IPC-E-25-31 APPROVAL OR REJECTION OF AN ) ENERGY SALES AGREEMENT WITH ) APPLICATION FOSSIL GULCH WIND PARK, LLC FOR ) THE SALE AND PURCHASE OF ELECTRIC ) ENERGY FROM THE FOSSIL GULCH ) WIND PARK. ) Idaho Power Company ("Idaho Power" or "Company"), in accordance with Idaho Public Utilities Commission ("Commission") Rule of Procedure' 52 and the applicable provisions of the Public Utility Regulatory Policies Act of 1978 ("PURPA"), hereby respectfully applies to the Commission for an order accepting or rejecting the Energy Sales Agreement ("ESA" or "Agreement") between Idaho Power and Fossil Gulch Wind Park, LLC ("Seller") (jointly, "Parties") under which Seller would sell and Idaho Power Hereinafter cited as RP. APPLICATION - 1 would purchase electric generation from the Fossil Gulch Wind Park ("Project" or "Facility") located in Twin Falls County, Idaho, which is a PURPA Qualifying Facility ("QF"). In support of this Application, Idaho Power represents as follows: I. BACKGROUND 1. The Project is a wind project with seven (7) 1.5 MW 77 SLE General Electric wind turbines with a 10.5 megawatt ("MW") nameplate capacity currently delivering energy to Idaho Power under an ESA dated September 9, 2004 ("2004 Agreement"). The ESA was approved by the Commission in Case No. IPC-E-04-19, Order No. 29630, issued on November 12, 2004. 2. The Agreement was amended on August 14, 2014 ("First Amendment"), to update the Mid-Columbia Market Energy Cost definition, which was approved by Commission Order No. 33184. 3. The 2004 Agreement expires on September 30, 2025. See Order No. 29630. In anticipation of the current ESA expiring, Idaho Power and Seller have been in communication since 2024, regarding the process and timing for entering into a replacement contract and Idaho Power has made multiple attempts over the intervening months to move the process forward in order to provide sufficient time for the regulatory review and approval process prior to the expiration of the existing contract. Unfortunately, despite the Company's efforts to support the Project in timely pursuing a replacement ESA as more fully described below, Seller did not accept indicative pricing, provide the final required information, and indicate intent to execute the replacement ESA until September 25, 2025. APPLICATION - 2 4. Idaho Power and Seller have been communicating regarding a replacement ESA since at least February 2024. Seller submitted a Completed Application under Schedule 73, the Qualifying Facility Energy Sales Agreement Application, as of April 3, 2024. Idaho Power provided indicative pricing to Seller on April 30, 2024. Having received no response from Seller and having received Commission approval of updated inputs to the pricing methodology, Idaho Power revoked this pricing on June 26, 2024. After Seller requested to remain in the pricing queue, Idaho Power provided updated indicative pricing on August 6, 2024. After Seller again provided no affirmative response to this indicative pricing, Idaho Power again provided refreshed indicative avoided cost pricing in February 2025. Seller indicated that it was interested in a replacement ESA, but was concerned about the then-current integration charges, in light of the proposed changes to those charges in Case No. IPC-E-25-07. In June 2025, Idaho Power provided Seller with draft indicative pricing indicating what the integration charges would be if the proposed charges in IPC-E-25-07 were approved by the Commission, and Seller requested a draft ESA without explicitly accepting the draft indicative pricing. On July 1, 2025, the Commission issued Order No. 36661 in Case No. IPC-E-25-07, approving the updated integration costs subject to a compliance filing, and on the same day, Idaho Power confirmed with the Seller that the updated integration costs would apply. On July 3, 2025, Idaho Power provided a draft ESA to the Seller, and on July 8, 2025, Idaho Power confirmed there would be no further changes to the draft ESA from its perspective. 5. Throughout this time, the upstream ownership of Seller was in flux, and the prior owner did not want to enter into a replacement ESA but rather allow the new owner to make the final decision. Idaho Power communicated with the prior owner and the new APPLICATION - 3 owner of Seller on numerous occasions throughout this time, including through August and September 2025, reiterating the urgency of the execution of a replacement ESA if Seller planned to do so. The new owner's acquisition of Seller occurred on September 17, 2025. Idaho Power again communicated with Seller's new owner on multiple occasions, with no response until September 25, 2025, at which point Seller indicated it intended to execute the replacement ESA and provided the outstanding relevant information. 