the following ACC jurisdictional levels: PV 1 $3,621,000 PV 2 $3,877,000 PV 3 $3,405,000 APS shall fund the amounts specified above through quarterly contributions to the decommissioning trusts. The Commission hereby adopts and approves the decommissioning factors set forth in Attachment C to the Agreement. However, the Commission shall not be bound in any subsequent rate case to adopt the decommissioning funding levels or decommissioning factors adopted and approved herein, but any subsequent change in such levels or factors adopted by the Commission would not be applied retroactively. H. DEPRECIATION. The rates and charges authorized herein include an allowance for depreciation computed at the annual rates and using the methodology indicated in Attachment D to the Agreement. These revised depreciation rates and methodology are hereby expressly approved. The Company's depreciation rates may also be changed from time to time in accordance with the results of depreciation studies performed by or for APS, with such changes to thereafter become effective upon Staff's approval. The Commission shall not be bound in any subsequent rate case to adopt for ratemaking purposes any changes in depreciation rates made pursuant to this provision, but such ratemaking treatment would not be applied retroactively. Any provision of A.A.C. R14-2-102 inconsistent with this paragraph will be expressly waived. I. IMPROVEMENT OF APS' EQUITY RATIO. In Section 2.E of the l99l Settlement, both Staff and the commission supported APS' goal of continuous progress toward a 40% common equity ratio. Staff continues to support that goal. Therefore, in furtherance of that objective, APS shall, upon receipt of a favorable ruling from the Internal Revenue Service, amortize below the line its unamortized investment tax credits ("ITCs") over a five (5) year period beginning with calendar year 1995. All such amortized ITCs shall thereafter be treated as fully restored to the Company's rate base in any future ratemaking proceedings. J. RATE MIGRATION ADJUSTMENT. The rates and charges authorized herein include the effects of any rate migration occurring as a result of the l99l Settlement, and provisions of Section 20 of such l99l Settlement shall be deemed fully satisfied. K. EXPENDITURES ON DEMAND SIDE MANAGEMENT AND RENEWABLE RESOURCES. It is the parties' intent that significant expenditures on both Demand Side Management ("DSM") and renewable resources development shall be made by APS. APS shall increase its commitment and activities in Demand Side Management and renewable resources according to the following schedule: i. APS shall spend at least $30 million over the next three years on pre-approved renewable resources and pre-approved DSM projects (including capital and expensed program costs for renewables, DSM program costs, lost net revenues due to DSM, and a reward or incentive for KW deferrals for DSM). If APS fails to spend or commit to spend $18 million on pre-approved renewable resources or pre-approved DSM projects within three years from the effective date of this order, the unspent or uncommitted portion of such $18 million shall be credited to ratepayers through the Energy Efficiency And Solar Energy Fund ("EEASE Fund") as de- scribed in the Plan of Administration (Subparagraph iv.). ii. Each year APS shall spend an initial $6 million on pre-approved DSM and renewables projects ("Base DSM/Renewables Amount"). After APS has spent the required $6 million per year, APS shall be entitled to recover up to $12 million per year through the EEASE Fund for pre-approved renewable resource and DSM projects (including capital and expensed program costs for renewables, DSM program costs, lost net revenues due to DSM, and a reward or incentive for KW deferrals for DSM). The amount recoverable through the EEASE Fund excludes the Base DSM/Renewables Amount. iii. A single EEASE Fund surcharge factor shall be applied to all jurisdictional sales (except those on existing special contracts which exclude the surcharge). To equitably distribute DSM and renewables costs, APS shall explore a full range of DSM and renewables programs for all customer classes and propose for pre-approval, where applicable, customer service charges for DSM and renewables in which the participating customer pays APS for some or all of APS' DSM and renewables costs attributable to that customer. iv. APS shall file a revised "Plan of Administration" for the EEASE Fund within thirty (30) days of the effective date of this order and the plan shall be effective upon a Staff determination that the plan is in compliance with the Commission's order adopting the Settlement. The plan shall include a process to account for the Base DSM/Renewables Amount. v. To be eligible to meet the goals and cost recovery mechanism described in Subparagraphs i. and ii., a renewable or DSM program proposed by APS under the terms of the plan of administration described in Subparagraph iv must have been pre-approved by Staff. The parties intend that the pre-approval process be substantially the same as the existing process established for the EEASE Fund. vi. APS shall expend a minimum of $250,000 on a low income DSM pilot program. vii. On or before December 31, 1994, APS shall submit a three-year renewable resource plan for Staff review and comment that includes: a. an aggressive program to identify, install and operate cost-effective applications of renewables within the APS system by the end of the three-year plan period; b. an aggressive program to identify, install and operate cost-effective applications of renewables (which are expected to be cost-effective within a few