SUI,II{ARY OF ORIGINAI, FILING O. Please describe the Company's general- rate case requestr ds filed. A. On January Application with the Avista filed an for authority to j-ncrease 2027, and September 7, gas service in ldaho. The Company proposed an or 0.1% for "Rate 29, 2021, Commission 2022, for electric September t, and natura] Company proposed a "Two-Year Rate Plan" with an increase in electric base revenue of $24.8 million or 10.1? for "Rate Year 1", and $8.7 mil]ion or 3.22 for "Rate Year revenue effective 2". With regard to natura1 9ds, the increase in base revenue of $52r 000 Andrews, Di 2Avista Corporation 25 79 Year !", and $1.0 mj-l-Ilon or 2.2% for "Rate Year 2". By Order No. 34930, dated February 23, 2A21, the Commission provided notice of the Application and set an intervention deadline for lnterested persons and parti-es to intervene in the case. In its filed case, Avlsta proposed that these increases would be offset by the Andrews, Di 2aAvista Corporation 20 effect of Tax Customer Credit Tariff Schedules 76 (electric) and 1,76 (natural gas). Avista stated the proposed electric amortization of approxi-mately $31. 3 mill-ion 1n tax benefits from Schedule f6, beginning on September t, 202L, requested electric about November 30, would completely offset Avista's 2022. However, Avista also represented see an $8.7 10-year amortj-zation of $12.1 million 1n tax benefits from Schedule 116, beginning $1.2 million202L, would resul-t in about The Company stated that these benefits would base rate proposed (as-filed) $0.1 million natural gas increase in Rate Year 7, decreasing natural gas bill-s by about 1. 8%. For Rate Year 2 Avista proposed to amortize its customers' rate relief for Rate Year 1 until that its Idaho electric customers would million (3.52) bill increase for Rate Year 2, effectj-ve September L, 2022. Avista also stated the proposed natural- gas September L, j-n benefits per year. offset the "Natural- Gas Deferred Depreciation Expense" bal-ance of about $0.9 million for one-year, effective September L, 2022 through August 31, 2023. Avista also proposed offsetting the proposed $1.0 milllon revenue requirement increase through Schedule 117. The Company represented that, after applj-cation of Schedule L76 and 1,77 impacts, customers would see a 0.1% increase, effective September 1 2 3 4 5 6 1 I 9 10 11 !2 l_3 t4 15 t6 t7 18 19 20 27 22 23 24 Andrews, Di 3Avista Corporation 25 27 !, 2022. The Company used the results of the electric and natural gas cost of service studies (sponsored by Ms. Knox and Mr. Anderson) as a guide to spread the general increase. In this case, for electric operations, the study showed Residential Servj-ce Schedule 01 and Extra-Large General Service Schedule 25 provide less than the overall rate of return under present rates. AII of the other service schedules provide more than the overall rate of return under present rates to varying degrees. For 1 2 3 4 5 6 1 B 9 10 1l_ 13 L4 15 t6 77 1B 19 20 27 72 22 23 24 Andrews, Di 3aAvista Corporatj-on 25 22 natural gas operations, the study indicated that the General Service Schedule 101 (serving most residential customers) is providlng l-ess than the overa1l rate of return (unity), and Large General-, and Transportation service schedules (111/L1,2 and 1,46) are providing more than unity. O. What are the primary factors driving the Company's need for an electric and natural gas change in rates ? A. The primary factors driving the Company's electric and natural gas revenue requirements in Rate Year 1 (RY1) and Rate Year 2 (RY2) is an increase in net plant j-nvestment (including return on i-nvestment, depreciation and taxes, and offset by the tax benefit of interest) from that currently authorized. For RY1, electric net power supply expenses also contribute to the incremental e1ectric revenue requirement. Other changes irnpacting relate to the Company's revenue requirement requests increases in distribution, operation and maintenance (O&M),and administrative and general (A&G) electrj-c and natural- gas operations,expenses compared for both to current authorized 1evels. Electric specific capital investments for the 2020/2021 period incl-ude, among other things, upgrades to certain major generating faciJ-ities, such as the Long 1 2 3 4 5 6 1 B 9 10 11 t2 13 L4 15 1,6 77 18 L9 20 2L 22 23 24 Andrews, Di 4Avista Corporati-on 25 23 Lake Stabillty Enhancement and Upgrade, CS2 Single Phase Transformer, Cabinet Gorge Automation and Upgrades, and Llttl-e Fal1s Powerhouse Redevelopment, ds wel-1 as capital investment associated with the Cl-ark Eork and Spokane River License agreements, discussed by Company witness Mr. Thackston. For natural 9ds, specific capital investments over the period 2020/2021 period include, among other things, capital investments related to the Gas Eacilities 1 2 3 4 5 6 7 I 9 10 11 t2 13 L4 15 1-6 77 18 19 20 21 22 23 24 Andrews, Di 4aAvista Corporation 25 24 I 2 3 4 5 6 7 8 9 10 11 L2 13 t4 15 76 t7 18 19 20 2L 22 Z3 24 Replacement (Aldyl A) and Jackson Prairie Joint Project, as well as Gas Replacement Street and Highway Program, discussed by Company witness Ms. Rosentrater. For power supply, on direct, as discussed by Company witness Mr. Kalich, the level of ldaho's share of power supply expense for RY1 pro formed into this case had increased by approximately $7.1 million ($21.6 million on a system basis), from the l-evel currently included in base rates. This j-ncrease in expense was primarily due to gas. In addition, $3.6 million (of incl-usion of the power supply expenses the $7.1 million) as a were higher by result of the the increase in the price of natural Palouse and Rattl-esnake wind power trackedpurchase through agreements (PPA), which are currently the Company's Power Cost Adjustment (PCA) . III. SUM}'ARY OF SETTLEMENT STIPT'I.ATION O. Wou1d you bri-efIy summarj-ze the Stipulation? A. Yes. Under the terms of the Stipulation, as di-scussed further by Mr. Ehrbar, Avista would implement revj-sed tariff schedul-es designed to j-ncrease annual base electric revenues by $10.6 million, or 4.3eo, effective September L, 2021, and increase base revenues by $8.0 millionr er 3.13, effective September 1-, 2022.

