PAC-E-23-01 CERTIFICATE OF CONVENIENCE AND ) NECESSITY AUTHORIZING ) APPLICATION CONSTRUCTION OF THE BOARDMAN-TO ) -HEMINGWAY 500-KV TRANSMISSION ) LINE PROJECT ) Rocky Mountain Power, a division of PacifiCorp (“Rocky Mountain Power” or the “Company”), in accordance with Idaho Code § 61-526 and Rule of Procedure (“RP”) 112 of the Idaho Public Utilities Commission (“Commission”), respectfully applies to the Commission for an order granting a certificate of public convenience and necessity (“CPCN”) for Energy Gateway Segment H, the Boardman-to-Hemingway 500-kilovolt (“kV”) transmission line (“B2H” or the “Project”). The Company will co-own B2H with Idaho Power Company (“IPC”), which recently filed its own CPCN application for the Project in Case No. IPC-E-23-01. APPLICATION OF ROCKY MOUNTAIN POWER PAGE 2 B2H is necessary to enable lower-cost and more reliable transmission service for the Company’s growing customer load and to avoid acquisition of higher-cost generation and transmission resources. The Company’s analysis of B2H demonstrates that the Project is expected to result in approximately $1.713 billion in risk-adjusted net benefits, assuming medium natural gas and carbon dioxide (“CO2”) prices. There are three principal factors that produce these significant customer benefits. First, B2H increases the ability to move resources across and between both PacifiCorp balancing authority areas (“BAA”). There currently exists only one 500-kV transmission line connecting the Company’s eastern BAA, PacifiCorp East (“PACE”) and its western BAA, PacifiCorp West (“PACW”). Increasing connections between the Company’s BAAs allows the Company to serve customers more efficiently in both areas using the most cost-effective generation available. Additionally, construction of B2H will provide regional benefits by strengthening the interconnected transmission grid in the west and enhancing resource adequacy. Second, B2H enables lower-cost and more reliable transmission service to PacifiCorp’s growing central Oregon loads. By constructing B2H and consolidating certain transmission rights with the Bonneville Power Administration (“BPA”) (as part of the B2H transaction), the Company can avoid constructing significant generation resources in southern Oregon that would otherwise be required absent B2H. Third, B2H allows for lower cost transmission service to PacifiCorp’s increasing loads in the vicinity of BPA’s planned Longhorn substation, which is the western terminus of B2H near Boardman, Oregon. B2H enables the Company to avoid significant third-party transmission expenses that would otherwise be required to serve this retail customer load. APPLICATION OF ROCKY MOUNTAIN POWER PAGE 3 The Company requests expedited review of this Application, and adoption of a procedural schedule that aligns with the schedule in Case No. IPC-E-23-01. B2H has a projected in-service date of 2026. To ensure completion of the Project by that date, construction must begin in the summer of 2023. For that reason, the Company requests that the Commission issue an order on this Application no later than June 30, 2023. In support of this Application, Rocky Mountain Power states as follows: I. NAME AND ADDRESS OF APPLICANT PacifiCorp provides retail electric service under the name Rocky Mountain Power in the states of Wyoming, Utah, and Idaho, and under the name Pacific Power in the states of Oregon, Washington, and California. Rocky Mountain Power is a public utility in the state of Idaho subject to the Commission’s jurisdiction with respect to its prices and terms of electric service to retail customers in Idaho pursuant to Idaho Code § 61-129. Rocky Mountain Power is authorized to do business in the state of Idaho providing retail electric service to approximately 88,000 customers in the state.

II. SUPPORTING TESTIMONY This Application is supported by the pre-filed written direct testimony and exhibits of the following Company witnesses:  Mr. Rick T. Link, Senior Vice President of Resource Planning, Procurement, and Optimization, demonstrates that the Project is necessary to enable lower-cost and more reliable transmission service to serve customer load. Mr. Link explains in detail the customer benefits that will result from the construction and acquisition of the Project. Mr. Link also describes the transfer of transmission rights and agreements between the Company, IPC, and BPA.  Mr. Rick A. Vail, Vice President of Transmission, provides a description of the Project and a cost estimate for its construction. Mr. Vail’s testimony describes how the Project will increase both the interconnection capacity and the transfer capability between PACE and PACW and demonstrates that the Project is APPLICATION OF ROCKY MOUNTAIN POWER PAGE 5 necessary to improve the reliability of the transmission system. Mr. Vail also explains the asset exchange that will occur between the Company and IPC in relation to the Project and the agreements between the two companies. III. OVERVIEW OF B2H B2H is an approximately 300-mile-long, 500-kV electric transmission line that will extend from a switching station proposed to be constructed near Boardman, Oregon to the existing Hemingway Substation located in Owyhee County, Idaho. Approximately 274 miles of the transmission line will be in five Oregon counties: Malheur, Baker, Union, Umatilla, and Morrow Counties. A 24-mile segment of the Project will be in Owyhee County in Idaho. Because of the length of B2H, the transmission line will also include ten communication stations along the route. These communication stations will all be constructed within the right-of- way of the transmission line. B2H will also include the installation of the B2H Midline Series Capacitor Project and development of a remedial action scheme.1 The Project has long been recognized as an integral component of the Company’s and the region’s long-term transmission plan. NorthernGrid—a planning association aiming to facilitate regional transmission planning across the Pacific Northwest and Intermountain West—has repeatedly identified B2H as a regionally significant project in its biennial regional transmission plans.2 In addition to the Company, IPC and BPA are stakeholders in B2H. The initial B2H agreement among the stakeholders was a Joint Permit Funding Agreement, executed January 12, 2012, and amended several times, to jointly support the regulatory processes associated with obtaining necessary permits and other project development work. On January 18, 2022, the parties executed a non-binding term sheet (“Term Sheet”) as the 1 Direct Testimony of Rick T. Link, Exhibit No. 1 - Term Sheet at 17 [hereinafter “Term Sheet”]. 2 See, e.g., NORTHERNGRID, Regional Transmission Plan for the 2020-2021 NorthernGrid Planning Cycle at 31 (Dec. 8, 2021) (available at https://www.northerngrid.net/private-media/documents/2020- 2021_Regional_Transmission_Plan.pdf) (last visited Jan. 24, 2023). APPLICATION OF ROCKY MOUNTAIN POWER PAGE 6 framework for future agreements, which is included as Exhibit No. 1 to the testimony of Mr. Link. Prior to execution of the Term Sheet, BPA decided to transition out of its role as a joint permit funding coparticipant and to instead take transmission service from IPC to serve its customers. BPA’s decision leaves only the Company and IPC as owners of B2H. To account for BPA’s decision to take transmission service from IPC, the Term Sheet stipulates that IPC will acquire BPA’s B2H project capacity, which will increase IPC’s B2H project ownership share to 45.45 percent.3 The Company will own the remaining 54.55 percent of B2H. Because IPC assumed the entirety of BPA’s ownership interest in B2H, BPA’s transition did not affect the Company’s ownership interest. When B2H is completed, IPC and the Company will jointly own as tenants in common the transmission line and all associated facilities and equipment.4 The Term Sheet also designates IPC as project manager for B2H. As project manager, IPC is responsible for federal, state, and local permitting efforts and construction of the Project, except that BPA will be responsible for designing, procuring, and constructing the Longhorn substation and relocating and replacing an existing BPA 69-kV line.5 The Term Sheet summarizes the various agreements the B2H stakeholders have executed to-date and those they intend to implement in the future relating to the Project.6 The agreements identified in the Term Sheet include the following: 1. The Company and IPC will execute the B2H Project Joint Construction Funding Agreement which will include definitive terms and conditions by which the parties will jointly support and contribute funds for the procurement, construction, and 3 Exhibit No. 1 - Term Sheet at 24. 4 Id. at 26. 5 Id. at 25. 