The North Slope Borough (NSB) envisions a wind energy and area -wide energy management system, consisting of wind diesel integration, end -use energy efficiency, automated building controls, and conservation. This phase of the project is the feasibility study phase of a three phase project which will include phases for design and permitting, and construction and commissioning for three anticipated wind turbines to supplement the existing power generation and distribution system for the community of Kaktovik. 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 system engineering during this phase of the project. During the construction phase, MSB will recruit an engineering and construction contractor for 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. 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 the project will be reduced fuel costs to the people of Kaktovik. Findings of wind resource versus load demand result in an estimated gross fuel savings of over 48,000 gallons of diesel fuel per year at the Kaktovik 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 o£ • 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. The feasibility study will require $132,000 to complete. For the design and permitting phase of the project, the North Slope Borough will cost approximately $440,000 The construction and commissioning phase of the project requires $3,993,000 to complete. Based on published cost estimates of similar wind diesel projects proposed and existing in rural AEA 11/005 Grant Application Page 4 of 64 09/08/2010 ORITY /domwr---.ENERGYALASAUTHKA Renewable Energy Fund Grant Application Round IV Alaska communities, this rough order of magnitude cost estimate is preliminary. We did a constructability review of the cost estimate with knowledgeable contractors and concluded that this is reasonable rough order of magnitude cost estimate for this stage of the project. 2.7 COST AND BENEFIT SUMMARY 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 design, feasibility, generation and distribution issues to the team. Additionally, the engineering group provides specifications, design and drawings for North Sloe Borough AEA 11/005 Grant Application Page 5 of 64 09/08/2010 ORITY ALASHKA Renewable Energy Fund Grant Application Round IV 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, providing economies of scale for using project resources. 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. 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 conduct the feasibility study. Following the study, NSB plans to subcontract for construction of the foundations and the contractor will manage that construction. In the construction phase, 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. AEA 11/005 Grant Application Page 7 of 64 09/08/2010 ®ALASHKA ENERGY Renewable Energy Fund Grant Application Round IV 3.6 Project Risk Discuss potential problems and how you would address them. During the feasibility study we anticipate the risk of identifying a suitable site that works for all parties involved. The North Slope Borough will collaborate with local stakeholders to identify an agreed upon and appropriate site. A second risk will be managing stake holder perceptions about wind and making sure there is a full understanding of wind energy. The North Slope Borough will hold stake holder meetings to bring awareness and education to stakeholders about wind energy, leading technology and renewable resources. 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 Kaktovik in June 2009 and is functioning normally. To date, the wind resource appears robust with a measured average wind speed at 30 meters of 6.49 m/s. Based on this data alone, Windographer software predicts a Class 5 (excellent) wind resource. Measured turbulence to date is also promising with a mean turbulence intensity of 0.076 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 43,000 gallons. In addition, an estimated 400 gallons of heating fuel will be saved by the utilization of excess wind generated electricity. 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 Kaktovik consists of four diesel -powered engine generator sets: two of 430 kW, and two of 950 kW capacity. Individual generator efficiency is not tracked, but the aggregate diesel generator efficiency in AEA 11/005 Grant Application Page 8 of 64 09/08/2010 /dOwNE?)) ALASHKA Renewable Energy Fund Grant Application Round IV 2008 was assumed to equal 12.78 kWIVgallon (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. 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. Kaktovik sits on the north coast of Alaska on the Beaufort Sea, roughly 320 miles east 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. Kaktovik 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 aides 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 Kaktovik by a community 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 Kaktovik 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. Kaktovik 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. AEA 11/005 Grant Application Page 9 of 64 09/08/2010 ALASKA 4097) Renewable Energy Fund Grant Application Round IV Residents of Kaktovik 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 on the island for power generation and for heating. 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 technologydescription escription Wind power is the renewable energy option of choice for Kaktovik. There are no other alternative or renewable energy options that are currently, commercially viable- the community and NSB has the choice of diesel fuel or wind energy. Northern Power's Northwind 100 kW B model turbine with a 21 meter rotor (NW 100/21) is proposed for Kaktovik. The NW 100 (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 cgacity will be 300 kW. AEA 11/005 Grant Application Page 10 of 64 09/08/2010 /0wFDALASM Renewable Energy Fund Grant Application Round IV Anticipated capacity factor actor HOMER software was used to simulate conditions at Kaktovik 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 is AEP accounts for lost wind production due to all reasons. In this analysis, we will use 90% to calculate net wind turbine production from gross production. - Renewable fraction from HOMER: 16.8% - Capacity factor on net wind production: 26.5% Anticipated annual generation HOMER software estimated gross annual wind production to be 775 MWh with 16 MWh excess electrical energy. Anticipated net annual wind production is 700 MWh. Anticipated barriers We anticipate some environmental concerns, including avian issues and polar bear habitat. Otherwise, no barriers to successful installation and integration of a wind turbine in Kaktovik are expected. Basic integration concept The integration design concept is comprised of three NW100 turbines, a secondary load controller 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 be responsible for providing the necessary and suitable land to site the turbines. AEA 11/005 Grant Application Page 11 of 64 09/08/2010 /4w0v-:)) ORITY ALASHKA Renewable Energy Fund Grant Application Round IV 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 Application for permits will be made no sooner than one year prior to construction to be valid for the construction period. 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 AEA 11/005 Grant Application Page 12 of 64 09/08/2010 /4400L---)) ALASENERGYHORITY KA Renewable Energy Fund Grant Application Round IV • 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. 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 Kaktovik lies on the north shore of Barter Island, between the Okpilak and Jago Rivers on the Beaufort Sea coast. It lies in the 19.6-million-acre Arctic National Wildlife Refuge, an occasional calving ground for the porcupine caribou herd. The area encompasses 0.8 sq. miles of land and 0.2 sq. miles of water. The climate of Kaktovik is arctic. Temperatures range from -56 to 78 7. Precipitation is light, averaging 5 inches, with snowfall averaging 20 inches. Kaktovik, Alaska is located on the northern coast of Alaska and is underlain by continuous stable permafrost. 'There is one known threatened or endangered specie, the Polar Bear, in the Kaktovik vicinity. 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. Kaktovik 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. The engineering contractor will organize a pre -application meeting to be coordinated through the ADNR, OC&OM office for the Kaktovik, 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. AEA 11/005 Grant Application Page 13 of 64 09/08/2010 ORITY ®ENERGYALASAUTHKA Renewable Energy Fund Grant Application Round IV 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 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 ofi?roposed renewable energy system This application is for the feasibility study. We are requesting $132,000 to complete this study. The North Slope Borough will provide $13,200 as a 10% cash match for this phase of the project. The North Slope Borough also financed the wind study for Kaktovik out of its own operating budget — an estimated outlay of $42,500. We estimate that the completed (constructed) project will cost a total of $4,565,200. We hope to propose for design and 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.) This phase of the project will be operated by the North Slope Borough working with a contractor to conduct the feasibility study. Progress reports and financial reporting will be handled by NSB program managers and staff. 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 croiect North Slope Borough is the owner/operator of the utility in this community; therefore, the Power Purchase/Sale is not required.

