IPC-E-24-18 APPROVAL OF A CLEAN ENERGY YOUR ) WAY CONSTRUCTION AGREEMENT WITH ) APPLICATION THE CITY OF BOISE AND THE FIRST ) AMENDMENT THERETO. ) Idaho Power Company ("Idaho Power" or "Company"), in accordance with RP 52 and Idaho Code §§ 61-502 and 61-503, hereby requests that the Idaho Public Utilities Commission ("Commission") issue an order approving the Clean Energy Your Way ("CEYW") Renewable Construction Agreement with the City of Boise City ("City of Boise" or "City"), as well as the First Amendment thereto, which authorizes the City to purchase up to 10 megawatts ("MW") from the existing and active Power Purchase Agreement ("PPA") between Idaho Power and Black Mesa Energy, LLC ("Black Mesa" or"Renewable Resource"). The Black Mesa PPA was previously approved by the Commission in Order No. 35482 on August 1, 2022.' The Renewable Construction Agreement is included 'Case No. IPC-E-22-06, In the Matter of Idaho Power Company's Application for Approval of a Replacement Special Contract with Micron Technology, Inc. and a Power Purchase Agreement with Black Mesa Energy, LLC. APPLICATION - 1 herewith as Attachment 1. The First Amendment is included herewith as Attachment 2. In this Application, the Company seeks the Commission's approval to commence the CEYW Renewable Construction Agreement, as amended, with the City of Boise beginning September 1, 2024, and in accordance with the pricing terms listed in Revised Exhibit 1 included with Attachment 2 of this Application. The Agreement under review in this case leverages CEYW pricing already approved by the Commission and formalizes contract provisions in Micron, Technology, Inc.'s ("Micron") Commission-authorized Special Contract to share a portion of the Black Mesa project with an interested third- party customer of Idaho Power. Idaho Power's Application is based on the following: I. BACKGROUND 1. The City of Boise has adopted a goal of 100 percent clean electricity use across city government operations by 2030. The City has engaged in discussions with Idaho Power dating back to 2019 to determine what Idaho Power programs, if any, could be accessed to support the City in achieving its clean energy objectives. The City of Boise was an active participant in the development of the CEYW program via the regulatory process and has continued to work with Idaho Power on ways to participate in the CEYW program, most recently through the execution of the Renewable Construction Agreement for which the Company seeks authorization in this Application. 2. The Renewable Construction Agreement between Idaho Power and the City is consistent with the CEYW Construction framework, as proposed by the Company in Case No. IPC-E-21-40 and approved by the Commission in Order No. 35893.2 2 In the Matter of Idaho Power Company's Application to Expand Clean Energy Offerings Through the Clean Energy Your Way Program. APPLICATION - 2 Additionally, the Renewable Construction Agreement leverages a provision in Micron's Commission-approved Special Contract that allows for another Idaho Power customer to purchase a share of generation from Black Mesa3: Micron and Idaho Power agree that 10 MW of the Project Output from the Black Mesa Renewable Resource PPA may be reserved and potentially dedicated to another customer of Idaho Power, at the election of Idaho Power. If such an election is exercised, then the "Project Output" for the Black Mesa Renewable Resource PPA [for Micron] shall be 30 MW. 3. While the Renewable Construction Agreement between the City and Idaho Power is consistent with the framework for the CEYW Construction option, it has two notable differences from the previous CEYW Construction agreements authorized by the Commission for Brisbie, LLC ("Brisbie") and Micron. First, the City of Boise agreement does not contemplate procuring a new resource. Rather, the Renewable Construction Agreement formalizes the City as a purchaser of up to 10 MW—or 25 percent of the generation—of the existing and already authorized Black Mesa PPA. 4. Second, the Renewable Construction Agreements for Brisbie and Micron exist within those large customers' broader Special Contracts. This Special Contract vehicle is not available for the City of Boise because the City is not a Special Contract customer. The City has accounts of various sizes, including three (3) Schedule 19, Large Power Service ("Schedule 19"), accounts that are eligible for the CEYW Construction Option provision contained in Schedule 62, Clean Energy Your Way Program ("Schedule 62"). The City seeks to apply the Schedule 62 CEYW Construction option to two (2) of the City's three (3) Schedule 19 accounts. As such, this Application is Idaho Power's first request to authorize a Schedule 62 CEYW Renewable Construction Agreement with a 3 Case No. IPC-E-22-06, Direct Testimony of Connie Aschenbrenner, Exhibit 1, Section 9.3, p 20-21. APPLICATION - 3 customer billed under Schedule 19. 