Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 2 of 13 10/8/2008 SECTION 2 – PROJECT SUMMARY Provide a brief 1-2 page overview of your project. 2.1 PROJECT TYPE Describe the type of project you are proposing, (Reconnaissance; Resource Assessment/ Feasibility Analysis/Conceptual Design; Final Design and Permitting; and/or Construction) as well as the kind of renewable energy you intend to use. Refer to Section 1.5 of RFA. The Alaska Village Electric Cooperative (AVEC) is proposing to conduct a feasibility analysis and conceptual design for wind power to supplement AVEC’s diesel powered generation in New Stuyahok. 2.2 PROJECT DESCRIPTION Provide a one paragraph description of your project. At a minimum include the project location, communities to be served, and who will be involved in the grant project. A meterological (met) tower installed in New Stuyahok between 2003 and 2005 found that winds were class 3 (fair to good); however, placement of the met tower was hindered by the active runway at the time (location new airport has now been constructed out of town), and it is expected that the wind resource could be better. Before going forward with the final design and construction of wind turbines, AVEC would like to better determine the wind potential in the community. The work would involve obtaining a letter of non‐objection for placement of the wind tower and geotechnical fieldwork, permitting, purchasing, transporting, and installing a met tower, studying the wind resource for one year, and conducting a geotechnical investigation to determine the soil conditions and needed engineering at the site. A conceptual design will be created based on the outcome of the met tower recordings and geotechnical investigation. Wind generators placed at the old airport could reduce the annual fuel consumption of the diesel generators, thus reducing the cost of electricity within New Stuyahok, as well as reducing the overall volume of fuel that is handled within the community and risks associated with handling fuel. The City of New Stuyahok, the New Stuyahok Tribal Council, Stuyahok Limited, and the Southwest Regional School District (SWSD) have expressed support for the project. The New Stuyahok Comprehensive Plan (October 2005), states that the high cost of fuel and energy is one of the major regional challenges in the area and that to respond to this challenge the community and region must promote lower energy costs. 2.3 PROJECT BUDGET OVERVIEW Briefly discuss the amount of funds needed, the anticipated sources of funds, and the nature and source of other contributions to the project. Include a project cost summary that includes an estimated total cost through construction. The total project cost for the project is $123,800 of which $117,610 is requested in grant funds. The remaining $6,190 will be matched in cash by AVEC. A detail of the costs is: Task Total Obtain Site Control/Right of Entry/Permits $7,000 Purchase Met Tower $12,100 Ship Met Tower $3,000 Erect, Monitor, and Dismantle Met Tower $20,700 Complete Geotech Work $65,000 Complete Wind Resource Report $6,000 Complete Conceptual Design $10,000 Total $123,800 Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 3 of 13 10/8/2008 The total project costs through construction depend on the outcome of the wind resource study and geotechnical report; however, an estimate can be made: Estimated Final Design and Permitting: $210,000. Estimated Construction and Commissioning: $4,103,000. Estimated Project Total (including this phase): $4,436,800. 2.4 PROJECT BENEFIT Briefly discuss the financial benefits that will result from this project, including an estimate of economic benefits (such as reduced fuel costs) and a description of other benefits to the Alaskan public. The primary financial benefit from this project would be reduced fuel costs to the people of New Stuyahok. The possible displacement of diesel fuel used for village power generation in New Stuyahok was over 87,960 gallons in 2007 at a cost of over $266,826. If the conditions are suitable and wind turbines are installed, the residents of New Stuyahok would benefit from reduced power costs. Other Benefits to the Alaskan Public: The anticipated benefits of installation of the wind turbines would be reducing the negative impact of the cost of energy by providing a renewable energy alternative. This project could help stabilize energy costs and provide long‐term socio‐economic benefits to village households. Locally produced, affordable energy will empower community residents and could help avert rural to urban migration. This project would have many environmental benefits resulting from a reduction of hydrocarbon use. These benefits include: Reduced potential for fuel spills or contamination during transport, storage, or use (thus protecting vital water and subsistence food sources) Improved air quality Decreased contribution to global climate change from fossil fuel use Decreased coastal erosion due to climate change 2.5 PROJECT COST AND BENEFIT SUMARY Include a summary of your project’s total costs and benefits below. 2.5.1 Total Project Cost (Including estimates through construction.) $4,436,800. 2.5.2 Grant Funds Requested in this application. $ 117,610. 2.5.3 Other Funds to be provided (Project match) $ 6,190 2.5.4 Total Grant Costs (sum of 2.5.2 and 2.5.3) $ 123,800 2.5.5 Estimated Benefit (Savings) To be determined 2.5.6 Public Benefit (If you can calculate the benefit in terms of dollars please provide that number here and explain how you calculated that number in your application.)