6. On September 26, 2025, Idaho Power and the Seller entered into the ESA submitted herewith as Attachment 1, which is a new contract with the same QF for a new term with updated terms and conditions. The Parties intend the proposed ESA to replace the 2004 Agreement, as amended, in light of its expiration. As this Facility exceeds the current eligibility threshold for published avoided cost rates, the ESA contains prices based on the Commission-approved incremental cost integrated resource plan avoided cost methodology and has a two-year term in accordance with Order Nos. 33357 and 33419 issued in Case No. IPC-E-15-01. Additionally, the ESA contains wind integration charges as directed by the Commission in Order Nos. 30488, 36661, and 36679, as well as other provisions consistent with PURPA, FERC regulations, and the Commission's orders directing the implementation of PURPA for the State of Idaho, including but not limited to Commission Order Nos. 32697, 32737, and 32802 from Case No. GNR-E-11- 03. 7. Finally, as discussed further below, the Company recognizes that there is not time for the Commission to review and consider the ESA for approval prior to the expiration of the 2004 Agreement on September 30, 2025. As a result, the ESA will not APPLICATION -4 become effective when the 2004 Agreement expires. To allow Seller to continue to sell the generation from the Project to Idaho Power until the Commission issues an order on the ESA, the Parties entered into an interim agreement ("Interim Agreement") under which Idaho Power will accept delivery of the Project's generation from the expiration date of the 2004 Agreement until the time the Commission has either approved or rejected the ESA. Idaho Power will pay the Surplus Energy Price as defined in Article 7.3 of the ESA for this generation, subject to any true-up, adjustment, or rejection of the pricing, terms and provisions, or the contract or the Interim Agreement itself, by the Commission. II. RELEVANT LAW 8. Pursuant to PURPA and regulations of the Federal Energy Regulatory Commission ("FERC") implementing it, electric utilities are required to purchase power produced by designated QFs. Under this must purchase provision, the rate a utility must buy the power produced by the QF is generally referred to as the avoided cost rate, which is intended to reflect the incremental cost of power to the purchasing utility, which it would either generate itself or purchase from another source but for the purchase of power from the QF. See 18 CFR §292.101(b)(6). 9. While FERC is tasked with developing broad federal regulations to guide PURPA's implementation, individual state commissions are tasked with implementing PURPA at the state level. "PURPA requires that utilities buy the power output from QF's under a federal rate mechanism (i.e., avoided costs) that is determined and implemented by state utility commissions." Order No. 32697 at 7. 10. Pursuant to its authority under PURPA, this Commission has established and adopted numerous contract terms and conditions for energy sales agreements APPLICATION - 5 entered into between regulated utilities and QFs under PURPA and developed parameters for published and negotiated avoided cost rate calculations. 11. The Commission's seminal decisions on PURPA implementation, starting with Order No. 32697, established, in pertinent part, project eligibility caps for access to published avoided cost rates: a 10 average megawatts ("aMW") eligibility cap for resources other than wind and solar; and a 100 kW cap for wind and solar resources. See Order No. 32697 at 13-14. Order No. 32697 also confirmed use of the incremental cost, integrated resource plan methodology for determining negotiated avoided cost rates for a project above the published rate eligibility cap. See id. at 20-21. 12. The Commission also held that both energy and capacity should be considered in determining avoided costs, though payments for capacity should only begin at such time that the utility becomes capacity deficient. See Order No. 32697. If an existing QF seeks a new contract with the utility to replace an expiring contract, the capacity deficit date is still determined as of the date the original contract was executed, and the QF will be entitled to immediate payment for capacity under the replacement contract if it was being paid for capacity at the end of the prior agreement. See also Order No. 32871. 13. Relative to QF replacement contracts, the Commission subsequently recognized that conditions existing at the time a legally enforceable obligation was established in the prior contract could prevent a QF from ever receiving capacity payments, which would be inconsistent with the Commission's prior orders addressing QF eligibility for capacity payments. See, e.g., Order No. 34200 at 4-5. As a result, the Commission has focused on whether the utility has been relying on the QF's power APPLICATION - 6 production to meet its capacity needs in determining whether a QF qualifies for immediate capacity payments in a replacement contract. 