Please provide an overview ofthe Company's operations. 3 A. PacifiCorp provides retail eleclric service to more than 1.9 million customers in the 4 western states of California, Idaho, Oregon, Utah, Washington, and Wyoming. 5 PacifiCorp does business as Pacific Power in Califomia, Oregon, and Washington and 6 as Rocky Mountain Power in Idaho, Utah, and Wyoming. PacifiCorp serves customers 7 with generation, transmission, and distribution facilities located in a ten-state lootprint 8 across the western United States and operates as a single system on an integrated basis 9 to provide low-cost, reliable and affordable service to customers. 10 a. Why is inter-j urisdictional cost allocation necessary for PacifiCorp? 11 A. PacifiCorp recovers the costs of providing retail electric service to customers through 12 retail rates established in regulatory proceedings in each state. To ensure states receive 13 the appropriate allocation of costs and benefits lrom PacifiCorp's integrated system, 14 the collaborative MSP has been used to address allocation issues. This collaborative l5 process has led to the development and adoption ofa series of inter-j urisdictional cost 16 allocation methods over time. l7 a. How long have multi-state cost allocation agreements been used by the states and i8 PacifiCorp? l9 A. Inter-jurisdictional cost allocation methods have been used for over 30 years. They 20 have evolved and been refined over time, with each cost-allocation method allocating 21 to each state a portion of PacifiCorp's total system costs through a combination of both 22 dynamic system factors and state-specific, or situs, factors. Steward, Di - 4 Rocky Mountain Power o o o What cost-allocation method is currently being used in Idaho? In November 2015, parties participating in the MSP agreed to an allocation method known as the 2017 Protocol. The 2017 Protocol was an agreement between PacifiCorp and certain parties, including regulatory agency staff, consumer advocates and other stakeholders in Idaho, Oregon, Utah, and Wyoming, and was approved by those commissions in 2016, The parties to the 2017 Protocol agreed to support commission adoption and use of the 2017 Protocol in all PacifiCorp rate proceedings filed after December 31,2016, up to and including December 31, 2018. The 2017 Protocol provided for a one-year extension through December 31, 2019, which was approved by the state commissions in 2017, extending the 2017 Protocol through December 31, 2019.I The Company requested approval ofthe 2017 Protocol by the Califomia Public Utilities Commission in its 2018 California general rate case, a decision in that case is pending, What have been the principle challenges to the 2017 Protocol that the MSP has tried to address through the recent collaborative effort? For decades, PacifiCoqp has relied on cost allocation methods that dynamically allocate total system costs to states. As demonstrated by nearly three decades of use, the fundamental premise of the 2017 Protocol, and earlier cost allocation protocols, was durability. A bedrock of these cost allocation protocols has been the use of PacifiCorp's system as a single whole: except for distribution, all states were served from a common portfolio of assets, including generation assets, which enabled PacifiCorp to cost- o I 2017 Protocol ertension orders - Oregon, Docket No. UM-1050.

However, state policies across PacifiCorp's six-state service territory are increasingly challenging this bedrock. For example, requirements to remove coal from rates in certain states will necessarily result in some states being allocated the costs and benefits of coal-fueled generation while other states are not. Similarly, diverging state policies related to implementation olthe Public Utilities Regulatory Policy Act of 1978 ("PURPA"), retail choice, and private generation increasingly present challenges to PacifiCorp's long-standing practice ofplanning lor a single, integrated system. When did these challenges begin to emerge? As early as 2015, the parties to the MSP were discussing these challenges. In fact, the 2017 Protocol was negotiated as an interim and timelimited cost-allocation protocol, designed to provide cost allocation stability while allowing time for parties to the MSP to continue to explore alternative cost-allocation protocols to better align with changing state policies. How have the challenges of diverging state policies been addressed in MSP? Since 2016, PacifiCorp and parties to the MSP have analyzed several cost-allocation proposals. Through a robust and collaborative process, the 2020 Protocol responds to diverging state policies through, among other things, a gradual process oftransitioning California, Oregon, and Washington from allocation of costs and benefits of coal- fueled generation resources and a process to allow Idaho, Utah, and Wyoming to take on additional allocation of costs and benefits. This gradual process provides certainry to states that have policies requiring a transition away lrom coal-fueled generation Steward, Di - 6 Rocky Mountain Power o o I 2 3 4 5 6 7 8 eQ. l0 A. l1 12 13 14 15 a. 16 A. 17 l8 19 20 2t 22 a I without limiting the availabitity ofthose same resources to states that wish to continue 2 receiving costs and benefits from coal-fueled generation. 3 MSP Development of the 2020 Protocol 4 Q. Who has participated in the MSP Workgroup meetings? 5 A. Over the past three years, as many as 3 5 organizations have participated in regular MSP 6 meetings, representing regulatory staff from each state commission in the Company's 7 service territory, consumer advocacy groups, multiple industrial and environmental 8 interest groups, state legislators, a coal supplier, and others. Meetings were held every 9 four to eight weeks since late 201 6. The signatories to the 2020 Protocol can be found l0 in Section 10 of the 2020 Protocol in Exhibit No. l- I I a. Did the Company share principles to help guide the reyiew of inter-j urisdictional 12 cost allocation alternatives? 