On August 15, 2025 we received an email stating that “The DOE is working to complete the data review process as expeditiously as possible and will be in contact as soon as possible.” DOE Contract Status AEA’s initial award covered a project budget period ending June 30, 2025. A formal “Go” decision recommendation was submitted to DOE on May 9th based on preliminary design documentation confirming the project can be completed on time and within budget. DOE technical staff indicated concurrence with AEA’s recommendation to proceed. A continuation request and cost estimate for Budget Period 2 (July 1, 2025 – June 30, 2027) was submitted to DOE in mid-May. DOE’s technical and contracting representatives provided verbal confirmation of support for continuing into Budget Period 2. However, execution of a continuation agreement is pending authorization from the DOE Process Review Team. As a result, contract execution for procurement, environmental and FEED-related work has been postponed. Project development activities are continuing in the interim to remain on schedule. AEA determinied that we need to continue working on the project so we authorized two task orders: 1)Environmental Review - Following submission of the Data Request package, a NEPA Environmental Questionnaire was provided to DOE in support of Budget Period 2 scope of work. A Categorical Exclusion determination was issued within 10 days, enabling environmental and fieldwork activities to proceed in Summer 2026. AEA awarded a Task Order to HDR to complete the environmental work needed to be executed next summer. 2) Development of major equipment procurement documents – Stantec will assist AEA with planning, solicitation, and procurement contracts for major items of supply, in particular the HVDC converters and the HVDC cable. These items are expected to have very long lead times, on the order of several years. This task will build on information gained during earlier execution of the earlier tasks including: preliminary design, the budgetary costs, and the project schedule Alaska Energy Authority Page 2 of 2 (Task 1). Work on this task will include: 1) Determine contracting strategy for the HVDC cables and converters, 2) Prepare and issue a solicitation of interest / request for information (RFIs) to converter and cable suppliers to solicit interest, 3) Obtain budgetary pricing, preliminary delivery schedule, and technical information. AEA expects that the HVDC Converter procurement will be for a full EPC turnkey contract, on a negotiated, preferred supplier basis, not a competitive procurement of converters. AEA expects that the Cable procurement is assumed to involve a combined supply and install contract on a competitive basis; contract may also evolve into a preferred supplier basis depending on RFI responses. Financial Status and Cost Share Strategy AEA has secured $64.2 million in combined state appropriations and Bradley bond proceeds. An additional $142.3 million is being sought to fully meet cost share obligations. To date, $1,411,881 has been spent on the project AEA is reviewing financing options to secure the balance of the funding, including; 1) Loans (Focus on DOE Loan Program Office) 2) Private Debt 3) P3 Arrangements 4) Private Equity MEMORANDUM TO: Bradley Project Management Committee Through: Curtis Thayer, Executive Director FROM: Ryan McLaughlin, PE, Senior Infrastructure Engineer DATE: September 19, 2025 RE: Bradley Lake Expansion Project Update Engineering Design and licensing efforts are ongoing, with a target submittal of the Draft License Amendment Application by January 2026. To ensure consistency and clarity throughout the FERC licensing documents, design deliverables, and environmental reports, the overall project will be called the “Bradley Lake Expansion Project” and sub-projects defined as follows: Bradley Lake Expansion Project o Dixon Diversion ▪ Diversion dam and tunnel inlet portal features ▪ Diversion tunnel ▪ Diversion tunnel exit portal features ▪ Exit portal access road o Bradley Pool Raise ▪ Spillway crest raise ▪ Dam crest raise Crews and equipment mobilized to Bradley by barge over the weekend to begin drilling and geophysics at Bradley Dam. Over the next month 9 boreholes will be drilled through and around Bradley Dam to set up monitoring, test stability, and collect samples of embankment material. Additional geophysical surveys will be completed at the Bradley Dam and the Dixon Diversion site. Equipment is onsite and first borehole is expected to spud on 9/15. The Drilling Plan Program has been approved for FERC and AEA has received a DNR temporary water use authorization permit for the work. AEA and DOWL will be onsite 9/17-18 to complete annual operator training and safety inspection of the Bradley Dam. This site visit will also include a trip to the Dixon Diversion Dam site for the project engineers to evaluate current design against site conditions. The next Board of Consultants meeting has been scheduled for October 29-31. This meeting will review results from the PMP/PMF study, initial drilling results, and design documents. AEA has responded to FERC comments on the PMF Scope of Work. Study is ongoing, but initial results suggest PMP is slightly lower