IDAHO POWER COMPANY’S
SECOND COMPLIANCE FILING

Idaho Power Company (“Idaho Power” or “Company”) hereby respectfully submits
this Second Compliance Filing to effectuate updates to the replacement Special Contract
for Electric Service between the Company and Micron Technology, Inc. (“Micron”) as
directed by the Idaho Public Utilities Commission (“Commission”) in Order Nos. 35735,
35482, and other relevant orders.
I. BACKGROUND
1. Micron is an existing retail customer of Idaho Power that has been taking
service pursuant to a special contract arrangement under Schedule 26 since 1995. On
March 9, 2022, Idaho Power and Micron entered into a revised Special Contract for

IDAHO POWER COMPANY’S SECOND COMPLIANCE FILING - 2
Electric Service, referred to herein as Electric Service Agreement (“ESA”), to replace the
then-existing Special Contract between the Parties that had been in effect since
December 29, 2009.
2. On March 10, 2022, Idaho Power filed an application with the Commission
seeking approval of: (1) the replacement Special Contract for Electric Service between
the Company and Micron dated March 9, 2022, and (2) the 20-year Power Purchase
Agreement (“PPA”) between the Company and Black Mesa Energy, LLC, which was
intended to facilitate the provision of energy under the revised Special Contract.
3. On August 1, 2022, the Commission issued Order No. 35482 approving the
Black Mesa PPA as filed but directing modifications to the ESA regarding the treatment
of Excess Generation Credits (“EGC”) and Renewable Capacity Credits (“RCC”). In
addition, the Commission addressed cost sharing under the Power Cost Adjustment,
finding “it fair, just, and reasonable, and consistent with the treatment of all of the
Company’s other similar NPSE, to subject the EGCs and RCCs in the Micron ESA to
95%/5% under the PCA.”1 Finally, the Commission determined that review and approval
of future renewable PPA or resource construction agreements was necessary to ensure
costs are not unfairly shifted to other customers.
4. In relation to the Commission’s directive that the Parties employ a new
method for calculating RCCs, Idaho Power filed a Petition seeking clarification on how to
calculate the RCCs under the Micron ESA, which resulted in the Commission directing
Idaho Power to work together with Commission Staff (“Staff”) “to develop a rate structure
for calculating Micron's RCC under the ESA,” to be submitted in a compliance filing.2

1 Order No. 35607 at 13.
2 Order No. 35532 at 10.

IDAHO POWER COMPANY’S SECOND COMPLIANCE FILING - 3
5. As directed by the Commission, Idaho Power and Staff worked together in
good faith to develop a performance-based compensation method for Micron RCC
payments, and as a result of those collaborative efforts, Idaho Power made a Compliance
Filing dated December 23, 2022, proposing to implement a Proposed Renewable
Capacity Credit Payment Performance Mechanism for calculating RCC under the Micron
ESA.
6. On April 12, 2023, the Commission issued Order No. 35735, approving the
Company’s Proposed Method for Calculating RCC payments under the Micron ESA and
directing the Company to update the ESA and Schedule 26 consistent with the
Commission’s findings in that Order and other relevant orders including Order No. 35482.
7. Thereafter, the Parties entered into the First Amendment to the ESA to
incorporate the direction from, and comply with, Commission Order Nos. 35735 and
35482.
II. COMPLIANCE - FIRST AMENDMENT TO ESA
8. The Company is now submitting this Second Compliance Filing to present
the First Amendment to the Micron ESA, which addresses the Commission-directed
modifications to the ESA and corrects an unintended omission from the replacement ESA
as more fully described below, as well as updated Schedule 26. The First Amendment
and Schedule 26 are attached hereto as Attachments 1 and 2, respectively.
Correction of Omission
9. In contemplating updates to the ESA as ordered by the Commission, the
Company became aware that the replacement ESA inadvertently omitted the final
sentence of Section 5.4, Excess Demand, which includes the annotation to the associated

IDAHO POWER COMPANY’S SECOND COMPLIANCE FILING - 4
component charge specified in Schedule 26, the “Daily Excess Demand Charge”; this
sentence is a standard provision in special contracts and was included in Micron’s 2009
ESA, but erroneously omitted from the replacement ESA.
10. As a result, the First Amendment provides for the following revision to
Section 5.4 of the ESA (new language is underlined):
5.4 Excess Demand. The availability of power in excess of the Contract
Demand is not guaranteed, and if Billing Demand at the Micron Facility
exceeds the Contract Demand, Idaho Power may curtail service to the
Micron Facility. Idaho Power reserves the right to install, at any time, at
Micron’s expense, any device necessary to protect Idaho Power’s system
from damage which may be caused by Billing Demand at the Micron Facility
exceeding the Contract Demand. Micron will be responsible for any
damages to Idaho Power’s system or damages to third parties resulting
from Billing Demand at the Micron Facility exceeding the Contract Demand.
Micron agrees to use its best reasonable efforts to monitor its electric loads
and to advise Idaho Power as soon as possible of the potential for Billing
Demands at the Micron Facility to exceed the Contract Demand. Billing
Demands in excess of the Contract Demand will be subject to the Daily
Excess Demand Charge specified in Schedule 26.
Updates to Pricing
11. The First Amendment provides for the replacement of ESA Exhibit 1,
“Pricing”, in its entirety with the revised version of Exhibit 1 (Revised Exhibit 1) provided
with the First Amendment, which addresses the modifications directed by the Commission
in Order No. 35482 and Order No. 35735 as follows.
12. Excess Generation Credits. In order to effectuate the Commission’s
directives related to the EGCs, Exhibit 1 has been revised to modify the definition of
“Excess Generation Price” to conform with Commission Order No. 35482, whereby it
ordered the Company to compensate Excess Generation at “the lower of the Excess
Generation Price (with the 85% adjustment) and the actual high or low load hour Mid-C

