RE:PROPOSED SETTLEMENT OF PCA ISSUES AND IDAHO POWER'S MOTION
FOR ACCEPTANCE OF SETTLEMENT. CASE NO. IPC-03-
On August 2003 Idaho Power Company filed a Motion for Acceptance of Settlement
on behalf of itself, Commission Staff, the Industrial Customers ofldaho Power (ICIP), and the Idaho
Irrigation Pumpers Association (Irrigators). If approved by the Commission, the proposed settlement
would resolve the outstanding issues in this PCA docket.
PROCEDURAL BACKGROUND
On April 15, 2003, Idaho Power Company filed an Application to decrease its electric
rates under the annual Power Cost Adjustment (PCA) mechanism first approved by the Commission
in 1993. In Order No. 29243, the Commission approved the rates proposed in the Company
Application (with one adjustment) effective May 16, 2003 , subject to refund and interest. In
addition, the Commission set a prehearing conference to schedule six disputed issues valued at
approximately $5.1 million for evidentiary hearing. These six issues included: 1) pricing of real-time
transactions between Idaho Power and IDACORP Energy (IE); 2) recovery of IE- Tri State
Transmission costs; 3) Company sharing of the anticipated FERC settlement; 4) continuance of
payment for IE management contract benefits; 5) the proper amount of normalized energy to
compute the true-up rate; and 6) the proper amount of normalized energy to compute the rates to be
paid on PCA amounts deferred from the prior PCA period. Order No. 29243 at 10.
At the prehearing conference on May 2003 Idaho Power, Staff, the Irrigators, and
ICIP entered appearances. Although the Commission had intended to immediately set a date for

evidentiary hearing at the prehearing conference, the parties proposed an alternative with the hope
that an evidentiary hearing could be avoided.
To further explore the possibility of settlement and achieve a quicker resolution than may
be available through an evidentiary hearing, the Commission adopted the parties' proposal to move
the following four issues to Case No. IPC-01-16 for further proceedings: 1) pricing of real-time
transactions between Idaho Power and IE; 2) recovery of IE- Tri State Transmission costs; 3)
Company sharing of the anticipated FERC settlement; and 4) continuance of payment for IE
management contract benefits. Order No. 29258. Because real-time affiliate pricing, transmission
costs, and resolution of outstanding IE matters are already part of ongoing settlement discussions in
Case No. IPC-01-, the parties felt it would be more efficient to consolidate these issues under
that case number. The Commission directed the remaining two issues involving the proper amount
of normalized energy to calculate true-up and class deferral rates to continue under this case number
(IPC-03-5). Id.
PROPOSED SETTLEMENT
According to the Stipulation, the parties discussed three major issues. First, the parties
sought to determine the appropriate kWh sales level to use as the denominator for computing the
true-up rate for this case and future PCA periods. Second, Idaho Power proposed inclusion of a
symmetrical carrying charge on the unamortized balances during future true-up collection and refund
periods. The ICIP and Irrigators were also concerned that collection of their allocated true-up
amounts may be too great if 1993 normalized sales were used rather than the 2000 normalized sales
levels initially used to compute the deferral amount.
In the signed settlement document, all four parties agreed that:
1. The currently-approved PCA rates will remain in effect thru May 15 , 2004
, the remainder of this 2003-2004 PCA year.
2. The PCA methodology will be modified to include a true-up of the true-up.
At the time the Company makes its April 2004 PCA application, the
Company will compute the amount of any under-collection or over-collection
of the $38.7 million true-up amount approved by the Commission in Order
No. 29243. This amount will then be applied as a credit (or debit) against the
2004-2005 PCA ("True-Up of the True-). The approved PCA
methodology will thereafter include a True-Up of the True-Up for each
succeeding PCA year.
DECISION MEMORANDUM
3. Carrying charges on the unamortized balance at the rate of 2% per annum
(the currently approved rate for the true-up deferral balance accumulation)
will be included during the 2004-2005 . True-Up of the True-Up period.
Thereafter, carrying charges will be determined for either the true-up
collection period or true-up refund period, whichever occurs from year to
year. Idaho Power will compute the carrying charges using the same interest
rate the Commission annually determines to be appropriate for the true-up
deferral balance accumulation. The methodology for computing carrying
costs is more particularly described in Appendix 1 to the Settlement.
4. For Schedule 7, 19, and 24 customers, the True-Up of the True-Up will not
be applied to the $16 million total of class-specific adders from the 2002-
2003 PCA year. Instead, the customers in those classes will receive a credit
during the 2004-2005 PCA year which will be computed based on the
difference between the true-up rate credit computed under the currently-
approved PCA rate (using 1993 sales data) and the rate credit that would have
been computed using 2000 normalized kilowatt-hour sales for each of the
three classes. Attachment 2 to the Settlement describes this process in more
detail and shows the 2004-2005 rate credit on a cents per kilowatt-hour for
Schedule 7, 19 and 24 customers.
5. Beginning with the April 2004 PCA application, the Company will make its
annual PCA application utilizing its best estimate of the total Idaho
jurisdictional sales that will be made during the ensuing PCA year rather than
a sales constant set in a general revenue requirement case. The intent ofthis
change to the approved PCA methodology is to set a firm sales denominator
that will minimize the magnitude of subsequent True-Ups of the True-Up.
CO MMISSI ON D ECISI
Given that it has been signed by all the parties to this case, does the Commission wish to
approve the proposed settlement?
