FOR APPROVAL ) OF ITS WIDLFIRE MITIGATION PLAN ) APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. FOR APPROVAL OF ITS WILDFIRE MITIGATION PLAN Pursuant to the Idaho Public Utilities Commission's ("Commission") Rule of Procedure 52, and the Commission's order issued in this proceeding on September 29, 2025 (Order No. 36774), Kootenai Electric Cooperative, Inc. ("KEC" or"Applicant") hereby submits its Application for Approval of its Wildfire Mitigation Plan("Application"). Pursuant to the Wildfire Standard of Care Act, KEC respectfully requests that the Commission approve its 2026- 2028 Wildfire Mitigation Plan that is attached hereto as Attachment 1 ("Plan"). Pursuant to the Wildfire Standard of Care Act, KEC respectfully requests that the Commission approve its Plan. Page - 1 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. I. BACKGROUND A. Description of Kootenai Electric Cooperative KEC is an Idaho non-profit, member-owned, electric cooperative. KEC's main office is located in Rathdrum, Idaho. KEC provides electric service to roughly 30,000 meters in Kootenai, Beneway, and Bonner counties in Idaho. See Plan at Figures 1 and 2. KEC also provides electric service to a small number of members in Spokane County, Washington. Id. Additional information about KEC is included in the Need to Know Document' attached hereto as Attachment 2. B. Background on Wildfire Mitigation Filing In the 2025 legislative session, the Idaho Legislature enacted the Wildfire Standard of Care Act. 2025 Idaho Sess. Laws Ch. 249 (S.B. 1183) ("Act"). The Act, among other things, allows electric corporations that are not public utilities to adopt and file wildfire mitigation plans with the Commission. I.C. § 61-1803(2)(b). The Commission is required to approve or reject each wildfire mitigation plan within six(6)months of the date such wildfire mitigation plan is filed with the Commission. I.C. § 61-1804(1). In Order No.36774, the Commission adopted a schedule for filing wildfire mitigation plans. Pursuant to that schedule, KEC is authorized to file its Plan on or after October 1, 2025. II. DESCRIPTION OF WILDFIRE MITIGATION PLAN Each wildfire mitigation plan is to identify a means for mitigating wildfire risk that reflects a reasonable balancing of mitigation costs with the resulting reduction of wildfire risk. I.C. § 61-1803(3). The Act sets forth the elements that are required to be included in each wildfire mitigation plan. Id. In Order No. 36774, the Commission adopted the Idaho Public 1 In Order No.36774,the Commission ordered that each electric municipality and cooperative to file a"Need to Know Document". Page - 2 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. Utilities Commission Wildfire Mitigation Plan Guidelines ("Guidelines") regarding the content of wildfire mitigation plans. As discussed below, KEC's Plan includes the elements required by the Act and complies with the Guidelines.2 A. KEC's Plan Includes A Minimum of a Three-Year Forecast In Order No. 367743, the Commission adopted Staff s proposal that each wildfire mitigation plan represent, at a minimum, a three-year forecast for each version. The Commission found that it is "reasonable to require electric corporations to develop rolling WMPs with a minimum three-year planning horizon." Order No. 36774 at 15. KEC's Plan is based on a three-year planning horizon. Plan at Section 1.1. The body of KEC's Plan and Vegetation Management Plan("VMP")4 contain the general provisions applicable to all time periods covered by the Plan. KEC forecasts its vegetation management, construction work, and system inspections in its three-year rolling Vegetation Management Implementation Plan ("VMIP"), Construction Work Implementation Plan ("CWIP"), and System Inspection Implementation Plan (SIIP). KEC's 2026-2028 VMIP, CWIP and SIIP are attached to, and part of, the Plan as Appendices A-1, B, and C respectively. B. Geographical Risk Assessments The Act requires each wildfire mitigation plan to identify geographical areas where the electric corporation has infrastructure or equipment that the electric corporation considers may be subject to heightened risk of wildfire at the time the wildfire mitigation plan is finalized. I.C. § 61-1803(3)(a). The Guidelines provide that each wildfire mitigation plan is required to include 2 The Guidelines require WMPs to include a section describing how the electric corporation addresses each of the Commission's orders and Staff's recommendations. Guidelines at 8. In addition to the description set forth in this Application,KEC's Plan includes a compliance matrix(Appendix E to the Plan)that describes the sections of KEC's Plan that comply with the requirements and recommendations. 'See Order No. 36774,reconsideration den.,Order No.36849,clarified,Order No. 36882. 'KEC's VMP is Appendix A to KEC's Plan. Page - 3 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. a description of the wildfire risk assessment or model used to guide wildfire mitigation activities. Guidelines at 2. Each wildfire mitigation plan should identify geographic areas with elevated fire risk, considering factors such as vegetation, weather, topography, historical fire occurrence, structure density, and asset location and should provide a map of the identified risk areas within the electric corporation's service territory.' Id. Finally, each wildfire mitigation plan must include an explanation of what determines each level of risk. Id. Section 2 of KEC's Plan identifies the general geographic areas that are served by KEC and identifies the areas that may be subject to heightened risk of wildfire. See I.C. § 61- 1803(3)(a). As described in the Plan, KEC uses a combination of resources and data to determine specific geographical areas that are considered to have a heightened risk of wildfire. Plan at Section 2. These areas are shown on a map included in KEC's Plan as Figure 3. Most of the areas served by KEC are identified as "medium", "high" or"very high"wildfire risk zones and, therefore, are defined by KEC as "Heightened Risk Areas".6 Id. C. Preventive Actions and Programs The Act requires each wildfire mitigation plan to include the preventive actions and programs that the electric corporation will carry out to reduce the risk of wildfire. I.C. § 61- 1803(3)(b). The Guidelines require wildfire mitigation plans to include the following specified preventive actions and programs: (i) situational awareness efforts, (ii) asset inspections, (iii) enhanced vegetation management practices in risk zones, (iv) operational practices during 5 The maps provided in KEC's Plan generally depict the geographical areas that KEC serves. However, in some areas depicted,other utilities also serve customers in the same general geographic area. For example,KEC and Avista both serve customers in and around Kootenai County,Idaho. 6"Heightened Risk Areas"are those areas identified in Section 2 of the Plan that KEC considers may be subject to heightened risk of wildfire at the time this Plan is finalized. See Plan at Section 1.1 (defining"Heightened Risk Areas");I.C. § 61-1803(3)(a). Page - 4 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. heightened wildfire risk days or zones, and(v) community education. Guidelines at 2-3. As discussed below, KEC's Plan includes these preventive action programs. 