3.3 Project Resources
Describe the personnel, contractors, accounting or bookkeeping personnel or firms, equipment,
and services you will use to accomplish the project. Include any partnerships or commitments
with other entities you have or anticipate will be needed to complete your project. Describe any
existing contracts and the selection process you may use for major equipment purchases or
contracts. Include brief resumes and references for known, key personnel, contractors, and
suppliers as an attachment to your application.
The 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 complete the design for the wind turbine foundations. The North Slope Borough will
subcontract for the construction of the foundations and the contracted ME firm will manage that
construction
In the construction phase, based on the recommendation of the conceptual design report it is
foreseen that three Vesta V27 will be placed at the second site that was investigated. The V27
is pitch -regulated, has a synchronous (induction) generator, active yaw control, a 27 meter
diameter rotor, is rated at 225 kW power output, and is available with 30, 40, or 50 meter tubular
steel towers. The site identified is Kaktovik Site 2 located at 70007'30.71" north latitude,
143039'44.91" west longitude, at an elevation of approximately 50 feet MSL. The site is located
closer to the community and water source lake, and is also on KIC lands.
3.4 Project Communications
Discuss how you plan to monitor the project and keep the Authority informed of the status.
Please provide an alternative contact person and their contact information.
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. Weekly
and monthly project coordination meetings will be held with the project team to track progress
and address issues as they arise.
3.5 Project Risk
Discuss ❑ctential problems and how you would address them.
Logistical and construction activities and weather all contain significant risks. The North Slope
Borough routinely purchases Builder's Risk insurance to mitigate its exposure to these risks. In
addition to outside insurance, the experienced team of North Slope Borough and contracted
A&E firms with projects much like this one is similar circumstances reduces the risk.
Logistics and weather are routinely issues in rural Alaska. The North Slope Borough has
extensive experience working in rural Alaska under these conditions. Crucial to successful
completion of projects in these environments are advanced planning and flexibility in timing.

NSB's existing Kaktovik power plant is located on Fourth Street South on the southern outskirts of
Kaktovik. The power plant is owned and maintained by the NSB. The plant, built in 2000, consists
of an 82-foot by 60-foot insulated pre-engineered steel structure. The power plant contains
generator appurtenances, day tanks, an office, bathroom, storage area, a maintenance area,
radiator room and switchgear. The Power Plant does not have boilers; the building utilizes waste
heat only. From the power plant two feeders serve the (2) 1000kVA transformers that feed north
and south distribution loops for the village The building is founded on a passively refrigerated,
insulated slab -on -grade type foundation.
The power plant contains the following Caterpillar generator sets:
(2) Caterpillar 910 kW 3512 diesel generator - (Last Major Overhaul in 2012)
(2) Caterpillar 450 kW 3508 diesel generator - (Last Major Overhauled in 2012)
2,720 kW Total Generation Capacity
Currently there are four generators installed with space available for two additional generators. An
electric boiler could be placed within the space allocated for one of the future generators. This
would still allow for one future generator should the village power requirements grow requiring a
fifth generator.
The existing power plant switchgear is rated 4000A, 277/480V, 3-Phase, 4-Wire consisting of six
(6) generator sections, a master control section, and two (2) distribution sections. Four (4) of the
six (6) generator sections contain generator breakers and controls (Caterpillar EMCP II) and the
remaining two (2) generator sections are spared for future use containing only generator breakers
without controls. The master section contains the Switchgear PLC, various controls, gauges and
alarm indicators as well as a totalizing meter, east and west feeder meters and the station service
meter. Distribution Section #1 contains the east and west feeder breakers as well as provisions
for a future 1600A frame feeder breaker. Distribution Section #2 contains the Station Service
feeder breaker as well as two additional spare feeder breakers. The switchgear was designed and
manufactured by Controlled Power Inc. out of Bothell, WA for NC Machinery (generator supplier).
The Power Plant is also scheduled for major upgrades and/or replacement, with design beginning
as early as 2014. This work would include a new Paralleling Switchgear with a new Allen
Bradley PLC and Woodward EasyGen Generator Control system.
According to the historic Alaska Energy Authority records (AEA) Power Cost Equalization (PCE)
program, the power plant generated a total of 4,806,050 kWh in Fiscal Year 2012 with an average
efficiency of 13.25 kWh per gallon of diesel consumed.
A new wind turbine installation would require the use of one of the existing spare switchgear
generator sections. The existing feeder breakers in one of the sections could be utilized to
connect the new wind turbines to the switchgear. Only a trip unit would need to be replaced within
the existing breaker as the frame size is adequate for the proposed wind turbine capacity,
however, it may be desired to replace the existing breaker with a new GE PowerBreak II model
per current NSB standards. The section would also need to be equipped with a new controller that
would be connected to the existing Switchgear PLC to allow for proper load sharing between the
new wind turbines and the existing diesel generators. Appendix A shows
the existing Power Plant One -Line Diagram with the addition of a typical Wind Turbine
installation.
The proposed location for the new wind turbines will require a new overhead, 2400/4160V, 3-
Phase, 4-Wire distribution line as well as two (2) 750kVA pad mounted transformers, one at the
wind farm and the other at the power plant, to step the voltage up and back down prior to

