AVU-E-09-01 DIRECT TESTIMONY OF WILLIAM G. JOHNSON 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.What is the scope of your testimony in this 22 proceeding? 23 A.My testimony will 1) identify ànd explain the 24 proposed normalizing and pro forma adjustments to the 25 October 2007 through September 2008 test period power Johnson, Di 1 Avista Corporation 1 supply revenues and expenses, and 2) describe the proposed 2 changes to the Power Cost Adjustment (PCA) calculation 3 methodology and the new authorized level of power supply 4 expense for PCA calculation purposes and 3) describe how 5 the Company proposes to track the expense and revenue 6 associated with the Lancaster plant, which will become an 7 Avista utilities resource beginning January 1, 2010. 8 Q.Are you sponsoring any exhibits to be introduced 9 in this proceeding? 10 A.Yes.I am sponsoring Exhibit No.6, Schedules 1 11 through 4, which were prepared under my supervision and 12 direction. 13 Q.Are other company witnesses providing testimony 14 regarding issues you are addressing? 15 A.Yes.Company wi tness Mr.Kalich provides 16 detailed testimony on the AURORA model used by the Company 17 to develop short-term power purchase expense, fuel expense 18 and short-term power sales revenue included in my exhibits. 19 20 21 II. Pro Form Exense Adjustment Q.Please provide an overview of your pro forma 22 adjustment to power supply expense. 23 A. The pro forma adjustment to power supply expense 24 involves the determination of revenues and expenses based 25 on the generation and dispatch of Company resources and Johnson, Di 2 Avista Corporation 1 expected wholesale market power prices as determined by the 2 AURORA model simulation for the pro forma period under 3 normal weather and hydro generation conditions.In 4 addition, adjustments are made to reflect contract changes 5 between test period and the pro forma period.The table 6 below shows total net power supply expense during the test 7 period and the pro forma period.For information purposes 8 only, the power supply expense currently in rates, which is 9 based on a calendar 2009 pro forma period, is also shown. Power Supply Expense . (Not Including Directly Assigned Potlatch Purchase) Power Supply Expense in Current Base Rates (Calendar 2009 pro forma) System $17 4,849,000 Idaho Allocation Adjustment to Test Period $180,395,000 $27,64,000 $9,789,095 Actual Oct 07-Sep 08 Power Supply Expense July 2009 - June 2010 Pro forma Power Supply Expense $208,040,000 10 11 Increase from Expense in Current Rates $33,191,000 $11,752,933 The net effect of my adjustments to the test year 12 power supply expense is an increase of $27,645,000 13 ($208,040,000 - $180,395,000) on a system basis. The Idaho 14 allocation of this adjustment of $9,789,095 is incorporated 15 into the revenue requirement calculation for the Idaho 16 jurisdiction by Company witness Ms. Andrews. 17 The increase in power supply expense compared to the 18 pro forma level in current base rates is $33,191,000 19 (system) and $11,752,933 (Idaho allocation).The power Johnson, Di 3 Avista Corporation 1 supply expense in current base rates is based on a calendar 2 year 2009 pro forma. 3 Q.What are the major factors driving the increased 4 power supply exense in the pro form year over the level 5 of power supply expense currently in base rates? 6 7 8 A.The level of power supply expense currently in base rates is $174,849,000 (system numer).This expense level is based on a calendar 2009 pro forma period.This 9 compares to the proposed pro forma power supply expense of 10 $208,040,000, an increase of approximately $33.2 million on 11 a system basis and an Idaho allocation of approximately 12 $11.8 million. 13 This increase in pro forma power supply expense over 14 the expense currently in base rates is based on numerous 15 factors, primarily reduced hydro generation due to the 16 elimination of the rate mitigation adjustment included in 17 the last case and higher retail loads. 18 Pro forma retail loads are 22.7 aM higher than loads 19 that current rates are based on.The increased loads are 20 due to two factors. One is the natural increase in retail 21 loads of approximately 14.3 aMW. The other 8.4 aMW of load 22 increase is due to the reduction in potlatch generation. 23 Because Potlatch generation expense is directly assigned to 24 Idaho, the Potlatch load equivalent to their generation is 25 removed from system loads.The reduction in Potlatch Johnson, Di 4 Avista Corporation 1 generation has the effect of increasing system loads for 2 rate making purposes, while at the same time reducing the 3 Potlatch power purchase expense directly assigned to Idaho. 