Weather normalization reflects weather or temperature patterns which were measurably different than normal, as defined by using 30- year historical studies by the National Oceanic & Atmospheric Administration. Only residential and commercial sales are considered weather sensitive. Industrial sales are more sensitive to specific economic factors. ..,J Ta b l e 1 R e v e n u e Ro c k y M o u n t a i n P o w e r St a t e o f I d a h o Su m m a r y o f R e v e n u e A d j u s t m e n t s 12 M o n t h s E n d i n g S e p t e m b e r 2 0 0 S ($ O O O ' To t a l To t a l To t a l To t a l To t a l Bo o k e d No r m a l i z i n g Te m p e r a t u r e Ty p e 1 Ty p e 1 Ty p e 2 Ty p e 3 Ad j u s t e d Re v e n u e Ad j u s t m e n t s No r m a l i z a t i o n Ad j u s t m e n t s Ad j u s t e d Ad j u s t m e n t s Pr o f o r m a Re v e n u e Re v e n u e Ad j u s t m e n t Re s i d e n t i a l $2 4 80 3 $2 1 33 4 . 85 1 ($ 2 6 ) $2 1 30 9 $4 6 , I I I 34 1 $4 8 45 2 Co m m e r c i a l $2 2 02 9 40 7 . 43 6 ($ 4 9 ' 35 9 $2 3 38 8 32 0 $2 4 70 8 In d u s t r i a l $2 9 , 93 4 $1 2 43 8 . 29 9 $1 2 43 8 $4 2 37 3 86 8 $4 4 24 1 Pu b l i c S t & H w v $2 3 1 ($ 8 ($ 8 ' $2 2 3 $2 2 $2 4 6 Nu W e s t 91 5 ($ 4 ) ($ 4 91 1 $6 6 97 7 Mo n s a n t o - Fi r m 26 3 ($ 0 ) ($ 0 ) 26 3 26 3 Mo n s a n t o - No n F i r m $3 9 45 8 ($ 9 5 0 ) ($ 9 5 ( ) ) $3 8 50 7 $3 8 50 7 Mo n s a n t o C u r t a i l e d $7 2 6 $7 2 6 $7 2 6 $7 2 6 Mo n s a n t o - Su b t o t a l $4 1 72 1 ($ 2 2 4 ) ($ 2 2 4 ) $4 1 , 4 9 7 $4 1 , 4 9 7 To t a l I d a h o $1 2 2 63 3 $3 4 94 4 ($ 7 5 ) $3 4 87 0 $1 5 7 50 3 55 1 $6 6 $1 6 3 12 0 $0 . 00 1 So u r c e / F o r m u l a 30 5 F Ta b l e 3 Cu s t o m e r B+ C A+ D Ta b l e 3 Ta b l e 3 E+ F + G In f o . , Se r v i c e s I.

BPA began using the transfonner bank on January 1, 1999, but no payments were received by PacifiCorp until January 2005. Additional monthly payments have been received since that time. This adjustment removes the prior period payments so to only include an annual revenue amount of $233,057 for the test period. 2) The Company has contracts with Intennountain Power Agency and Deseret Generation and Transmission for use of the Mona substation. Because of contract disputes related to the use of this facility, several payments were posted to account 456 during the base year that relate to prior period usage. A regulatory adjustment is necessary to normalize the revenues related to this facility to the ongoing expected annual level. 3) This entry removes the Centralia gain from unadjusted results.

PAC-03-05) which allows PacifiCorp to defer for regulatory purposes and recover, through a surcharge, $4,198,000 for federal and state income tax payments made in 2002 and 2003, which resulted from the IRS income tax audit for the years 1994-1998. The surcharge became effective June 8, 2004. The $4 198,000 will be collected through this surcharge for a 16 month period ending September 15, 2005. In addition to the $4,198,000, $119,438 is also recovered on the same surcharge for deferred net power costs. Since a separate surcharge has been ordered, this adjustment removes all accounting entries that are included in the unadjusted data. The other related accounting entries are not included in the unadjusted data and do not require a regulatory adjustment. -..J \.., 'wi PacifiCorp Idaho General Rate Case September 2005 IRS Audit Deferrals Page 3.