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 causes 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 lookout for hazards such as deep snow or in the
extreme case, polar bears
Residents of Kaktovik rely on a subsistence lifestyle where food is gathered and harvested, then
stored for later use. Refrigeration is essential for the extended storage of perishable food.
Reliable electric service is essential for proper freezer storage of food during summer months.
The North Slope Borough expects 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 technology description
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
have the choice of diesel fuel or wind energy.
The recommendation for Kaktovik is the installation of three Vestas V27 turbines at Kaktovik Site
2 for a total cumulative generation capacity of 675 kW. This turbine configuration has a 675 kW
rated generation capacity, which exceeds the current average electrical load for Kaktovik. The
economic evaluation above assumes that the turbine operates at 80% turbine availability without
exceeding rated energy output levels. However, for better system performance, the turbines
should be pitch controlled to modulate energy output to a level that provides medium penetration
to the Kaktovik grid and adequate excess energy to meet recovered heat demands.
Optimum installed Capacity
The recommended system consists of three Vesta V27 turbines to operate with the existing diesel
plant as a wind -diesel hybrid power system. Installed wind power capacity of this configuration
would be 675kW.

Kaktovik lies on the north shore of Barter Island, between the Okpilak and Jago Rivers on the
Beaufort Sea coast. It is within 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 OF. Precipitation is light, averaging 5 inches, with snowfall averaging 20 inches annually.
Kaktovik, Alaska is located on the northern coast of Alaska and is underlain by continuous stable
permafrost. There is one known threatened or endangered species, 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 (ADNR), Office of Coastal and Ocean Management
(OC&OM). 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.

4.4.5 Impact on Rates
Briefly explain what if any effect your project will have on electrical rates in the proposed benefit
area. If the is for a PCE eligible utility please discus what the expected impact would be for both
pre and post PCE.
For PCE eligible sales, about 5% of the benefit of reduced electric costs is passed on to
ratepayers, with the remaining 95% accruing to State of Alaska thru reduced PCE credits to end
users. For non-PCE eligible sales, end users would receive the entire benefit of reduced power
costs from a wind project. Savings for non-PCE customers can be substantial and this should
result in a positive economic impact for the community.
Offset of heating oil use with excess wind energy is another direct benefit. Depending on system
design, heating oil offset can be for commercial end users, residential end users, or both.
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 (gallons and dollars) 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
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.
5.1.1 Public Benefit for Projects with Private Sector Sales

