ORDER NO. 28931

YOU ARE HEREBY NOTIFIED that on January 7, 2002, PacifiCorp dba Utah
Power & Light Company (PacifiCorp; Company) filed an Application with the Idaho Public
Utilities Commission (Commission) requesting approval of the Company’s proposed electric
service schedules. Included in the Company’s filing is a related Cost-of-Service (COS) study, a
proposed Schedule 34-BPA Exchange Credit distribution, a proposed Power Cost Surcharge
($38 million) and a proposed Rate Mitigation Adjustment (RMA).
By this Notice the Commission proposes to process the Company’s request for
implementation of the Schedule 34-BPA Exchange Credit under Modified Procedure, i.e., by
written submission rather than by hearing. Reference Commission Rules of Procedure, IDAPA
31.01.01.201-204. The Commission finds the remainder of the Company’s Application to be of
such nature that the public interest requires a public hearing.
BACKGROUND
PacifiCorp in its Application represents that the Company’s Idaho revenue
requirement, rate design and class Cost-of-Service (COS) was last changed in 1991 in Case
No. UPL-E-90-1, Order No. 23508.

NOTICE OF MODIFIED PROCEDURE

ORDER NO. 28931 1
On November 2, 2000, the Company filed an Application in Idaho for approval to
defer excess net power costs incurred from November 1, 2000 through October 31, 2001.
Reference Case No. PAC-E-00-05. In Order No. 28630, the Commission approved the
Company’s request for deferred accounting of excess net power cost. Pursuant to that authority,
PacifiCorp reports that it has deferred approximately $37 million in excess net power costs
attributable to Idaho.
On November 5, 2001, the Company filed an Application for approval of a Power
Cost Adjustment (PCA) mechanism in Idaho. The Commission found the Company’s filing to
be incomplete and put the Company on notice that it must file supporting testimony as a
condition of any further procedural scheduling or consideration of the issues presented.
Reference Order No. 28904. The Company has yet to complete its filing.
In May 2001, PacifiCorp reports that it entered into a Settlement Agreement with the
Bonneville Power Administration (BPA Settlement) regarding the exchange benefits to be
provided by BPA through September 30, 2006 to qualifying residential and small farm
customers. The BPA Settlement, the Company contends, will provide approximately $34
million in benefits to Idaho customers in 2002.
COMPANY PROPOSAL
PacifiCorp’s proposal in this case consists of four elements:
1. Power Cost Surcharge
A surcharge would be added to the customers’ bills to recover the $38 million in
excess power costs incurred by the Company during the deferral period. This surcharge would
last over a two year period, with the level of the surcharge decreasing for the second year.
Under the Company’s proposed Power Cost Surcharge, the Company will recover
$38 million in excess power costs over a two-year period in which 70%, or $27 million, is
recovered in the first year and the remaining 30%, or $11 million is recovered in the second year.
This 70/30 split, the Company contends, is designed in conjunction with the Rate Mitigation
Adjustment to achieve the goal of customer classes not seeing any price increases as a result of
these changes in either year.
Because the excess power costs are energy related, the Company proposes to collect
them through a cents per kilowatt adjustment based on customers service voltage levels. The
NOTICE OF APPLICATION
NOTICE OF MODIFIED PROCEDURE

