APPROVAL OF AMENDMENTS TO THE )
ENERGY SERVICES AGREEMENTS WITH ) APPLICATION
MICRON AND BRISBIE AND REQUEST )
FOR UPDATED PRICING ELEMENTS )
BASED ON 2023 IRP )
Idaho Power Company ("Idaho Power" or "Company"), in accordance with Idaho
Public Utilities Commissions ("Commission") Rule of Procedure' 52 and Idaho Code
§§ 61-502 and 61-503, hereby respectfully applies to the Commission for an order
approving: (1) the Second Amendment to the Brisbie, LLC ("Brisbie") Special Contract
and the Third Amendment to the Micron Technology, Inc. ("Micron") Special Contract; (2)
updated pricing elements for all Clean Energy Your Way ("CEYW") Renewable
Hereinafter cited as RP.
APPLICATION - 1

Construction Agreements that rely on inputs based on the Company's 2023 Integrated
Resource Plan ("IRP"); (3) associated revisions to Brisbie Schedule 33, Micron Schedule
26, and Clean Energy Your Way Program Schedule 62 ("Schedule 62"); and (4) the
Company's proposed method for future updates to pricing elements of contracts under
the Company's CEYW-Construction Program that rely on IRP data. In support of this
Application, Idaho Power represents as follows:
I. BACKGROUND
Case No. IPC-E-21-40— Clean Energy Your Way-Construction
1. On December 2, 2021, the Company applied to the Commission for
authority to expand its optional clean energy offerings through Schedule 62 under the
new CEYW name, including, in pertinent part, providing a tailored renewables option to
the Company's largest customers (Special Contract and Schedule 19, Large Power
Service) named CEYW-Construction. That option, which provided a framework for
offering large customers a tailored way to cover up to 110 percent of their energy use with
a renewable resource, was authorized by the Commission subject to certain additional
requirements, in Order No. 35893 issued on August 15, 2023.
Case No. IPC-E-21-42— Brisbie Special Contract
2. On December 22, 2021, Idaho Power filed an application seeking approval
of a Special Contract with Brisbie and associated tariff Schedule 33. The Special Contract
between Brisbie and Idaho Power may be referred to herein as the Brisbie Special
Contract or as the Brisbie Energy Services Agreement ("ESA").
3. Brisbie, in addition to its large load service requirements in excess of 20
megawatts ("MW"), has a sustainability objective to support 100 percent of its operations
APPLICATION - 2

with new renewable resources. Accordingly, the Brisbie Special Contract encompasses
the pricing associated with retail electric service from Idaho Power, cost and credit
components associated with new renewable resources to support Brisbie's load, and
terms and conditions governing the structure of this new arrangement, including
provisions that will hold other Idaho Power customers harmless. The Brisbie Special
Contract is consistent with and reflects the regulatory framework set forth in the CEYW-
Construction offering and was the first representation of that offering.
4. On October 27, 2022, Idaho Power and Pleasant Valley Solar ("Pleasant
Valley") entered into a Power Purchase Agreement ("PPA") for the sale and purchase of
200 megawatts ("MW") of renewable solar generation for a term of 20 years from the
scheduled Commercial Operation Date ("COD"), scheduled to be March 2025. In its
application filed November 14, 2022 (IPC-E-22-29), Idaho Power represented that all
costs associated with the Pleasant Valley PPA would be paid for by Brisbie, which was
consistent with the Brisbie ESA that was at the time undergoing Commission review. On
April 12, 2023, the Commission approved the PPA between Idaho Power and Pleasant
Valley.
5. On May 11, 2023, the Commission issued Order No. 35777 approving the
Brisbie Special Contract contingent on the parties modifying the ESA and Schedule 33
as directed by the Commission. The modifications required by the Commission for the
Brisbie ESA mirror those directed by the Commission for the similarly situated Micron
ESA regarding the treatment of CEYW-Construction pricing elements, including Excess
Generation Credits ("EGC") and Renewable Capacity Credits ("RCC"), and the Company
2 See, e.g., id., Order Nos. 35482 (Aug. 1, 2022), 35607 (Nov. 23, 2022), and 35735 (Apr. 12, 2023).
APPLICATION - 3

