Feasibility and Conceptual Design !✔ Construction 2.4 Project Description Provide a brief, one-paragraph description of the proposed project. The project proposes to install, integrate, and commission a 200 kW solar/PV array energy for the islanded hybrid wind-diesel-battery-heat system for Tuntutuliak Community Services Association (TCSA), a tribally-owned community utility in Tuntutuliak, AK, which is designated as a High Energy Cost Area with a residential retail electric rate of $0.65 per kWh. The solar/PV system will utilize existing power controls, battery energy storage system to integrate the solar energy. TCSA employees are already familiar with the integration of wind+diesel+battery energy storage and have a stable, well maintained diesel power system and modern electrical distribution grid ready to accept the solar energy. The benefits of adding solar include: - Increased system reliability, due to increased renewable contributions during summer months, when wind resources are less available; - Reduced diesel maintenance and operations cost due to increased hours of diesel off operations; - Improved community resilience through additional source of energy; - The additional displacement of 2,230 gallons of diesel annually ($5.88/gallon), as well as an additional 765 hours of diesel off operations ($9.25/hour) resulting in an estimated annual reduction in operating costs in excess of $20,000; - Reduced fuel purchases; - Deferred investments in bulk fuel storage capacity; - Support for local workforce; and - Advance knowledge and understanding of integration and operation of diesel-renewable hybrid systems in the region. 2.5 Scope of Work Provide a short narrative for the scope of work detailing the tasks to be performed under this funding request. This should include work paid for by grant funds and matching funds or performed as in-kind match. The scope of work of this project is well-understood. The project team consists of experienced technologists and local operators who have actively participated in the design of this installation, but also in the integration and operation of the wind-diesel-battery-heat system over 10 years. As a result, the milestones of project scoping and contractor selection have already been completed. The solar PV will be integrated into ongoing system operations to be made available to all customers of TCSA, power purchase and heat sale agreements are not required. The project team has completed the site selection, based on permitting of the wind system. The solar array will be located near the wind project, adjacent to the abandoned runway. The area was selected to take advantage of the existing powerline and area selected by the community for development. The solar array will be supported on screw piling embedded to approximately 12 feet. Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 7 of 44 10/04/2022 The design team has included engineers and solar PV, as well as grid integration specialists. The initial phase of the project will include finalizing design and construction installation drawings. The cost estimates and construction plans are based on supply and equipment quotes, which will be finalized as funding is approved. The TCSA Board of Directors and other persons of authority for the project will undergo detailed financial analyses to develop appropriate cost, revenue, and incentive structures for the installation and eventual operation of the upgraded system. Because the panels will be installed on Tribal property – which is known not to be habitat for any vulnerable or endangered species and is not in the right-of-way or flight paths – and has undergone preliminary agency consultations and has not been designated as an historically protected area, no permitting approvals are anticipated. Financial and business plans, including financial and operational plans for end-of-life will be developed and finalized during this phase. The project will consist of 64 each, 8 panel arrays, each array made up of 525 W bifacial panels. The arrays will be oriented in the southerly direction, with individual panels tilted at an estimated 45-degree angle so as to maximize the efficiency of the system. Each 8-panel rack will be supported helical screw piles to driven depths of approximately 12 feet and bolted to the individual ground-mounted racking system. The solar/PV project will be electrically tied into the 12470 Vac electrical feeder from the wind farm through a site-based transformer, electrical disconnects, and breakers. Dispatch control will be via the existing IES/Frontier e+micro hybrid control system, which is embedded in the switchgear cabinets in the community powerplant. The control system also communicates with the each of 4, 50 kVa solar power converters, with the ability to proportionally curtail individual arrays. All components of the solar/PV system are commercially available. The demand for some components such as solar panels, power converters and electrical transformer, are currently experiencing production delays, primarily due to increased demand. It is anticipated that sufficient supplies will be available second summer barge, which will allow the materials to arrive in Tuntutuliak for construction in Summer 2024. The project will be constructed employing local labor. The project budget is based on successful completion of multiple state and federally funded energy upgrades to the TCSA system over the last decade. TCSA leadership personnel and the contractor’s staff have developed an effective and efficient working relationship, which will help to ensure timely and accurate project reporting. Environmental monitoring, permitting reports, financial reporting, final project as-builts and other documentation will be prepared to complete this project. 2.6 Previous REF Applications for the Project See Section 1.15 of the RFA for the maximum per project cumulative grant award amount Round Submitted Title of application Application #, if known Did you receive a grant?