Download the form, complete it, and submit it as an attachment. Document any conditions or sources your numbers are based on here. See Attachment B. Wind Resource Study Report SECTION rr 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 cost based rate) • 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 ro A wind study analysis has been conducted for this project. The findings in 2010 follow. HOMER— projected annual fuel savings: 20-year lifetime fuel savings (gallons): 960,000 gallons @ $4.09/gal, escalating at 4%/year gives a total savings of $5.3 MM. - 20-year lifetime energy savings (kWh): 14,000 MWh @ $032/kWh fuel cost, escalating at 4%/year gives a total savings of $6.6 MM - Non -economic benefits — CO2 reduction (@22.2 #/gallon CO2): 530 T/yr or 10,600 tons in a 20-year life The non -economic benefits to the Alaskan population at large will be from the reduced carbon footprint of the power plant. By reducing the amount of fuel burned at the Kaktovik power plant by over 13%, we will prevent over 548 metric tons of carbon dioxide from entering the atmosphere each year. Other significant emissions improvements are a reduction of 1350 kg/year of carbon monoxide and 12,100 kg/year of nitrogen oxides. 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 AEA 11/005 Grant Application Page 15 of 64 09/08/2010 /44NEF-E) ALASHKA Renewable Energy Fund Grant Application Round IV • 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 operations and maintenance phase will become part of the annual NSB operations budget. 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 O&M program with the North Slope Borough. The new Northwind 100B model requires only one maintenance visit each year. The three turbines for Kaktovik will require a combined annual maintenance cost of $10,500.

