This phase of the project involves the final design and permitting for three anticipated wind turbines to supplement the existing power generation and distribution system for the community of Wainwright. Participants in the project include North Slope Borough, a contracted engineering/design firm, and Northern Power Systems of Barre, Vermont (wind turbine experts and supplier). The contractor will provide overall project management and electrical system engineering for the project, as well as, in the final phase of the project, the design and installation of all civil works, erection of the wind turbines, and installation of all ancillary electrical systems. Northern Power will provide Northwind 100B model wind turbines plus startup & commissioning services. AEA 11/005 Grant Application Page 3 of 62 09/08/2010 �GM--) ALASKA Renewable Energy Fund Grant Application Round IV 2.5 PROJECT BENEFIT Briefly discuss the financial and public benefits that will result from this project, (such as reduced fuel costs, lower energy costs, etc.) When this project is completely constructed and in operation, the primary financial benefit from this project will be reduced fuel costs to the people of Wainwright. Findings of wind resource versus load demand result in an estimated gross fuel savings of over 51,000 gallons of diesel fuel per year at the Wainwright plant, from efficiency improvements due to new automated switchgear, from diesel -powered generation being displaced by wind, and by displacing diesel - fired hot water heating with excess electrical energy from the wind turbines. In addition to the direct fuel reduction are the benefits of- - reduced long-term dependence on outside sources of energy; - reduced exposure to fuel price volatility; - reduced air pollution resulting from reducing fossil fuel combustion; - reduced possibility of spills from fuel transport & storage; and - reduced overall carbon footprint and its contribution to climate change. 2.6 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. For the design and permitting phase of the project, the North Slope Borough is requesting funding in the amount of $400,000 The construction and commissioning phase of the project requires $3,993,000 to complete. Design & Permitting will cost $440,000. Based on published cost estimates of similar wind diesel projects proposed and existing in rural Alaska communities, this rough order of magnitude cost estimate is preliminary. We consulted with STG, Incorporated, the most experienced construction contractor for rural Alaska wind projects, to review and confirm our preliminary budget numbers. 2.7 COST AND BENEFIT SUMARY Include a summary of grant request and your project's total costs and benefits below.

SECTION 3 — PROJECT MANAGEMENT PLAN Describe who will be responsible for managing the project and provide a plan for successfully completing the project within the scope, schedule and budget proposed in the application. 3.1 Project Manager Tell us who will be managing the project for the Grantee and include contact information, a resume and references for the manager(s). If the applicant does not have a project manager indicate how you intend to solicit project management support. If the applicant expects project management assistance from AEA or another government entity, state that in this section. North Slope Borough's project management approach to this project, and to its overall energy upgrade program, is to utilize a team approach consisting of North Slope Borough staff, external consultants and general contractors. Mr. Kent Grinage will be the Program Manager and will be the contact for any technical questions. His resume is attached. Mr. Jack Smith is the Grants Administrator and will handle grant paperwork, amendments and financial matters. North Slope Borough provides a project team from its operating staff. The Program Manager, Kent Grinage, provides oversight to Project Administrators who interface with the Engineering Consultant and General Contractor. The PM and PA group provides internal focus and coordination of special projects including project development, planning, construction coordination, and reporting. The Engineering Consultant of the North Slope Borough provides technical input on generation and distribution issues to the team. Additionally, the engineering group provides specifications, design and drawings for North Slope Borough construction of diesel power plants and distribution systems. The Engineering Consultant provides construction administration and commissioning input on behalf of new construction performed by the North Slope Borough contractor. The manager of administrative services, Jack Smith, provides support in accounting, payables, financial reporting, and capitalization of assets in accordance with NSB guidelines. The project management team's structure is designed to provide flexibility for the North Slope Borough participants. They have operational responsibilities to the Borough as well as project development responsibilities. This project is being funded and completed in phases. This approach works well with the North Slope Borough's management style. The functional - interface relationships allow engineering tasks, village government and public relations tasks, procurement functions, and internal construction operations to be dovetailed into the project development process. Cross utilization of talent and resources is an advantage to the project delivery process, providina economies of scale for using project resources. AEA 11/005 Grant Application Page 5 of 62 09/08/2010 /46NOV'D ALASHKA Renewable Energy Fund Grant Application Round IV