13 A. Yes, PacifiCorp developed a set ofguiding principles to help evaluate development of 14 a transitional approach to cost allocations. The Company's guiding principles 15 established that a new cost-allocation protocol should: 16 . Provide a long-term, durable solution; 17 . Follow cost-causation principles; l8 . Minimize rate impacts at implementation; 19 . Allow for state autonomy for new resource portfolio selection; 20 . Maintain and optimize system-wide benefits and joint dispatch to the extent 21 possible; 22 . Enable compliance with state policies; 23 . Ensure credit-supportive financial outcome; and, Steward, Di - 7 Rock), Mountain Power O o a . Provide the company with a reasonable opportuniry to recover its costs. O. Does the 2020 Protocol meet these requirements? A. Yes, the 2020 Protocol meets the standards articulated in PacifiCorp's guiding principles. a. The Company's guiding principles reference maintaining and optimizing system- wide benefits. What does "benefits" mean in the context of inter-j urisdictional cost allocation? A. Benefits can refer to a variety ofconcepts. For generation resources, benefits may refer to the energy produced, net power costs benefits, capacity benefits, or other operational benefits the resource brings to the operation of PacifiCoqp's integrated system. Renewable generation resources may also contribute benefits in the form ofcompliance with renewable portfolio standards or other reductions in compliance costs associated with environmental regulations. In the context of transmission or distribution assets, benefits may refer to access to markets and the ability to transact in the Energy Imbalance Market, voltage support, or other system or local reliability benefits. These are simply examples of the types of benefrts that are refered to within the 2O20 Protocol under the general term "benefits"; this list is not exhaustive and is intended only to illustrate the broad array ofbenefits at issue. The 2020 Protocol O. Please describe the 2020 Protocol. The 2020 Protocol represents a fundamental shift in how the Company proposes to address inter-jurisdictional cost allocation, with the ultimate goal of moving away from dynamic allocation factors and a common generation resource portfolio to a cost- Steward, Di - 8 Rocky Mountain Power o 2 J 4 5 6 7 8 9 10 l1 12 l3 t4 15 t6 17 t8 t9 20 21 22 23a o 2 J 4 5 6 7 8 9 allocation protocol with fixed allocation factors for generation resources and state- specific resource portfolios. To achieve this goal, the 2020 Protocol uses a gradual transition approach that relies on continuation of the 2017 Protocol with minor modifications that I will discuss in greater detail below-during an interim period. During this interim period, from January l, 2020, until the earlier of resolution of all remaining cost-allocation issues or December 3 l, 2023 (the "Interim Period"), the 2020 Protocol establishes: (l) cost allocation procedures that will be implemented during the Interim Period ("Implemented Issues"); (2) cost allocation procedures that are agreed to but that will not take effect until after the Interim Period ("Resolved Issues"); and (3) cost allocation procedures that Parties to the 2020 Protocol will continue to work to resolve during the Interim Period ("Framework Issues"), including the implementation or resolution of issues surrounding a NPM, resource planning, new resource assignment, limited realignment, special contracts, post-Interim Period capital additions on coal plants and other items. Before the end of the Interim Period, assuming resolution of all Framework Issues, a new Post-Interim Period Method of cost allocation, incolporating the Implemented Issues, the Resolved Issues and the final resolution of the Framework Issues, will be presented to the commissions for approval. This is anticipated to occur no later than yeat-end 2023 . Has the Company prepared an exhibit that provides a timeline for the various components of the 2020 Protocol? Yes. Exhibit No. 2 is a chart reflecting the various issues covered by the 2020 Protocol from 2019 to 2030. Exhibit No. 2 is intended to provide a picture olhow the various IO il t2ol3 14 l5 t6 17 t8 19 204 2t 22A o Steward, Di - 9 Rocky Mountain Power !-J I elements of the 2020 Protocol interact over time, and assuming a resolution of the Framework Issues, the implementation timeline that would occur for the different elements. Does the 2020 Protocol supersede the 2017 Protocol? Yes. However, the primary elements of the 2017 Protocol are reflected in the 2020 Protocol, but with certain modifications for the current situation. How does the Company propose to use the 2020 Protocol? The 2020 Protocol will be used in regulatory filings in all states beginning January 1, 20202, as it provides for the use ofthe modified West Control Area Inter-Jurisdictional Allocation Methodology (.'WCA") in Washington as well as the modified 2017 Protocol method for California" Idaho, Oregon, Utah, and Wyoming. Does the use ofthe 2020 Protocol prejudge prudence or abrogate a commission's responsibility to determine prudence and just and reasonable rates? No. Section I of the Agreement makes clear that the proposed allocation of a particular expense or investment to a state under the 2020 Protocol is not intended to and will not prejudge the prudence ofthose costs or the extent to which any particular cost may be refl ected i n rates . Please provide an overview of the other sections ofthe 2020 Protocol.

