My name is Justin B. Farr. My business address is 1407 West North Temple Street, Suite 330, Salt Lake City, Utah 84116. I am currently employed as Assistant Revenue Requirement Manager. Qualifications Briefly describe your education and business experience. I have a Bachelor of Science degree in Economics and a Master of Business Administration degree from the University of Utah. I began employment at PacifiCorp in October 2013 and have held various positions within finance and regulation. Prior to employment at PacifiCorp, I was employed for eight years at Energy Strategies, LLC and between 2017 and2019l led financial planning and analysis at Magnum Development. Please explain your responsibilities as Assistant Revenue Requirement Manager. My responsibilities include the calculation of the Company's revenue requirement, the preparation of business plan regulatory results and the preparation of the Company's Renewable Energy Credit ("REC") filings in various states. Have you testified in previous proceedings? Yes. I have provided testimony in regulatory proceedings in Utah. PURPOSE OF TESTIMONY What is the purpose of your testimony? I explain and support the Company's request, through this Energy Cost Adjustment Mechanism (*ECAM"), for recovery of collectively $17.7 million before carrying Farr, Di-l PacifiCorp 2 J charge, for projects authorized to be included and deferred through the approved Resource Tracking Mechanism (*RTM").These amounts are included in the ECAM as shown in Mr. Jack Painter's Testimony, Exhibit l, line 33. RESOURCE TRACKING MECHANISM Please briefly describe the background and purpose of the resource tracking mechanism (*RTM'). In Case No. PAC-E-17-06, this Commission approved a stipulation allowing the Company to use the RTM as a component of the ECAM to recover the repowering costs of certain Company-owned wind generation assets ("Repowered") and incremental energy production.l Per the stipulation, the RTM and ECAM capture the costs and benefits of the Repowered wind facilities until they are recovered in base rates through a general rate case. On July 20,2018, the Commission approved a stipulation in Case No. PAC-E- 17-07 allowing the Company to use the RTM and ECAM to track new investment, energy production, and Production Tax Credits ("PTCs") associated with the Aeolus- to-Bridger/Anticline transmission line and the Ekola Flats, TB Flats I and II, and Cedar Springs wind projects, and related network upgrades (collectively "Energy Vision 2020 projects"), subject to a cap on the total annual costs set to the amount ofannual project benefits.2 4 5Q. 6 7 8 9 A I In the Matter of the Application of Rocly Mountain Powerfor Binding Rotemaking Treotmentfor llind Repowering, Case No. PAC-E-17-06, Stipulation (November 24,2017); OrderNo. 33954 (December28,2017). 2 In the Matter of the Application of Roclcy Mounlain Power for a Certi/icate of Public Convenience and Necessity and Binding Ratemaking treatmentfor New Wind and Transmission Facilities, Case No. PAC-E- 1707, Stipulation at 3, fl 9 (May 9,2018); Order No. 34104 (July 20,2018) (approving May 9 stipulation).j In the Matter of Rocly Mountain Power's Application to Increase lts Rates and Charges in ldaho andfor Approval of Proposed Electric Service Schedules and Regulations, Case No. PAC-E-20-03, Order No. 34884 at 8 (December 31,2020) ("We further find it reasonable to include Foote Creek I and Pryor Mountain wind projects in the RTM.") Farr, Di-2 PacifiCorp l0 ll t2 l3 t4 l5 l6 t7 l8 l9 2 3 4 ln Case PAC-E-20-03 the Commission approved similar treatment for the Pryor Mountain and Foote Creek I wind resources, matching costs and benefits with costs capped at the benefit level.3 Which projects are included in the RTM and this ECAM? The RTM is split into three parts, shown as Exhibit 4a,4b, and 4c to account for the differences between the sefflement for Repowered wind assets approved as part of Case No. PAC-E-17-06, the settlement for the Energy Vision 2020 projects approved as part of Case No. PAC-E-17-07, and the inclusion of Pryor Mountain and Foote Creek I as approved in Case No. PAC-E-20-3. Below is a description of the assets included in the exhibits. o Exhibit 4a includes the Repowered wind projects. The Repowered projects produced an Idaho-allocated net benefit of $2.57 million. o Exhibit 4b includes the Energy Vision 2020 projects. Together these projects produced an Idaho-allocated net benefit of $2.43 million. o Exhibit 4c includes the Pryor Mountain and Foote Creek I wind projects. These combined wind projects produced an Idaho-allocated net benefit of $1.24 million. The combination of these projects produced an ldaho-allocated net benefit of $6.24 million for customers. 3 In the Matter of Roclcy Mountain Power's Application to Increase hs Rates and Charges in ldaho andfor Approval of Proposed Electric Service Schedules and Regulatiors, Case No. PAC-E-20-03, Order No. 34884 at 8 (December 31,2020) ("We further find it reasonable to include Foote Creek I and Pryor Mountain wind projects in the RTM.")