For project delivery, an amalgamated team approach is utilized. To support the North Slope Borough team, design consultants and construction services managers are selected. Both disciplines are derived from a resource bank of professional firms with applicable histories of performance in rural Alaska. The construction services manager works concurrently with the design consultant through design development to provide constructability insight and value engineering to maximize the overall effectiveness of the final construction documents. If the design/permitting phase is funded and assuming there will be another round of funding available in 2011, design will be completed, construction funding secured, and construction will be in 2013. Concurrent with design development, material and equipment procurement packages are formulated by the General Contractor (GC) in collaboration with North Slope Borough's Program Manager. Each package is competitively procured or issued from NSB materials. Purchase orders are formulated with delivery dates consistent with dates required for barge or air transport consolidation. The GC tracks the shipments and provides handling services to and around the destination project sites. For the future phase, construction and commission, the GC is responsible for the construction activities for all project components of the facility upgrade. Local labor forces are utilized to the maximum extent possible to construct the projects. Local job training is provided as a concurrent operation under the management and direction of the GC. All construction costs, direct and indirect are reimbursed on a Fixed Fee reimbursement to the GC or paid directly by North Slope Borough. In the next phase, North Slope Borough will be responsible for managing the commissioning process in content with the GC, designers and vendors. That entails testing and training of operational personnel, as well as providing for all contract closeout documents. North Slope Borough's concern and objective is to have a managed project delivery approach from inception through operation. 3.2 Project Schedule Include a schedule for the proposed work that will be funded by this grant.

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. North Slope Borough will ultimately be responsible for successful completion of the project, using partners that have successfully installed similar systems in the recent past. Electrical system engineering will be subcontracted, using current internal procurement practices and selection of engineering service providers from prequalified organizations. The contracted A & E firm will design the wind turbine foundations. NSB will subcontract for construction of the foundations and the contractor will manage that construction. One hundred kilowatt Northwind 100B wind turbines from Northern Power will be used. The permanent magnet, direct -drive NW 100/21 is the latest wind turbine model from Northern Power, based on earlier Northwind 100 kW wind turbine models that Alaska Village Electric Cooperative has installed and operated in wind/diesel applications for several years now. Developed in conjunction with NASA, NREL, and NSF specifically for remote use in extreme environments, the NW 100/21 embodies the most recent design practices in the industry. Northern Power's experience with wind/diesel control systems complements North Slope Borough's wind power needs. 3.5 Project Communications Discuss how you plan to monitor the project and keep the Authority informed of the status. North Slope Borough will assign a project manager to the project. One responsibility of the project manager will be to compile periodic progress reports for use by the Authority. Monthly project coordination meetings will be held with the project team to track progress and address issues as they arise. 3.6 Project Risk Discuss potential problems and how you would address them. During the design phase, we anticipate the following risk factors and potential mitigation factors: 1. Inaccurate or Incomplete Power Plant Data. During the wind study phase, we identified several data gaps associated with power plant efficiency and performance. We intend to mitigate this by developing a data collection protocol on power plant performance and re- constructing historical performance where we have data gaps. 2. Technology Performance. Alaska's North Slope represents some of the harshest climatic environment- technology may not perform as intended. We intent to mitigate this with collaboration with utilities such as Alaska Village Electric Cooperative, the Alaska Center for Energy and Power, and technology providers to assure that the technology is appropriate and adapted for the targeted environment. AEA 11/005 Grant Application Page 8 of 62 09/08/2010 /44WzE_-_))ORITY ALASAUTENERGYHKA Renewable Energy Fund Grant Application Round IV 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(s) 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 form 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. A met tower was erected at the proposed wind turbine site in Wainwright in June 2009 and is functioning normally. To date, the wind resource appears robust with a measured average wind speed at 30 meters of 7.05 m/s (6/19 thru 7/10). Based on this data alone, Windographer software predicts a Class 4 (good) to low 5 (excellent) wind resource. Measured turbulence to date is also promising with a mean turbulence intensity of 0.072 at 15 m/s, classifying the site so far as IEC 61400-1 3rd edition (IEC3) category C. Extreme wind probability is unknown, but IEC3 Class II or III is likely. The estimated annual fuel displaced for electricity generation as predicted by HOMER software, is 46,000 gallons. 