and PMF is slightly higher (larger drainage area) compared to the original studies done in the 80’s. AEA submitted an Inflow Design Flood recommendation (IDF) to FERC for the future Dixon Diversion Dam. This was done using a conservatively estimated 100-year flood of 7,900 cfs. 100- year flood is a common IDF for low-hazard dams, AEA is waiting on FERC acceptance of the low- hazard classification for the Dixon Diversion Dam. Battle Creek Diversion and Bradley Dam are both low-hazard, no structures or populations below the Dixon Diversion Dam, so it is expected that the Dixon Diversion Dam will be low-hazard. The design for 3-phase power from Bradley powerhouse to the dam is at 65%. EPS is on track to complete the design and bid package by next summer in order purchase cable and transformers in time for shipment and delivery for a summer 2027 install. A decision has been made to fully line the Dixon Tunnel. This will have minimal cost impact to the project compared to previous cost estimates, improve worker safety (24/7/365 operations inside tunnel), improve hydraulics (no chokepoints), and reduce construction risk (many sections may need lining anyway). A design criteria has been established for a 14’ minimum finished inside diameter tunnel (16’ tunnel w/ 1’ concrete liner) which will provide up to 1650 cfs of flow. This balances cost of a larger tunnel vs additional capacity of higher future flows. Environmental Aquatic, terrestrial, and cultural resources studies and summer 2025 field season is on schedule, as per approved Study Plan. This is the final summer of environmental studies. An August 29th stream gaging trip had the highest spot measurement of discharge recorded on Martin River – 2490 cfs at the constriction. This will be very useful in continuing to build out the stage-discharge relationship on the Martin River as many measurements have been collected at mid flows, few at high flows. ADFG counted 1479 sockeye through Red Lake, the highest count in three years of monitoring. The Red Lake monitoring site is getting unsafe to access as Martin River channel is cutting through to the video monitoring site. The next site visit with ADFG/DOWL will need to cut a new landing zone. The Coho run is ongoing and ADFG is hoping the video site isn’t destroyed by high flows until the run is complete. Landing Zone: low vs high flow 813 W Northern Lights Blvd, Anchorage, AK 99503  Phone: (907) 771-3000  Fax: (907) 771-3044  Email: info@akenergyauthority.org REDUCING THE COST OF ENERGY IN ALASKA AKENERGYAUTHORITY.ORG MEMORANDUM TO: BPMC THROUGH: Curtis Thayer, Executive Director FROM: Jim Mendenhall, P.E., Program Manager DATE: September 15, 2025 SUBJECT: Transmission Upgrades – Sterling to Quartz Creek & Soldotna to Sterling The Sterling Substation to Quartz Creek Transmission Line (SQ of SSQ Line) •Overall length of the SQ Line is 39 miles. •Prior to AEA’s acquisition of the SQ Line it was owned by Homer Electric Association. •This section was damaged in 2019 during the Swan Lake Fire, and was unusable. •The Alaska Energy Authority's acquired the line in late 2020 to repair it, and enablefuture upgrades. Specific benefits include: better cost alignment for customers,increased reliability, and future prospects for upgrades to decrease line losses andallow more power transmission from Bradley Lake. The SQ Line was identified asRequired Project Work under the Bradley Power Sales Agreement. As such, it isdeemed a critical component of the interconnected Railbelt transmission system,needed to ensure the consistent delivery of low-cost, renewable hydroelectric powerfrom the Bradley Lake Hydroelectric Project to population centers. •The SQ Line is currently being upgraded from 115kV to 230kV standards to increase its capacity and resilience. •Bradley Lake hydro has a nameplate generating capacity of 120MW. However, the maximum transfer capacity on the SQ line is significantly less. The reason for the limitation is that the current transmission system is limited to an absolute maximum of 75MW for thermal over load and stability limitations. Note: At 75MW of power transfer, losses are ~10%. The SQ Upgrade Project •The project is broken into three phases o Each of the projects needs to have approximately a 40-day outage of the transmission line. o Phase 1 -The section is the 8 miles between Sterling and Johns Road and was completed during the winter of 2024/2025. Field conditions for Phase 1 were difficult due to the warm weather and required ground matting to support the equipment. The section was as completed and energized to 115kV on February 28, 2025 Alaska Energy Authority Page 2 of 4 o Phase 2 – Will upgrade 17 miles through the Kenai National Wildlife Refuge. This section will be constructed in the winter 2026/2027. When complete it will be energized to 115kV. o Phase 3 (previously 3 & 4) – Will upgrade 14 miles from The Russian River to the Quartz Creek Substation (CEA). This section will be constructed during the winter 2028/2029 •Once all 3 projects are completed and CEA completes the upgrades between Quartz Creek to Anchorage, HEA completes the SS (Soldotna-Sterling) and all upgrades at substations are complete the entire circuit will be energized to 230kV.