14. The Commission has authorized Idaho Power to enter contracts with wind QFs utilizing wind integration charges, as updated through Commission directed studies. See, e.g., Order Nos. 30488, 36048, 36661, and 36679. 15. The Commission's holding in Order No. 33357 and 33419 issued in Case No. IPC-E-15-01 provides IRP-based PURPA contracts should have a term of two years. The Commission found that two-year terms align with the two-year planning cycle for the Integrated Resource Planning process and that a two-year cycle better matches the utilities' hedging and risk management practices. Order No. 33357 at 25. III. THE PROPOSED ENERGY SALES AGREEMENT 16. The Project is currently delivering energy to Idaho Power in accordance with the 2004 Agreement, which expires on September 30, 2025. Idaho Power and the Seller entered into a replacement ESA on September 26, 2025, in compliance with Commission Order No. 32697 and its progeny, which is intended to replace the 2004 Agreement and pursuant to which the Seller would continue to sell, and the Company would continue to purchase electric energy generated by the Project. A copy of the ESA is attached to this Application as Attachment 1. 17. In conformity with applicable Commission orders, the proposed ESA is for a 2-year term and contains negotiated avoided cost rates based upon the incremental cost, integrated resource plan pricing methodology as well as the wind integration charges directed by the Commission in Order Nos. 30488, 36661, and 36679. Monthly APPLICATION - 7 purchase prices are comprised of the non-levelized, Base Energy Heavy Load and Light Load components and integration charges as outlined in Appendix G of the ESA. 18. The proposed ESA contains contract provisions consistent with PURPA, FERC regulations, and the Commission's prior orders. It should be noted, however, that because the Project exceeds the capacity size threshold for published rates, certain terms and conditions vary from previously approved agreements for projects eligible for published avoided cost rates in conformity the Commission's orders and to properly implement the negotiated rates and integration charges. The following discussion highlights those distinct terms and also demonstrates the proposed ESA's compliance with certain provisions that have been the focus of Commission Staff in reviewing similar approval requests: (1) Estimated Net Energy Amounts; (2) eligibility for capacity payments; (3) verification of avoided cost rates; and (4) conformance of Article XXIII, Modification, with recent Commission orders. Mechanical Availability Guaranty ("MAG") 19. Consistent with other wind ESAs, this ESA contains provisions for a MAG, wind forecasting fees, wind integration charge, and a pricing adjustment under the MAG provision. See Order No. 30488. The Company has collected MAG damages in the past from projects with similar MAG provisions. Eligibility for Capacity Payments 20. In Case No. GNR-E-11-03, the Commission held if a QF project is being paid for capacity at the end of a contract term and enters into a replacement contract, it will be entitled to immediate payment of capacity. See Order No. 32697 at 21-22; Order No. 32737 at 5; and Order No. 32871. Subsequently, the Commission recognized that APPLICATION - 8 there may be circumstances under which a QF should still qualify for immediate capacity payments with a replacement ESA despite not receiving a separate capacity payment under the existing/expiring contract. Under broad PURPA and Commission guidelines, the primary question for determining capacity payment eligibility is whether or not the operation of the QF permits the Company to avoid or deter adding future additional capacity. See, e.g., Order No. 34200 at 4-5 and Order No. 34295 at 4-5. 21. Because the utility has been relying on the QF's power production and no significant changes are contemplated in the replacement contract, the replacement ESA contains payment for capacity for the entire term of the replacement contract in line with prior Commission orders. Verification of Avoided Cost Rates 22. Rates in the ESA were determined using the Incremental Cost Integrated Resource Plan ("ICIRP") methodology applicable to wind projects that exceed 100 kW, in conformity with applicable Commission orders, and consist of three components: (1) the avoided cost of energy, (2) the avoided cost of capacity, and (3) the wind integration charge. The non-Ievelized, heavy and light load avoided cost rates are set forth in Appendix G of the ESA. The ESA also contains a wind integration charge as set forth in Tariff Schedule 87. The wind integration charge is set forth in Appendix G of the ESA as a monthly amount for each year of the contract term. See Order Nos. 36661 and 36679. Article XXlll (Modifications) 23. In reviewing other PURPA energy sales agreements recently, the Commission has identified a heretofore standard ESA provision, Article XXIII Modification, that it determined required revisions to address scenarios involving Facility APPLICATION - 9 modifications to ensure, inter alia: the modified Facility operates under a correct and accurate contract that describes the characteristics and parameters of the modified Facility and the rate paid to the Facility and recovered from ratepayers, starting from the first operation date after the Facility is modified, reflect the proper and authorized rate of the modified Facility. See, e.g., Order Nos. 35705 and 35767. 