Obtain Site Control/Right of Entry/Permits: AVEC proposes to get as much completed in the first year (2009) of this project as possible. AVEC would work with the current land owner to obtain permission for placing the met tower and conducting geotechnical work immediately following AEA’s authorization to proceed. AVEC would also immediately seek approvals from permitting agencies. Erect Met Tower: The earlier the met tower is collecting data, the earlier AVEC will have the wind resource data to ascertain the suitability of use this renewable resource. AVEC proposes to erect the tower immediately following approvals from the landowner and permitting agencies. Complete Geotech Field Work: In order to understand site conditions early in the process, geotechnical field work would be conducted immediately following gaining approvals from the land owner and permitting agencies. The geotechnical report would be completed 60 days later. Complete Wind Resource Report: The met tower would be monitored to ensure that the wind tower is functioning properly and that bird diverters are intact. Wind data would be collected for one year. Complete Conceptual Design: It is likely that preliminary data from the met tower could allow for conceptual design to be drafted. The final concept design would be completed as soon as possible following completion of the Wind Resource Report. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 5 of 13 10/8/2008 3.4 Project Resources Describe the personnel, contractors, equipment, and services you will use to accomplish the project. Include any partnerships or commitments with other entities you have or anticipate will be needed to complete your project. Describe any existing contracts and the selection process you may use for major equipment purchases or contracts. Include brief resumes and references for known, key personnel, contractors, and suppliers as an attachment to your application. AVEC will use a project management approach that has been used to successfully install met towers throughout rural Alaska: A team of AVEC staff and external consultants. AVEC staff and their role on this project includes: Meera Kohler, President and Chief Executive Officer, will act as Project Executive and will maintain ultimate authority programmatically and financially. Brent Petrie, manager of the community development group, will be the project manager. Together with his group, Brent will provide coordination of the installation of the met tower, geotechnical work, and conceptual design. The group’s resources include a project coordinator, contracts clerk, accountant, engineer, and a community liaison. Debbie Bullock, manager of administrative services will provide support in accounting, payables, financial reporting, and capitalization of assets in accordance with AEA guidelines. An AVEC project manager will lead this project. The project manager will be responsible for: Obtaining site control/access and permits for the installation of the met tower and geotechnical work Selecting, coordinating, and managing the engineering consultant Communicating with New Stuyahok residents to ensure that the community is informed Contractors for this project would include: Wind Resource Consultant. AVEC will employ a wind resource consultant who will: o Supervise the installation of the met tower o Consult on the operation and maintenance of the tower o Draft the wind resource report Engineering consultant. AVEC will employ an engineering consultant who will: o Select, coordinate, and manage the geotechnical contractor o Create the wind turbine facility conceptual design Selection Process for Contractors: The engineering consultant selection will be based upon technical competencies, past performance, written proposal quality, cost, and general consensus from the technical steering committee. The selection of the consultant will occur in strict conformity with corporate procurement policies, conformance with OMB circulars, and DCAA principles. 3.5 Project Communications Discuss how you plan to monitor the project and keep the Authority informed of the status. AVEC will assign a project manager to the project. The project manager will work closely with the construction manager to ensure adherence to the project schedule and budget. Weekly and monthly project coordination meetings will be held with the project team to track progress and address issues as they arise. The project manager will provide quarterly reports to AVEC for finalization and submission to the AEA. 3.6 Project Risk Discuss potential problems and how you would address them. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 6 of 13 10/8/2008 Because the City of New Stuyahok, Stuyahok Limited (village corporation), and the Native Village of New Stuyahok have been involved in the planning of this project and because this project could provide relief for high power costs, the community is very supportive of this project. Site Control/Access. Currently the old airport site belongs to Alaska Department of Transportation and Public Facilities (DOT&PF). AVEC representatives recently met with DOT&PF to discuss this project. DOT&PF stated that there were no plans to give the community the old airport property; however, the Department was very interested in the wind project and supporting the State of Alaska in finding alternative energy solutions. AVEC will continue to work with the DOT&PF to obtain approval to place the met tower on the old runway and to conduct geotechnical work at the old airport. Weather. Weather could delay geotechnical field work; however, an