These rate changes are designed to provide retail revenues necessary to alIow the Company the opportunity to earn the rate of return agreed to in the Stipulation for RY1 and RY2. Andrews, Di 5aAvista Corporation 26 The Company would also Tax Customer Credits avail-able of approximately $31.3 million for 9as, through 17 6 (natura] electric and $L2.7 mill-ion for natural Tariff Schedul-es 76 (electric) and Parties agreed to apply the Tax Customer Credit for electric and natura1 gas over the Two-Year Rate Specifically, el-ectric, the Plan as described by Mr. Ehrbar.l as dj-scussed by Mr. Ehrbar, for RY1 Company would return an amount equal to the base rate increase. Eor RY2 electric, the Company woufd return the remainj-ng balance of the Tax Customer Credit, offsetting the overal-l- base rate increase effective September L, 2022. Eor natural gdsr the Company would begin returning the Tax Customer Credit September l, 202L, over a ten-year period.2 As noted by Mr. Ehrbar, effective September t, 2027 an electric residential customer using an average of 892 kj-lowatt hours per month would see a $0.49, or 0.6?, increase per month for a revised monthly bill of $86.L2. Effective September 7, 2022 an electric residential customer woul-d see a $0.31, or 0.4%, increase per month for a revised monthly bill of $86.43. For naturaf 9ds, effective September l, 2027 a natura1 gas resj-dentia.l- customer using an average of 63 therms per month woul-d see a $2.30, ox 4.52, decrease per month for return to customers the separate gas).

