EXECUTIVE SUMY 26 Proposed Electric Increase Page 2 page 6page8Page10 Page 13 page 23 Page 25 Page 27 27 Q.What is the proposed electric revenue increase in 28 thi s case and how is the Company proposing to spread the 29 total increase by rate schedule? 30 A.The proposed electric increase is $31,233,000, or 31 14.2% over present base tariff revenue/rates in effect. 32 The proposed general increase over present billing rates, 33 including all other rate adjustments (PCA,DSM and Hirschkorn, Di 2 Avista Corporation 1 is 12.8%.Wi th the proposedResidential Exchange), 2 decrease in the present Power Cost Adjustment (PCA) 3 surcharge of 5.0%, the net increase is 7.8% over present 4 billing rates. 5 The proposed general increase of $31,233,000 has been 6 spread by rate schedule on a basis which: 1) moves the 7 rates for nearly all the schedules closer to the cost of 8 providing service, and 2) resul ts in a reasonable range in 9 the increase theproposed percentage(net)across 10 schedules. The PCA surcharge is applied on a uniform cents 11 per kwh basis across all schedules and results in a 12 different percentage increase by schedule depending on the 13 By including thelevel of base tariff rates/revenue. 14 proposed decrease in the current PCA surcharge during 2009, 15 an opportunity is presented to move base tariff rates 16 closer to the cost of providing service.The proposed 17 increase over present billed rates/revenue by schedule is 18 shown below: 19 20 21 22 23 24 25 26 27 28 29 General Est.peA NetIncreaseDecreaseIncrease Residential Sch.1 13.1%-4.4%8.7% General Srvc.Sch.11 11. 6%-3.8%7.8% Lg.Gen.Srvc.Sch.21 12.7%-4.9%7.8% Ex.Lg.Gen.Srvc.Sch.25 14.5%-6.7%7.8% Potlatch-Lewiston Sch.25P 13.0%-7.3%5.7% Pumping Srvc.Sch.31 12.4%-4.6%7.8% Street & Area Lgt.Schs.10.5%-1. 6%8.9% Overall 12.8%-5.0%7.8% Hirschkorn,Di 3 Avista Corporation 1 This information is shown in detail on page 1, 2 Schedule 3 of Exhibit No. 12. 3 Q.In AVU-E-08-01, the Company stated that it is 4 perfor-ing a load research study and that the results will 5 not be available until late 2009/early 2010.Why is the 6 Company proposing to spread the general increase other than 7 on a unifor- percentage basis without the results of the 8 new load study? 9 A.As discussed in Witness Knox's testimony, the 10 Company performed a sensitivity analysis assuming varying 11 resul ts of the new load study.As shown on Schedule 4 of 12 Exhibit 11, the potential results of the load study would 13 not significantly change the results of the Company's cost 14 of service study presented in this filing. Given this, and 15 the effect of the proposed PCA decrease, the company did 16 not want to forgo this opportunity to adjust rates by 17 schedule closer to the cost of providing service. 18 Q.What is the proposed increase for a residential 19 electric customer with average consumption? 20 A.The proposed increase for a residential customer 21 using an average of 982 kWhs per month is $6.71 per month, 22 or an 8.6% increase in their electric bill.As part of 23 that increase,the Company is proposing that the 24 basic/customer charge be increased from $4.60 to $5.00 per 25 month. The present bill for 982 kWhs is $78.47 compared to 26 the proposed level of $85.18,including all rate 27 adjustments. Hirschkorn, Di 4 Avista Corporation 1 Q.Is the Company proposing any changes to the 2 present rate structures wi thin its electric service 3 schedules? 4 A.No.The Company is not proposing any changes 5 to the present rate structures within its electric 6 schedules. 7 Q. Where do you show the proposed changes in rates 8 within the electric service schedules? 9 A. This information is shown in detail on page 3, 10 Schedule 3 of Exhibit No. 12. 11 12 Proposed Natural Gas Increase 13 Q.HOW is the Company proposing to spread the 14 overall natural gas increase of $2,740,000, or 3.0%, by 15 service schedule? 16 A.The Company is proposing the following 17 revenue/rate changes by rate schedule: 18 19 20 21 22 23 24 General Service Schedule 101 3.1% Large General Service Schedule 111 2.5% Interruptible Sales Service Schedule 131 1. 7% Transportation Service Schedule 146 10.9% This information is also shown on page 1, Schedule 6 25 of Exhibit No. 12. The Company utilized the results of the 26 natural gas cost of service study, sponsored by Witness 27 Knox, as a guide in spreading the overall revenue increase Hirschkorn, Di 5 Avista Corporation 1 to its natural gas service schedules. 2 Q.What is the proposed monthly increase for a 3 residential natural gas customer with average usage? 4 A.The increase for a residential customer using an 5 average of 66 therms of gas per month would be $2.56 per 6 month, or 3.2%.A bill for 66 therms per month would 7 increase from the present level of $79.38 to a proposed 8 level of $81.94, including all present rate adjustments. 