Anaktuvuk Pass Geothermal Feasibility Study 2.2 Project Location — Include the physical location of your project and name(s) of the community or communities that will benefit from your project. Location — latitude and longitude or street address or community / communities served: The location of this project is in Anaktuvuk Pass Alaska. Anaktuvuk Pass will be the community affected by the outcomes of this project. 2.3 PROJECT TYPE Put X in boxes as appropriate 2.3.1 Renewable Resource Type Wind Biomass or Biofuels Transmission of Renewable Energy Small Natural Gas Hydrokinetic Storage of Renewable Hydro, including run of river X Geothermal, including Heat Pumps X Heat Recovery from existing sources Solar Other (Describe) 2.3.2 Proposed Grant Funded Phase(s) for this Request (Check all that apply) X Reconnaissance Design and Permitting Feasibility Construction and Commissioning Conceptual Design 2.4 PROJECT DESCRIPTION Provide a brief one paragraph description of your proposed project. The North Slope Borough (NSB) envisions a combination of geothermal energy and waste heat recovery to enhance district space heating for residential use. Existing waste heat includes the power plant and warm processed waste -water from the treatment plant. This reconnaissance study is intended to determine if known underground resources are capable of providing geothermal energy in combination with waste heat recovery to support space heating of residential homes, commercial and public buildings. The study will include collection of existing data, identification of additional resources, and analysis to prepare recommendations. 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.) AEA 12-001Grant Application Page 2 of 63 7/1/2011 r,ww::) ALASENERGY AUTHORITY KA Renewable Energy Fund Grant Application Round 5 When this project is completed and operational, the primary financial benefit will be reduced heating fuel costs to the residents of Anaktuvuk Pass. It is estimated geothermal resources could save home owners, commercial buildings, and public facilities over 48,000 gallons of diesel heating fuel per year for space heating of homes and buildings in the community. A reduction in the diesel fuel necessary for basic home heating would enable residents in a high unemployment subsistence community to improve the quality of life by spending valuable financial resources on improvement of diet, health care, and other needs. In addition to decreased fuel consumption, benefits include reduction of: • long-term dependence on imported oil; • exposure to fuel price volatility; • pollution from fossil fuel combustion; • risks of spills from fuel transport & storage; and • 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 Reconnaissance study will require $186,956 to complete. The North Slope Borough anticipates the Feasibility phase will requires an additional $145,000. Design and permitting is estimated at $400,000, though these costs may vary depending on the location of the resource identified and actual permitting that might be involved. Construction and commissioning for the project is estimated at $2,100,000. The proposed project budget is a preliminary estimate based on anticipated components that might be needed and would be subject to modification once identification of resource is completed and project feasibility is defined. These estimates have been reviewed with engineering contractors experienced in rural Arctic Alaska, who concur they are reasonable based on the limited information currently available. 2.7 COST AND BENEFIT SUMMARY Include a summary of grant request and your project's total costs and benefits below.

AEA 12-001 Grant Application Page 3 of 63 7/1 /2011 /© ALASKA ENERGY AUTHORITY Renewable Energy Fund Grant Application Round 5 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. The North Slope Borough's (NSB) project management approach to this project, and its overall energy upgrade program, is utilizing a team consisting of North Slope Borough staff, external consultants and general contractors. Mr. Kent Grinage is the Program Manager and contact for technical questions. His resume is included. Mr. Jack Smith is the Grants Administrator and provides coordination of grant paperwork, amendments and financial matters. The NSB provides a project team from its operating staff. Kent Grinage provides oversight to Project Administrators who interface with engineering professionals, consultant, and other contractors. The Project Manager and Project Administrators provide internal focus and coordination, including project development, planning, construction coordination, and reporting. Engineering professionals provide technical input on design, feasibility, generation and distribution issues. Additionally, the engineering group provides specifications, design and drawings for construction of diesel power plants and distribution. The Engineering Consultant provides construction administration and commissioning input on behalf of new construction performed. Jack Smith in cooperation with the NSB Grants Division provides support in grant management, accounting, payables, financial reporting, and capitalization of assets in accordance with municipal regulations. The team structure is designed to provide flexibility. They have operational obligations to the Borough as well as project development responsibilities. This project is would be funded and completed in phases. This approach