1. Situational Awareness Efforts The Guidelines provide that situational awareness efforts "may include the use of technology to aid in weather monitoring, fire season outlook, daily, weekly, and monthly weather and fire modeling risk, etc." Guidelines at 3. The Act requires wildfire mitigation plans to include "[m]onitoring of forecasted and current weather data for the purpose of assessing and responding to current and anticipated Ere risk[.] I.C. § 61-1803(3)(f). Similarly, the Guidelines require that wildfire mitigation plans should include a description of how the electric corporation monitors forecasted and current weather conditions for the purpose of assessing and responding to current and anticipated wildfire risk. Guidelines at 5-6. This description must include: • Identification of systems, tools, or external resources used to monitor weather, fire potential, or other situational awareness indicators. • If applicable, a description of how the utility utilizes weather forecasting, fire potential, modeling, or similar tools to inform mitigation activities and operational decisions. • Discussion of how situational awareness capabilities are integrated into daily or seasonal wildfire operations. • Discussion of how the electric utility becomes aware of another electric corporation's de-energization and how that is integrated into operations. Id. Section 4 of KEC's Plan contains its fire season operational guide. As set forth in Section 4.1 of KEC's Plan, KEC uses Tempest to determine the daily fire risk in areas served by KEC. In the Plan, Figure 4 provides an illustrative example of the information provided by Tempest. Based on the information provided by Tempest, KEC's Operations Superintendents review the Daily Situational Awareness Tool (Plan at Figure 5) and its associated mitigation strategies (Plan at Figure 6). Page - 5 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. KEC also monitors the National Fire Danager Rating ("NFDR"). The NFDR is used to guide operational decisions, such as whether circuit breakers will be set for automatic reclose, whether to increase the number of on-call personnel, and whether to pre-position personnel. Plan at Figure 7. The NFDR is also used, in part, to guide decisions regarding whether to initiate a public safety power shutoff("PSPS"). See id. at Sections 4.2-4.3.7. Finally, KEC will, to the extent practical, communicate any anticipated or actual PSPS with any neighboring utility that may be impacted by the PSPS. KEC anticipates that neighboring utilities will similarly share information regarding any anticipated or actual de- energization that will impact KEC. To the extent that KEC obtains information from another utility regarding any de-energization that will impact KEC, KEC will integrate such information in its operational planning. See Plan at Section 5.2 2. Asset Inspections The Act requires the development of standards, procedures, and schedules, subject to timely approval of access to rights-of-way, for"[i]nspection of the electric corporation's assets, infrastructure and facilities within areas that are identified as heightened fire risk areas in the wildfire mitigation plan[.] I.C. § 61-1803(3)(g)(i). The Guidelines further provide that asset inspections "must include the frequency and standards for inspections of each type of electric infrastructure within areas of elevated wildfire risk." Guidelines at 3. As set forth in Section 3.4 of its Plan, KEC performs inspections of its system in accordance with its System Inspection Implementation Plan ("SIIP"). The SIIP is attached to KEC's Plan as Appendix C. KEC also performs certain inspections in accordance with its VMP and VMIP, which are attached to KEC's Plan as Appendices A and A-1, respectively. Page - 6 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. 3. Enhanced Vegetation Management Practices in Risk Zones The Act requires the development of standards, procedures, and schedules for vegetation management within the areas that are identified as heightened risk areas. I.C. § 61-1803(3)(g)(i). Enhanced vegetation management practices in risk zones "may include shorter vegetation management cycles than routine cycles, risk tree programs, etc." Guidelines at 3. KEC's VMP identifies KEC's vegetation management standards and describes the current and planned vegetation management practices used to mitigate wildfire risk. As discussed in the VMP, KEC's standard practice is to clear vegetation within fifteen (15) feet of the centerline of KEC's facilities, except as otherwise required by applicable federal, state, or local laws, regulations, or ordinances ("Applicable Laws"). Plan, Appendix A at 2. Where clearing in accordance with the standard practice is either not permitted or is impractical,pruning will be performed in a manner that is consistent with best management practices as published by the International Society of Arboriculture (ISA) guidelines, including ANSI A300, applicable OSHA requirements, and all Applicable Laws. The VMIP includes measurable targets/goals to be achieved under the Plan. Specifically, the VMIP includes a schedule of those portions of KEC's electrical system (by feeder) where vegetation management is projected to be accomplished in each of the three years covered by the VMIP. See Plan at Appendix A-1. Finally, the VMP includes requirements to identify, and prioritize for removal, hazard trees. Id. at Appendix A at 4. Planners will assess hazard trees, and a crew is specifically assigned to remove hazard trees. Id. at Appendix A-1. As noted above, most of the areas that KEC serves are classified by KEC as Heightened Risk Areas. See id. at Figure 3. Accordingly, all areas in which KEC performs vegetation Page - 7 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. management are generally treated the same for purposes of KEC's VMP.7 KEC will, however, prioritize certain vegetation management, such as hazard tree removal and member tree tickets, in areas with a higher wildfire risk. 4. Operational Practices During Heightened Wildfire Risk Days or Zones The Act requires the development of standards, procedures, and schedules for de- energization of the electric corporation's power lines, if the electric corporation considers it appropriate. I.C. § 61-1803(3)(g)(i). The Guidelines provide that operation practices during heightened wildfire risk days or zones may include restrictions on workforce practices and potential use of proactive de-energization. Guidelines at 3. KEC's operational practices are addressed in Sections 3.4 through 4.3.7 of KEC's Plan. As discussed above, KEC uses the NFDR to guide operational decisions, including whether circuit breakers will be set for automatic reclose, whether to increase the number of on call personnel, and whether to pre-position personnel. Plan at Figure 7. The NFDR is also used, in part, to guide decisions regarding whether to initiate a PSPS. E.g., Plan at Figure 8. KEC's standards