A a. l0 ll t2A l3 t4 l5 l6 t7 l8 19 Has the Company calculated the deferral for these projects under the RTM guidelines that were agreed to in the stipulations and approved by the Commission? Yes. The deferral calculations follow the design and operation of the RTM as approved in final Order Nos. 33954,4 34l\4,s and 34884.6 The RTM, along with the ECAM, will capture and match all the costs and benefits of the included projects through December 31,2021, at which time the RTM will no longer be necessary because the capital costs will be recovered in base rates. What are the costs and benefits associated with Repowered wind, Energy Vision 2020, Pryor Mountain and Foote Creek I that the Company has included in the RTM deferral? The Company has included the following items in the RTM on a monthly basis beginning when a project is placed into service: . The pre-tax return on investment; . Operation and maintenance expense; . Depreciationexpense; . Property taxes; . Wind taxes, if assessed; . Net Power Cost ('NPC") benefits; J 4 5 6 7 8 9 a In the Matter of the Application Roclry Mountain Powerfor Binding Ratemaking Treatmentfor lYind Repowering, Case No. PAC-E-I7-06, Testimony of Jeffrey K.

Has the Company prepared an exhibit showing the calculated amount of the deferral under the approved RTM guidelines? Yes. Exhibit No. 4a, 4b and 4c show the calculation of the December 31, 2021 RTM deferral balance which results in a $17.7 million charge to be collected from customers through the ECAM. Line 18 of Exhibit No.4a and Line 17 of Exhibit No.4b and Exhibit No.4c show that the projects included in the RTM produced a net revenue requirement of $3.1 million. Why is the Company seeking recovery of $17.7 million through the ECAM? The RTM was approved to match all the costs and benefits associated with the approved projects and pass those onto customers. Absent the RTM, the ECAM only captures some of the benefits and does not include any of the costs incurred to produce those benefits. The ECAM will retum to customers 100 percent ofthe PTCs of $13.1 million, and 90 percent ofNPC benefit of $10.9 million, shown on lines 2l and24fromExhibit 4a and lines 20 and 23 from Exhibit 4b and Exhibit 4c, respectively. Combined, the ECAM would return to customers $24.0 million of benefits, absent the RTM. Due to the sharing band in the ECAM, l0 percent of the NPC benefits would not have been passed onto customers absent the KIM. Further, the ECAM does not capture any of the costs incurred by the Company to Repower the wind facilities and build the Energy Vision 2020, Pryor Mountain, and Foote Creek I wind projects. The purpose of the RTM is to capture those costs and match them with the benefits. The $6.25 million, Farr, Di-5 PacifiCorp 6 7 8 9 2 J 4 5 6 7 shown on line 27 of Exhibit 4, represents Idaho's share of the net benefit produced by these projects. The $17.7 million RTM deferral allows the Company to match and recover the net costs associated with these projects that generate the $24.0 million energy and PTC benefits included in the ECAM. a. Has the Company included a carrying charge on the RTM deferral balance in Exhibit No.4? A. No. Since the RTM deferral balance is subject to the same carrying charge as the other ECAM components, the monthly RTM deferral balance is summed with those other ECAM components and the carrying charge is calculated on the total deferred balance. a. What is the revenue requirement that is deferred for consideration in the next rate case? A. The settlement in Case No. PAC-E-17-07 states that "Any costs above this cap will be deferred as a regulatory asset for recovery to be set in the next general rate case."7 The settlement in Case No. PAC-E-20-03 has similar language, subject to a prudency review.8 Based on the language in these settlements, the Company is deferring for recovery in the next general rate case $2.7 million in202l on line 24.5 of Exhibit 4b, plus the $1.6 million beginning balance as shown on line 33 of Exhibit 4b from Case No. PAC-E-21-07, for a combined $4.3 million on line 35 of Exhibit 4b. In addition, the Company is deferring and will seek recovery in the next general rate case 7 In the Matter of the Application of RoclE Mountain Power for a Certificate of Public Convenience and Necessity and Binding Ratemaking treatmentfor New Wind and Transmission Facilities, Case No. PAC-E- 1707, Stipulation at 5, !f 14 (May 9,2018); OrderNo. 34104 (July 20,2018) (approving May 9 stipulation). 8 In the Matter of Rocly Mountatn Power's Application lo Increase its Rates and Charges in ldaho andfor Approval of Proposed Electric Service Schedules and Regulations, Case No. PAC-E-20-03, Order No. 34884 at 8.
