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.)
The primary financial benefit from this project would be to determine whether the wind
resources are suited to provide power to the community and to prepare a conceptual design of
a wind facility.
Once constructed, this project could produce 163,987 kW annually. The possible displacement
of diesel fuel used for village power generation in Eek could be 13,632 gal/yr (assuming 80%
turbine availability). This project could save $48,800, the first year of operation (2014).
See the detailed project benefits in Section 5.0.
2.6 PROJECT BUDGET OVERVIEW

manage the project cash flow. (See Section 2 of the RFA or the Budget Form.)
1.Project scoping and contractor solicitation (September 1-September 15, 2011)
AVEC would select a contractor for the wind feasibility, geotechnical analysis, conceptual
design, and permitting immediately following AEA’s authorization to proceed.
2.Detailed resource assessment (September 15, 2011-October 31, 2012)
To initiate the Wind Resource Analysis before winter,AVEC would purchase (if necessary), ship,
and erect the met tower in September 2011. AVEC would immediately seek approvals from
permitting agencies, starting the process before the grant is awarded to ensure that the met
tower can be installed in the late fall. The earlier the met tower is collecting data, the earlier
AVEC would have the wind resource data to ascertain the suitability of use this renewable
resource. Monitoring of the met tower would continue until September, 2012, when the met
tower would be dismantled. The wind resource report would be drafted by the end of October,
2012.
3.Identification and resolution of land issues (September 15, 2011-June 1, 2012)
AVEC would work with the Iqfijouaq (Native) Corporation to obtain a letter of non objection for
the placement of the met tower and geotechnical work. Permanent site control to place
turbines, if feasible,would be negotiated.
4.Detailed analysis of current cost of energy and future market (February 1-March 30, 2012)
AVEC would draft a memorandum documenting the existing and future energy costs and
markets in Eek. The information would be based on AVEC records and community plans. A
community meeting would be held to determine future energy markets.
5.Detailed economic and financial analyses (June 1-August 30, 2012)
An economic and financial analysis, which examines potential final design and construction
costs, operating and maintenance costs, user rates, and other funding mechanisms,would be
developed.
6.Conceptual business & operations plan (June 1-October 31, 2012)
Draft business and operational plans would be developed working with the City of Eek and the
Eek Iqfijouaq Corporation. The conceptual plan would include draft recovered heat