5. Consistent with the Commission-authorized framework for the CEYW Construction option, the Company does not propose to modify any aspect of the City of Boise's existing pricing under Schedule 19. Rather, the Company proposes to authorize additional charges and credits associated with the Renewable Resource and consistent with the charges for CEYW customers on Schedule 19, as listed in Schedule 62. II. CITY OF BOISE CEYW TERMS AND PROVISIONS 6. CEYW Contract Overview. As introduced above, the Renewable Construction Arrangement between Idaho Power and the City of Boise builds upon a third-party customer off-taker provision in Micron's Special Contract. Within the Renewable Construction Arrangement under review in this case, the City is positioned as a "Buyer" of generation and environmental attributes from the Black Mesa PPA. More specifically, the Renewable Construction Agreement defines the City's purchase authority and staggered timeline in Section 1.6 under the "Buyer's Share" definition: "Buyer's Share" means up to 25%. All generation and Environmental Attributes from the Black Mesa Renewable Resource PPA will be allocated up to a 75% - 25% basis according to the ramp referenced below in this Section, 25% representing the Buyer's Share and 75% representing the share of another Idaho Power customer. The initial Buyer's Share, effective September 1, 2024, shall be up [to] [sic] 8 MW or 20%. Effective September 1, 2025, Buyer's Share shall be 9 MW or 22.5%. Effective September 1, 2026, and each year thereafter, Buyer's Share shall be 10 MW or 25%. 7. The "ramp" schedule as referenced above in the "Buyer's Share" definition was designed to align with the load growth forecast for the City's two Schedule 19 accounts to which this Renewable Construction Agreement applies: the Boise Airport and the Lander Street Water Renewable Facility ("Lander Facility"). The load forecast for APPLICATION -4 these two facilities was provided by the City of Boise, reviewed by Idaho Power, and then matched with an amount of generation from Black Mesa such that renewable generation supporting these facilities would not exceed 110 percent of these facilities' forecast annual energy use. 8. While the City of Boise has three Schedule 19 accounts, the City, in consultation with Idaho Power, selected the Boise Airport and the Lander Facility as the best options for this Renewable Construction Arrangement. As a highly visible location, the Airport is an important public facility for the City to associate with its clean electricity goal. Meanwhile, the Lander Facility is a major source of the City's electric demand. 9. As this Renewable Construction Agreement builds off an existing agreement between Idaho Power and Micron, the treatment of the Renewable Resource remains the same. That is, Black Mesa does not serve Micron directly nor will it serve the City directly. Rather, Black Mesa is connected directly to the Company's transmission system. Micron is currently paying for the full output from Black Mesa at the PPA contract rate and is credited for the established value the resource brings to Idaho Power's system. Similarly, beginning September 1, 2024 (a date that aligns with the start of Micron's fiscal year), the City of Boise will begin taking a share of Black Mesa, also at the PPA contract rate and receiving an associated share of credit for the Renewable Resource's value to Idaho Power's system. Finally, the environmental attributes associated with Black Mesa— in the form of Renewable Energy Certificates ("REC")—associated with the City's Buyer's Share of generation will be fully claimed by the City of Boise. 10. Pricing and Billing. Pricing and billing are detailed in Exhibit 1 as part of Attachment 2 to this Application. At a high level, pricing and credit treatment described APPLICATION - 5 herein aligns with the structure outlined for the CEYW Construction option in Idaho Power's Application in Case No. IPC-E-21-40 and the Commission's associated Order No. 35893. The City's two Schedule 19 accounts associated with this Renewable Construction Agreement will continue to be billed under Schedule 19, which includes payment for all standard services not associated with the Renewable Resource. When the Renewable Resource is not generating, the City will pay for energy under the two facilities' standard Schedule 19 energy charges. When the Renewable Resource is generating, the City will pay for its total share of output at the PPA contract rate. 11. In addition, the City will be billed a fixed cost charge on a per-kilowatt-hour basis for the amount of energy the City of Boise is no longer purchasing from Idaho Power; in other words, the amount of energy the City will no longer purchase from Idaho Power is the amount of generation the City will purchase associated with its share of Black Mesa. The fixed cost charge for Schedule 19 customers with a CEYW Construction agreement is detailed in Schedule 62. 12. The City will also be credited for the benefits derived from its share of the resource through a Renewable Energy Facility Credit. The methodology to derive this credit is based on the authorized methodology used in Micron's Special Contract. 