4 5 Hydro generation is also lower than the level in current base rates.Pro forma hydro generation is 533.3 6 aM compared to 563.1 aM in current base rates, a 7 reduction of 29.8 aM.This pro forma removes the 8 additional 26.5 aMW of hydro generation incorporated in 9 last year's general rate case as the "rate mitigation 10 adjustment." The remaining reduction in hydro generation is 11 due to the reduction in Mid Columia purchased hydro 12 generation resulting from the expiration of the Wanapum 13 contract in November 2009. 14 The table below shows the primary factors driving the 15 increase in power supply expense compared to the level in 16 current base rates.

PRO FORM POWER SUPPLY EXPENSE 4 Overview 5 Q.Please identify the specific power supply cost 6 items that are covered by your testimony and the total 7 adjustment being proposed. 8 A.Exhibit No.6, Schedule 1 identifies the power 9 supply expense and revenue items that fall within the scope 10 of my testimony.These revenue and expense items are 11 related to power purchases and sales, fuel expenses, 12 transmission expense, and other miscellaneous power supply 13 expenses and revenues. 14 Q.What is the basis for the adjustments to the test 15 period power supply revenues and expenses? Johnson, Di 6 Avista Corporation 1 A.The purpose of the adjustments to the test period 2 is to normalize power supply expenses for normal weather 3 and hydroelectric generation and to reflect known and 4 measurable changes for the pro forma period that rates will 5 be in effect.Adjustments are also made to reflect 6 contract changes from the test period to the pro forma 7 period. 8 The AURORA Model dispatches Company resources on an 9 hourly basis and calculates the level of generation from 10 the Company's thermal resources, fuel costs for thermal 11 resources, and the short-term purchases and sales necessary 12 to serve system requirements. 13 Q.Have any changes been made in the calculation of 14 pro form power supply costs from the last general rate 15 case? 16 A.Yes.The primary change made in this general 17 rate case is to include the actual term power and natural 18 gas transactions already entered into for delivery in the 19 20 pro forma period.Term transactions are monthly and quarterly transactions.This is done to more accurately 21 reflect the actual power supply expense the Company will 22 incur during the pro forma period. 23 As of Novemer 30, 2008 Avista had entered into 33 24 forward electric contracts and 8 forward natural gas 25 contracts for delivery in the pro forma period.The Johnson, Di 7 Avista Corporation 1 electric contracts include 15 physical purchases and 4 2 physical sales and 14 financial (fixed-for-floating swaps) 3 purchases.The natural gas transactions include 4 4 purchases and 4 sales. 5 The mechanics of including actual transactions in the 6 pro forma is to add the physical electric transactions as 7 resources and obligations in the AURORA model and include a 8 mark-to-model adjustment in the pro forma for the financial 9 electric and natural gas transactions. If the actual 10 transactions lower power supply expense (lower purchase 11 costs or higher sales revenue) as compared to the cost 12 produced by the AURORA model, then the lower cost is 13 included in the pro forma expense.If the actual 14 transactions increase power supply expense (higher purchase 15 costs or lower sales revenue) as compared to the cost 16 produced by the AURORA model, then the higher cost is 17 included in the pro forma expense. 18 The Company's hedging program layers in purchase and 19 sales transactions prior to the delivery period, and some 20 of the actual transactions were entered into during the 21 period of high forward prices during the middle of 2008. 22 Because prices have declined since July 2008, the overall 23 impact of the actual transactions is an increase in the pro 24 forma expense.The table below shows the impact of the 25 actual transactions in the pro forma. Overall, the actual Johnson, Di 8 Avista Corporation 1 transactions increase pro forma expense by $4,314,400 on a 2 system basis, $1,527,729 Idaho allocation, compared to what 3 expenses would be based solely on the AURORA model output. 4 Avista' s hedging strategy and risk management program are 5 explained in Mr. Storro' s testimony. Actual Electric and Natural Gas Transactions Impact on Proforma Power Supply Expense Term Transactions through 11-30-08 System Numbers Idaho A1loætion Physical Electric Transactions Mark to Market $43,304 $15,334 Financial Electric Transactions Mark to Market $2,923,297 $1,035,139 Natural Gas Transactions Mark to Market $1,347,800 $477,256 $4,314,400 $1,527,7296Total Proforma Impact of Actual Transactions 7 Detailed workpapers are provided for all the actual 8 transactions included in the pro forma. 