DRAFT Kaktovik Wind -Diesel Project
North Slope Borough Concept Design Report
F>!F>1��Z�iL�1►J
The proposed wind turbine project is located near the village of Kaktovik on Barter Island.
Kaktovik is located on the northern shore of Barter Island facing the Kaktovik Lagoon and the
Beaufort Sea. The village is on the northern edge of the Arctic National Wildlife Refuge
(ANWR), 640 miles northeast of Anchorage and 118 air miles southeast of Prudhoe Bay.
Kaktovik is situated at approximately 70°7'03.56" North Latitude and-143°37'56.44 West
Longitude (Sec. 18, T09N, R033E, Umiat Meridian). There are no roads leading to Kaktovik, its
only access is by flight or by barge service. (See Figure 2). The barge service makes a trip once
a year from Seattle leaving June and arriving in Kaktovik sometime in August. Year-round
aircraft access is available via an existing 4,820-foot long by 100-foot wide gravel runway in
Kaktovik. Currently a new runway is under construction to replace the existing, which will
consist of a 4500-foot long by 100-foot wide gravel runway. The runway is owned and
maintained by the North Slope Borough.
Kaktovik has a population of 239 residents (2010 U.S. Census Population), with 88.7% being
Alaska Native or American Indian. The local residents depend heavily on the subsistence
harvest of marine and terrestrial mammals. Primary employment in Kaktovik is with the North
Slope Borough, North Slope Borough School District and Kaktovik Inupiat Corporation.

connect the new wind turbines to the switchgear. Only a trip unit would need to be replaced
within the existing breaker as the frame size is adequate for the proposed wind turbine
capacity, however, it may be desired to replace the existing breaker with a new GE PowerBreak
II model per current NSB standards. The section would also need to be equipped with a new
controller that would be connected to the existing Switchgear PLC to allow for proper load
sharing between the new wind turbines and the existing diesel generators. Appendix A shows
the existing Power Plant One -Line Diagram with the addition of a typical Wind Turbine
installation.
The proposed location for the new wind turbines will require a new overhead, 2400/4160V, 3-
Phase, 4-Wire distribution line as well as two (2) 750kVA pad mounted transformers, one at the
wind farm and the other at the power plant, to step the voltage up and back down prior to
tying into the existing power plant switchgear.
According to the historic Alaska Energy Authority records (AEA) Power Cost Equalization (PCE)
program, the power plant generated a total of 4,806,050 kWh in Fiscal Year 2012 with an
average efficiency of 13.25 kWh per gallon of diesel consumed
Waste Heat. Waste heat is captured from all four generators via the engine jacket water.
Exhaust stack heat recovery is not being utilized at this time. The engine jacket water rejects
heat to a waste heat plate and frame heat exchanger located in the power plant radiator
plenum. Waste heat from the engines is distributed to the various NSB buildings via two
centrifugal pumps connected to a waste heat pipe manifold.
Two waste heat loops are connected to the manifold. The first loop is buried and connects the
new power plant to the old power plant with a tee off to the Utilities -School District Warehouse
(USDW) and Public Works Vehicle Maintenance Shop (VMS) buildings. The second loop is an
above -ground loop that supplies the Water Treatment Plant, Health Clinic, and Fire Station. All
facilities are operated by the NSB. Both loops are constructed with well -insulated arctic pipe
which results in minimal heat loss to the atmosphere or ground.
The engine jacket water heat recovery system on average generates approximately 1.1 million
BTUs per hour of useable energy. As presently constructed the village -wide waste heat
recovery system is able to absorb all of this heat for most of the year. Only during a few
summer months is more waste heat generated than can be used. During this period the engine
radiators are used to cool the engines; the rest of the year the waste heat system acts as the
engine radiators.
If wind power is generated in the village an electric boiler secondary controller would be used
to store the energy that cannot be absorbed instantaneously by the electric power grid. The
electric boiler would be located in the power plant or in a nearby module and would connect to
the waste heat loop downstream of the jacket water heat exchangers. The new electric boiler
will be fed from a feeder breaker from the existing switchgear Distribution Section #2. The
existing spare 800A frame breaker should be adequate for the new electric boiler. If a new
radiator is installed for excess waste heat rejection, the associated motor can be powered from
the existing power plant Panel 'AA', similar to the existing radiators.