9 As part of this increase, the Company is proposing an 10 increase in the monthly customer charge of $0.25 per month, 11 from $4.00 to $4.25. 12 13 III. PROPOSED ELECTRIC REVENUE INCREASE 14 Proposed PCA Surcharge Reduction 15 Q.Please explain the Company's proposal to adjust 16 the electric PCA surcharge rate when the general rate 17 increase is implemented. 18 A.The Company proposes that the current PCA 19 surcharge rate of O. 610ç per kWh be reduced at the time the 20 general rate increase is implemented.The Company is 21 proj ecting that the surcharge rate can be reduced from 22 0.610ç to 0.257ç, representing a five (5) percent reduction 23 in rates to customers based on a reduced PCA surcharge. 24 This is based on the Company's power supply forecast(s) and 25 assumes that the rate change would occur on July 1, 2009. 26 The unrecovered PCA deferral balances would be 27 approximately $11.5 million at that time.The new, Hirschkorn, Di 6 Avista Corporation 1 surcharge rate of O. 257ç per kWh is designed to recover the 2 deferral balance over a 15-month period, July 1, 2009 3 through September 30, 2010. At the time the PCA surcharge 4 is reduced, it may be necessary to adjust the 15-month 5 amortization period or the surcharge reduction itself, 6 based on the timing of the general rate adjustment and 7 actual PCA entries as of that time. 8 Q.When would the Company submit a filing to change 9 the surcharge? 10 A.The Company would file the change to the 11 surcharge rate coincident with filing the new rates that 12 implement the general rate increase.The Company files 13 monthly PCA reports that show the actual PCA deferral 14 balances at the end of each month. 15 Q.Would the Company still make its annual filing to 16 review the PCA deferrals? 17 A.Yes.The Company would still make its annual 18 filing on or before August 1, 2009, to review PCA deferrals 19 for the period July 2008 through June 2009 as well as the 20 unrecovered balance of deferrals being recovered from the 21 existing surcharge.Staff would conduct its normal review 22 of the annual PCA filing. As a result of Staff's review, a 23 modification to the PCA surcharge rate, if necessary, could 24 be made by changing the PCA surcharge rate again on October 25 1, 2009. 26 27 Hirschkorn, Di 7 Avista Corporation 1 Sumary of Electric Rate Schedules and Tariffs 2 Q.Would you please explain what is dontained in 3 Schedule 1 of Exhibit No. 12? 4 A.Yes.Schedule 1 is a copy of the Company's 5 present and proposed electric tariffs, showing the changes 6 (strikeout and underline) proposed in this filing. 7 Q.Could you please describe what is contained in 8 Schedule 2 of Exhibit No. 12? 9 A.Yes.Schedule 2 contains the proposed (clean) 10 electric tariff sheets incorporating the proposed changes 11 included in this filing. 12 Q.What is contained in Schedule 3 of Exhibit No. 13 12? 14 A.Schedule 3 contains information regarding the 15 proposed spread of the electric revenue increase among the 16 service schedules and the proposed changes to the rates 17 wi thin the schedules.Page 1 shows the proposed general 18 revenue and percentage increase by rate schedule compared 19 to the present revenue under base tariff and billing rates, 20 as well as the proposed net percentage increase to billed 21 rates/revenue including the estimated decrease in the 22 current PCA surcharge.Page 2 shows the rates of return 23 and the relative rates of return for each of the schedules 24 before and after application of the proposed general 25 increase. Page 3 shows the present rates under each of the 26 rate schedules, the proposed changes to the rates within 27 the schedules (including the estimated PCA surcharge Hirschkorn, Di 8 Avista Corporation 1 reduction), and the proposed rates after application of the 2 changes.These pages will be referred to later in my 3 testimony. 4 Would you please describe the Company i s presentQ. 5 rate schedules and the types of electric service offered 6 under each? 7 The Company presently provides electricA.Yes. 8 service under Residential Service Schedule 1, General 9 Service Schedules 11 and 12 i Large General Service 10 Schedules 21 and 22, Extra Large General Service Schedules 11 25 and 25P (Potlatch's Lewiston Plant) and Pumping Service 12 Addi tionally, the Company providesSchedules 31 and 32. 13 Street Lighting Service under Schedules 41-46, and Area 14 Lighting Service under Schedules 47 -49.Schedules 12, 22, 15 32, and 48 exist for residential and farm service customers 16 who qualify for the "Residential Exchange" program operated 17 by the Bonneville Power Administration.The rates for 18 these schedules are identical to the rates for Schedules 19 respectively,except for the31,and 47,11,21, 20 Residential Exchange rate credit.The following table 21 shows the type and number of customers served in Idaho (as 22 of September 30, 2008) under each of the service schedules: 23 24 25 26 27 28 29 NO. of eustomersScheduleType of eustomer Residential Sch. 1 General Sch. 11&12 Lge.