NOTICE OF INTERVENTION DEADLINE
ORDER NO. 28931 2
PCA rates are obtained by dividing the total excess power costs by the total kilowatt hours at the
generator and then adding an adjustment for voltage losses. The power cost surcharge will be
applied to all customer classes and to all energy usage.
2. Cost of Service—Rate Adjustment
In addition, the proposal includes adjusting rates by class to bring them closer to the
actual cost to serve each class. The adjustment, the Company contends, is a reapportionment of
the existing revenues and will not result in an increase of the revenues collected in total.
One significant change in the Company’s class Cost-of-Service study is a change in
the status of interruptible and other large special contract customers from system allocation to
state situs customers. This realignment comports with the Company’s Restructuring Proposal
pursuant to which each state electric company will have the obligation to serve all the retail load
in its service territory. If approved, there will be no interjurisdiction allocation of costs to which
system-wide revenue credits can be applied. Reference pending Case No. PAC-E-00-6.
The Cost-of-Service (COS) study presented is based on PacifiCorp’s year end March
2001 normalized results of operations for the State of Idaho. The Company proposes to redesign
its rates so that all customer classes fall within 5% of their cost of service. The cost of service
redesign will be fully implemented in the first year and has been designed, the Company
contends, to be revenue neutral; that is, the Company’s total revenues will be unchanged as a
result of this rate design.
3. Schedule 34—BPA Exchange Credit
The third aspect of the Company’s proposal is an increase in the Bonneville Power
Administration credit to the recently settled amount. The Bonneville Power Administration
(BPA) residential and small farm exchange credit is a mechanism to provide benefits to
qualifying customers of investor-owned utilities (like Utah Power) from the Federal Columbia
River Hydroelectric system and satisfaction of BPA’s obligations under the Northwest Power
Act of 1980. The credit is available only to residential and small farm customers and is provided
to the Company’s customers in Idaho through electric service Schedule No. 34. In recent years
the benefits have been allocated 43% to residential customers and 57% to irrigation customers.
The Company’s previous exchange agreement with BPA expired in 2001, and a new agreement
(the 2001 Settlement) was entered into to provide a continuation of exchange benefits. In its
NOTICE OF APPLICATION
NOTICE OF MODIFIED PROCEDURE
NOTICE OF COMMENT/PROTEST DEADLINE
NOTICE OF INTERVENTION DEADLINE
ORDER NO. 28931 3
2001 rate case, the Company reports that BPA proposed an alternative to the traditional
exchange. The alternative was to provide investor-owned utilities (IOUs) the option to purchase
actual power or rights to power through a subscription process. IOUs that chose subscription did
so as a settlement of their exchange rights for this period. The subscription was further split
between actual power and a monetary portion that was calculated as a difference between BPA’s
price and BPA’s forecasted market price. BPA expected that it would be required to purchase
additional resources in order to serve that portion of the subscription that was delivered as actual
power. Faced with the potential of very high costs for these additional resources, PacifiCorp
agreed to forego its right to actual power for an overall financial settlement of its exchange
benefits. The resulting financial BPA Settlement provides $34 million in benefits to qualifying
Idaho customers for the first year and $35.2 million in the second year. This level, the Company
reports, is substantially higher than historical levels. The Company proposes to allocate the
settlement amounts between qualifying residential and small farm (or irrigation) customers in the
same manner as the prior exchange agreement (i.e., 43% to residential customers and 57% to
irrigation customers).
PacifiCorp is requesting that the BPA credit be implemented immediately even if
other aspects of the filing are suspended. BPA increased its credit effective October 1, 2001.
PacifiCorp contends that it has a contractual obligation to pass the credit through to its customers
in a timely manner. Consequently, the Company is proposing that the Schedule 34 BPA credit,
be approved for a February 1, 2002 effective date.
PacifiCorp proposes to have the anticipated four months’ worth of accrued credit (for
the period from October 1, 2001 until the new credit level is implemented in rates) for residential
customers included in the first year’s credit rate. In other words, the rate for the first year will be
set to distribute 16 months worth of a normal year’s amount for residential customers. The total
amount of BPA credit the Company proposes to distribute to qualifying customers in year one is
$40.6 million. At the end of the first year, the rate will be reset to match a normal 12 months
worth of credit. The Company proposes no adjustment for the four-month lag for irrigation
customers. Irrigation usage, the Company contends, is largely completed by October 1.
Irrigation payments, the Company also contends, fluctuate significantly year-to-year due to
differences in irrigation usage during the irrigation season.

4. Rate Mitigation Adjustment (RMA)
Finally, the Company is proposing a rate mitigation adjustment. The rate mitigation
adjustment is a pricing mechanism that the Company proposes on a policy basis. The filing
consists of several elements that will each have the effect to increase or decrease individual
customer’s rates. The rate mitigation adjustment assures that when summed together no
customer class will receive a rate increase during the two year power cost amortization period
and those that qualify for the BPA credit will see a significant decrease.
The combination of the Cost-of-Service redesign, the Power Cost Surcharge and the
BPA credit, the Company contends, results in changes to most customer prices and in some cases
increases occur. The RMA is designed to offset those changes and to balance revenues so that
no customer class will see a price increase in the first two years. The RMA is also designed to
maintain greater price stability by minimizing price fluctuations from year to year.
The RMA is a surcharge or surcredit applied on a cents per kilowatt basis to each rate
schedule. It has been designed to mitigate and moderate price impacts that may occur and to
achieve the goal that customer classes receive no price increase for the next two years. In fact,
most customers will see significant price decreases in both year one and year two. In year one,
residential customers will see an average price decrease of 8%. Irrigation customers on average
will also see a price decrease of 8% while, overall, commercial and industrial customers will see
a decrease of 3%. Lighting customers will see an overall decrease of 9%.
In year two under the Company’s proposal, the residential customer class will see a
decrease of 15% from prices at the end of year one. Irrigation customers will also see an average
decrease of 15%, while commercial and industrial customers overall see a decrease of 4% from
prices in effect at the end of year one. Lighting customers overall will see a decrease of another
15%.
In the third year, the Company contends, prices will continue to decline. Residential
prices will decrease by 19%. The irrigators will see a decrease of 21% while commercial and
industrial customers will see, overall, a decrease of 6%. Lighting customers will see, overall, a
decrease of 17%. The following table summarizes these percentages.