IDAHO POWER COMPANY’S SECOND COMPLIANCE FILING - 5
market price (without any adjustment) for each hour of excess energy delivered.3
13. Renewable Capacity Credits. Exhibit 1 of the ESA and Schedule 26 have
been modified to incorporate several revisions necessary to implement the Commission’s
orders. First, in Revised Exhibit 1, new definitions for “Annual Renewable Capacity
Credit,” and “Monthly Unadjusted Renewable Capacity Credit,” and “Performance Ratio
Adjustment Factor” have been added. One previously defined term (Renewable Capacity
Credit) has been renamed to “Monthly Adjusted Renewable Capacity Credit.” Finally,
Schedule 26 has been revised to align with the new/modified definitions contained within
Revised Exhibit 1 and a new table (Monthly Unadjusted Renewable Capacity Credit by
Month) has been included, consistent with the methodology presented in the Company’s
December 23, 2023 filing and approved by the Commission in Order No. 35735.
14. PCA Cost Sharing. In its order, the Commission found “it fair, just, and
reasonable, and consistent with the treatment of all of the Company’s other similar NPSE,
to subject the EGCs and RCCs in the Micron ESA to 95%/5% under the PCA.” The
Company understands the Commission will only allow recovery of 95 percent of the EGCs
and RCCs through amounts charged to PCA tracked accounts. In order to ensure the
Company remains indifferent to the negotiated ESA, Idaho Power and Micron have
agreed to modify Exhibit 1 of the ESA and Schedule 26 to include an “Administrative
Charge.” This charge will be recorded in Account 442221, Opr Rev Industrial-Micron Tech
and will not be subject to 95%/5% sharing under the PCA or any successor mechanism.

3 Order No. 35482 at 15.

IDAHO POWER COMPANY’S SECOND COMPLIANCE FILING - 6
III. COMPLIANCE – REVIEW OF FUTURE PPAs
15. In reviewing the Micron ESA and the associated Black Mesa PPA, the
question arose as to whether future renewable resource PPAs associated with special
contracts or energy services agreements required Commission review and approval.
16. Ultimately, the Commission determined that “that every future CEYW-CO4
project associated PPA agreement or resource construction agreement be first review
and approved by the Commission.”5 In conformity with the Commission’s directive, the
Company will file future renewable resource PPAs or similar resource construction
agreements with the Commission for its review and approval.
IV. CORRECTION OF THE RECORD
17. As it was developing the framework under which it will bill the new ESA and
related renewable elements, the Company became aware of a discrepancy between how
it described the way the Schedule 91, Energy Efficiency Rider (“Rider”) would be
assessed, and how the charge should be assessed according to its tariff. In its initial filing,
Company witness Aschenbrenner explained that the Rider charge will be “assessed
against all Idaho Power base rate charges assessed for Idaho Power-supplied energy
(inclusive of the Embedded Energy Fixed Cost Charge) contained within Schedule 26 net
of Renewable Resource credits” (emphasis added).6 However, this statement conflicts
with Schedule 91 itself, which states “the Monthly Charge is equal to the applicable
Energy Efficiency Rider percentage times the sum of the monthly billed charges for the
base rate components.”7 While there are no revisions necessary to the ESA or Schedule

5 Order No. 35482 at 17.
6 Aschenbrenner Direct at 19.
7 Tariff Schedule 91-1.

IDAHO POWER COMPANY’S SECOND COMPLIANCE FILING - 7
26 for the Company to apply the Rider in this manner, it wishes to bring the discrepancy
to the Commission’s attention in order to ensure the record is complete. The Company
will assess the Rider in accordance with Schedule 91. The Company has also spoken to
Micron representatives about the matter to ensure Micron understands how the Rider
charge will be assessed.
V. CONCLUSION
18. Idaho Power appreciates the Commission’s review and consideration of the
issues in this case and the opportunity to make this compliance filing to address the
Commission’s concerns. The Company believes the attached and executed First
Amendment makes the necessary changes to the ESA required to implement the
Commission’s directives and respectfully requests that the Commission approve: the
Micron ESA dated March 9, 2022; the First Amendment thereto dated May 31, 2023
including Revised Exhibit 1; and Schedule 26 as revised.
Respectfully submitted this 1st day of June 2023.