Steward, Di - 10 Rocky Mountain Power o I Section 2 - Timeframes and Effective Periods a What is the effective period of the 2020 Protocol? As explained above, the 2020 Protocol is designed to be used by PacifiCorp and Parties for inter-j urisdictional cost allocation in regulatory proceedings or filings in each state during the Interim Period, beginning January 1,2020. Why is a four-year Interim Period necessary? The four-year Interim Period allows time for Parties to continue working towards resolution of several remaining inter-jurisdictional issues that are identified as Framework Issues in the Agreement. The Framework Issues will be critical to any Pos! Interim Period Method. If all of the Framework Issues are resolved before the end of 2O23, can the new method be implemented early? Yes. If all of the Framework Issues are resolved early, PacifiCorp may propose that each commission approve the Post-lnterim Period Method for use in rate proceedings either during or after the Interim Period. In the event the Post-Interim Period Method is approved by December 31, 2022, the Interim Period will end on December 31,2022 and PacifiColp will use the Post-Interim Period Method lor ratemaking purposes beginning January 1, 2023. What happens if commissions do not approve a Post-Interim Period Method or if Parties are unable to reach agreement? If any commission does not approve the Post-Interim Period Method, PacifiCorp will file an altemative proposed allocation method to take effect upon the conclusion ofthe Interim Period for consideration by the commission in that j urisdiction. Parties will be A 1l 0 t2 a A 2 3 4 5 6 7 8 9 l0 o 13A 14 l5 l6 1,7 18 190 20 22 21 A o Steward, Di - 1l Rocky Mountain Power o free to take any position on the Company's proposal or to propose an altemative method. Second, if the Company determines that an agreement cannot be reached by Parties on the Framework Issues or the Post-Interim Period approach, then, the Company will similarly file an alternative proposed allocation method for consideration by the Commission and Parties will be free to take any position on the Company's proposal or to propose an alternative method. lf either the Post-Interim Period Method is denied or delayed or if no agreement can be reached on the Framework Issues, when will the 2020 Protocol terminate? The 2020 Protocol will terminate no later than December 3 1, 2023. Steward, Di - 12 Rocky Mountain Power 2 4 5 6 7 8 9 a A 12A l0 Section 3 - Interim Period Allocation Method ila How will costs be allocated during the Interim Period? The Parties have agreed that the states should continue to use the inter-j urisdictional allocation methodologies, subj ect to certain exceptions, currently being used in 2019. For California, Idaho, Oregon, Utah, and Wyoming this means that the 2017 Protocol will be extended through the lnterim Period, subject to certain exceptions, Section 3.1 of the Agreement includes the specific terms of the 2017 Protocol that will be used under the 2020 Protocol. For Washington, the WCA will continue during the Interim Period, subject to the terms olAppendix F, ls there explicit consideration for the treatment of NPC balancing accounts or other cost recovery mechanisms? Yes. It is important that the allocation method used for the deferral of costs is consistently applied for the collection of the costs from customers. This is key for historical balancing account mechanisms for NPC. Section 3.2.1 of the 2020 Protocol a IJ t4 15 l6 17 l8 lea 20 22 21 A o I addresses this issue and provides that for NPC filings, PacifiCorp will use the allocation methodology in place when the NPC were or will be incurred, to align the timing of the actual costs incurred with the applicable allocation method for cost recovery for that period. The table in Section 3.2.1 summarizes the transition period between the 2017 Protocol and the 2020 Protocol for NPC filings. What modifications to the 2017 Protocol are proposed in the 2020 Protocol? PacifiCorp proposes four modifications to the 2017 Protocol: elimination of the Equalization Adjustment; changes to the Embedded Cost Differential adjustments; changes to treatment of QFs; and changes to the general governance sections of the 2017 Protocol. Changes to the general govemance sections are discussed later in my testimony regarding Section 8. Please explain the changes to the Equalization Adjustment. The Equalization Adjustment addressed in Section XIV of the 2017 Protocol will terminate on December 31, 2019, and no additional Equalization Adjustment amounts will be defened after that date. Collection of deferred Equalization Adjustment balances and any related carrying charges, has been or will be addressed in appropriate state regulatory proceedings. Whflt are the changes to the Embedded Cost Differential adjustment? The 2020 Protocol provides for continuation of a fixed Embedded Cost Differential for Idaho and a capped dynamic Embedded Cost Differential in Oregon through the end of the Interim Period. No Embedded Cost Differential adjustment exists for Utah or Califomia and the Embedded Cost Differential adjustment will terminate in Wyoming Steward, Di l3 Rocky Mountain Power o a A ') 3 4 5 6 7 8 9 t0 t t3 A l4 l1 t2a t5 t6 ).7 l8 a 19A 20 2t o 22 o December 31,2020. Mr. McDougal's testimony provides additional details related to the Embedded Cost Differential adjustments. What are the changes to the cost-allocation of QF power purchase agreements? In the 2017 Protocol, QF costs were system allocated, but the allocations were subj ect to challenge il a state rejected a portion of the costs that exceeded what PacifiCorp would have otherwise incurred acquiring comparable resources. The 2020 Protocol modifies the treatment ol QFs and provides lor a transition in which current QF contracts are system allocated, but