IPC-E-24-42 APPROVAL OF A POWER PURCHASE ) AGREEMENT WITH BLACKS CREEK ) IDAHO POWER COMPANY'S ENERGY CENTER, LLC. ) COMPLIANCE FILING Idaho Power Company ("Idaho Power" or "Company"), pursuant to Idaho Public Utilities Commission ("Commission") Order No. 36572,' hereby respectfully submits the following compliance filing which contains the structure for calculating Brisbie LLC's ("Brisbie") Renewable Capacity Credit ("RCC") under the Brisbie Special Contract ("Brisbie ESA") related to the Power Purchase Agreement ("PPA") between Idaho Power and Blacks Creek Energy Center, LLC ("Blacks Creek"). I. INTRODUCTION In its final order approving the Blacks Creek PPA the Commission directed the Company to work with Staff on the structure for calculating Brisbie's RCC under the Order No. 36572, p. 3. IDAHO POWER COMPANY'S COMPLIANCE FILING - 1 Special Contract and directed the Company to submit a compliance filing with the proposed RCC and associated updates to Schedule 33 within 60 days of the order.2 As more fully described herein, in this compliance filing, Idaho Power presents the Commission with an updated proposed RCC payment structure, which resulted from discussions with Commission Staff("Staff"). More specifically, following the Commission's issuance of Order No. 36572, Idaho Power met with Staff to discuss the following Staff recommendations3 related to the quantification of Brisbie's RCC4: o The Company update the Effective Load Carrying Capacity ("ELCC") by using the most recent load and contracted resource data as of the contract execution date of October 11, 2024 ("Recommendation 2"); o The Company include additional load and resource adjustments to reflect near- term trends in the Final Study when informing the monthly distribution of the annual payment ("Recommendation 3"); o The Company create "seasons" based on the 2028 Loss of Load Probability ("LOLP") profiles determined in the Final Study ("Recommendation 4"); o The Company identify high-risk hours based on the 2028 LOLP profiles determined in the Final Study, with no expansion of risk-hours ("Recommendation 5"); and o The Company establish the relationship between Performance Ratio and ELCC based on the Final Study ("Recommendation 6"). Additionally, use increments of 2 Id., page 3. 3 Staff Comments, page 2 (February 27, 2025). 4 Note, Staff's Recommendation 1 ("the parties modify the definition of Market Price Index and how it is determined to avoid potential impacts of Washington's Climate Commitment Act ("CCA") on Idaho ratepayers," Staff Comments, page 1 (February 27, 2025))was previously addressed and resolved through Order No. 36572. IDAHO POWER COMPANY'S COMPLIANCE FILING -2 0.05 of Performance Ratio to create data points ("Recommendation 6a"); and use a method of the best-fit linear equation with constraints of 100% of the original ELCC at Performance Ratio of 1.0 ("Recommendation 6b"). Following two meetings (May 19, 2025, and May 28, 2025), Idaho Power and Staff were able to resolve Staff's concerns either through clarification of Idaho Power's proposed method or by incorporating improvements suggested by Staff. II. PROPOSED RENEWABLE CAPACITY CREDIT PAYMENT Included as Attachment 1 is a detailed description of the methodology for Company's proposed RCC and the performance mechanism for monthly payments. The proposed RCC follows the same general methodology approved by the Commission in Order Nos. 35735,5 35777,E 35958,' and 36270,$ while incorporating certain adjustments resulting from recent discussions with Staff necessary to ensure the payment for capacity of the renewable project is commensurate with the benefits provided to the system. The maximum value Brisbie is eligible to be paid for capacity delivered by the Blacks Creek project is capped at $8,172,640. The Company addresses each of Staff's recommendations and the resolution of each issue in the comments that follow. 5 In the Matter of Idaho Power Company's Application for Approval of a Replacement Special Contract with Micron Technology, Inc., and a Power Purchase Agreement with Black Mesa Energy, LLC, Case No. IPC-E-22-06, order issued April 12, 2023. 6 In the Matter of Idaho Power Company's Application for Approval of a Special Contract and Tariff Schedule 33 to Provide Electric Service to Brisbie, LLC's Data Center Facility, Case No. IPC-E-21-42, May 11, 2023. Id., order issued October 12, 2023. 