and practices with regard to a PSPS are specifically addressed in Sections 4.2-4.3.7 of KEC's Plan. 5. Community Education The Act requires wildfire mitigation plans to address (i) community outreach and public awareness efforts that the electric corporation will use before, during, and after wildfire season to 7 The Guidelines anticipate that vegetation management standards,procedures,and schedules for Heightened Risk Areas may be the same as for routine vegetation management. Guidelines at 8(requiring an explanation of how vegetation management standards,etc."are different or the same as routine vegetation management."). As discussed herein,because the vast majority of the areas that KEC serves are Heightened Risk Areas,KEC's vegetation management standards,procedures,and schedules for Heightened Risk Areas are the same as for routine vegetation management. Page - 8 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. identify and inform the public of relevant wildfire risks and notify the public of wildfire-related outages, I.C. § 61-1803(3)(c), and(ii) outreach efforts to coordinate with federal, state, tribal, and local officials and agencies on wildfire preparedness and emergency response plans, I.C. § 61-1803(3)(g)(d). The Guidelines provide that community education may include public service announcements to create awareness and provide education of wildfire risks and providing preventative measures. KEC's community outreach and public awareness efforts as well as its efforts to coordinate with federal, state, tribal, and local agencies are addressed in Section 5 of its Plan. Notably, KEC's Plan includes an annual coordination meeting with federal, state, tribal, and local officials and agencies to coordinate on wildfire preparedness and emergency response plans. This annual coordination meeting is to be held prior to May 1 of each calendar year to ensure proper coordination with such officials and agencies prior to the start of the wildfire season. See I.C. § 61-1803(3)(d). KEC's Plan also provides for communications with applicable agencies when the NFDRS rises to "High" or above and during Red Flag Warning Days (Plan at Section 5.1.2) and leading up to and during a PSPS (Plan at Section 5.1.3). KEC will communicate with the Idaho Office of Emergency Management("OEM") regarding any potential or actual PSPS. OEM in turn will notify other agencies and officials. Plan at Section 5.1.3. KEC will also share information with its members, the public, the media, and other stakeholders. Id. at Section 5.2. Such information will be shared via KEC's monthly newsletter, KEC's website, social media, email, and/or news releases. Id. at Section 5.3. Page - 9 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. D. Additional Information Order No. 36774 requires each electric corporation to provide a cost-benefit analysis that justifies its expenditures for wildfire risk mitigation. Order No. 36774 at 17 The Guidelines further require a breakdown of each program category's forecasted costs. Guidelines at 8. As discussed in KEC's comments submitted in the generic proceeding: . . . wildfire risk mitigation is just one of several factors that may be considered with regard to any particular expenditure. In most instances, it is difficult, and probably impossible, to distinguish between the costs attributable to wildfire risk mitigation associated with certain activities—such as undergrounding lines, installing steel poles, replacing outdated equipment, and even vegetation management—and costs of normal operations or costs to improve service or for reliability. KEC Comments at 7. In response to these concerns, Staff stated in its reply comments that it"understands that wildfire mitigation is only one part of an electric corporation's operations, and many projects will cross the line from pure wildfire mitigation into other purposes." Staff Reply Comments at 8. Nevertheless, Staff stated that it does not believe allocation of costs is needed; rather, electric corporations should"include the full costs of the project within the WMP and then mention that there were other criteria beyond just wildfire mitigation for each project with an explanation of those criteria." Id. To the extent the Commission requires a breakdown of costs by category, KEC's VMIP, CWIP, and SIIP include the projected estimated costs of vegetation management, construction work, and system inspections that KEC expects to perform during the next three calendar years. The work to be performed by KEC pursuant to its Plan(including its VMIP, CWIP, SIIP) is performed to, among other things, mitigate wildfire risk. Work performed pursuant to KEC's VMIP and CWIP also serves to update KEC's electrical system, provide service to members, and enhance reliability. KEC's board has reviewed the costs associated with KEC's Plan and the Page - 10 APPLICATION OF KOOTENAI ELECTRIC COOPERATIVE, INC. rationale for the work and has accepted KEC's Plan. See Resolution 10-25 ("Resolution") attached to KEC's Plan as Appendix D. The Act requires the Commission, in reviewing each wildfire mitigation plan, to (i) ensure that such plan meets the minimum requirements of the Act, including that the plan includes financially prudent and reasonably practicable methods of line design for new, planned, and existing lines to mitigate fire risk and(ii)to consider certain factors, including the feasibility of the plan and the cost of its implementation. I.C. § 64-1804. The Act also requires consideration of feasibility of the plan and the costs of its implementation; the Act does not require the Commission to make an independent determination regarding feasibility and costs. See id. As set forth in the Resolution, KEC's board of directors has reviewed the Plan and its costs of implementation and has determined that the Plan (i) includes financially prudent and reasonably practicable methods of line design for new,planned, and existing lines to mitigate fire risk; (ii) is feasible; and(iii) reflects a reasonable balancing of mitigation costs with the resulting reduction of wildfire risk. Accordingly, KEC's board of directors has accepted KEC's Plan. The Resolution support's KEC's cost rationale and justification of need regarding costs associated with KEC's Plan.8 III. Communications All communications regarding this Application should be addressed to: s KEC is not a public utility. Determinations regarding financial prudency,practicability,and feasibility of KEC's operations,including costs of those operations, are within the exclusive purview of KEC's board of directors. KEC respectfully submits that,in evaluating KEC's Plan,the Commission should consider KEC's governing board's assertion in the Resolution that it has reviewed the Plan and determined that it(i)includes financially prudent and reasonably practicable methods of line design for new,planned,and existing lines to mitigate fire risk;(ii)is feasible;and(iii)reflects a reasonable balancing of mitigation costs with the resulting reduction of wildfire risk,to satisfy the requirements of the Act regarding the prudency,practicality,and feasibility of costs of KEC's Plan.