was instructed to file updated versions of the Brisbie ESA and Schedule 33 incorporating
the necessary modifications.
6. First Amendment to the Brisbie Special Contract. Thereafter, the Parties
entered into the First Amendment to the Brisbie Special Contract, dated August 3, 2023,
to revise Exhibit 3.1: Pricing, which sets forth the various rate component monthly charges
and pricing under the Special Contract, to incorporate the direction from, and comply with,
Commission Order No. 35777, and submitted the same for the Commission's approval.
On October 12, 2023, the Commission approved the First Amendment to the Brisbie
Special Contract, including Revised Exhibit 3.1: Pricing and revised Schedule 33.
7. On December 5, 2023, Idaho Power entered into an additional 20-year PPA
for the sale and purchase of 125 MW of renewable solar generation from Pleasant Valley
Solar 2 ("PVS2") with a COD of December 31, 2026. In its application filed January 3,
2024 (IPC-E-24-01), Idaho Power indicated it entered into the PVS2 PPA with Pleasant
Valley with the expectation of assigning the associated energy and environmental
attributes to Brisbie under the provisions contained in the approved Brisbie Special
Contract. On May 28, 2024, the Commission approved the Company's application for
approval of the PVS2 PPA.
Case No. IPC-E-22-06— Micron Special Contract
8. On March 9, 2022, Idaho Power and Micron entered into a revised Special
Contract, to replace the then-existing ESA that had been in effect since December 29,
2009. Like the Brisbie ESA, the Micron Special Contract contains CEYW-Construction
provisions by which Idaho Power will procure or construct, on Micron's behalf, renewable
resources to assist Micron in supporting a portion of its annual energy requirements with
APPLICATION -4

renewable energy generated by those resources—consistent with the structure of CEYW-
Construction. Idaho Power filed the Micron Special Contract and associated tariff
Schedule 26 for Commission approval on March 10, 2022.
9. On August 1, 2022, the Commission approved the Micron Special Contract
and Schedule 26 with specific modifications as directed in Order No. 35482 relating to the
treatment of EGCs, RCCs, and cost sharing under the Power Cost Adjustment (as defined
in Idaho Power's tariff on file with the Commission). As directed by the Commission,
Idaho Power worked collaboratively with Commission Staff ("Staff") on the rate structure
for Micron's RCC payments. The Commission issued Order No. 35735 on April 12, 2023,
approving the method proposed by Idaho Power in its First Compliance Filing with the
Commission dated December 23, 2022.
10. In Order No. 35482, the Commission also approved a 20-year PPA between
the Company and Black Mesa Energy, LLC ("Black Mesa") to facilitate the provision of
energy to the Company by a 40 MW solar resource under the Micron ESA. The Black
Mesa solar resource achieved its COD in June 2023 and has been providing energy to
Idaho Power's system under the terms of the Micron ESA since that time. As anticipated,
there has been no Excess Generation that has resulted from the project.
11. First Amendment to the Micron Special Contract. Subsequently, Idaho
Power and Micron entered into the First Amendment to the Micron Special Contract,
dated May 31, 2023, in pertinent part to revise Exhibit 1 — Pricing, which sets forth the
various rate component monthly charges and pricing under the Special Contract, to
address the modifications required by the Commission and submitted the same for the
Commission's approval. On August 23, 2023, the Commission issued Final Order No.
APPLICATION - 5

