AVU-E-08-01 DIRECT TESTIMONY OF WILLIAM G. JOHNSON FOR AVISTA CORPORATION (ELECTRIC ONLY) 1 2 I.INTRODUCTION Q.Please state your name, business address, and 3 present position with Avista Corporation. 4 A.My name is william G. Johnson.My business 5 address is 1411 East Mission Avenue, Spokane, Washington, 6 and I am employed by the Company as a Wholesale Marketing 7 Manager in the Energy Resources Department. 8 9 Q.What is your educational background? A.I graduated from the University of Montana in 10 1981 with a Bachelor of Arts Degree in Political 11 Science/Economics.I obtained a Master of Arts Degree in 12 Economics from the University of Montana in 1985. 13 Q.How long have you been employed by the Company 14 and what are your duties as a Wholesale Marketing Manager? 15 16 A.I started working for Avista in April 1990 as a Demand Side Resource Analyst.I joined the Energy 17 Resources Department as a Power Contracts Analyst in June 18 1996.My primary responsibilities involve power contract 19 origination and management and power supply regulatory 20 issues. 21 Q.Wht is the scope of your testimony in this 22 proceeding? 23 A.My testimony will 1) identify and explain the 24 proposed normalizing and pro forma adjustments to the 2007 25 test period power supply revenues and expenses, and 2) Johnson, Di 1 Avista Corporation 1 describe the new base level of power supply costs for Power 2 Cost Adjustment (PCA) calculation purposes, using the pro 3 forma costs proposed by the Company in this filing. 4 Q.Are you sponsoring any exhibits to be introduced 5 in this proceeding? 6 A.Yes.I am sponsoring Exhibit No.6, Schedules 1 7 through 4, which were prepared under my supervision and 8 direction. 9 Q.Are other company witnesses providing testimony 10 regarding issues you are addressing? 11 A.Yes.Company witness Mr.Kalich provides 12 detailed testimony on the AURORA model used by the Company 13 to develop short-term power purchase expense, fuel expense 14 and short-term power sales revenue included in my exhibits. 15 16 17 II. SUMY Q.Please provide an overview of your direct 18 testimony. 19 A.My testimony will identify and explain the 20 proposed normalizing and pro forma adjustments to the 2007 21 test period power supply revenues and expenses, and 22 describe the new base level of power supply costs for Power 23 Cost Adjustment (PCA) calculation purposes, using the pro 24 forma costs proposed by the Company in this filing.This 25 involves the determination of revenues and expenses based Johnson, Di 2 Avista Corporation 1 on the generation and dispatch of Company resources and 2 expected wholesale market power prices as determined by the 3 AURORA model simulation. In addition, adjustments are made 4 to reflect contract changes between the 2007 test period 5 and the 2009 pro forma period. The table below shows total 6 net power supply expense during the 2007 test period and 7 the proposed 2009 pro forma period.For information only 8 purposes, the power supply expense currently in rates, 9 10 11 12 13 14 15 16 17 18 which is based on a Septemer 2004 through August 2005 pro forma period, is also shown. ........ .. .. Powèr Supply Exp$. ot Including DJrectly Assigned Potlatch. Idaho AllocationSystem $82,643,000Power Supply Expense in Current Base Rates (Sep 04 - Aug 05 pro forma) Actual 2007 Power Supply Expense Adjustment to Test Period 2009 Pro forma Power Su I Ex ense $175,939,000 $971,000 $176,910,000 $343,831 The net effect of my adjustments to the 2007 test year is an increase of $971,000supplyexpensepower 19 ($176,910,000 - $175,939,000) on a system basis. The Idaho 20 allocation of this adjustment of $343,831 is incorporated 21 into the revenue requirement calculation for the Washington 22 jurisdiction by Company witness Ms. Andrews. 23 What are the major factors driving the increasedQ. 24 power supply expense in the pro form year over the level 25 of power supply exense currently in base rates? Johnson, Di 3 Avista Corporation 1 2 A.The level of power supply expense currently in base rates is $82,643,000 (system numer).This expense 3 level is based on a Septemer 2004 through August 2005 pro 4 5 forma period and 2002 retail loads.This compares to the proposed 2009 pro forma power supply expense of 6 $176,910,000, an increase of approximately $94.3 million on 7 a system basis and an Idaho allocation of approximately 8 $33.4 million. 9 This significant increase in pro forma power supply 10 expense over the expense currently in base rates is based 11 on numerous factors, including higher retail loads, reduced 12 hydro generation,increased fuel costs and increased 13 transmission expense. 