3.0 WIND DATA ACQUISITION AND MODELING
3.1 DATA ACQUISITION
On June 26, 2009 NSB installed a 30 meter tall meteorological (met) tower located 650 meters
(2,100 feet) south of the village boundary near the sewage treatment plant (See Sheet G1.03,
Appendix A). The met tower location is owned by Kaktovik Inupiat Corporation (KIC). The met
tower was equipped with three separate anemometers, a wind vane, a temperature sensor, a
relative humidity sensor, and a voltmeter. Two of the anemometers were installed 30 meters
above ground level and one was installed 20 meters above ground level. The tower collected
wind data at this location until October 2, 2009 after which the data card was lost and all data
from October 2 to November 13 were lost with it. Following the loss of the data card,
December experienced a frequent occurrence of icing events which rendered the anemometers
and wind vane inoperable for much of the month. Early January 2010 resulted in both the 30
meter level anemometers breaking off the tower and they were not replaced until March 3,
2010.
The collected data was stored on a data logger mounted to the base of the met tower. Stored
data was downloaded every 3 to 6 months during site visits to inspect the equipment. The
quality of the data was poor with only 62 to 71 percent data return from the anemometers and
wind vane. NSB contracted with V3 Energy to analyze the collected wind and temperature data
and calculate wind speed, air density, prevailing wind direction, wind shear, and other factors
effecting wind energy production. The data collection process and modeling results are further
defined in V3 Energy's August 2013 Kaktovik Wind -Diesel Analysis (Appendix B).

thin organic mat (1 to 2 feet) with ice -rich fine-grained permafrost soils and the potential for
saturated sands and fine gravel as deeper depths - typical of the Barter Island area. Bedrock is
not expected. The wind tower foundation type at this site would likely be a pile group (6 or 8 in
a hexagon or octagon layout) of passively refrigerated slurry -back steel piles in augured holes,
with a steel or concrete pile cap to transfer loads from the tower base to the piling. Access to
the site would be along an existing trail that will be upgraded during the airport project, and
then a new access road across virgin tundra to the site. Easements with KIC would be required.
Wind modeling suggests a potential Class 5/6 wind resource at this site. See V3 Energy's August
2013 Kaktovik Wind -Diesel Analysis (Appendix B) for wind modeling information. The relatively
high potential wind resource at this site makes it a desirable wind farm location.

Figure 8: Kaktovik Site 3
At the time of the site investigation, Kaktovik Site 2 appears to be the most promising
alternative for wind farm construction due to the higher exposure, lower environmental
impacts, close proximity to the power plant and reasonably good access. Alternatives 1, 2, and
3 presented in Section 5.0 below include wind turbine options installed at this site. The
extrapolated wind data from the Kaktovik Met Tower suggests a potential Class 5/6 wind
resource at Kaktovik Site 2 which is sufficient for power generation. See V3 Energy's report in
Appendix B for wind modeling information.
5.0 WIND TURBINE SYSTEM ALTERNATIVES
5.1 KAKTOVIK WIND TURBINE ANALYSIS
The following 3 turbine alternatives were selected for evaluation at Site 2: the Aeronautica 29,
Northern Power 100 Arctic, and Vestas V27. The most significant factor with respect to the
choice of wind turbines in Kaktovik is the height limitation dictated by the proximity of the
prospective wind turbine site to the new airport. Obstruction heights are governed by FAR Part
77, Objects Affecting Navigable Airspace, and are subject to FAA review and approval to
determine if the obstruction adversely impacts the national airspace system. These turbines
were selected because they are small enough to meet the FAA height limitations and large
enough to meet the power load of Kaktovik. See Table 2 for the comparative size. All
configurations are classified as medium wind -diesel penetration systems having a goal to offset
20% to 50% of the community's energy demand with wind power. A medium penetration
system provides a balance between the amount of energy provided and the complexity of the
wind generation and integration systems.