Introduction Kootenai Electric Cooperative, Inc. (KEC), founded in 1938, is the largest of ten not-for-profit, member- owned cooperative utilities in Idaho in terms of load and total customers served. With its main office in Rathdrum, Idaho, KEC provides electric utility service to its members primarily in Kootenai County. It also serves portions of Bonner and Benewah counties in Idaho, and Spokane County in Washington. KEC's service territory is quasi-urban in nature with over half of its power lines being underground. While the largest cooperative in the state in terms of load and customers served, other cooperatives are larger in terms of miles of lines. KEC's mission is to provide its members with exceptional service and dependable power at competitive rates. 1.1 Purpose of the Wildfire Mitigation Plan The primary objective of KEC's Wildfire Mitigation Plan ("Plan") is to provide direction to staff with regard to (i)the design, inspection, operation and maintenance of KEC's electrical system to mitigate wildfire risk; (ii) coordination with federal, state, tribal, and local officials and agencies on wildfire preparedness and emergency response plans; and (iii) outreach and public awareness efforts to be used before, during, and after wildfire season to identify and inform the public of relevant wildfire risks and to notify the public of wildfire-related outages. KEC's Plan utilizes a three-year planning horizon. Specifically, KEC's Plan includes a rolling three-year Vegetation Management Implementation Plan, Construction Work Implementation Plan, and System Inspection Implementation Plan that, respectively, forecast the vegetation management, construction, and system inspection work for the next three calendar years. In March 2025, the State of Idaho enacted the Wildfire Standard of Care Act, Idaho Code §§ 61-1801 to 61-1808 (Act). Among other things,the Act affords electric cooperatives, like KEC, the ability to adopt and file a wildfire mitigation plan with the Idaho Public Utilities Commission ("Commission")for review and approval. KEC's Plan is designed to comply with the requirements of the Act. Effective Date: Upon acceptance by the KEC board, KEC will take steps to implement this Plan and this Plan shall remain in effect until such time as this Plan is superseded by a Commission-approved wildfire mitigation plan or is superseded or rescinded by board action. 1.2 Definitions Below are definitions of some frequently used terms. Act:The Wildfire Standard of Care Act, Idaho Code §§ 61-1801 to 61-1808, as such Act may be amended or superseded. Commission:The Idaho Public Utilities Commission. Construction Work Implementation Plan (CWIP): KEC's three-year rolling Construction Work Implementation Plan referred to in Section 3.1 and attached as Appendix B to this Plan. Construction Work Plan: KEC's Construction Work Plan referred to in Section 3.1 of this Plan. Energy Release Component(ERC):The Energy Release Component is a number related to the available energy(BTU) per unit area (square foot) within the flaming front at the head of a fire. Daily variations in ERC are due to changes in moisture content of the various fuels present, both live and dead, or Fire Potential Index model to assess local wildfire risks. KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 2 DECEMBER 31,2025 Heightened Risk Areas: Heightened Risk Areas are those areas identified in Section 2 of this Plan that KEC considers may be subject to heightened risk of wildfire at the time this Plan is finalized and may change due to changes in circumstances, including changes in weather.

First, as shown in Figure 3, KEC utilizes data from Wildfire Risk to Communities.2 This data rates the areas from very low to very high, based on techniques developed to create various simulations factoring in weather,topography, ignitions and vegetation. This data is then overlayed with proprietary vegetation management software that produces further insight into how those areas overlap within the KEC service area and infrastructure.This allows KEC to better understand how the identified wildfire risk zones align with vegetation encroachments and hazard trees and develop vegetation management goals to prioritize heightened risk zones.

