PAC-E-25-02 OF ROCKY MOUNTAIN POWER FOR ) AUTHORITY TO IMPLEMENT CHANGES ) AMENDMENT TO THE TO NON-LEGACY CUSTOMER ) APPLICATION OF ROCKY GENERATORS ) MOUNTAIN POWER Rocky Mountain Power, a division of PacifiCorp ("Company" or "Rocky Mountain Power"), in accordance with Idaho Code §61-502 and §61-503, and Rules of Procedure 52 and 66 respectfully submits this amendment ("Amendment") to its February 7, 2025 application ("Application")to the Idaho Public Utilities Commission("Commission")which is requesting the Commission approve the Company's proposed changes to its on-site self-generation Electric Service Schedule 136 ("Schedule 136") tariff in accordance with Order No. 36286 and approve the Company's proposed export credit rate methodology. Specifically,the Company's Application requested the Commission approve: (1) an export credit rate for customers on Schedule 136 beginning October 1, 2025, (2) an increased cap for non-residential customers to 2,000 kW, (3) annual updates to the export credit rate, and (4) updated Schedule 136 tariff incorporating the changes reflected in this application. Through the course of discovery and communications with Commission Staff("Staff'), the Company became aware of two necessary adjustments, requiring the Company to file this Amendment.These adjustments are explained Section II below.In support of this Amendment, the Company states as follows: Amendment to the Application of Rocky Mountain Power Page 1 I. BACKGROUND A. Case History and Procedural Schedule 1. On February 7, 2025 the Company filed its Application and on February 27, 2025 the Commission issued a Notice of Application and Notice of Intervention Deadline,giving parties until March 20, 2025 to intervene. No party filed a Petition for Intervention and on March 25, 2025, the Commission issued a Notice of Parties that included PacifiCorp and Staff. On June 17, 2025, the Commission issued a Notice of Modified Procedure and issued the schedule shown in Table 1 below. On July 15 and 16, 2025, Staff held its virtual public workshops. Since the filing date of the Application, approximately 146 public comments have been submitted and posted to the Commission's website under this case. Table 1: PAC-25-02 Procedural Schedule Item Date Virtual Public Workshop July 15, 2025, from 6:00-8:00 pm Virtual Public Workshop July 16, 2025, from 12:00-2:00 pm Comments Due August 14, 2025 Virtual Customer Hearing August 19, 2025, from 4:00-7:00 m Reply Comments Due September 3, 2025 B. Production Requests 2. On June 3, 2025 Staff issued its third Production Request ("PR") set to the Company which include PR numbered 9 through 14. In preparation for its response to PR 11, and as more fully described below, the Company discovered one of its worksheets did not define the winter and summer seasons appropriately. In its June 24, 2025 response to PR 11, the Company explained this error, and also provided a corrected worksheet which included an adjustment identified as the "Season Adjustment". 3. While reviewing the Company's response to PR 11, Staff identified time zone and hourly inconsistencies on the Company's ID Residential 136 Bill Impact Workpaper and made the Amendment to the Application of Rocky Mountain Power Page 2 Company aware of the issue on July 14,2025.On July 16,2025,the Company provided a corrected ID Residential 136 Bill Impact Workpaper, with an adjustment, identified as the "Hourly Profile Adjustment",as a result of the issues identified by Staff. On July 23,2025 the Company provided its Pt Supplemental Response to PR 11 which included the corrected ID Residential 136 Bill Impact Workpaper along with an explanation of the changes. The Company's response to PR 11 and also its I't Supplemental Response to PR 11 are attached to this Amendment as Attachment No. 1. II. ADJUSTMENTS A. Summary of Adjustments 4. This Amendment includes two adjustments: a"Season Adjustment"and an"Hourly Profile Adjustment", both of which were identified through the discovery process in this case. With these corrections, the average proposed export credit rate remains 4.2 cents/kWh. However, the proposed summer on-peak rate decreased from 16.24 cents/kWh to 14.66 cents/kWh, the winter off-peak rate decreased from 1.49 cents/kWh to 1.22 cents/kWh, and the winter on-peak rate increased from 4.70 cents/kWh to 5.5 cents/kWh. The