13. Finally, the City of Boise will receive an Excess Generation Price for any amount of its share of generation that exceeds the energy requirements of the City's two applicable facilities in a given hour. The Excess Generation Price will be the lesser of the Commission-authorized Mid-Columbia ("Mid-C") market forecast prices stemming from Idaho Power's most recently filed Integrated Resource Plan ("IRP") or actual Mid-C heavy or light load hourly prices. This Excess Generation Price construct is consistent with the APPLICATION - 6 Commission's decisions in both the Brisbie and Micron cases, Order Nos. 35777 and 35482, respectively. 14. Contingency Fund. The Renewable Construction Agreement between the City of Boise and Idaho Power contains provisions intended to financially protect Idaho Power and its customers in the unlikely event of a default by the City of Boise. Section 8 of the Renewable Construction Agreement outlines the Contingency Fund that has been established by the City of Boise. 15. The Contingency Fund would be used to cover energy costs associated with the City of Boise's share of the PPA if the City defaulted on this contract. The Contingency Fund amount of $810,000, which is equivalent to $81,000 per MW for the City's maximum 10 MW share of Black Mesa, is sized to cover any differences between the Renewable Resource PPA contract value and the amount for which Idaho Power could sell the City's share of Black Mesa generation on the market. The methodology for establishing the Contingency Fund is consistent with the per MW of nameplate approach used to develop the credit support mechanisms for both Brisbie and Micron. 16. No-Harm Financial Analysis. In consultation with Commission Staff, Idaho Power completed an analysis to evaluate any impact on non-participants due to the proposed change in the allocation of Black Mesa from Micron to the City of Boise. The proposed arrangement, with as much as 25 percent of Black Mesa allocated to the City of Boise, was compared against the current arrangement with 100 percent of Black Mesa allocated to Micron. 17. The Company considered each pricing component under the existing Micron arrangement and the proposed City of Boise arrangement. Idaho Power began APPLICATION - 7 the impact analysis by identifying the pricing components that would not be impacted or change due to a pro-rata allocation of Black Mesa and then isolating the pricing components that could change under the proposed arrangement. 18. The Company identified three pricing components that remain unchanged under either arrangement and, therefore, have no impact on non-participants: • The Black Mesa PPA will continue to be paid and guaranteed in full under either arrangement. • The capacity credit value included in Idaho Power's Power Cost Adjustment will not change under the proposed arrangement with the City of Boise— allocation of the generation of the project does not change the overall capacity contribution of the Renewable Resource. • The fixed cost of energy would be collected in full under both arrangements— via the Embedded Energy Fixed Cost for Micron and the Schedule 19 fixed cost charge identified in Schedule 62 for the City of Boise. 19. Idaho Power identified two components of the proposed arrangement with the City of Boise that would be different: • Micron's embedded energy rate is lower than the City of Boise and, therefore, would result in a change to Idaho Power's revenue collection. • Micron will not have any excess generation associated with Black Mesa, considering the size of the resource relative to Micron's total load. The City of Boise's share of Black Mesa, however, will create excess generation at its two (2) Schedule 19 facilities in some hours. APPLICATION - 8 20. Considering only the two items that will change under the proposed City of Boise arrangement, Idaho Power evaluated the impact on non-participates using a two- step analysis, each with a "pass/fail" determination. 21. For the first step, Idaho Power analyzed whether the City of Boise's reduction in embedded energy collection would exceed the additional energy collection from Micron. In each of the ten years evaluated (beginning September 1, 2024, with the City taking an allocation of Black Mesa), the additional energy sales from Micron exceeded the reduced energy sales for the City of Boise. As a result of this outcome of additional energy sales-based revenue, there is no impact on non-participants, awarding this first-step screen a "pass" rating. 22. For the second step, Idaho Power considered the cost of excess generation, using the IRP Mid-C forecast from the Company's 2021 and 2023 IRPs.4 Using both Mid- C forecasts from the two IRPs to price excess generation, the value of the excess generation created from the City of Boise's share of Black Mesa was less than the value of additional energy sales from the first step of this impact evaluation, creating no negative financial impact on non-participants and giving this second step of the analysis a "pass" rating. 