AVU-E-12-08 CASE NO. AVtJ-G-12-07 DIRECT TESTIMONY OF KELLY 0. NORWOOD IN SUPPORT OF THE STIPULATION AND SETTLEMENT FOR AVISTA CORPORATION (ELECTRIC AND NATURAL GAS) I I. INTRODUCTION 2 Q. Please state your name, employer and business 3 address. 4 A. My name is Kelly 0. Norwood and I am employed as 5 the Vice-President of State and Federal Regulation for 6 Avista Utilities ("Company" or "Avista"), at 1411 East 7 Mission Avenue, Spokane, Washington. 8 Q. Would you briefly describe your educational background and professional experience? 10 A. Yes. I am a graduate of Eastern Washington 11 University with a Bachelor of Arts Degree in Business 12 Administration, majoring in Accounting. I joined the 13 Company in June of 1981. Over the past 31 years, I have 14 spent approximately 20 years in the Rates Department with 15 involvement in cost of service, rate design, revenue 16 requirements and other aspects of ratemaking. I spent 17 approximately 11 years in the Energy Resources Department 18 (power supply and natural gas supply) in a variety of roles, 19 with involvement in resource planning, system operations, 20 resource analysis, negotiation of power contracts, and risk 21 management. I was appointed Vice-President of State & 22 Federal Regulation in March 2002. Norwood, Di Avista Corporation I Q. What is the scope of your pre-filed testimony in 2 this proceeding? 3 A. The purpose of my testimony is to describe and 4 support the Stipulation and Settlement ("Stipulation"), 5 filed on February 6, 2013 between the Staff of the Idaho 6 Public Utilities Commission ("Staff'), Clearwater Paper 7 Corporation ("Clearwater"), Idaho Forest Group, LLC ("Idaho 8 Forest"), the Idaho Conservation League ("Conservation 9 League"), and the Company, which, if approved by the 10 Commission, would resolve all of the issues in the Company's 11 filing. These entities are collectively referred to as the 12 "Parties," and represent several parties in the above- 13 referenced cases.' 14 The Stipulation is the product of settlement 15 discussions held in the Commission offices on January 17 and 16 24, 2013. The Stipulation between the Parties resolved all 17 issues associated with the calculation of the Company's 18 requested cost of capital, including capital structure and The Community Action Partnership Association of Idaho ("CAPAI") participated in settlement discussions and is continuing to review its position with regard to the Stipulation, as proposed, and will be filing separate comments and/or testimony in that regard. The Snake River Alliance, as an intervenor, was provided notice of the settlement discussions, but did not participate. However, on February 20, 2013, The Snake River Alliance, through separate communication filed notice with the Commission indicating that, although not a signatory to the Settlement agreement, they do support the Stipulation agreed to by the Parties. Norwood, Di 2 Avista Corporation cost components, and resolved all revenue requirement, rate spread and rate design issues. The Stipulation represents a compromise among differing points of view. Concessions were made by all Parties to reach a balancing of interests. As will be explained in the following testimony, the Stipulation represents a fair, just and reasonable compromise of the issues and is in the public interest. Q. Are you sponsoring any exhibits? A. Yes. I am sponsoring Exhibit No. 1, which is a copy of the Stipulation and Settlement filed on February 6, 2013, with the Commission. Q. Please explain how the Parties arrived at the Stipulation in this proceeding. A. The Stipulation is the end result of extensive audit work conducted through the discovery process 2 , including a week-long on-site audit by Commission Staff, and hard bargaining by all Parties in this proceeding. I would like to express my appreciation to all Parties involved in this proceeding for their efforts in arriving at this Stipulation and to this Commission for your For its part, Avista responded to over 270 production requests (including sub-parts) from iptic Staff and other intervening parties. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Norwood, Di 3 Avista Corporation 1 willingness to hear this matter promptly, in light of the 2 proposed April 1 effective date. 3 Q. Why is the Stipulation in the public interest? 4 A. The Stipulation is in the "public interest" for 5 several reasons, which include: 6 • It was the product of the give-and-take of 7 negotiation that produced an "end result" that is 8 just and reasonable. 9 • It is supported by the evidence, demonstrating the 10 need for rate adjustments to provide recovery of 11 necessary expenditures and investment, the costs of 12 which are not offset by a growth in sales margins. 13 • The Settlement enjoys broad-based support from a 14 variety of constituencies, including Clearwater, 15 Idaho Forest, the Conservation League, and the Snake 16 River Alliance, serving to address their specific 17 needs, and the Staff of the Commission representing 18 all customers. 19 • The Settlement provides base rate certainty over 20 the next two years (2013/2014), which would benefit 21 all customers, as they plan and budget for their 22 needs. 23 • It would prohibit Avista from making further 24 changes in base rates prior to January 1, 2015, 25 thereby breaking the yearly cycle of rate filings. 26 • The impact of the base rate increases in Step 2, 27 effective October 1, 2013, would be mitigated, in 28 part, by the amortization of the BPA settlement 29 payment for electric and the PGA deferral credit 30 balance for natural gas. 31 • The "stay-out" provision preventing a further 32 change in base rates until 2015 would challenge 33 Avista to manage its costs in order to have the 34 opportunity to earn the agreed-upon return on equity; 35 indeed, the Company has already put in place cost 36 saving measures, such as the voluntary severance 37 program reducing Avista's work force by 55 38 individuals, executed at year-end 2012. 39 • Finally, as I will discuss later in my testimony, 40 in order to allay any concerns that Avista might 41 somehow "over-earn" during the 2013/2014 rate- Norwood, Di 4 Avista Corporation I effective period, Avista would agree to refund back 2 to customers 50% of any earnings that exceed the 9.8% 3 agreed-upon ROE during the 2013 and 2014 rate- 4 effective periods, based on actual, consolidated 5 results for its Idaho electric and natural gas 6 operations. 7 8 Q. Would you briefly summarize the Stipulation? 9 A. Yes. Under the terms of the Stipulation, Avista 10 would implement revised tariff schedules designed to recover 11 additional annual electric and natural gas revenue in two 12 steps, effective April 1 and October 1, 2013. This 13 represents a two-year rate plan for the period 2013 and 14 2014, designed to provide retail revenues necessary to allow 15 the Company the opportunity to earn the return agreed to in 16 the Stipulation. 