35898, approving the First Amendment to the Micron Special Contract including Revised
Exhibit 1 and revised Schedule 26.
12. Second Amendment to the Micron Special Contract. On October 27, 2023,
the Company and Micron entered into a Second Amendment to the Micron Special
Contract to extend the annual deadline for retiring environmental attributes connected
with project output from January 31 to March 1 because of the logistics of retiring such
attributes. The Second Amendment to the Micron Special Contract was approved by the
Commission in Final Order No. 36068 issued on January 24, 2024.
Case No. IPC-E-23-23— 2023 IRP
13. On September 29, 2023, Idaho Power filed an application seeking
acknowledgement of its 2023 IRP. In its application, the Company maintains that a
fundamental goal of the IRP process is to identify an optimal, or preferred, resource
portfolio. The 2023 preferred portfolio identifies resource options and timing to allow Idaho
Power to continue to reliably serve customer demand, balancing cost and risk over the
2024 to 2043 planning period.
14. Staff filed comments on February 15, 2024, and the Company filed reply
comments on February 29, 2024. As of the date of this application, the Commission has
not issued an order in the matter.
Case No. IPC-E-24-18— City of Boise CEYW Agreement
15. On April 23, 2024, Idaho Power filed an application seeking approval of a
CEYW Renewable Construction Agreement (as well as the First Amendment thereto)with
the City of Boise City ("City of Boise") which, if approved, authorizes the City of Boise to
secure up to 10 MW from the existing Black Mesa PPA ("City of Boise CEYW
APPLICATION - 6

Agreement"). In the application filed in that matter, the Company requests Commission
approval to commence the City of Boise CEYW Agreement beginning September 1, 2024.
II. THE PROPOSED AMENDMENTS
16. Based on the Commission's guidance related to the CEYW-Construction
offering, and as a result of the collaborative efforts undertaken by Staff and the Company
to fulfill the Commission's directives, the Company continues to refine the framework for
the ongoing implementation and administration of the CEYW-Construction offering.
17. To this end, the Company recently identified an opportunity to ensure the
review and updating of the pricing elements of CEYW-Construction agreements are
transparent, efficient, and consistent with Commission expectations prior to
implementation. The amendments also seek to reference the most currently available
data for CEYW-Construction pricing components by relying on the most recently filed IRP
rather than the most recently acknowledged IRP. After conferring with Staff, the Company
worked with Brisbie and Micron to amend their special contracts to incorporate language
that would provide for necessary flexibility in administering the ESAs, while ensuring that
changes in rates are considered in a separate proceeding.3 The amendments are
described more fully as follows.
Second Amendment to the Brisbie Special Contract
18. The Second Amendment to the Brisbie Special Contract dated March 14,
2024, provides for replacing Revised Exhibit 3.1: Pricing to the Special Contract in its
entirety with the Second Revised Exhibit 3.1, which sets forth the details of all rate
3 The Company also negotiated an amendment with the City of Boise to reflect the same definitions for
"Excess Generation Price" and "Mid-Columbia Forecast"that is contained in the Brisbie and Micron
amendments. That City of Boise CEYW Agreement and the associated contract amendment is
undergoing Commission review in Case No. IPC-E-24-18.
APPLICATION - 7

components and pricing under the Brisbie Special Contract, to incorporate language for
clarity and to provide for necessary flexibility in administering the Agreement while
ensuring that changes in rates are considered in a separate proceeding, per the
Commission's directives in Order Nos. 35482 and 35777.
19. More specifically, the Second Revised Exhibit 3.1 to the Second
Amendment updates the timing of pricing component updates to following submission of
each IRP filing and amends definitions under Block 2 by modifying the definitions of
"Excess Generation Price" and "Supplemental Energy Price" and adding "Mid-Columbia
Forecast" as a defined term.
20. A copy of the Second Amendment to the Brisbie Special Contract is
attached to this Application as Attachment 1 and as set forth therein is subject to the
Commission's approval.
Third Amendment to the Micron Special Contract
21. Similar to the modifications incorporated in the Second Amendment to the
Brisbie Special Contract, the Third Amendment to the Micron Special Contract dated April
11, 2024, provides for replacing the pricing exhibit to the Special Contract, Revised
Exhibit 1, in its entirety with the Second Revised Exhibit 1, to incorporate language for
clarity and to provide for necessary flexibility in administering the Agreement while
ensuring that changes in rates are considered in a separate proceeding.
22. More specifically, the Second Revised Exhibit 1 to the Third Amendment:
updates the timing of pricing component updates to following submission of each IRP
filing, modifies the definition of "Excess Generation Price", and adds "Mid-Columbia
Forecast" as a defined term.
APPLICATION - 8