experienced consultant, familiar with Alaskan weather conditions, would be selected. It unlikely that a delay in the total project schedule would occur if the field work is delayed. The met tower would be installed to handle the New Stuyahok’s winter weather conditions. The met tower would be monitored to ensure the met tower is up and functioning. Logistics. Transport of the met tower to New Stuyhok would not be difficult, provided the tower is ready to be shipped before freeze up and the last barge. The tower could also be flown in, if needed. SECTION 4 – PROJECT DESCRIPTION AND TASKS Tell us what the project is and how you will meet the requirements outlined in Section 2 of the RFA. The level of information will vary according to phase of the project you propose to undertake with grant funds. If you are applying for grant funding for more than one phase of a project provide a plan and grant budget for completion of each phase. If some work has already been completed on your project and you are requesting funding for an advanced phase, submit information sufficient to demonstrate that the preceding phases are satisfied and funding for an advanced phase is warranted. 4.1 Proposed Energy Resource Describe the potential extent/amount of the energy resource that is available. Discuss 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. Based on a study completed by V3 Energy, LLC in 2008, New Stuyahok has fair to good (Class 3) potential for wind power development. When the study was completed, the airport limited the location of the wind meterological tower. Since then the airport has be relocated farther out of town and V3 Energy suspects that the wind resource could be better by placing the turbines at the Old Airport Site. More information is needed to determine whether wind energy is the best alternative energy resource for the community. Solar power from photovoltaic solar arrays is a potential alternative, but has higher capital cost and lower resource availability than wind in New Stuyahok. An in‐stream hydrokinetic turbine, similar to what was tested in Ruby, Alaska by the Yukon River Inter‐ Tribal Council in the summer of 2008, may be an energy option in the future, but this technology is in the planning and development stage. 4.2 Existing Energy System 4.2.1 Basic configuration of Existing Energy System Briefly discuss the basic configuration of the existing energy system. Include information about the number, size, age, efficiency, and type of generation. New Stuyahok was energized in 1972. The power plant includes three generator sets with the combined capacity of 956 kW. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 7 of 13 10/8/2008 Generator details are: Type Capacity Age (years) CMS 499 5 DD 207 14 CMS 250 19 The peak demand reported in the 2007 at the power plant is 265 kW. The overall average plant load in 2007 was 143 kW per hour. The plant generated 13.67 kWh for each gallon of fuel consumed in 2007. Design and permitting of a new power plant, along with new fuel storage facilities and a dispensing area, will be completed in December 2008. A new power plant has been designed and will be constructed concurrently with the wind turbines. 4.2.2 Existing Energy Resources Used Briefly discuss your understanding of the existing energy resources. Include a brief discussion of any impact the project may have on existing energy infrastructure and resources. New Stuyhok uses diesel and heating oil as the primary energy resources. Annual diesel fuel consumption for power generation in New Stuyhok in 2007 was 87,967 gallons. Installation of wind turbines in the community would decrease the amount of diesel fuel used for power generation. 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. New Stuyahok is located on the Nushagak River, 52 miles northeast of Dillingham, about 12 miles upriver from Ekwok and 50 miles downriver from Koliganek. Average summer temperatures range from 37 to 66° F; winter temperatures average 4 to 30° F. The village is categorized as a “distressed” community by the Denali Commission; the median household income is $26,042—less than half of the State’s median household income of $59,036. The electricity consumption in New Stuyahok in FY2007 was 1,206,029 kWh. The load of is highest during the winter months, with the bulk of electricity consumed by residences and the school. AVEC expects the addition of wind turbines to the electric generation system to reduce the amount of diesel fuel used for power generation and for heating. New Stuyahok is an isolated village, relying on air transportation for delivery of medical goods and transport of sick or injured individuals, or mothers nearing childbirth. Reliable electric service is essential to maintaining vital navigation aids for the safe operation of aircraft. Runway lights, automated weather observation stations, VASI lights, DME’s and VOR’s are all powered by electricity. Emergency medical service is provided in a health clinic by a health aide. Medical problems and emergencies must be relayed by telephone or by some other communication means for outside assistance. Operation of the telephone system requires electricity. Reliable telephone service requires reliable electric service. In New Stuyahok, water is obtained from a well and is treated. The majority of the community, facilities, and the school are connected to a piped water and sewer system. Reliable electric service is required for the continuous operation of the water and wastewater systems and to prevent freezing of the systems which will cause extensive damage and interruptions in service. Like all of Alaska, New Stuyahok is subject to long periods of darkness. Reliable electric service is essential for the operation of home lighting, streetlights, and security lighting. Outside lighting ensures the safety of children. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 8 of 13 10/8/2008 According to the New Stuyahok Comprehensive Plan, residents of New Stuyahok rely on subsistence resources gathered from the Nushagak‐Mulchatna watershed. Subsistence food is gathered and harvested and stored in refrigerators and freezers. A new community freezer facility was under construction by the Tribe in October 2008. Refrigeration is essential for the extended storage of perishable food stuffs. Reliable electric service is essential for proper freeze storage of food. Sources: U.S. Census Bureau, Census 2000; Statistical Report of the Power Cost Equalization Program, Fiscal Year 2007, Alaska Energy Authority 4.3 Proposed System Include information necessary to describe the system you are intending to develop and address potential system design, land ownership, permits, and environmental issues. 4.3.1 System Design Provide the following information for the proposed renewable energy system: A description of renewable energy technology specific to project location Optimum installed capacity Anticipated capacity factor Anticipated annual generation Anticipated barriers Basic integration concept Delivery methods Alternative Energy Technology. AVEC plans to conduct a Feasibility Analysis, Resources Assessment, and Conceptual Design to assess the possibility of using wind power in New Stuyahok. If the wind resource proves suitable, wind turbines would be installed. Optimum installed capacity/Anticipated capacity factor/Anticipated annual generation. The purpose of this work is to gather background information to plan a future alternative energy facility. The capacity is unknown at this time. Anticipated barriers. The potential barriers to success of this project include logistics, site access and weather. The barriers are minor and do not pose a threat to the completion of this project, tasks which must be accomplished. Basic integration concept/Delivery methods. Conceptual design, to be completed as a part of this project, would detail how power from a wind turbine would be integrated and delivered into the existing system. If the wind is suitable for development, the turbines will interconnect with the power plant. It is expected that wind‐generated electrical energy will be delivered via the existing electrical distribution. 4.3.2 Land Ownership 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. The proposed location of the wind turbines is at and adjacent to the old airport. The land is currently owned by the Alaska Department of Transportation and Public Facilities (DOT&PF) and New Stuyahok Limited. AVEC recently met with DOT&PF to determine the status of the old airport land. DOT&PF stated that they had not made any plans to give or sell the community the property. The Department was very interested in the wind project and stated that they would be willing to discuss placement of turbines at the airport site (See Tab 6‐Supplemental Materials). AVEC will continue to discuss airport land issues with DOT&PF‐starting with obtaining permission to place the met tower and conduct geotechnical work. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 9 of 13 10/8/2008 In addition, the City of New Stuyahok and Stuyahok Limited have signed a Memorandum of Agreement and Joint Resolution stating that if either entity receives title to the old airport land the appropriate party will make the site available to AVEC by deed or long term lease for the construction of wind turbines (See Tab 6‐Supplemental Materials). Representatives from Stuyahok Limited have stated that the corporation would be willing to work with AVEC to place turbines on their land, if this study finds that wind is a feasible resource in New Stuyahok. 4.3.3 Permits Provide the following information as it may relate to permitting and how you intend to address outstanding permit issues. List of applicable permits Anticipated permitting timeline Identify and discussion of potential barriers The U.S. Fish and Wildlife Service concurred that the placement of wind turbines will have no affect on threatened or endangered species (See Tab 6‐Supplemental Materials). An U.S. Army Corps of Engineers (Corps) Wetlands Permit may be needed for the geotechnical work. The Corps has a “Nationwide Permit” for survey work, including geotech field work. This permit usually takes no more than three weeks to obtain. (Because a Corps’ Nationwide Permit exists, a State of Alaska Department of Natural Resources, Division of Coastal and Ocean Management Coastal Project Questionnaire and Enforceable Policies Consistency Determination is not needed.) 