Due to the familiarity the local workforce has with the existing system, as well as the ample experience the selected contractors have with installing and integrating renewable systems in the region, the team has a high level of confidence in the accuracy of the estimated budget. All cost estimates meet industry standards and have been verified by recent, similar prior installations in nearby communities. In the unlikely event of cost overruns, TCSA plans to do what we have always done when our power systems have been in need of upgrades, which is to apply for and secure additional funding. Our community does not have the population base or economic prosperity required to withstand rate hikes or the adoption of other methods to substantially increase revenues to the utility. We do, however, always operate “in the black” and maintain a positive credit history as well as ongoing positive relationships with funders. Our accounting systems are robust and can withstand any scrutiny, and we actively pursue opportunities for grant funding as required to upgrade and maintain our system over time. Potential sources of additional funding for this project include the USDA High Energy Costs Grant Program, the Department of Energy’s Office of Tribal Energy grant and loan programs, and possibly other state-level funding opportunities. 3.2.3 Total Project Costs Indicate the anticipated total cost by phase of the project (including all funding sources).

To the greatest degree possible, construction work/racking and panel installation will be conducted by the power plant operators and wind technicians from the local utility, and others as needed from the community. The contractor will provide several days of hands-on training for crew members from Tuntutuliak, and in turn these trained personnel will be available for consultations and to support the installation, operation, and maintenance of solar PV systems in other utilities in neighboring communities. Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 21 of 44 10/04/2022 SECTION 5 – TECHNICAL FEASIBILITY 5.1 Resource Availability 5.1.1 Assessment of Proposed Energy Resource Describe the potential extent/amount of the energy resource that is available, including average resource availability on an annual basis. For pre-construction applications, describe the resource to the extent known. For design and permitting or construction projects, please provide feasibility documents, design documents, and permitting documents (if applicable) as attachments to this application (See Section 11). Likelihood of the resource being available over the life of the project. See the “Resource Assessment” section of the appropriate Best Practice Checklist for additional guidance. Please see attached helioscope and HOMER assessments for detailed estimates of available renewable resource. 5.1.2 Alternatives to Proposed Energy Resource Describe the pros and cons of your proposed energy resource vs. other alternatives that may be available for the market to be served by your project. Due to our remote location and isolation, there are few options to heat homes in Tuntutuliak, and what options do exist are invariably expensive and logistically challenging. Trees are not available to harvest in quantities sufficient to rely on for home heat; natural gas is not an option due to our islanded location and lack of transmission and distribution infrastructure; and hydrokinetic, biofuels, biomass, geothermal, ocean/tidal, and intertie likewise are not options that are available to us.. It is largely due to this limitation of options that we have chosen to invest so heavily in wind and now seek to expand our system to incorporate the only other viable community-scale energy option, which is solar PV. Tuntutuliak residents currently use diesel generation to heat their homes. Heating fuel costs over $5.00 per gallon, and an average household uses approximately 55 gallons every 3 weeks. (Please note: The PCE report and economic models provided by AEA estimate diesel cost to be ~$3.10 per gallon, but that figure does not accurately represent the actual cost incurred by our customers for fuel oil.) According to our 2021 Power Cost Equalization Report, the average cost of electricity per kWh in Tuntutuliak was $0.65. This is almost 500% of the national average and more than three times the benchmark delineating “high energy cost communities” set forth by AEA REF regulations. In 2020, U.S. Census data indicated that the employed population in our community had increased 181% over the previous year, and yet even in these relatively prosperous times, the poverty rate in our community was 31% (a 34.5% decrease from the previous year)*. Unfortunately, much of the increase in employment in Tuntutuliak was due to short-term projects, such as the construction of a new school and a generator upgrade project, which recently completed after more than 2 years of work. In other words, it is only reasonable to infer that our poverty rate will continue to be a pressing concern in the coming years, and energy costs are likely to continue to pose a burden on our customers. Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 22 of 44 10/04/2022 This project will provide a significant contribution toward our energy needs and aid our resiliency, as well as provide a foundation upon which we can build as we continue to add to our solar PV capacity in coming years. *Source: https://datausa.io/profile/geo/tuntutuliak-ak 5.1.3 Permits Provide the following information as it may relate to permitting and how you intend to address outstanding permit issues. See the “Environmental and Permitting Risks” section of the appropriate Best Practice Checklist for additional guidance. ● List of applicable permits ● Anticipated permitting timeline ● Identify and describe potential barriers including potential permit timing issues, public opposition that may result in difficulty obtaining permits, and other permitting barriers The solar PV panels will be located on Tribal land, which is also the site of our wind turbines. The area has previously been permitted for installation of renewable energy equipment as a result of grant requirements from the USDA. No vulnerable species reside in the area. We do not anticipate any further required permitting for this project. 5.2 Project Site Describe the availability of the site and its suitability for the proposed energy system. Identify potential land ownership issues, including whether site owners have agreed to the project or how you intend to approach land ownership and access issues. See the “Site control” section of the appropriate Best Practice Checklist for additional guidance. We own the land and our Tribal authorities have approved installation of the solar panels next to the turbines. 5.3 Project Technical & Environmental Risk 5.3.1 Technical Risk Describe potential technical risks and how you would address them. ● Which tasks are expected to be most challenging? ● How will the project team reduce the risk of these tasks? ● What internal controls will be put in place to limit and deal with technical risks? See the “Common Planning Risks” section of the appropriate Best Practice Checklist for additional guidance. The technical risks of this project are minimal and well understood. Our contractors and power plant operators are very familiar with the current system, including the controls and the integration of renewables into the hybrid diesel system. One of the primary attractions of solar is that installation is technologically and logistically straight-forward. We already have the mini- excavator and other equipment required for installation, and we are well-versed in the procedures required to install the racks. Specifically, for example, we use a driver head on our mini-ex to Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 23 of 44 10/04/2022 drive pile when constructing boardwalks, and this is the same procedure our laborers will use to install the solar PV arrays. We likewise have ample experience integrating renewables into our hybrid diesel system, but one of the most compelling aspects of this project is that it will substantially increase industry knowledge of the intricacies of integrating solar into wind-diesel-battery systems. As far as we are aware, there do not currently exist any large solar PV arrays in the Yukon-Kuskokwim Delta Region, where we are located. As such, there are many questions that we simply don’t know the answers to, yet, such as the exact tilt angle that will be optimal for our latitude, best practices for maintenance and upkeep, and how best to manage the snow that will inevitably cover the panels in the winter. Through this project, we will learn how to remove the snow, how to clean the panels, and how to install the system for maximal efficiency and productivity over time. 5.3.2 Environmental Risk Explain whether the following environmental and land use issues apply, and if so which project team members will be involved and how the issues will be addressed. See the “Environmental and Permitting Risks” section of the appropriate Best Practice Checklist for additional guidance. ● Threatened or endangered species ● Habitat issues ● Wetlands and other protected areas ● Archaeological and historical resources ● Land development constraints ● Telecommunications interference ● Aviation considerations ● Visual, aesthetics impacts ● Identify and describe other potential barriers This project poses very few risks to the environment, both due to the stable and stationary nature of the solar PV panels, themselves, and because the area where they will be sited is not natural habitat for any threatened or vulnerable species. The panels will be sited either on our old airstrip runway, which is no longer utilized by aircraft, or next to the current existing wind turbines. In either case, these locations are out of the way of the flight path; we own the land; there will not be any telecommunications interference; and our community is already comfortable and familiar with the aesthetic impacts of our renewable infrastructure. Rather than being upset by its presence, our community members by-and-large support these initiatives and take pride that we are on the frontier of knowledge and technology for integrating renewables. Furthermore, from inquiries to regulatory agencies and other practical experience, we have reason to believe that permitting will not pose an impediment to the progress of our project. In the nearby community of Kongiganak, the U.S. Dept of Energy recently provided its NEPA review for a similar project and concluded that it was a Categorical Exclusion due to the minimal environmental risks of the project. Similarly, we have received regulatory approval for all of the upgrades we’ve made to our own system. We do anticipate requesting clearance from the FAA, but as noted above the installations will not be placed along a flight path, so this requirement will be only a minimal burden. Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 24 of 44 10/04/2022 5.4 Technical Feasibility of Proposed Energy System In this section you will describe and give details of the existing and proposed systems. The information for existing system will be used as the baseline the proposal is compared to and also used to make sure that proposed system can be integrated. Only complete sections applicable to your proposal. If your proposal only generates electricity, you can remove the sections for thermal (heat) generation. 5.4.1 Basic Operation of Existing Energy System Describe the basic operation of the existing energy system including: description of control system; spinning reserve needs and variability in generation (any high loads brought on quickly); and current voltage, frequency, and outage issues across system. See the “Understanding the Existing System” section of the appropriate Best Practice Checklist for additional guidance. The Tuntutuliak power system has grown in a coordinated fashion over the last 10 years. In 2021, TCSA completed the replacement of three of our diesel generators with two John Deere 6135s (334 kW each) and one John Deere 6090 (222 kW). These gensets were installed in order to maintain power plant efficiency and meet the demands of increased load growth due to the recent addition of a new school, and several new homes. At the same time the diesels were upgraded, a 270 kWh battery bank was integrated into the power plant to allow diesels off, wind only operations. TCSA is currently adding small extenders to the rotor blades on each turbine to increase energy production. Our community has a strong electrical distribution network, which was completely rebuilt to rural utility standards in 2017. The wind diesel battery hybrid power system is able to reliably operate in wind only, diesel off mode. The remote monitoring capabilities of the power plant supervisory control provide sufficient connectivity and resolution to enable regular technical support. The operation of a stable diesel grid has been a goal of the community since 2006. TCSA is applying for funding to integrate a modest community-scale solar PV array into its power system. The addition of solar is a part of progressive and low risk transition of improving the performance of its power system, with emphasis on reducing dependency on diesel fuel. TCSA has been addressing the primary barriers inhibiting the application and integration of renewables through a succession of steady improvements. Our utility has a strong organizational management in place as well as a power grid and diesel power plant that were built and designed to address concerns about construction, installation, integration, which will result in wider acceptance of hybrids into the power system (diesel+wind+solar PV+ battery energy storage). The proposed 200 kW array is located near the wind system, along the edges of the abandoned runway.

Explain how the forecast was developed and provide year by year forecasts. As appropriate, include expected changes to energy demand, peak load, seasonal variations, etc. that will affect the project. Our system has experienced an uptick in load due to a new school, which was brought online within the past year. We expect a further increase in load demand with the addition of new housing, which is currently in the planning and pre-construction phases. Our population has experienced mild to moderate growth over the past decade, from 437 in 2016 to 464 in 2021. We do not have reason to expect our population to increase substantially more in the near term. With the addition of our new, upgraded gensets and our recent addition of a battery energy storage system, we are looking forward to increased rates of efficiency and improved diesel-off functionality for the foreseeable future. 5.4.4 Proposed System Design Provide the following information for the proposed renewable energy system: ● A description of renewable energy technology specific to project location ● The total proposed capacity and a description of how the capacity was determined ● Integration plan, including upgrades needed to existing system(s) to integrate renewable energy system: Include a description of the controls, storage, secondary loads, distribution upgrades that will be included in the project ● Civil infrastructure that will be completed as part of the project—buildings, roads, etc. ● Include what backup and/or supplemental system will be in place See the “Proposed System Design” section of the appropriate Best Practice Checklist for additional guidance.