Effective September 1, 1 As described by Mr. Ehrbar, in recognition that certain rate schedules are generally above their refative cost of service, the Parties agree that Schedule 25P shoul-d receive 253 of the overall- percentage base rate changes for the September 1, 2021, and September L, 2022 base rate increases. In addition, Schedules 1-1- /12 shoul-d receive 25* of the overall percentage base rate change for the September 1, 2022 increase. Al-l- other schedules, except Schedufe l-, should receive a uniform percentage of the overall- base rate revenue increase. The remaining revenue requirement shou1d be spread to Schedufe 1. For natural gas, the Parties agreed to a uniform percentage of distribution margin increase on September 1, 202L and September 1, 2022.2 Eor the Natura] Gas Tax Credit amortization, the Parties agree to begin amortizing the Company's natural gas tax basis benefit over ten years in this case and carrying through the Two-Year Rate Plan. However, the amortization period of the remaining balance available at the time of the Company's next general rate case wil-I be subject to review and possible change of the amortization period at that time. Andrews, Di 6a Avj-sta Corporation 25 28 1 2 3 4 5 6 1 I 9 2022 a natural gas residential customer woul-d see a $0.76, or 7.6e", i-ncrease per month for a revised monthly bill of $47. 95. In determining these revenue changes, the Parties have agreed to various adjustments to the Company's original filing, which are summarized in the Stipulation, and described further in the testimony bel-ow. The Stipulation cal1s for an overall rate of return of 7.058, determined using a capital structure consisting of 50% common stock equity and 50% debtr drr authorj-zed return on equity of 9.4% and cost of debt of 4.7%. With regard to the Two-Year Rate P1an, during the September l, 2027 - August 31, 2023 rate period covered by this Stipulation, Avj-sta will not file another electric or natural- gas general rate case to increase base rates before February t, 2023, and any such rates wil-l- not go into ef fect prior to September 1-, 2023. This does not apply to tariff filings authorized by or contemplated by the terms of the PCA, FCA, Purchased Gas Cost Adjustment (PGA) , oy other miscellaneous annual/regular tariff filings. Lastly, the Parties agreed to certain rate spread and rate design changes as descrj-bed by Mr. Ehrbar 10 1l_ 72 13 14 15 L6 L7 18 t9 20 2t 22 23 24 Andrews, Di 1Avista Corporati-on 25 29 1 2 3 4 5 6 7 8 9 10 t_1 t2 13 L4 l-5 'J,6 L7 18 19 20 2L 22 23 24 in his supporting testimony, as well as other Stipulation components related to the PCA and FCA, as well as agreed-upon workshops and meetings/conferences. O. Please explain how the Parties arrived at the Stipulation in this proceedinE. A. The Stipulation is the product of settlement discussions held virtually on May 19, 2027 and June 4, 202L. It represents a compromise among differing Andrews, Di 7aAvista Corporation 25 30 1 2 3 4 5 6 7 8 9 points of view, with concessions made by the Parties, to reach a bal-ancing of interests. The Stipulation represents a fair, just and reasonabl-e compromise of the issues and is in the public interest. In addition, the Sti-pulation is the end result of extensj-ve audit work conducted through the discovery process3, including various virtual conference discussions with Commission Staff, and hard bargaining by the Parties in this proceeding. O. Why is the Stipulation in the public interest? A. The Stipulation is in the "public interest" for several reasons. The Stipulation was the product of the give-and-take of negotiation that produced an "end result" that is just and reasonable. In addition, it is supported by the evidence, demonstrating the need for rate adjustments to provide recovery of necessary expendJ-tures and investment, the costs of which are not of f set by a growth in sal-es margj-ns. The Stipulation enjoys broad-based support from a variety of constituencies, including CAPAI, Clearwater, Idaho Forest, ICL, Walmart, and Staff. In addition, with the use of Tax Customer Credits to offset base rate changes over the Two-Year Rate P1an, the Stlpulation provides no base rate change overal-l for electric customers in RYL, effective 1_0 11 L2 13 1,4 15 16 t1 18 L9 20 2L 22 23 24 Andrews, Di 8Avista Corporation 25 31 1- 2 3 4 5 6 7 I 9 10 11 L2 13 14 15 16 1,7 18 19 20 21 22 23 24 September l, 202L, and an overall reduction of 0.88 in RY2, effective September 7, 2022. For natural 9ds, customers will see an overall reduction of 4.5e" in RY1, effective September L, 2021,, and an overall increase of 1.5% in RY2, effective September 1-, 2022. 3Avista responded to over 218 production requests (including sub-parts) from the Parties.

The Company's as-filed adjustments were reduced by agreed-upon Colstrip capital and expense updates / Andrews, Di 2Aa Avl-sta Corporation 55 reflecting actual 2020 capital- additions and 2021/2022 capital addition updates provided during the process of the case. Pro Forma Colstrip Amortization Adjustments and the accounting below, reflects agreed to by the Partiesr ds descrj-bed modification for the approved treatment (with one transmission assets) by the IPUC to investment in the Colstrip Units 3 and 4recover Avista's generating facilities after refl-ecting an accelerated depreciation rate of 2021. This adjustment also reflects the recovery of Colstrip capital additions between January L, 2020 and August 31, 2023r oD an AMA basis for RY1 and RY2 within the Colstrip Regulatory Asset. In the Company's filed case, it explained that the Commission' s prior approval of the Colstrip Unit 3 and 4 accounting, per Order 34216 in Case No. AVU12 E-18-03, included the deferral- of Colstrip generation and transmission assets with acceferated depreciation to 2027, and the deferral of the excess amount of depreciation not included in customers' rates, be deferred in the Colstrip Regulatory Asset, with an amortization recovery over 30 years.

