Site work for a mixed-use development in Ouzinkie, Alaska. Completed plans call for site work for a power facility; and power facility.

In partnership with the Native Village of Ouzinkie, the Alaska Native Tribal Health Consortium (ANTHC) is soliciting proposals from design-build teams for the design and construction of ground-mounted PV arrays with an associated Battery Energy Storage System (BESS), including all improvements necessary to integrate with the community powerhouse. Transmission of power and means of communication will also need to be designed and constructed between the PV array microgrid and BESS units to the community powerhouse. Coordination with ANTHC staff will be required to support the pre-construction permitting effort. The Design-Build Team (DB Team) will be responsible for all permitting required for construction. Coordination with the local electrical utility owner, the City of Ouzinkie, and ANTHC will be required to ensure proper integration to the existing City of Ouzinkie powerhouse. B. The Tribe (Native Village of Ouzinkie) will operate the new solar array as an Independent Power Producer (IPP) and sell the power to the City of Ouzinkie. Under the proposed Independent Power Producer (IPP) model, money previously spent on fuel, will be redirected to support the water and sanitation system through a partnership between the Tribe and the City. Water and sanitation systems are not just a huge financial investment, they are critical to the health and wellbeing of the community. The proposed project will increase the sustainability and longevity of Ouzinkie's water and sewer systems, and as a result improve the health of the community. C. Substantial completion for construction and integration activities must be achieved by January 15, 2027. All other project activities (troubleshooting, optimization, etc.) are required to be completed by February 1, 2028. Location A. The City of Ouzinkie is located near Marmot Bay on the west coast of Spruce Island separated from Kodiak Island by the Ouzinkie Narrows. The City of Ouzinkie is roughly 12 air miles North of the City of Kodiak, Alaska and 245 air miles southwest of Anchorage. The village is located within the ancient homeland of the indigenous Alutiiq people, and its local Tribe is the Native Village of Ouzinkie. Ouzinkie is only accessible by air and water. Existing City of Ouzinkie Power Plant Conditions % A. The power in Ouzinkie is currently generated by a combination of diesel generators and an intermittent seasonal hydroelectric dam, most available late summer, fall and part of winter. B. The existing diesel power plant in Ouzinkie was built in 2007 and is owned and operated by the City. It consists of three John Deere generators with 45 kW, 100 kW, and 190 kW capacities running at three phase; 1800 RPM; 60 Hz; 277/480 voltage; 0.8 Power Factor. C. The hydroelectric dam has a turbine with 125kW capacity. It has historically supplied roughly half of total power production, and in the last two years typically runs between 35 to 50 kW. The hydroelectric generator was offline from 2021-2023 until after repairs to the penstock, and is currently offline awaiting repairs due to be completed in April 2025. D. The Alaska Energy Authority has recently provided funding to upgrade Ouzinkie power plant. These upgrades include: 1. Switchgear and easYgen diesel generator controls were upgraded in 2023 to be renewables ready. 2. Hydro turbine plant currently runs DSLC controls and is funded to be replaced with easYgen in Spring 2025. 3. The existing power plant SCADA system is Ignition 8.1 by Inductive Automation E. Ouzinkie has the following load profiles, based on the 2023 PCE report: 1. Average load: 79 kW 2. Annual Electricity Generated: 690,924 kWh 3. Annual Fuel Consumption: 53,801 gallons 1.4 Site Considerations A. The solar array will be installed on the historic and decommissioned Ouzinkie airport airstrip and is expected to occupy approximately 1.5 acres. The full airstrip is approximately 1000 feet long by 100 feet across. The Selected Design-Build Team is responsible for all work necessary to delivering a well integrated, complete and functional solar PV and Battery Energy Storage System. The project generally includes the following items: A. Design, procurement, and installation of a minimum of 160 kW solar PV array microgrid. 1. Solar PV modules, Solar PV inverters, and all required appurtenances. 2. Solar racking system, and foundation system, such as ballasted, ground screwed, etc. 3. Perimeter fencing with gate access B. Design, procurement, and installation of a minimum of 240 kW/210 kWh BESS system. 1. A complete and operable BESS, that is designed for grid-forming operation and integrated with the existing power system. The BESS shall include a climate-controlled enclosure and all appurtenances required for its operation and interconnection, including, but not limited to: battery cells and racking, wiring, battery management system, interior and exterior lighting, foundation, climate controls, fire suppression, grid-forming inverter(s), labels and safety markings. 2. Engineered BESS foundation/pad C. Design, procurement, and installation of Balance of System components, including electrical power distribution infrastructure between solar PV array microgrid, BESS, and City of Ouzinkie Power Plant. These items include but are not limited to: 1. All required conductors and conduit sized in accordance with best practices and applicable codes. 2. All pull boxes and junction boxes in accordance with best practices and applicable codes. 3. Transformer pads. 4. Three-phase transmission, including transformers, from the PV site to The BESS/Power Plant, either overhead or buried. 5. Three-phase connection, including transformers between the BESS and power plant. 6. Metered station service for the BESS. 7. All cable tray, wiring, AC equipment, and consumables required for an installation that meets Code and manufacturer warranty requirements. D. Design, procurement, and installation of any modifications to existing City of Ouzinkie Power Plant and power system to accept and utilize power produced by newly installed infrastructure to meet project objectives. These items include but are not limited to: 1. Microgrid Controller that will interface with the existing power plant PLC and SCADA system. 2. A dedicated hard cable communication link between the PV array and the existing power plant. 3. A dedicated hard cable communication link between the BESS and the existing power plant. 4. Interconnection for the PV array power into the existing City of Ouzinkie power plant and/or electrical grid. 5. Interconnection of the BESS into the City of Ouzinkie power plant. Page 4 of 16 6.