6 Although these agreements all relate to B2H and the stakeholders’ expectations in constructing the Project, the Company does not seek approval of these agreements in this docket. APPLICATION OF ROCKY MOUNTAIN POWER PAGE 7 commissioning of the B2H project, allowing for energization of the Project by the earliest in-service date needed by the parties; 2. IPC and the Company will fund a portion of the proposed Longhorn substation near Boardman, Oregon;7 3. As part of the asset exchanges discussed below, IPC and the Company may expand their existing Joint Ownership and Operating Agreement, as amended, and restated August 22, 2019, to include ownership, operation and maintenance provisions associated with B2H and the revised capacity owned due to the exchanged assets;8 4. The Company and IPC will execute two additional construction agreements, the Midpoint 500/345-kV Transformer Project Construction Agreement and the Kinport – Midpoint 345-kV Series Capacitor Bank Project Construction Agreement, through which the companies will make necessary capital upgrades to exchanged assets. Additionally, the Company and IPC have agreed to exchange several transmission assets as part of the agreement governing the joint-ownership of B2H. IPC has agreed to transfer to the Company a percentage of the assets that make up the existing 500-kV and 345-kV transmission lines between the Borah, Kinport, Adelaide, Midpoint and Hemingway substations.9 The Company has agreed to transfer to IPC a percentage of the assets that make up the existing 345-kV transmission lines connecting the Populus substation to the Four Corners substation.10 Finally, the Company has agreed to transfer to IPC certain to-be-determined Goshen area transmission assets, which would allow IPC to provide transmission service to all BPA 7 Exhibit No. 1 - Term Sheet at 11 8 Id. at 14. 9 Id. at 13-14. 10 Id. at 13. APPLICATION OF ROCKY MOUNTAIN POWER PAGE 8 customers in southeast Idaho currently served by the Company.11 The agreements implementing these asset exchanges will be completed consistent with the agreed-upon Term Sheet. Although the Company and IPC intend to implement these asset exchanges in connection with B2H, these asset exchanges will not take effect until energization of B2H—which is expected to occur in 2026. For that reason, the Company does not request approval of these asset exchanges at this time. IV. LEGAL STANDARD Before constructing a transmission line, Idaho Code § 61-526 requires that a public utility obtain a “certificate that the present or future public convenience and necessity require or will require such construction[.]” When the Commission considers an application for a CPCN, the “public interest is the paramount consideration[.]”12 To determine whether the proposed resource is in the public interest, the “primary focus” of CPCN proceedings is the examination of two questions: “Does the present or future public convenience and necessity require additional resources, and is the [proposed resource] a reasonable means of meeting this need?”13 To answer the first question, the Commission often relies on the analysis in a utility’s Integrated Resource Plan (“IRP”) to demonstrate that additional resources are necessary to serve present or future customer needs.14 However, the Commission has also relied on analysis completed after the most recent acknowledged IRP when that analysis is available and further 11 Id. at 14. 12 In the Matter of Idaho Power Co. & Application for a Certificate of Public Convenience and Necessity for the Investment in Selective Catalytic Reduction Controls on Jim Bridger Units 3 and 4, Case No. I PC-E-13-16, Order No. 32929 at 10 (Dec. 2, 2013) (quoting Application of Kootenai Natural Gas Co., 78 Idaho 621, 627, 308 P.2d 593, 596 (1957)). 13 In the Matter of Idaho Power Co. Application For a Certificate of Public Convenience and Necessity For the Evander Andrews Power Plant, Case No. I PC-E-06-09, Order No. 30201 at 4 (Dec. 15, 2006). 14 See Order No. 30201 at 4; In the Matter of Idaho Power Company’s Application for a Certificate of Public Convenience and Necessity for the Ratebasing of the Bennett Mountain Power Plant, Case No. IPC-E-03-12, Order No. 29410 at 7 (Jan. 2, 2004). APPLICATION OF ROCKY MOUNTAIN POWER PAGE 9 demonstrates the need for a proposed resource.15 As to the second question, the Commission may determine that a proposed resource is reasonable if the applicant demonstrates that it is a cost-effective means of meeting the applicant’s needs.16 Here, as explained in the testimonies of Mr. Link and Mr. Vail, B2H enables lower-cost and more reliable transmission service to serve customer load and increases transmission connectivity between PACE and PACW. Mr. Link demonstrates that B2H will enable the Company to cost-effectively and reliably serve growing customer load. As explained in detail below and in Mr. Link’s testimony, these benefits primarily result from cost savings in serving load in central Oregon and near the proposed Longhorn substation. Mr. Vail’s testimony outlines the reliability benefits to the transmission system resulting from B2H. As to the reasonableness of B2H, Mr. Link’s analysis demonstrates that B2H is the most cost-effective means of serving the Company’s load. Without B2H, the Company would be required to acquire higher-cost generation resources and third-party transmission service, which together would increase customer costs by approximately $1.713 billion through 2042. The Commission has also previously provided expedited review of a CPCN application when necessary to meet construction deadlines.17 The cost savings discussed above are all based on an anticipated 2026 in-service date for B2H. To ensure that the Project can be energized in time for a 2026 in-service date, construction must begin in the summer of 2023. For that reason, the Company requests that the Commission issue an order on this Application no later than June 30, 2023. 15 Order No. 30201 at 8 (considering analysis in the applicant’s 2006 IRP, which was filed more than five months after the application for a CPCN and was not acknowledged until after the Commission granted the CPCN). 16 Order No. 29410 at 10 (finding that the proposed resource “is a reasonable response to meet the near-term needs of the Company and its customers” because it is the “most cost-effective proposal in the RFP process and was the winning project”). 17 Order No. 29410 at 5-6 (granting CPCN in just over three months because applicant’s contract with construction company “contain[ed] a construction schedule that may require modification if the Commission has not made its decision prior to” the applicant’s requested date). APPLICATION OF ROCKY MOUNTAIN POWER PAGE 10 Finally, the Commission has also granted CPCNs even when one is not strictly required by the statute.18 Here, it is unclear whether a CPCN is strictly required for B2H because IPC, not the Company, is the entity actually constructing the transmission line. The Company has made this request, however, due to the scope of B2H, the Company’s active role in overseeing the Project, and to outline the distinct and substantial benefits the Project provides to the Company’s customers. V. REQUIREMENTS OF RP 112 A. Statement and Explanation. A statement or prepared testimony and exhibits explaining why the proposed construction or expansion is or will be in the public convenience and necessity. This Application, along with the attached testimony, explain that B2H is in the public convenience and necessity and serves the public interest by providing significant net benefits to customers in a wide range of price-policy scenarios. The Project is necessary because it enables lower-cost and more reliable transmission service to serve the Company’s increasing retail customer load, particularly in central Oregon and near B2H’s western terminus at the proposed Longhorn substation. In central Oregon, the Company seeks to double its transmission rights from 340 megawatts (“MW”) to 680 MW to meet growing customer needs. B2H will enable the Company to secure this capacity increase without any additional transmission upgrades. Additionally, after acquiring B2H the Company will reduce its BPA wheeling expenses by consolidating certain point-to-point (“PTP”) reservations on BPA’s system that are used to reach central Oregon loads. In the absence of B2H, the Company will still need increased transmission into the central Oregon load area and serving that load would require dispatchable generation in southern Oregon ranging from 18 In the Matter of the Application of Rocky Mountain Power for a Certificate of Public Convenience and Necessity Authorizing Construction of the Populus-to-Terminal 345 kV Transmission Line Project, Case No. PAC-E-08-03, Order No. 30657 