works well in the Borough's management style. The functional -interface relationships allow engineering, village government and public relations tasks, procurement, and internal operations to be dovetailed into the project development process. Cross utilization of talent and resources is an advantage to project delivery, providing economies of scale. For project delivery, an amalgamated team approach is utilized. To support the NSB team, design consultants and construction services managers are selected from professional firms with applicable histories of performance in rural Alaska. The construction services manager works concurrently with design consultants through development to provide insight and value engineering to maximize effectiveness of 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. The North Slope Borough will ultimately be responsible for successful completion of the project, using partners with expertise in working in the Arctic region, energy resource development, and other technical knowledge. In addition to the project management personnel of the North Slope Borough noted previously, the following resources have been identified as potential assets to this project. • RSA Engineering / Dick Armstrong, PE — Mechanical Engineering • Golder & Associates / Duane Miller, PE — Geotechnical Engineering • ASRC Energy Services / Stephen Ranger, PE— Civil Engineering • ASRC Energy Services / Eva Burk — Project Engineer • ASRC Energy Services / Ben Vetter, PMP — Project Manager • Dr. Rorik Peterson, UAF College of Engineering and Mines 3.5 Project Communications Discuss how you plan to monitor the project and keep the Authority informed of the status. The North Slope Borough will assign a project manager. One responsibility of the project manager will be to compile periodic progress reports that will be combined with financial statements to keep the Authority informed of project status. 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 reconnaissance phase of this project, the North Slope Borough anticipates that weather and seasonal related factors beyond the control of the municipality will present the greatest risk to project completion. While planning efforts will be performed in an attempt to minimize these impacts, the North Slope Borough recognizes that some flexibility is to be expected since these factors cannot otherwise be mitigated. Community residents are often concerned about work involving the environment. The North Slope Borough and its project partners will collaborate with local stakeholders to educate them about the purpose of the project, impacts if an adequate geothermal source is identified, and the potential benefits to the residents of Anaktuvuk Pass. Considering capture of nearly any energy source involves some impact to the environment, the North Slope Borough and its project partners will need to insure residents are properly informed of project progress. As identified by the Alaska Energy Authority, investigation of potential renewal energy resources remains a relatively new venture and it will be important that timely and accurate information be provided to residents. The North Slope Borough will hold stake AEA 12-001 Grant Application Page 6 of 63 7/1/2011 ALASKA ENERGY Renewable Energy Fund Grant Application Round 5 holder meetings to bring awareness and education to stakeholders about geothermal energy. 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. This reconnaissance study will examine previously acquired geotechnical and soil temperature data and obtain additional data as necessary to ascertain if a geothermal ground source heat pump system combined with waste heat from the existing power plant and waste -water treatment plant can provide a benefit to the community. The high cost of diesel heating fuel is a burden to home owners and the North Slope Borough. There is no permafrost ground in Anaktuvuk Pass and indications from previous geotechnical reports identify that warm ground water up to 40 °F can be found throughout most of the year. This indicates a source of below ground water supply that could be used as a heat source for a ground loop. Ground water has a higher heating capacity than `dry ground' and thus could be a potential source of heat energy. This reconnaissance study is necessary to determine the extent of a geothermal resource and if it sufficient to be of benefit in reducing the dependence on diesel heating fuel as the only source of energy. There are no other known energy resources available to Anaktuvuk Pass. Wind and solar energy are not of sufficient quantity during the winter months. There are no nearby sources of coal bed methane gas or natural gas. The only access to Anaktuvuk Pass is by air; it is approximately 90 miles west of the Dalton Highway, thus all heating and other fuels must be transported to the community by expensive air cargo methods. 