24. The proposed ESA between Idaho Power and Seller incorporates the provisions and language recently approved by the Commission and in conformity with Order No. 35705. Other Pertinent Provisions 25. The Project is already interconnected and selling energy to Idaho Power and the ESA specifies a Scheduled First Energy Date and Scheduled Operation Date for this Project of October 1, 2025. See Appendix B. Articles IV and V of this ESA recognize that information provided under the previous agreement may still be applicable to this replacement ESA. As specified in the ESA, Idaho Power shall review the previously provided information and will accept the information as previously submitted, request updates to that information, and/or require new information to satisfy compliance with the various requirements, including Commission approval, for the Seller to be granted a First Energy Date and Operation Date for this replacement ESA. In addition, Idaho Power will monitor the ongoing requirements through the full term of this ESA. 26. The ESA provides that all applicable interconnection charges and monthly operational or maintenance charges under Schedule 72 will be assessed to Seller. Seller currently has a valid and active Schedule 72 Generator Interconnection Agreement, or "GIA," with Idaho Power. PURPA QF generation must be a designated network resource APPLICATION - 10 ("DNR") to serve Idaho Power's retail load on its system. In order for the Facility to maintain its DNR status, there must be a power purchase agreement associated with its transmission service request in order to maintain compliance with Idaho Power's non- discriminatory administration of its Open Access Transmission Tariff ("OATT") and maintain compliance with FERC requirements. 27. Article XXI of the ESA provides that it will only become finally effective upon the Commission's approval of all of the ESA's terms and conditions and finding that all payments Idaho Power makes to the Seller for purchases of energy will be allowed as prudently incurred expenses for ratemaking purposes. IV. PROCEDURE 28. 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. 29. The Company acknowledges that the Seller's delay in completing the Schedule 73 contracting process has resulted in insufficient time for the Commission to review the replacement ESA and for the regulatory approval process to be completed prior to the expiration of the existing agreement on September 30, 2025. Because the replacement ESA will not be finally effective until it is approved by the Commission pursuant to Article XXI of the ESA, there will be a lapse between the expiration of the 2004 Agreement and the approval of the replacement ESA. In this regard the Company notes that, under similar circumstances, the Commission has approved both energy and APPLICATION - 11 capacity payments during a lapsed contract period using the Surplus Energy Price set forth in the new contract. 30. The Company understands that a procedural schedule that would result in a final Commission determination by September 30, 2025, is not feasible, and therefore contemplated the need for an interim arrangement; absent alternative direction from the Commission, the Company proposes to pay the Seller for any generation delivered from the Facility during the lapsed contract period (September 30, 2025, until the service date of the final order issued by the Commission) at the Surplus Energy Price as defined in Section 7.3 of the Replacement ESA. Consistent with the approach taken in Case No. IPC-E-21-08 (as approved by the Commission in Order No. 35067) and Case No. IPC-E- 24-09 (as approved by the Commission in Order No. 36223), the Parties have agreed that the Company will pay for any generation delivered from the Facility during the lapsed contract period (September 30, 2025, until the service date of the final order issued by the Commission) at the Surplus Energy Price as defined in Section 7.3 of the Replacement ESA subject to any true-up, adjustment, or rejection of terms and provisions, or the contract itself, by the Commission. See September 27, 2025, Letter Agreement provided as Attachment 2. APPLICATION - 12 V. COMMUNICATIONS AND SERVICE OF PLEADINGS 31. Communications and service of pleadings, exhibits, orders, and other documents relating to this proceeding should be sent to the following: Donovan E. Walker Energy Contracts Lisa C.