17 For electric operations, there is no electric base rate 18 increase in the first step (April 1, 2013), however, 19 effective October 1, 2013 (Step 2), the Parties agree to an 20 overall base rate increase of 3.1% (3.2% on a billed basis) 21 or $7.825 million in electric annual base tariff revenues. 22 Partially offsetting the October 1, 2013 electric increase 23 is $3.865 million of revenues resulting from a payment to be 24 made to Avista by the Bonneville Power Administration 25 (EPA)3 . This payment to Avista is for the Parallel Operation The agreement between Avista and BPA was approved by FERC on February 5, 2013. Norwood, Di 5 Avista Corporation 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Settlement agreement, pertaining to BPA's prior use of Avista's transmission 'system (discussed later in my testimony), and amortized over 15 months, from October 1, 2013 to December 31, 2014, resulting in a decrease to billed customer rates of 1.3. As a result of the two October 1, 2013 adjustments, the overall net increase on a billed basis is l.9'. A residential customer using an average of 930 kilowatt hours per month would see a $2.04, or 2.6s, increase per month for a revised monthly bill of $80.73. (See Exhibit No. 1, Paragraph 21, for the October 1, 2013 percentage change in rates by rate schedule.) The table below summarizes the April 1 and October 1, 2013 electric rate changes: Summary of Electric Rate Changes (millions) Revenue Base Rate Billing Rate Net Billing Requirement Change Change Ofiet Rate Change April 1, 2013 $0.00 0.0% 0.0% 0.0% 0.0% October 1, 2013 $7.825 3.1% 3.2% -1.3% 1.9% For natural gas, under Step 1, effective April 1, 2013, Avista would implement revised tariff schedules designed to recover $3.115 million in additional annual natural gas revenue, representing an overall 4.9 (5.0 on a billed basis) increase. As a result of the April 1, 2013 rate adjustment, a residential customer using an average of 60 Norwood, Di 6 Avista Corporation 1 therms per month would see a $2.82, or 5.4%, increase per 2 month for a revised monthly bill of $55.37. 3 Under step 2, effective October 1, 2013, Avista would 4 implement revised tariff schedules designed to recover an 5 additional $1.330 million in annual natural gas revenue, 6 representing an overall 2.0% increase (on both a base and 7 billed basis). Partially offsetting the natural gas rate 8 increase would be a $1.550 million Purchase Gas Adjustment 9 (PGA) deferral credit balance from the 2012 PGA. This 10 credit would be amortized over 15 months, October 1, 2013 to 11 December 31, 2014, resulting in a decrease to billed 12 customer rates of 1.7%. The result of the two October 1, 13 2013 adjustments is an overall net increase on a billed 14 basis of 0.3%. A residential customer using an average of 15 60 therms per month would see a $0.31, or 0.6%, increase per 16 month for a revised monthly bill of $55.68. Other customer 17 classes, except transportation customers, would see an 18 overall net rate decrease October 1, 2013. (See Exhibit No. 19 1, Paragraph 22, for the April 1 and October 1, 2013 change 20 in rates by rate schedule.) 21 Norwood, Di 7 Avista Corporation 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 The table below summarizes the April 1 and October 1, 2013 proposed natural gas rate changes: Summary of Natural Gas Rate Changes (millions) Revenue Base Rate Billing Rate Net Billing Requirement Change Change Oflet Rate Change April 1, 2013 $3.115 4.9% 5.0% 0.0% 5.0% October 1, 2013 $1.330 2.0% 2.0% -1.7% 0.3% Avista would not file another electric or natural gas general rate case before May 31, 2014, and while it may request an effective date earlier than January 1, 2015, final approved new rates would not go into effect prior to January 1, 2015. This does not apply to tariff filings authorized by or contemplated by the terms of the Power Cost Adjustment (PCA), or the Purchased Gas Adjustment tariff (PGA), or other miscellaneous filings. In determining these revenue increases, the Parties have agreed to various adjustments to the Company's original filing, which are summarized in the Stipulation, and described further below. The Stipulation calls for an overall rate of return of 7.91%, determined using a capital structure consisting of 50% common stock equity and 50% long-term debt, an authorized return on equity of 9.8% and cost of debt of 6.01%. Norwood, Di 8 Avista Corporation 1 II. HISTORY OF FILING 2 Q. Please describe the Company's general rate case 3 request, as filed. 4 A. On October 11, 2012, Avista filed an Application 5 with the Commission for authority to increase revenue from 6 electric and natural gas service in Idaho by 4.6 and 7.2'6, 7 respectively. If approved, the Company's revenues for 8 electric base retail rates would have increased by $11.4 9 million annually; Company revenues for natural gas service 10 would have increased by $4.6 million annually. The Company 11 requested an effective date of April 1, 2013 for its 12 proposed electric and natural gas rate increases. By Order 13 No. 32689, dated December 4, 2012, the Commission suspended 14 the proposed schedules of rates and charges for electric and 15 natural gas service. 16 The Company proposed utilizing the results of its 17 electric and natural gas service studies, sponsored by 18 Company witness Knox, as a guide to spread the overall 19 requested electric and natural gas revenue increases by rate 20 schedule on a basis which: 1) moved the rates for nearly all 21 the schedules closer to the cost of providing service, and 22 2) resulted in a reasonable range in the (net) proposed 23 percentage increase across the schedules. The spread of the 24 proposed electric increase generally resulted in the rates Norwood, Di 9 Avista Corporation I of return for the various electric service schedules moving 2 approximately 15% closer to the overall rate of return 3 (unity); whereas the proposed increases for the various 4 natural gas service schedules would move the return 5 approximately 25% closer to the overall rate of return 6 (unity). The Company did not request a change in its 7 electric or natural gas residential basic charges. 8 Q. What are the primary factors driving the Company's 9 need for electric and natural gas increases? 10 A. Approximately 70% of the Company's electric 11 revenue requirement, and 48% for natural gas, is due to an 12 increase in net plant investment (including return on 13 investment, depreciation and taxes, and offset by the tax 14 benefit of interest). 15 The remaining revenue requirement request is due to 16 increases in distribution, operation and maintenance (O&M), 17 and administrative and general (A&G) expenses for both 18 electric and natural gas operations. However, the increased 19 costs for electric operations are partially offset by a 20 reduction in net power supply and transmission expenditures. 21 Norwood, Di 10 Avista Corporation 1 III. REVENUE REQUIREMENT ELEMENTS OF THE STIPULATION 2 Q. Please explain the derivation of the Electric and 3 Natural Gas Revenue Requirements outlined in the 4 Stipulation. 