8 In the Matter of Idaho Power Company's Application for Approval of a Power Purchase Agreement with PVS 2, LLC, Case No. IPC-E-24-01, July 26, 2024. IDAHO POWER COMPANY'S COMPLIANCE FILING - 3 A. Recommendation 2 — Update to ELCC Staff recommended the Company update the ELCC by using the most recent load and contracted resource data as of the contract execution date of October 11 , 2024. As noted by Staff in comments, the Company had inadvertently included a 50 megawatts storage facility in the quantification of the ELCC that was not yet under contract by the Company, which is inconsistent with the Commission approved methodology and the Company's intent. Accordingly, the Company has updated the ELCC to only include resources that were under contract at the time the Blacks Creek PPA was executed, which results in an ELCC of 17.50 percent, rather than the 18.44 percent included with the Company's original filing. B. Recommendation 3 — Load & Resource ("L&R") Adjustments Staff recommended the Company include additional L&R adjustments to reflect near-term trends when informing the monthly distribution of the annual payment. In its initial filing, the Company had included the expected L&R adjustments known at the time of that filing. After discussions with Staff, the Company adjusted the 2028 monthly Loss of Load Expectation ("LOLE")weighted averages to consider most-recently available data (including an updated load forecast and generation projects that were contracted after Blacks Creek) which better reflects the expected LOLE distribution of future years. These modifications are reflected in Table 2 of Attachment 1. C. Recommendation 4 — Adjustment to Seasons Based on LOLP Staff recommended the Company create "seasons" based on the 2028 LOLP profiles. In its initial filing, the Company had relied on the methodology developed in Case No. IPC-E-22-06 when establishing the RCC of Clean Energy Your Way ("CEYW") IDAHO POWER COMPANY'S COMPLIANCE FILING -4 projects to group the twelve calendar months into three different periods. After discussions with Staff, the Company made an adjustment to apply the seasons of highest risk methodology from the 2023 Integrated Resource Plan ("IRP") to the 2028 L&R year to group the twelve months of the calendar year into three different periods given their LOLP profiles. These modifications are reflected in Table 3 of Attachment 1. D. Recommendation 5 — Performance Metric, High-Risk Hours Staff recommended the Company identify high-risk hours based on the 2028 LOLP profiles, with no expansion of risk-hours. After discussions with Staff, the Company and Staff aligned on applying the most recently acknowledged IRP hours of highest risk methodology to the project online year. More specifically, Idaho Power's proposed high- risk hours for the Blacks Creek project performance metric rely on the same thresholds from the 2023 IRP but are applied to the 2028 L&R year. The identified summer risk hours using the 2023 IRP methodology applied to the 2028 L&R year are 5pm through 12am. In recognition that the hours of highest risk analysis do not capture 100 percent of risk hours, the 4pm through 5pm hour is included to capture expanded risk hours when solar generation is available, which is done to reduce the solar generation measurement variability. The identified winter risk hours using the 2023 IRP methodology applied to the 2028 L&R year are 6am through 3pm and 5pm through 10pm. E. Recommendations 6, 6a, and 6b — Performance Ratio Staff recommended: (1) the Company establish the relationship between Performance Ratio and ELCC, (2) use increments of 0.05 of Performance Ratio to create data points, and (3) use a method of the best-fit linear equation with constraints of 100% of the original ELCC at Performance Ratio of 1.0. Through discussions with Staff, the IDAHO POWER COMPANY'S COMPLIANCE FILING - 5 Company and Staff aligned that Idaho Power would rely on its filed method but include additional data points. That is, the ELCC will be based on the execution date of the Blacks Creek PPA and the data points would be created based on the 0.05 increments suggested by Staff, essentially ensuring the data points will