To prevent non-participants from subsidizing this program, this adjustment removes any administrative and other expenses directly associated with the program from the test period. Note that the customer sales revenue is removed in adjustment 3.2. Costs shown above are direct program costs only that have fallen above-the-line and must be moved below- the-line.

Rocky Mountain Power Idaho General Rate Case Labor Escalation - September 2005 The base period (12 months ended September 2005), and the test period (proforma December 2006) labor expenses are summarized on page 4.12.2. The following is an explanation of the procedures used to develop the proforma labor expenses. 1. Actual September 2005 total labor related expenses are identified on page 4.12., including bare labor, incentive, other labor, pensions, benefits, and payroll taxes. 2. Actual September 2005 expenses for regular time, overtime, and premium pay were identified by labor group and annualized to reflect wage increases during the base period. These annualizations can be found on pages 4.12.3 and 4.12.4. 3. The annualized September 2005 regular time, overtime, and premium pay expenses were then escalated prospectively by labor group to December 2006 (see pages 4.12.4 to 4.12.7). Union costs were escalated using the contractual rates found on page 4.12.8. Non-union costs were escalated using budgeted merit increases also found on page 4.12. 4. Non-union incentive payments for the test period were provided by the Human Resource department and were calculated based on the fiscal year 2006, and 2007 budgets. 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. The budgeted incentive expenses can be found on page 4.12. 5. Proforma December 2006 pension and employee benefits expenses were provided by the Human Resource department based on the calendar year 2006 budget. These expenses can be found on page 4.12.2 and page 4.12.10. The proforma payroll tax calculations can be found on page 4.12., along with the wage amounts used in the calculation. 6. The December 2006 level of bare labor, incentive, other labor, pensions, benefits, and payroll tax expenses have been spread back to FERC accounts based on the percentages calculated using actual September 2005 expenses (see pages 4.12.13 through 4.12.15).

Notes: (1) This annualization adjustment is the severance expense associated with the rebasing initiatives. In June 2005, the Company booked a liability of $4 037 200. This adjustment removes this expense from results. (2) This adjustment removes a non-recurring entry that was included in the base year. (3) Account 502900 shows a total debit balance of $1,527 790 for the period 12 months ended Sept. 2005. The intemationaLassignee adjustment removes a credit of $44 402 from this account. The credit has also been removed in this adjustment to prevent a double count. \. - . - '- ' 'w i Es c a l a t i o n o f R e g u l a r , O v e r t i m e , a n d P r e m i u m l a b o r (F i g u r e s a r e i n T h o u s a n d s ) Ba s e P e r i o d : 1 2 M o n t h s E n d e d S e p t . 2 0 0 5 Te s t P e r i o d : 1 2 M o n t h s E n d e d D e c e m b e r 2 0 0 6 1i; O \1 ' ,, 5o o 1 ~ X Re ' rd i n a Tim e 29 . 1 0 4 30 , 94 2 04 2 2 , 35 , 74 6 92 7 33 , 03 9 35 3 88 3 16 1 33 7 38 9 , 53 2 5o o 2 X X ve l 1 l m e 15 5 33 7 74 1 23 5 46 7 51 3 55 0 50 6 38 2 92 7 83 2 46 . 42 2 5o o 3 X X em i u m P a 26 7 34 0 31 7 32 0 32 1 28 2 38 2 25 0 33 1 83 1 39 8 43 9 ~: : ~ ~ Gr a n d T o t a l 33 . 12 6 34 , 61 9 38 , 10 1 32 8 32 , 72 4 39 , 49 5 38 , 82 2 36 , 83 8 , 3 ! 1 , 1 9 0 37 , 09 6 38 . 48 6 39 , 60 8 Ra l . 12 . 2 O f f i c e r / E x e m p t 3 ' B E W 1 2 5 4 i B E W 6 5 9 5 U W U A 1 9 7 8 U W U A 1 2 7 W y o m i n g 9 I B E W 4 1 5 ( L ar a m i e 5 7 11 i B E W 5 7 P O 12 i B E W 5 7 P S 13 P C C C N o n .