5 A. The Parties agreed that Avista would implement 6 revised tariff schedules designed to recover additional 7 annual electric and natural gas revenue in two steps, 8 effective April 1 and October 1, 2013. This represents a 9 two-year rate plan designed to provide sufficient retail 10 revenues for the period 2013 and 2014, which together with 11 management of costs, would provide the Company with the 12 opportunity to earn the return agreed to in the Stipulation. 13 While Avista's filing requested an electric revenue 14 requirement increase of $11.393 million effective April 1, 15 2013, agreed-upon adjustments, including the agreed-upon 16 rate of return, result in a recommended electric revenue 17 requirement increase of $0.0 as of April 1, 2013 and $7.825 18 million as of October 1, 2013. 19 Similarly, while the Company requested a natural gas 20 revenue requirement increase of $4.561 million effective 21 April 1, 2013, agreed-upon adjustments result in a 22 recommended natural gas revenue requirement increase of 23 $3.115 million as of April 1, 2013 and $1.330 million as of 24 October 1, 2013. Norwood, Di 11 Avista Corporation I Q. Please explain the Parties' agreement with regard 2 to an Authorized Rate of Return, including the Return on 3 Equity. 4 A. The Parties have agreed to a revenue requirement 5 which produces an overall rate of return of 7.91%, based on 6 a return on equity of 9.8%, an equity component at 50% and 7 cost of debt of 6.01%. By comparison, the Company's 8 original filing requested an overall rate of return of 9 8.46%, a return on equity of 10.9%, an equity component of 10 50% and cost of debt of 6.02%. 11 Q. What is the proposed effective date of new rates 12 from the Stipulation? 13 A. The Parties have requested implementation of new 14 retail rates from the Stipulation on April 1, 2013, with 15 further tariff changes on October 1, 2013. These proposed 16 effective dates are an integral part of the Stipulation that 17 includes a negotiated resolution of all of the issues. 18 Q. Please provide an overview of the revenue 19 requirement adjustments agreed to by the Parties resulting 20 in the April 1 and October 1, 2013 revenue requirements. 21 A. A number of the adjustments, agreed to by the 22 Parties, resulted in delaying recovery of 2013 increased 23 costs until October 1, 2013, as well as reducing certain Norwood, Di 12 Avista Corporation expenditures to the agreed-upon levels by the Parties. The Parties agreed to revenue requirements that reflect the adjustments shown below in the excerpted tables from the Stipulation: Table 1: April 1, 2013 Electric Revenue Requirement SUMMARY TABLE OF ADJUSTMENTS TO ELECTRIC REVENUE REQUIREMENT EFFECTIVE APRIL 1, 2013 000s of Dollars Revenue Requirement Rate Base Amount as Filed: $ 11,393 $ 639,030 Adjustments: a.)

Non-Exec Labor $ 215 Adjusted Amounts Effective October 1, 2013 $1,330 $116,070 As can be seen by a quick review of the individual line descriptions provided within the summary tables excerpted from the Stipulation, the adjustments accepted for settlement purposes cover a broad range of revenue and cost categories, including the authorized rate of return. The individual adjustments should not be viewed in isolation; rather, they should be viewed in total as part of the entire Stipulation, and are the result of hard bargaining and compromise. Q. Would you please elaborate on the individual line items contained within the excerpted tables? A. Yes. A description of these adjustments resulting in the Step 1 revenue requirement, effective April 1, 2013 and the Step 2 revenue requirement, effective October 1, 2013, follows. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Norwood, Di 15 Avista Corporation I Step 1: April 1, 2013 Rate. Change: Electric $0.0; Natural 2 Gas $3.115 million: 3 4 Remove 2013 Capital additions - (Table 1, Line b. and 5 Table 3, Line b.) The 2013 electric and natural gas capital 6 additions adjustments, as proposed by the Company in its 7 original filings, were removed, delaying recovery of the 8 associated revenue requirement until the October 1, 2013 9 rate increase. April 1, 2013, therefore, reflected total 10 depreciation expenses and rate base, net of accumulated 11 depreciation and accumulated deferred income tax, as of 12 year-end December 31, 2012. 13 Remove 2013 Expenses - (Table 1, Line c. and Table 3, 14 Line c.) The following adjustments remove 2013 expenses pro 15 formed in the Company's original filing, delaying recovery 16 of those expenditures until the October 1, 2013 rate change: 17 Major Generation O&M - (Table 1, Line c.i.) 2013 18 incremental non-labor generation plant operation and 19 maintenance (O&M) expenses related to the Company's 20 thermal generation plant at Kettle Falls, and its 21 hydro generation plants (electric only). 22 Information Services & Technology - (Table 1, 23 Line c.ii. and Table 3, Line c.i.) 2013 incremental 24 information service and technology expenses, related 25 to the Company's replacement of the Company's Customer Norwood, Di 16 Avista Corporation 1 Service Information System, and increased costs to 2 support various business processes, application 3 support, additional security requirements, annual 4 contractual agreements and maintenance and license 5 fees. 6 CS2 Levelized Return - (Table 1, Line c.iii..) 7 2013 incremental amortization of the deferred 8 levelized return related to the 10-year deferral of 9 return on the Coyote Springs 2 (CS2) 10 investment (electric only). 11 Non-Exec Labor - (Table 1, Line c.iv. and Table 12 3, Line c.ii.) 2013 incremental non-executive labor 13 increases, includes increases approved by the Board of 14 Directors for 2013 for its non-union, non-executive 15 employees, as well as the 2013 union contract 16 increases for union employees. 17 Remove 2013 Property Tax Expense - (Table 1, Line d. 18 and Table 3, Line d.) This adjustment removes the 2013 19 incremental pro forma property tax expense. In its original 20 filing, the Company adjusted test period accrued property 21 tax expense to the expected 2013 rate period expense level 22 based on property values as of December 31, 2012. This 23 adjustment reduces recovery of property tax to 2012 expense 24 levels. Norwood, Di 17 Avista Corporation I Remove Officer Incentive and CPI Escalation - (Table 1, 2 Line e. and Table 3, Line e.) This adjustment removes the 3 officer portion of the employee incentive expense included 4 in the Company's original filing. Included in the Company's 5 original filing was a six-year average (2006-2011) of actual 6 incentive expense adjusted by the Consumer Price Index 7 (CPI). This adjustment in the Settlement also removes the 8 CPI escalation. 9 Miscellaneous Adjustments - (Table 1, Line h. and Table 10 3, Line f.) The Company adopted, for settlement purposes, 11 Staff's proposal to adjust or remove various administrative 12 and general (A&G) and O&M-related costs, including a two- 13 year amortization of Booz & Co. consulting fees, thereby 14 reducing test period expenses, as well as removal of certain 15 other amounts related to OASIS training, abandoned 16 projects, injuries and damages (natural gas only) and 17 depreciation study expenses. 