reflect what we knew at the time of contract execution. For the interpolation method applied to the Performance Ratio and ELCC relationship, the Company and Staff also aligned on continuing to utilize the initially filed method of interpolating between the two closest data points. III. CONCLUSION Idaho Power is appreciative of Staff's collaboration in working through the issues identified in Staff's comments. The proposed RCC and performance structure presented in Attachment 1 represents resolution of Staff's identified concerns. Idaho Power believes the proposed RCC and related performance mechanism not only meets the Commission's prior orders, but includes minor adjustments necessary to ensure the unique impacts of each renewable resource is captured, including those added in the same year as other CEYW resources. The ability to incentivize performance to meet today's system capacity needs, while ensuring the resource performs as expected in the future, provides recognition of Idaho Power's reliance on that resource's capacity contribution. To assist Staff in its review, Idaho Power has also provided a draft Schedule 33 as Attachment 2, which reflects the adjustments more fully described herein and throughout Attachment 1. Idaho Power respectfully requests the Commission issue an order (1) approving the proposed RCC, and (2) directing Idaho Power to file conforming tariff sheets.

IPC-E-24-42 IDAHO POWER COMPANY ATTACHMENT 1 Case No. IPC-E-24-42 - Proposed Brisbie, LLC Renewable Capacity Credit Payment Structure for Blacks Creek The Blacks Creek Power Purchase Agreement ("PPA") was executed on October 11, 2024, and the capacity contribution calculated at the time of contract execution was 17.50%. The annual payment is determined by multiplying the average capacity contribution by the avoided cost of capacity. The avoided cost of capacity is the levelized fixed cost associated with the least-cost dispatchable resource from the Company's most recently acknowledged Integrated Resource Plan ("IRP") at the time of PPA execution. In the case of Blacks Creek, the 2023 IRP was the most recently acknowledged IRP at the time of PPA execution. For the 2023 IRP the identified resource was a simple-cycle combustion turbine ("SCCT") with a levelized capacity cost of$145.94 per kW per year. Determine Annual Payment The annual payment is calculated by multiplying the capacity contribution by the nameplate of the selected project by the avoided cost of capacity: Annual Payment = Capacity Contribution* Project Nameplate *Avoided Cost of Capacity Applying the annual payment calculation to the Blacks Creek project, the resulting value is determined to be $8,172,640 per year: Annual Payment = 17.50% * 320,000 kW * $145.94 y � � � � kW • yr $8,172,640/yr Determine Months of Capacity Need The annual payment will be calculated at the time of contract execution and distributed proportionally over the months that capacity is expected to be needed. To determine the months of capacity need, the Loss of Load Expectation ("LOLE") per month of the different historical years would be used to calculate an average LOLE for each month. If a significant resource stack change is expected in the near future, an adjusted case would be used to guide the monthly weighted average calculations. Because the Blacks Creek Energy Center project is contracted to come online in December 2027, a 2028 Load & Resource ("L&R") year was used to determine the months of capacity need. The average monthly LOLE values for the 2028 L&R year are listed in Table 1 . Table 1. 2028 L&R Average Monthly LOLE Month Average LOLE January 0.001856 February 0.000176 March 0.000006 April 0.000000 May 0.000000 June 0.013046 July 0.025399 August 0.003066 September 0.000297 October 0.000301 November 0.037979 December 0.017552 In review of the projected near-term load and resource buildout, Idaho Power adjusted the 2028 monthly LOLE weighted averages to better reflect the expected LOLE distribution of future years and to consider most-recently available data (including an updated load forecast and generation projects that were contracted after Blacks Creek). Using the results from the adjusted 2028 L&R year analysis, the monthly LOLE weighted averages are listed in Table 2. Table 2. 