Given the anemometer problems, mettower data as collected is not useful for calculating mean wind speed, but inserting synthesized data to the data set yields a wind resource prediction in -line with the AWOS data sources. Other parameters, including turbulence, wind shear, and directionality of winds, indicate a desirable wind resource for wind power development.

Vaught photo Page 4 Alternate wind site behind powerplant; D. Vaught photo Data recovery Data recoveryto date in Kaktovik was poor, with only 62 to 71 percent data return from the anemometers and wind vane with all of the missing data representing the winter months. This was due to several problems. First was loss of a data card and hence all data from Oct. 2 to Nov. 13. Then, beginning in early December, a number of apparent icing events rendered the anemometers and wind vane inoperable for much of the month. In early January, the two 30 meter level (channels 1 and 2) anemometers broke off the tower, apparently as a result of icing loads and high winds, and were not replaced until March 3. Throughout winter and spring, frequent and severe icing events resulted in significant data loss to the anemometers and wind vane. Note also much data loss from the relative humidity sensor occurred as well. The RH sensor lost function due to loss of battery power with loss of daylight (for recharge via the PV panels) and for unknown reasons, sensor function did not return with return of sunlight in spring.

The extremely cold arctic temperatures of Kaktovik contributed to the high wind power density. it is problematic, however, analyzing wind data with significant concentrated data loss, such as occurred in Kaktovik with the missing data card, broken 30 meter anemometers, and many icing events. 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 wind data collected and noting that two long-term airport AWOS data sources confirm a robust wind resource in Kaktovik, continuing a wind study with heated sensors is not absolutely necessary.

Caution should be exercised though in that one month of data —October 2009 —had to be removed due to the lost data card and data recovery in general was problematic in Kaktovik. That said, extreme wind analysis indicates a desirable situation in Kaktovik: moderately high mean wind speed combined with relatively low (probable) extreme wind speeds. This may be explained by particular climactic aspects of Kaktovik which because of its extreme northerly latitude, is not exposed to Gulf of Alaska storm winds which tend to significantly increase the long-term probability of damaging winds. Industry standard reference of extreme wind is the 50 year, 10-minute average probable wind speed, referred to as Vfef. For Wainwright, this calculates to 35.4 m/s, belowthe threshold of International Electrotechnical Commission (IEC) 61400-1, 3rd edition criteria (of 37.5 m/s) for a Class III site.

The result is high air density. Calculated air density exceeds standard air density for a sea level elevation (1.225 Kg/m3) by over eight percent.

At most stations, AWOS/ASOS data has been collected for twenty-five or more years. Barter Island DEW Station (ICAO station identifier: PABA) data has been collected by an AWOS since 1973. AWOS data summarized below is through 2004. The AEA report documents data from AWOS sensor, which is 8 meters above ground level. To compare this data to the met tower lower sensor height of 20, the AWOS data was adjusted using an exponent extrapolation function with a power law exponent value of 0.097, the measured shearvalue at the met tower site. Comparing to the met tower 20 meter anemometer (both the collected data set and the synthesized data set), one can see that average wind speeds recorded by the met tower are approximately that predicted by the Barter Island DEW Station AWOS data. By itself, the AWOS data indicates a Class 6 wind resource, hence confirming the wind resource measured at the met tower site, data recovery problems aside.
