IPC-06- IDAHO POWER COMPANY DIRECT TESTIMONY CELESTE SCHWENDIMAN please state your name and business address. My name is Celeste Schwendiman and my business address is 1221 West Idaho Street, Boise, Idaho. By whom are you employed and in what capaci ty? I am employed by Idaho Power Company as a Senior Pricing Analyst in the pricing and Regulatory Services Department. Please describe your educational background. In 1993, I received a Bachelor of Arts in Psychology from Eastern Oregon Uni versi ty.In 1998, I attended the Center for Public Utili ties and National Association of Regulatory Utility Commissioners Practical Skills for a Changing Utility Environment conference. 2000, I received a Master s degree in Business Administration from Northwest Nazarene University, and in 2004, I attended the Edison Electric Institute I s Electric Rate Advanced Course. Please describe your work experience with Idaho Power Company. I became employed by Idaho Power Company in 1997 as a Research Assistant II in the pricing & Regulatory Services Department.I have been promoted as follows: February 1998, Entry Analyst; August 1998, Analyst; and July 2001, Senior Analyst.From 1998 through 2004, one of SCHWENDIMAN, DI Idaho Power Company my responsibilities was to assist in the preparation of the Power Cost Adjustment (PCA) filings.In 2005, I sponsored Additionally, I havetestimony in the Company s PCA filing. sponsored testimony in Case No. IPC-05-28, the general revenue requirement filing currently before the Idaho Public utili ties Commission. What is this year I s projection of PCA expense? The proj ection of PCA expense for the period April 1, 2006 through March 31, 2007 is $63,316,436.This amount is $37 600,023 less than the $100,916,459 normalized level of PCA expense that was included in the stipulation accepted by all of the parties in the Company s general The stipulationrevenue requirement Case No. IPC-05-28. is currently being considered by the Commission. What is the basis for the proj ection of April 1, 2006 through March 31 , 2007 PCA expense? The Commission, in Order No. 24806 issued in Case No. IPC-92-25, the proceeding which created the PCA, adopted a natural logarithmic function of proj ected April through July Brownlee reservoir inflow to compute the proj ection of April through March PCA expense.The equation was updated to be consistent with the stipulation.The present PCA regression equation is: SCHWENDlMAN, DI Idaho Power Company 137,165,252Annual PCA Expense $70,733, 339*ln (Brownlee inflow) $54,632,157 $1,004,538 $1, 900,000 This year s regression was based on the water years used in the calculation of the 2003 test year normalized power supply expense, updated with both costs and reduced power supply expense for the Bennett Mountain power plant as approved through Order No. 29790.Details of the regression equation are contained in Exhibit In this formula, the $1 137,165,252 is the constant that represents the prediction of annual net power supply expense that would occur if there was zero April through July Brownlee reservoir inflow.For each unit increase in the natural logarithm of the Brownlee reservoir inflow, the proj ection of annual power supply expense will be reduced by $70,733,339, the second of the constants in the equation $54,632,157 forabove.The other three constants: Qualifying Facilities (QF) purchase expense; $1,004,538 for the cloud seeding program expense; and the $1,900,000 for the associated benefit of the cloud seeding program, were updated consistent with the stipulation. What is the April through July Brownlee reservoir inflow forecast that you used to arrive at the SCHWENDlMAN, DI Idaho Power Company proj ection of PCA expense? The National Weather Service s Northwest River Forecast Center (NWRFC), in its official (final) April forecast, proj ected April through July Brownlee reservoir Inserting this valueinflow to be 8.38 million acre-feet. into the equation results in a projection of net PCA expense of $63,316,436 for the period April 1, 2006 through This amount is $37,600,023 less than theMarch 31, 2007. normalized level of PCA expense of $100,916,459.The forecast information supplied by the NWRFC is contained on Exhibi t 2. You have stated that the projected net PCA expense is less than the normalized level of PCA expense by What is the rate adjustment associated with$37 600,023. the proj ected decrease in PCA expense of $37 600,023 from the normalized level of PCA expense? The normalized PCA expense of $100,916,459, divided by the normalized system firm sales of 13,497,550 Megawatt-hours, is used