net impact to the average customer bill is a decrease of$2 per month as a result of these corrections. The average increase for customer generators decreased from$37 to approximately $35 per month, or from a 72% increase to a 69% average increase compared to the current export rate. B. Season Adjustment 5. As explained in PR 11, in the Company's Application, October was erroneously included as a winter month in the determination of the energy component of the export credit rate (ECR) calculation. In addition, while October was correctly included as summer month on tab "Capacity Contribution", the export credit volumes for the various capacity components were using the erroneous seasonal energy totals from tab "Energy+Int+Losses". As a result of the Amendment to the Application of Rocky Mountain Power Page 3 correction,the summer energy volume increases,while the winter energy volume decreases.While this does not impact the estimated annual value, the change in volumes impacts the rates in the different seasons and on-peak/off-peak periods. Shifting October to be a summer month increases the volume in the summer, and the capacity rate falls as the total capacity value is spread over the larger volume.1 The impact of this change is shown in the last row of Table 2 below. The Company has included an updated Proposed Revised Schedule 136 as Attachment No. 2 to this Amendment. Table 2: Amended Export Credit Summary Summer Summer Winter Winter Export Profile Annual On-Peak Off-Peak On-Peak Off-Peak Volume (kWh per kW) 949 136 387 1 18 1 409 Capacity Contribution (%) 10.97% 8.69% 1.97% 0.03% 0.28% Value by Element(cents/kWh) Energy 2.415 4.024 3.149 1.750 1.213 - Integration (0.385) (0.641) (0.502) (0.279) (0.193) +Avoided Line Losses 0.184 0.306 0.239 0.133 0.092 Generation Capacity 1.488 8.212 0.655 0.240 0.089 Transmission Capacity Deferral 0.069 0.381 0.030 0.011 0.004 Transmission System Cost 0.297 1.490 0.020 3.716 0.013 Distribution Capacity Deferral 0.162 0.893 0.071 0.026 0.010 Total (as Amended) 1 4.230 14,6667 3.664 5.597 1.228 (i)Annual values for information only and reflect seasonal weighting from the historical period.

Included with this Amendment are the following three adjustments (together called the "Hourly Profile Adjustment") to the workpaper titled"ID Residential 136 Bill Impact": For details on the correction,please refer to Attachment IPUC 11.The only modification to the calculations is in cell Q12 of tab "Energy+Int+Losses". Comparisons to the values from the original filing are provided on the bottom of that tab and on new tabs labeled "DELTA" and "Summary As Filed". Note: the formatting error identified in the Company's response to IPUC Data Request 12 is also corrected in this attachment and has no impact on the results. Amendment to the Application of Rocky Mountain Power Page 4 • Tab "ID136 Hourly-Export" was changed to present the hourly export profile in Mountain Prevailing Time (MPT). This change involved shifting the original Pacific Prevailing Time (PPT) export profile by one hour. For example, what was "Hour 7" in PPT is "Hour 8" in MPT. • The "Hour" column on tab "ID136 Hourly-Export" was changed to reflect hour beginning(0 through 23). The original version showed hour ending(1 through 24). This change aligns the presentation of hours for the export profile with the delivery profile. This change has no impact on the profile; it only changes how hours are presented. • The time-of-day periods on tab "ID136 Hour-Export" and tab "ID136 Hourly- Delivery"were corrected. The time-of-day periods in the original work paper were misaligned with the actual time-of-day periods by one hour. 7. As a result of this Hourly Profile Adjustment, and the time shift to the export profile, there is an approximate $4 reduction to the average monthly bill impact.' In addition,the Company also calculated the bill impacts for Season Adjustment which resulted in an approximate monthly bill impact increase of$23,resulting in an overall net decrease of$2 from the original bill impact calculation. This net impact of the two adjustments is shown below in Table 3. 2 See tab "Schl36-AVG Change" of work paper"TOD Edits—ID Residential 136 Bill Impact Workpaper—7-16- 2025.xlsx". s See tab"Schl36-AVG Change"of work paper"TOD&Season Edits—ID Residential 136 Bill Impact Workpaper —7-16-2025.xlsx".