Preventive Actions and Programs to Reduce Risk of Wildfire 3.1 Grid Modernization KEC has developed its 2025-2029 Construction Work Plan Wildfire risk zones 0 (Construction Work Plan)to modernize its electric system. The veryniy Construction Work Plan includes reasonably practical methods � for new, planned, and existing lines to, among other things, Low M Very low mitigate fire risk. The Construction Work Plan, is a five-year plan that includes projects to ensure that power system has the capacity to meet the growing demands of the members served, and to modernize KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 6 DECEMBER 31,2025 the grid by replacing end of life equipment, enhancing reliability, and mitigating fire risk. Projects included in the Construction Work Plan include: • Replacing end of life oil circuit reclosers (OCR) and other strategically located reclosers with solid dielectric,vacuum interrupted reclosers equipped with solid-state controls and advanced protection schemes; • Installing new solid dielectric,vacuum interrupted reclosers on KEC feeders originating from non- KEC owned substations to provide advanced protection schemes; • Installing, in strategic locations, solid dielectric insulated pad-mounted switchgear equipped with operators and solid-state controls connected to the SCADA system to provide remote indication, monitoring, and control; and • Installing new protective feeder relays equipped with Arc Sense Technology(AST) in KEC owned substations for high-impedance fault detection on distribution feeders. The Construction Work Plan also includes finalizing the integration of a new SCADA system with an existing Geographic Information System (GIS).This integration will set up the framework required to deploy SCADA to feeder-level devices and perform Advanced Distribution Management System (ADMS) functions. The additional ADMS functions include, among other things,the ability to remotely control feeder level reclosers outside of substations, remotely adjust protection settings, and automatically detect and isolate sections of the power system through Fault Location Isolation and System Restoration (FLISR). To implement its Construction Work Plan, each calendar year, KEC develops a Construction Work Implementation Plan ("CWIP"). The CWIP provides a forecast of the work in the Construction Work Plan that KEC intends to perform in each of the next three calendar years. KEC's CWIP is incorporated into this Plan and is attached hereto as Appendix B. 3.2 Methods of Line Design for New, Planned, and Existing Lines to Mitigate Fire Risk In addition to modernization discussed in Section 3.1 above,the Construction Work Plan includes steps to harden KEC's electrical system with upgrades and design changes.These designs stem from engineering experience and the adoption of emerging technologies. The Construction Work Plan includes: • The use of ductile iron poles for fire-resiliency construction of overhead distribution lines; • The undergrounding of overhead distribution lines to improve reliability and eliminate the impact of wind and tree related outages, which provides effective wildfire mitigation strategies; and • The replacement of traditional expulsion fuses with current limiting fuses,when possible, in strategic high-risk wildfire zones to reduce the energy and potential ignition source for wildfires. 3.3 Vegetation Management KEC has adopted a Vegetation Management Plan (VMP)to identify and control or eliminate vegetation that threatens the integrity, reliability, or safety of the electrical facilities that are part of KEC's electrical system. The VMP calls for the assessment of KEC's service territory every two (2)years and provides wildfire risk analysis, hazard tree identification,tree segmentation, height and health analysis, 3D vegetation risk scoring, and recommended work. Pursuant to the VMP,vegetation management is performed in accordance with applicable federal, state, or local laws, regulations, or ordinances. KEC's VMP is incorporated herein and is attached hereto as Appendix A. KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 7 DECEMBER 31,2025 To implement its VMP, each year KEC prepares a Vegetation Management Implementation Plan (VMIP). The VMIP that is developed each year is a three-year rolling plan. That is,the VMIP that is developed in each calendar year sets out the strategy, resources, and schedule for vegetation management to be performed in the next calendar year as well as a projected schedule for the following two calendar years. Each VMIP establishes the specific sections of KEC's electrical system (identified by specific feeders) that are targeted for vegetation management in each calendar year. The VMIP is developed using information available to KEC at the time the Implementation Plan is prepared. KEC will monitor conditions and needs and may modify the implementation of its VMP in response to changes in circumstances to the extent KEC deems necessary to provide for the safe, efficient, and reliable distribution of electric power to KEC's members. KEC's 2026-2028 VMIP is attached hereto as Appendix A-1. 3.4 Development of Standards, Procedures,and Schedules for Inspection of KEC's Assets, Infrastructure, and Facilities Within Heightened Fire Risk Areas In addition to the assessments performed in accordance with KEC's VMP (discussed in Section 3.3 above), KEC also performs inspections of its system in accordance with its System Inspection Implementation Plan,which is attached hereto as Appendix C. All inspection data is electronically recorded and tied to specific map locations. Recording this data provides a centralized and accessible record of asset condition over time.This electronic system supports maintenance and tracking of repairs. KEC follows a time-based inspection cycle for system assets: • Overhead and Underground Line Assets: Inspected on a 12-year cycle. • Switchgear: Inspected on a 1-to 4-year cycle depending on asset type and location. • Substations: Inspected monthly. All defects identified during inspections are documented and routed to Operations for timely repair or replacement. 4. Fire Season Operational Guide 4.1 Daily Situational Awareness During periods when the National Fire Danager Rating is elevated to a level of High or greater(as defined in Figure 7), daily morning briefings will be held (on normally scheduled workdays) by the Operations Superintendents with the line crews and Operations staff to review the daily fire risk in the areas served by KEC as indicated by the Tempest system. An example of the information provided by the Tempest system is seen below in Figure 4.

Figure 8 Fire Season PSPS Decision Making Process/Operational Table9 4.3.1 Risk Monitoring and Forecasting During periods where conditions are at Level 0 or Level 1 as set forth in Figure 8, Operations will monitor: • Weather forecasts and information, including: o National Weather Service Regional Weather at: https://www.weather.gov/otx/firedashboard. o Tempest One weather stations with wind alert configuration via email and text. o Tempest One Daily Situational Awareness Tool to determine best operational practices. o Windy.com with Mapping Overlay to determine time and duration of wind events. 'Fire weather refers to weather conditions that create a higher risk of fire generally due to higher temperatures, lower relative humidity,and/or high winds. 'High wind means generally sustained winds over 20 mph and/or wind gusts exceeding 30 mph. Low humidity is generally when the relative humidity is below 20%,which creates drier fuels and increased fire potential. 8 Weather events are extreme weather conditions, such as high temperature and low humidity combined with high winds, create or exacerbate the potential for wildfires. 'This Figure 8 is intended to be used solely as a tool to aid the decision-making process to determine whether and when to activate a PSPS. Decisions whether and when to activate a PSPS will be made by Incident Command pursuant to Section 4.3.4 of this Plan. KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 14 DECEMBER 31,2025 • Remote sensing, weather stations, and satellite imagery to identify high-risk areas. • Fuel moisture levels, including Dry Vegetation/Fuel Moisture Criticality: Dry grasses, shrubs, and trees, based on local fuel moisture readings.