2028 Monthly LOLE Weighted Average Month Weighted Average January 3.33% February 0.19% March 0.02% April - May - June 19.95% July 50.32% August 8.04% September 0.30% October 3.65% November 12.13% December 2.06% The Company applied the seasons of highest risk methodology from the 2023 IRP to the 2028 L&R year in order to group the twelve months of the calendar year into three different periods given their Loss of Load Probability ("LOLP") profiles, as described in the list below: • Summer: June, July, August, and September • Winter: January, February, October, November, and December • Off-Season: March Note that April and May remain at 0% LOLP. A weighted average per period is calculated by adding the percentages of each month within the corresponding period together, as shown in Table 3. Table 3. 2028 LOLE Weighted Average per Period Summer Winter Off-Season June 19.95% January 3.33% March 0.02% July 50.32% February 0.19% August 8.04% October 3.65% September 0.30% November 12.13% December 2.06% Summer Total --79% Winter Total -21% Off-Season Total _0% For the winter and off-season periods, the total is spread out relatively equally over the months; this means the approximate 21% for the winter total would be divided by the 5 months for a resulting 4.2% in each month, and because the off-season total rounds to an approximate 0%, the month of March will receive no payment. For the summer period, the hours of need typically span from the last 2 weeks of June through the first 2 weeks of September (totaling 12 weeks), meaning there are 2 weeks in June, 4 weeks in July, 4 weeks in August, and 2 weeks in September that should be considered in the monthly payment distribution. Because the summer total is set to equal the approximate 79%, the high LOLP hours weekly weighting can be used to distribute the summer period risk: • June - 79% * 2 weeks = 13.17% 12 weeks • July - 79% * 4 weeks 1 = 26.33% (12 weeks • August - 79% * (12 4 weeks weeks) = 26.33% • September - 79% * (12 weeks) = 13.17% The final weights by month are shown in Table 4. Table 4. 2028 Seasonal Monthly LOLE Weighted Average Month Weighted Average January 4.20% February 4.20% March - April May - June 13.17% July 26.33% August 26.33% September 13.17% October 4.20% November 4.20% December 4.20% The monthly payment is calculated by taking the previously calculated annual payment of $8,172,640 per year and multiplying it by the weighted average for each month, as shown in Table 5. Table 5. 2028 Seasonal Monthly Payment Month Weighted Average Monthly Payment January 4.20% $343,251 February 4.20% $343,251 March - - April -May - - June 13.17% $1,076,064 July 26.33% $2,152,129 August 26.33% $2,152,129 September 13.17% $1,076,064 October 4.20% $343,251 November 4.20% $343,251 December 4.20% $343,251 Total 100.00% $8,172,640 Performance Metric The Performance Ratio ("PR") is a metric widely used to track performance of photovoltaic ("PV") systems in the industry.1,2,3 The PR metric can be used to ensure a project is being well maintained and is performing as expected. PR can be defined as the ratio of measured output to the expected output for a given reporting period based on the system nameplate rating. Traditionally, PR is mathematically expressed as kW haC kWoc,sTC PR kW hsun M2 1 kW m2 where IEC 61724-1: 2017 Photovoltaic System Performance 2 Performance of Photovoltaic Systems Recorded by oSPARC, NREL 2020 3 PV System Performance Assessment, Sunspec Alliance, San Jose State University, 2014 kWhAc = Energy Generated by the Plant kWDc,STc = Rated Direct Current Power of the Plant at Standard Test Conditions kWhsun = Plane of Array ("POA") Irradiance The PR metric is most often used by power plant operators to track plant performance. Idaho Power modifies the previously shown equation to consider the contracted nameplate of the plant on the Alternating Current ("AC") side and not on the Direct Current ("DC") side. The contract with Idaho Power is on the AC side and it has the potential to be the limiting factor during operation. The modification results in the following PR equation: kW hac PR = kWNP,Ac * kW hsun One of the interconnection requirements is for the project to provide Idaho Power with weather data via Supervisory Control and Data Acquisition ("SCADA"). One of the variables required is the