What rationale did the company use in developing 24 the proposed general increase by rate schedule? 25 A. The company used the results of the cost of 26 service study sponsored by company witness Knox, as well as 27 the net increase resulting after application of the 28 es t ima ted 2009 decreas e in the current PCA surcharge. The 29 application of the proposed increase generally results in 30 the rates of return for the various service schedules Hirschkorn, Di 10 Avista Corporation 1 moving closer to the overall rate of return (unity).The 2 table below shows the relative rates of return (schedule 3 rate of return divided by overall rate of return) before 4 and after application of the proposed general increase: Lg.

Why is the Company proposing to spread the general 21 increase other than on a unifor- percentage basis without 22 the results of the new load study? 23 A. While a load study is currently underway, the 24 results of the study will not be available until early 25 2010. The Commission, in Order No. 30647 in Case No. AVU- 26 E-08~01, discussed the use of sensitivity studies in the 27 absence of a load study.Accordingly, the Company has 28 performed a sensitivity analysis of its cost of service Hirschkorn, Di 11 Avista Corporation 1 study results under several different outcomes of the load 2 study. As shown on Schedule 4 of Exhibit 11, and described 3 in Company witness Knox's testimony, the outcome of the 4 load study currently underway should not materially change 5 the results of the Company's present cost of service study, 6 i. e., those schedules whose rate of return is considerably 7 less than the overall rate of return would continue to be 8 less,and those schedules whose rate of return is 9 considerably above the overall rate of return would 10 continue to be above. Given the results of this analysis, 11 and the effect of the estimated PCA rate reduction 12 (different percentage reduction by schedule), the Company 13 did not want to forgo this opportunity to adjust rates by 14 schedule to move closer to the cost of providing service. 15 The Company believes that the proposed rate spread results 16 in a reasonable approach to moving the rates for most 17 schedules toward the cost of providing service. 18 Q. The relative rate of return for street and area 19 lighting schedules moves further away from unity after 20 application of the proposed increase (0.92 to 0.73). Why 21 is the compåny proposing an increase to these schedules 22 that yields this result? 23 A. Whereas the average reduction in the present PCA 24 surcharge across all schedules is 5.0%, the average PCA 25 reduction for street and area schedules is only 1.6%. This 26 is because most of the revenue under these schedules 27 applies to the capital recovery of lights and poles, and Hirschkorn, Di 12 Avista Corporation 1 the PCA is applied to the "energy" portion of the rate (s) . 2 Therefore, in order to achieve a reasonable net increase to 3 those schedules of 8.9%(general increase and PCA 4 decrease), the Company had to apply an average general 5 increase of 10.5% to those schedules, which is considerably 6 less than the overall general increase of 12.8%. 7 8 Proposed Rate Design 9 Q.Where in your Exhibit do you show a compari son of 10 the present and proposed rates within each of the company's 11 electric service schedules? 12 A.Page 3, Schedule 3 of Exhibit No. 12 shows a 13 comparison of the present and proposed rates wi thin each of 14 the schedules, which i will describe below.Column (a) 15 shows the rate/billing components under each of the 16 schedules, column (b) shows the base tariff rates wi thin 17 each of the schedules, column (c) shows the present rate 18 adjustments applicable under each schedule, and column (d) 19 shows the present billing rates.Co 1 umn ( e) shows the 20 proposed general rate increase to the rate components 21 within each of the schedules, column (f) shows the proposed 22 billing rates and colum (h) shows the proposed base tariff 23 rates. 24 Q.IS the Company proposing any changes to the 25 existing rate structures within its rate schedules? 26 27 A.No, it is not. Q.Turning to Residential Service Schedule 1, could Hirschkorn, Di 13 Avista Corporation 1 you please describe the present rate structure under this 2 schedule? 