23. The Company recognizes that the outcome of this second analysis will depend on what actual market prices are in the future, with higher market prices having the potential to create a negative impact on non-participants. Mid-C actuals are unavailable for any forward-looking analysis, but to test the sensitivity of this second analysis to higher market prices, the Company also evaluated potential Mid-C prices at 4 Actual Mid-C prices are unavailable for any forecast view. APPLICATION - 9 2.25x higher than the Mid-C forecasts from the 2021 and 2023 IRPs. Under this high- market cost sensitivity over 10 years, each year of the analysis showed an overall benefit (that is, the additional energy sales revenue exceeding the cost of excess generation), thus indicating that the proposed pro-rata share to the City of Boise passes the no-harm analysis in both steps of the analysis and under a high market price sensitivity scenario. III. CITY OF BOISE PARTICIPATION IN BLACK MESA 24. On February 16, 2022, Idaho Power and Black Mesa entered into a PPA for the sale and purchase of 40 MW of renewable solar electric generation from the Black Mesa project for the period of 20 years from a commercial operation date of June 1, 2023. The Commission approved the Black Mesa PPA in Order No. 35482 on August 1, 2022. 25. The City of Boise's participation in Black Mesa (that is, purchasing a share of the generation) does not modify any aspect of the existing and active PPA. The Renewable Construction Agreement that is the subject of this Application is focused entirely on the terms of the City of Boise's CEYW Construction arrangement with Idaho Power. 26. The City of Boise's stake in purchasing a share of Black Mesa would begin on September 1, 2024, a date determined to be optimal by Micron. Micron's fiscal year begins on September 1, making this a logical and efficient transition date for the City of Boise to begin its participation in the Black Mesa CEYW Construction option. 27. As stated in Section 1.6 of the Renewable Construction Agreement between the City of Boise and Idaho Power, the City will have a staggered purchase schedule of Black Mesa generation, beginning with 8 MW of nameplate capacity (or 20 percent of generation) in the first year, 9 MW of nameplate capacity (or 22.5 percent of generation) APPLICATION - 10 in year two, and the maximum 10 MW of nameplate capacity (or 25 percent of generation) from year three until the contractual end date of the PPA. 28. First Amendment. On April 16, 2024, Idaho Power and the City executed the First Amendment to the Renewable Power Purchase Agreement Between Idaho Power Company and the City of Boise. The First Amendment made several clarifying corrections to the Renewable Construction Agreement to: (1) add "Project Output " to the list of defined terms in Section 1 — Definitions and Interpretation, which is a term that is used in the Agreement but was inadvertently not included in Section 1; (2) add a definition for "Supplemental Energy", which is erroneously noted in Section 1 of the Agreement as being defined in Exhibit 1, and correct that reference elsewhere in the Agreement; and (3) modify Exhibit 1, which sets forth the details of the all rate components and pricing under the Agreement, 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. IV. MODIFIED PROCEDURE 29. Idaho Power believes that a 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. Additionally, as previously stated, the City of Boise's participation in and purchase of a 25 percent share of the Black Mesa project aligns with the beginning of Micron's fiscal year of September 1, 2024, as well as the beginning load ramp period in section 1.6 of the City's Renewable Construction Agreement. Consequently, Idaho Power respectfully APPLICATION - 11 requests the Commission consider a procedural schedule that would allow for a final Order prior to September 1, 2024. V. COMMUNICATIONS AND SERVICE OF PLEADINGS 30. Communications and service of pleadings with reference to this Application should be sent to the following: Donovan E.

Approval of the City of Boise's CEYW Construction Agreement, as amended, is consistent with prior Commission orders related to CEYW and in the public interest. Idaho Power and the City of Boise have worked together to establish a contract that represents meaningful progress toward accomplishing the City's clean energy goals, while ensuring the related pricing appropriately assigns the costs and benefits of a share of the Renewable Resource to the City. The structure presented in this case is also consistent with the elements presented in the CEYW Construction option. All costs associated with the City's agreed-upon share of Black Mesa will be paid for by the City, which ensures other customers are not harmed by the arrangement. The City's rates associated with service under Schedule 19 will not change, and the added rates, charges, and credits associated with the City's Renewable Construction Agreement, as amended, and Schedule 62 are just, reasonable, and consistent with past CEYW orders. APPLICATION - 12 THEREFORE, Idaho Power respectfully requests that the Commission issue an Order before September 1, 2024, approving the attached CEYW Renewable Construction Agreement and the First Amendment thereto between the City of Boise and Idaho Power.