9 Q. Are there any other changes in how the pro form in 10 this case was developed? 11 A.No. Other than including actual transactions and 12 the removal of the hydro rate mitigation adjustment, the 13 process to develop the pro forma net power supply expense 14 in this case is the same as in the 2008 general rate case. 15 A brief description of each adjustment is provided in 16 Exhibi t No.6, Schedule 2.Detailed workpapers have been 17 provided to the Commission coincident to this filing to 18 support each of the pro forma revenues and expenses.The 19 detailed workpapers for each adjustment show the actual Johnson, Di 9 Avista Corporation 1 revenue or expense in the test period, and the pro forma 2 revenue or expense. 3 Long-Term Contracts 4 Q.How are long-term power contracts included in 5 the pro form? 6 A.Long-term power contracts are included in the pro 7 forma by including the energy receipt or obligation 8 associated with the contract in the AURORA model and 9 including the cost or revenue in the pro forma net power 10 supply expense. 11 Q.Are there any new power purchases or sales in the 12 pro forma? 13 14 A.Yes.The Company entered into a two-year agreement to purchase generation from the Wells 15 hydroelectric plant that is assigned to the Colville Indian 16 Tribe, which I describe in more detail below.Also, the 17 purchase from Thompson River Cogen, a cogeneration plant in 18 Thompson Falls, Montana, that was included in the 2008 rate 19 case, was removed from this case because of the delays in 20 the start-up of the plant. 21 Q.Please describe the purchase of the Col ville 22 Indian Tribe's Well's generation output? 23 A.Avista entered into a two-year agreement 24 beginning October 2008 and ending September 2010 to 25 purchase the Colville Indian Tribe's 4.5% share of the Johnson, Di 10 Avista Corporation 1 output of the Wells hydroelectric generation. Prior to this 2 agreement, Avista purchased 3.34% of the Well's output at 3 actual production cost from the owner of Wells, Douglas 4 PUD.The additional 4.5% of Wells output assigned to the 5 Colville Indian Tribe was purchased through a competitive 6 auction at the market prices at the time. The purchase of 7 the Colville Indian Tribe's share of Wells output at market 8 prices is the reason for the increase in Well's cost in the 9 pro forma. 10 11 Q. Why is this purchase important to the Company? A.This purchase was important because of the 12 capacity and ancillary products that come with a Mid 13 Columia generation product.In addition to the energy, 14 Mid Columia generation has dYnamic capacity that the 15 Company uses for frequency regulation and load following. 16 The generation also comes with a "paper pond" that allows 17 the Company to shift generation from low load to high load 18 hours. 19 The amount of generation the Company has at the Mid 20 Columia is being reduced as the existing contracts with 21 Grant PUD expire and the amount of generation at Priest 22 Rapids (November 2005) and Wanapum (Novemer 2009) are 23 reduced by roughly half. The Wells purchase makes up for a 24 good portion of the loss of capacity at Priest Rapids and Johnson, Di 11 Avista Corporation 1 Wanapum, and allows the Company to maintain regulation 2 functions at the Mid Columia. 3 Short-Term Power Purchases and Sales 4 Q.How are short-term transactions included in the 5 pro form? 6 A.After including the actual short-term 7 transactions explained earlier as resources and obligations 8 in the AURORA model, the balance of the short-term electric 9 power purchases and sales are an output of the AURORA 10 model. The model calculates both the volumes and price of 11 short-term purchases and sales that balance the system's 12 generation and long-term purchases with retail load and 13 long-term obligations.The price of the short-term 14 transactions represents the price of spot market power as 15 determined by the AURORA model. 