If a PSPS is initiated,the ICT: • Will direct the opening of devices to de-energize affected lines, and • Confirm with field teams that de-energization has occurred safely. KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 16 DECEMBER 31,2025 4.3.5 Monitoring During a PSPS During any PSPS,the ICT will take, or will direct, the following steps until restoration is complete: • Patrol and monitor de-energized lines for safety hazards, • Coordinate with emergency services for any incidents, • Take reasonable steps to identify and provide on-site support for critical members, and • Provide public regular updates, including estimated restoration times (if available). 4.3.6 Restoration Process After a PSPS After the ICT determines that a PSPS is no longer necessary, Operations will begin the re-energization protocol. Under the re-energization protocol, Operations will: • Conduct line inspections, • Clear vegetation and hazards, • Verify system integrity and readiness, and • Restore power. Communications will take steps to notify customers of restoration progress. 4.3.7 Post-Event Review As promptly as reasonably practical after a PSPS has occurred and restoration is complete,the PSPS Review Management Team (which will include representatives from all teams involved in the PSPS event) will conduct an internal after-action review. The internal after-action review will include a review of the following: • Response timeline, • Communication effectiveness, • System and personnel performance, and • Public and agency feedback. Upon completion of the internal after-action review,the PSPS Review Management Team will create an after-action report and, if necessary, will update the PSPS process/procedures in this Plan based on lessons learned. 5. Outreach and Communication 5.1 KEC Internal Processes to Guide Wildfire-Related Communication KEC will adhere to established internal processes for wildfire-related communication. KEC will share information about its Wildfire Mitigation Plan, including details on PSPS,with members, employees,the public,the media, and other stakeholders (including federal, state,tribal, and local agencies). KEC will,to the extent practical, communicate any anticipated or actual PSPS with any neighboring utility that may be impacted by the PSPS. KEC anticipates that neighboring utilities will similarly share information regarding any anticipated or actual de-energization that will impact KEC. To the extent that KEC obtains information from another utility regarding any de-energization that will impact KEC, KEC will integrate such information in its operational planning.10 11 The only other utility in the area that is likely to impact KEC's operations is Avista Corporation. KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 17 DECEMBER 31,2025 5.2 Coordination with Federal,State,Tribal,and Local Agencies 5.2.1 Annual Coordination Meeting Prior to May 1 of each calendar year, KEC will schedule and host (or if a similar meeting is scheduled and hosted by another entity, participate in) a meeting ("Annual Coordination Meeting") with, as applicable, federal, state,tribal, and local officials and agencies to coordinate on wildfire preparedness and emergency response plans. To the extent that KEC schedules and hosts the Annual Coordination Meeting, KEC will invite applicable federal, state,tribal and local officials and agencies, including without limitation,the OEM, Kootenai County Fire Chiefs, Coeur d'Alene Tribe Police Chief, and the Idaho Department of Lands to the Annual Coordination Meeting. The Annual Coordination Meeting may be held in person or virtually or both. 5.2.2 Communication of Changes in Operating Condition Whenever the NFDRS rises to "High" or above (or a Red Flag Warning Day), KEC will notify OEM,the Coeur d'Alene Tribe Polce Chief, and Idaho Department of Lands of a potential of a change in operating condition. 5.2.3 Communications with OEM Regarding PSPS With regard to PSPS, KEC will notify OEM as follows: • At any time that KEC determines whether a PSPS is likely or imminent, KEC will notify OEM of the potential of a PSPS and the potential areas on KEC's electrical system that may be affected by a PSPS. • When there is a PSPS, KEC will notify OEM that a PSPS has occurred,the areas on KEC's electrical system that are impacted by the PSPS and, if available, an estimate of how long the PSPS will be in effect. • When the event requiring a PSPS has passed and KEC begins the restoration process, KEC will notify OEM that it has commenced restoration and, if available,will provide an estimate of how long it will take for KEC to restore its electrical system. • Upon completion of the restoration process after a PSPS, KEC will notify OEM that restoration is complete. Upon notification from KEC, OEM will notify other state and local agencies. 5.3 Member Communications KEC's wildfire-related communication goals are as follows: • Educate members about KEC's approach to wildfire prevention and mitigation. • Inform members about the current wildfire conditions and any actions that KEC may take to mitigate wildfire risk, including any operational conditions/limitations on KEC's system and any PSPS. • Prepare members for PSPS or other wildfire-related outages, including reminders to update their contact information, report outages, access updates on system conditions/outages, and access safety/preparedness tips. Before the wildfire season begins, KEC will communicate broad messages about safety and preparedness to KEC's membership. As weather events or system changes occur, KEC will direct more targeted KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 18 DECEMBER 31,2025 messages to members affected by the changes. Below are the communications channels used to share wildfire and outage related messages to KEC's members: • Powerl-ines monthly member newsletter, which is included in member billing statements (an e- version is also sent to all member email addresses). • KEC's website: www.kec.com.This is a source of information and education about wildfire, safety, and outages for members. It is updated regularly. • Social media: KEC regularly updates its Facebook and Instagram pages with timely information and updates about outages, safety and wildfire. • News releases are used as needed to provide information to local media outlets. • KEC sends an annual wildfire email to all members. KEC also sends targeted emails and/or text/SMS to members affected by outages.These methods will also be used to communicate with members that may be affected by a fire mitigation mode adjustment or a PSPS. Due to KEC's rate structure, members with needs or infrastructure that they deem to be critical are expected to provide their own redundancy and/or backup to provide power in the event of de- energization. Therefore, KEC currently does not identify any critical infrastructure and/or members. To the extent KEC identifies any critical infrastructure and/or members in the future, KEC shall maintain a list of such critical infrastructure and/or members and shall provide targeted communications to such critical infrastructure and/or members via email,text/SMS, or other appropriate communication method. 