at 5 (Oct. 10, 2008) (granting CPCN for Populus-to-Terminal transmission line even though the Company was “not required to apply for a CPCN . . .”). APPLICATION OF ROCKY MOUNTAIN POWER PAGE 11 725 MW to 1,450 MW to prevent impacts to other existing rated paths. Without B2H, ensuring this dispatchable generation would require substantial investment in generation and in four-hour battery storage. In the Longhorn area, customer load near the proposed western terminus of B2H is also growing substantially. Because of those customers’ proximity to B2H, the Company can serve those customers via a connection to the B2H line. Without B2H, serving this growing load will require PTP transmission service from various other utilities in the region, the cost of which will be attributed to the Company’s retail customers as net power costs. To evaluate the cost-effectiveness of B2H, the Company analyzed the change in expected revenue requirement between two resource portfolios—one with B2H and one without. To ensure a robust evaluation, the Company calculated the present value revenue requirement differential (“PVRR(d)”) between the two portfolios under a range of future natural gas price and CO2 policy assumptions (“price-policy scenarios”). B2H results in significant cost savings in all scenarios compared to a non-B2H portfolio. The risk-adjusted PVRR(d) customer benefits for B2H range from $1.487 billion in a price-policy scenario assuming high natural gas and CO2 prices to $1.786 billion assuming medium natural gas and no CO2 price. In the price-policy scenario that assumed medium natural gas and medium CO2 prices, the portfolio with B2H is $1.713 billion lower cost, demonstrating the robust customer benefits resulting from B2H. Finally, the Project will improve grid reliability by providing better operational control of the backbone transmission system by interconnecting PACE and PACW on the PacifiCorp transmission system. As explained in the testimonies of Mr. Link and Mr. Vail, through B2H the Company will secure an additional 300 MW of west-to-east transmission capacity and an additional 818 MW of east-to-west transmission capacity, which will enable the Company to efficiently deploy new generating facilities and better utilize existing resources to meet anticipated resource needs. Moreover, the Project has long been recognized as an integral component of the Company’s and the region’s long-term transmission plan. The Company has partnered with IPC in a non-binding agreement to fund and own B2H to improve transmission APPLICATION OF ROCKY MOUNTAIN POWER PAGE 12 service to customers in both utilities’ service territories. BPA will also enter into wheeling agreements to deliver energy across IPC-owned equipment to BPA customers in eastern Idaho. The Company, IPC and BPA are moving forward with B2H at this time because current circumstances make it necessary and economic for their customers throughout the region. The Company requests approval of a CPCN by June 2023 so construction may begin in July 2023 to ensure an in-service date in 2026. B. Description of Construction or Expansion. A full description of the proposed construction or expansion, including the manner of construction or expansion, and if an expansion, the names of all public utilities, corporations, or persons with whom the expanded utility is likely to compete. A description of the project is included above in Section III of this Application. Additional details related to the Project are provided in the testimony of Mr. Vail. The Project will not conflict with or adversely affect the operations of any existing certificated fixed public utility providing retail electric service to the public. The Project does not constitute an extension into the certificated service territory of any existing public electric utilities. C. Map. A map of suitable scale showing the location of the construction or expansion and its relation to other public utilities in the area(s) that offer or provide similar utility service. A map of the proposed route for the Project is provided in Mr. Vail’s testimony. D. Financial Statement and Construction Timelines. A statement of the manner in which the applicant proposes to finance the construction or expansion, the time when the applicant proposes to begin the construction or expansion, and the time when the applicant proposes to complete the construction or expansion. The Company intends to finance the Project through its normal sources of capital, both internal and external, including net cash flow from operating activities, public and private debt offerings, the issuance of commercial paper, the use of unsecured revolving credit facilities, APPLICATION OF ROCKY MOUNTAIN POWER PAGE 13 capital contributions and other sources. Although the Project is a significant investment on the part of the Company, the financial impact will not impair the Company’s ability to continue to provide safe and reliable electricity service at reasonable rates. In addition, approval of the Company’s resource decision provides important regulatory support for the Company’s current credit rating. The Company anticipates the following timeline. IPC secured a site certificate from the Oregon Energy Facility Siting Council (“EFSC”) for B2H in October 2022.19 Several intervenors in the proceedings before EFSC have appealed the order issuing that site certificate. A ruling from the Oregon Supreme Court on those appeals is expected no later than June 6, 2023.20 IPC has requested issuance of CPCNs from the Commission and the Public Utility Commission of Oregon by June 30, 2023.21 Similarly, the Company in this Application requests a CPCN from the Commission by June 30, 2023. Additionally, the Company will request a non-situs CPCN from the Wyoming Public Services Commission to be issued by June 30, 2023. IPC anticipates issuing Requests for Proposals for materials and contractors during the first quarter of 2023.22 IPC anticipates selecting a construction manager in the second quarter of 2023.23 Construction is expected to begin in summer of 2023 and the Company expects B2H to be placed in-service in 2026. 19 In the Matter of the Application for Site Certificate for the Boardman to Hemingway Transmission Line, Site Certificate (Sept. 7, 2022) (available at https://www.oregon.gov/energy/facilities- safety/facilities/Facilities%20library/2022-09-27-B2H-APP-Doc32-Site-Certificate.pdf) (last visited Jan. 24, 2023) (EFSC unanimously voted to approve the Final Order and Site Certificate on September 27, and the Final Order and Site Certificate were executed on October 6, 2022). 20 See Oregon Revised Statute 469.403(6) (requiring the Oregon Supreme Court to “give priority” to appeals of orders issuing site certificates and “render a decision within six months of the filing of the petition for review”). The intervenors filed their appeals on December 6, 2022. 21 In the Matter of Idaho Power Company’s Application for a Certificate of Public Convenience and Necessity for the Boardman to Hemingway 500-kV Transmission Line, Case No. IPC-E-23-01; In the Matter of Idaho Power Company’s Petition for Certificate of Public Convenience and Necessity, OPUC Docket PCN 5. 22 Case No. IPC-E-23-01, Application at 15 (Jan. 9, 2023). 23 Id. APPLICATION OF ROCKY MOUNTAIN POWER PAGE 14 E. Cost Estimates and Revenue Requirements. Estimates of the cost of the construction or expansion, the number of additional customers to be served by the construction or expansion, the revenues to be derived from the construction or expansion, and of the effects of the construction or expansion on revenue requirements. Mr. Vail’s testimony includes the Company’s confidential estimate for its in-service cost of B2H. Mr. Link’s testimony includes the Company’s economic analysis of the Project, which includes both its estimated costs and revenues. PacifiCorp has the capability to finance the Project using the Company’s internally generated funds and access to external capital markets. While the Company is not seeking ratemaking treatment for B2H at this time, Mr. Link’s testimony includes a forecast of the change in nominal revenue requirement due to B2H. This forecast demonstrates a lower overall revenue requirement through the end of the study horizon in 2042. VI. REQUEST FOR RELIEF Rocky Mountain Power requests that the Commission issue an Order: (1) authorizing that this proceeding be processed under an expedited procedure to issue an order no later than June 30, 2023, aligning with IPC’s CPCN application in Case No. IPC-E-23-01, (2) authorizing Rocky Mountain Power a CPCN to construct the Project as described in this Application, and (3) granting such other authority and authorizations as may be necessary to facilitate the construction of the Project.