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. The existing power plant at Wainwright consists of five diesel -powered engine generator sets: three of 430 kW, and two of 950 kW capacity. Individual generator efficiency is not tracked, but the aggregate diesel generator efficiency in 2008 was assumed to equal 13.5 kWh/gallon (based on efficiency data of AVEC and other rural Alaska rural utilities). 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. The existing power plant produces electrical energy by burning diesel fuel in engine -driven generators. By adding wind turbines to the existing system, we expect the project to provide the same amount of electrical energy using substantially less diesel fuel than is true today. In addition to offsetting much of the diesel -generated electricity, we also expect to use whatever wind - generated energy that exceeds electrical demand to heat water, also displacing diesel fuel that is presently burned in boilers. AEA 11/005 Grant Application Page 9 of 62 09/08/2010 ALASM Renewable Energy Fund Grant Application Round IV 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. Wainwright sits on the west coast of Alaska on the Arctic Ocean, 85 miles southwest of Barrow. It is subject to severe cold winter temperatures, extended periods of darkness and blowing snow. Reliable electric service is essential to maintaining home heating systems necessary to safeguard the health of the population. Wainwright is classified as 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 Wainwright by a health aide. Therefore 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. The heaviest consumers of power in villages of the North Slope Borough are the water and sewer facilities. Additionally the underground utilities are thawed by electrical heat trace. If one of these heat traces is left without power, systems will freeze up and shut down. Water in Wainwright comes from a fresh water surface pond which must be processed for use as potable water. 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. Wainwright is subject to long periods of darkness. Reliable electric service is essential for the operation of home lighting, streetlights and security lighting. Children walk to school and outside lighting helps them find their way and be on the look -out for hazards such as deep snow or in the extreme case, polar bears. Residents of Wainwright rely on a subsistence lifestyle where food is gathered and harvested and then stored for later use. Refrigeration is essential for the extended storage of perishable food stuffs. Reliable electric service is essential for proper freezer storage of food during summer months. We expect the addition of wind turbines to the electric generation system to reduce the amount of diesel fuel used in Wainwright for power generation and for heating. AEA 11/005 Grant Application Page 10 of 62 09/08/2010 /4&1) AENELASKA Renewable Energy Fund Grant Application Round IV 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 Renewable energy technology description Wind power is the renewable energy option of choice for Wainwright. There are no other alternative or renewable energy options that are currently, commercially viable. Northern Power's Northwind 100 kW B model turbine with a 21 meter rotor (NW 100/21) is proposed for Wainwright. The NW100/21 (B model) represents a new generation of wind turbines. Its permanent -magnet, direct -drive architecture is the current state of the art for advanced wind turbine design. That architecture overcomes many of the challenges of connecting old-style induction generators to electrical distribution grids. The permanent -magnet generator is connected to a full power converter that converts its variable, low -frequency, alternating - current output to direct current, then back to tightly regulated alternating current for output to the grid. The permanent -magnet generator requires no reactive power to energize its magnetic field, removing that influence from the grid. The power converter allows a broad degree of control over the form and quality of the power output to the grid. The capacitance and active controls in the power converter allow reactive power to be either consumed or produced by the Northern 100 regardless of its real power output, even in the complete absence of wind. The turbine controls allow power output to be controlled by dynamic grid conditions, including automatic output reduction or complete shutdown, regardless of wind conditions. The combination of advanced controls and integrated disk braking allows gradual ramping of turbine output up or down, minimizing flicker and maximizing usable power. Optimum installed capacity The system we plan consists of three (3) NW100/21 turbines to operate with the existing diesel plant as a wind -diesel hybrid power system. Installed wind power capacity will be 300 kW. Anticipated capacity factor HOMER software was used to simulate conditions at Wainwright with three Northwind 100 wind turbines running in conjunction with the existing power plant. HOMER calculates gross energy production with no allowance for power plant downtime, turbine or generator maintenance, equipment curtailment or any other reason. Northern Power notes that roughly 90% of annual energy production estimates from Homer modeling are observed in Alaskan villages. This reduction in AEP accounts for lost wind production due to all reasons. In this analysis, we will use 90% to calculate net wind turbine production from HOMER's gross production estimate. - Renewable fraction