23. A copy of the Third Amendment to the Micron Special Contract is attached
to this Application as Attachment 2 and as set forth therein is subject to the Commission's
approval.
III. UPDATES TO PRICING ELEMENTS
24. In this proceeding, the Company requests the Commission approve the
following 2023 IRP-informed prices as referenced in the Brisbie and Micron ESAs and the
City of Boise's CEYW Agreement: (1) the "Supplemental Energy Price" applicable to
Brisbie's Block 2 load service, and (2) the "Mid-Columbia Forecast" relied upon to
determine the "Excess Generation Price" applicable to Brisbie, Micron, and the City of
Boise's Excess Generation.
25. Supplemental Energy Price. The Company is seeking Commission
approval to rely on the Avoided Cost Averages published in Idaho Power's most recently
filed IRP as a basis for the Supplemental Energy Price that will be applied to Block 2 of
Brisbie's load service. The proposed prices are contained in Attachment 3 and reflect
what was filed on page 18 of "Appendix C: Technical Report" to the 2023 IRP.
26. Mid-Columbia Forecast. The Company is also seeking approval of the
hourly Mid-Columbia Forecast from the 2023 IRP for use to value Brisbie, Micron, and
the City of Boise's Excess Generation. In Order Nos. 35777 and 35482, the Commission
found the Excess Generation for Micron and Brisbie, respectively, should be valued at
the lower of (1) 85 percent of the hourly Mid-Columbia price forecast used in Idaho
Power's most recently acknowledged IRP (with a non-firm adjustment applied to each
hour's price) or (2) the actual heavy load or light load hour Mid-Columbia market price.
As noted above, the proposed contract language references relying on the most recently
APPLICATION - 9

filed IRP in lieu of the most recently acknowledged IRP, and accordingly, the Company
respectfully requests the Commission approve the Mid-Columbia Forecast from the 2023
IRP, as contained in Attachment 4, effective the first calendar day of the month following
a Commission order.
27. In preparation of the 2023 IRP, the Company changed from a 50th percentile
("P50") to a 70th percentile ("P70") energy and peak load forecast, in part due to feedback
received in the 2021 IRP cycle. More recently, Staff raised concerns in its comments filed
in Case No. IPC-E-23-23 on February 15, 2024, regarding the reliance of a P70 in the
2023 IRP, indicating the higher load forecast percentile may inflate expected energy costs
for customer rates and avoided cost rates where those rates rely on information from the
IRP.
28. As more fully articulated in its Reply Comments in Case No. IPC-E-23-23,
Idaho Power believes utilizing the P70 load forecast is a valid way to account for extreme
weather events and other reliability risks that may occur on Idaho Power's system.
Similarly, relying on those price streams for customer rates (in the case of Brisbie's
Supplemental Energy Price) or as a floor to compensate non-firm excess generation (in
the case of Micron and Brisbie's Mid-Columbia Forecast) is reasonable.
29. In recognition that a single percentile of load cannot be expected every year,
and rather should be expected to vary from year to year, the Company calculated the
Loss of Load Expectation ("LOLE") over a range of peak load forecast percentiles utilizing
the capacity positions to meet a 0.1 event-days per year LOLE threshold using both the
P50 and P70 for all six test years used in the 2023 IRP analysis. The result of that analysis
demonstrates that utilizing the P50 load forecast as a base produces an average LOLE
APPLICATION - 10