Facility Nameplate Capacity: 10.5 MW Individual Generator Power Factor: Leading 0.9, Lagging 0.9 Qualifying Facility Category (Small Power Production or Cogeneration): Small Power Production Primary Energy Source (Hydro, Wind, Solar, Biomass, Waste, Geothermal): Wind Fueled or Non-Fueled Rate (Generator primarily fueled with fossil or non-fossil fuel): Non-Fueled Any modifications to the Facility, including but not limited to the generator or turbine, that 1) increases or decreases the Facility Nameplate Capacity, or 2) changes the Qualifying Facility Category, or 3) changes the Primary Energy Source or 4) changes to the generator fuel and subsequently the Fueled Rate or Non-Fueled Rate, will require a review of the Agreement terms, conditions and pricing. Idaho Power, at its sole determination, may adjust the pricing or terminate the Agreement. If the Agreement is terminated because of said modifications, the Seller will be responsible for any Termination Damages. Confidential Page 57 Docusign Envelope ID:7DA4D F9B-0439-46E 1-8934-D2 DOB 1 C8F9A6 Idaho Power Company Fossil Gulch ESA B-2 Location of Facility Near: 3.5 miles WNW of Hagerman, ID County: Twin Falls GPS Coordinates: 42.851111, -114.949444 Description of Interconnection Location: 500 East 5900 North Hagerman, ID 83332 Nearest Idaho Power Substation: Fossil Gulch (FSGL) B-3 Scheduled First Energy and Operation Date This Facility is interconnected and already delivers energy to Idaho Power pursuant to a Firm Energy Sales Agreement that expires on September 30, 2025. The First Energy Date and the Operation Date for this Agreement will be at hour beginning 00:01 on October 1, 2025, provided that the Commission approves the replacement Agreement, and the Seller completes all of the Article 4 and Article 5 requirements prior to October 1, 2025. B-4 Maximum Capacity Amount: This value will be 10.5 MW which is consistent with the value provided by the Seller to Idaho Power in the GIA. This value is the maximum energy (MW) that potentially could be delivered by the Seller's Facility to the Idaho Power electrical system at any moment in time. B-5 Point of Delivery "Point of Delivery" means, unless otherwise agreed by both Parties, the point of where the Seller's Facility energy is delivered to the Idaho Power electrical system. The GIA will determine the specific Point of Delivery for this Facility. The Point of Delivery identified by the GIA will become an integral part of this Agreement. Confidential Page 58 Docusign Envelope ID:7DA4D F9B-0439-46E 1-8934-D2 DOB 1 C8F9A6 Idaho Power Company Fossil Gulch ESA B-6 Losses If the Idaho Power metering equipment is capable of measuring the energy deliveries by the Seller to the Idaho Power electrical system at the Point of Delivery, no Losses will be calculated for this Facility. If the Idaho Power metering equipment is unable to measure the energy deliveries directly at the Point of Delivery, the Losses will be calculated. This loss calculation is currently set at zero percent (0%) of the kWh electricity production recorded on the Facility generation metering equipment. If at any time during the term of this Agreement, Idaho Power determines that the loss calculation needs to be revised due to a change in the electrical equipment or some other factor, then Idaho Power may adjust the calculation and retroactively adjust the previous month's kWh loss calculations. B-7 Designated Network Resource (DNR) This Facility is an Idaho Power DNR pursuant to an existing energy sales agreement. The DNR status will continue if this Agreement is 1) executed and approved by the Commission, and 2) a GIA has been executed by both parties and 3) the Seller is in compliance with all requirements of that GIA. Idaho Power cannot accept or pay for generation from this Facility if the Facility has not achieved the status of being an Idaho Power DNR. Federal Energy Regulatory Commission ("FERC") rules require Idaho Power to prepare and submit the application to achieve DNR status for this Facility. Because much of the information Idaho Power needs to prepare the DNR application is specific to the Seller's Facility, Idaho Power's ability to file the DNR application in a timely manner is contingent upon timely receipt of the required information from the Seller. Prior to Idaho Power beginning the process to enable Idaho Power to submit a request for DNR status for this Facility, the Seller shall have 1) filed a Generation Confidential Page 59 Docusign Envelope ID:7DA4D F9B-0439-46E 1-8934-D2 DOB 1 C8F9A6 Idaho Power Company Fossil Gulch ESA Interconnection application, 2) submitted all information required by Idaho Power to complete the application, and 3) either executed this Agreement or, at a minimum, provided Idaho Power with confirmation of the Seller's intent to complete this Agreement in a timely manner. Seller's failure to provide complete and accurate information in a timely manner can significantly impact Idaho Power's ability and cost to attain the DNR designation for the Seller's Facility and the Seller shall bear the costs of any of these delays that are a result of any action or inaction by the Seller.