18 Reardan Wind Site - (Table 1, Line f.) In May 2008, 19 Avista purchased the Reardan Wind Project Site from Energy 20 Northwest after it was demonstrated as the Company's least- 21 cost option for securing a renewable resource for its 22 customers, consistent with its 2007 Integrated Resource " Open Access Same-Time Information System (OASIS). Norwood, Di 18 Avista Corporation 1 Plan. Avista later chose to delay the construction of the 2 Reardan project and take advantage of much-lower costs for 3 wind projects that emerged in 2011 (Palouse Wind). Avista 4 recorded $4.0 million of site acquisition and preparation 5 costs, of which approximately $1.7 million is Idaho's share. 6 This includes approximately $0.4 million in AFUDC in 7 accordance with Order No. 30611 (Case No. AVtJ-E-08-04). As 8 a part of the agreed-upon Settlement, Avista would amortize 9 Idaho's portion of the Reardan Wind Project deferred balance 10 of approximately $1.7 million over a two-year period 11 beginning April 1, 2013. 12 Palouse Wind - (Table 1, Line g.) The Parties agree 13 that recovery of costs related to the Palouse Wind Power 14 Purchase Agreement ("PPA") would be included in the PCA, 15 subject to the current sharing (90% customer, 10% Company) 16 until it is included in base rates as part of the 17 implementation of new rates from the Company's next general 18 rate case, anticipated in 2015. This adjustment removes the 19 Palouse Wind PPA expenses from the pro forma power supply 20 adjustment included in the Company's original filing. 21 Q. Please summarize the impact of these adjustments 22 on Step 1, effective April 1, 2013. 23 A. Consolidation of the adjustments discussed above Norwood, Di 19 Avista Corporation 1 for the Step 1 base rate change, effective April 1, 2013, 2 reduces Avista's electric revenue requirement request of 3 $11.393 million to $0.0, and its natural gas revenue 4 requirement request of $4.561 million to $3.115 million, 5 resulting in a 0.0 electric and 3.1 natural gas base rate 6 increase. Net rate base for electric and natural gas is 7 $637.45 million and $112.24 million, respectively, effective 8 April 1, 2013. 9 Q. Please continue your explanation of the revenue [[I] requirement adjustments agreed to by the Parties resulting 11 in the electric and natural gas Step 2, October 1, 2013, 12 rate changes. 13 A. As discussed above, a number of capital and 14 expense related adjustments proposed in the Company's 15 original filing were removed from the electric and natural 16 gas revenue requirements for purposes of the Step 1, rate 17 changes effective April 1, 2013, delaying the recovery of 18 those incremental 2013 increased costs to the Step 2, 19 October 1, 2013 rate changes. A description of these 20 adjustments resulting in the Step 2 increases, effective 21 October 1, 2013, follows. 22 Norwood, Di 20 Avista Corporation I Step 2: October 1, 2013 Rate Changes: Electric $7.825 2 million; Natural Gas $1.330 million: 3 2013 Capital additions - (Table 2, Line a. and Table 4, 4 Line a.) This adjustment includes 2013 capital additions, 5 reflecting total depreciation expense and rate base, net of 6 accumulated depreciation and accumulated deferred income 7 tax, as of year-end December 31, 2013 for electric 8 operations, and an agreed-upon level of rate base for 9 natural gas operations. 10 2013 Expenses - (Table 2, Line c. and Table 4, Line b.) 11 The following adjustments include the 2013 expenses removed 12 from the Step 1 increases, effective April 1, 2013, 13 described above, for recovery in Step 2, effective October 14 1, 2013: 15 Major Generation O&M - (Table 2, Line c.i.) 2013 16 incremental non-labor generation plant operation and 17 maintenance (O&M) expenses (electric only). 18 Information Services & Technology - (Table 2, Line 19 c.ii. and Table 4, Line b.i.) 2013 incremental 20 information service and technology expenses. 21 C52 Levelized Return - (Table 2, Line c.iii.) 22 2013 incremental amortization of the CS2 deferred 23 levelized return (electric only). Norwood, Di 21 Avista Corporation 1 Non-Exec Labor - (Table 2, Line c.iv. and Table 4, 2 Line b.ii.) 2013 incremental non-executive labor 3 increases. 4 2014 Capital additions - (Table 2, Line b.) This 5 adjustment includes certain 2014 capital additions, 6 including depreciation expense and rate base, net of 7 accumulated depreciation and accumulated deferred income 8 tax, to represent an agreed-upon level of rate base 9 (electric only). 10 Amortization of 2013 Coyote Springs 2/Colstrip 11 Maintenance Deferral - Per Order No. 32371 in Case No. AVtJ- 12 E-ll-Ol, in order to address the large variability in year- 13 to-year O&M costs, beginning in 2011, the Company was 14 allowed to defer changes in O&M costs related to its Coyote 15 Springs 2 (CS2) natural gas-fired generating plant located 16 near Boardman, Oregon, and its fifteen (15) percent 17 ownership share of the Colstrip 3 & 4 coal-fired generating 18 plants located in southeastern Montana. The Company 19 compares actual, non-fuel, O&M expenses for the Coyote 20 Springs 2 and Colstrip 3 & 4 plants in the applicable 21 deferral year with the amount of expenses authorized for 22 recovery in base rates, and defers the difference from that 23 currently authorized. The deferral occurs annually, with no 24 carrying charge, with deferred costs being amortized over a Norwood, Di 22 Avista Corporation 1 three-year period, beginning in January of the year 2 following the period costs are deferred. 3 As a part of this Settlement agreement, the Parties 4 agree that the amount deferred in 2013 related to the 5 Company's O&M costs of its CS2 and Colstrip 3 & 4 generating 6 plants would be amortized over three years, beginning with 7 the implementation of new base rates resulting from the 8 Company's next general rate case filing, anticipated in 9 2015. 10 Q. Please summarize the impact of these adjustments 11 on the Step 2 rate adjustments, effective October 1, 2013. 12 A. Consolidation of the adjustments discussed above 13 for the Step 2 base rate changes, effective October 1, 2013, 14 results in an electric revenue requirement of $7.825 15 million, or a 3.1% increase, and a natural gas revenue 16 requirement of $1.330 million, or a 2.0% rate increase. Net 17 rate base for electric and natural gas is $659.04 million 18 and $116.07 million, respectively, effective October 1, 19 2013. 20 Q. Please explain the offset agreed to by the Parties 21 to mitigate the overall impact of the electric October 1, 2013 base rate increase. 23 A. Effective October 1, 2013, coincident with the 24 electric base rate change described above, for rate Norwood, Di 23 Avista Corporation 1 mitigation purposes, the Company would amortize a $3.865 2 million credit resulting from a payment to be made to Avista 3 by the Bonneville Power Administration (BPA) relating to the 4 prior use of Avista's transmission system. 