To accomplish this change in accounti-ng, the Company adjusted the depreciation expense to be calculated on the Colstrip Transmissj-on assets using the 1 2 3 4 5 6 7 8 9 10 11 72 13 74 15 16 L7 18 19 20 27 22 23 24 Andrews, Di 27aAvista Corporation 25 51 approved depreciation rates on non-Colstrip transmission assets. Due to the length of amortizati-on depreciation rates versus the regulatory period belng simJ-1ar, there j-s little impact of this change on the annuaf revenue requj-rement recovered from customers, but for moving expense from an amortization expense back to a depreciation expense. This a1lows for the Colstrip transmission assets to be useful- and depreciated after 2021 .

In this case, for el-ectric operations, the Company prepared an electric cost of servj-ce analysis that incorporated, among other things, a system load factor peak credit method of cl-assifying production costs, allocating 100% of transmission costs to demand, and allocating transmission costs on a twel-ve-month coincident peak aflocation factor. The Parties do not agree on any particular cost of service methodology. In recognition, however, that certain rate schedules are generally above their re1ative cost of service the Parties agree 8 25% of the that Schedule 25P should receive overall percentage base rate changes for the September 7, 202L and September L, 2022 base rate increases. In addition, Schedul-es 17/L2 shoul-d recej-ve 25e" of the overall percentage base rate change for the September l, 2022 increase. Al1 other schedules, except Schedule l, should recei-ve a uniform percentage of the t2 overal-l- base rate revenue increase. The remaining revenue requirement should be spread to Schedule 1. For natural gas operations, the Parties agreed to a unj-form percentage of distribution margin change on September t, 202L and September L, 2022.

Capital additions through August 3L, 2022, were incl-uded in the Company's proposed first-year increase and calculated on an Average of Monthly Averages ("AMA") basis. For the second year of the rate p1an, capital additions were included through August 31, 2023, and were also calculated on an AMA basis. The Company proposed using a capital structure of 50? equity and 50% debt, and a return on common equity ("ROE") of 9.9%, for an overall weighted average cost of capital of 7 .3%. O. How did the Company propose to mitigate the effect of its requested increase on customers? A. In Order No. 34906, the Commission approved the Company's Tax Accounting Application request authorizing it to change its accounting for federal income tax expense from a normalization method to a flow-through method for certain plant basis adjustments, including Industry Director Directive No. 5 ("IDD #5") and meters (Case Nos. AVU-E-20-L2 and AVU-3-20-07). The change in accounting method provided i-mmediate benefits to Idaho customers, which Avista recorded in a regulatoryl-iability account. 1 2 3 4 5 6 1 8 9 10 11 t2 13 14 15 16 L7 18 I9 20 27 22 23 24 AVU-E-21-01 & AVU-G-2L-01 07 /1.9/27 ENGLISH, D.

For Idaho natural gas customers, the Company proposed a ten-year amortization of the tax benefits, resulting in a first year decrease in bil-l-ed rates of approxj-mately 1.8%.

Staff reviewed the Companyrs labor expense, incentive pIans, and employee benefj-ts to ensure. the appropriate level of expenditures are included in rates. Staff reviewed both completed and proposed Company investments to determine the prudence of capital additions. Expenditures including pension expense, salaries, and O&M expenses were also examined.

In i-ts Application, Avista proposed a 50% conimon equity ratio and a 9.9eo ROE. The Parties agreed to a ROE of 9.4% while accepting the 503 common equity ratio. A 9.4% ROE reduces the Company's requested first-year el-ectric revenue requirement by approximately $2.9 mil-l-ion and requested first-year natural gas revenue requirement by approximately $0.6 mj-Il-ion. 0. How does the Settlement account for the Company's capital investments in net rate base? A. In its Application, the Company proposed to include capital investments through August 31, 2022, in the calcul-ation of net rate base for the first-year increase. The Parties agreed that only capital investments scheduled to be placed in service before August 37, 2021, will be included in the first-year revenue requirement. Those capital additions wil-l- be in service and benefitting customers when new rates are effective on September L, 2021. For the second-year increase effective September I, 2022, the Company proposed capital additions through August 37, 2023, to be included in the calcufation of net rate base.