In connection with the Goshen Area Asset Exchange (as referenced in Section 3(a)(7) of this table) and the B2H Midline Series Capacitor Project (as referenced in Section 3(a)(12) of this table), PAC and BPA are discussing options to allow PAC the ability to schedule 340 MW from the Buckley substation to the 500kV side of the Ponderosa Transformer Bank 500/230 kV #1 (“Ponderosa 500”) and to concurrently schedule 340 MW from the Summer Lake substation to Ponderosa 500 upon energization of the B2H line and the B2H Midline Series Capacitor Project. I. Contingent upon the conditions set forth below, PAC and BPA desire for the concurrent bidirectional scheduling rights over the Buckley-Summer Lake line to be provided as firm point-to-point transmission service (“PTP service”) pursuant to the terms and conditions in BPA’s Tariff and rate Rocky Mountain Power Exhibit No. 1 Page 2 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 3 of 32 and the B2H Midline Series Capacitor Project. As of the Effective Date, the PAC and BPA understand that such PTP service remains subject to further BPA evaluation. a. BPA’s offer of PTP service may include conditions if such conditions are identified during BPA’s evaluation. Conditions for PTP service are at BPA’s sole discretion and, if required, will be developed consistent with the principles set forth in Section 3(a)(1)(II)(b) so that flows associated with the PTP service over the Buckley-Summer Lake line do not exceed 340 MW in the north-to-south direction and concurrently does not exceed 340 MW in the south-to-north direction during all lines in service. b. As part of the PTP service evaluation, PAC and BPA will also explore options to combine an offer of PTP service with the modification to points of receipt and points of delivery in PAC’s existing PTP service tables (“redirect”) within the Long Term Firm Point-to-Point Service Agreement (No. 04TX-11722) between PAC and BPA, subject to BPA’s Tariff and related business practices including available transfer capability (“ATC”), with a goal to optimize PAC’s transmission service over the Federal transmission system to serve its central Oregon loads (e.g., using a single wheel from a network point of receipt to PAC’s load at Ponderosa 230 or Pilot Butte 230). BPA will apply its long-standing practice to evaluate the ATC impacts of the new PTP service against the ATC impacts of existing service, to include the bidirectional scheduling rights and redirected service. c. BPA may request additional information from PAC. PAC will make good faith efforts to provide such information within 30 days of BPA’s request. d. PAC will submit applicable transmission Rocky Mountain Power Exhibit No. 1 Page 3 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 4 of 32 of BPA’s notice to PAC that such requests should be submitted. e. If BPA determines, in its sole discretion, that BPA can convert the bidirectional scheduling rights to PTP service, BPA agrees to offer PTP service pursuant to BPA’s Tariff and rate schedules. i. The PTP service will be contingent upon and will not be effective before (A) the energization of the B2H line and the installation of the B2H Midline Series Capacitor Project; (B) approval by the Federal Energy Regulatory Commission (“FERC”) of the proposed amendments to the Midpoint-Meridian Agreement discussed in this Section 3(a)(1), per subpart (iii below; and (C) the Goshen Area Asset Exchange set forth in Section 3(a)(7) of this table is completed and all associated agreements are in effect. ii. PAC and BPA will adhere to the applicable requirements set forth in BPA’s Tariff and related business practices, including timelines for execution or amendment of a service agreement. iii. Concurrent with the execution of the PTP service agreements contemplated in this Section 3(a)(1)(I), PAC and BPA will amend Section 4(a) of the Midpoint-Meridian Agreement to remove and otherwise terminate PAC’s bidirectional scheduling rights over the Buckley-Summer Lake Line. f. If BPA offers PTP service that satisfies PAC’s objectives as expressed in this Term Sheet, PAC intends to accept such service subject to the condition regarding FERC approval described below. If following FERC acceptance without material conditions of the arrangements negotiated between BPA and PAC in this Section 3(a)(1)(I), PAC nonetheless fails Rocky Mountain Power Exhibit No. 1 Page 4 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 5 of 32 declines to accept the PTP service or execute a PTP service agreement, then BPA will have no further obligations to provide PAC with the PTP service described in this Section 3(a)(1)(I) or the scheduling rights described in Section 3(a)(1)(II) below. g. PAC and BPA will negotiate in good faith to complete and enter into agreements needed to complete the other conditions set forth in Sections 3(a)(2) through (14) and 3(c) of this Term Sheet, as such conditions are applicable to either Party. h. PAC will seek FERC guidance as necessary and file the proposed amendment to the Midpoint-Meridian Agreement with FERC for acceptance. BPA will reasonably coordinate with PAC to prepare for FERC meetings and submissions. FERC’s unconditioned acceptance shall be a condition to PAC’s obligations as contemplated under this Term Sheet. II. Following either (1) BPA’s determination that it is unable to provide the PTP service to PAC consistent with Section 3(a)(1)(I) above, or (2) FERC’s failure to accept without material conditions the arrangements negotiated between PAC and BPA under Section 3(a)(1)(I) above, BPA will, effective upon energization of the B2H line and the B2H Midline Series Capacitor Project provided that all conditions described below are met, provide PAC with bidirectional scheduling rights over the Buckley-Summer Lake line which give PAC the ability to (A) schedule 340 MW from the Buckley substation to Ponderosa 500 (“North to South schedules”) and (B) concurrently schedule 340 MW from the Summer Lake substation to Ponderosa 500 (“South to North schedules”) (collectively referred to as “scheduling limits”). The concurrent, bidirectional scheduling rights described in the Rocky Mountain Power Exhibit No. 1 Page 5 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 6 of 32 provided pursuant to an amendment to the Midpoint-Meridian Agreement and one or more separately negotiated agreements, that will be effective upon acceptance by FERC and after all conditions set forth in this Section 3(a)(1)(II) are met and will remain in effect until BPA offers PTP service as set forth in Section 3(a)(1)(I). PAC and BPA will work in good faith to satisfy all such conditions consistent with the principles articulated in Section 3(a)(1)(II)(b) below by energization of the B2H line. a. Transmission service to move from the Ponderosa 500 substation. The utilization of the concurrent bidirectional scheduling rights at the Ponderosa substation described in this Section 3(a)(1)(II) is limited to Ponderosa 500. PAC must reserve PTP service from BPA pursuant to BPA’s Open Access Transmission Tariff (“OATT”), business practices, and rate schedules in effect at the time of such reservation to move from Ponderosa 500 to the 230 kV side of Ponderosa transformer bank #1 for delivery to PAC load in central Oregon. b. Principles to guide satisfaction of conditions. i. North to South schedules, South to North schedules, and the associated directional power flows may not exceed the scheduling limits (e.g., 340 MW North to South and, concurrently, 340 MW South to North, under all lines in service). A Power Transfer Distribution Factor (“PTDF”) based methodology (“PTDF algorithm”) and calculator