5.1.2 Northern Power 100 Arctic
The second turbine configuration consists of seven Northern
Power 100 Arctic (NP100s) turbines. The NP100's are
manufactured by Northern Power Systems in Barre, Vermont.
The NP100 is a 30-meter high, 100 kW, permanent magnet,
synchronous, direct drive wind power generator, with a 21-
meter rotor diameter, and is the most represented village scale
wind turbine in Alaska with a significant number of installations
in the Yukon-Kuskokwim Delta region of the state as well as five
turbines in Gambell and Savoonga on St. Lawrence Island.
Each turbine is equipped with active yaw control, but does not
have blade pitch control capability. The seven proposed
Northern Power100 Arctic generators have a maximum
cumulative power generation output of 700 kW at a wind
speed of approximately 32.4 mph.
K
5.1.3 Vestas V27 Figure 10: Northern Power 100
The third turbine option consists of three Vestas V27 turbines. Vestas turbines were originally
manufactured in Denmark; presently they are manufactured
under license in India. The V27 is pitch regulated, has a
synchronous (induction) generator, active yaw control, a 27
meter diameter rotor, 225 kW power output, and is available
with 30, 40, or 50 meter tubular towers.
St. Paul Island, Alaska currently operates the V27 turbine, and
they are presently available to Alaska as a remanufactured unit
from Hauls Power Systems in San Leandro, California.
5.2 ALTERNATIVE 1 - THREE AW29-225 TURBINES INSTALLED
AT KAKTOVIK SITE 2
This alternative proposes installation of three AW29-225 turbines
at Kaktovik Site 2 for a total cumulative generation capacity of
675 kW. The project includes construction of approximately
2,500 feet of 16-foot wide gravel access trail and three
approximate 1,000 square foot circular gravel pads at the wind

tower locations. The proposed trail and wind tower pads would
be insulated with rigid insulation and are anticipated to be 4 feet thick and consist of locally
available sand and gravel compacted to 90% maximum density. The drivable surface of the
embankment is constructed with 6-inches of crushed aggregate surface course. The turbines

6.0 ECONOMIC EVALUATION
6.1 METHODOLOGY AND APPROACH
The Kaktovik Wind Diesel Analysis prepared by V3 Energy (Appendix B) includes an economic
analysis of the Kaktovik power generation system using the HOMER energy modeling software
for the turbine alternatives. The software was configured for a medium to high penetration
system with the first priority to meet the community's electrical demands and the second
priority to serve the recovered heat system through a secondary load controller (electric
boiler). The analysis considered an average diesel fuel price of $5.27 per gallon for the
projected 20-year project life. The modeling assumptions and results of V3's analysis are
presented in Appendix B.
V3 inserted the power generation and fuel consumption results from the HOMER modeling
into the economic modeling program developed by the Institute for Social and Economic
Research (ISER). AEA uses the ISER economic model as the standard approach for scoring
wind project design and construction grant applications. The ISER model considers the capital
cost of construction and annual cost of operating and maintaining the wind turbines and
weighs them against the benefit cost savings realized from the volume of displaced diesel fuel
required for power generation and heating public facilities. The analysis develops a
benefit/cost ratio that can be used to compare wind turbine alternatives. See V3's economic
analysis results in Appendix B.

frozen -back into the permafrost. The foundations are consistent with the preliminary
recommendations of the Geotechnical Review.
9.0 ENVIRONMENTAL REQUIREMENTS
9.1 HISTORIC AND ARCHAEOLOGICAL: ALASKA STATE HISTORIC PRESERVATION OFFICE
(SHPO)
Section 106 of the National Historic Preservation Act requires project proponents receiving
federal funds or requiring federal permits to consider the effects of their actions on properties
in or eligible for inclusion in the National Register of Historic Places. Compliance with Section
106 requires consultation with the State Historic Preservation Officer (SHPO) and the North
Slope Borough (NSB) Inupiat History, Language, and Culture (IHLC) Division if there is a potential
adverse effect to historic properties.
According to prior cultural resource assessments conducted in the vicinity of the project, there
are seven known cultural resources on Barter Island. None of the known resources are in the
immediate vicinity of any of the proposed site alternatives; however a field survey may be
needed to determine the potential for undiscovered sites to exist.
9.2 WETLANDS AND WATERS OF THE U.S.: U.S. ARMY CORPS OF ENGINEERS (USACE)
Section 404 of the Clean Water Act requires a permit for placement of fill in wetlands and
waters of the United States.
All of the undeveloped land on Barter Island is classified as wetland and is subject to USACE
jurisdiction. Nationwide Permit (NWP) 51 for Land Based Renewable Energy Generation
Facilities authorizes discharge of fill materials for wind tower construction if loss of wetlands
does not exceed one-half acre. The permit also covers utility lines, roads, and parking lots
within the wind generation facility. Submittal requirements for NWP 51 include a Pre -
Construction Notification. Access roads and transmission lines not within the facility and used
to connect the facility to existing infrastructure require separate permitting. NWP 12 (Utility
lines) and 14 (Linear transportation) may be used for this purpose if loss of wetlands does not
exceed one-half acre for each permit type.
The USACE recommends that wetlands delineations be completed within the designated
growing season for specific regions. Barter Island is located within Alaska's Arctic Coastal Plain
ecoregion, which has a growing season that begins on June 20th and ends on September 18th.
9.3 FEDERAL AVIATION ADMINISTRATION (FAA)
Based on preliminary review of the online Obstruction Evaluation/Airport Airspace Analysis
(OEAAA) tool, all sites under consideration exceed CFR Title 14 Part 77 Notice Criteria for slope
ratio. Part 77 regulations require an airspace study and filing Form 7460-1 for the proposed
tower locations to determine the impacts to the national airspace system. Preliminary analysis