With every passing year, solar panels become more efficient and less expensive. Our community is transitioning away from diesel generation. The first steps toward this transition include the installation of wind, the integration of variable wind with batteries, advanced controls and secondary loads. This request is to provide funds to integrate solar photovoltaics. The solar produces direct current, which is converted to alternating current through power converters at the end of each string. The panels are arranged in 50 kW arrays, which are boosted to 12,470 volts and fed into the electrical distribution grid. The diesel power plant senses the solar (and wind) first as a negative load, until the diesel generator low load set point is reached. At this point, the power plant supervisory control system reconfigures the power system components to optimize renewable contribution. These operating modes may include: decrementing renewables (both wind or PV), adding secondary loads such as electric boilers and/or electric thermal storage, charging battery energy storage and switching diesel engines off. The TCSA system is equipped with a supervisory control system, and integrated battery storage to provide these options. In a standalone system, the supervisory control maintains power levels and monitors and controls the various system components to optimize system operations. The power system is designed to accept additional renewables. The power grid is capable of accepting well over 1 MW of solar at the voltages proposed. The supervisory controller can send signals to the photovoltaic power converters to curtail output should it become necessary. The system already includes a battery, which will enable diesel off operations. 5.4.3.1 Expected Capacity Factor % 5.4.5.2.

Most proposed renewable energy projects will fall under Option 1 because the new resource will not allow for diesel generation to be turned off. Some projects may allow for diesel generation to be turned off for periods of time; these projects should choose Option 2 for estimating O&M. Option 1: Diesel generation ON For projects that do not result in shutting down diesel generation there is assumed to be no impact on the base case O&M. Please indicate the estimated annual O&M cost associated with the proposed renewable project. $ Option 2: Diesel generation OFF For projects that will result in shutting down diesel generation please estimate: 1. Annual non-fuel savings of shutting off diesel generation 2. Estimated hours that diesel generation will be off per year. 3. Annual O&M costs associated with the proposed renewable project. Please see summary provided below. 5.4.7 Fuel Costs Estimate annual costs for all applicable fuel(s) needed to run the proposed system (Year 1 of operation) Please see summary provided below. Diesel (Gallons) Electricity Propane (Gallons) Coal (Tons) Wood Other Unit cost ($) Annual Units Total Annual cost ($) Annual non-fuel savings: The addition of solar is estimated to provide an additional 700 hours or more of diesel off operations with a non-fuel value estimated to be $12.00/h. This estimate is based on the capital needed to purchase and install a genset, after 45,000 of service life which is averaging $120- 150/kW. The recent replacement of two John Deere 6135 genset cost in excess of $600,000. Estimated capital replacement cost is $6.50/hour. The engine manufacturer recommends an engine overhaul at between 14,000 and 17,000 hours Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 32 of 44 10/04/2022 of operations, with overhaul costs typically cost in the range of $ 65,000. ($4.50/hr). Maintenance costs include the operator’s salary, and other consumables, including air filters, fuel filters, coolant conditioners, oil filters and oil changes. The operators are paid $25/hour. An oil change requires 4 hours, and occur every 250 hours or 10 days of operation. 2500 hours of diesel off operations, is equivalent to 10 oil changes at $100 for labor, and 15 gallons at $ 8.00/ gallon, plus filters, $18/filter. Extending oil change intervals is estimated to save , $1000/labor, plus $1380 in consumables. $.95- $1.00/hour. The maintenance costs associated with solar PV array, involve regular monthly inspections. Annual maintenance includes measurement of string voltages twice per year, cleaning, solar panels, and racking adjustments at 40 hours per year. It is estimated that the annual maintenance would involve two technicians, 8 hours per month, or 200 hours per year at $25/hour or $2500/year. 5.5 Performance and O&M Reporting For construction projects only 5.5.1 Metering Equipment Please provide a short narrative, and cost estimate, identifying the metering equipment that will be used to comply with the operations reporting requirement identified in Section 3.15 of the Request for Applications. Working with our contractor we will have electronic readings of our system. A report with a similar system in Kong is below as an example. The attachments provide an energy summary report for our system in Tuntutuliak. Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 33 of 44 10/04/2022 5.5.2 O&M reporting Please provide a short narrative about the methods that will be used to gather and store reliable operations and maintenance data, including costs, to comply with the operations reporting requirement identified in Section 3.15 of the Request for Applications TCSA has kept turbine maintenance logs throughout the operating life of our system and we will use these records as a template when preparing reports for AEA.

