Mr. Ziesmer summarized the report as of December 31, 2025. Actual revenues exceeded the budget by $118,500, primarily due to IMC Meeting Minutes – March 20, 2026 3 higher than anticipated energy usage. The total energy usage exceeded the budget by about 2,500 MWH. The interest accrued from the start of the fiscal year through December 31, 2025, totaled $36,750. The operating expenses were below budget by approximately $1.12 million year-do-date. Several expense categories have seen little or no activity so far. Mr. Ziesmer highlighted that the Maintenance of Station Equipment Douglas Substation category 57000 is over budget by $41,409. The overage is related to work performed on the Douglas Substation Communications upgrade. The budget amendment that was approved earlier in the meeting increased this line item from $105,000 to $505,000. This will fully capture the costs and bring the budget back in line. The Douglas Substation line item is over budget by $140,172. The same budget amendment approved today also increases the budget for this line from $150,000 to $250,000 and addresses this overage. Mr. Ziesmer discussed that the Miscellaneous Administration and IMC Administrative Costs category 58306 is over budget by $44,898. This is mostly related to the legal costs regarding the Railbelt Transmission Organization (RTO) and responses to the Regulatory Commission of Alaska (RCA). AEA’s Administrative Support Expenses are over budget by $22,312. This increase is due to higher internal payroll and indirect costs largely tied to RCA related work. In summary, the Intertie shows a surplus of approximately $1.72 million as of December 31, 2025. There were no comments or questions. 9B. IOC Report Mike Miller, CEA, presented the IOC Report. Mr. Miller noted that the report includes updates on the Douglas Communications. It is anticipated that the communication equipment will be installed in the new enclosure at the end of the month. Mr. Miller discussed that the Snow Unloading Project received the necessary signatures on the cost-share agreement. That project is moving forward to complete a request for proposal (RFP) for design in April. Mr. Miller discussed that the System Studies Subcommittee (SSS) provided a presentation at the previous IOC meeting on the Inverter-Based Renewable (IBR) Study. The memorandum submitted is being reviewed and IOC members are expected to provide feedback. That information and recommendations will then be presented to the IMC. The information will include suggestions regarding rate of change and frequency thresholds, short circuit ratings, and voltage recovery criteria. Mr. Miller looks forward to providing additional information in the future. Mr. Miller commented that EPS submitted a final report regarding the 230 kV Upgrade Impact Study for the northern tie. The report is under review. Mr. Miller highlighted that GVEA has taken the lead in the improvement efforts for the assignment for the Alaska Intertie Communications. Biweekly meetings are being held with the Telecom Subcommittee. Mr. Miller noted that the Southern Intertie Stability and Losses Study has not made any progress due to an issue with the handoff between the outgoing SSS Chair and the incoming SSS Chair. However, that study has now been identified as a priority. IMC Meeting Minutes – March 20, 2026 4 Mr. Bishop commented that he is glad to see the Railbelt EMT Model and hopes the work will continue to understand relevant impacts and issues. Mr. Miller explained that at the previous IOC meeting, the SSS Chair discussed the EMT Model work and the draft RFP that they are developing and reviewing. The schedule is on track to solicit bids and will potentially incorporate efforts in the 2027 Budget. There were no other comments or questions. 9C. Operator Report Mr. Miller presented the Operator Report dated March 20, 2026. The year-to-date usage is consistent with what was seen in the previous year. The usage is still down by about 50%. This is associated with less sales or exchange in MW between the southern utilities and GVEA. There were no identified trips for the Intertie between January and March. Regarding the IOC Quarterly Reliability Report, there was a fair amount of activity between January and March that is noted, including several trips that occurred at Healy 2 and the underfrequency load shed (UFLS) event that occurred on March 4, 2026. Generally, the response is approximately 10 MW/0.1 Hz. Mr. Laughlin highlighted that there are five Healy 2 trips listed. He requested additional context regarding those events. Mr. Miller explained that he does not have any specific information about the nature of the trips at Healy 2. Mr. Bishop believes that some of the Healy 2 trips are related to difficulties with pole quality due to weather. Mr. Price noted that over the last couple of months, more Intertie usage has been pulled than has been budgeted due to the cold snaps and cold issues. He asked GVEA if that trend is expected to continue for this budget year. Mr. Bishop responded that he does not have that information today. He will get the