5 In December 2012, Avista and Bonneville reached a 6 settlement pertaining to the prior and future use of 7 Avista's transmission system by Bonneville. BPA Settlement 8 Revenue of $3.865 million represents Idaho customers' share 9 of the $12.224 million (system) to be paid by BPA for its 10 prior use of Avista's transmission system5 . The settlement 11 was intended to resolve the issue of compensation to Avista 12 for the prior use of its transmission system by BPA, as well 13 as provide Bonneville with continuing access to transmission 14 in lieu of it constructing additional transmission 15 facilities at this point in time. 16 On February 5, 2013, Avista received approval from the 17 Federal Energy Regulatory Commission (FERC) (Docket No. ER13- 18 689-000) for the settlement filed on December 31, 2012. 19 Avista would amortize the BPA settlement revenue over 20 15-months from October 1, 2013 to December 31, 2014, which 21 reduces the overall bill increase to customers on October 1, 22 2013 from 3.2 to 1.91. For prior periods up through February 28, 2013. Norwood, Di 24 Avista Corporation I Q. Please explain the offset agreed to by the Parties 2 to mitigate the overall impact of the natural gas October 1, 3 2013 base rate increase. 4 A. Effective October 1, 2013, coincident with the 5 natural gas base rate change described above, to partially 6 offset the base rate increase, the Company would amortize 7 the $1.55 million PGA deferral credit balance resulting from 8 the 2012 PGA, over 15-months, October 1, 2013 to December 9 31, 2014. This PGA deferral credit balance results from 10 Docket AVU-.G-12-05, in which the Commission approved Staff's 11 proposal that approximately $1.55 million in un-refunded 12 credit balances be held back due to the Company's filing of 13 a "Notice of Intent to File a General Rate Case." The 14 Commission stated in Order 32651, on page 6, that "the 15 resulting $1.55 million un-refunded credit balance will help 16 mitigate potential rate increases and provide rate stability 17 for customers." This credit would reduce the overall bill 18 increase to customers effective October 1, 2013 from 2.0% to 19 0.3%. 20 21 IV. OTHER ELEMENTS OF THE STIPULATION 22 Q. Please explain the settlement terms relating to 23 the PCA authorized level of expenses. Norwood, Di 25 Avista Corporation 1 A. The new level of power supply expense, retail load 2 and Clearwater Paper generation, for purposes of monthly PCA 3 calculations, are detailed in Attachment B of the 4 Stipulation and Settlement provided as Exhibit No. 1. The 5 Parties agree for settlement purposes to accept the 6 Company's normalized load forecast without specifically 7 accepting the weather normalization methodology or the 8 proposed Energy Efficiency Load Adjustment. 9 Q. Please explain the settlement terms relating to 10 Depreciation Rates. 11 A. The Parties have agreed to the updated electric 12 and natural gas depreciation rates as filed by the Company, 13 with all common/allocated plant depreciation rates, 14 including the new depreciation rates for transportation 15 equipment, effective January 1, 2013 to coincide with the 16 Company's Washington and Oregon jurisdictions; the remaining 17 direct Idaho plant depreciation rate changes would be 18 effective April 1, 2013. 19 Q. Please explain the settlement terms relating to 20 the after-the-fact earnings test for 2013 and 2014. 21 A. The Company agrees to an after-the-fact earnings 22 test, where it would refund to customers one-half of any 23 earnings in excess of the agreed-upon 9.8W ROE for each of 24 the years 2013 and 2014, to allay any concerns that the base Norwood, Di 26 Avista Corporation 1 rate relief in April 1, 2013 and October 1, 2013 may allow 2 the Company to exceed its authorized return. The earnings 3 test would be based on actual, consolidated results for 4 Idaho electric and natural gas operations. 5 Q. Please explain the settlement terms relating to 6 the rate freeze / stay-out agreed to by the Parties. 7 A. The Parties agree that, in recognition of the two- 8 year rate plan covered by this Stipulation, Avista would not 9 file another electric or natural gas general rate case 10 before May 31, 2014, and while it may request an effective 11 date earlier than January 1, 2015, final approved new rates 12 would not go into effect prior to January 1, 2015. This 13 does not apply to tariff filings authorized by or 14 contemplated by the terms of the Power Cost Adjustment 15 (PCA), or the Purchased Gas Adjustment tariff (PGA), or 16 other miscellaneous filings. 17 Q. How does the Stipulation's two-year rate plan, 18 including the rate freeze / stay-out element, agreed to by 19 the Parties challenge Avista to manage its costs? 20 A. The two-year rate plan for the period 2013 and 21 2014 would only provide retail revenues sufficient to 22 provide Avista the opportunity to earn the return agreed to 23 by the Parties, if the Company undertakes aggressive cost 24 management measures now and going forward. Norwood, Di 27 Avista Corporation 1 As explained in Avista's direct testimony, the Company 2 is experiencing significant increases in plant investment 3 and non-fuel O&M expenses required to serve its customers, 4 both of which are growing at a much faster pace than its 5 retail sales. Although we continue to take extensive 6 measures to ensure that the costs that we are incurring 7 represent the most cost-effective and reliable way to 8 continue to serve our customers, while preserving a high 9 level of customer satisfaction, we continue to experience 10 significant increases in annual operating expenses. 11 Avista has put into place additional cost-management 12 measures, which combined with the rate adjustments in the 13 Settlement, will provide the Company a reasonable 14 opportunity to earn the return agreed to in the Stipulation. 15 As an example, in October 2012, Avista's Board of Directors 16 approved the Company's Voluntary Severance Incentive Plan 17 (VSIP), which was implemented in December 2012. Through this 18 program, effective January 1, 2013 Avista reduced its number 19 of employees by 55. 20 21 V. RATE SPREAD & RATE DESIGN 22 Q. Please explain the settlement terms relating to 23 cost of service. Norwood, Di 28 Avista Corporation I A. For electric operations, the Company prepared a 2 cost of service analysis using a peak credit method of 3 classifying production costs, allocating 100% of 4 transmission costs to demand, and allocating transmission 5 costs on a twelve-month basis. For settlement purposes, the 6 Parties agreed to use a pro-rata allocation based on the 7 Company's proposed 15% move towards unity for purposes of 8 spreading the revised electric revenue requirement, while 9 not agreeing on any particular cost of service methodology. 10 For natural gas operations, the Company proposed that 11 all rate schedules be moved approximately 25% towards unity. 12 For settlement purposes, the Parties agreed to use a pro- 13 rata allocation of the Company's natural gas rate spread 14 percentages from its original filing for purposes of 15 spreading the revised revenue requirement, without agreement 16 on any particular cost of service methodology. 