will be used to determine directional power flow. The PTDF algorithm will sum positive flows in the North to South and South to North directions (i.e., schedules and flows are not netted). ii. If, at any time, North to South schedules, South to North schedules, Rocky Mountain Power Exhibit No. 1 Page 6 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 7 of 32 flows exceed the scheduling limits, PAC shall reduce the schedules so that the schedules and directional power flows are within the scheduling limits. BPA can, at BPA’s sole discretion, curtail the schedules in whole or in part to maintain the scheduling limits and to mitigate congestion, such as during outages. iii. Schedules (E-Tags) must contain a single granular source and sink. Sources and sinks (1) cannot be consolidated on a single E-Tag; and (2) must be granular enough to determine the PTDF impact. Sources and sinks that are scheduling points, hubs, or nodes are not sufficiently granular to determine the PTDF impact. iv. PAC may not schedule from sources and sinks for which the PTDF impact has not been determined. PAC will provide BPA with advance notice of sources and sinks with sufficient time for BPA to determine the PTDF impact and, if necessary, to accommodate modifications to tools, systems, and contracts. v. The terms, tools, and protocols associated with the concurrent bidirectional scheduling rights will be structured to minimize to the maximum extent possible any impacts exceeding the scheduling limits (e.g., 340 MW North to South and, concurrently, 340 MW South to North, under all lines in service) that the physical flows associated with the concurrent bidirectional scheduling rights have on the Pacific Northwest AC Intertie (as such transmission facilities are defined in the various PNW AC Intertie-related agreements among PAC, BPA and the other PNW AC Intertie owners, the “NW AC Rocky Mountain Power Exhibit No. 1 Page 7 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 8 of 32 system, as reasonably determined by BPA. c. Conditions to Effectiveness of 3(a)(1)(II) Scheduling Rights i. PTDF calculator. BPA will develop a PTDF algorithm to calculate the directional power flow associated with each source and sink that PAC intends to schedule. PAC and BPA will coordinate to develop, at PAC’s expense, a PTDF calculator that uses the PTDF algorithm and related communication equipment. ii. Agreement on operational terms. After the PTDF calculator is developed, PAC and BPA will work in good faith to develop operational terms, to include the protocols and requirements for monitoring, dispatch, curtailment, reduction of scheduling limits due to outages, and future modifications to stay current with reliability standards, automation, and technological abilities. The operational terms will remain in effect for the duration of the concurrent bidirectional scheduling rights described in this Section 3(a)(1)(II) and will be incorporated into the proposed amendments to the Midpoint-Meridian Agreement or such other agreement as mutually agreed by PAC and BPA. iii. Energization of the B2H Project, including the B2H Midline Series Capacitor Project. iv. The agreements set forth in Section 3(a)(1)(III) below are, to the extent required, accepted for filing at FERC without material conditions. v. The Goshen Area Asset Exchange set forth in Section 3(a)(7) of this table is completed and all associated agreements are in effect. Rocky Mountain Power Exhibit No. 1 Page 8 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 9 of 32 a. Agreement on Principles and Timelines. Following execution of the Term Sheet, PAC and BPA will negotiate and execute an agreement to reflect the objectives, commitments, principles, conditions, and timelines, including negotiation of applicable follow-on agreements for the PTP service described in Section 3(a)(1)(I), and the concurrent, bidirectional scheduling rights described in Section 3(a)(1)(II). With regard to the concurrent, bidirectional scheduling rights described in Section 3(a)(1)(II), the Agreement on Principles and Timelines would include the principles and conditions set forth in Section 3(a)(1)(II) above, and the timelines for development of the PTDF calculator and negotiation of operational terms and protocols. b. Follow-on Agreements. Before energization of B2H and subject to the conditions described above in this Section 3(a)(1) being met, PAC and BPA will negotiate and execute (1) the agreements and amendments referenced in Section 3(a)(1)(I) above, or (2) if BPA is not yet providing PTP service upon B2H energization consistent with Section 3(a)(1)(I) above, then an amendment to the Midpoint-Meridian Agreement to reflect the addition of the concurrent bidirectional scheduling rights, including term, scheduling and directional power flow requirements, usage of the PTDF calculator, and operational terms, all as consistent with Section 3(a)(1)(II) above. PAC and BPA understand that PAC may be required to file amendments to the Midpoint-Meridian Agreement with FERC for acceptance and that the effective date for the agreements referenced above will be upon FERC acceptance without material conditions. IV. Consistent with the “Phase II Joint Study Rocky Mountain Power Exhibit No. 1 Page 9 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 10 of 32 Hemingway (B2H) and Incremental Central Oregon Load” completed on March 23, 2021, upon notice from BPA, PAC will upgrade the existing Meridian Series Capacitor on the 500 kilovolt bus or install an electrically equivalent series capacitor on the PAC section of the Dixonville-Meridian-Klamath Falls-Captain Jack lines in southern Oregon within a reasonable time after receiving the notice. PAC shall be responsible for all costs associated with the upgrade. V. PAC and BPA agree that the proposed modifications to the Midpoint-Meridian Agreement described above are limited in scope to PAC’s bidirectional scheduling rights over the Buckley-Summer Lake line under Section 4 of the Midpoint-Meridian Agreement and do not include BPA’s bidirectional scheduling rights over the Summer-Lake Malin line under Section 4 of the Midpoint-Meridian Agreement. PAC and BPA do not intend to modify, change, alter, or terminate BPA’s bidirectional scheduling rights over the Summer Lake-Malin line set forth in Section 4 of the Midpoint-Meridian Agreement or the General Transfer Agreement between PAC and BPA, originally executed May 4, 1982, as amended. 2. IPC & PAC & BPA New operational agreement between IPC, PAC & BPA Prepare First Draft – BPA: Quarter 3 of Calendar Year 2022 Target Execution Date: Quarter 4 of Calendar Year 2022 IPC, PAC and BPA agree to negotiate in good faith and draft a tri-party operational agreement that will: a. Consider Midpoint-Meridian Agreement Section 5(f); and b. Define the curtailment procedures between NW AC Intertie, Western Electricity Coordinating Council (WECC) Path 14 (Idaho to Northwest), and WECC Path 75 (Hemingway – Summer Lake); and c. Identify conditions for revising the tri- party operational agreement including, but not limited to: i. Engagement with NW AC Intertie Rocky Mountain Power Exhibit No. 1 Page 10 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 11 of 32 ii. In the event the B2H Project and the B2H Midline Series Capacitor Project are not complete and energized by 2027. The Parties will make best efforts to negotiate and target execution of the tri-party operational agreement within one year of the Effective Date of this Term Sheet, with an effective date for the tri- party operational agreement a reasonable time thereafter. 