16 Therml Fuel Expense 17 Q.How are therml fuel expenses determined in the 18 pro form? 19 A.Thermal fuel expenses include Colstrip coal 20 costs, Kettle Falls wood waste costs and natural gas 21 expense for the Company's gas-fired resources including 22 Coyote Springs 2, Rathdrum, Northeast, Boulder Park, and 23 the Kettle Falls combustion turbine.Uni t coal cos ts at 24 Colstrip are based on the long-term coal supply and 25 transportation agreements. Unit wood fuel costs at Kettle Johnson, Di 12 Avista Corporation 1 Falls are based on multiple shorter-term contracts with 2 fuel suppliers and inventory.Total fuel costs for each 3 plant are based on the unit fuel cost and the plant's level 4 of generation as determined by the AURORA model.Exhibit 5 No.6, Schedule 3 shows the pro forma fuel costs by month 6 for each plant. Mr. Kalich provides details and supporting 7 workpapers regarding the fuel costs for the Company's 8 thermal plants. 9 Transmission Expense 10 Q. What changes in transmission expense are in the 11 pro form compared to the test year or the 2008 rate case? 12 13 A.There is almost no change in transmission expense.Transmission expense in the pro forma is $4,000 14 (system) higher than the test year actual expense and 15 $169,000 lower than the pro forma in the 2008 rate case. 16 Q.will there be additional transmission expense in 17 the pro form period that has not been included in this 18 case? 19 A.Yes, beginning January 1, 2010 the Company will 20 purchase 250 MW of BPA point-to-point transmission for the 21 Lancaster plant.The cost of this transmission will be 22 approximately $375,250 per month. The Company proposes to 23 track this expense in the PCA at 100 percent until such 24 time that this expense is included in base retail rates. 25 Johnson, Di 13 Avista Corporation 1 iv. PCA CALCULTIONS 2 Proposed Changes to the PCA 3 Q.Is the Company proposing any changes to the PCA 4 methodology? 5 6 A.Yes.The Company is proposing four changes to the PCA calculations.The first is to change the sharing 7 percentages between Customers and the Company from 90%/10% 8 9 to 95%/5%.The second change is to include third-party transmission expense (Accounts 565710 & 565000)and 10 transmission revenue (Accounts 456100, 456016 & 456700) in 11 the PCA.The third change is to use the average cost of 12 production/transmission included in base rates as the 13 retail revenue credit instead of the marginal cost of power 14 currently used in the PCA. The fourth change is to include 15 the Production Tax Credit in the PCA. 16 The Company is also proposing to include the expenses 17 and revenues related to the Lancaster plant in the PCA 18 beginning January 1, 2010, until the expense and revenue 19 related to the Lancaster plant are included in base rates. 20 Customer ¡Company Sharing 21 Q. Why is the Company proposing a change in the 22 sharing between customers and the Company in the PCA? 23 A.The primary reason to change the sharing 24 methodology is the increased volatility of power supply 25 costs. The increased volatility is driven primarily by two Johnson, Di 14 Avista Corporation 1 factors.One is the overall level of prices.Higher 2 prices mean greater absolute variability due to hydro 3 4 generation and load variations.Also important is the recent price volatility in the energy markets.For 5 example, actual prices varied from $88/MW in April 2008 6 when the Company was purchas ing energy due to low hydro 7 generation from the delayed run-off to $25/MW in June when 8 the hydro run-off materialized and the Company was selling 9 surplus power. This kind of price volatility coupled with 10 hydro variation can cause very large changes in the 11 Company's power supply expense.In April 2008 alone, the 12 Company's power supply expense exceeded the authorized 13 level by over $4.0 million (Idaho Allocation, over $14 14 million on a system basis), leading to a PCA deferral of 15 over $3.5 million, with the Company absorbing over 16 $400,000. 17 18 An additional volatility the Company faces is the price of natural gas.This is a significant source of 19 volatility with Coyote Springs 2 and will become even more 20 significant with the addition of Lancaster in 2010.A 21 rough rule of thum is that every $l/dth change in natural 22 gas prices changes Avista' s system power supply expense by 23 $10 million without the Lancaster plant.Natural gas 24 prices have varied by over $5/dth during 2008. This 25 variability caused by natural gas price will be even Johnson, Di 15 Avista Corporation 1 greater when the Company begins receiving power from the 2 Lancaster plant in 2010. 3 Transmission Exense and Revenue 4 Q.Why is the Company proposing to include 5 transmission expense and revenues in the PCA? 6 A.Transmission expense is a significant component 7 of the Company's overall power supply expense. While much 8 of the transmission is purchased under long-term contracts, 9 some is purchased on a short-term basis and is subj ect to 10 variabili ty in the expense level.Including transmission 11 expense in the PCA tracks the variability in this power 12 supply related expense. 