future QF contracts are the responsibility ofthe state approving them. Mr. Wilding's testimony provides a detailed description of the treatment of QF contracts. How are new resources treated during the Interim Period? New resources with a commercial operation date before January 1, 2024 will continue to be treated as system resources, and assigned and allocated based on the System Generation factor. New resources, including new resources contemplated in the action plans of the 2019, 2021 or 2023 inlegrated resource plans with commercial operation dates after December 3 l, 2023, will be assigned and allocated through the new resource planning and new resource assignment processes determined through resolution ofthe Framework Issues workgroup during the lnterim Period. The Framework Issues workgroup is made up ofthe signatories to the 2020 Protocol and will work to resolve the Framework Issues and cooperate in crafting and filing the Post-Interim Period Method. Steward. Di - 14 Rocky Mountain Power 2 3 4 5 6 7 8 9 a A l0 o t2A 13 lt Q t4 15 l6 11 t8 l9 20 2t o o 1 Section 4 - Implemented Issues 2 Q. Will certain aspects of the 2020 Protocol be implemented during the Interim 3 Period? 4 A. Yes, certain changes described more fully below are necessary to implement during the 5 lnterim Period. These Implemented Issues are: 6 . States' decisions to exit coal-fueled existing resources; 7 . Reassignment ofcoal-fueled existing resources; 8 . Decommissioning costs; and, 9 . Treatment of QFs. l0 a. Why is it necessary to implement these flspects of the 2020 Protocol during the ll lnterim Period? 12 A. Changing requirements regarding the ratemaking treatment of coal in Oregon and 13 Washington is one driver for the need for a new approach to inter-jurisdictional cost 14 allocation. Even absent state mandates to remove coal from rates, differing views on 15 the longevity of coal-fueled resources has led to divergent depreciable lives for 16 PacifiCorp's coal-fueled generation units across its six states. Some states will reach 17 the end of their depreciable lives for certain coal-fueled generation units within five 18 years of approval of the 2020 Protocol; some coal-fueled generation units, like Jim l9 Bridger Unit 1, will retire within the Interim Period. In contrast to states with mandates 20 to remove coal-fueled generation from rates, Wyoming has adopted a requirement to 21 seek a buyer for coal-fueled generation in Wyoming once the utility decides to retire 22 the unit.r To accommodate these multiple, and olten contradictory, state policies, a o 3 W1'oming Statute rs.ts37-2-133 ard 37-3-l17 Steward, Di - 15 Rocky Mountain Power o o process is necessary in the near-term that allows for some states to orderly exit lrom coal-fueled generation while simultaneously allowing for other states to continue to include coal-fueled generation in rates and to consider whether to increase their allocated share of the costs and benefits of coal-flueled generation. The first three Implemented lssues listed above outline the process that will be used to allow states to set a date-certain for ending any cost responsibility lor or receipt ofbenefits lrom coal- fueled generation units and the process that will be used to allow states to review whether to take on an additional share of the costs and benefits of coal-fueled generation. Critical to this process is the establishment ol decommissioning cost estimates as states that exit coal-fueled generation units before the generating unit is closed are only responsible for paying estimated decommissioning and remediation costs. The process for establishing decommissioning cost estimates are described more fully in the direct testimony of Mr. McDougal. Similar considerations drive the need to move forward with immediate changes to the treatment ofcost allocation for QFs: commission-established avoided costs vary across PacifiCorp's service territory. The 2020 Protocol sets forth a transitional approach for allocating the costs of QFs to the state where the QFs are approved with full situs-allocation ofQFs beginning in 2029. During the transitional period, QFs with executed contracts or legally enforceable obligations as of December 31, 2019 will continue to be system allocated. The energy output ol QFs with executed contracts or legally enforceable obligations after December 31, 2019 will be system allocated based on a reasonable energy price and any costs above the reasonable energy price will be situs assigned to the state approving the QF contract, The details of this process, Steward, Di - l6 Rocky Mountain Power 2 ) 4 5 6 7 8 9 l0 12 1l t3 l5 1.7 14 o 16 18 l9 20 2t 22 -LJo o including valuation and NPC impacts are addressed in more detail in the direct testimony of Mr. Wilding. How does the 2020 Protocol address certain stateso interest in exiting coal-fueled Interim Period Resources earlier than the Company's currently anticipated operating lives? Where possible, the 2020 Protocol seeks to put states on the same path with respect to operational lives, particularly for those coal-fueled Interim Period Resources that the Company currently anticipates will close before 2030. To the extent there is a common closure date, each state that is assigned and allocated a portion ol the coal-flueled Interim Period Resource at the time of its closure will continue to be allocated its share of any remaining costs, including actual decommissioning costs. lf a state issues an order to exit a coal-fueled resource on a date earlier than anticipated operational closure, the exiting state is responsible for its allocation of the coal-fueled Interim Period Resource's net plant balance and associated costs as ofthe date ofexit. The state is also responsible for accruing an allocation of decommissioning costs as described in Mr. McDougal's