3. PAC & BPA Termination of Existing NITSAs: PAC Trans – BPA Merchant NITSAs (SA Nos. 746, 747) Incorporate into Agreement on Principles and Timelines under 3(a)(1) BPA Network Integration Transmission Service Agreements (“NITSAs”) (PacifiCorp Service Agreement No. 746 and No. 747): BPA and PAC agree to terminate the aforementioned NITSAs upon (1) the completion of the asset purchase and sale between IPC and PAC as detailed in Section 3(a)(5) through Section 3(a)(7) of this table – the Goshen Area Asset Exchange, and (2) the commencement of network service as described in Section 3(b)(1). 4. IPC & BPA & PAC New Agreement: Longhorn Substation Agreements Prepare First Draft – BPA: Quarter 2 of Calendar Year 2022 Target Execution Date: Quarter 3 of Calendar Year 2022 IPC and PAC will fund a portion of the proposed Longhorn substation near Boardman, Oregon, if B2H interconnects at Longhorn. This funding will occur as specified in one or more negotiated Longhorn Substation Agreements between the Parties that is consistent with BPA’s Line and Load Interconnection Business practices and allows for recovery of the network portion of these funds through incremental transmission wheeling revenue. The agreement will: a. include provisions for IPC and PAC to pay a use of facilities charge or other charge pursuant to BPA’s OATT and applicable rate schedules to transact across the Longhorn bus in the future; b. include provisions for IPC and PAC to potentially own, operate and maintain Rocky Mountain Power Exhibit No. 1 Page 11 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 12 of 32 B2H series capacitor at Longhorn, the B2H shunt line reactors at Longhorn, any ancillary equipment required to support those devices, such as switches, bypass breakers (series cap), and insertion breakers (shunt reactor); and c. be contingent upon BPA completing its obligations and responsibilities under NEPA, NHPA, and other requisite environmental compliance laws and making a decision regarding how to proceed (including provisions for IPC and PAC funding upfront at a prorated amount based on cost allocation of Longhorn, BPA’s NEPA, NHPA, and environmental compliance costs). Non-binding cost estimates identified for the potential Longhorn aspects of the B2H Project as of the Effective Date of this Term Sheet are as follows, which all Parties acknowledge and agree are preliminary and may be modified and revised prior to and upon B2H energization: These are estimated costs, charges to be trued up with actual costs. a. Longhorn (base substation) network costs ~$59M. Costs subject to transmission credit. i. IPC 21% ~ $12M (BPA to cover up to $14M of IPC cost) ii. PAC 55% ~ $33M iii. BPA 24% ~ $14M (plus IPC ~ $12M, for total ~ $26M) b. B2H connection to Longhorn Network Bay~$11M. Constructed/Owned/Maintained by BPA. Develop bay 3 with (2) 500kV circuit breakers & (5) 500kV disconnects. Costs subject to transmission credits. i. IPC & PAC 100% c. Customer built (not subject to transmission credits). Including civil work with the reactor and cap costs. Rocky Mountain Power Exhibit No. 1 Page 12 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 13 of 32 5. IPC & PAC New Agreement: Purchase and Sale Agreement for Asset Exchange -potentially utilize the previously developed Joint Purchase and Sale Agreement Prepare First Draft – IPC: Quarter 2 of Calendar Year 2022 Target Execution Date: Quarter 4 of Calendar Year 2022 PAC and IPC would purchase and sell to each other various assets to achieve the objectives identified in Section 3(a)(6) and Section 3(a)(7) of this table. PAC and IPC will seek to first balance the purchase and sale of the transferred assets through the depreciated net book value of such assets and allocation of upgrade costs and, finally, if necessary, will be balanced between IPC and PAC through cash considerations. Details related to Populus – Four Corners assets: These assets will provide IPC ownership on the existing PAC transmission system from Four Corners substation in New Mexico to Populus substation in Idaho. This will include 345 kV transmission lines between the following substations and assets to create a path through each substation: Four Corners, Pinto, Huntington, Camp Williams, Mona, Terminal, 90th South, Ben Lomond and Populus. Consistent with federal processes, IPC and PAC will complete required studies to determine if recent system upgrades result in a possible increase in existing transmission capacity between Borah and Populus to facilitate IPC’s incremental transfer needs associated with this exchange. If determined necessary, IPC and PAC will identify revisions to the JOOA (as defined in Section 3(a)(6) of this table), upgrades, modifications, or other options to meet each party’s commercial needs between Borah and Populus. Details related to Borah/Kinport to Hemingway and Midpoint to Borah/Kinport assets: These assets will provide PAC ownership on the existing IPC transmission system from Borah/Kinport to Hemingway and from Midpoint 500 to Borah/Kinport. This will include 500 kV and 345 kV transmission lines between the following substations and assets to create a path through each substation: Borah, Kinport, Adelaide, Midpoint and Hemingway. Upgrades are required across the Borah West and Rocky Mountain Power Exhibit No. 1 Page 13 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 14 of 32 proposed asset exchange transaction. The cost of these upgrades will be determined in the course of negotiating the proposed asset exchange transaction described in this Section 3(a)(5). Details related to Goshen Area assets: As described in more detail in Section 3(a)(7) of this table, PAC will transfer to IPC certain to-be- determined Goshen areas transmission assets that would allow IPC to provide transmission service to all BPA customers in southeast Idaho currently served by PAC. These assets are being transferred to IPC, from PAC, as part of the negotiations between PAC and BPA as described in Section 3(a)(1) of this table, with the consideration for these assets being the transmission service provided by BPA to PAC as detailed in Section 3(a)(1) of this table. IPC and PAC intend for these Goshen assets to be incorporated into the broader purchase and sale agreement described in this Section 3(a)(5) with a goal of minimizing changes to each company’s transmission rate base. This goal is intended to be facilitated through the allocation of the costs associated with the Borah West and Midpoint West upgrades. 6. IPC & PAC Amendment to Existing Agreement: IPC – PAC Joint Ownership and Operating Agreement (“JOOA”) Prepare First Draft – IPC: Quarter 2 of Calendar Year 2022 Target Execution Date: Quarter 4 of Calendar Year 2022 As part of a transaction transferring assets described in Section 3(a)(5) of this table, IPC and PAC may expand their existing Joint Ownership and Operating Agreement, as amended and restated August 22, 2019 (“JOOA”), to include the following: I. PAC owning 300 MW of west-to-east transmission assets between Midpoint 500 and Borah (transferred from IPC); and II. PAC owning an additional 600 MW of east-to- west transmission assets between Borah and Hemingway (transferred from IPC) - total increases from the current 1,090 MW to 1,690 MW; and III. IPC owning 200 MW of bi-directional transmission assets between Populus, Mona and Four Corners (transferred from PAC); and IV. Other revisions as necessary to facilitate other asset exchanges (e.g., for Goshen area, as Rocky Mountain Power Exhibit No. 1 Page 14 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 15 of 32 described in Section 3(a)(5) and Section 3(a)(7) of this table). 