6. Cost Evaluation; Cost-Benefit Approach The Wildfire Standard of Care Act requires wildfire mitigation plans to identify a means for mitigating wildfire risk that reflects a reasonable balancing of mitigation costs with the resulting reduction of wildfire risk. This includes financially prudent and reasonably practicable methods of line design for new, planned, and existing lines to mitigate fire risk.11 In Order No. 36774,the Commission ordered that electric corporations must (i) explain how an electric corporation's line design methods reduce the potential for wildfire ignition, including a cost evaluation, and (ii) include a cost benefit analysis in their proposed wildfire mitigation plans that justifies the expenditures for risk mitigation described in such wildfire mitigation plans.12 The costs incurred by KEC, including costs incurred pursuant to its construction work plan,vegetation management plan, and inspection plan, are incurred for multiple purposes. Those purposes include, among other things, extending service to members, enhancing reliability, replacing outdated infrastructure, and wildfire mitigation. It is not possible to determine the amount of each expenditure that is properly allocated to wildfire mitigation as opposed to some other purpose. Accordingly, in evaluating any project, KEC evaluates all of the needs and benefits associated with the project to determine whether the costs of the project are justified. It is also not possible to obtain a precise calculation of the potential costs of future wildfires.13 As noted by Idaho Power: " Idaho Code§61-1803(3). 12 Order No.36774 at 20. 13 See Idaho Power Company's 2026 Wildfire Mitigation Plan,filed in Case No. IPC-E-25-32,at page 15 (stating: "Ultimately, Idaho Power found that obtaining a precise calculation of the potential costs of future wildfires is not possible."). KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 19 DECEMBER 31,2025 publicly available analyses of recent wildfires illustrate the magnitude of potential avoided costs when prudent mitigation reduces the likelihood or consequences of catastrophic events. For example, in Idaho,the Moose Fire in 2022—which grew to approximately 130,000 acres— cost approximately$ 100 million to suppress, as did the Pioneer Fire in 2016.The Charlotte Fire in Pocatello ( 2012) destroyed 66 homes, burned approximately 1,038 acres, and estimates at the time gauged damages at$12 million,though officials noted that timely response helped protect approximately$472 million in property value. In eastern Washington in 2023,the Gray and Oregon fires together destroyed over 350 homes and caused multiple fatalities. Costs and damages associated with the 2020 Idaho wildfire season alone are estimated between $100 to $250 million. In more catastrophic events outside of Idaho, the costs are exponentially higher.The recovery costs of the Maui wildfires in 2023 are expected to exceed $ 2 billion, and in California, costs and damages associated with the 2025 Los Angeles wildfires are estimated between $28. 0 billion and $53. 8 billion." This data supports the conclusion that the costs of KEC's wildfire mitigation efforts set forth in this Plan are reasonable expenditures to avoid the potential costs associated with a wildfire. KEC is a member-owned non-profit corporation. KEC is not a public utility subject to rate regulation by the Idaho Public Utilities Commission. Rather, KEC is governed by its board of directors. KEC's board of directors has reviewed this Plan and its costs of implementation and has determined that the Plan (i) includes financially prudent and reasonably practicable methods of line design for new, planned, and existing lines to mitigate fire risk; (ii) is feasible; and (iii) reflects a reasonable balancing of mitigation costs with the resulting reduction of wildfire risk. KEC Resolution#10-25 is attached hereto as Appendix D. 141d. (internal footnotes omitted). KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 20 DECEMBER 31,2025 Appendix A Vegetation Management Plan Incorporation in Wildfire Mitigation Plan. This Vegetation Management Plan (VMP) is incorporated in, and is part of, Kootenai Electric Cooperative, Inc's ("KEC") Wildfire Mitigation Plan. Purpose. The purpose of vegetation management performed by KEC is to identify and control or eliminate vegetation that threatens the integrity, reliability, or safety of the electrical facilities that are part of KEC's electrical system ("KEC Facilities"). This VMP provides the general standards and guidelines for KEC's performance of vegetation management. VMP Implementation Schedule. Vegetation management includes pruning and removing tree and brush species in the areas around KEC Facilities, the proper disposal of debris created by those activities, and other steps necessary to identify and control or eliminate vegetation that threatens the integrity, reliability, or safety of KEC Facilities. Each calendar year, KEC shall develop a VMP Implementation Plan for the next calendar year. Each VMP Implementation Plan shall (i) identify the KEC Facilities (or portions of the KEC electrical system) where vegetation management is scheduled to be performed in the applicable calendar year; (ii)the resources that will be required to perform the scheduled vegetation management(including the anticipated KEC personnel, total number of personnel hours, KEC contractors, and equipment necessary to perform the scheduled vegetation management activities); and (iii)the steps to be taken to document and report the work that is performed pursuant to the VMP Implementation Plan Each VMP Implementation Plan will also include projected VMP Implementation Plan for the calendar year immediately following the first calendar year. For example,the VMP Implementation Plan that is developed in 2025, will include the VMP Implementation Plan for 2026 and a projected VMP Implementation Plan for 2027. Right-of-Way Clearing and Trimming. KEC's standard practice is to maintain a 30-foot area around its overhead and above-ground electric facilities operating at distribution voltages. KEC's standard practice is to clear everything within 15 15' fifteen (15)feet of the centerline of its overhead and above- ground electric facilities operating at distribution voltages as illustrated in the graphic below. KEC will perform vegetation management in accordance with its standard practice of clearing everything within fifteen (15)feet of the centerline of the KEC Facilities, except as otherwise required by applicable federal, state, or local laws, regulations, or ordinances ("Applicable Laws"). In addition to clearing everything within 15 feet of the centerline of