testimony. For states where the costs and benefits of coal-flueled Interim Period Resources must be removed from rates by a date certain, the Company will propose a ratemaking treatment for all allocated costs such that costs and benefits remain matched in customer rates. Does the 2020 Protocol establish closure dates for any Interim Period Resource or change the Commission's oversight of the Company's decisions relative to the operating lives of Interim Period Resources? No. The 2020 Protocol does not mandate the closure ol any resource. It establishes a Steward, Di - l7 Rocky Mountain Power 2 J 4 5 6 7 8 9 a A l0 o il l5 t2 l3 t4 l6 t8 l9 204 2l 22 11 23Ao a I process lor states to diverge from the use of common resources over time. The 2020 Protocol identifies dates when certain states expect to no longer participate in a common resource, which are needed to establish key processes, but it in no way affects PacifiCorp's responsibility to prudently make decisions about the operation olits assets and does not limit or otherwise affect commission oversight. What mechanism does the 2020 Protocol establish for those states choosing to exit coal-fueled Interim Period Resources before a decision by the Company to close the resource? Section 4.1 ofthe 2020 Protocol outlines a process by which state commissions may issue "Exit Orders"r which provide for specific "Exit Dates"s, after which the state would no longer receive any benefits or be subject to any new costs related to that resource. Exit Orders may be established through the approval ofthe 2020 Protocol, in depreciation dockets, general rate cases, or other appropriate regulatory proceedings. What actions follow the issuance of an Exit Order for a specific coal-fueled Interim Period Resource by one or more states? An Exit Order triggers certain actions identified in the 2020 Protocol, including the establishment of decommissioning cost obligations for exiting states, a potential process lor the determination of capital addition responsibility, and a process flor the consideration of reassignment of the freed up capacity to other states that have not issued Exit Orders. The 2020 Protocol requests that sufficient time, at least four years, 2 J 4 5 6 l 8 o o A 10 11 t2ol3 t4a t5 16A l7 18 19 20 { Exil Order mcans an ordcr entered b1- a state commission approving the discontinuation ofthe use of an cristing resourcc and c\clusiol of costs and benefits of tlut resource from customer rates b,y tlL11 state on a date ccrlain.

Steward, Di - l8 Rocky Mountain Power t o I 2 is provided from the issuance of an Exit Order to the Exit Date to allow for reassignment ofthe exiting state's share ofthe coal-fueled Interim Period Resource to be considered by other states. The Exit Order alone does not provide for reassignment, or any associated shift in responsibility for future operation and maintenance or capital costs. Reassignment of costs and benefits must be approved by states without Exit Orders in order for cost responsibility to shift among states and for benefits of the resource to accrue to a different state. What Exit Dates does the 2020 Protocol propose, and for which states? The 2020 Protocol identifies prospective Exit Dates for Oregon and Washinglon that allow for compliance with state statutes regarding removal of coal-related costs and benefits from rates. The 2020 Protocol establishes several different groupings of coal- lueled Interim Period Resources: the first group of resources for which the Company assumes common operating lives for all states before 2030 where the states would continue to share in the cost responsibility; the second group ofresources for which the proposed Oregon Exit Dates are identified ranging from 2023 to 2027; the third group of resources for which the proposed Oregon Exit Dates are identified ranging from 2028 to 2029; fourth, the 2020 Protocol addresses the treatment of Exit Orders for Washington; and finally, it addresses a process to establish a recommendation by the Company on the operating life for the Hayden units. Steward, Di - 19 Rocky Mountain Power a A J 4 5 6 7 8 9 l0 a ll IJ t2 t4 l5 l6 18 t9 17 o o How does the 2020 Protocol treat coal-fueled Interim Period Resources not operated by PacifiCorp? With the exception of Hayden,6 the Company and Oregon Pafties agree to support certain Exit Dates for coal-fueled Interim Period Resources not operated by PacifiCorp, and to make best efforts to effectuate Closure. lf Closure ofa coal-fueled Interim Period Resource not operated by PacifiCorp is not effectuated by the Oregon established Exit Date, Oregon Parties will have the option to either to take an allocation and assignment of the costs and benefits of such unit lor one additional year lollowing the specified Exit Date; or discontinue taking an allocation and assignment ofthe costs and benefits ofsuch unit as ofthe specified Exit Date. In either case, Oregon will be allocated actual Decommissioning Costs if Closure of the unit is effectuated within such one-year period, or lor Cholla Unit 4 by January 1, 2023. If Closure is not within the one-year period, or January l, 2023 for Cholla Unit 4, an estimate ol decommissioning costs will need to be established. Please address the treatment of coal-fueled lnterim Period Resources for Washington. Washington's Senate Bill 5116, the Clean Energy Transformation Act ("CETA"), requires an exit from coal-fueled Interim Period Resources by December 3 1 , 2025. The Washin5on Utilities and Transportation Commission's approval of the 2020 Protocol will constitute an Exit Order for Jim Bridger Unit 1 by December 31,2O23, consistent with the 2019 lntegrated Resource Plan, and for Jim Bridger Units 2 through 4 and Steward, Di - 20 Rocky Mountain Power o o 6 Haldcn is a coal-fueled Interim Pcriod Resource that is not operated by Pacificorp.