Include direct cost savings and other economic benefits, and how the people of Alaska will benefit from the project. Note that additional revenue sources (such as tax credits or green tags) to pay for operations and/or financing, will not be included as economic benefits of the project. Where appropriate, describe the anticipated energy cost in the community, or whatever will be affected by the project, over the life of the project. Explain how the forecast was developed and provide year-by-year forecasts The economic model used by AEA is available at https://www.akenergyauthority.org/What-We- Do/Grants-Loans/Renewable-Energy-Fund/2022-REF-Application. This economic model may be used by applicants but is not required. The final benefit/cost ratio used will be derived from the AEA model to ensure a level playing field for all applicants. If used, please submit the model with the application. The estimated $17,377 in annual cost savings from the integration of solar PV means that $17,377 will infuse the local economy each year. These savings and the resulting potential for new businesses and jobs are significant in our remote, rural community where the overall poverty rate is 31% (https://datausa.io/profile/geo/tuntutuliak-ak). This project will also help decrease dependence on diesel fuel. As we and our neighboring communities expand our renewable energy capacity, these benefits will only increase. 6.1.3 Economic Risks Discuss potential issues that could make the project uneconomic to operate and how the project team will address the issues. Factors may include: ● Low prices for diesel and/or heating oil ● Other projects developed in community Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 35 of 44 10/04/2022 ● Reductions in expected energy demand: Is there a risk of an insufficient market for energy produced over the life of the project. ● Deferred and/or inadequate facility maintenance ● Other factors Economic risks for this project are low based on proven technology, experienced contractors, and the success of similar projects in nearby communities. Diesel is not expected to go any lower than the currently- quoted $3.10. We are not near the point of installing more turbines, and our battery energy storage system is already up and running so it’s an ideal time to maximize those benefits through the addition of solar. Furthermore, solar panel technology has advanced substantially in recent years and this trend is expected to continue for the foreseeable future as global demand for the product continues to grow. Our own community load is projected to continue to increase due to upcoming additions to our housing stock, and this investment will supplement our recent installation of new generators to help prolong their useful lives through increased diesel-off hours and reduced O&M-related expenses. Our facilities are well-maintained and we will continue to preserve these investments over the long term. Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 36 of 44 10/04/2022 6.1.4 Public Benefit for Projects with Direct Private Sector Sales For projects that include direct sales of power to private sector businesses (sawmills, cruise ships, mines, etc.), please provide a brief description of the direct and indirect public benefits derived from the project as well as the private sector benefits and complete the table below. See Section 1.6 in the Request for Applications for more information. This project does not benefit any private sector businesses. All benefits will be realized by Tuntutuliak. Any power generated with locally sourced fuel means less money spent on imported diesel, decreased environmental hazard of delivery and storage of bulk fuel, and increased local job opportunities. Renewable energy resource availability (kWh per month) Estimated direct sales to private sector businesses (kWh) Revenue for displacing diesel generation for use at private sector businesses ($) Estimated sales for use by the Alaskan public (kWh) Revenue for displacing diesel generation for use by the Alaskan public ($) 6.2 Other Public Benefit Describe the non-economic public benefits to Alaskans over the lifetime of the project. For the purpose of evaluating this criterion, public benefits are those benefits that would be considered unique to a given project and not generic to any renewable resource. For example, decreased greenhouse gas emission, stable pricing of fuel source, won’t be considered under this category. Some examples of other public benefits include: ● The project will result in developing infrastructure (roads, trails, pipes, power lines, etc.) that can be used for other purposes ● The project will result in a direct long-term increase in jobs (operating, supplying fuel, etc.) ● The project will solve other problems for the