Staff believes that an important aspect of a two-year rate plan is to provide rate stability and certaj-nty to customers. Although not explicitly stated in the Settlement, the Parties agreed that other than this two-year rate p1an, base rates from a general rate case filing would not increase before September 7, 2023. Stability and certainty in rates only occur if the Company does not file another general rate case during the two-year rate plan. Therefore, it is important that the Commission order in this case require the Company not to fil-e another general rate case with rates effective prior to September L, 2023. With that caveat, Staff believes the Settl-ement represents a fair, just, and reasonable compromise of the positions put forth by aI1 parties and is in the public j-nterest. Therefore, Staff recommends the Commission approve the Settl-ement without material changes or modj-fications. Colstrip Transuission fnvestments O.

The current level of Idahors share of the depreciatj-on expense ($2.A75 million annually) would continue to be recovered through December 31, 2027. The undepreciated balance as of December 31, 2021, and the ARO would be offset by $6.41 million of tax credj-ts derived from the Tax Cuts and Jobs Act of 2078. The remaining balance not recovered through depreciation will be recovered through the amortization of a Regulatory Asset (FERC Account No. 1,83.327 - Colstrip Regulatory Asset) and amortized over 34.15 years (beginning April L, 2019) through 2053. The Colstrip Regulatory Asset, net of accumul-ated deferred federal- income taxes, is j-ncluded in rate base. O. Does the Settlement change the accounting treatment for Colstrip Units 3 and 4? A.

I was concerned with the prudence of including the Company' s Application.Pal-ouse Wind in base PSE The Palouse Wind project base rates since it was originally submitted for base rate recovery in Case No. AVU-E-12-08. In that case, "Staff objected to the project because the Company acquired it to satisfy a Washington State Renewable Portfol-io Standard without any immediate need to serve l-oad. Moreover, Staff determined that the project's PSE would exceed project benefi-ts under near term normalized load and power supply conditions." Lobb, DI, Case No. AVU-E-12-08, p. 13. For settlement purposes in Case No. AVU-E-12-08, the net cost/benefits have been tracked and recovered through the Power Cost Adjustment ("PCA") mechanism with 902/702 Company,/Customer sharing band that effectively aIlows the Company to recover 90% of Pal-ouse's contribution to PSE. In the general rate cases that followed, the cost difference of the contract rates compared to market rates, including the comparison I completed in this case, have maintained a sizable di-fference supporting Staff's view that the project is uneconomic for Idaho as 1n has not been included in Idaho 1 2 3 4 5 6 1 I 9 10 11 12 13 14 15 76 l1 18 19 20 2! 22 23 24 AVU-E-21-01 & AVU-G-21-0L 07 /19 /21, LOUIS, M.

O. How were the concerns with Palouse Wind PSE addressed in the Sett]ement in this case? A. The Settlement maintains the same PCA treatment as in past general rate cases for the cost of Palouse Wind power, which on ba1ance with the overall Settlement, provides reasonable PSE for Idaho customers. Rattl-esnake Flat PSE Ad ustment O. What is your concern with the Rattlesnake Flat project rel-ative to PSE? A. Like the Palouse Wind project, I was concerned with the prudence of incl-uding Rattlesnake Elat in base PSE, especially since the project went online in 20L9 several- years before a need for capacity to meet load.1 Without a need for capacity, the project j-s required to meet an economic threshold defined by the next best alternative. As 1n the case of Pal-ouse Wind, I believe that market electricity cost for the same amount of generation serves as a good proxy for evaluation purposes. 1 December 2026 was the first capacity deficiency date authorized in Order No. 33958 at the time when the project went onl-ine. November 2026 was the first capacity deficiency date authorized in Order No.34981 when this case was filed. 1 2 3 4 5 6 1 I 9 10 11 72 13 74 15 L6 l1 18 L9 20 27 22 23 24 AVU-E-21-01 & AVU-G-2L_OL 07 /L9/21 LOUIS, M.

Staff's analysis in this case showed similar resul-ts as those in Case No. AVU-E-19-04 general rate case. Staff analysis showed the cost of the Rattl-esnake Fl-at project over the term of the contract being higher than market rates, even when adjusting for potential- REC revenue, wind integration costs, and network upgrade costs associated with the project. 0. How were concerns with the PSE of Rattlesnake Flat addressed in the Settl-ement in this case? A. The Sett.l-ement maintains the same PCA treatment for Rattlesnake Flat as was negotiated in Case No. AVU-E-19-04, by not including the cost of the project in base rates but flowing it through the PCA at 90%.

