Idaho Power Requests Rate
Decrease in Annual PCA Filing
Idaho Power has filed the Power Cost Adjustment(PCA),the
final piece of its annual spring cost adjustments with the Idaho
Public Utilities Commission(IPUC).As a net result of the PCA,
the Fixed Cost Adjustment(FCA),and an additional filing
related to relicensing the Hells Canyon Complex(HCC),all
Idaho customers will see a price decrease.
A typical Idaho residential customer using 950 kilowatt-
hours(kWh)per month will see an overall monthly
decrease of 8.26%,or approximately$9.97—the
combined impact of the following:
• The PCA calls for a decrease of$94.8 million,or 5.89%,for
Idaho customers.The PCA is a cost-recovery tool that passes
on both the benefits and costs of supplying energy to Idaho
Power customers.This year's PCA requests a monthly bill
decrease of$5.79 for the average Idaho residential customer.
• The annual FCA,filed March 14, requested a decrease of
$40.66 million.The FCA applies only to residential and small
commercial customers and adjusts prices based on changes
in energy use per customer during the previous year. For the
average Idaho residential customer,the FCA requested a
monthly bill decrease of$6.36.
• The HCC relicensing request,filed March 14,proposed an
increase of$29.7 million to recover ongoing financing costs
associated with the project. For the average Idaho residential
customer,the request would result in a monthly bill increase
of$2.18.
If approved as filed,this combined price decrease will
take effect June 1.The impact of these filings for all Idaho
customers is shown in the table below.The actual percentage
will depend on a customer's classification and the rate they pay.

The PCA has two main components:a balancing account
for power costs incurred the previous year and an estimate
of what energy will cost in the coming year.The balancing
account brings last year's anticipated costs in balance with
costs actually incurred the previous April through March.
The estimate reflects Idaho Power's anticipated fuel costs,
purchased power costs,and customer benefits from sales of
surplus energy for the coming April through March.
The decrease in this year's PCA is largely attributed to
the completed recovery of 2023 deferred power costs,
which was ordered by the IPUC to be recovered over two
years.Another contributing factor was increased sales of
renewable energy credits,which helps to offset power costs
for customers.
Neither Idaho Power nor its shareholders receive any
financial return from the PCA—money collected is used
to recover costs or credit benefits associated with annual
fluctuations in power costs.