years) by the end of the three-year plan period; c. a mix of technologies that must include photovoltaics and solar thermal energy systems; d. research and development projects such as resource assessments for and test installations of wind energy systems, geothermal systems, biomass systems, and other innovative renewable technologies; and e. a mix of off-grid applications, grid-connected end use applications, distribution and transmission support, and generation. f. APS shall work cooperatively with Staff to develop the plan. g. APS shall commit to spend at least $9 million on renewables over the next three years as part of its obligation under Subparagraph i. herein. h. Nothing in this Subparagraph vii. shall be construed as obliging APS to exceed the spending levels required by Subparagraph i. viii. APS shall report annually to staff on its renewable resources activities. This report shall include a formal presentation at a workshop and a written report. ix. APS' goal of achieving 12 MW of renewables by December 31, 2000 as stated in the Resource Planning hearing (Docket No. U-0000-93-052) shall not be affected by the Agreement. Expenditures made by APS on pre-approved projects during the next three years for the purpose of achieving this goal are eligible for recovery through the EEASE Fund pursuant to Subparagraphs i. and ii. x. The provisions of this paragraph shall supersede any provisions of the decision in Docket No. U-0000-93-052 to the extent they are inconsistent. L. ADJUSTMENT FOR EFFECTIVE COST CONTAINMENT. In furtherance of the Commission's goal to establish regulatory procedures which encourage superior utility performance, the Company shall have the opportunity to earn a reward in its next general rate proceeding if that rate proceeding results in no increase in residen- tial rates. In that proceeding, the Commission shall compare the costs of service for fuel expense and operation and maintenance, for the test period under review, with the target cost of service index for fuel expense and operation and maintenance for all sales including sales for resale (but excluding interchange and non-traditional sales) of 3.63 cents/kWh to determine if the Company has achieved additional cost savings. Any achieved cost savings that result in a price index below 3.63 cents/kWh for fuel expense and operation and maintenance for all sales including sales for resale (but excluding interchange and non-traditional sales) shall be allocated in such rate proceeding between the Company's customers and its shareholders by first adding to the Company's otherwise appropriate jurisdictional revenue requirement 45% of such savings. M. FUTURE RATE TREATMENT OF PALO VERDE. Based on current Staff analysis of APS' loads and resources, all three Palo Verde generating units are used and useful and are included in rate base, less the net prudence disallowance required by the l99l Settlement. In subsequent rate cases, all three Palo Verde units shall likewise be included in rate base and their fair value shall be based upon the depreciated original cost value and reconstruction values, less the net prudence disallowance adjustment in the l99l Settlement, in the same manner as other APS generating facilities. Notwithstanding the foregoing, in the event that significant changes in the operating characteristics, reliability or efficiency of any or all of the Palo Verde units occur, or any unit is derated, the Commission may re-examine in subsequent APS general rate cases the extent to which such unit continues to be used and useful. N. AFFILIATE TRANSACTION REQUIREMENTS. APS and its affiliates shall remain subject to the provision of A.A.C. R14-2-801, et seq., as modified by Decision No. 58063 (November 3, 1992). However, the additional reporting and prior approval provisions of Commission Decision Nos. 54504 (April 29, 1985) and 55196 (September 18, 1986) are no longer necessary and are hereby expressly revoked. O. POST-RETIREMENT EMPLOYEE BENEFITS. The rates and charges herein do not include an allowance for Post-Retirement Employee Benefits ("OPEBs") as required under SFAS 106. APS, however, is funding OPEBs using external funds. Although the Commission has not permitted recovery of this liability accounting approach for any Arizona regulated entity, Staff will consider recovery of these expenses in future rate proceedings. P. INNOVATIVE RATES FOR "AT RISK" CUSTOMERS. In today's competitive environment, APS and Staff agree that traditional ratemaking based on fully-allocated embedded cost of service may be inappropriate for certain of the company's larger customers. APS faces a significantly larger risk that such customers may decide to leave the APS system for all or part of their electric service needs, thus imposing the responsibility for stranded fixed costs on others. This competitive challenge must be met by timely permitting innovative rate structures and agreements that allow APS maximum flexibility in responding to competition, while at the same time benefiting its remaining customers. Consistent with the above acknowledgements, Staff, therefore, will expeditiously review any APS tariff or contract filing for such customers and recommend that such filings be decided promptly by the Commission. Staff agrees that such tariffs or contracts may contain price adjustment provisions which shall be effective in accordance with their terms, provided that such prices are at or above APS' marginal costs for service to such customers. Q. MISCELLANEOUS RATE CHANGES. The Agreement shall not preclude changes during the Rate Moratorium Period to specific rate schedules or terms and conditions of service, or