Following response from City of Boise to the Notice of Renewable Resource PPA Default, Idaho Power shall enforce its contractual rights (including, if City of Boise has provided written consent, the right to suspend performance and/or terminate) in accordance with the terms of such Renewable Resource PPA and Prudent Electrical Practice. Idaho Power shall enforce the terms of the Renewable Resource PPA and collect from the Developer any Termination Payment or damages owed as a result of such Renewable Resource PPA Default; provided, that, assuming Idaho Power has used Commercially Reasonable Efforts to enforce the terms of the Renewable Resource PPA, Idaho Power shall not be obligated to pay to City of Boise termination damages due from but not paid by the Developer. Any delay damages or cover damages received from the Developer, minus any reasonable costs incurred by Idaho Power in recovering such delay damages or cover damages (including, but not limited to, the cost of all Supplemental Energy as defined in Exhibit 1 that is provided by Idaho Power in lieu of the Metered Output and Environmental Attributes), shall be forwarded by Idaho Power to City of Boise, as, when and to the extent such delay damages or cover damages are actually received by Idaho Power. If during the pendency of a Renewable Resource PPA Default, Idaho Power does not acquire the Metered Output and Environmental Attributes of the Renewable Resource PPA due to a Renewable Resource PPA Default, Idaho Power shall provide Supplemental Energy, and City of Boise shall Page 19 of 43 DocuSign Envelope ID: 18ABCF27-B954-401F-9F1A-59F55C714BCF pay the cost of all Supplemental Energy as defined in Exhibit 1 that is provided by Idaho Power in lieu of the Metered Output. b. Upon termination of the Renewable Resource PPA as a result of a Renewable Resource PPA Default as contemplated by Section 7.2(a): (i) Idaho Power shall calculate the Termination Payment, if any, due and owing under the Renewable Resource PPA; (ii) Idaho Power shall exercise any rights Idaho Power may have against any collateral or security posted by the Developer and held by or on behalf of Idaho Power, (iii) Idaho Power may, to the extent allowed under the terms of the Renewable Resource PPA, apply the proceeds of collateral posted by the Developer against any Termination Payment owed by the Developer, and (iv) if Idaho Power is owed such Termination Payment from the Developer, Idaho Power shall forward to City of Boise any such Termination Payment and other amounts recovered minus any reasonable and documented costs incurred by Idaho Power in recovering such Termination Payment, not to exceed the Termination Payment recovered, as, when and to the extent such Termination Payment and other amounts are actually received by Idaho Power. 7.3 Payments Subject to Reclaim. In the event that any payments received from Developer and forwarded to City of Boise, including any delay damages, cover costs or Termination Payment, must subsequently be returned to Developer or any Person acting in the Developer's or its creditor's interest or is reclaimed by any Governmental Authority as a preference or upon a fraudulent transfer action, then unless such requirement to return or such reclamation is the result of an act or omission of Idaho Power, such amount shall be returned by City of Boise to Idaho Power. 7.4 No Greenhouse Gas-Specific or REC-Retiring Imports. Idaho Power will ensure that the Metered Output and Project capacity to be provided to Idaho Power is not delivered into a Claiming Jurisdiction. This includes not delivering Metered Output or Project capacity into California or into any California balancing authority area, through a sale of resource adequacy capacity to any California load serving entity, by participation in any California Independent System Operator market, participation in the Energy Page 20 of 43 DocuSign Envelope ID: 18ABCF27-B954-401F-9F1A-59F55C714BCF Imbalance Market, as an import of "specified source" energy within the meaning of California's Regulation for the Mandatory Reporting of Greenhouse Gas Emissions, or otherwise. Nothing in this Agreement prohibits Idaho Power from being a participating resource in EIM supplying energy to non-California, non-Claiming Jurisdiction participants. In the event that Idaho Power participates in any California Independent System Operator market, Idaho Power shall not claim any Environmental Attributes, or "renewable energy," "clean energy," "green energy," gy, gy, g or similar attributes from the Project or associated with the Metered Output as belonging or attributable to Idaho Power or any Project generation or facilities, and agrees it will report to City of Boise any such claims made by third parties of which Idaho Power becomes aware.

Page 21 of 43 DocuSign Envelope ID: 18ABCF27-B954-401F-9F1A-59F55C714BCF b. In the event of an Early Termination in which the City of Boise is the Defaulting Party, Idaho Power will recover its calculated damages suffered from the Early Termination ("Idaho Power Early Termination Damages") from the Contingency Fund. Idaho Power must make commercially reasonable efforts to mitigate its damages from the Early Termination, and such mitigation amounts will be offset in calculating the Idaho Power Early Termination Damages recovered from the Contingency Fund. To recover the Idaho Power Early Termination Damages from the Contingency Fund, within 180 days following an Early Termination in which the City of Boise is the Defaulting Party, Idaho Power may make an application to the Escrow Agent for disbursement of the Idaho Power Early Termination Damages from the Escrow Account Holder. The application must be served upon the City of Boise and must contain a statement showing the efforts made to mitigate damages and quantifying any required mitigation offset for the Idaho Power Early Termination Damages. The City of Boise shall have thirty (30) days within which to review the escrow disbursement request and if appropriate lodge any objection with the Escrow Account Holder to disbursement of the City of Boise Contingency Fund to Idaho Power. If no objection is made within the prescribed period, the Escrow Account Holder will disburse the requested Idaho Power Early Termination Damages to Idaho Power, and the balance of any remaining funds from the Contingency Fund will be disbursed to the City of Boise.