to arrive at the normalized base power cost of 0.7477 cents per kilowatt-hour.For the period April 1, 2006 through March 31, 2007, the customer- level proj ected power cost of serving firm loads is 0.4691 cents per kilowatt-hour which is computed by dividing the projected net PCA expense of $63,316,436 by the 13,497 550 Megawatt-hours normalized system firm sales.The Company SCHWENDIMAN, DI Idaho Power Company adjusts its rates by 90 percent of the difference between the customer-level projected power cost of serving firm loads (0.4691 cents per kilowatt-hour) and the normalized base power cost (0.7477 cents per kilowatt-hour.Restated, this year I s computation is (.9) (0.4691- 0.7477) = negative 2507.The resulting adjustment is a 0.2507 cents per kilowatt-hour decrease from the normalized base power cost. Please describe the True-Up required from the comparison of the April 1, 2005 through March 31, 2006 actual results to last year 's proj ections. The Deferral Expense Account report for the April 1, 2005 through March 31, 2006 PCA year is attached as Exhibi t 3.This sheet compares the actual results to last year s proj ections, month by month , with the differences accumulated as the deferral balance.Interest has been applied to the balance monthly.The balance at the end of March 2006 was negative $39,513,704 as shown on Exhibit The Accounting Department has advised me that the deferral balance will be amortized during the current PCA year. What change has been made to the Deferral Expense Account report as a result of Order No. 29790? In Order No. 29790, the Commission approved recovery of Bennett Mountain power plant costs and required that the related reduction in power supply expense be included in the Company s 2006/2007 PCA.Row 54 of the SCHWENDlMAN, DI Idaho Power Company Exhibi t 3 reflects the reduction of power supply costs resulting from the Bennett Mountain Power plant as a monthly credi t. What change was made to the Deferral Expense Account report, in the 2005/2006 PCA filing as a result of Order No. 29600? As a result of Order No. 29600, which approved a settlement of specific 2004 general revenue requirement case issues, an adjustment to reflect the settlement of the disputed Valmy outage replacement power, and a non-recurring tax credit was added (row 53, This line item will provide a total credit ofExhibi t 3. $19.3 million to customers through a monthly adjustment of $804,167 over a 2-year term (June 2004 through May 2006. What change has been made as a result of Order No. 29789? In Order No. 29789, the Commission authorized the Company to collect $11 638,229, which was an estimated balance based on an $11,504,667 regulatory asset associated wi th income taxes with one year of in teres t .The Company used actual PCA year loads for June 2004 through March of 2005 and estimated April and May 2005 loads to calculate a PCA-year ending balance of $11 638,229 (row 28, Exhibit 4. Later , the Company adjusted the April and May loads to actual and reduced the June 1, 2005 beginning balance to SCHWENDlMAN, DI Idaho Power Company $11,592,035 (row 28, Exhibit 5) as a result of the difference between the estimate and actual loads for April This value, plus one year of interest wasand May. collected over the 2005/2006 PCA year.As of March 2006, all but $1 962,462 (row 20, Exhibit 6) was collected through rates.The Company has estimated that it will collect an additional $1.7 million in April and May of this year.The remaining balance (currently estimated at $300,681) will be adjusted based upon the actual April and May collection and added to the True-up of the True-up as a lump sum in June of 2006 and collected in the 2007/2008 PCAyear , through the 2007/2008 True-up of the True-up. Were there any other changes made to this year s PCA? The base constants in both the PCAYes. formula and the Deferral Expense Account report including normalized Idaho jurisdictional sales, and normalized system firm sales have been updated.These updates reflect the Company s general revenue requirement filing, Case No. IPC- 05-28 and resulting stipulation. What is this year s True-up rate? This year I s True-up component of the PCA the Deferral Expense Account report balance of negative $39,513,704 divided by the normalized Idaho jurisdictional sales of 12 695,163 which results in a rate of negative SCHWENDlMAN, DI Idaho Power Company 3113 cents per kilowatt-hour. What is this year I s True-up of the True- rate? The Company collected all but $24, 513,298 of the 2005/2006 PCA True-up balance (row 98, Exhibit 3. Dividing the $24,513,298 balance