14 15 Higher retail loads are the most significant factor contributing to higher power supply expense.Pro forma 16 retail loads are 128.6 aM higher than 2002 loads that 17 current rates are based on. Hydro generation is also lower 18 than the level in current base rates.Pro forma hydro 19 generation is 546.3 aMW compared to 553.1 aMW in current 20 base rates, a reduction of 6.8 aMW.The pro forma hydro 21 generation includes the uhydro rate mitigation adjustment" 22 of 26.5 aM.without the urate mitigation adjustment" 23 (described later in my testimony), the reduction in hydro 24 generation would be 33.3 aM.This reduction in hydro 25 generation is due to the reduction in Mid Coiumia Johnson, Di 4 Avista Corporation 1 purchased hydro generation resulting from the expiration of 2 the Priest Rapids contract in 2005 and the Wanapum contract 3 in 2009. .4 Fuel expense is significantly higher in the 2009 pro 5 forma compared to the fuel expense in current base rates. 6 Total thermal fuel expense for coal, wood fuel and natural 7 gas is approximately 50 percent higher on a dollars per MW 8 basis in the 2009 pro forma, increasing from $20.26 per MW 9 in current base rates to $30.33 per MW in the 2009 pro 10 forma. 11 Finally,transmission expense has increased by 12 approximately $2.9 million on a system basis, approximately 13 $1.0 million Idaho allocation.This is primarily due to 14 the purchase of an additional 125 MW of BPA point-to-point 15 transmission for Coyote Springs 2. 16 Q.What are the major factors driving the increased 17 power supply expense in the pro form year over the 2007 18 test year? 19 A.The primary factors increasing power supply 20 expense from the 2007 test year to the 2009 pro forma year 21 are the cost of serving additional retail load, fuel costs 22 and increased purchased power cos ts . 23 Retail loads in the 2009 pro forma period are 24 approximately 27 aMW higher than 2007 weather adjusted 25 retail load.Increased retail load creates higher power Johnson, Di 5 Avista Corporation 1 supply expense and also puts upward pressure on retail 2 rates because the marginal cost of power exceeds the 3 embedded cost of power.The increase in power supply 4 expense due to increased retail loads is approximately $4.8 5 million (Idaho allocation) . 6 In addition to higher loads, some of the. Company's 7 purchased power contract costs have increased, particularly 8 the Company's Mid-Columia purchases from the Priest Rapids 9 and Wanapum hydro generation developments.The cost for 10 the Company's share of Wanapum and Priest Rapids is 11 approximately $1. 7 million (Idaho allocation) higher in 12 2009 than in 2007.The Company's contract for Priest 13 Rapid's power expired October 31, 2005. While the Company 14 still gets power from Priest Rapids, the majority of the 15 power is now priced at market prices rather than the low 16 proj ect cost.The Wanapum contract expires October 31, 17 2009. Beginning November 1, 2009 the Company will receive 18 approximately half of much energy from these two plants as 19 before the expiration of the contracts, and only a small 20 portion of the power will be priced at project cost. Under 21 the new contract for these plants, the plant's owner, Grant 22 County PUD, gets more of the physical output of the plants 23 and also keeps more of the financial value of the 24 purchaser's share of the plants.Effectively, as Grant's 25 loads grow they keep some of the financial value of the Johnson, Di 6 Avista Corporation 1 purchasers' share of the plants in order to serve their 2 loads with proj ect cost power.Due to the very high load 3 growth in Grant County, less of the value of Priest Rapid's 4 power is going to the purchasers, and with the expiration 5 of the Wanapum contract in October 2009, less of the value 6 of that plant will go to the purchasers. 7 Finally, thermal fuel expense for Colstrip and Kettle 8 Falls has also increased significantly, increasing by 9 approximately $2.2 million (Idaho allocation) from 2007 to 10 2009. This is based primarily on increasing unit costs for 11 coal and wood fuel. 12 Q.Given the increased costs describe above, please 13 explain why there is almost no increase in the overall 14 power supply expense between the 2009 pro form year and 15 the 2007 test year. 16 A.The reason that the overall increase in power 17 supply expense from the 2007 year to the 2009 pro forma 18 year is very small is because the hydro generation urate 19 mitigation adjustment" offsets almost all of the increased 20 power supply expense.The hydro generation urate 21 mitigation adjustment", explained by Mr. Kalich, decreases 22 system power supply expense by approximately $12.8 23 (system), $4.5 million (Idaho allocation) . 24 After incorporating the urate mitigation adjustment", 25 the total power supply adjustment from 2007 actual to 2009 Johnson, Di 7 Avista Corporation 1 pro forma power supply expense is only $343,831 (Idaho 2 allocation), as shown in the previous table. 3 4 III. PRO FORM POWER SUPPLY COSTS 5 Overview 6 Q.Please identify the specific power supply cost 7 items that are covered by your testimony and the total 8 adjustment being proposed. 9 A.Exhibit No.6, Schedule 1 identifies the power 10 supply expense and revenue items that fall within the scope 11 of my testimony.These revenue and expense items are 12 related to power purchases and sales, fuel expenses, 13 transmission expense, and other miscellaneous power supply 14 expenses and revenues. 