3 A.Yes.Residential Schedule 1 has a present 4 customer / basic charge of $4.60 per month and two energy 5 rate blocks:0-600 kWhs and over 600 kWhs.The present 6 base tariff rate for the first 600 kWhs per month is 6.552 7 cents per kWh and 7.416 cents for all kWhs over 600. 8 Q.How does the Company propose to spread the 9 proposed general revenue increase of $12,279,000 to 10 Schedule 1? 11 A.The Company proposes to increase the monthly 12 customer charge from $4.60 to $5.00, or 8.7%. The proposed 13 increase to the energy rate for the 0-600 kWh block is 14 0.907 cents/kWh and the proposed increase to the over 600 15 kWh block is 1.135 cents/kWh, or 125% of the increase 16 applied to the first block rate. 17 Q.Why is the Company proposing to increase the 18 monthly customer charge from $4.60 to $5.00 per month? 19 A.A substantial portion of the Company's costs are 20 fixed and do not vary with the amount of energy used by 21 customers.As reflected in this filing, the cost of 22 operating and maintaining our electric system is increasing 23 and the Company has been providing this message to 24 customers. The Company believes it is important that rates 25 at least partially reflect these increasing costs and allow 26 the Company a more reasonable opportunity to recover some 27 of these costs. However, the Company also understands the Hirschkorn, Di 14 Avista Corporation 1 controversial nature of residential "customer charges" and 2 is proposing only a relatively modest increase in the 3 charge. 4 Q.Why is the Company proposing a higher percentage 5 increase to the tail-block rate (over 600 kWhs) than to the 6 first-block rate? 7 A.By applying a higher percentage increase to the 8 tail-block rate, a stronger price-signal is provided to 9 customers regarding the higher incremental cost of 10 producing energy in the future. This price-signal provides 11 additional financial incentive for customers to use energy 12 more efficiently.Application of the proposed increase 13 results in a rate differential of approximately 1.1 cents 14 per kWh between the two block rates compared to the present 15 differential of 0.86 cents per kWh. 16 Q.Did the Company consider proposing the 17 implementation of an additional rate block in this filing 18 to provide an even stronger price signal to customers? 19 A.Yes, it did. However, given the current state of 20 the economy and other concerns, it chose not to propose 21 implementation of an additional inverted rate block in this 22 filing. 23 24 Q.Could you please explain these other concerns? A.Yes.The first concern is related to the 25 potential affect of further inverting rates on low- and 26 limited-income customers. The Company examined the average 27 annual usage of its Idaho residential all-electric (no Hirschkorn, Di 15 Avista Corporation 1 natural gas) customers that have received LIHEAP assistance 2 and those that have not received assistance. Over a recent 3 twelve month period, the average annual usage for customers 4 that have received assistance was 1,900 kWhs greater than 5 for those customers that did not.Looking at a small 6 sample of the customers that have received assistance, it 7 is apparent that many of these households utilize 8 electrici ty for home-heating and further inverting 9 residential rates could have a disproportionate effect on 10 these customers' bills. 11 The second concern relates to customer education 12 regarding inverted rates.While the Company has provided 13 customers with on-going information about energy-efficiency 14 programs and steps to conserve energy, more information 15 needs to be provided to customers regarding inverted rates 16 prior to implementing significant rate structure changes. 17 This information can then be used to help customers better 18 understand and manage their usage and monthly bill. 19 Lastly, the Company is concerned with the timely 20 recovery of its fixed costs as it relates to a further 21 inversion of residential rates.The proposed tariff rate 22 for residential usage in excess of 600 kWhs per month is 23 8.55 cents per kWh.This rate is well in excess of the 24 short-run marginal/incremental cost of energy and reflects 25 recovery of a significant level of fixed costs.Further 26 rate inversion would result in additional fixed costs 27 reflected/recovered through an even higher tail-block rate, Hirschkorn, Di 16 Avista Corporation 1 while usage billed at this rate will vary considerably 2 bas ed on wea ther . 3 Q.What is the average monthly electric usage for a 4 residential customer, and what is the effect of the 5 proposed increase on a customer's bill? 6 A.The average monthly usage for a residential 7 customer is 982 kWhs.Based on the proposed increase, 8 including the estimated reduction in the PCA surcharge, the 9 average monthly increase would be $6. 