Moreover, the commiƩee is commiƩed to addressing and eliminaƟng large-scale, small-signal instability oscillaƟons that arise when the Bradley Project interacts with the summer valley during periods of low lake levels. Consistent with SecƟon 32 of the Power sales agreement, which commits the parƟcipants to seek a high-capacity interƟe between the Kenai and Fairbanks, a comprehensive regional transmission plan, named the Grid ModernizaƟon and Resiliency Plan (GMRP), has been developed. The implementaƟon of GMRP is expected to yield several ancillary beneﬁts, including a more resilient and robust grid capable of withstanding extreme weather events and other disrupƟons. The modernizaƟon efforts will enhance power transfer capabiliƟes between regions, reduce the need for thermal reserves, decrease fuel consumpƟon, and cut carbon emissions. AddiƟonally, the upgraded grid will beƩer accommodate variable clean energy sources. This report outlines our acƟviƟes related to these efforts over the months of August and September. Contractors:  None Grant Efforts: State Match efforts The Legislature adjourned with minimal acƟvity in this area. Looking Forward: No speciﬁc acƟons are on the horizon, unless DOE iniƟated GRP cycle three funding. Other AcƟviƟes:  As noted previously, on April 3rd, I transiƟoned to a reduced (40%) role at EDRRC as I begin assisƟng the Seward Electric System with their uƟlity management. However, I will conƟnue to oversee the Federal Grant applicaƟons process and aid as required in state and uƟlity match efforts. 2 This report reﬂects our conƟnuous commitment to enhancing the Railbelt region's energy infrastructure and resilience, marking signiﬁcant milestones in our journey towards a more sustainable and efficient energy future.

This increase in flow carried gravel into the diversion forebay that eventually overwhelmed the sediment blocks and carried over to the Mif gate. The Mif gate became partially plugged with gravel restricting flow to Battle Creek. The Mif gate was fully open to flush the gravel downstream. We were able to restore normal flow through the Mif gate but discovered that part of the support bracket had been damaged and prevented the gate from closing more than 50%. The flows are currently too high to access the Mif gate to make repairs. • Safety – There have been no lost time or reportable accidents for the months of July, Aug., and as of this date in Sept. 2025. Safety meetings were conducted in July, Aug., and Sept. 2025. Next safety meeting is Oct. 8, 2025. DOWL will conduct Dam Safety Training for the Operators on 17 Sept. 2025. • Unit #2 Breaker- EPC will be in on Sept. 24-25, 2025, to complete the final mechanical adjustments to the breaker. • Halon Fire System replacement- The Fire Marshal completed his review of the design. The materials have begun to be shipped to Homer. An installation date is pending for Late Oct. 2025 • The RFB for the upgrade of the fire alarm system received no proposals. • Fire system inspection and testing scheduled for 11 Sept 2025 was cancelled due to weather. The plane was grounded due to dense fog that lasted all day. Bradley Lake Operators Report Page 2 • Fire Huts - New fire huts that house the fire hydrants, portable fire carts, hoses and miscellaneous tools have been installed. • Personnel- We currently have one open Operator Position.