15 Q.What is the basis for the adjustments to the 2007 16 test period power supply revenues and expenses? 17 A.The purpose of the adjustments to the 2007 test 18 period is to normalize power supply expenses for normal 19 weather and hydroelectric generation and to reflect known 20 and measurable changes for the 2009 pro forma period that 21 rates will be in effect.Adjustments are also made to 22 reflect contract changes from 2007 to 2009. 23 The AURORA Model dispatches Company resources on an 24 hourly basis and calculates the level of generation from 25 the Company's thermal resources, fuel costs for thermal Johnson, Di 8 Avista Corporation 1 resources, and the short-term purchases and sales necessary 2 to serve system requirements. 3 Q.Have any changes been made in the calculation of 4 power supply costs from the prior general rate case? 5 A.Yes.The primary change made in this general 6 rate case is the use of loads that match the pro forma 7 period. The use of pro forma retail loads together wi th a 8 production property adjustment, provides a better matching 9 of revenues and expenses, and properly reflects the costs 10 of providing services to retail customers during the pro 11 forma period that rates will be in effect.Mr. Kalich 12 describes the pro forma retail loads used in this case, and 13 Company wi tness Ms. Knox explains the production property 14 adjustment. 15 The power supply pro forma in this case also includes 16 a urate mitigation adjustment" to hydroelectric generation 17 18 to decrease pro forma power supply expense.This adjustment increased hydro generation above normal 19 generation levels, which decreased power supply expense by 20 $12.8 million (system numer). This adjustment was made in 21 the AURORA model and is explained in Mr. Kalich' s 22 testimony. 23 Other than the use of pro forma retail loads and the 24 hydro rate mitigation adjustment, the process to develop Johnson, Di 9 Avista Corporation 1 the pro forma net power supply expense in this case is the 2 same as in the 2004 general rate case. 3 A brief description of each adjustment is provided in 4 Exhibit No.6, Schedule 2.Detailed workpapers have been 5 provided to the Commission coincident to this filing to 6 support each of the pro forma revenues and expenses.The 7 detailed workpapers for each adjustment show the actual 8 revenue or expense in 2007, and the pro forma revenue or 9 expense for 2009. 10 11 Long-Term Contracts 12 Q.How are long-term power contracts included in 13 the pro form? 14 A.Long-term power contracts are included in the pro 15 forma by including the energy receipt or obligation 16 associated with the contract in the AURORA model and 17 including the cost or revenue in the pro forma net power 18 supply expense. 19 Q.Are there any new power purchases or sales in the 20 pro form that were not in place during the 2007 test year? 21 A.Yes, there is one new long-term purchase.The 22 Company has entered into a 10-year purchase agreement with 23 Thompson River Cogen, a cogeneration plant in Thompson 24 Falls, Montana.The plant is expected to be on-line 25 sometime during early 2008 and produce approximately 11 Johnson, Di 10 Avista Corporation 1 average megawatts. The purchase price of $58.50 per MW is 2 very close to the forward power market prices in the AURORA 3 model for the 2009 pro forma period, so the contract has 4 minimal impact on power supply expense. 5 6 Short-Term Power Purchases and Sales 7 Q.How are short-term transactions included in the 8 pro form? 9 10 A.Short-term electric power purchases and sales are an output of the AURORA model.The model calculates both 11 the volumes and price of short-term purchases and sales that balance the system's generation and long-term12 13 purchases with retail load and long-term obligations.The 14 price of the short-term transactions represents the price 15 of spot market power as determined by the AURORA model. 16 17 Therml Fuel Expense 18 Q.How are therml fuel expenses determined in the 19 pro form? 20 A.Thermal fuel expenses include Colstrip coal 21 costs, Kettle Falls wood waste costs and natural gas 22 expense for the Company's gas-fired resources including 23 Coyote Springs 2, Rathdrum, Northeast, Boulder Park, and 24 the Kettle Falls combustion turbine.Uni t coal cos ts at 25 Colstrip are based on the long-term coal supply and Johnson, Di 11 Avista Corporation 1 transportation agreements. unit wood fuel costs at Kettle 2 Falls are based on multiple shorter-term contracts with 3 fuel suppliers and inventory.Total fuel costs for each 4 plant are based on the unit fuel cost and the plant's level 5 of generation as determined by the AURORA model.Exhibit 6 No.6, Schedule 3 shows the pro forma fuel costs by month 7 for each plant. Mr. Kalich provides details and supporting 8 workpapers regarding the fuel costs for the Company's 9 thermal plants. 