71, or 8.6%. The 10 present monthly bill for 1,000 kWhs of usage is $78.47 and 11 the proposed monthly bill would be $85.18, including all 12 rate adjustments. 13 Q.Turning to General Service Schedule 11, cOuld you 14 please describe the present rate structure and rates under 15 that Schedule? 16 A.Yes.The present rate structure under the 17 schedule includes a monthly customer charge of $6.50, an 18 energy rate of 7.295 cents per kWh for all usage under 19 3,650 kWhs per month, and an energy rate of 6.223 cents per 20 kWh for usage over 3,650 kWhs per month.There is also a 21 demand charge of $4.00 per kW for all demand in excess of 22 20 kW per month. There is no charge for the first 20 kW of 23 demand. 24 Q.How is the Company proposing to apply the 25 proposed general revenue increase of $3,485,000 to the 26 rates under Schedule 11? 27 A.The Company is proposing that the customer charge Hirschkorn, Di 17 Avista Corporation 1 be increased by $0.25, from $6.50 to $6.75 per month, and 2 that the demand charge (over 20 kW) be increased $0.25 per 3 kW, from $4.00 to $4.25. The remaining revenue increase for 4 the Schedule is proposed to be recovered through a uniform 5 percentage increase applied to the two (block) energy 6 rates. The increase in the first block rate is 1.082 cents 7 per kwh, and is 0.922 cents per kwh in the second block 8 rate. 9 Q.Turning to Large General Service Schedule 21, 10 could you please describe the present rate structure under 11 that Schedule and how the Company is proposing to apply the 12 increase of $6,506,000 to the rates within the schedule? 13 A. Large General Service Schedule 21 consists of a 14 minimum monthly charge of $275.00 for the first 50 kW or 15 less, a demand charge of $3.50 per kW for monthly demand in 16 excess of 50 kW, and a two-block energy rate (s) :5.384 17 cents per kWh for the first 250,000 kWhs per month and 18 4.594 cents per kWh for all usage in excess of 250,000 19 kWhs. 20 The Company is proposing that the present minimum 21 demand charge (for the first 50 kW or less) be increased by 22 $25 per month, from $275.00 to $300.00, and the demand 23 charge for kw over 50 per month be increased by $0.50 per 24 kW, from $3.50 to $4.00.The remaining revenue increase 25 for the Schedule is proposed to be recovered through a 26 uniform percentage increase applied to the two (block) 27 energy rates. The proposed increase for the first 250,000 Hirschkorn, Di 18 Avista Corporation 1 kWhs used per month under the schedule is 0.782 cents per 2 kWh, and an increase of 0.666 cents per kWh for usage over 3 250 , 000 kWhs per month. 4 Q.Turning to Extra Large General Service Schedule 5 25, could you please describe the present rate structure 6 under that Schedule and how the Company is proposing to 7 apply the increase of $2,398,000 to the rates within the 8 Schedule? 9 A.Extra Large General Service Schedule 25 consists 10 of a minimum monthly charge of $10,000.00 for the first 11 3,000 kVa or less, a demand charge of $3.25 per kVa for 12 monthly demand in excess of 3,000 kVa, and a two-block 13 energy rate(s): 4.411 cents per kWh for the first 500,000 14 kwhs per month and 3.736 cents per kWh for all usage in 15 excess of 500,000 kWhs. 16 The Company is proposing that the present minimum 17 demand charge under the schedule be increased by $1,000 per 18 month, from $10,000 to $11,000, and the demand charge for 19 kVa over 3,000 per month be increased by $0.50 per kVa, 20 from $3.25 to $3.75.The remaining revenue increase for 21 the Schedule is proposed to be recovered through a uniform 22 percentage increase applied to the two (block) energy 23 rates.The proposed energy rate increase for the first 24 500,000 kWhs used per month is 0.760 cents per kWh and the 25 increase for usage over 500,000 per month is 0.643 cents 26 per kWh. 27 Q.Did the Company consider implementing time-of-use Hirschkorn, Di 19 Avista Corporation 1 (TOU) rates for Schedule 25 customers in this Case? 2 A.Yes,it did.However,given the current 3 recession and its effect on the operations and financial 4 condition of many of these customers, the Company felt that 5 this was not the appropriate time to propose such a change. 6 Six of the twelve Schedule 25 customers manufacture wood 7 products. Because of the current recession, three of those 8 six customers have completely ceased production for an 9 indefinite period, and the other three have substantially 10 reduced production. Two of the remaining customers operate 11 silver mines and the future operation of those mines is 12 uncertain. 13 Q.What steps is the Company taking to assess the 14 possible implementation of TOU rates for these customers in 15 the future? 