7. IPC & PAC Goshen Area Asset Exchange Part of 3(a)(5) As referenced in Section 3(a)(5) and Section 3(a)(6) of this table, IPC and PAC would negotiate an asset exchange to be effective no later than (i) energization of the B2H line and (ii) commencement of the NITSA between BPA and IPC, as referenced in Section 3(b)(1), that enables BPA to to serve its loads currently in PAC’s East transmission system (Lower Valley Elec., Idaho Falls, Fall River Rural Elec., Lost River Electric, Salmon River Electric, Soda Springs,) (“Southeast Idaho Load Service (SILS) Customers”) with one leg of firm IPC network transmission service. As referenced in Section 3(a)(6) of this table, the Goshen area asset exchange may be wrapped into the existing JOOA framework. IPC, PAC, and BPA agree to make best efforts to plan for service to Idaho Falls that requires only one leg of network transmission from the BPA transmission system, provided such best efforts among the Parties must (1) respect and retain the existing services arranged for Idaho Falls load service between BPA and Utah Associated Municipal Power Systems (UAMPS); and (2) be in line with FERC orders in similar circumstances and accepted by FERC. 8. IPC & BPA New Agreement: Point to Point TSA Prepare First Draft – BPA: Quarter 2 of Calendar Year 2022 Target Execution Date: Quarter 3 of Calendar Year 2022 IPC will acquire up to 500 MW of PTP transmission service from Mid-C to Longhorn subject to the terms of BPA’s OATT, business practices and applicable rate schedules. The duration of the new service must be for an initial service duration of at least 5 years, and sufficient to compensate BPA for BPA’s revenue requirement associated with BPA capital investments to facilitate the transmission service, with the right to rollover service in accordance with the BPA’s OATT and business practices in effect at the conclusion of the initial term. Rocky Mountain Power Exhibit No. 1 Page 15 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 16 of 32 9. IPC & PAC Upon energization of the B2H Project, PAC would not renew its current 510 MW of east-to-west rights on the IPC system (which rights are found in IPC 1st Revised Service Agreement (SA) Nos. SAs 344-346 and 383-384). Consistent with and pursuant to IPC’s OATT, PAC and IPC will coordinate to extend any remaining IPC SAs, enter into new SAs, or take other action as necessary to bridge any SA expiration dates until such time as the B2H project is in-service. 10. IPC & PAC B2H Construction Funding Agreement- related Commitments The B2H Construction Funding Agreement, between IPC and PAC as referenced in Section 3(d) below, and any additional agreements as the Parties determine necessary, will include terms necessary to implement the Agreement to Reimburse BPA’s Removal and Replacement Related Transaction Costs, among IPC, PAC and BPA, dated March 18, 2020 (BPA Contract No. 20TX-16835). IPC, on behalf of the B2H Project, will assure that it coordinates construction of the B2H Project with BPA in a manner consistent with the terms of BPA’s Use Agreement, as amended by Amendment Two (2) to NF(R)-9617, including Exhibits A, B and C, between the United States of America, Dept. of the Navy and the United States of America, Bonneville Power Administration Ptn Secs 13, 23 and 24-T2N- R25E, W.M. IPC and PAC acknowledge that the Removal and Replacement Related Transactions described in Contract No. 20TX-16835 are contingent upon (1) BPA obtaining acceptable service from Umatilla Electric so that BPA may continue to serve Columbia Basin Electric’s load; (2) BPA completing its obligations and responsibilities under NEPA, NHPA, or other requisite environmental compliance laws and making a decision regarding how to proceed; and (3) IPC and PAC moving forward with construction of the B2H Project. 11. IPC & PAC & BPA In conjunction with the termination of the NITSAs i.e Rocky Mountain Power Exhibit No. 1 Page 16 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 17 of 32 BPA Redirect and Assignment of existing PTP transmission service Incorporate into Agreement on Principles and Timelines under 3(a)(1) SAs 746 & 747), following the energization of B2H, BPA will redirect its two 100 MW PTP transmission service agreements (91629850 and 91629500, or any applicable AREFs that supersede or replace them) that it takes from IPC (i.e., IPC 1st Revised SAs 324 & 342) such that the new POR of each SA will be Walla Walla and the new POD for each SA will be Borah. Consistent with and pursuant to IPC OATT, following approval of such redirects by IPC as described above, BPA will assign those redirected reservations to PAC. This redirect and assignment will be delayed by BPA if B2H energization is delayed past 07/01/2026. PAC shall be responsible to pay for all costs associated with 91629850 and 91629500, or any applicable AREFs that supersede or replace them, upon approval of such redirect by IPC and assignment by BPA. 12. IPC & PAC & BPA, with respect to B2H Plus Facilities Expectations IPC & PAC, with respect to B2H Construction Funding Agreement The B2H Project will include the installation of the B2H Midline Series Capacitor Project and development of a remedial action scheme ("RAS"). When considering BPA’s study methodology, the B2H midline series capacitor reduces simultaneous interactions between the NW AC Intertie, central and southern Oregon load service, and WECC Path 14 (Idaho to Northwest). The Parties agree to funding of the B2H Midline Series Capacitor Project as follows: a. IPC: funding 45% of the cost. b. PAC: funding 55% of the cost c. BPA: funding 0% of the cost The Parties will work in good faith to have the B2H Midline Series Capacitor Project in-service when the B2H Project is energized and to document expectations of operation, maintenance, and future reinforcements and upgrades. 13. IPC & PAC B2H Grant or Additional Funding Under IPC and PAC’s existing OATT rate procedures, IPC and PAC will include any United States Department of Energy (“DOE”) grant or additional funding received for the B2H project in the appropriate FERC account provided such account is allocated 100% to Transmission. Nothing in this Term Sheet limits or waives any party’s right to Rocky Mountain Power Exhibit No. 1 Page 17 of 32 Case No. PAC-E-23-01 Witness: Rick T.

IPC & PAC & BPA Permit Funding Agreement Amendment Upon transfer of BPA’s Permitting Interest to IPC identified in 3(b)(3) below, the Permit Funding Agreement will be amended to recognize the re- allocation of the Parties’ Permiting Interests and related funding obligations. b) NITSA Terms and Conditions, NITSA Security Agreement, NITSA Backstop 1. IPC & BPA New Agreements: Network Integration Transmission Service Agreement to serve BPA customers at Goshen Network Integration Transmission Service Agreement to service BPA’s customer at Burley Amendment to currently effective Network Integration Transmission Service Agreements Prepare First Draft – IPC: Quarter 2 of Calendar Year 2022 IPC and BPA will enter into two NITSAs for IPC to provide firm network transmission service to BPA. One NITSA will serve BPA customers at Goshen (replacing what is, as of the Effective Date of this Term Sheet, provided under PAC Service Agreement 746) and one NITSA will serve Idaho Falls (replacing what is, as of the Effective Date of this Term Sheet, provided under PAC Service Agreement 747) (“New NITSAs”). The New NITSAs will be in addition to the existing NITSAs BPA currently holds with IPC for service to BPA’s customers located on IPC’s system (“Existing NITSAs”). The term of BPA’s New NITSAs will be 20-years from energization of the B2H Project, with a renewal or rollover option at BPA’s discretion as required and permitted by FERC a.