13 Including transmission revenue in the PCA is a 14 fairness issue.if customers are absorbing the majority 15 of any increases in transmission expense then it is fair 16 that they receive the majority of increases in transmission 17 revenue. The transmission revenue the Company is proposing 18 to include in the PCA is the sale of Avista transmission to 19 third parties. 20 Including transmission revenues and expenses in the 21 PCA is also consistent with the Company's Retail Revenue 22 Credit proposal.The proposed Retail Revenue Credit 23 includes both the Production and Transmission components of 24 the retail rate. Johnson, Di 16 Avista Corporation 1 Finally, including transmission expense in the PCA is 2 necessary in order for the Company to include the expenses 3 associated with the Lancaster plant in the PCA. As stated 4 earlier in my testimony, beginning January 1, 2010, Avista 5 will be assigned 250 MW of BPA point-to-point transmission 6 from the Lancaster plant.This transmission is the only 7 means to move the power from the Lancaster plant to 8 9 Avista's system.The annual cost of this transmission is approxima tely $4.5 million or $375,250 per month. 10 Transmission expense must be included in the PCA in order 11 for the Company to recover all the costs associated with 12 the Lancaster plant. If the PCA is not modified to reflect 13 transmission expense in the PCA, then the Company proposes 14 that only the transmission expense for the Lancaster plant 15 be included in the PCA (at 100% of expense) until the costs 16 are included in base retail rates. 17 Retail Revenue Credit 18 Q.What change is the Company proposing to the 19 Retail Revenue Credit rate? 20 A.The Company proposes that the average cost of 21 production and transmission be used as the retail revenue 22 credit rate in the PCA.Currently, the retail revenue 23 credit rate is the marginal cost of power.The average 24 production and transmission cost represents the power 25 commodity component of retail rates and is the revenue Johnson, Di 17 Avista Corporation 1 collected from customers to recover power and transmission 2 costs.Using the average cost of production and 3 transmission as the retail revenue credit in the PCA 4 ensures that the actual revenue collected from customers 5 when retail sales increase is credited back against the 6 increased power supply expense and only the difference 7 between the actual cost of power and the amount of revenue 8 collected from customers is included in the PCA. 9 The average production cost also works equally well 10 when actual sales are lower than authorized sales. In that 11 case, actual power supply expense is lower because loads 12 are lower.The retail revenue credit adjusts for the 13 actual revenue the Company did not receive from customers. 14 The benefit of using the average cost of production 15 and transmission versus the marginal cost of power is that 16 the average cost of production works equitably for 17 customers and the Company when sales are both higher and 18 lower than the authorized level.As a note, the average 19 cost of production was used in the PCA for the months of 20 October 2008 through December 2008.Beginning January 21 2009, the retail revenue credit returned to being the 22 marginal cost of power. 23 Inclusion of Production Tax Credit in the PCA 24 Q.Please explain the Production Tax Credit and how 25 the Company proposes to include it in the PCA. Johnson, Di 18 Avista Corporation 1 A.The Production Tax Credit (PTC) is a Federal 2 income tax credi t the Company receives based on energy 3 production at the Kettle Falls bio-fuel plant and for 4 increased generation from upgrades at Cabinet Gorge dam. 5 The amount of PTe included in this case is a system amount 6 of $2,766,722, which lowers customer's rates. The PTC for 7 ratemaking purposes is grossed up to a revenue level of 8 $4.26 million (system) using the conversion rate of 65%, 9 which is one minus the federal income tax rate. The PTC is 10 set to expire for Kettle Falls on December 31, 2009. 