4.3.4 Environmental Address whether the following environmental and land use issues apply, and if so how they will be addressed: 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 discuss other potential barriers Threatened or Endangered species. The U.S. Fish and Wildlife Service concurred that the placement of wind turbines (and therefore a met tower) will have no affect on threatened or endangered species (See Tab 6‐Supplemental Materials). The met tower would be marked to help birds to avoid collisions. During a meeting regarding this project (October 16, 2008), the U.S. Fish and Wildlife did not express special concerns regarding impacts to birds by the wind turbines. Construction would be timed to avoid impacts to migratory birds in compliance with the Migratory Bird Treaty Act. Habitat issues. New Stuyahok is not within any State refuges, sanctuaries, or critical habitat areas, federal refuges or wilderness areas, or national parks. In addition, New Stuyahok is not within or near any critical habitat for threatened or endangered species. Wetlands and other protected areas. Depending on the outcome of this feasibility study, wind turbines could be placed in wetland locations. An U.S. Army Corps of Engineers’ wetlands permit would be needed. Archaeological and historical resources. The met tower would be placed and geotechnical work would be conducted at the old airport. Compliance with the National Historic Preservation Act with the State Historic Preservation Officer would be conducted if the outcome of this study finds that wind power is feasible in New Stuyahok. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 10 of 13 10/8/2008 Land development constraints. The City of New Stuyahok and Stuyahok Limited have stated that the Old Airport is the best location for the wind turbines. Although the land currently belongs to the DOT&PF, the Department has stated that they would be willing to work with AVEC to look at the wind resource in more detail. The City and Corporation have signed a MOA agreeing to deed or lease the old airport land to AVEC for the wind turbines, if DOT&PF give them the land (Tab 6‐Supplemental Materials). Aviation considerations. The met tower and geotechnical work would be located approximately 2.5 miles from the active airport and outside any important operational aircraft area. Visual, aesthetics impacts. Although the met tower and geotechnical work is proposed on a hill that would be visible from much of the community, residents has stated that the Old Airport is the best location for the turbines, and therefore this study. 4.4 Proposed New System Costs (Total Estimated Costs and proposed Revenues) The level of cost information provided will vary according to the phase of funding requested and any previous work the applicant may have done on the project. Applicants must reference the source of their cost data. For example: Applicants Records or Analysis, Industry Standards, Consultant or Manufacturer’s estimates. 4.4.1 Project Development Cost Provide detailed project cost information based on your current knowledge and understanding of the project. Cost information should include the following: Total anticipated project cost, and cost for this phase Requested grant funding Applicant matching funds – loans, capital contributions, in-kind Identification of other funding sources Projected capital cost of proposed renewable energy system Projected development cost of proposed renewable energy system AVEC plans to conduct a Feasibility Analysis, Resources Assessment, and Conceptual Design to assess the possibility of using wind power in New Stuyahok. This work will cost $123,800. AVEC requests $117,610 from AEA. AVEC will provide $6,190 as an in‐kind contribution. If the wind resource proves suitable, the next phase of this project would be Final Design and Permitting (Phase III). Although it is difficult to determine without an assessment of the resource and what type, size, and number of turbine would be needed, AVEC expects that Final Design and Permitting would cost $210,000. AVEC would provide a 5% in‐kind match ($10,500). It is possible that the funding for this work could come from the AEA Renewable Energy Program, the Denali Commission, a USDA Rural Utility Service program, or another grant program. The final phase of this project would be Construction and Commissioning (Phase IV). AVEC estimates that this phase could cost $4,421,700, assuming installation of three Northwind 100 wind turbines. AVEC would provide a 10% cash match ($410,300). It is possible that the funding for this work could come from the AEA Renewable Energy Program, the Denali Commission, a USDA Rural Utility Service program, or another grant program. 4.4.2 Project Operating and Maintenance Costs Include anticipated O&M costs for new facilities constructed and how these would be funded by the applicant. Total anticipated project cost for this phase Requested grant funding The met tower would require monthly monitoring and data management. It is expected that this will cost $700. The cost will be funded by this grant award. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 11 of 13 10/8/2008 4.4.3 Power Purchase/Sale The power purchase/sale information should include the following: Identification of potential power buyer(s)/customer(s) Potential power purchase/sales price - at a minimum indicate a price range Proposed rate of return from grant-funded project AVEC, the existing electric utility serving New Stuyahok, is a member owned cooperative electric utility and typically owns and maintains the generation, fuel storage, and distribution facilities in the villages it serves. New Stuyahok includes 99 households and community facilities, including a health clinic, city office, tribal council office, and water treatment plant, which purchase power from AVEC. At this point in project development, the potential power price and rate of return on the project is unknown. 4.4.4 Cost Worksheet Complete the cost worksheet form which provides summary information that will be considered in evaluating the project. Please see attachment. 