Plane of Array ("PDX) irradiance (kWhsun)• The energy injected into the system is also measured via SCADA, making the PR calculation relatively straight-forward. Performance Ratio Target The PR metric is directly impacted by the energy output which is proportional to irradiance and inversely proportional to module temperature. The PR equation accounts for irradiation; changes in irradiation will have little effect on the PR. However, changes in temperature are not accounted for in the PR calculation and the PR will decrease as temperature increases. To account for the impact of temperature on the PR calculation, Idaho Power proposes to set a different PR target for the summer months than the non- summer months. The Company proposes to use the PR targets described in Table 7 and graphically displayed in Figure 1. Table 7. PR Targets by Period Period Target January through May PR > 1.0 June through September PR > 0.95 October through December PR > 1.0 Performance Metric Threshold by Month 1 v 0 „ 0.9 r 0 1-- 0.8 m oc 0 U C C C 7 O N a 0.6 0.5 - 2 4 6 8 10 12 Month of the Year Figure 1. PR Targets by Month Hours of Need Capacity is primarily avoided during certain hours of the calendar year. The hours where capacity is most needed are the hours which have high LOLP values. To provide compensation for capacity when it is needed, the PR metric will be calculated based on the 2023 IRP hours of highest risk methodology applied to the 2028 L&R year, which are provided in Table 8. Table 8. 2028 L&R Year High LOLP Hours Period Identified High LOLP Hours for 2028 L&R Year Summer4 4:00 pm - 12:00 am Winter 6:00 am - 3:00 pm & 5:00 pm - 10:00 pm For clarification, the hours presented in Table 8 are Hour Beginning ("HB") for the first interval and Hour Ending for the second interval ("HE"). Using the summer period as an example, 4:00 pm HB represents the hour spanning from 4:00 pm to 5:00 pm while 12:00 am HE represents the hour spanning from 11:00 pm to 12:00 am; this means the identified summer period high LOLP hours begin at 4:00 pm and conclude at 12:00 am. Reduction on Payment To receive the full monthly payment, the project will have to meet the PR threshold in the corresponding high LOLP hours (as set forth in Table 8). If the PR is not met, a reduction in payment will be applied to the project. The reduction will be calculated based on the impact to capacity as measured by the ELCC. The impact on capacity will be determined by reducing the output of the project and calculating its ELCC. For the Blacks Creek Energy Center project, the relationship between output and ELCC reduction was calculated over the range of 0.5 PR to 1.0 PR, as shown in Figure 2. 4 Identified Summer risk hours using the 2023 IRP methodology applied to the 2028 L&R year are 5:00 pm - 12:00 am. In acknowledgement that the hours of highest risk analysis does not capture 100% of risk hours and due to the limited solar PV generation possible in the 5:00 pm to 12:00 am window in certain months of the Summer period, the 4:00 pm - 5:00 pm hour is included to capture risk hours when solar generation is available and reduce the solar generation measurement variability. For LOLP hours outside of solar PV generation hours, the expectation of solar PV generation based on irradiance at the site is zero. Performance Ratio versus ELCC 100% • • • U 90% • w • c • Eb 80% • .L O • 4-- 0 70% • v t • M +- u 60% v a 50% 0.50 0.55 0.60 0.65 0.70 0.75 0.80 0.85 0.90 0.95 1.00 Pv Output Figure 2. Relationship Between PR & ELCC The results shown in Figure 2 will be used to determine the monthly payment reduction if the project did not meet the monthly PR target. If any month where capacity payments are applied do not meet the corresponding target PR, a reduction as presented in Figure 2 would be applied (the reduction is calculated by interpolating between the monthly PR value and the target PR value for that month). As an example of how the PR versus ELCC approach would be implemented, data for a similar project near the Blacks Creek Energy Center site was collected for the 2023 L&R; the PRs were then calculated for the corresponding high LOLP hours of each month with the results shown in Table 9 (bolded values represent calculated PR values that did not meet the targets identified in Table 7).