9.9 SUBSISTENCE ACTIVITIES
Kaktovik Wind -Diesel Project
Concept Design Report
Coordination with Kaktovik community members will be needed to ensure there is little to no
disruption of hunting and harvesting activities from wind farm development. Preliminary
discussions with community members indicate that Site 3 is used for subsistence waterfowl
hunting. The final location of the towers will be coordinated with the community during design
to minimize impacts to subsistence activities.
9.10 AIR QUALITY
According to Alaska Administrative Code (AAC) 18 AAC 50, the community of Kaktovik is
considered a Class II area. As such, there are designated maximum allowable increases for
particulate matter 10 (PM-10) micrometers or less in size, nitrogen dioxide, and sulfur dioxide.
Activities in these areas must operate in such a way that they do not exceed listed air quality
controls for these compounds. The nature and extent of the proposed project is not likely to
increase emissions or contribute to a violation of an ambient air quality standard or cause a
maximum allowable increase for a Class II area.
9.11 NATIONAL ENVIRONMENTAL POLICY ACT REVIEW (NEPA)
An Environmental Review (ER) document will be required if federal funding is used for
construction of the wind turbine project. Similar to an Environmental Assessment (EA), an ER
will provide an assessment of potential environmental impacts and identify avoidance,
minimization, and mitigation measures. A Finding of No Significant Impact (FONSI)
determination by the funding agency will be needed.
9.12 ENVIRONMENTAL SUMMARY AND RECOMMENDATIONS
Table 5 below summarizes environmental data and permit requirements for development of
wind turbines on each site investigated.

10.0 CONCLUSIONS AND RECOMMENDATIONS
The high cost of diesel fuel and strong wind resource on Barter Island makes wind power an
attractive component of NSB's electrical power generation system for Kaktovik. The wind site
investigation and subsequent wind modeling analysis determined that Site 2 has a Class 5/6
wind resource and is well -suited for wind power generation. Economic evaluation of the
turbine alternatives presented in this report resulted in a preferred turbine configuration of
three Vestas V27 turbines installed at Site 2. The economic evaluation projected that this
preferred alternative will contribute to approximately 28% of yearly power production and will
offset approximately 37,136 gallons of fuel for power generation and 3,314 gallons of heating
oil per year. Wind power could provide approximately 2.8% of the energy needed for heat
recovery. Integration of the wind power into the diesel power plant will require a large
secondary load controller to prevent overloading the grid with excess energy and tripping the
generators offline.
The following actions are recommended to continue the progress of wind turbine development
in Kaktovik:
Recommendations
1. Conduct a bird hazard study.
2. Begin discussions with the Kaktovik Inupiat Corporation for site control and access rights to
Kaktovik Site 2.
3. Consult with Kaktovik community leaders to minimize the impacts to subsistence activities
from a wind project development at Site 2.
4. Proceed with permitting per the permitting recommendations in Section 9.
5. Once the site is confirmed, perform a site -specific geotechnical investigation of the proposed
turbine location.
6. Incorporate a secondary load controller and wind energy integration controls into the power
plant design.
7. If complications resulting from site control, permitting, or the geotechnical investigation
make development of Kaktovik Site 2 not feasible, relocate the proposed wind turbine
project to Site 1 and reinitiate the actions stated above.
8. Perform final design of the preferred alternative and apply for construction grant funds.