10 11 Transmission Expense 12 Q. What changes in transmission expense are in the 13 2009 pro form compared to the actual 2007 transmission 14 expense? 15 A.Transmission expense in the 2009 pro forma is 16 approximately $.5 million (system) higher than the 2007 17 actual expense.The primary reason for this increase is 18 that beginning August 1, 2007 the Company began purchasing 19 an additional 50 MW of transmission for Coyote Springs 2 20 (CS2) . 21 Q.What is the change in transmission for CS2 22 between the 2007 test year and the 2009 pro form period? 23 A.Until August 1, 2007 the Company purchased 222 MW 24 of firm point-to-point (PTP) transmission from BPA and had 25 a 125 MW exchange agreement to meet the remaining Johnson, Di 12 Avista Corporation 1 transmission requirements for CS2. The exchange agreement 2 expired at the end of 2007.To meet the transmission 3 requirements of CS2 the Company purchased an additional 50 4 MW of firm PTP transmission from BPA, for a total of 272 MW 5 of firm transmission for CS2.This resul ts in total PTP 6 purchases of 468 MW (196 MW for Colstrip and 272 MW for 7 CS2) . 8 9 Q.Are there any new transmission contracts? A.Yes, there is a new transmission expense, labeled 10 Sagle-Northern Lights, for the purchase of transmission 11 from Northern Lights Utility to serve Avista customers in northern Idaho.This transmission purchase began May 1,12 13 2007.Purchasing transmission from Northern Lights was 14 less expensive then building what would have been a 15 duplicative transmission line. 16 17 18 iv. PCA CALCULTIONS Q.What effect will this case have on the PCA? 19 A.This case will update the authorized power supply 20 expenses and revenues, retail load, and the retail revenue 21 credit. PCA entries will continue to be calculated in the 22 same manner as current calculations.The final order in 23 this case will determine the new authorized level of power 24 supply expense, retail load and the retail revenue credit, Johnson, Di 13 Avista Corporation 1 and Potlatch generation and revenues used in the PCA 2 calculation. 3 Q. Wht is the authorized power supply expense and 4 sales proposed by the Company for the PCA? 5 6 A.The proposed authorized level of annual system power supply expense is $161,669,734.This is the sum of 7 Accounts 555 (Purchased Power), 501 (Thermal Fuel), 547 8 (Fuel), less Account 447 (Sale for Resale) in the Company's 9 filed pro forma. 10 11 The level of retail sales and the retail revenue credit will also be updated.Because the Company has 12 included a Production Property Adjustment in its revenue 13 requirement the proposed authorized level of retail sales 14 to be used in the PCA is the 2009 pro forma retail sales 15 Q.What value is the Company proposing as the retail 16 revenue credit in the PCA? 17 A.Because the Company is using pro forma retail 18 load to develop pro forma power supply expense, the Company 19 is proposing to use the marginal power cost from the AURORA 20 model as the value for the retail revenue credit in the 21 PCA.The proposed retail revenue credit is $53. 63/MW. 22 This is the average market purchases and sales price shown 23 on line 9 of Exhibit No.6, Schedule 3. This value is the 24 average market price for short-term transaction, which Johnson, Di 14 Avista Corporation 1 represents the marginal cost of power in the pro forma 2 period. 3 Absent the use of pro forma retail loads in the 4 development of power supply expense the Company would 5 propose that the correct value to use as the retail revenue 6 credi t in the PCA is the average production cost.The 7 average production cost represents the power commodity 8 component of retail rates and is the revenue collected from 9 cus tomers to recover power cos ts .Using the average cost 10 of production as the retail revenue credit in the PCA 11 ensures that the actual revenue collected from customers 12 when retail sales increase is credited back against the 13 increased power supply expense and only the difference 14 between the actual cost of power and the amount of revenue 15 collected from customers is included in the PCA. 16 The use of pro forma retail loads in the development 17 of power supply expense, however, makes the choice of what 18 value to use as the retail revenue credit less critical. 19 This is because the difference in actual sales and 20 authorized sales in 2009 is expected to be small since the 21 load is for the same year.The use of pro forma loads in 22 developing the pro forma power supply expense mitigates the 23 potential impact of load growth in the PCA. 24 25 The proposed PCA authorized monthly power supply expense,retail sales,and Potlatch generation that Johnson, Di 15 Avista Corporation 1 determines the Potlatch power purchase expense and revenue 2 related to the portion of Potlatch's load equal to their 3 generation is shown in Exhibit No.6, Schedule 4. 4 Q.Does that conclude your pre-filed direct 5 testimony? 6 A. Yes. Johnson, Di 16 Avista Corporation DAVID J. MEYER VICE PRESIDENT, GENERAL COUNSEL, GOVERNENTAL AFFAIRS AVISTA CORPORATION P.O.