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 only access to the community of Anaktuvuk Pass is via air travel. Thus, diesel fuel to operate the community Power Plant is hauled by tanker truck from Fairbanks to Prudhoe Bay, were it is hauled in smaller Everts Air planes capable of landing in the community. Transporting the more than 500,000 gallons need involves approximately 120 air cargo flights per year. AEA 12-001Grant Application Page 7 of 63 7/1/2011 r4ZI--)A ASH Renewable Energy Fund Grant Application Round 5 The existing power plant in Anaktuvuk Pass consists of five diesel -powered engine generator sets: three of 325 kW, and two of 910 kW capacities. Individual generator efficiency has not been tracked, but the aggregate diesel generator efficiency in 2008 was assumed to equal 12.78 kWh/gallon (based on efficiency data of AVEC and other rural Alaska rural utilities). Individual homes and other properties in the community utilize a combination of boilers and furnaces. Estimates indicate there are approximately 100 boilers and furnaces utilized for residential heating and another 40 for commercial type properties including the health clinic, post office, youth center, school, and fire station. The majority of boilers and furnaces are more than 10 years old, with some residential units being original installations from the early 1980's. Approximately 25 new boilers have been installed in Anaktuvuk Pass with the past 10 years. Efficiency of units varies. 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. Of the existing 118 residences in the community, 99 are currently occupied. Several of the vacant units are little more than large shipping crates banded together that provided shelter for families at one time. Other units are the property of the Housing Authority and scheduled for improvements and repairs as funding is allocated by the Department of Housing and Urban Development. 100 percent of the occupied homes depend on diesel fuel for heating. Approximately 70% of the homes use a baseboard/boiler system with varying degrees of efficiency. Some pre-1980 boilers are still in use in older homes. 10% of the properties managed by the regional housing authority have installed high efficiency boilers combined with weatherization efforts to reduce heating oil consumption. Remaining homes use one or more standalone heaters. Since the majority of homes are not energy efficient, many also utilize electric heaters in bedrooms and other areas during the long winter months. North Slope Borough Power and Light operates the local electric utility. Electricity is generated using diesel fuel and transmitted to properties via above -ground transmission lines. The rate schedule for use between 1 and 600 kilowatts (kW) is 15 cents per kW hour; use over 600 kW is 35 cents per kW hour. The community has a 2,400/4,160 Volt Distribution System with a 3,135 kW generation capacity. Anaktuvuk Pass residents receive a power cost equalization subsidy. Recognizing the benefit of waste heat recovery, the North Slope Borough has made attempts in many communities to utilize this resource. In Anaktuvuk Pass, the NSB has captured waste heat from the Power Plant for use in the Public Works building that houses maintenance, roads, sanitation, and other personnel. Heat recovery is also being utilized at the Fire Station for the apparatus bays. The addition of geothermal space heating in combination with additional waste heat recovery efforts can have a significant impact on a community that is totally isolated, relying solely on air transport of fuel and all other supplies. Even a small 1 % reduction in annual heating fuel consumption translates to more than $50,000 when air charter and other factors are considered. Based 2010 North Slope Borough Census and Economic Profile data, 34% of the labor force are unemployed and another 48% are underemployed. This is in sharp contrast to the Department of AEA 12-001 Grant Application Page 8 of 63 7/1 /2011 reampA AUTHORITY Renewable Energy Fund Grant Application Round 5 Labor information which is based largely on those individual that continue to file Unemployment Insurance claims. Thus, a reduction in expense required to heat homes in Anaktuvuk Pass could result in a life changing situation for a family already suffering financial problems. 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. The community of Anaktuvuk Pass is located on the divide between the Anaktuvuk and John Rivers in the central Brooks Range and the last remaining settlement of the Nunamiut (inland northern Inupiat Eskimo). The 2010 census indicates the permanent resident population at 234. The non-resident populations of another 20-30 individuals that routinely live in the community during extended periods include teachers, rotational police officers, operators and mechanics of public works facilities, and other specialty positions. In 1938, several Nunamiut families left the coast and returned to the mountains at Killik River and Chandler Lake. In 1949, the Chandler Lake group moved to Anaktuvuk Pass ("the place of caribou droppings"), where they were later joined by the Killik River group. This settlement attracted Nunamiut from other locations, and villagers today lead a more sedentary lifestyle than earlier nomadic times. The city was incorporated in 1959. Anaktuvuk Pass is a Nunamiut Eskimo community dependent upon subsistence activities. Economic and employment opportunities are limited in Anaktuvuk Pass, due to its isolation. Hunting and trapping for the sale of skins, guiding hunters, or making traditional Caribou skin masks or clothing provides income. Some residents have seasonal employment outside the community. Caribou is the primary source of meat; other subsistence foods include trout, grayling, moose, sheep, brown bear, ptarmigan, and water fowl. The North Slope Borough provides all utilities. There are two central wells in Anaktuvuk Pass, including a treated watering point at Nunamiut School. There are 101 