The Framework Issues process contemplates a potential "Limited Realignment"T of Interim Period Resources, such that Washington's System Generation-Fixed (.'SGF") factor allocation of coal-fueled Interim Period Resources may be exchanged for other Interim Period Resources, including natural gas-fired Interim Period Resources. Exit Orders will only be required for the coal-fueled Interim Period Resources recognized by the WCA method as serving Washington customers, but the Limited Realignment process will address the exchange of all Interim Period Resources. How do the coal plant lives reflected in the 2020 Protocol compare to what is currently approved in each state? Appendix E provides a table reflecting commission-approved depreciable lives in effect as of October 1, 2019, and the Company's proposed depreciable lives for coal- fueled Interim Period Resources in pending depreciation dockets as filed in September 2018. This Appendix is provided for informational purposes for comparison to the lives reflected in Section 4. I of the 2020 Protocol. If the Idaho Public Utilities Commission approyes the 2020 Protocol, what does it mean in relation to the coal plant lives in pending depreciation dockets? The Company is in discussions with parties in the pending depreciation dockets in each state to recommend any modifications necessary for depreciable lives, as well as decommissioning changes, for Commission consideration, In Oregon, the Company 2 J 4 5 6 7 8 9 10 lla o t2 I5 16 21 13A t4 17 20A 184 l9 7 As defined in Appendix A- "Limited Realignment" meals the assigrunent of Interim Period Resources among PacifiCorp states that diffcrcnt from assignmcnl using thc SGF Factor.

Once a state issues an Exit Order, what does the 2020 Protocol contemplate for next steps by the Company? After receipt ofany Exit Order, the Company has the responsibiliry to analyze whether it is reasonable to continue to operate the affected coal-fueled Interim Period Resource for customers in one or more of the states without Exit Orders. PacifiCorp will file its analysis and recommendations in the other states, as outlined in Section 4.2, Reassignment of Coal-Fueled Interim Period Resources. Based on its analysis, PacifiCorp may propose reassignment ol a greater share of the coal-fueled Interim Period Resource to another state or multiple states to match state load and resource balance, or propose a new Exit Date to the other states. PIease explain the timeline for Reassignment filings. For Exit Orders received by December 15, 2020, with an Exit Date on or before December 31, 202'7 , the Company will aim to provide its analysis and recommendations by February 1, 2021. For Exit Orders received by December 31, 2023, with an Exit Date lrom January 1,2028 to December 31,2029, the Company will aim to provide its analysis and recommendations by June 30, 2024. To the extent possible, the Company will file in all states without Exit Orders at the same time, and should the Company not expect to meet these filing guidelines, it will provide formal notice and explanation to the parties to the 2020 Protocol, Should additional Exit Orders not specifically contemplated in the 2020 Protocol be issued, the Company will provide such analysis and recommendations to the States without Exit Orders within 1 six months of receiving the Exit Order, Finally, the Company will make a supplementary filing in each state without Exit Orders within 60 days of the last commission order. This filing will summarize each Commission order, and recommend a path forward consistent with all of the orders. In the event that each state with Exit Orders accepts the Company's recommendation that they take an additional share ofcapacity from a given coal- fueled Interim Period Resource, such that the resource's capacity is fully assigned, what would follow? The Company's supplementary filing in each state without Exit Orders will characterize the reassignment ofthe capacity, along with the new Assigned Production ("AP") factor percentages for that resource, as explained in Appendix C, used to allocate all associated costs and benefits, consistent with the Commission orders. Should the various Commission orders request more capacity of a given coal-fueled Interim Period Resource than is available, the supplemental filing will recommend a pro-rata reassignment consistent with each commission order. How does the 2020 Protocol address a scenario in which states do not collectively accept 100 percent of a coal-fueled Interim Period Resource that is recommended for reassignment? In that case, the Company's supplemental filing will either make a recommendation on how to handle the unassigned capacity, or will make a recommendation that state commissions should issue Exit Orders for the coal-fueled Interim Period Resource.