4.4.5 Business Plan Discuss your plan for operating the completed project so that it will be sustainable. Include at a minimum proposed business structure(s) and concepts that may be considered. The New Stuyahok Bulk Fuel Facility Business Operating Plan (August 2007) identifies the operation, maintenance, and sustainability of the New Stuyahok bulk fuel facilities. The wind turbines, if feasible, will be incorporated into this plan. In summary, the plan will specify that: The wind turbines will be incorporated into AVEC’s power plant operation. Local plant operators provide daily servicing. AVEC technicians provide periodic preventative or corrective maintenance and are supported by AVEC headquarters staff, purchasing, and warehousing. 4.4.6 Analysis and Recommendations Provide information about the economic analysis and the proposed project. Discuss your recommendation for additional project development work. The wind turbines and control systems, if proved feasible, will be fully incorporated into AVEC’s power plant operations; therefore, the wind turbines will be treated as generating equipment, just like the generator sets. Maintenance schedules would be routinely developed and managed. The result would be improved reliability from the existence of additional generating sources and reduced fuel consumption from the use of wind. Possible community growth, along with significant increases in the delivered cost of diesel fuel, makes this local resource a timely candidate for evaluation for a feasibility analysis and conceptual design. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 12 of 13 10/8/2008 SECTION 5– PROJECT BENEFIT Explain the economic and public benefits of your project. Include direct cost savings, and how the people of Alaska will benefit from the project. The benefits information should include the following: Potential annual fuel displacement (gal and $) over the lifetime of the evaluated renewable energy project Anticipated annual revenue (based on i.e. a Proposed Power Purchase Agreement price, RCA tariff, or avoided cost of ownership) Potential additional annual incentives (i.e. tax credits) Potential additional annual revenue streams (i.e. green tag sales or other renewable energy subsidies or programs that might be available) Discuss the non-economic public benefits to Alaskans over the lifetime of the project Potential Fuel Displacement: The possible displacement of diesel fuel used for village power generation in New Stuyahok currently totals over 87,967 gallons per year at a cost of over $418,723. Much greater amounts of displaced fuel are possible if electric heating is used to displace heating fuel. The exact amount of fuel displacement at this point in the project is not known. Potential annual fuel displacement: In 2008, AVEC spent an average of $4.76 per gallon for the fuel for power generation. If the wind resource proves suitable and turbines are installed, the residents of New Stuyahok would benefit from decreased fuel use; however, at this point in the project the amount of fuel displacement is unknown Anticipated annual revenue/Potential additional annual incentives/Potential additional annual revenue streams. Because this project is in the feasibility and concept design stage, revenue and incentives are unknown. Non‐economic public benefits. If wind energy is feasible in New Stuyahok and wind turbines are installed in the community, energy costs could stabilize and long‐term socio‐economic benefits could result. Wind power would have many environmental benefits resulting from a reduction of hydrocarbon use, including reduced potential for fuel spills or contamination, improved air quality, and decreased contribution to global climate change from fossil fuel use. SECTION 6 – GRANT BUDGET Tell us how much your total project costs. Include any investments to date and funding sources, how much is requested in grant funds, and additional investments you will make as an applicant. Include an estimate of budget costs by tasks using the form - GrantBudget.xls The total project costs through construction depend on the outcome of the wind resource study and geotechnical report as well as construction year and market conditions; however, an estimate can be made: Estimated Final Design and Permitting: $210,000. Estimated Construction and Commissioning: $4,103,000. Estimated Project Total (including this phase): $4,436,800. Over the past 5 years, AVEC completed a wind resource assessment (Tab 6‐Supplemental Materials). This work was completed together with studying upgrades to the bulk fuel tank farm and power plant and was funded by AVEC, AEA, and the Denali Commission. It is estimated that $20,000 was invested in equipment delivery and installation, and wind monitoring at the met tower site that was available at the time. The site that was available was located about half way down a north facing hill because the runway site that is now proposed for the turbine site was in active use the new airport was constructed. The earlier monitoring data indicated strong turbulence which may be due to the specifics of the met tower location, which was one of the first deployments under a State assisted program. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 13 of 13 10/8/2008 Near the old runway site, there are trees with limbs on one side (referred to as flagging), which would indicate strong directional winds. Now that the old runway is vacated, our consultant recommends additional monitoring to see if a superior resource exists at the proposed turbine site and to see if turbulence there is less than initially shown and more acceptable. The total project cost for the project is $123,800 of which $117,610 is requested in grant funds. The remaining $6,190 will be matched in cash by AVEC.

