Schedule 19 is an optional schedule, closed to new service, for commercial and industrial customers who have space heating, Some customers, depending upon their usage characteristics, could be receiving service on either schedule 6 or 23. In the normalization process we recalculate the schedule 19 customer's monthly bill applying schedules 6 and 23 rates to see if they would have billed cheaper on either one of these two schedules. This adjustment reflects the calculated reduction in revenue for those customers who would have billed cheaper on schedules 6 or 23. This adjustment also includes the annualization of the NuWest September 1 , 2006 price change that occurred during the test period.

However, the Company has profit centers in California, Oregon, Washington and Wyoming that cross state boundaries. This adjustment correctly assigns allocation factors by tax jurisdiction code rather than by profit center. (2) Also, this adjustment corrects the allocation code on several transactions where other electric revenues were assigned situs to individual states but should be assigned a system allocation code.

Rocky Mountain Power Idaho General Rate Case Labor Escalation- December 2006 The base period, 12 months ended December 2006, and the proforma period, 12 months ended December 2007, labor expenses are summarized on page 4.2. The following is an explanation of the procedures used to develop the proforma labor expenses. 1. Actual December 2006 total labor related expenses are identified on page 4., including bare labor, incentive, other labor, pensions, benefits, and payroll taxes. 2. Actual December 2006 expenses for regular time, overtime, and premium pay were identified by labor group and annualized to reflect wage increases during the base period (see pages 4.3 and 4.5.4). 3. The annualized December 2006 regular time, overtime, and premium pay expenses were then escalated prospectively by labor group to December 2007 (see pages 4.5.4 and 4.5). Union costs were escalated using the contractual rates found on page 4.6. Non-union costs were not escalated in 2007 because the increase will not be effective until December 26 2007. 4. Non-union incentive payments were provided by the Human Resources department and were calculated based on the calendar year 2007 projections. Union employees do not participate in the Company s annual incentive program; instead, they receive annual increases to their wages that are reflected in the escalation described above. 5. Proforma December 2007 pension and employee benefits expenses were provided by the Human Resource department. These expenses can be found on page 4.2 and page 4.8.

Refer to Order Nos. 29602 (AVU-04-01) and 29505 (IPC-03-13). The Company would prefer to include FA5 87 expense in rates, and does so for the other states it serves. However, given the Commission s direction in other cases, the Company has adjusted its expense to the level of cash contributions in the test year.

This adjustment removes the April through December 2005 portion of the March 2006 true-up from results, leaving the calendar year ended December 2006 in results. These true-ups were recorded as permanent differences, therefore there was no impact to deferred income tax expense, IDAHO REVISED PROTOCOL Page 8,0 Total Misc Rate Base Adjustments (Tab 8) TOTAL 8.4 Customer Cash Working Trapper Mine Rate Jim Bridger Mine Removal of Environmental Advances for Total Normalized Capital Base Rate Base Glenrock Mine Settlement Construction Operating Revenues: 2 General Business Revenues 3 Interdepartmental 4 Special Sales 5 Other Operating Revenues Total Operating Revenues Operating Expenses: 9 Steam Production 10 Nuclear Production 11 Hydro Production (19,193) 12 Olher Power Supply 13 Transmission 14 Distrtbution 15 Customer Accounting 16 Customer Service & Info 17 Sales 18 Administrative & General Total O&M Expenses (19 193) 20 Depreciation (44 750) 21 Amortization 876 22 Taxes Other Than Income 691) 23 Income Taxes: Federal 146 825) State (155 834) 25 Deferred Income Taxes 950 906 26 Investment Tax Credit Adj, 27 Misc Revenue & Expense Total Operating Expenses:(380 512) Operating Rev For Return:380 512 Rate Base: 33 Electric Plant In Service 023 248 431 740 766,323 (56 035) 34 Plant Held for Future Use (65,464) 35 Mise Deferred Debits 834 634 36 Elec Plant Acq Adj 37 Nuclear Fuel 38 Prepayments 39 Fuel Stock 285,414 40 Material & Supplies 41 Workin9 Capital 115,508 538 111 42 Weatherization Loans 43 Mise Rate Base Total Electric Plant 63,193,341 538 111 431 740 766 323 (56,035) Deductions: 47 Accum Prov For Depree 298 555 64,476 48 Accum Prov For Amort 49 Accum Def Income Tax (735 529) 50 Unamortized ITC 51 Customer Adv For Const (499 056)(499,058) 52 Customer Service Deposits 53 Miscellaneous Deductions 069 257)069 257) Total Deductions:005 289)64,476 069 257)(499,058) Totai Rate Base:188,051 538 111 431 740 766 323 441 (1,069 257)(499058) 60 Estimated ROE impact 282%-Q,041%-Q,O12%-Q,204%000%029%013% 64 TAX CALCULATION: 66 Operating Revenue 28,758 67 Other Deductions 68 Interest (AFUDC) 69 Interest 70 Schedule "M" Additions 627,487 71 Schedule .M" Deductions 088,723 72 Income Before Tax (3,432,478) 74 State Income Taxes (155 834) 76 Taxable Income 276 643) 78 Federal Income Taxes 146 825) IDAHO REVISED PROTOCOL Page 8,1 Total Misc Rate Base Adjustments (Tat TOTAL Centralia Powerdale Transmission Line Profoona Major Miscellaneous Upper Beaver Cove Hydro Hydroelectric Sale Plant Additions Rate Base Hydro Sale Decommission Facility Operating Revenues: 2 General Business Revenues 3 Interdepartmental 4 Special Sales 5 Other Operating Revenues Total Operating Revenues Operating Expenses: 9 Steam Production 10 Nuclear Production 11 Hydro Production 716)(121)(14 356) 12 Other Power Supply 13 Transmission 14 Distribution 15 Customer Accounting 16 Customer Service & Info 17 Sales 18 Administrative & General Total O&M Expenses 716)(121)(14 356) 20 Depreciation (163)015)(2,697)(36,876) 21 Amortization 36,876 22 Taxes Other Than Income (971)(720) 23 Income Taxes: Federal 156.434)575 182 796 State (157 140)486 161 652 25 Deferred Income Taxes 950 906 26 Investment Tax Credit Adj, 27 Misc Revenue & Expense Total Operating Expenses:(t01)(362 668)640)(2,196)(8,908) Operating Rev For Return:101 362 668 640 196 908 Rate Base: 33 Electric Plant In Service 346)790 974 (209 005)(87 128)(604 276) 34 Plant Held for Future Use (65.464) 35 Misc Deferred Debits 230 356 604,276 36 Elec Plant Acq Adj 37 Nuclear Fuel 38 Prepayments 39 Fuel Stock 285 414 40 Material & Supplies 41 Working Capital (422 603) 42 Weatherization Loans 43 Misc Rate Base Total Electric Piant:(9,346)52,790 974 027 706 (209 005)(87 128)(0) Deductions: 47 Accum Prov For Depree 286 102 856 125,935 48 Accum Prov For Amort 49 Accum Def Income Tax 262 (735 792) 50 Unamortized ITC 51 Customer Adv For Const 52 Customer Service Deposits 53 Miscellaneous Deductions Total Deductions:548 (735792)102 856 125 935 Total Rate Base:798)055 182 027 706 (106 147)808 (0) 60 Estimated ROE impact 000%095%-0,027%006%000%004%000% 64 TAX CALCULATION: 66 Operating Revenue 163 701 538 356 67 Other DeductionS 68 Interest (AFUDC) 69 Interest 70 Schedule "M.