from HOMER: 16.3 % AEA 11/005 Grant Application Page 11 of 62 09/08/2010 /460"V�)D ALASKA Renewable Energy Fund Grant Application Round IV - Capacity factor on net wind production: 30.4% Anticipated annual generation HOMER software estimated gross annual wind production to be 890 MWh with 0 MWh excess electrical energy. Anticipated net annual wind production is 800 MWh. Anticipated barriers No barriers to successful installation and integration of a wind turbine in Wainwright are expected. The project design is modeled on recent successful projects of similar design. Basic integration concept The integration design concept is comprised of three NW 100 turbines, a secondary load boiler to augment an existing diesel generator heat recovery loop (if deemed necessary after further analysis), a secondary load controller to manage the "dumping" of excess electricity (if necessary), a SCADA system to manage the combine operation of the diesel generators and wind turbine, and the SmartView system to enable remote monitoring and control of the wind - diesel hybrid power plant. Alternatively, and this would require more analysis, if there will not be significant excess electricity generated and it appears from preliminary analysis that there won't, a secondary load controller and boiler could be replaced by a dispatch control feature that would serve to curtail one of the wind turbines during the rare occurrences where wind power output equals or exceeds the load demand. Delivery methods The wind -generated electrical energy will be delivered using the existing electrical distribution grid. 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. North Slope Borough has substantial land in the villages and will provide the necessary and suitable land to site the turbines.

The following permits and/or authorizations will be necessary for installation of the wind turbines: • North Slope Borough permitting • USACE Section 404/401 Wetlands permit and Water Quality Assurance • ADNR, OC&OM Coastal Zone Consistency Determination • Title 16 Fish Habitat Permit • SHPO "No Historic Properties Affected" • Storm Water Pollution Prevention Plan • Alaska Pollutant Discharge Elimination System • Vegetation Clearing Not Permitted between May 20 and July 20, except for black scoter habitat where the end of the avoidance period is August 10 • FAA 7460-1 Notice of Proposed Construction or Alteration Environmental & Permitting Review and Due Diligence Deliverable. The deliverable of this step is a 5 page report detailing findings of the agency meeting and discussions. AEA 111005 Grant Application Page 13 of 62 09/08/2010 ORITY /4@N'FLD)ENERGYALASAUTHKA Renewable Energy Fund Grant Application Round IV 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 Wainwright, Alaska is located on the western coast of Alaska and underlain by continuous stable permafrost. 'There are known threatened or endangered species in the Wainwright vicinity. Both spectacled and Steller's eider are known to nest in the area. Both are threatened species. The black brant, long tailed duck, red -throated loon and yellow -billed loon are also sensitive species in the area. The USFWS has published a voluntary Interim Guidelines to Avoid and Minimize Wildlife Impacts from Wind Turbines document. Consideration of threatened or endangered species and for birds, in general, is critical to wind farm development. Depending on location and proximity to nesting habitat, a USFWS Section 7 consultation could be required. Wainwright is in the North Slope Borough Coastal Resource Service Area and is subject to a Coastal Zone Consistency Determination. Coastal Zone review is conducted through the State of Alaska Department of Natural Resources, Office of Coastal and Ocean Management. Coastal Zone review functions as a clearing house for all permits issued by State agencies. Environmental Approach. WHPacific will organize a pre -application meeting to be coordinated through the ADNR, OC&OM office for the Wainwright, Alaska Wind Diesel Project. All agencies, including federal agencies, will be asked to participate. The meeting will identify and discuss appropriate permit issues and provide agency perspective on the proposed development. Discussions should include actions to avoid, minimize and mitigate wetlands impacts. Preliminary concerns for impacts to the National Preserve and possible cultural sites will be identified. Results of this agency pre -application meeting will be a three to five page meeting report summarizing agency concerns, issues and possible mitigation or compensation proposals. This will be as comprehensive as possible but may not identify all permits required for project development given the preliminary nature of the development proposal. 4.4 Proposed New System Costs and Projected Revenues (Total Estimated Costs and Projected 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 AEA 11/005 Grant Application Page 14 of 62 09/08/2010 /44EffE_-__))ORITY ALASAUTENERGYHKA Renewable Energy Fund Grant Application Round IV 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 This application is for the design and permitting phase. We are requesting $400,000 to complete the design and permitting phase. The North Slope Borough will provide $40,000 as a 10% cash match for this phase of the project. The North Slope Borough also financed the wind study for Wainwright out of its own operating budget — an estimated outlay of $42,500. We estimate that the completed (constructed) project will cost a total of $4,433,000. We hope to propose for construction funds in the event there is another AEA funding round in 2011. 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. (Note: Operational costs are not eligible for grant funds however grantees are required to meet ongoing reporting requirements for the purpose of reporting impacts of projects on the communities they serve.) The new Northwind 100 B model requires only one maintenance visit each year. The three turbines for Wainwright will require a combined annual maintenance cost of $10,500. This cost will be funded by ongoing energy sales in the village. 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 pmject North Slope Borough is the owner/operator of the utility in this community; therefore, the Power Purchase/Sale is not required. 4.4.4 Project Cost Worksheet Complete the cost worksheet form which provides summary information that will be considered in evaluating the project.