Note however that the test site appeared to be adversely affected by the presence of nearby trees with respect to measured turbulence. Data Synopsis Wind power class Class 3 – Fair Wind speed annual average (30 meters) 5.46 m/s Maximum wind speed measured 33.6 m/s, November 2004 Mean wind power density (30 meters) 232 W/m2 (measured) Weibull distribution parameters k = 1.76, c = 6.29 m/s Roughness Class 4.39 m (suburban) Power law exponent 0.382 (high wind shear) Turbulence Intensity 0.151 (moderate to high) Data start date October 10, 2003 Data end date July 7, 2005 Community Profile Current Population:472 (2005 State Demographer est.) Pronunciation/Other Names:(STEW-yuh-hawk) Incorporation Type:2nd Class City Borough Located In:Unorganized School District:Southwest Region Schools Regional Native Corporation:Bristol Bay Native Corporation Location: New Stuyahok is located on the Nushagak River, about 12 miles upriver from Ekwok and 52 miles northeast of Dillingham. The village has been constructed at two elevations -- one 25 feet above river level, and one about 40 feet above river level. It lies at approximately 59.452780° North Latitude and - 157.311940° West Longitude. (Sec. 29, T008S, R047W, Seward Meridian.) New Stuyahok is located in the Bristol Bay Recording District. The area encompasses 32.6 sq. miles of land and 2.0 sq. miles of water. History: The present location is the third site that villagers can remember. The village moved downriver to the Mulchatna area from the "Old Village" in 1918. During the 1920s and 30s, the village was engaged in herding reindeer for the U.S. government. However, by 1942 the herd had dwindled to nothing; the village had been subjected to flooding; and the site was too far inland even to receive barge service. So in 1942, the village moved downriver again to its present location. Stuyahok appropriately means "going downriver place." The first school was built in 1961. A post office was also established during that year. An airstrip was built soon thereafter, and the 1960s saw a 40% increase in the village population. The City was incorporated in 1972. Culture: New Stuyahok is a southern Yup'ik Eskimo village with Russian Orthodox influences. Residents practice V3 Energy, LLC 2 of 21 New Stuyahok, Alaska Wind Resource Report a fishing and subsistence lifestyle. Economy: The primary economic base in New Stuyahok is the salmon fishery; forty-three residents hold commercial fishing permits. Many trap as well. The entire community relies upon subsistence foods. Subsistence items are often traded between communities. Salmon, moose, caribou, rabbit, ptarmigan, duck and geese are the primary sources of meat. Facilities: Water is derived from a well and is treated. A new well is under development. The majority of the community (94 homes), facilities and the school are connected to a piped water and sewer system installed in 1971 and have complete plumbing. Some residents use individual wells and septic tanks; six homes are without complete plumbing. A Master Plan has been funded. Transportation: Air transport is most frequently used to reach the community. Regular and charter flights are available from Dillingham. The State-owned gravel airstrip is 1,800' long by 50' wide and lighted. It is located on a hilltop; windy conditions often preclude landing. The community has requested funds for construction of a crosswind landing strip. There are no docking facilities. Goods are lightered on a regular basis during the summer. Skiffs, ATVs and snowmachines are prevalent forms of local transportation. Climate: New Stuyahok is located in a climatic transition zone. The primary influence is maritime, although a continental climate affects the weather. Average summer temperatures range from 37 to 66; winter temperatures average 4 to 30. Annual precipitation ranges from 20 to 35 inches. Fog and low clouds are common during the summer; strong winds often preclude access during the winter. The River is ice-free from June through mid-November.

V3 Energy, LLC 6 of 21 New Stuyahok, Alaska Wind Resource Report Time Series of Wind Speed Averages As expected, higher winds occur during the winter and spring months of October through April while lower winds occur during the summer and autumn months, although the seasonal differential in New Stuyahok is more pronounced than observed in coastal villages. V3 Energy, LLC 7 of 21 New Stuyahok, Alaska Wind Resource Report Wind Shear Profile The power law exponent was calculated at 0.382, indicating high wind shear at the New Stuyahok test site, as noted in the second graph below. There is a possibility though that the presence of trees near the meteorological tower test site may have affected the 20 meter anemometer more significantly than the 30 m anemometer, resulting in a higher shear power law exponent than one might expect. In the village of Koliganek, upriver from New Stuyahok, a more open wind test site measured a wind shear of power law exponent of 0.227, which although moderately high itself, is more likely representative of New Stuyahok than the measured exponent of 0.382. If in fact the real shear exponent in New Stuyahok is lower than measured, the 50 meter wind power density listed in the data synopsis on page one of this report will be biased high and a 50 meter wind power density of approximately 375 to 400 W/m2 is likely more realistic. The practical application of this data is that a higher turbine tower height is desirable as there will be a substantial gain in wind speed/power recovery with additional height. A tower height/power recovery/ construction cost tradeoff study is advisable. V3 Energy, LLC 8 of 21 New Stuyahok, Alaska Wind Resource Report V3 Energy, LLC 9 of 21 New Stuyahok, Alaska Wind Resource Report Probability Distribution Function The probability distribution function provides a visual indication of measured wind speeds in one meter per second “bins”. Note that most wind turbines do not begin to generate power until the wind speed at hub height reaches 4 m/s. The black line in the graph is a best fit Weibull distribution. At the 30 meter level, measured Weibull parameters are k = 1.76 (indicates a moderate distribution of wind speeds) and c = 6.29 (scale factor). The PDF information is shown visually in another manner in the second graph, the Cumulative Distribution Function. V3 Energy, LLC 10 of 21 New Stuyahok, Alaska Wind Resource Report V3 Energy, LLC 11 of 21 New Stuyahok, Alaska Wind Resource Report Wind Roses New Stuyahok winds are highly directional with, as the wind frequency rose indicates, north- northwest (NNW) and east-northeast (ENE) winds predominating. This observation is reinforced with reference to the power density rose below. The power producing winds in New Stuyahok are nearly exclusively NNW and ENE. The practical application of this information is that site(s) should be selected with relatively few obstructions from west to north to southeast to minimize wind turbulence at the turbines. Note also that a wind threshold of 4 m/s was selected for the definition of calm winds. This wind speed represents the cut-in wind speed of most wind turbines. By this definition, Naknek experienced 36 percent calm conditions during the measurement period (see wind frequency rose below).