IPC & BPA New Agreement: NITSA Security and Risk Backstop Agreement Prepare First Draft – IPC: Quarter 2 of Calendar Year 2022 Target Execution Date: Quarter 3 of Calendar Year 2022 IPC and BPA will enter into an NITSA security and risk backstop agreement (“NITSA Security Agreement”), concurrently with the New NITSA and the purchase and sale agreement referenced in Section 3(b)(3) of this table. Reimbursement If IPC Receives all Permits and Certificates of Public Convenience and Necessity (CPCN) for Construction of B2H IPC will reimburse BPA for the transfer of BPA’s Permitting Interest under the Joint Permitting Agreement in an amount consisting of BPA’s investment in B2H prior to the transfer date (~$25m). BPA will also pay to IPC an additional $10 million upon execution of the New NITSAs and the NITSA Security Agreement with the intent of offsetting overall B2H project costs in IPC’s rate base. The additional $10 million plus BPA’s investment in B2H will be collectively referred to as the “Funded Amount.” IPC will retain the Funded Amount as follows: If and when IPC obtains all necessary CPCNs and permits for the B2H Project (and all appeals, if any, have been resolved), IPC shall have until January 1, 2026 (“Commencement Date”) to commence construction of B2H or to inform BPA of its intent to not pursue construction of B2H. (1) If IPC commences construction of B2H before the Commencement Date, then: a. Interest on the Funded Amount (~$35m) payable by IPC to BPA will accrue from Rocky Mountain Power Exhibit No. 1 Page 20 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 21 of 32 established in the applicable IPC tariff for customer funded projects; b. The Funded Amount and all accrued interest will be repaid to BPA starting year 11 following the energization date (the “Refund Commencement Date”), with repayment amortized over the remaining 10 years of the New NITSAs. i. IPC and BPA will incorporate the interest schedule and payment amortization as an exhibit to the NITSA Security Agreement; ii. If during the term of the New NITSAs BPA defaults on its payment obligations under the New NITSAs, IPC will be entitled to retain for its own account an amount equal to the defaulted payment obligation not to exceed the amount not reimbursed to BPA as of the default date; iii. BPA will not be considered in default for any amount not paid subject to a billing dispute; and iv. IPC may prepay the Funded Amount and interest thereon at any time without penalty. (2) If IPC does not commence construction of B2H by or before the Commencement Date or if IPC informs BPA before the Commencement Date of its intent to not proceed with B2H, then: a. Commencement Date whichever is earlier) to sell its Permitting Interests in the B2H Project; b. No later than the close of the above mentioned 180 days, IPC shall i. from the sale of its Permitting Interest in the B2H Project (if Rocky Mountain Power Exhibit No. 1 Page 21 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 22 of 32 ii. Pay to BPA the $10 million BPA provided to IPC upon execution of the New NITSAs. Risk Backstop if IPC does not Receive all Permits or CPCNs Necessary for constructing B2H. If IPC does not obtain all necessary CPCNs and permits for the B2H Project, or any such CPCNs or permits are overturned on appeal, then (a) IPC will return to BPA the $10 million BPA provided to IPC upon execution of the New NITSAs; and (b) BPA will reimburse IPC for funding the additional 24.24% share of all B2H Permitting and Preconstruction Costs incurred after BPA transfers its 24.24% Permitting Interest to IPC. The reimbursement obligation will not include any costs related to Right of Way option acquisition or exercising Right of Way Options. The risk backstop commitment will remain in place until IPC obtains all necessary CPCNs and permits for the Project (and all appeals, if any, have been resolved). The intent of the backstop is only to assist IPC in mitigating the risk associated with receiving the approvals for the B2H Project; not to assist in mitigating business risk. The risk backstop commitment will be as follows: a. IPC will not compensate or reimburse BPA for costs expended by BPA on B2H prior to the transfer of the Permitting Interest to IPC (i.e., ~$25m BPA has expended to date); b. BPA will reimburse 24.24% of actual B2H Project Permitting Costs incurred after IPC takes over funding 45% of the project. (Current estimates for 2021-2024 – Total B2H Project estimated at $9,125,466 with 24.24% of these costs estimated at $2,212,234); and c. BPA will reimburse 24.24% of actual B2H Project Pre-Construction Costs incurred after IPC assumes funding 45% Rocky Mountain Power Exhibit No. 1 Page 22 of 32 Case No. PAC-E-23-01 Witness: Rick T. Link Contract No. 22TX-17207 B2H Term Sheet Page 23 of 32 2021-2024 – Total B2H Project estimated at $9,403,564 with 24.24% of these costs estimated at $2,279,652). Collectively, these amounts set forth in a. through c. above will be the “Risk Backstop Amount.” The Risk Backstop Amount will be adjusted, as necessary, to the extent that IPC receives grants or forms of other financial assistance from sources other than BPA or PAC. For example, if IPC received a government grant that defrayed the pre-construction costs of B2H, BPA’s 24.24 % share of the pre- construction costs would be reduced accordingly. 3. Transfer of Interest in Joint Permitting Agreement: Prepare First Draft – IPC: Quarter 2 of Calendar Year 2022 Target Execution Date: Quarter 3 of Calendar Year 2022 IPC and BPA will execute a purchase and sale agreement, assignment, and other applicable transfer documents, concurrently with the New NITSAs, NITSA Security Agreement, and any related other agreements necessary, to transfer all of BPA’s Permitting Interest under the Joint Permitting Agreement (and all of BPA’s interest in the assets associated therewith) to IPC in exchange for IPC’s agreement for repayment to BPA of BPA’s investment in B2H through the Joint Permitting Agreement through the effective date of the definitive purchase and sale agreement contemplated in this Section 3(b) (or other date specified therein). The proposed purchase and sale agreement contemplated in this Section 3(b)(3) will contain representations, warranties, and covenants typical of a transaction of the nature contemplated by these proposed terms. The definitive agreements transferring BPA’s Permitting Interest under the Joint Permitting Agreement and related assets will be executed prior to any activities BPA has indicated could impact federal environmental regulatory requirements under NEPA, so as to prevent additional delay in the development of B2H. Following the transfer of BPA’s Permitting Interest (and associated assets) under the Joint Permitting Agreement to IPC, IPC will be solely responsible for funding an additional 24.24% share of all B2H Project Costs thereafter under Joint Permitting Agreement Rocky Mountain Power Exhibit No. 1 Page 23 of 32 Case No. PAC-E-23-01 Witness: Rick T.