Non -economic benefits - - CO2 reduction (@ 22.2 #/gallon CO2): 510 T/yr or 10,200 tons in a 20-year life Additional benefits include local jobs associated with local generation of power. The program will work in conjunction with Northern Power to train local power plant operators with the operations and maintenance of the wind diesel system. This training will have a multiplier effect, by increasing the knowledge base and furthering the competencies of the local workforce. We will explore other tax credits as a benefit to the project. Also, any future value laid to carbon offsets will contribute to additional savings as a result to the project. SECTION 6— SUSTAINABILITY 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. • How you propose to finance the maintenance and operations for the life of the project • Identification of operational issues that could arise. • A description of operational costs including on -going support for any back-up or existing systems that may be require to continue operation • Commitment to reporting the savings and benefits Once constructed, the proposed wind diesel system will be fully integrated into the North Slope Borough -owned and operated utility system. Therefore, the proposed business structure will become part of the annual operations and maintenance budget, and any significant capital upgrades will be part of the annual CIP process. The North Slope Borough has the existing infrastructure that will serve this project and is inherently sustainable. This design and permitting phase will become part of the annual NSB operations budget. AEA 11/005 Grant Application Page 16 of 62 09/08/2010 /ZEF)) ALASM Renewable Energy Fund Grant Application Round IV Operational issues that could arise are in integrating between wind and diesel systems and the cost of training the current plant operator on the wind/diesel system. Providing operations and maintenance in an arctic environment can be costly, but will come under the infrastructure of the North Slope Borough. The new Northwind 100B model requires only one maintenance visit each year. The three turbines for Wainwright will require a combined annual maintenance cost of $10,500. This cost will be funded by ongoing energy sales in the village. Power Plant operators will be trained to collect data and will be required to report all cost savings and benefits. SECTION 7 — READINESS & COMPLIANCE WITH OTHER GRANTS Discuss what you have done to prepare for this award and how quickly you intend to proceed with work once your grant is approved. Tell us what you may have already accomplished on the project to date and identify other grants that may have been previously awarded for this project and the degree you have been able to meet the requirements of previous grants. The North Slope Borough recently (9/16/10) received Round III funding that will be implemented in Fall 2010. When the Round IV award is made, the current phase will be completed. The NSB funded wind study has been completed and reports are appended here. The NSB has an on -going area -wide, non grant funded, initiative for energy management with Johnson Controls. Over the last 30 years, Johnson Controls' Building Efficiency business unit has implemented energy efficiency work that has resulted in over $413 of savings for their customers. They are also a leading provider of renewable energy solutions and have a national portfolio of installations including wind, solar, geothermal, biomass and landfill gas to energy. SECTION 8— LOCAL SUPPORT Discuss what local support or possible opposition there may be regarding your project. Include letters of support from the community that would benefit from this project. North Slope Borough is the provider of local energy in the Borough. They own all local utilities, so a resolution from the Borough Assembly is included here as Attachment G. Other letters of support may be found in Attachment D. SECTION 9 — GRANT BUDGET Tell us how much you want in grant funds Include any investments to date and funding sources, how much is being requested in grant funds, and additional investments you will make as an applicant. Include an estimate of budget costs by milestones using the form — GrantBudget3.doc AEA 11/005 Grant Application Page 17 of 62 09/08/2010 /401-) AENELASM Renewable Energy Fund Grant Application Round IV Provide a narrative summary regarding funding sources and your financial commitment to the project. The design and permitting phase will require funds from both the Alaska Energy Authority and the North Slope Borough. We are asking AEA for $400,000 and the NSB will match that with 10% in cash ($40,000). These funds will be used to hire a contractor to design the turbine sites. Permitting, environmental work, labor, systems designs, and the final business and operational plan will be paid for by this award.

