SUBJECT: IDAHO POWER’S APPLICATION TO INCREASE ITS RATES TO
RECOVER ITS 2010 CASH CONTRIBUTION TO DEFINED BENEFIT
PENSION EXPENSE, CASE NO. IPC-E-10-08

On March 15, 2010, Idaho Power Company filed an Application for an order
approving an increase in rates, effective June 1, 2010, to allow recovery of the Company’s 2010
cash contribution to its defined benefit pension expenses. In February 2010, the Commission
issued Order No. 31003 directing the Company to establish a balancing account to track the
difference between cash amounts contributed to its pension plan and the amounts included in
rates. The Company’s Application states that its actuary has determined that a cash contribution
is necessary to its pension plan for the year beginning January 1, 2009. The Company expects
the contribution amount to be $5,822,145 as of September 15, 2010. The amount allocated to the
Idaho jurisdiction, minus a small reimbursement from a separate IDACORP subsidiary, is
$5,416,796.
Idaho Power’s Application seeks approval of $5,416,796 in pension cost recovery
over a one-year amortization period to allow recovery contemporaneous with the Company’s
2010 cash contributions to the defined benefit pension plan. The Company proposes to
proportionately divide the Idaho-allocated share of the 2010 cash pension payments by total
Idaho base revenues forecast for the period June 2010 through May 2011. The Company also
proposes to recover the 2010 contributions by an equal percentage rate applicable to all base
billing components within each customer class rate schedule. This approach results in a rate

increase of .77% for each class of customers served by Idaho Power. The Company’s proposed
revised tariff sheets are Attachment 1 to its Application.
The Company requests that its Application be processed by Modified Procedure.
Staff recommends that the Commission issue a Notice of Application and Notice of Modified
Procedure, establishing a comment period of 21 days, to process the Company’s Application for
a rate increase to allow recovery of the Company’s 2010 cash contribution to its defined benefit
pension expenses.
COMMISSION DECISION
Should the Commission issue a Notice of Application and Notice of Modified
Procedure to process Idaho Power’s Application, establishing a comment period of 21 days?
