RE:CASE NO. PAC-02-5 (PacifiCorp)
CHANGE IN DEPRECIATION RATES-ELECTRIC PROPERTY
On October 1 , 2002, PacifiCorp dba Utah Power & Light Company (PacifiCorp;
Company) filed an Application for a change in its current depreciation rates applicable to
PacifiCorp s depreciable electric property. This change, the Company states, is for accounting
purposes only. PacifiCorp intends to seek approval of the requested changes for ratemaking
purposes in a future rate case. The accounting changes proposed by the Company are supported
by a Depreciation Study prepared by Deloitte & Touche, LLP and the pre-filed testimony of
three PacifiCorp witnesses. Pursuant to Idaho Code ~ 61-525, the Commission is empowered to
determine the property depreciation rates of property used to provide retail electric service. The
net effect of the Company s Application was to increase depreciation expense allocated to Idaho
by $0.6 million annually.
On May 7, 2003 Commission Staff and PacifiCorp filed a Stipulation, a Joint
Motion for Approval of Stipulation and separate letters in support of the Stipulation. The
Stipulation is offered as a compromise settlement of the issues raised in Case No. P AC-02-
Reference IDAPA 31.01.01.274. Should the Commission accept the proposed Settlement, the
depreciation expense currently booked by the Company will decrease approximately $0.
million annually. This is a $1.5 million difference in annual depreciation expense from the
Company s original request for an increase of$0.6 million.
On May 16, 2003, the Commission issued a Notice of Stipulation and Proposed
Settlement and Notice of Modified Procedure in Case No. PAC-02-05. The deadline for filing
DECISION MEMORANDUM
written comments or protests was May 30, 2003. The Commission Staff was the only party to
file comments. Staff, by way of comment, adopted its previous May 6, 2003 Letter of Support of
Stipulation and Proposed Settlement. Staff in its Letter of Support notes that it conducted an
analysis of the Company s filing and performed an audit of the physical plant located in Idaho.
Staff believes that the Settlement is a just and reasonable resolution of the depreciation issues
raised in the Company s filing and is fair to both the Company and its customers.
The consensus reached between the Staff and the Company imposes changes to the
Company s original proposal. A general description is set forth below:
1. The terminal net salvage value for steam production plant demolition will
be computed at the rate of $25.00/KW instead of the requested
$50.00/KW. This rate reflects the possibility of a sale of a steam
production plant at a book-value gain. While the sale is not likely, the
Company did acknowledge that it is possible.
2. Depreciation of water rights will cease as of April 1 , 2003.
3. Cost recovery for the Condit hydro plant shall be extended from 3.5 years
to a 7-year recovery period. This reduces the annual depreciation expense
and allows for more certainty to be achieved before accelerating the
depreciation.
4. Proposed depreciation expense for the Naches hydro plant will be removed
because the plant is subject to a pending sale.
5. Net salvage levels for various transmission and distribution plant accounts
will be changed.
6. It appears that all states are considering approval of the depreciation rates
for system assets as proposed by this settlement. By using the same rate in
all jurisdictions, the depreciation expense will be easier to calculate and
track.
In addition to the above changes, the Company agreed to immediately begin a process to
resolve the discrepancies identified by Staff between the continuing property records and the on-
site property records. The development and implementation of this accounting process will be
open to Staff for evaluation and input. It is vital that PacifiCorp improve its property records
Staff contends, before the Company seeks a rate increase including earning a return on those
assets. Staff recommends that the Commission require the Company to prepare a revised

accounting process and plan for implementation within 90 days. Finally, the Company agreed to
perform another depreciation study within the next five years.
Commission Decision
PacifiCorp in its Application requested a change in its depreciation rates. Tendered
for Commission consideration is a Stipulation and Proposed Settlement of issues raised in Case
No. PAC-02-Pursuant to Rule 276 of the Commission s Rules of Procedure, the
Commission is not bound by settlements.The Rules indicate that the Commission will
independently review any settlement proposed to determine whether the settlement is just, fair
and reasonable, in the public interest, or otherwise in accordance with law or regulatory policy.
Does the Commission continue to find it reasonable to process this case
pursuant to Modified Procedure?
Does the Commission find the proposed Settlement to be reasonable and in
the public interest?
Does the Commission find it reasonable to accept the Stipulation and
Proposed Settlement? If not, how does the Commission wish to proceed?
Staff recommends that the Company be directed to prepare a revised
accounting process reconciling its property records and present a plan for
implementation of same within 90 days. The Company believes that it can
comply with the proposed timeline. Does the Commission find Staffs
request to be reasonable?