16 A.The Company has met with these customers to 17 discuss the possibility of implementing TOU rates in the 18 future. Most of these stated that it would be difficult 19 for them to shift a significant portion of their load to 20 off-peak periods because of labor and operational issues. 21 Nevertheless, the Company plans to again meet with and 22 gather additional information from each of these customers 23 during 2009 to assess their future operating plans and the 24 feasibility of implementing TOU rates in the future. 25 Q.Could you please describe the service the Company 26 provides to Potlatch's Lewiston Plant? 27 A.Yes.In Commission Order No. 29418, dated Hirschkorn, Di 20 Avista Corporation 1 January 15, 2004, the Commission approved a ten-year Power 2 Purchase and Sale Agreement (Agreement) between Avista and 3 Potlatch Corporation, applicable to Potlatch's Lewiston 4 Plant.The Agreement became effective July 1, 2003 and 5 expires June 30, 2013.The Agreement provides for the 6 purchase by Avista of Potlatch's on-site generation of up 7 to 62 average megawatts per year at a price of $42.92 per 8 megawa t t - hour.Power purchased from Potlatch under the 9 Agreement is a directly-assigned resource to Idaho (no 10 allocation to Washington). Avista serves Potlatch's entire 11 load requirement at the Plant, approximately 100 average 12 megawatts, under Schedule 25P.During the twelve months 13 ended September 30, 2008, Potlatch's generation was 49 14 average megawatts and their total load requirement was 104 15 average megawatts. 16 Q.Could you please describe the application of the 17 proposed increase of $5,694,000 to the rates under Schedule 18 25P? 19 A.Yes.The Company is proposing that the present 20 minimum demand charge under the schedule be increased by 21 $1,000 per month, from $10,000 to $11,000, and the demand 22 charge for kVa over 3,000 per month be increased by $0.50 23 per kVa, from $3.25 to $3.75.The remaining revenue 24 increase for the Schedule is proposed to be recovered 25 through an increase of 0.553 cents per kWh to the energy 26 charge. 27 Q.What changes is the Company proposing to the Hirschkorn, Di 21 Avista Corporation 1 rates under pumping Schedule 31 to recover the proposed 2 general revenue increase of $560, OOO? 3 A.The Company is proposing that the customer charge 4 be increased by $0.25, from $6.50 to $6.75 per month, with 5 the remaining revenue increase spread on a uniform 6 percentage basis to the two energy rate blocks under the 7 Schedule. The proposed increase in the first block rate is 8 1.015 cents per kWh and the increase in the second block 9 rate is 0.866 cents per kwh. 10 Q. How is the Company proposing to spread the 11 proposed revenue increase of $311,000 applicable to Street 12 and Area Light schedules, to the rates contained in those 13 schedules (Schedules 41-49)? 14 A.The Company proposes to increase present street 15 and area light (base) rates between 10.5% and 16.0% 16 depending on the Schedule.When the general percentage 17 increase is combined with the estimated PCA surcharge 18 decrease for each Schedule, the net proposed increase for 19 all lighting rates is 8.9%.The (base tariff) rates are 20 shown in the proposed tariffs for those schedules, 21 contained in Schedule 2 of Exhibit No. 12. 22 Q.Are you proposing any other changes to the 23 Company's electric service tariffs? 24 25 26 27 A.No. iv. PROPOSED NATURA GAS REVENU INCRESE Q.Could you please explain what is contained in Hirschkorn, Di 22 Avista Corporation 1 Schedule 4 of Exhibit No. 12? 2 A.Yes.Schedule 4 of Exhibit 12 is a copy of the 3 Company's present and proposed natural gas tariffs, showing 4 the changes (strikeout and underline) proposed in this 5 filing. 6 Q.Could you please describe what is contained in 7 Schedule 5 of Exhibit No. 12? 8 A.Schedule 5 of Exhibit No.12 contains the 9 proposed (clean) natural gas tariff sheets incorporating 10 the proposed changes included in this filing. 11 Q.Could you please explain what is contained in 12 Schedule 6 of Exhibit No. 12? 13 A.Yes.Schedule 6 of Exhibit No. 12 contains 14 information regarding the proposed spread of the natural 15 gas revenue increase among the service schedules and the 16 proposed changes to the rates wi thin the schedules. Page 1 17 shows the proposed general revenue and percentage increase 18 by rate schedule. Page 2 shows the rates of return and the 19 relative rates of return for each of the schedules before 20 and after the proposed increases. Page 3 shows the present 21 rates under each of the rate schedules, the proposed 22 changes to the rates wi thin the schedules, and the proposed 23 rates after application of the changes.These pages will 24 be referred to later in my testimony. 