Vaught photo Data Recovery Data recovery in Wainwright was mostly acceptable, with 75 to 80 percent data recovery of the anemometers and wind vane. The exception is the 30 m A anemometer which lost a cup in December orJanuary. This rendered the sensor useless and all subsequent data was removed from analysis. Note that data recovery in December and January was particularly poor, apparently due to hoarfrost conditions during this deep cold period of mid -winter. It is curious that similar data loss was not observed at the Point Hope met tower during the same time period. Note also that data loss from the relative humidity (RH) sensor was due to voltage drawdown of the iPack battery during the dark months of winter (the battered is recharged with photovoltaic panels). Functionality of the RH sensor eventually recovered after return of daylight in springtime.

The cold arctic temperatures of Wainwright contributed to the high wind power density. It is problematic, however, analyzing wind data with significant concentrated data loss, such as occurred in Wainwright during November through January, then again in March. To correct this problem, synthetic data was inserted in the data gaps to create a more realistic wind speed data profile. To be sure, long segments of synthetic data introduce uncertainty to the data set, but missing data does as well. To overcome this uncertainty, improved data collection with heated sensors would be necessary. But, considering the robust wind resource AEA11-005 Grant Application Page 50 of62 7/21/2010 /.,ALASKAH Renewable Energy Fund Grant Application Round IV Wainwright Wind Resource Report Page 6 measured and noting the long-term airport AWOS data confirming the wind resource measured by the met tower, continuing a wind study with heated sensors is not truly necessary in Wainwright.

Extreme wind analysis indicates a highly desirable situation in Wainwright: moderately high mean wind speeds combined with low extreme wind speed probabilities. This may be explained by particular climactic aspects of Wainwright which include prominent coastal exposure, offshore wind conditions, and due to the extreme northerly latitude, lack of exposure to Gulf of Alaska storm winds. Industry standard reference of extreme wind is the 50year, 10-minute average probable wind speed, referred to as V,,f. For Wainwright, this calculates to 24.8 m/s, belowthe threshold of International Electrotechnical Commission (IEC) 61400-1, 3rd edition criteria (of 37.5 m/s) for a Class III site.

At most stations, AWOS/ASOS data has been collected fortwenty-five or more years. Wainwright Airport (ICAO station identifier: PAWI) data was first collected in 1973 by an AWOS which was later upgraded to ASOS. The AEA report documents data from AWOS/ASOS sensor, which is 8 meters above ground level. To compare th is data to the met tower upper sensor height of 30 meters, the data was adjusted using an exponent extrapolation function with a power law exponent value of 0.142. Comparing to the met tower 30 meter B anemometer (both the collected data set and the synthesized data set), one can see that average wind speeds recorded by the met tower are higher than that predicted by the AWOS/ASOS data. This would account for the higher wind class prediction of the met tower (high Class 4/low Class 5) over the airport data (low Class 4). There may be a number of reasons for this discrepancy, including closer proximity of the met tower to the coast and extrapolation errors in translating the eight meter airport data to thirty meters. Comparison discrepancies aside, the Wainwright airport data confirms the robust wind resource recorded by the met tower.