What other adjustments to PSE dld the Settlement address? A. The Settl-ement incorporated four other adjustments to PSE in base rates. Three of these adjustments represent a decrease in base PSE, while the fourth-an update in the natura1 gas price forecast- represents an increase in base PSE. The three adjustments that resul-ted in decreases were adjustments to costs and revenues with outside entities. These include (1) new fj-rm transmission contracts with fdaho Power that will earn the Company additional- revenue; (2) J-ncremental- transmission revenue that will- resul-t from a Eederal Energy Regulatory Commission rate case that will be completed by the end of 202L; and (3) a reduction in transmission cost resulting from a Bonneville Power Agency contract that was not renewed.

An historical test period is used to normafize loads and resource costs. Exceptions are the market natural gas and electricity price forecasts, which are major gas-flred that the drivers of dispatch cost for the Company's generators and fo r electricity market prices from the Mid-ColumbiaCompany purchases trading-hub. Because the forecasts are based on forward contract prices, they represent the best indicators of future natural gas and electricity prices, dt least in the near term when there is a sufficient volume of trading. Staff has historically requested the Company run its AURORA mode1 with the l-atest naturaL gas forecast to get the most accurate dispatch cost included in base PSE. In the past several general rate cases, wh11e the price of natural- gas was experiencing a declining trend, incorporating the l-atest natural gas price has resul-ted in updates to PSE in the customerrs favor.

(Stip) 9a STAE'F 25 137 A. The two-year rate plan in the Settlement util-izes available tax credits owed to customers as discussed in Staff witness English's direct testimony. The tax credits wou1d be used to offset portions of the increases in base rates over both years. The tax credits provided an opportunity for certain classes to make movements in the allocation of the revenue requirement to achieve greater equity based on their cost-of-service. Eor al-l- other classes that did not include movements toward cost-of-servj-ce, base rate increases were spread on a unj-form percentage basis. O. Please explain the movements in the cl-ass allocati-on towards cost-of -service in the Settl-ement. A. The primary principle in cost-of-service-based ratemaking is to assign costs to the customer cl-asses causing the cost so that rates for the various customer classes can be developed to recover the costs assigned to them. The Company's cost-of-service analysJ-s results incl-uded in Company witness Tara Knox's direct testimony provides the rate of return for each customer cl-ass based on current rates. Dividing the rate of return for each customer class by the overal-l- rate of return provides a Rel-ative Return Ratio for each customer cl-ass. A Return Ratio equal to one paying no more and no less customer class with a Rel-ative (or at unity) is assumed to be than its 1 2 3 4 EJ 6 1 B 9 10 11 L2 13 L4 15 t6 11 1B t9 20 2L 22 23 24 AVU-E-21-01 & AVU-G-2L-07 07 /te/2L ( StiP ) STAEE 25 138 LOUIS, M 10 cost-of-service.

This may negatively affect increase in base rate stability. After Year 2, the rates will be immediately reflected in customer's bil-ls without the offset from the tax credits. If the Company files another general rate case with an effective date soon after Year 2 ends, there will be an additional increase in customer rates. However, it is important to consider that the impact of the tax credit refunds to customers, regardl-ess of any other changes in rates automatically causes issues related to rate stability. It is the customer's money and the mere fact of provl-ding a refund will cause a temporary change in customer rates reflected in customer biIls. It is possible to refund the tax credit amount over a longer period to lessen the effects on rate stabllity; however, doing so intergenerational- equity. If causes issues with the body of customers who paid the period were extended, those taxes in the Company's rates may not necessarily be same customers receiving the refund due to customers who move into and out of the Company's service territory. Refunding the tax credit over a longer period to improve rate stability, would only increase these inequities.

There are no changes in the class allocation percentages of the revenue requj-rement for natural gas service in the Settlement.

Pl-ease discuss the j-ncrease 1n the electric and natural gas Residentia1 Basic Charge for Year 2. A. The last increase 1n the Basic Charge resul-ted from Case Nos. AVU-E-17-01 and AVU-G-17-01. The increase was $0.25 from $5.75 to $6.00 for electric service and $0.75 from $5.25 to $6.00 for natural gas service. The Basic Charge is designed to recover costs j-ncurred on a per customer basis and these costs do not vary with the amount of el-ectricity or natural gas consumed. Examples incl-ude bilting costs, meter reading costs, and the cost of the cost-of-service for the meter. The current amount in these expenses is over six times as much as the existing $6 per month Basic Charge. By increasing the basic charge, it will also reduce the volumetric ($ per kil-owatt-hour or $ per therm) portion of rates so customers shoul-d not see drastic changes in increase ratetheir total bill.