identified residences in the community of more than 324 individuals. This includes residences that are reserved for the 12 non-resident teachers, rotational police officers, and other properties owned or leased to deliver technical and professional services. Many homes have piped water and sewer service, though many continue to receive water delivery by truck to holding tanks. A few residents haul their own water. Homes in Anaktuvuk Pass currently rely on heating by diesel heating oil. Emergency medical service is provided in Anaktuvuk Pass by local volunteer fire department members and a community health aide. Medical problems and emergencies must be relayed by telephone or other communication means to Fairbanks or other locations for assistance. Operation of the telephone system requires electricity. Reliable telephone service requires reliable electric service. The heaviest consumers of power in villages are the North Slope Borough water and sewer facilities. Additionally, 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. Anaktuvuk Pass is subject to long periods of darkness. Reliable electric service is essential for operation of home lighting, streetlights and security lighting. Isolated periods of blowing snows in the mountain passes combined with sub -zero temperatures can result in interruptions to fuel delivery within the community until roads can be cleared and service restored. Residents and AEA 12-001 Grant Application Page 9 of 63 7/1/2011 /S"�ALASHKA ENERGY AUTORTY Renewable Energy Fund Grant Application Round 5 facilities have utilized stand-by generators, electricity, and other system in these urgent situations. Costs in Anaktuvuk Pass are high, especially for fuel. Barges may service coastal communities, but that is not an option for inland Anaktuvuk Pass. Currently, it receives all fuel delivery by smaller planes capable of landing on the community runway. At present, much of the heating fuel is produced in Fairbanks, trucked to Prudhoe Bay, and then flown into Anaktuvuk Pass. While the community is within 90 miles of the TransAlaska Pipeline, it makes one of the highest costs for fuel in the state. Anaktuvuk Pass's water supply is provided by a well approximately 100 feet below the surface and that geotechnical information and exploratory wells in a few other locations of the Brooks Range indicate a potential geothermal resource might be available. This Reconnaissance study is requested to determine if geothermal, possibly combined with additional waste heat recovery efforts could provide the community of Anaktuvuk Pass with a residential space heat source to reduce dependence on diesel. 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 The North Slope Borough is proposing a ground source geothermal heat pump system that consists of approximately 21,000 feet of buried tubing to produce a heat source of 250,000 Btu per hour based on one ton heat capacity per 1,000 feet of buried tubing. The geo-thermally heated fluid will be combined with an additional 250,000 Btu per hour of waste heat from the existing electric power plant and from the waste water treatment process facility. The geothermal ground source fluid combined with waste heat fluids will increase the system efficiency by increasing the temperature of fluid flowing to the heat exchanger. A centrally located heat exchanger will utilize the combined fluids to produce warmer fluids piped to buildings for district heating. Ground source tubing will be buried in loops in a 4,000 foot long trench, 3-4 feet wide by 12-15 feet deep. The total area of land required for the trench is 300 feet wide by 600 feet long, or 4.2 acres. The energy produced from a geothermal system depends on the temperature and amount of flow of geothermal fluid being utilized and the temperature drop of the geothermal fluid within the system. As the resource has not yet been determined in detail, it is not feasible at this time to predict what the optimum installed capacity will be. The estimate of geothermal energy is based on one ton of heat capacity per 1,000 feet of buried tubing. The anticipated capacity factor of the resource is expected to exceed 90%. AEA 12-001 Grant Application Page 10 of 63 7/1/2011 r4ZIp ALASKA Renewable Energy Fund ENERGY AUTHORITY Grant Application Round 5 Heat produced from this process would be delivered to as many buildings as possible in the form of 100 to 120 °F warm glycol/water via an insulated piping system to the buildings and used in hydronic heat systems. Metering of the heat will be determined during the reconnaissance phase. The reconnaissance study will determine if a resource is available by completing an analysis of the viability and capacity of the potential geothermal resource in the community. This analysis will also determine the economic feasibility for the system. The study will then address the method of integration into the current system to establish economic payback for the system. With the community boundaries known, tubing loops would be installed in trenches within the current utility right-of-ways, platted by the North Slope Borough. Since the existing utility right of way is already platted, land ownership will not be an issue. Within the community boundaries, no major permitting or environmental issues are anticipated. During performance of the Reconnaissance work, potential landownership, permitting, and environmental issues may be identified. If issues are