V3 Energy, LLC 14 of 21 New Stuyahok, Alaska Wind Resource Report IEC Turbulence Intensity Standards The turbulence intensities at 30 meters at the New Stuyahok project test site do not meet International Electrotechnical Commission (IEC) Category A standards in the northeast to southeast quadrant and IEC Category A in the southeast to southwest quadrant. This is less important in the SE to SW quadrant as the wind rarely blows from this direction, but is more so important in the NE to SE quadrant as significant power producing winds blow from the NE at this site.

Wind Power Class The wind power class is a number indicating the average energy content of the wind resource. Wind power classes are based on the average wind power density at 50 meters above ground, according to the following table. Source: Wind Energy Resource Atlas of the United States (http://rredc.nrel.gov/wind/pubs/atlas/tables/A-8T.html) Wind Power Class Description Power Density at 50m (W/m2) 1 Poor 0-200 2 Marginal 200-300 3 Fair 300-400 4 Good 400-500 5 Excellent 500-600 6 Outstanding 600-800 7 Superb 800-2000 Windographer classifies any wind resource with an average wind power density above 2000 W/m2 as class 8. Probability Distribution Function The probability distribution function f(x) gives the probability that a variable will take on the value x. It is often expressed using a frequency histogram, which gives the frequency with which the variable falls within certain ranges or bins. Wind Turbine Power Regulation All wind turbines employ some method of limiting power output at high wind speeds to avoid damage to mechanical or electrical subsystems. Most wind turbines employ either stall control or pitch control to regulate power output. A stall-controlled turbine typically has blades that are fixed in place, and are designed to experience aerodynamic stall at very high wind speeds. Aerodynamic stall dramatically reduces the torque produced by the blades, and therefore the power produced by the turbine. On a pitch-controlled turbine, a controller adjusts the angle (pitch) of the blades to best match the wind speed. At very high wind speeds the controller increasingly feathers the blades out of the wind to limit the power output. 2009-0005 United States Department of the Interior FISH AND WILDLIFE SERVICE Anchorage Fish and Wildlife Field Office 605 West 4th Avenue, Room G-61 Anchorage, Alaska 99501-2249 In reply, refer to: AFWFO Robin Reich Solstice Environmental Consulting 11760 Woodbourne Drive Anchorage, AK 99516 Re: Bulk Fuel Storage, Power System Upgrades, and Wind Power Development in New Stuyahok (Consultation # 2009-0005) Dear Ms. Reich, Pursuant to section 7 of the Endangered Species Act of 1973, (16 U.S.C. 1531 et seq., as amended; ESA), the Service is responding to your request for concurrence with the determination that power upgrades in the village of New Stuyahok will have no effect on threatened or endangered species. This project, which received initial funding from the Denali Commission, comprises: 1) installation of twenty 27,000 gallon, two 22,300 gallon, one 8,000 gallon, one 5,000 gallon fuel tanks and a power plant on 2.46 acres; 2) installation and operation of three Northwind 100 wind turbines on 100 ft2 pads. Our records indicate that there are no federally listed or proposed species and/or designated or proposed critical habitat within the action area of the proposed project. In view of this, requirements of section 7 of the ESA have been satisfied. However, obligations under section 7 of the ESA must be reconsidered if new information reveals project impacts that may affect listed species or critical habitat in a manner not previously considered, if this action is subsequently modified in a manner which was not considered in this assessment, or if a new species is listed or critical habitat is determined that may be affected by the identified action. This letter relates only to federally listed or proposed species and/or designated or proposed critical habitat under our jurisdiction. It does not address species under the jurisdiction of National Marine Fisheries Service, or other legislation or responsibilities under the Fish and Wildlife Coordination Act, Clean Water Act, National Environmental Policy Act, Migratory Birds Treaty Act, Marine Mammal protection Act, or Bald and Golden Eagle Protection Act. This concludes section 7 consultation on the Bulk Fuel Storage, Power System Upgrades, and Wind Power Development in New Stuyahok. Thank you for your cooperation in meeting our joint responsibilities under section 7 of the ESA. If you have any questions, please contact me at (907) 271-1467. In future correspondences regarding this consultation please refer to consultation numbers 2009-0005. Sincerely, Ellen W.