Pending resolution of the Framework Issues and approval of the Post-Interim Period Method, the lollowing issues are Resolved Issues that will be implemented as part of the Posrlnterim Period Method: allocation ofgeneration costs and fixed assignment of new resources; transmission costs; distribution costs; system overhead costs; administrative and general costs; other allocation issues; demand-side management; and state-specific initiatives. These issues represent critical components of a durable cost-allocation protocol and resolution was based generally on continuing the current cost allocation treatment of these cost components. The direct testimony of Mr. McDougal addresses each of the Resolved Issues in greater detail. 2 J 4 5 6 7 8 9 a t0 o lt 15A 13a 1,2 Section 6 - Framework Issues 14 What are the Framework Issues identified in the 2020 Protocol thflt need to be resolved for the Post-Interim Period Method? The following Framework Issues are identified in the 2020 Protocol lor continued discussion during the Interim Period: . Resource planning and new resource assignment-long-term resource planning on a total system basis while assessing state-specific resource portfolio needs and the process for assignment of shares of new resources by state. . NPC and the NPM-treatment of NPC and the transition to the NPM. . Special contracts-cost allocation treatment for special contracts. . Limited realignment-potential realignment of a limited portion of existing coal-fueled generation and a limited number of natural gas units. r6 1.7 ?0 l8 t9 2l 22 O Steward, Di - 24 Rocky Mountain Power o 1 . Post-lnterim capital additions-a process for determining cost allocation for 2 capital investments made in existing resources where states have different Exit 3 Dates. 4 Q. Why do the Framework Issues require additional time to resolve? 5 A. Most of the Framework Issues represent a significant change to the way the Company 6 historically plans for its system and assigns costs and benefits. Since 2017, Parties have 7 spent significant time discussing issues related to resource planning, new resource 8 assignments, allocation of NPC and the implementation of a NPM. Despite these 9 discussions, the complexity of these issues, combined with the potential impacts on l0 PacifiCorp's actual operations, require additional time for the Company and the Parties 11 to develop a mutually agreeable proposal, Each ofthe Framework Issues are described 12 in greater detail below. 13 Resource Planning and New Resource Assignment 14 a. How does the 2020 Protocol address resource planning and new resource 15 assignment? 16 A- The 2020 Protocol recognizes the need for a new long-term resource planning process 17 for the post-Interim Period that will need to address how to continue least-cost, least- 18 risk planning for the entirety ofPacifiCorp's integrated system while also identifying 19 individual state load and resource balances and accommodating individual state 20 policies. In addition to a new long-term resource planning process, the post-Interim 2l Period will also require a process for the determination ol states' fixed share of new 22 resource acquisitions. The details ofboth new processes have been discussed at length 23 in MSP meetings over the last two years; however, additional time is necessary to fully Steward, Di 25 Rocky Mountain Power o O o I develop robust and durable proposals for processes that are fundamental to 2 PacifiCorp's operations. 3 Net Power Costs and Nodal Pricing Method 4 Q. IIow does the 2020 Protocol address NPC in the post-Interim Period? 5 A. During the post-Interim Period, states will no longer participate in a common resource 6 portfolio and as a result NPC will no longer be dynamically allocated. The NPM, as 7 described in the Memorandum of Understanding signed by Parties in July 2019, 8 attached as Appendix D to the 2020 Protocol, is intended to implement an intra- 9 company nodal pricing regime that allows states to pursue different portfolios, while l0 maintaining the benefits of system dispatch as much as practicable. This is a complex 1 1 issue and there are still items to be resolved before the NPM can be used for ratemaking, 12 and as such, the NPM is a Framework Issue in the 2020 Protocol. The direct testimony l3 of Mr. Wilding addresses the NPM in greater detail. 14 Special Contracts 15 O, How does the 2020 Protocol address Special Contracts? 16 A. As discussed more fully in the testimony of Mr. McDougal, the allocation treatment '11 for Special Contracts does not change from the 2017 Protocol. For the post-Interim 18 Period, the Company has committed in the 2020 Protocol agreement as part of the 19 Framework to continue to work in good faith with the Special Contract customers to 20 develop one or more proposals for consideration by the Parties on the treatment of 2l Special Contracts' loads, costs, and benefits. Steward, Di - 26 Rocky Mountain Power O o o I Q. Does the 2020 Protocol agreement establish a timeframe to present proposals on 2 the treatment of Special Contracts to the Parties to the Agreement? 3 A. Yes. The Company will make best efforts to present a proposal to Parties by September 4 l, 2021, with the intention of incorporating a resolution into the Post-lnterim Period 5 Method. 