identified, they would be investigated further in future project phases 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 North Slope Borough has substantial land in the villages. The municipality is working with the native regional corporation which has subsurface rights to native lands within the Anaktuvuk Pass area. During performance of this Reconnaissance study, the North Slope Borough and its project partners will involve local stakeholders, as well as potential land ownership issues surrounding any energy resource AEA 12-001Grant Application Page 11 of 63 7/1/2011 /Sw:)�ALASKA Renewable Energy Fund ENERGY AUTHORITY Grant Application Round 5 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 No permits are required for this phase 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 Anaktuvuk Pass is situated at approximately 2,200 feet elevation in the Endicott Mountains of the Brooks Range. The community lies within the divide between the Anaktuvuk and John Rivers and is the last remaining settlement of the Nunamuit. The region has also been identified as the Gates of the Arctic National Park and Preserve, which has become a popular site for hunters from around the world. There are no known threatened or endangered species that reside in the area. As a community that must rely heavily on subsistence for both cultural identify and survival, the migratory patterns of caribou are critical to meet basic food needs. Acquiring subsistence resources has become increasingly problematic as federal enforcement in the Gates of the Arctic National Park and Preserve limits access to established trails. Expansion of small aircraft usage during the brief summer as a result of guides taking non- residents on hunting excursions has also impacted subsistence resource harvests. The community encompasses approximately 4.8 square miles of land and 0.1 square mile of water in a broad mountain valley. The valley floor is covered with glacial till. Soils are typically sandy, with a seasonal thaw extending three to four feet deep. Permafrost is estimated to be 1,000 feet deep. The area is influenced by a continental climate. Summers are cool with temperatures around 50°F. Winters are cold, with an average temperature in January of -14°F. Precipitation averages 11 inches, with snowfall of 63 inches per year. In Anaktuvuk Pass, as in other North Slope villages, accurate information regarding the status of title for individual lots is not always available. There are Native allotment applications within lands selected by the Nunamiut Corporation; however, the closest is approximately three miles southeast. Nunamiut Corporation has the right to select 92,160 acres of land in the Anaktuvuk Pass area; with 82,017 acres patented to the corporation to date. Land selections and conveyances are still incomplete, with 7,032 acres conveyed and 3,111 acres remaining to be selected. The corporation must convey up to 1,280 acres of land to the City of Anaktuvuk Pass. Arctic Slope Regional Corporation (ASRC) owns the subsurface rights to Nunamiut Corporation lands, as well as additional lands in the Anaktuvuk Pass area. AEA 12-001Grant Application Page 12 of 63 7/1/2011 ,© ALASKA Renewable Energy Fund 401E) ENERGY AUTHORITY Grant Application Round 5 The federal government owns approximately 11 million acres that surround the community; the National Park Service manages the land in Gates of the Arctic National Park and Preserve. Environmental Approach. This phase of the project involves performance of a Reconnaissance Study about potential geothermal resource opportunities within the vicinity of Anaktuvuk Pass. Since the community's drinking water source is provided by a well, there is a known underground flow. While no geothermal exploration has been completed within the valley, one site southwest of Anaktuvuk Pass recorded measurements more than 30 years ago. If a potential resource is identified, the Reconnaissance Study would identify environmental issues requiring investigation in subsequent project phases. 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 of proposed renewable energy system This application is for performance of a Reconnaissance study to determine if geothermal resources exist in Anaktuvuk Pass and the potential of those resources in addressing some of the space heating needs in the community, possibly incorporating additional waste heat recovery efforts. The North Slope Borough is requesting $169,960 for the performance of this work from the Alaska Energy Authority. The North Slope Borough proposes to provide 10% cash match for this phase of the project. The estimated capital costs for this project are approximately $2,057,000, with approximately $250,000 for development. These estimates would need to be adjusted based on information obtained during Reconnaissance and future feasibility efforts. 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 North Slope Borough will facilitate performance of a Reconnaissance study utilizing one or more contractors that can provided the technical and specialty expertise related to potential geothermal resource identification and analysis, as well as other key milestones involves in this phase of the project. Pending successful identification of a geothermal resource, the North Slope Borough would continue AEA 12-001 Grant Application Page 13 of 63 7/1/2011 /liu ALASKA Renewable Energy Fund © ENERGY AUTWAITY Grant Application Round 5 work to define operational and maintenance costs associated with project development. Progress reports and financial reporting will be handled by NSB program managers and staff. A rough estimate of potential O&M for the new system is $25,000, some of which may be offset by a reduction in existing diesel fuel usage and other services. 