11 Q.Why is it appropriate to include the PTC in the 12 peA? 13 A.The PTC is a credit that is directly tied to the 14 level of generation at Kettle Falls and Cabinet Gorge. The 15 credit is accrued monthly based on the level of generation 16 at Kettle Falls and Cabinet Gorge.It is very similar to 17 other power supply expenses, such as fuel expense, which is 18 directly related to the level of production, and included 19 in the PCA.Because it is directly tied to the level of 20 generation at Kettle Falls and Cabinet Gorge it is an 21 appropriate revenue item to include in the PCA. 22 As noted earlier, the Kettle Falls portion of the PTC 23 is set to expire on December 31, 2009.When the PTC 24 expires at the end of 2009, the PCA will properly account 25 for this change.By including the PTC in the PCA, Johnson, Di 19 Avista Corporation 1 customers will appropriately receive the full benefits from 2 the PTC through December 2009.If the PTC is not tracked 3 through the PCA, beginning January 2010 Avista would 4 inappropriately continue to flow a tax benefit to customers 5 that does not exist. 6 The Company proposes that Idaho's share of the system 7 PTC amount of $4.26 million be included in the authorized 8 level of power supply expense in the PCA, which would then 9 be compared with the actual PTC credit each month in the 10 actual power supply expense in the PCA.The differences 11 between the actual PTC and the authorized PTC will flow 12 through the PCA in the same manner as other power supply 13 expens es and revenues. 14 Inclusion of Lancaster Exense and Revenue in the PCA 15 Q.How does the eompany propose including the 16 expense and revenue related to the Lancaster plant in the 17 peA 18 19 A.Avista Utilities will begin purchasing the output of the Lancaster plant January 1, 2010.The Company 20 proposes that the expense and revenues related to the 21 Lancaster plant be included in the PCA until they are 22 reflected in base retail rates. 23 The Lancaster plant has several cost components. 24 Three cost components are part of the Lancaster power 25 purchase agreement and include a fixed capital payment, a Johnson, Di 20 Avista Corporation 1 fixed O&M payment and a variable O&M payment. All three of 2 these expenses will be recorded in Account 555, Purchased 3 Power Expense, which is an account tracked by the PCA. The 4 capital payment and the fixed O&M payment will be 5 relatively constant month to month, and the variable O&M 6 expense will be dependent on the amount of generation at 7 the plant. 8 Other Lancaster plant costs include natural gas fuel 9 expense and the natural gas pipeline transportation 10 expense, both of which are included in Account 547, Fuel 11 Expense, and the BPA transmission that is recorded in 12 Account 565, Transmission Expense.As explained earlier, 13 the Company is proposing in this filing that Transmission 14 Expense and Transmission Revenue be included in the PCA 15 calculation. 16 The Company is proposing that the fixed expenses 17 related to the Lancaster plant be isolated and tracked in 18 the PCA at 100% of the actual expense. The fixed expenses 19 include the capacity payment (capital payment and fixed O&M 20 payment), the natural gas pipeline transportation payment 21 and the BPA transmission payment. These fixed payments do 22 not vary and would otherwise be 100% included in base 23 rates. 24 The Company proposes that the variable expenses and 25 revenue from the Lancaster plant be included in the PCA in Johnson, Di 21 Avista Corporation 1 a manner similar to other expenses and revenues that would 2 3 be subject to the Company's proposed 95%/5% Customer /Company PCA sharing.The variable expenses 4 related to the Lancaster plant include the variable O&M 5 payment, natural gas fuel expense and the net impact of either reduced electrici ty purchases or increased6 7 electrici ty sales.Tracking the variable expense and 8 revenue in the PCA at the proposed 95%/5% sharing 9 arrangement is similar to how these expenses are tracked 10 for other resources. 11 New Authorized Power Supply and Transmission Exense 12 Q.What is the authorized power supply expense and 13 revenue proposed by the Company for the PCA? 14 15 A.The proposed authorized level of annual system power supply expense is $192,927,906.This is the sum of 16 Accounts 555 (Purchased Power), 501 (Thermal Fuel), 547 17 (Fuel), less Account 447 (Sale for Resale) . The proposed 18 level of Transmission Expense is $14,168,901. The proposed 19 level of Transmission Revenue is $9,478,694. 20 The level of retail sales MW and the retail revenue 21 credit will also be updated. The proposed authorized level 22 of retail sales to be used in the PCA is the July 2009 23 through June 2010 pro forma retail sales.The proposed 24 retail revenue credit is $47. 85/MW, which is the average 25 cost of production/transmission in this filing. Johnson, Di 22 Avista Corporation 1 The proposed authorized PCA expense and revenue is 2 shown in Exhibit 6, Schedule 4. 3 Q.Does that conclude your pre-filed direct 4 testimony? 5 A. Yes.