across all percentiles of 0.1650 event-days per year; however, utilizing the P70 load
forecast as a base produces an average LOLE across all percentiles of 0.0965 event-
days per year, which is close to but under Idaho Power's LOLE threshold of 0.1 event-
days per year and, therefore, validates use of the P70 peak load forecast.
30. The Company further completed an analysis to assess the comparative
impact of relying on the P70 forecast versus the P50 when considering customer rates
(Brisbie's Block 2 Supplemental Energy Price) and found the impact to be de minimis,
with the P70 forecast resulting in an average price increase of approximately 1 percent
over all hours of every year across the 20-year planning period relative to the P50 load
forecast. To assist in Staff and Commission review of the reasonableness of relying on
the P70 forecast, Attachment 5 to the Application contains the Avoided Cost Averages
table updated to reflect a P50 forecast, and Attachment 6 quantifies the delta in both
dollars and percent between the P70 and P50 avoided cost streams.
31. The Company also proposes to use the Mid-Columbia Forecast from the
filed 2023 IRP without modification for use in valuing Excess Generation. The Company
acknowledges the same trend will exist where the Mid-Columbia Forecast would be
slightly higher under the filed P70 assumption than it would be under a P50 assumption;
however, this is accounted for by the definition of Excess Generation Price as "the lower
of(1) 85 percent of the hourly Mid-Columbia Forecast with a non-firm adjustment applied
to each hour's price, or (2) the actual heavy or light load hour (as applicable) Mid-
Columbia market price for each hour of Excess Generation delivered." To the extent a
forecasted price under the P70 set of assumptions is slightly higher than the same hourly
forecast price under a P50 assumption, none of the three CEYW-Construction customers
APPLICATION - 11

(Micron, Brisbie, nor the City of Boise) will ever be compensated more than the actual
heavy load or light load hour, which negates the need to rely on a different Mid-Columbia
Forecast than was included in the filed 2023 IRP.
32. If the City of Boise CEYW Agreement is approved and effective on
September 1, 2024, and absent an order in the instant case approving the Mid-Columbia
Forecast from the 2023 IRP, the Company proposes to compensate the City of Boise for
Excess Generation according to what is proposed in this docket. The Mid-Columbia
Forecast from the 2023 IRP is the most recently filed and accurately represents the
intended Excess Generation Price. If there was a difference in what is ultimately approved
in this case, the Company would propose to true-up after an order is issued.
33. Consistent with the special contract amendments, the Company has
updated the respective tariff schedules for Brisbie and Micron, Schedules 33 and 26, to
reference the amended agreements included as Attachment 7. The Company has also
updated the tariff schedule for the CEYW Program, Schedule 62, to reference the
effective date of pricing elements that rely on the most recently filed IRP.
IV. FUTURE UPDATES TO CLEAN ENERGY YOUR WAY RENEWABLE
AGREEMENT PRICING ELEMENTS
34. The Company proposes the Commission direct it to file future updates for
CEYW-Construction renewable agreements that rely on the IRP for pricing within 30 days
of submission of a given IRP. This will provide Staff, the Commission, and other interested
stakeholders an opportunity for review to assess the reasonableness of the relevant
pricing component. The Company believes this is consistent with Staff's expectation, as
it most recently noted on page 20 of its 2023 IRP Comments (issued February 15, 2024,
APPLICATION - 12

in Case No. IPC-E-23-23): "Staff also recommends that for tariffs that are affected by
avoided cost calculations...separate dockets should be filed, and Staff will analyze the
Company's cost bases in those dockets."
35. To assist with administrative efficiency and transparency, the Company
further proposes that a single case be filed following each IRP to update pricing terms for
all CEYW-Construction contracts and that Schedule 62 be updated to include the effective
date and Commission order number authorizing any IRP-informed pricing elements.
V. MODIFIED PROCEDURE
36. Idaho Power believes that a technical hearing is not necessary to consider
the issues presented herein and respectfully requests that this Application be processed
under Modified Procedure (i.e., by written submissions rather than by hearing). RP 201,
et seq. If, however, the Commission determines that a technical hearing is required, the
Company stands ready to prepare and present its testimony in such hearing.