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 The North Slope Borough is the owner and operator of the utility in this community. Purchases of power will be residents and commercial entities residing in the community of Anaktuvuk Pass. Power Purchase/Sale is not required. The potential rate of return if a successful power source is identified has been discussed previously. 4.4.4 Project Cost Worksheet Complete the cost worksheet form which provides summary information that will be considered in evaluating the project. 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. 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 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 project As noted previously, the addition of renewal energy can have a significant impact on the lives of people, especially in totally isolated communities like Anaktuvuk Pass, which rely solely on air transport of fuel and other supplies. Even a small reduction in annual heating fuel consumption can translate to a significant financial benefit to a family already struggling with unemployment or underemployment. 2010 North Slope Borough Census and Economic Profile data indicate that 34% of the labor force in Anaktuvuk Pass are unemployed and another 48% are underemployed (seasonable or less than 40 hours per week). The ability to reduce the high cost of diesel fuel consumption for home heating would enable residents to redirect income to improving other living conditions. AEA 12-001 Grant Application Page 14 of 63 7/1 /2011 I ALASKA Renewable Energy Fund � ENERGY AUTHORITY Grant Application Round 5 A rough estimate for annual fuel displacement based on a functional geothermal system would be approximately 22,000 gallons per year or $165,000. There are a number of associated costs that would require further analysis in subsequent phases to document. These include the costs, risks, and associated factors to transport fuels from Fairbanks and Prudhoe Bay to Anaktuvuk Pass. The transportation process itself involves consumption of fuel for transport trucks, aircraft, and other support operations. Reducing these demands translate to a benefit in use of fossil fuels and the associated contamination. Costs in Anaktuvuk Pass are high, especially for fuel. Barges may service coastal communities, but that is not an option for inland Anaktuvuk Pass that must currently receive all fuel by smaller planes capable of landing on the community runway. At present, much of the heating fuel is produced in Fairbanks, trucked to Prudhoe Bay, and then flown into Anaktuvuk Pass. While the community is within 90 miles of the TransAlaska Pipeline, it makes one of the highest costs for fuel in the state. Additionally, decreased demand for power generation for space heating would translate to a reduction of diesel fuel consumption by the power plant and release of additional contaminates caused by emissions. The ability to identify specific costs and revenue from this project would be defined in the feasibility phase following resource identification and associated issues. Since the North Slope Borough is the coordinating entity for procurement and delivery of fuel to Anaktuvuk Pass, any reduction in the annual consumption results in a financial benefit that could support operation and maintenance costs of a geothermal system. Until more data is available and analysis completed, many factors remain unknown. An additional benefit to the State of Alaska is further collection and analysis of geothermal data. As noted in the Renewable Energy Atlas of Alaska (AEA, 2011), Anaktuvuk Pass is near one of the four distinct geothermal resource regions. Unfortunately, no data has been collected in the Anaktuvuk Pass valley to identify potential geothermal energy resources. While some assumptions might be drawn from data collected at Prudhoe Bay or other sites, these are hundreds of miles from Anaktuvuk Pass. Located within the central Brooks Range, collection and analysis of data could provide Alaska another valuable resource as renewable energy exploration continues in the state. SECTION f- 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 geothermal system would be fully integrated into the North Slope Borough owned and operated utility system. The proposed plan would be annual operations and maintenance costs are incorporated into the North Slope Borough budget, ideally offset in whole or part by a reduction in the consumption of diesel fuel. Significant capital upgrades would be identified in the North Slope Borough Capital Improvements Six -Year Plan. The North Slope Borough has existing infrastructure to support this project and is inherently sustainable. Operational issues that could arise are in integrating between geothermal and existing diesel systems, as well as the cost of training current Power Plant Operators and other personnel on geothermal heat use. AEA 12-001 Grant Application Page 15 of 63 7/1 /2011 rmp ALASKAENERGY AUTHORITY Renewable Energy Fund Grant Application Round 5 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. Anticipated operational and maintenance costs would be defined