Cash working capital is calculated by taking total operation and maintenance expense allocated to the jurisdiction (excluding depreciation and amortization) and adding its share of allocated taxes, including state and Federal income taxes and taxes other than income. This total is divided by the number of days in the year to determine the Company s adjusted daily cost of service. The daily cost of service is multiplied by net lag days to produce the adjusted cash working capital balance, Rocky Mountain Power Idaho Results of Operations December 2006 Trapper Mine Rate Base PAGE Adjustment to Rate Base: Mining Property Mining Property 399 399 175,642 (615,898) 559,744 IDAHO FACTOR FACTOR %ALLOCATED REF# 582%472 276 582%(40 536) 431 740 Below ACCOUNT TOTAL COMPANY Adjustment Detail: December 2005 Balance Calendar Year 2006 Change December 2006 Balance Average Balance December 2006 545 862 (740,440) 805,422 175,642 Calendar Year 2007 Change December 2007 Balance Average Balance December 2007 (491 356) 314 066 559,744 Description of Adjustment: PacifiCorp owns a 21.40% interest in the Trapper mine, which provides coal to the Craig generating plant. The normalized coal cost of Trapper includes all operating and maintenance costs but does not include a return on investment. This adjustment adds the Company portion of the Trapper mine plant investment to rate base. This investment is accounted for on the Company s books in FERC account 123.1 - Investment in Subsidiary Company. However, FERC account 123 is not normally a rate base account. This adjustment reflects net plant rather than the actual balance in FERC account 123 to recognize the depreciation of the investment over time.

The Companys investment in BCC is recorded on the books of Pacific Minerals, Inc (PMI), a wholly-owned subsidiary. Because of this ownership arrangement, the coal mine investment is not included in FERC account 101 -Electric Plant in Service. The normalized costs for BCC provide no return on investment. The return on investment for BCC is removed in the fuels credit which the Company has included as an offset to fuel prices leaving no return in results.

Adjustment to Property Tax: Taxes Other Than Income 408 (12 262)GPS 873%(720)11. Description of Adjustment: The Cove hydro electric plant was decommissioned in the fall of 2006. Most of the assets were retired and a few were transferred to other locations for use as capitalized spare parts. By December 31 2006, most assets that were going to be retired were, in fact retired. The powerhouse has not been retired as its ultimate disposition has not been determined. A few other assets were not retired until January 2007. Removal costs of about $3.3 million have been booked into the depreciation reserve and will be depreciated over the life of the remaining Bear River system assets. That depreciation will not begin until January 1 , 2008 at the earliest so is not adjusted here. This adjustment removes the Cove assets from calendar year 2006 results and also removes the associated expenses such as operation & maintenance, depreciation and property tax expense, etc incurred in calendar year 2006. This adjustment also adjusts the beginning/ending depreciation reserve balance for the removal costs to reflect the ongoing level which was on the books at December 31 2006, That part of the adjustment is noted by (1) above.