17 Q. How did the Stipulation address rate design? 18 A. For settlement purposes, the Parties have agreed 19 that the revenue requirement for each electric and natural 20 gas service schedule would be applied as a uniform 21 percentage increase to each volumetric energy rate, as 22 shown in Attachment C of the Stipulation and Settlement 23 provided as Exhibit No. 1, and there would be no change to Norwood, Di 29 Avista Corporation I the residential electric Schedule 1 and natural gas 2 Schedule 101 basic charges. 3 Attachment C of the Stipulation provides a summary of 4 the current and proposed rates and charges for electric and 5 natural gas service. 6 Q. Please explain how the Stipulation addresses rate 7 spread/rate design related to the electric and natural gas 8 base rate offsets effective October 1, 2013. 9 A. The Parties have agreed that the electric base 10 rate offset related to the BPA Settlement Revenues would be 11 spread to electric rate schedules on a uniform cents per 12 kWh basis, and the natural gas base rate offset related to 13 the 2012 PGA deferral credit balance of $1.55 million would 14 be spread to natural gas rate schedules on a uniform cents 15 per therm basis. 16 Attachment D of the Stipulation contains the form of 17 tariff related to the electric and natural gas offsets 18 agreed to by the Parties. A new electric rate schedule, 19 Schedule 97, would be used for purposes of passing through 20 to customers the electric offset. A new natural gas rate 21 schedule, Schedule 197, would be used for purposes of 22 passing through to customers the natural gas offset. Both 23 tariffs would expire on December 31, 2014. Norwood, Di 30 Avista Corporation I Any under- or over-refunded amounts relating to the 2 electric or natural gas offsets would be trued up in the 3 following year's Power Cost Adjustment (electric) or 4 Purchased Gas Cost Adjustment (natural gas) filings. 5 6 VI. CUSTOMER SERVICE PROGRAMS 7 Q. Does the Company have programs in place to 8 mitigate the impacts on customers of the proposed rate 9 increases? 10 A. Yes. We have a history of making it a priority 11 within our Company to maintain meaningful programs to assist 12 our customers that are least able to pay their energy bills. 13 We also have programs to assist our entire customer base, 14 i.e., not just our low-income customers. Some of the key 15 programs that we offer or support are as follows: 16 • DSM Energy Efficiency Programs and Funding. The 17 Company offers a broad array of energy efficiency 18 program measures that provide customers with increased 19 opportunity to manage their energy bills. In 2012, 20 Avista hosted two Energy Fairs, one in Lewiston, and 21 the other in Coeur d'Alene. Over 280 customers were in 22 attendance and received energy efficiency tips and kits 23 that included low cost/no cost ways to reduce energy 24 consumption. 25 26 • Project Share. Project Share is a voluntary program 27 allowing customers to donate funds that are distributed 28 through community action agencies to customers in need. 29 In addition to the Idaho customer contributions during 30 the 2011/2012 program year of $66,490, the Company also 31 contributed $69,421 (Idaho's share) to the program. Norwood, Di 31 Avista Corporation 1 2 • Comfort Level Billing. The Company offers the option 3 for all customers to pay the same bill amount each 4 month of the year by averaging their annual usage. 5 Under this program, customers can avoid unpredictable 6 winter heating bills. 7 8 • Payment Arrangements. The Company's Contact Center 9 Representatives work with customers to set up payment 10 arrangements to pay energy bills. 11 • CARES Program. Customer Assistance Referral and 12 Evaluation Services provides assistance to special- 13 needs customers through access to specially trained 14 (CARES) representatives who provide referrals to area 15 agencies and churches for help with housing, utilities, 16 medical assistance, etc. 17 18 • Senior Energy Outreach: Avista has developed specific 19 strategic outreach efforts to reach our more vulnerable 20 customers (seniors and disabled customers) with bill 21 paying assistance and energy efficiency information 22 that emphasizes comfort and safety. Some examples of 23 this effort are as follows: 24 25 • Senior Publications: Avista has created a one- 26 page advertisement that has been placed in senior 27 resource directories and targeted senior 28 publications to reach seniors with information 29 about energy efficiency, Comfort Level Billing, 30 Avista CARES and energy assistance. A brochure 31 with the same information has also been created 32 for distribution through senior meal delivery 33 programs and other senior home-care programs. 34 35 • Senior Energy Workshops: With the help of 36 additional workshop presenters, 9 Senior Energy 37 Workshops were held during 2012 in Idaho. Over 38 393 seniors were reached and were given Senior 39 Energy Efficiency kits along with learning about 40 low-cost/no-cost ways to reduce energy use. 41 Norwood, Di 32 Avista Corporation 1 VI. CONCLUSION 2 Q. In conclusion, why is this Stipulation in the 3 public interest? 4 A. This Stipulation strikes a reasonable balance 5 between the interests of the Company and its customers, 6 including its low-income customers. As such, it represents 7 a reasonable compromise among differing interests and 8 points of view. 9 The terms of the Settlement agreement represent a two- 10 year rate plan designed to provide necessary retail 11 revenues. For its part, the Company will continue to 12 closely manage its costs during this two-year period. The 13 Parties have agreed that the Company has demonstrated the 14 need for revenue requirement increases for both its 15 electric and natural gas operations, thus providing 16 recovery of its costs over the two-year rate period. 17 Therefore, the Stipulation is designed to address the 18 multiple purposes of addressing the Company's revenue 19 requirement needs; minimizing the impact to customers from 20 changes in retail rates; providing rate certainty over the 21 two year period 2013-2014; and reducing the administrative 22 burden to all parties and the Commission associated with 23 this general rate case, as well as avoiding another rate 24 filing in 2013 for new rates in 2014. It also provides a Norwood, Di 33 Avista Corporation I form of price cap regulation under which the Company is 2 expected to manage its costs under the given rates to earn 3 a fair return. 4 In the final analysis, however, any settlement 5 reflects a compromise in the give-and-take of negotiations. 6 The Commission, therefore, has before it a Stipulation that 7 is supported by sound analysis and supporting evidence, the 8 approval of which is in the public interest. 9 Q. Does this conclude your pre-filed direct 10 testimony? 11 A. Yes, it does. Norwood, Di 34 Avista Corporation . . DIRECT TESTIMONY OF KELLY 0.