community (waste disposal, food security, etc.) ● The project will generate useful information that could be used by the public in other parts of the state ● The project will promote or sustain long-term commercial economic development for the community. Reducing dependence on fossil fuels improves the sustainability of our community by: ● Reducing funds spent on fuel, which currently takes direct cash out of our small economy as all fuels must be imported; ● Reducing storage costs of fuel in our tank farm, including the maintenance and long-term replacement costs of our storage facilities; and ● Reducing the wear and tear on our diesel generators, again reducing both near- term and long-term costs to our community. Increasing our use of renewable energy will: ● Stabilize the cost of energy for our remote community. We will reap the benefits and they will continue over the long term. Without harnessing renewable energy, a remote-rural community like ours has limited options and is at the mercy of volatile fuel prices. ● Allow our community to create local jobs because dollars that otherwise would flow out Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 37 of 44 10/04/2022 of the community to pay for fuel can be utilized for community needs. Expanding the harvest of local renewable energy resources fosters a stronger economy for the village and the region. In addition to reducing purchases of diesel fuel, we will be able to use the savings to increase employment at the utility and continue to build a regional workforce for hybrid power systems. The socioeconomic benefits of this project are far-reaching and long-term. The value that locally available energy will provide to our community is immense. It will help make existing economic activities more affordable and sustainable while promoting investment from ANCSA corporations in our community. Renewable Energy Fund Round 15 Grant Application – Standard Form AEA 23046 Page 38 of 44 10/04/2022 SECTION 7 – SUSTAINABILITY Describe your plan for operating the completed project so that it will be sustainable throughout its economic life. At a minimum for construction projects, a business and operations plan should be attached and the applicant should describe how it will be implemented. See Section 11. 7.1.1 Operation and Maintenance Demonstrate the capacity to provide for the long-term operation and maintenance of the proposed project for its expected life ● Provide examples of success with similar or related long-term operations ● Describe the key personnel that will be available for operating and maintaining the infrastructure. ● Describe the training plan for existing and future employees to become proficient at operating and maintaining the proposed system. ● Describe the systems that will be used to track necessary supplies ● Describe the system will be used to ensure that scheduled maintenance is performed TCSA has a long history of successfully implementing O&M processes and procedures. We actively maintain our fleet of gensets and turbines; we have successfully integrated and managed a battery energy storage system, and we have been able to keep old and failing equipment up and running for many years and thousands of hours of run-time beyond its expected useful life. Under the close oversight and tutelage of our longtime utility manager, Mr. Carl Andrew, our 13 employees will utilize similar methods to maintain our new solar PV panels and equipment. We will actively monitor build-up of snow in the winter and clean the panels as necessary to prevent damage over time. The site will be fenced off and secure to prevent the possibility of vandalism or damage by wildlife. We will use our proven, successful means of tracking supplies to ensure that inventories are kept current, and our robust accounting practices ensure that we have the available funds necessary to cover unexpected expenses, should they arise. A similar tracking system will be implemented and utilized to guarantee that regular maintenance is performed as scheduled. Finally, our long-standing, positive relationship with our chosen contractor provides us additional security because they are always available to provide any assistance, as needed. 7.1.2 Financial Sustainability ● Describe the process used (or propose to use) to account for operational and capital costs. ● Describe how rates are determined (or will be determined). What process is required to set rates? ● Describe how you ensure that revenue is collected. ● If you will not be selling energy, explain how you will ensure that the completed project will be financially sustainable for its useful life. The proposed project will increase the amount of renewable energy captured and generated by the Tuntutuliak system and increase opportunities for diesel-off operation.