the KEC i Facilities, KEC will also remove any hazard trees as discussed herein. Figure 1 ROIL/Clearances In those circumstances where clearing in accordance with the standard practice stated above is either not permitted or is impractical, pruning will be performed in a manner that is consistent with best management practices as published by the International Society of Arboriculture (ISA) guidelines, including ANSI A300, applicable OSHA KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 21 DECEMBER 31,2025 requirements, and all Applicable Laws. Such pruning will be performed to remove dead/dying branches and other parts overhanging, encroaching, or otherwise threatening any KEC Facilities. Vegetation Management Practices • Residential:Vegetation that is cleared or pruned will be masticated. Debris will not obstruct roads, ditches, or drains.To the extent practical, KEC will discuss any pruning or clearing of ornamental plantings with landowners before work begins.Topping is not an accepted practice. • Rural and Undeveloped Areas:Vegetation that is cleared or pruned will be masticated, and scattered. Live and dead trees will be felled and arranged parallel to power lines without blocking roads, streams, or ditches. System-Wide Assessment Using All &Satellite Imaging. KEC will assess its electrical system every two (2)years using an AI-powered vegetation intelligence system,which provides wildfire risk analysis, hazard tree identification,tree segmentation, height and health analysis, 3D vegetation risk scoring, and recommended work prioritization. The Encroachment Risk Rating system classifies vegetation risks as: 1. High (0-3 feet from conductor) 2. Medium (3-6 feet) 3. Low (6-10 feet) 4. Minor 5. Clear Vegetation Management Schedule and Prioritization. KEC performs vegetation management on a seven (7)year cycle in accordance with its VMP Implementation Plan. Vegetation management to be performed in each year of the cycle shall be included in the VMP Implementation Plan for such year and will be organized by feeder and prioritized based on historical outage frequency and duration. Vegetation management that is required to be performed in a calendar year that is not included in the VMP Implementation Plan for that year (including, service order work) is prioritized based on an assessment of the Encroachment Risk Rating as follows: • Priority 1 (High Encroachment Risk):Addressed within the year identified. • Priority 2 (Medium Encroachment Risk):Addressed after Priority 1 within two (2)years after identified. • Priority 3&4(Low and Very Low Encroachment Risk):Addressed in the normal course within the seven (7)year cycle. Hazard Tree Mitigation. Hazard trees are trees that are identified as dead, dying, or structurally damaged that pose a risk to KEC Facilities. Hazard trees outside a right-of-way that present a fall risk are continuously evaluated and prioritized for removal. Priority is assigned based on U.S. Forest Service wildfire zone data. KEC's field planners will assess the Encroachment Risk Rating of each hazard tree that is identified and will assign work accordingly. KEC will, in accordance with KEC's Vegetation Management Policy, remove any hazard tree that is outside the right-of-way(or outside of the 30-foot KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 22 DECEMBER 31,2025 area cleared of vegetation in accordance with KEC's standard practice) if such hazard tree reasonably threatens KEC's facilities. Member-Reported Service Orders& Emergency Response. Member-reported concerns will be assessed by a KEC representative. If the request involves vegetation that is encroaching on any KEC Facilities, work will be performed per specifications and this Vegetation Management Plan. Underground Structures. KEC's crews must be able to inspect utility equipment at all times. Any obstruction that impedes access to KEC facilities will be removed to allow immediate access. Cleanup. Logs that are left after performing vegetation management will be cut into tree lengths, unless the member/landowner requests that such logs be cut into firewood lengths. Stumps will be cut as close to ground level as practical. Stump removal is not performed by KEC. All wood is left for property owners. Brush and limbs from live trees will be chipped or lopped and scattered,while those from dead trees will be left for the property owner. Secondary Line Trimming. Members are responsible for vegetation management for secondary service lines. KEC does not generally perform vegetation management for secondary service lines, but KEC may, in its sole discretion, perform such vegetation management. KEC will provide line drops free of charge for members to trim trees affecting secondary service lines. Member Communication. Members will be notified before circuit trimming begins. KEC will make reasonable efforts to notify other(non-member) landowners. In the event that any landowner(member or non-member) denies KEC access to perform vegetation management in accordance with this Vegetation Management Plan, KEC will provide such landowner notice in accordance with the Wildfire Standard of Care Act of its intent to access and perform vegetation management. Conclusion.This document serves as KEC's official Vegetation Management Plan. This Vegetation Management Plan is supported by KEC's Vegetation Management Policy,Vegetation Management Procedure,which reference and guide vegetation management activities. KOOTENAI ELECTRIC COOPERATIVE INC.WILDFIRE MITIGATION PLAN-PAGE 23 DECEMBER 31,2025 Appendix A-1 2026-2028 Vegetation Management Implementation Plan Vegetation Management Implementation Plan 2026-2028 Overview This Vegetation Management Implementation Plan (VMIP) outlines how Kootenai Electric Cooperative, Inc.

These audits will support continuous quality assurance and help validate contractor performance and cycle effectiveness. Resource Planning KEC will estimate the number of personnel and labor hours required to complete each year's scheduled work and will staff crews accordingly. These estimates will be informed by historical workload and circuit characteristics. Every two years, following receipt of updated Overstory Al and satellite vegetation data, resource requirements will be re-evaluated and adjusted as needed to ensure alignment with vegetation growth patterns, encroachment risk trends and hazard tree counts. Projected expenditures for right-of-way(ROW) clearing are as follows: • 2026: $5,686,609 • 2027: $5,857,207 • 2028: $6,032,923 Review Cycle This Implementation Plan will be reviewed and updated annually in conjunction with the VMP and will include projections for the subsequent three calendar years. Adjustments will be based on Overstory assessments, work audits, member requests, and unplanned events such as storm response or wildfire emergencies. This document supports and aligns with KEC's Vegetation Management Plan and associated policies and procedures.