depending on the type and level of geothermal resource available and the capability of the resource to meet community needs. Operation and maintenance costs would be off -set by energy sales in the village, as well as maximizing other available sources of revenue. Power Plant operators will be trained to collect data and 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 has conducted some internal planning and discussion about renewable energy resources for Anaktuvuk Pass. A feasibility study funded by the North Slope Borough for wind generation in Anaktuvuk Pass is expected to be finalized in September. Data indicates that wind power is not a feasible option for providing renewable energy resource needs. Recognizing community water in Anaktuvuk Pass is provided year round by underground well, the North Slope Borough desires to evaluate the capability of geothermal resources that possibly in combination with additional waste heat recovery to reduce demand for fossil fuels. While there is no geothermal in various areas of the Brooks Range, which is a fault zone, no data is available for Anaktuvuk Pass area. SECTION l- LOCAL SUPORT 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 power and energy in the Borough. They own all local utilities, so a resolution from the Borough Board of Directors is included here as Attachment G. 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 — GrantBudget5.doc Provide a narrative summary regarding funding sources and your financial commitment to the project. Recognizing the importance of renewable energy resources especially in remote Alaska, the North Slope Borough funded performance of a feasibility study for wind power generation in AEA 12-001Grant Application Page 16 of 63 7/1/2011 r:) ALASKAENERGY AUTHORITY Renewable Energy Fund Grant Application Round 5 Anaktuvuk Pass. Unfortunately, data does not identify the community as a strong candidate for wind power. The North Slope Borough is seeking assistance to fund the Reconnaissance study in the amount of $169,960 from the Alaska Energy Authority recognizing geothermal may provide an alternative for the isolated community of Anaktuvuk Pass. The North Slope Borough proposes to provide an in-house project management team and a 10% cash match. Additionally, the North Slope Borough recognizes there will be significant financial contribution through costs associated with communication and involvement of the project management team throughout the process. Grant funds will be used to hire engineering and other expertise to gather data, identify and analyze potential energy resources, review land use, perform preliminary design analysis and costs, market analysis, and simple economic analysis to enable completion of a final report and recommendations.

But, the viability of wind power in a remote community is primarily dependent on the cost of fuel for electricity generation. Given the very high cost of diesel fuel in Anaktuvuk Pass, the economics of wind development may well be favorable.

In all three circumstances, the cause appears to be icing conditions. During the first data loss event, however, the anemometers were non- functional yet the wine vane returned data and the RH sensor indicated lower than expected humidity for an icing event. Forthe other two data loss events, loss of wind vane data appears to confirm icing, but a non-functional RH sensor (due to voRage drawdown of the iPack battery from lack of sunlight) does not allow confirmation of the high humidity typical of rime icing conditions. Given the very cold temperatures during the three data loss periods and the location of Anaktuvuk Pass well away from the coast, the icing losses are undoubtedly due to hoarfrost conditions and not rime icing.

The discrepancy in mean wind speed between the 30 m A and the 30 m B anemometer is due to the placement of the of the 30 m A anemometer at 179° True. With frequent NNE winds, the 30 m A anemometer experienced some tower shadowing effects. Note that it can be problematic analyzing wind data with concentrated data loss, such as occurred in Anaktuvuk Pass during a few of the winter months. To correct this problem, synthetic data was inserted in the data gaps to create a more realistic wind speed data profile.

Extreme wind analysis indicates a very low probability of extreme wind events. This may be particular climactic aspects of Anaktuvuk Pass which include considerable distance from the windy sea coast and lack of exposure to Gulf of Alaska storm winds. Industry standard reference of extreme wind is the 50 year,l0-minute average probable wind speed, referred to as Vrd. For Anaktuvuk Pass, this calculates to 20.2 m/s, well below the 37.5 m/s threshold of International Electrotechnical Commission (IEC) 61400-1, 3`d edition criteria fora Class III site.

At most stations, AWOS/ASOS data has been collected for twenty-five or more years. Anaktuvuk Pass Airport (ICAO station identifier. PAKP) AWOS was installed in 1981. The AEA report documents data from AWOS sensor, which is 9 meters above ground level. To compare this 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 0.14, which is more conservative than the 0.175 power law exponent calculated from met tower data and more typical of large open areas in Alaska. 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 data. This would account for the higher wind class prediction of the met tower (Class 2) over the airport data (Class 1).