25 26 Sumry of Natural Gas Rate Schedules and Tariffs 27 Q.Would you please review the Company i s present Hirschkorn, Di 23 Avista Corporation 1 rate schedules and the types of gas service offered under 2 each? 3 A.Yes. The Company's present Schedules 101 and 111 4 offer firm sales service.Schedule 101 generally applies 5 to residential and small commercial customers who use less 6 than 200 therms /month .Schedule 111 is generally for 7 customers who consistently use over 200 therms/month. 8 Schedule 131 provides interruptible sales service to 9 customers whose annual requirements exceed 250,000 therms. 10 Schedule 146 provides transportation/distribution service 11 for cus tomer- owned gas for customers whose annual 12 requirements exceed 250,000 therms. 13 Q.The Company also has rate Schedules 112 and 132 14 on file with the Commission.Could you please explain 15 which customers are eligible for service under these 16 schedules? 17 A.Schedules 112 and 132 are in place to provide 18 service to customers who at one time were provided service 19 under Transportation Service Schedule 146. The rates under 20 these schedules are the same as those under Schedules 111 21 and 131 respectively, except for the application of 22 Temporary Gas Rate Adjustment Schedule 155.Schedule 155 23 is a temporary rate adjustment used to amortize the 24 deferred gas costs approved by the Commission in the prior 25 PGA.Because of their size,transportation service 26 customers are analyzed individually to determine their 27 appropriate share of deferred gas costs.If those Hirschkorn, Di 24 Avista Corporation 1 customers switch back to sales service,the Company 2 continues to analyze those customers individually; 3 otherwise,those cus tomers would receive gas costs 4 deferrals which are not due them, thus the need for 5 Schedules 112 and 132.There are presently only 3 6 customers served under these schedules. 7 Q.How many customers does the Company serve under 8 each of its natural gas rate schedules? 9 A.As of September 2008,the Company provided 10 service to the following number of customers under each of 11 its schedules: 12 13 14 15 16 General Service Sch. 101 71,472 Lg. General Service Sch. 111 846 Interruptible Service Sch. 131 1 Transportation Service Sch. 146 5 17 Proposed Rate Spread 18 Q.How does the Company propose to spread the 19 overall revenue increase of $2,740,000, or 3.0%, among its 20 natural gas general service schedules? 21 A.The Company is proposing the following 22 revenue/rate changes by rate schedule: Lg. General Service Sch. 111 3.1% 2.5% 23 24 25 26 27 General Service Sch. 101 Interruptible Service Sch. 131 1. 7% Transportation Service Sch. 146 10.9% Hirschkorn, Di 25 Avista Corporation 1 Q.Is the proposed increase for Transportation 2 Schedule 146 comparable to the increase for the other 3 service schedules? 4 A.No.The proposed increase for Transportation 5 Schedule 146 is not comparable to the proposed increases 6 for the other (sales) service schedules, as Schedule 146 7 revenue does not include an amount for the cost of gas or 8 pipeline transportation, whereas the other sales schedules 9 include those costs/revenue.(Transportation customers 10 acquire their own gas and pipeline transportation. ) 11 Including a conservative level of 50.0 cents per therm for 12 the cost of gas and pipeline transportation, the proposed 13 increase to Schedule 146 rates represents an average 14 increase of 2.0% in those customers' total gas bill, which 15 is then expressed on a relatively comparable basis to the 16 proposed increase (decrease) to the other (sales) service 17 schedules, and the overall proposed increase of 3.0%. 18 Q.What informtion did the Company use in 19 developing the proposed spread of the overall increase to 20 the various rate schedules? 21 A.The Company utilized the results of the cost of 22 service study, as sponsored by Witness Knox, as a guide in 23 developing the proposed rate spread. The relative rates of 24 return before and after application of the proposed 25 increases by schedule are as follows: 26 27 Hirschkorn, Di 26 Avista Corporation 1 2 3 4 5 6 7 Relative Rates of Return by Service Schedule Before Increase After Increase Schedule 111: 1. 02 0.91 1. 08 1. 01 0.95 Schedule 101: Schedule 131:1. 05 Schedule 146:1. 28 1. 29 8 Page 2 of Schedule 6 shows this information in more detail. 9 10 Proposed Rate Design 11 Q.Could you please explain the present rate design 12 within each of the Company's present gas service schedules? 13 A.Yes.General Service Schedule 101 generally 14 applies to residential and small commercial customers who 15 use less than 200 therms/month.The Schedule contains a 16 single rate per therm for all gas usage and a monthly 17 customer/basic charge. 