On February 6, 2004, A vista Corporation dba A vista Utilities (A vista; Company)

increase its rates and charges for electric and natural gas service in the State of Idaho. The
Company in northern Idaho serves approximately 109 315 electric customers and 61 799 natural
gas customers. The Company s original request of $35.2 million or a 24.% increase in electric
revenue was revised at hearing to $31.1 million or 21.2%. The Company s original request of
$4.754 million or a 9.16% increase in natural gas revenue was revised at hearing to $4.06 million
or 7.8%. A proposed reduction in the Company s current Power Cost Adjustment (PCA)
surcharge rate was also requested. The net amount of actual increase varies by class of customer
and usage.

INTERLOCUTORY
ORDER NO. 29588
Company s PCA deferral account balance and authorizes an extended PCA recovery period. It is
the Commission s intention to issue a final Order with detailed reasoning within 30 days.
Commission Findings
The Commission has reviewed the filings of record in Case Nos. A VU-04-1 and
A VU-04-1 including the Prehearing Memorandum filed by Potlatch, the transcript of technical
proceedings, the transcript of public testimony and filed public comments, and the Petition for
Intervenor Funding filed by CAP AI.
Avista Utilities - Electric and Gas
Electric:
Regarding the Company electric operations, the Commission approves the
following for rate base and revenue requirement. We also make ultimate findings regarding
deferred PCA issues, Intervenor Funding and authorized changes in electric rates.
Rate Base
The Commission approves an electric pro forma rate base of$424 114 000.
Revenue Requirement
Current revenue recovered in electric base rates is $146 248 000. The Commission in
this case approves a base revenue requirement of $170 964 195, an increase in electric base rates
of $24 716 195 or 16.90%. The resultant average cents per kilowatt hour for base rates is 5.47
cents.
Power Cost Adjustment (PCA)
With respect to PCA issues deferred to this rate case in Order No. 29377 regarding
Coyote Springs 2 (CS2), the Commission notes an audited PCA account balance May 31 , 2004
of $26 261 334 (reference Case No. A VU-04-3), disallows CS2 Deal B losses of $6,496 669
and disallows $4 771 550 of Deal A losses for a net PCA account balance total of$14 993 115.
The Commission approves the Company proposal to recover the remaining PCA deferral balance
over a two-year period. The resultant annual PCA recovery is $7,496 558, subject to annual
PCA review and adjustment. The Commission authorizes a future change in the current uniform
percentage recovery method to a recovery method based on energy consumption.
The Commission in this Order also approves the assignment and recovery from the
residential class through the PCA of authorized CAP AI intervenor funding in the amount of
$12 622.75.
INTERLOCUTORY
ORDER NO. 29588
Electric Rates
The electric rates we approve as just and reasonable are set out in attached Schedule
A (Electric). Idaho Code 9 61-502. Base electric rates increase by $24 716 000 while PCA rates
decrease by $20 337 000. The result is a net increase of $4 379 000 or 2.5%. The authorized
revenue to be recovered in rates as set out below including residential exchange credit, Centralia
credit, PCA surcharge and DSM rider is $176 226 208 for a total average rate of 5.64 cents or
5%. We establish a separate rate schedule for Potlatch. The proposed increase for an electric
residential customer using an average of 941 kWhs per month is $4., or a 7.2% increase in
their electric bill.
Intervenor Funding
The Commission approves CAP AI's Petition for Intervenor Funding in the requested
amount of$12 622.75. Reference Idaho Code 9 61-617A. Our award is based on a finding that
CAP AI's participation materially contributed to the Commission s decision, the costs of
intervention are reasonable and would be a significant financial hardship for CAP AI if no award
is given, the recommendations made by CAP AI differed materially from Staff s case, and the
CAP AI's participation addressed issues of concern to residential and low income customers.
The award is to be recovered from residential customers through the Company PCA
mechanism.
Natural Gas:
Regarding A vista s natural gas operations the Commission approves the following for
rate base and revenue requirement. We also make ultimate findings regarding natural gas rate
base and authorized changes in natural gas rates.
Rate Base
The Commission approves a pro forma rate base of $59 653 000.
Revenue Requirement
The Commission approves additional natural gas revenues of $3 311 000 for a total
revenue requirement of $55 230 000, a 6.38% revenue increase.
Cost of Gas in Base Rates
The Commission adopts A vista s proposal to add the current PGA weighted average
cost of gas (W ACOG) adjustment of $0.27186/therm to base rates to produce a total base rate
gas cost of $0.44989/therm.
INTERLOCUTORY
ORDER NO. 29588
Natural Gas Rates
The natural gas rates the Commission approves as just and reasonable are those set
forth in attached Schedule B (Gas). Idaho Code 9 61-502. The base rates we approve in this
case are the fixed base rates incorporated in the Company s PGA adjustment authorized
simultaneously in Order No. 29590, Case No. A VU-04-2. The proposed increase for a natural
gas residential customer using an average of 73 therms of gas per month will be $12.84 per
month, or 21.39%.
CONCLUSIONS OF LAW
The Public Utilities Commission has jurisdiction over A vista Corporation dba A vista
Utilities and its Application in Case Nos. A VU-04-1 and A VU-04-1 pursuant to Idaho
Code, Title 61 and the Commission s Rules of Procedure, IDAPA 31.01.01.000 et seq.