6 Limited Realignment 7 Q. Please explain Limited Realignment and how it applies in the Interim and post- 8 Interim Periods? 9 A. Limited Realignment is a reassignment ol resources alnong states at a point in time to l0 address Washington's recently-enacted CETA, while appropriately valuing the 11 exchange of rate based assets among the states. Washington's CETA requires, among 12 other things, coal-fueled generation to be removed from rates by December 31,2025. l3 The purpose of Limited Realignment is to address Washington's eight percent shares 14 of coal-fueled resources through trades with other states. CETA also requires all 15 electricity retail sales to be from non-emitting or renewable resources by 2045. A 16 Limited Realignment proposal may address natural gas fired units in addition to coal- 11 fueled generation. 18 a, Does the 2020 Protocol provide a specific Limited Realignment proposal or 19 timeframe for resolution of Limited Realignment? 20 A. No. The details of the Limited Realignment will be discussed amongst the Parties 2l during the Interim Period. I Based on a total PacifiCorp sl'stem-allocation Yi$r' Steward, Di - 27 Rocky Mountain Power o a o o a Steward, Di 28 Rocky Mountain Power 1 Q. Does the 2020 Protocol address post-Interim Period capital additions to coal- 2 frueled resources with Exit Dntes that are different than the depreciation lives in 3 other states? 4 A. Yes, as pan ofthe Framework Issues. The 2020 Protocol includes a straw proposal to 5 address how incremental capital investments would be treated in cost allocations for 6 existing coal-fueled resources. The straw proposal, which Parti es have agreed to 7 evaluate but have not accepted, addresses the allocation of costs based on the timing of 8 incremental capital in relation to a state's Exit Date. The Framework Issues Workgroup 9 will continue to work through the details of this straw proposal during the Interim 10 Period. I I Section 7 - Gains and Losses 12 a. How does the 2020 Protocol address the allocation ofgains or losses from the sale 13 of assets? 14 A. Section 7 provides that the allocation ofgains or losses lrom the sale of Company- 15 owned assets will be based on the assignment ofthe asset at the time ofthe sale, unless 16 the asset has been under that assignment for less than 12 months prior to the sale, in 17 which case any gains or losses would be allocated based on the prior assignment shares. 18 Section 8 - Governance 19 a. What are the key governance provisions in the 2020 Protocol? 20 A. First, the 2020 Protocol establishes two workgroups: the Framework Issues Workgroup 2l and the MSP Workgroup. The Framework Issues Workgroup is made up of the 22 signatories to the 2020 Protocol and will work to resolve the Framework Issues and 23 cooperate in crafting and filing the Post-lnterim Period Method. The MSP Workgroup o 1 will be convened as needed by any party to resolve an allocation issue not specifically 2 treated by the Framework Issues Workgroup in its limited scope. 3 Second, under the 2020 Protocol, holding an annual Commissioner Forum is 4 optional and may be convened by the Parties or commissions as deemed necessary. 5 Third, Parties may only propose changes to the 2020 Protocol based on changed 6 circumstances. A Party wishing to propose a change may bring a proposal to the 7 Company, which will be responsible for circulating the proposal among Parties and 8 scheduling meetings as needed to resolve the issue or concern. Additionally, non-party 9 stakeholders may likewise propose changes to or replacement of the 2020 Protocol, l0 however, such proposals would first require a convening of the MSP Workgroup to l1 address such concerns. 12 Finally, Section 8.6 provides details regarding the interdependency among 13 Commission approvals, establishing that any approval by a given Commission is 14 contingent upon the 2020 Protocol being approved unaltered by other Commissions. 15 Section 9 - Compliance with Resource Laws 16 a. Please explain Section 9. 17 A. Section 9 simply asserts PacifiCorp's determination that the 2020 Protocol complies l8 with all relevant state statutes, and should that change, the Company will convene either 19 the Parties or the MSP Workgroup, as appropriate, to address the issue. 20 Recommendation 21 a, Please summrrize the Company's recommendation. 22 A. The Parties to the 2020 Protocol have spent considerable time and effort investigating 23 inter-jurisdictional cost-allocation methodologies and approaches to respond to the Steward, Di - 29 Rocky Mountain Power o o o 2 J 4 5 6 7 8 9 needs and interests ofthe stakeholders. The 2020 Protocol has been negotiated in good faith as an integrated, interdependent agreement that balances the interests of the Parties. Accordingly, PacifiCorp respectfully requests that the Commission approve the 2020 Protocol, as filed. The Company also requests that the Commission establish a schedule that will allow for a hearing or decision as soon as practicable to enable the Company and Parties to reflect the 2020 Protocol in ratemaking proceedings in 2020 and continue with discussions on the Framework Issues. Does this conclude your direct testimony? Yes. a A o Steward, Di - 30 Rocky Mountain Power O