18 Large General Service Schedule 111 has a four-tier 19 declining-block rate structure and is generally for 20 customers who consistently use over 200 therms/month. The 21 Schedule consists of a monthly minimum charge plus a usage 22 charge for the first 200 therms or less, and block rates 23 for 201-1,000 therms/month, 1001-10,000 therms/month and 24 usage over 10,000 therms/month. 25 Interruptible Sales Service Schedule 131 contains a 26 single rate per therm for all gas usage. The schedule also 27 has an annual minimum (deficiency) charge based on a usage Hirschkorn, Di 27 Avista Corporation 1 requirement of 250,000 therms per year. 2 Transportation Service Schedule 146 contains a $200 3 per month customer charge and contains a single rate per 4 therm for all gas usage.The schedule also has an annual 5 minimum (deficiency) charge based on a usage requirement of 6 250,000 therms per year. 7 Q.Where in your Exhibits do you show the present 8 and proposed rates for the Company's natural gas service 9 schedules? 10 A.Page 3 of Schedule 6 shows the present and 11 proposed rates under each of the rate schedules, including 12 all present rate adjustments (adders). Column (e) on that 13 page shows the proposed changes to the rates contained in 14 each of the schedules. 15 Q.You stated earlier in your testimony that the 16 Company is proposing an overall increase of 3.1% to the 17 rates of General Service Schedule 101.I s the Company 18 proposing an increase to the present basic / customer charge 19 of $4. OO/month under the schedule? 20 A.Yes.The Company is proposing to increase the 21 basic/customer charge from $4.00 to $4.25 per month. 22 Q.Why is the Company proposing an increase to the 23 basic charge? 24 A.The Company believes that the customer/basic 25 charge should recover a reasonable portion of the fixed 26 costs of providing service.The total fixed costs 27 associated with providing service to Schedule 101 customers Hirschkorn, Di 28 Avista Corporation 1 is several times the present monthly charge of $4.00. The 2 monthly cost associated with recovery of only the average 3 meter and service line for these customers is $6.03 per 4 month. 5 Q.What is the proposed increase to the rate per 6 ther- under Schedule 101 in order to achieve the total 7 proposed revenue increase for the Schedule? 8 A.The proposed increase to the energy rate under 9 the schedule is 3.512 cents per therm, as shown in column 10 (e), page 3, Schedule 6 of Exhibit No. 12. 11 Q.What would be the increase in a residential 12 customer's bill with average usage based on the proposed 13 increase for Schedule 101? 14 A.The increase for a residential customer using an 15 average of 66 therms of gas per month would be $2.56 per 16 month, or 3.2%.A bill for 66 therms per month would 17 increase from the present level of $79.38 to a proposed 18 level of $81.94, including all present rate adjustments. 19 Q.Could you please explain the proposed changes in 20 the rates for Large General Service Schedules 111? 21 A.Yes. The present rates for Schedules 101 and 111 22 provide guidance for customer placement:customers who 23 generally use less than 200 therms/month should be placed 24 on Schedule 101, customers who consistently use over 200 25 therms per month should be placed on Schedule 111.Not 26 only do the rates provide guidance for customer schedule 27 placement, they provide a reasonable classification of Hirschkorn, Di 29 Avista corporation 1 customers for analyzing the costs of providing service. 2 The proposed increase to the minimum charge for 3 Schedule 111 (for 200 therms or less) of $7.00 per month is 4 the sum of the Schedule 101 customer charge increase of 25 5 cents plus the proposed increase to the Schedule 101 rate 6 per therm of 3.512 cents multiplied by 192 therms.This 7 application maintains the present (breakeven) relationship 8 between the schedules, and will minimize customer shifting 9 between the Schedules.The remaining revenue requirement 10 for the Schedule is proposed to be recovered through a 11 uniform percentage increase of 2.5% to the remaining block 12 rates under the Schedule. 13 Q.How does the Company propose to recover the 14 increase of $7,000 to interruptible Service Schedule 131? 15 A.The Company proposes to increase to the usage 16 charge under the Schedule by 1.598 cents per thermo 17 Q.How does the Company propose to recover the 18 increase of $35,000 to Transportation Schedule 146? 19 A.The Company is proposing to increase the per 20 therm charge under the Schedule by 1.598 cents per thermo 21 Q.Is the Company proposing any other changes to its 22 natural gas service schedules? 23 A. No, it is not. 24 Q.Does that complete your pre-filed direct 25 testimony? 26 A. Yes, it does. Hirschkorn, Di 30 Avista Corporation cr) DAVID J.