INTRODUCTION 1. The terms and conditions of this Stipulation are set forth herein. The Parties agree that this Stipulation represents a fair, just and reasonable compromise of all the issues raised in the proceeding and that this Stipulation and its acceptance by the Commission represents a reasonable resolution of the multiple issues identified in these cases. The Parties, therefore, recommend that the Commission, in accordance with RP 274, approve the Stipulation and all of its terms and conditions without material change or condition. II. BACKGROUND 2.On October 11, 2012, Avista filed an Application with the Commission for authority to increase revenue from electric and natural gas service in Idaho by 4.6% and 7.2%, respectively. If approved, the Company's revenues for electric base retail rates would have increased by $11.4 million annually; Company revenues for natural gas service would have increased by $4.6 million annually. The Company requested an effective date of April 1, 2013 for its proposed electric and natural gas rate increases. By Order No. 32689, dated December 4, 2012, the Commission suspended the proposed schedules of rates and charges for electric and natural gas service. 3.Petitions to intervene in this proceeding were filed by Clearwater, Idaho Forest, CAPAI, the Idaho Conservation League, and the Snake River Alliance. By various orders, the Commission granted these interventions. See, IPUC Order Nos. 32678, 32680 and 32687. 4.Settlement conferences were noticed and held in the Commission offices on January 17 and 24, 2013, and were attended by signatories to this Stipulation; further discussions ensued. Based upon the settlement discussions among the Parties, as a compromise of positions STIPULATION AND SETTLEMENT - AVU-E-12-08 & AVU-G-12-07 Page 2 in this case, and for other consideration as set forth below, the Parties agree to the following terms: III. TERMS OF THE STIPULATION AND SETTLEMENT 5. Overview of Settlement and Revenue Requirement. The Parties agree that Avista should be allowed to implement revised tariff schedules designed to recover the following revenue requirement in two steps, as summarized in Attachment A, and below: Electric Step 1: April 1. 2013 a. No electric base rate change effective April 1, 2013, instead of the proposed 4.6%, or $11.393 million. Step 2: October 1. 2013 a.Overall electric base rate increase of 3.1% (3.2% in billed rates) or $7.825 million effective October 1, 2013. b.Offsets - Apply $3.865 million for rate mitigation purposes (the BPA Parallel Operation Settlement 2), and amortize that offset over 15 months, from October 1, 2013 to December 31, 2014. C. Net overall bill increase to customers of 1.9% effective October 1, 2013. Summary of Electric Rate Changes Billing Rate Net Billing Change Oflet Rate Change April 1, 2013 0.0% 0.0% 0.0% October 1, 2013 3.2% -1.3% 1.9% 2 The BPA Settlement Revenue of $3.865 million represents the Idaho customers' share of $12.224 million (system) for the past use of Avista's transmission system for the period January 2005 through February 2013. In December 2012, Avista and Bonneville reached a settlement that pertains to the use of Avista's transmission system by Bonneville. Avista and Bonneville each own and operate transmission systems that are interconnected at various points. Between June 1998 and December 2009, Bonneville integrated four generation projects onto its 115 kV transmission system in the Walla Walla, Washington area. Bonneville sold transmission capacity to wind projects totaling 336 MW. The transmission path for these four projects follows a single Bonneville line that has a rated capacity of only 203 MW. Upon Avista's discovery of this situation, Avista asserted that Bonneville requires the use of up to 133 MW of parallel capacity support through the Avista system in order to fulfill Bonneville's transmission service obligations for these wind projects. The Settlement Agreement was intended to resolve the issue of compensation to Avista for the prior use of its transmission system, as well as provide Bonneville with continuing cost-effective parallel capacity support in lieu of constructing additional transmission facilities at this point in time. Avista anticipates FERC approval of the Settlement in February 2013, after which Avista will bill Bonneville. STIPULATION AND SETTLEMENT —AVU-E-12-08 & AVU-G-12-07 Page 3 Natural Gas Step 1: April 1, 2013 a. Overall natural gas base rate increase of 4.9% (5.0% in billed rates) or $3.115 million, instead of the proposed 7.2%, or $4.561 million, effective April 1, 2013. Step 2: October 1, 2013 a.Overall natural gas base rate increase of 2.0% (2.0% in billed rates) or $1.330 million effective October 1, 2013. b.Offsets - Apply $1.550 million PGA deferral credit balance from 2012 PGA' to partially offset the base rate increase, amortized over 15 months, October 1, 2013 to December 31, 2014. C. Net overall bill impact to customers of 0.3% effective October 1, 2013. Summary of Natural Gas Rate Changes Billing Rate Net Billing Change Oflet Rate Change April 1, 2013 5.0% 0.0% 5.0% October 1, 2013 2.0% -1.7% 0.3% 6. Cost of Capital. The Settling Parties agree to a 9.8 percent return on equity, with a 50.0 percent common equity ratio, and adopt the capital structure and resulting rate of return as set forth below: Capital ProForma ProForma Component Structure Cost Weighted Cost Total Debt 50.00% 6.01% 3.01% Common Equity 50.00% 9.80% 4.90% Total 100.00% 7.91% In Docket AVU-G-12-05, the Commission approved Staff's proposal that approximately $1.55 million in un- refunded credit balances be held back due to the Company's filing of a "Notice of Intent to File a General Rate Case." The Commission stated in Order 32651, on page 6, that "the resulting $1.55 million un-refunded credit balance will help mitigate potential rate increases and provide rate stability for customers."

The Parties agree to amortize the Reardan Wind Project deferred balance of $1.747 million over a two-year period beginning April 1, 2013. 11.Amortization of 2013 Coyote Springs 2/Colstri12 Maintenance Deferral. The Parties agree that the amount deferred in 2013 related to the Company's O&M costs of its Coyote Springs 2 (C S2) natural gas-fired generating plant and its fifteen (15) percent ownership In May 2008, Avista purchased the Reardan Wind Project Site from Energy Northwest, the then-current developer, after it was demonstrated as the Company's least-cost option for securing a renewable resource for its customers, consistent with its 2007 Integrated Resource Plan. Avista later chose to delay the construction of the Reardan project and take advantage of much-lower costs for wind projects that emerged in 2011 (Palouse Wind). Avista recorded $4.0 million of site acquisition and preparation costs, of which approximately $1.7 million is Idaho's share. This includes approx. $0.37 million in AFUDC in accordance with Order No. 30611 (Case No. AVU-E-08-04) STIPULATION AND SETTLEMENT - AVU-E-12-08 & AVU-G-12-07 Page 8 share of the Colstrip 3 & 4 coal-fired generating plants will be amortized over three years, beginning with the implementation of new base rates resulting from the Company's next general rate case filing.5 B. NATURAL GAS 12. Overview of Natural Gas Revenue Requirement (April 1. 2013). Below is a summary table and descriptions of the Natural Gas revenue requirement components agreed to by the Parties: SUMMARY TABLE OF ADJUSTMENTS TO NATURAL GAS REVENUE REQUIREMENT EFFECTIVE APRIL 1, 2013 000s of Dollars Revenue Requirement Rate Base Amount as Filed: $ 4,561 $ 110,930 Adjustments: a.)

