ERRATA TO APPLICATION AND
DIRECT TESTIMONY OF PAWEL
P. GORALSKI

Idaho Power Company (“Idaho Power” or “Company”) hereby respectfully submits
to the Idaho Public Utilities Commission (“Commission”) this Errata to the Company’s
Application to implement Fixed Cost Adjustment (“FCA”) rates for electric service from
June 1, 2023 through May 31, 2024, and the Direct Testimony of Pawel P. Goralski
(“Goralski Testimony”) filed contemporaneously therewith on March 15, 2023, to ensure
accuracy, consistency, and clarity of the record as follows.
1. In the process of preparing the Power Cost Adjustment (“PCA”) filing, the
Company became aware of a minor variance between the forecast used in the FCA filed
ERRATA TO APPLICATION AND DIRECT TESTIMONAY OF PAWEL P. GORALSKI - 2
on March 15, 2023, and the forecast ultimately used in the PCA, which was filed on April
14, 2023. This discrepancy was due to an incorrect assignment of sales between the
Idaho and Oregon jurisdictions in the test year forecast used for the FCA filing.
2. Once the discrepancy was identified, the Company incorporated the
updated forecast into the FCA Rate Determination and Summary of Revenue Impact
provided as Exhibit Nos. 5 and 6 to the Goralski Testimony, respectively, and confirmed
that it did not result in a change to the FCA rate or the overall percentage revenue change.
More specifically, the revised versions of Exhibit Nos. 5 and 6, prepared by the Company
and provided with this Errata, demonstrate the test year update does not change the
proposed 2023-2024 FCA rates and the bill impact percentage is unchanged at a
decrease of 1.56 percent. Though there is a minor revenue impact of $196 less decrease
in billed revenue, from a filed overall decrease of $9,976,903, to a decrease of $9,976,707
based on the updated test year, this did not impact the percent change billed to billed.
3. Though not material to the Company’s Application or its request in this
proceeding, for the sake of clarity of the record the Company is providing revised versions
of Exhibit Nos. 5 and 6 with this Errata to replace Exhibit Nos. 5 and 6 filed with the
Goralski Testimony on March 15, 2023.
4. In addition, as a result of this update, the Company provides the following
substitutions to incorporate within the Application and the Goralski Testimony for
consistency and clarity as follows:
 Application, page 1, replace $9,976,903 with $9,976,707; and
 Goralski Testimony, page 4 (line 2) and page 18 (lines 1 and 25), replace
$9,976,903 with $9,976,707.
ERRATA TO APPLICATION AND DIRECT TESTIMONAY OF PAWEL P. GORALSKI - 3
These updates do not change anything else about the Application or the Goralski
Testimony.
DATED at Boise, Idaho, this 20th day of April 2023.