information and then provide an answer at a later time. An unidentified speaker commented that the surplus becomes bigger, the more the usage occurs. Mr. Bishop expects that GVEA would like to purchase more power, but that is dependent on availability. Chair Zellers believes that the cold snap will end, and that the load will return to the normal budgeted amount. He noted that Bradley Lake has scheduled upcoming outages. There were no other comments or questions. MOTION: A motion was made by Mr. Laughlin to enter into Executive Session to discuss confidential matters that 1) the immediate knowledge of which would clearly have an adverse effect upon the finances of AEA, the Intertie, the IMC, or any of its members, 2) matters involving consideration of records that by law are not subject to public disclosure. Motion seconded by Mr. Bishop. A roll call vote was taken, and the motion to enter into Executive Session was approved unanimously. IMC Meeting Minutes – March 20, 2026 5 10. EXECUTIVE SESSION: 9:21 a.m. – (Bylaws Section 5.11.3) To discuss confidential (1) matters the immediate knowledge of which would clearly have an adverse effect upon the finances of AEA, the Intertie, the IMC, or any of its members; (2) matters involving consideration of records that by law are not subject to public disclosure. The Committee reconvened its regular meeting at 9:53 a.m. Chair Zellers advised that the Committee did not take any formal action on the matters discussed while in executive session. 11. MEMBERS COMMENTS Mr. Bishop thanked counsel for their professional efforts on behalf of IMC, and thanked members who participated, including the staff, subcommittees, and accounting individuals who support the efforts of this organization that provides significant benefits to the Railbelt. Mr. Laughlin echoed Mr. Bishop’s comments, specifically to counsel and Chair Zellers for attending the RCA RTO hearings. He thanked staff for their reports and information today. Mr. Price echoed the previous sentiments. Chair Zellers echoed the comments of appreciation for the recent efforts regarding the RTO. 12. NEXT MEETING DATE – May 1, 2026 Chair Zellers indicated that the next meeting date is May 1, 2026. 13.

CEA is looking at comms installation delayed due to man power limitations. Anticipated completion is July. The scope of the project expanded due to the need for a new communications shelter and land use agreements, which increased costs. b) Synchrophasor Project: Project continues with biweekly meetings, including a project manager group and a separate IT/communications-focused group. Software contract in review with AEA. c) Snow Unloading Project: The cost-share agreement for the snow unloading project is complete. A RFP for a design consultant has been issued with bids due in May. d) FY2027 Budget: All participant budget items provided and reviewed by IOC on 4/24/2026. e) PSS/E Model Sharing: Some participants and AEA have been asked by third parties to provide the Railbelt Model for undefined private analysis assumed to be related to potential IPP developments. The IOC debated proper course of action. Among options discussed were requiring requests be submitted through the IMC for the model or not engage in model sharing with third parties until RRC model ownership/processes are established. 2) System Studies Subcommittee a) IBR Study: Final report complete. IOC discussed memorializing study screening criteria and recommendations (e.g., via an SSS memo) and routing to IMC for awareness/possible adoption as planning guardrails, consistent with prior study precedents. b) 230kV Upgrade Impact Study: EPS submitted final report. c) Railbelt EMT Model: RFP development complete and RFP release is dependent on FY2027 Budget d) Railbelt Governor tuning/coordination: Due to SSS resource availability and the other study initiatives in progress, this study is being postponed for the time being. (Dependent on FY 2027 budget and direction from the IMC.) 3) Relay, Protection, & Control Subcommittee a) No update 4) SCADA/Telecommunications Subcommittee a) Improvements to Alaska Intertie Communications: Utilities coordinated to move off the AT&T circuit in April. Mea is working on a leased path with MTA for IP connectivity for ICCP redundancy. 5) Operations, Maintenance, and Scheduling Subcommittee a) No update Intertie Management Committee Meeting Operator Report May 1, 2026 1.

Alaska Intertie trips to report There were no trips of the Alaska Intertie in the months of March - April. 3. IOC Quarterly Reliability Report For generation trips or transmission line trips where the loss of load is known, the Railbelt-wide frequency response is calculated. The magnitude of the tripped power and the change in frequency from the pre-trip value to the peak or nadir are used to calculate the MW/0.1Hz value often known as ‘Beta’. Chugach has calculated the Beta for several events and the table of the results is provided below. Events without data for the MW magnitude of the trip were excluded, as were events that did not cause a frequency deviation greater than 0.2 Hz.