As previously described (see Paragraph 6 above). b.Remove 2013 Capital Additions. Reflects total depreciation expense and rate base, net of accumulated depreciation and accumulated deferred income tax, Per Order No. 32371 in Case No. AVU-E-1 1-01, in order to address the large variability in year-to-year O&M costs, beginning in 2011, the Company was allowed to defer changes in O&M costs related to its Coyote Springs 2 (C52) natural gas-fired generating plant located near Boardman, Oregon, and its fifteen (15) percent ownership share of the Colstrip 3 & 4 coal-fired generating plants located in southeastern Montana. The Company compares actual, non-fuel, O&M expenses for the Coyote Springs 2 and Colstrip 3 & 4 plants with the amount of expenses authorized for recovery in base rates in the applicable deferral year, and defers the difference from that currently authorized. The deferral occurs annually, with no carrying charge, with deferred costs being amortized over a three- year period, beginning in January of the year following the period costs are deferred. STIPULATION AND SETTLEMENT - AVU-E-12-08 & AVU-G-12-07 Page 9 as of year-end December 31, 2012. Moves certain 2013 capital additions to the October 1, 2013 rate change.6 c. Remove 2013 Expenses: Delay Recovery to October 1, 2013 Rate Change. i.Information Services & Technology. Removes the 2013 incremental information service and technology expenses as discussed above, to be included in the October 1, 2013 rate change. ii.Non-Exec Labor. Removes the 2013 incremental non-executive labor increases as discussed above, to be included in the October 1, 2013 rate change. d. 2013 Property Tax. Removes the 2013 incremental property tax expense, adjusting property tax expense to December 31, 2012 levels. e. Remove Officer Incentive and CPI Escalation. Removes officer portion of incentives and removes the Consumer Price Index adjustment on incentives included in the Company's original filing. f. Miscellaneous Adjustments. Includes a two-year amortization of Booz & Co. consulting fees, thereby reducing test period expenses, and removes certain other amounts related to injuries and damages, abandoned projects and depreciation study expenses. 6 In the Company's filed case, inclusion of total net plant, including accumulated depreciation and accumulated deferred income tax on an average-of-monthly-average basis for 2013, had the effect of reducing rate base by $ 1.309 million and increasing revenue requirement associated with a net increase in depreciation expense by $22,000. This is due to the original filed adjustment that depreciated all plant, including the plant in service balance at December 31, 2012, to the AMA balance at December 31, 2013. The additional accumulated depreciation on plant in service at December 31, 2012 was greater than the net plant additions in 2013 on an AMA basis, which had an overall impact of reducing net rate base.

OTHER SETTLEMENT COMPONENTS 14.PCA Authorized Level of Expense. The new level of power supply expense, retail load and Clearwater Paper generation, and the April 1, 2013 and October 1, 2013 Load Change Adjustment Rates resulting from the April 1, 2013 and October 1, 2013 settlement revenue requirements for purposes of the monthly PCA mechanism calculations, are detailed in Attachment B. The parties agree for the purpose of Settlement in this case to accept the Company's normalized load forecast without specifically accepting the weather normalization methodology or the proposed Energy Efficiency Load Adjustment. 15.Depreciation Rates. The Parties have agreed to the updated electric and natural gas depreciation rates as filed by the Company, with all common/allocated plant depreciation rates, including the new depreciation rates for transportation equipment, effective January 1, 2013 to coincide with the Company's Washington and Oregon jurisdictions, with the remaining direct Idaho plant depreciation rate changes effective April 1, 2013. 16.Earnings Test. The Company agrees to an after-the-fact earnings test, where it would refund to customers one-half of any earnings in excess of the 9.8% ROE for each of the years 2013 and 2014, to allay any concerns that the base rate relief in April 1, 2013 and October 1, 2013 may allow the Company to exceed its authorized return. The earnings test would be based on actual, consolidated results for Idaho electric and natural gas operations. 17.Rate Freeze/Stay Out. The Parties agree that, in recognition of the two-year rate plan covered by this Stipulation, Avista will not file another electric or natural gas general rate case before May 31, 2014, and while it may request an effective date earlier than January 1, 2015, final approved new rates will not go into effect prior to January 1, 2015. This does not apply to tariff filings authorized by or contemplated by the terms of the Power Cost Adjustment (PCA), or the Purchased Gas Adjustment tariff (PGA), or other miscellaneous filings. STIPULATION AND SETTLEMENT —AVU-E-12-08 & AVU-G-12-07 Page 12 D. COST OF SERVICE/RATE SPREAD/RATE DESIGN 18. Cost of Service. For electric operations, the Company prepared an analysis using a peak credit method of classifying production costs, allocating 100% of transmission costs to demand, and allocating transmission costs on a twelve-month basis. For settlement purposes, the Parties agreed to use a pro-rata allocation based on the Company's proposed 15% move towards unity for purposes of spreading the revised electric revenue requirement, while not agreeing on any particular cost of service methodology. For natural gas operations, the Company proposed that all rate schedules be moved approximately 25% towards unity. For settlement purposes, the Parties agreed to use a pro-rata allocation of the Company's natural gas rate spread percentages from its original filing for purposes of spreading the revised revenue requirement. 19. Rate Spread/Rate Design (Base Rate Changes). (a)As indicated above, the Parties agreed that the increase in base revenues would be spread to all electric and natural gas rate schedules on a pro-rata allocation of the Company's rate spread percentages from its original filing. (b)The Parties agree that the revenue requirement for each electric and natural gas service schedule will be applied as a uniform percentage increase to each volumetric energy rate as shown in Attachment C. The Parties agree that there will be no change to Schedule 1 and Schedule 101 basic charges. (c)Attachment C provides a summary of the current and revised rates and charges (as per the Settlement) for electric and natural gas service. 20. Rate Spread/Rate Design (Offsets). STIPULATION AND SETTLEMENT - AVU-E-12-08 & AVU-G-12-07 Page 13 (a)The Parties have agreed that the electric base rate offset related to the BPA Settlement Revenues will be spread to electric rate schedules on a uniform cents per kWh basis. (b)The Parties have agreed that the natural gas base rate offset related to the 2012 PGA deferral credit balance of $1.55 million will be spread to natural gas rate schedules on a uniform cents per therm basis. (c)Attachment D contains the form of tariff related to the electric and natural gas offsets agreed to by the Parties. A new electric rate schedule, Schedule 97, will be used for purposes of passing through to customers the electric offset. A new natural gas rate schedule, Schedule 197, will be used for purposes of passing through to customers the natural gas offset. Both tariffs would expire on December 31, 2014. (d)Any under- or over-refunded amounts relating to the Electric or Natural Gas offsets will be trued up in the following year's Power Cost Adjustment (electric) or Purchased Gas Cost Adjustment (natural gas). 21.