Seller and Idaho Power will share the cost of Wind Energy Production Forecasting. The Facility's share of Wind Energy Production Forecasting is determined as specified below. Seller's share will not be greater than one-tenth percent (0.1%) of the total energy payments made to Seller by Idaho Power during the previous Contract Year. 1) For every month of this Agreement beginning with the first full month after the First Energy Date as specified in Appendix B of this Agreement, the Wind Energy Production Forecasting Monthly Cost Allocation ("MCA") will be due and payable by the Seller. Any Wind Energy Production Forecasting MCAs that are not reimbursed to Idaho Power shall be deducted from energy payments to the Seller. 2) During the first Contract Year, as the value of the one-tenth percent (0.1%) cap of the Facilities total energy payments will not be known until the first Contract Year is complete, Idaho Power will deduct the Facility's calculated share of the Wind Energy Production Forecasting costs specified in item d each month during the first Contract Year and subsequently refund any overpayment (payments that exceed the cap) in equal monthly amounts over the ensuing Contract Year. Confidential Page 68 Docusign Envelope ID:7DA4D F9B-0439-46E 1-8934-D2 DOB 1 C8F9A6 Idaho Power Company Fossil Gulch ESA 3) The cost allocation formula described below will be reviewed and revised if necessary on the last day of any month in which the cumulative MW nameplate of wind projects having Commission approved agreements to deliver energy to Idaho Power has been revised by an action of the Commission. 4) The monthly cost allocation will be based upon the following formula: Where: Total MW ("TMW") is equal to the total nameplate rating of all QF wind projects that are under contract to provide energy to Idaho Power Company. Facility MW ("FMW") is equal to the nameplate rating of this Facility as specified in Appendix B. Annual Wind Energy Production Forecasting Cost ("AFCost") is equal to the total annual cost Idaho Power incurs to provide Wind Energy Production Forecasting. Idaho Power will estimate the AFCost for the current year based upon the previous year's cost and expected costs for the current year. At year-end, Idaho Power will compare the actual costs to the estimated costs and any differences between the estimated AFCost and the actual AFCost will be included in the next year's AFCost. Annual Cost Allocation ("ACA") =AFCost X (FMW/TMW) And Monthly Cost Allocation ("MCA") =ACA/ 12 5) The Wind Energy Production Forecasting MCA is due and payable to Idaho Power.

The ESA replaces an expiring contract that the Seller's Fossil Gulch Wind Project("Project") has delivered generation under for twenty (20) years. In accordance with Article 2 1.1 of the ESA, "This Agreement shall only become finally effective upon the Idaho Public Utilities Commission's ("Commission") approval of all terms and provisions hereof without change or condition and declaration that all payments to be made to Seller hereunder shall be allowed as prudently incurred expenses for ratemaking purposes." Due to the timing of when the ESA was fully executed by both parties on September 26, 2025, and will subsequently be submitted to the Commission shortly for its approval or rejection of the ESA, it is not possible for the Commission to complete its review of the ESA before the existing agreement expires and the ESA's First Energy Date and Commercial Operation Date occur on October 1, 2025. However, due to operational circumstances, and considering that the existing facility has delivered generation to Idaho Power for 20 years, the Seller desires to continue providing generation during the interim period from the existing agreement's expiration, until such time as the Commission has issued an order approving or rejecting the ESA("Interim Period"). Therefore, pursuant to this letter agreement, and provided that all ESA First Energy Date and Commercial Operation Date requirements will be satisfied, Idaho Power will accept delivery of generation from the Seller's facility from the existing agreement's expiration date, September 30, 2025, until the Commission has either approved or rejected the ESA. For any generation delivered during the Interim Period, Idaho Power shall pay the Surplus Energy Price as defined in Article 7.3 of the ESA subject to any true-up, adjustment, or rejection of the pricing, terms and provisions, or the contract or this letter agreement itself, by the Commission. Idaho Power reserves the right to terminate this letter agreement at any time. Should this letter agreement be terminated by the Company, Seller shall immediately stop making any deliveries of generation to Idaho Power.