REQUEST FOR RELIEF 8. WHEREFORE, Rocky Mountain Power respectfully requests that the Commission approve the Company's proposed changes, as amended herein, to its on-site self-generation Schedule 136 tariff in accordance with Order No. 36286 and approve the Company's proposed: (1) export credit rate for customers on Schedule 136 beginning October 1, 2025, (2) an increased cap for non-residential customers to 2,000 kW, (3) annual updates to the export credit rate, and(4) updated Schedule 136 tariff incorporating the changes reflected in the Application and this Amendment. Amendment to the Application of Rocky Mountain Power Page 6 DATED this 30th day of July, 2025.

In the worksheet titled "Energy+Int+Losses," October was included as a winter month in the Company's calculation of the energy value of its export credit rate ("ECR"). Considering that the Company proposes crediting customer exports during October at summer ECR rates, please explain why October was included as a winter month for the energy component of the ECR calculation. Response to IPUC Data Request 11 October was erroneously included as a winter month in the determination of the energy component of the export credit rate (ECR) calculation. In addition, while October was correctly included as summer month on tab "Capacity Contribution", the export credit volumes for the various capacity components were using the erroneous seasonal energy totals from tab "Energy+Int+Losses". As a result of the correction, the summer energy volume increases, while the winter energy volume decreases. While this does not impact the estimated annual value, the change in volumes impacts the rates in the different seasons and on-peak/off-peak periods. Shifting October to be a summer month increases the volume in the summer, and the capacity rate falls as the total capacity value is spread over the larger volume. For details on the correction,please refer to Attachment IPUC 11. The only modification to the calculations is in cell Q12 of tab "Energy+Int+Losses". Comparisons to the values from the original filing are provided on the bottom of that tab and on new tabs labeled"DELTA" and"Summary As Filed".Note: the formatting error identified in the Company's response to IPUC Data Request 12 is also corrected in this attachment and has no impact on the results.

Tab "ID136 Hourly-Export"was changed to present the hourly export profile in Mountain Prevailing Time (MPT). This change involved shifting the original Pacific Prevailing Time (PPT) export profile by one hour. For example, what was "Hour 7" in PPT is "Hour 8" in MPT. 2. The "Hour" column on tab "ID136 Hourly-Export"was changed to reflect hour beginning (0 through 23). The original version showed hour ending (1 through 24). This change aligns the presentation of hours for the export profile with the delivery profile. This change has no impact on the profile; it only changes how hours are presented. 3. The time-of-day periods on tab "ID136 Hour-Export" and tab "ID136 Hourly- Delivery"were corrected. The time-of-day periods in the original work paper were misaligned with the actual time-of-day periods by one hour. As a result of the export profile time shift and the time-of-day period correction overviewed above, there is an approximate $4 reduction to the average monthly bill impact as shown on tab "Sch136-AVG Change" of work paper"TOD Edits— ID Residential 136 Bill Impact Workpaper—7-16-2025.xlsx". In addition, the Company also calculated the bill impacts for the adjustments included in its response to IPUC Data Request 11 on top of the time-of-day edits described above. As shown on tab "Sch136-AVG Change" of work paper"TOD & Season Edits—ID Residential 136 Bill Impact Workpaper—7-16-2025.xlsx" there is an approximate monthly bill impact increase of$2 due to this change, resulting in an overall net decrease of$2 from the original bill impact calculation.
