ADJOURNMENT Bradley Lake Project Management Commitee Repo rt on Railbelt Regional Coordina�on Overview: The Bradley Lake Project Management Commitee aims to both increase the project's capacity limit from its current level of 90 MW to its full capacity of 120 MW, and to ensure that energy and capacity are reliably and resiliently delivered to each of the project par�cipants. In addi�on, the Commitee seeks to eliminate large-scale, small signal instability oscilla�ons that arise when the Bradley Project interacts with the Summer Valley system during low lake levels. To achieve these objec�ves, the commitee has undertaken the development of a high-level regional transmission plan, known as the Grid Moderniza�on and Resiliency Plan (GMRP). The implementa�on of this Plan will result in various ancillary benefits to the grid. These benefits include an enhanced, resilient, and hardened grid that can withstand extreme weather and other disrup�ve events. Moreover, the modernized grid will be able to transfer more power between regions, reducing thermal reserves and resul�ng in lower fuel burn and carbon emissions. Addi�onally, the upgraded grid will have an improved capacity to integrate variable clean energy sources into the system. The following report provides a summary of our ac�vi�es with respect to this effort in the months of February, March, and April. It outlines the grant applica�ons filed, their details, and the progress made on them. Addi�onally, it highlights other ac�vi�es undertaken related to this task, including mee�ngs and presenta�ons. Grant Applica�ons: We have engaged several consultants to accomplish this effort including Electric Power Systems, Lee Thibert and Associates, Agnew Beck, LSI and Brownstein Hyat. The months of February, March, and April have been primarily devoted to developing and filing grant applica�ons. Two grant applica�ons were completed and filed during this period. The first was the GRIP Topic 2 Smart Grid applica�on, which was completed and filed on March 17th. The project aims to create a real-�me coordinated control system for three Batery Energy Storage Systems (BESS) and the High Voltage Direct Current (HVDC) Submarine Cable. The total project cost is $32.2 million, and the grant request is for $16.1 million, which requires a $16.1 million match. The second grant applica�on was the GRIP Topic 1 applica�on, which was completed and filed on April 5th. The project aims to rebuild exis�ng transmission lines from the Bradley Project to the Daves Creek substa�on, Eklutna Hydro to Lucas, and Teeland to Douglas to 230 kV. The total project cost is $402 million, and the grant request is for $100 million, which requires a $30 million match, and an addi�onal $272 million to complete. Addi�onally, work began on dra�ing the GRIP Topic 3 applica�on. The deadline for submission is May 19th, with a target submission date of Wednesday, May 17th. The project aims to construct a transmission line from Soldotna or Nikiski to Healy, including an HVDC submarine cable and batery energy storage in the three regions. The total project cost is $793 million, and the grant request is for $396.5 million, which requires a match of $396 million. The technical volume for the applica�on was completed in the first dra�, including overall requirements, bateries write-up, HVDC Submarine cable write up and work plan, and northern and southern overhead line segments and work plan. The es�mate, project schedule, abstract, budget and budget jus�fica�on, and statement of project objec�ves for the first dra� are also in process. Other Ac�vi�es: Apart from filing grant applica�ons, we also engaged in several other suppor�ng ac�vi�es. These include: • Presented the Grid Modernization plan to the Fairbanks Chamber of Commerce. • Recorded a segment of APA’s Alaska Powerline Podcast describing our efforts at Grid modernization and to obtain both State and federal funding for this effort. • Provided routine updates to the staff of the federal delegation and the Special Assistant to the Governor on our progress and providing them with a draft letter of support. • Presented the plan to the House Energy Subcommittee. • Connected Zach Fields with Matt Perkins from Alaska Renewables regarding Zach’s desire to include some grant matching funds for renewable energy projects. • Attended the ACEP Technical Advisory group review. • Met with Doug Tansy of IBEW 1547, regarding a potential letter of support for GRIP Topic Applications. • Kept abreast of Cook Inlet CCUS (carbon capture, usage and storage) efforts. Summary: We have made significant progress in filing grant applica�ons; however, from an expecta�on se�ng perspec�ve, it is important to remember that these awards are compe��ve and, in each category, (Topics 1, 2, & 3) we will be compe�ng against between ~150 and ~200 other applica�ons na�onally with 10 to 40 awards per category depending on Topic. I want to personally thank the team of u�lity professionals as well as our consul�ng team for the ir dedica�on and perseverance, this wouldn’t be possible with them. Given the comple�on and �mely filing of two grant applica�ons and the dra�ing of the third one, we are well way to comple�ng this process. Addi�onally, their efforts to connect with stakeholders, present their plans, and obtain support showcase the team’s commitment to this work and will be cri�cal to our overall success. The June DC trip will provide further opportuni�es to further this effort.

Completed Power Tunnel Gate testing. • Dam Access Road – No change from last report. • Battle Creek Diversion – No change from last report. • Bradley Lake new building and renovations – After presenting three bid options to the O&D committee they approved using the remaining previously approved budgeted funds to purchase a Pacific Home SmartWall Package. We will realize significant savings by relocating the build site adjacent to the existing employee housing. This will allow us to take advantage of the proximity of the sewer, power, domestic and fire water systems. The existing parking area near employee housing will be utilized eliminating the need to develop a new driveway to access the site. The 90% plan review is scheduled for 8 May 2023. Package delivery is expected by 1 July 2023. Bradley Lake Operator Report Page 2 • Needle Valve Rebuild- Voith Hydro Inc. was issued a purchase order to build twelve new needle assemblies (six per unit).

May 2023 Meeting Dates: April 10, 2023 Notable Discussions and Items: 2023-2024 Water Year Inflow Forecast: Two representatives from the NOAA River Forecast Center in Anchorage attended the meeting and provided the first preliminary project inflow forecast for this summer. Both Bradley Lake watershed and the Battle Creek diversion are expected to have near normal inflows of 102% and 103% respectively. While some areas on the Kenai Peninsula have abnormally high snowpack, the Nuka Glacier metering is only reporting 87% of average. The Railbelt utilities will be using this inflow data to develop their generation plans. May – June Project work: Martin Law provided an update on the plant outage work that was scheduled to begin on April 17 and run through May 5th. HEA outlined the planned microwave communication system upgrade that is scheduled for June which will limit the ability for the Utilities to dynamically control Bradley while the work is being performed. Residence Construction Plan: Martin Law provided a cost comparison between various vendors quotes for a prefabricated home package intended to address Bradley’s needs for additional housing. Martin was provided approval to proceed with the procurement of a package from Pacific Homes which appears to provide the best value. Construction is expected to remain with the currently approved budget and be completed by this winter. Page 2 of 2 Figure 1: April 21, 2023, Bradley Lake Level Report Lake Level and Water Availability: Lake levels have continued to decline as the Utilities continue to use their available water. April 1 reports show that MEA had fully used their allocation and GVEA only had 5,130 MWh remaining. HEA and CEA had 12,518 MWH and 16,565 MWH, respectively. Committee Assignments: • No assignments from the BPMC • CEA is continuing work to address SCADA challenges to allow HEA wheeling capacity as defined in the existing Bradley agreements. Next Meeting: May 12, 2023 Current lake level Average lake level