by the normalized Idaho jurisdictional sales of 12,695,163 Megawatt-hours results in 1931 cents per kilowatt-hour as the True-up of the True- rate. Why did the Company under-recover a significant portion of the True-up of the True-up? The True-up of the True-up included two non- tradi tional items.First, in response to the Company ' proposal in its 2005/2006 PCA filing, the Commission agreed that the Company should mitigate the impact of the below normal water year projected costs by delaying recovery of This was achieved by maintainingsome power supply expense. PCA rates at current levels.To hold the rate constant, $28.6 million was postponed for recovery in the 2006/2007 PCA year as part of the True-up of the True-up.Second, irrigation class lost revenues in the amount of $13. million were authorized for deferred recovery, through the PCA, by Commission Order No. 29669, and this balance was placed in the True-up of the True-up balance in May of 2005. The True-up of the True-up balance, including the SCHWENDIMAN, DI Idaho Power Company two items discussed above, waS offset throughout the 2005/2006 PCA year as a result of credits for intervener funding and fuel expense (Order No. 29793) and by PCA revenues. what is the PCA rate as a result of:1 ) the adjustment for the 2006/2007 projected power cost of serving firm loads, 2) the 2005/2006 True-Up portion of the PCA, and 3) the True-up of the True-up? The Company s PCA rate for the 2006/2007 PCA year is negative 0.3689 cents per kilowatt-hour.The rate is comprised of:1) the negative 0.2507 cents per kilowatt- hour adjustment for 2006/2007 projected power cost of serving firm loads, 2) the negative 0.3113 cents per kilowatt-hour for the 2005/2006 True-Up portion of the PCA, and 3) the 0.1931 cents per kilowatt-hour for the True-up of the True-up.The components used to calculate the negative 3689 cents per kilowatt-hour are shown in Exhibit 7 , the Company s proposed Schedule 55. How does the new PCA rate of negative 0.3689 cents per kilowatt-hour compare to the existing PCA rate? The 2006/2007 PCA rate of negative 0.3689 cents per kilowatt-hour is 0.9728 cents per kilowatt-hour less than the 0.6039 cents per kilowatt-hour PCA rate currently in place for all customers. What is the overall percentage decrease to SCHWENDlMAN, DI Idaho Power Company all customer classes, as a result of the 0.9728 cents per kilowatt-hour decrease? The overall percentage decrease is 19.34%, a total of $123.5 million dollars as shown in columns 5 and 8 of Exhibit The individual customer class decreases are also provided in Exhibit Does that conclude your testimony?

Tariff No. 101 Third Revised Sheet No. 55- Cancels Second Revised Sheet No, 55- Idaho Power Company SCHEDULE 55 POWER COST ADJUSTMENT APPLICABI LlTY This schedule is applicable to the electric energy delivered to all Idaho retail Customers served under the Company s schedules and Special Contracts. These loads are referred to as "firm" load for purposes of this schedule. BASE POWER COST The Base Power Cost of the Company s rates is computed by dividing the Company s power cost components by firm kWh load. The power cost components are the sum of fuel expense and purchased power expense (including purchases from cogeneration and small power producers), less the sum of off-system surplus sales revenue. The Base Power Cost is 0.7477 cents per kWh. PROJECTED POWER COST The Projected Power Cost is the Company estimate, expressed in cents per kWh , of the power cost components for the forecasted time period beginning April 1 each year and ending the following March 31. The Projected Power Cost is 0.4691 cents per kWh. TRU&UP AND TRU&UP OF THE TRU&UP The True-up is based upon the difference between the previous Projected Power Cost and the power costs actually incurred. The True-up of the True-up is the difference between the previous years approved True-Up revenues and actual revenues collected. The total True-up is (0.1182) cents per kWh. POWER COST ADJUSTMENT The Power Cost Adjustment is 90 percent of the difference between the Projected Power Cost and the Base Power Cost plus the True-ups. The monthly Power Cost Adjustment applied to the Energy rate of all metered schedules and Special Contracts is (0.3689) cents per kWh. The monthly Power Cost Adjustment applied to the per unit charges of the nonmetered schedules is the monthly estimated usage time (0.3689) cents per kWh. EXPIRATION The Power Cost Adjustment included on this schedule will expire May 31 2007. IDAHO Issued - April 12, 2006 Effective - June 1 , 2006 EXHIBIT NO. CASE NO. IPC-O6- C.