the approval of new rates or terms or conditions of service, that do not significantly affect the overall earnings of the Company. R. FAIR VALUE. For rate making purposes, and in accordance with the terms of the Agreement, APS' "fair value rate base" is $5,019,405,000 as of September 30, 1993. A fair rate of return on APS' fair value rate base is 7.35%. Staff and APS stipulate to the adoption of the above stated fair value rate base and fair rate of return and agree that the resultant revenue decrease, as reflected in Paragraph A above, results in just and reasonable rates for the Company. The determinations made in this section are made solely for the purpose of the settlement contemplated by the Agreement. S. EFFECTIVE DATE. Each provision of the Agreement is in consideration and support of all the other provisions. The Agreement shall not become effective until the issuance of a final Commission Order approving the Agreement without change or alteration on or before June 1, 1994 in the form of the Proposed Order attached thereto as Attachment E. In the event that the Commission fails to adopt the Agreement according to its terms on or before June 1, 1994, the Agreement shall be deemed automatically withdrawn, the rate reduction provisions of the Agreement shall not take effect, and APS and Staff shall be free to pursue their respective positions without prejudice. In addition, if any appeal is taken or other judicial review is sought of a final Commission order approving the Agreement, then the parties shall no longer be bound by the terms of the Agreement and the Agreement shall automatically become null and void, in which case: (1) the rate reduction specified in paragraph A. shall immediately cease; (2) all bills rendered on or after that date shall be at the rates existing immediately prior to the Commission's approval of the Agreement; and (3) the revenue reduction theretofore experienced by APS pursuant to paragraph A. shall be recovered through the EEASE surcharge mechanism. T. AGREEMENT NOT PRECEDENTIAL. The terms and provisions of the Agreement apply solely to and are binding only in the context of the purposes and results of the Agreement and none of the positions taken herein by APS may be referred to, cited or relied upon by any other party in any fashion as precedent or otherwise in any other proceeding before this Commission or any other regulatory agency or before any court of law for any purpose except in furtherance of the purposes and results of this Agreement. Nothing in this Agreement shall be construed as imposing a cap on the Company's otherwise reasonable and prudent cost of service for purposes of setting just and reasonable rates. U. AGREEMENT AND COMPROMISE. The Agreement represents an attempt to compromise and settle disputed claims regarding the prospective just and reasonable rate levels for APS in a manner consistent with the public interest and applicable legal requirements. Nothing contained in the Agreement is an admission by APS that its current rate levels or rate design are unjust or unreasonable. CONCLUSIONS OF LAW 1. APS is a public service corporation within the meaning of Article 15 of the Arizona Constitution and A.R.S. Section 40-250, 40-251 and 40-367. 2. The Commission has jurisdiction over APS, over the subject matter of this proceeding, and over the Agreement submitted by the Staff and APS. 3. The Agreement resolves all matters contained therein in a manner which is just and reasonable, and which promotes the public interest. 4. The Commission's acceptance and approval of the terms of this Agreement between Staff and APS are in the public interest. 5. Based on the Agreement of APS and Staff, for purposes of this proceeding, APS' fair value rate base as of September 30, 1993 is $5,019,405,000, and a fair and reasonable rate of return on that fair value rate base is 7.35%. 6. Based on the Agreement between APS and Staff, it is appropriate to reduce APS' authorized revenues by $32.3 million from September 30, 1993 sales as adjusted. 7. APS should be directed to file revised tariffs consistent with the Agreement and the findings contained herein. 8. The rates and charges authorized herein are just and reasonable. ORDER IT IS THEREFORE ORDERED that APS shall decrease its rates and charges for all usage on or after the effective date of this Order consistent with the Findings of Fact and Conclusions of Law contained herein so as to result in an annual decrease of $32.3 million, and shall fund $6 million per year for the next three years on pre-approved Demand Side Management and renewables projects, for a total of $38.3 million per year in benefits to APS' customers. IT IS FURTHER ORDERED that this Order incorporates the Agreement executed April 20, 1994, between APS and Staff, and such Order is expressly conditioned thereon. IT IS FURTHER ORDERED that the terms and conditions of the Agreement be and the same are hereby adopted and approved. IT IS FURTHER ORDERED that APS is authorized and directed to file revised schedules of rates and charges consistent with the Findings and Conclusions of this Order. IT IS FURTHER ORDERED that neither APS nor Commission Staff shall file any application to initiate a general rate change prior to December 31, 1996. IT IS FURTHER ORDERED that any general rate change proposed by the Company on or after December 31, 1996, but not later than December 31, 1997, if substantiated after appropriate notice and hearing and authorized by the Commission, will become effective within twelve months following the filing of the proposed rate change. IT IS FURTHER ORDERED that this Order shall become effective immediately.