AEA11-005 Grant Application Page 7 of 18 7/21/2010
An AVEC project manager would lead this project. It is likely that one of AVEC’s in-house
contractors would lead the work. The project manager would be responsible for:
Obtaining site control/access and permits for the installation of the met tower and
geotechnical work
Selecting, coordinating, and managing the wind resource, geotechnical,engineering,
and permitting consultants and ensuring that their deliverables are on time and within
budget
Working with AVEC’s Community Liaison to develop the Existing and Future Energy
Costs and Markets Memorandum and the Conceptual Business and Operating Plan
Working to develop the Economic and Financial Analysis
Contractors for this project would include:
Wind Resource Consultant.AVEC currently has an on-call contract with V3 Energy, LLC for
wind resource studies and reports.It is likely that V3 would work on this project. Doug
Vaught’s (V3’s owner) resume is attached. V3 would:
o Supervise the installation of the met tower
o Consult on the operation and maintenance of the tower
o Draft the wind resource report
o Geotechnical consultant.AVEC would select and employ an experienced geotechnical
consultant who would:
o Conduct a geotechnical and natural hazards field study and report of the project
area
Engineering consultant.AVEC would select and employ an engineering consultant who
would:
o Provide conceptual design and engineering specifications for the wind turbines
Environmental Consultant.AVEC currently has an on-call contract with Solstice Alaska
Consulting, Inc for environmental permitting. It is likely that Solstice would work on this
project. Robin Reich’s (Solstice’s president) resume is attached. Solstice would:
o Consult with agencies
o Develop and submit permit applications
o Document mitigation requirements
Selection Process for Contractors:The geotechnical and engineering consultant selection
would be based upon technical competencies, past performance, written proposal quality, cost,
and general consensus from the technical steering committee.The selection of the consultant
would occur in strict conformity with corporate procurement policies, conformance with OMB
circulars, and DCAA principles.
3.5 Project Communications
Discuss how you plan to monitor the project and keep the Authority informed of the status.
AVEC would require that monthly written progress reports be provided with each invoice
submitted from contractors. The progress reports would include a summary of tasks
completed, issues or problems experienced, upcoming tasks, and contractor’s needs from
AVEC. Project progress reports would be collected and forwarded as one package to the AEA
project manager each month.
Renewable Energy Fund
Grant Application Round IV
AEA11-005 Grant Application Page 8 of 18 7/21/2010
Quarterly face-to-face meetings would occur between AVEC and AEA to discuss the status of all
wind projects funded through the AEA Renewable Energy Grants program. Individual project
meetings would be held, as required or requested by AEA.
3.6 Project Risk
Discuss potential problems and how you would address them.
Site Control/Access.Sometimes site control for the placement of met towers or turbines is
difficult; however,because the community supports the project (letters of support have been
received from all community entities), it is not expected that gaining site control would be
difficult.
Weather.Weather could delay geotechnical fieldwork and/or the erection of the met tower;
however, an experienced consultant, familiar with Alaskan weather conditions, would be
selected. It unlikely that a delay in the total project schedule would occur if the fieldwork or
erection of the met tower is delayed. It is possible to erect the met tower during winter
months. The met tower would be installed to handle the Eek’s coastal Alaska winter weather
conditions. The met tower would be monitored by local AVEC personnel to ensure the met
tower is up and functioning properly throughout the year.
Construction Funding.By having the project designed and permitted, AVEC would be prepared
to capitalize on many funding opportunities.
Environmental Permitting.Permits would be acquired as a part of this project. AVEC would
hire an environmental consultant familiar with permitting wind projects in Alaska. Early
consultation with agencies would occur in order to flesh out location, natural and social
environment, specific species, and mitigation issues. The consultant would work openly with
the agencies and conduct studies as appropriate.
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 request ing 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.
The wind resource in Eek is estimated based on wind studies completed in the nearby
communities of Quinhagak, Bethel, and Kongiganak. The wind resource in Quinhagak was
measured by V3 Energy with a met tower study from October,2005 to May,2007 (See Wind
Renewable Energy Fund
Grant Application Round IV
AEA11-005 Grant Application Page 9 of 18 7/21/2010
Resource Report in Tab G.). The annual average wind speed at 30 meters was calculated to be
6.3 m/s, wind power density at 30 m of 338 W/m
2 (wind power class 4), Weibull k of 1.87, mean
TI of .088 and power law exponent of 0.197. Quinhagak classified as an IEC Class IIIC site
(extreme wind and turbulence behavior).
Other data sources, including a March 2006 AEA Report (M. Devine) for Chefornak, indicate
measured annual wind speed average in Bethel at 6.9 m/s and Kongiganak at 7.3 m/s. The
Bethel and Kongiganak data indicated similar Weibull k, turbulence and wind shear values as
Quinhagak. Given that Eek was not directly measured for wind resource, but the referenced
communities of Quinhagak, Bethel and Kongiganak bracket Eek in three directions and share
similar topographic features, the referenced data sources are thought highly representative of
the expected wind in Eek. Of the three referenced communities, the wind data in Quinhagak
was selected to represent Eek as it exhibited the lowest average wind speed and; therefore,is
the most conservative for this analysis. The actual wind resource in Eek may be higher; closer to
that measured in Kongiganak. If true, energy production from a proposed wind turbine would
be higher than estimated in this proposal.
Solar power from photovoltaic solar arrays is a potential alternative energy source, but has
higher capital cost and lower resource availability than wind in Eek.
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 generations system in Eek consists of three diesel generators: one 168 kW
Cummins LTA10 (10 years old), one 236 kW Detroit Series 60 (4 years old), and one 175 kW Cat
D342 (21 years old). Individual generator efficiency is not tracked, but the aggregate diesel
generator efficiency in 2009 was 12.03 kWh/gallon.
The data indicates that peak demands in Eek have remained relatively constant over the past
five years with a maximum one-minute average peak of 188 kW occurring in 2006. Average
demand over the same period was approximately 88 kW.
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.
Existing energy infrastructure in Eek is primary diesel fuel for electrical power generation,
heating oil for boiler (thermal) and home heating, thermal heat recovery from the diesel engines
at the power plant, and diesel and gasoline fuel for transportation needs.In 2009,64,192
gallons of diesel fuel was consumed to generate 772,293 kWh.
The anticipated effects are less usage of diesel fuel for electrical power generation and less
usage of heating fuel for boiler operations (due to injection of excess wind power to the thermal
heat recovery loop).The diesel generator use in Eek would be decreased, thereby decreasing
generator operations and maintenance costs and enabling generators to last longer and need
fewer overhauls.

AEA11-005 Grant Application Page 10 of 18 7/21/2010
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
Eek is located 35 air miles south of Bethel in the Yukon-Kuskokwim Delta, and 420 miles west of
Anchorage. Average temperatures range from 6 to 57
o F. Twenty nine percent of the
population is below the poverty line; the median household income is $27,500 —about half of
the State’s median household income of $59,036.
At present, Eek is a stand-alone electric power system with no intertie or connection beyond the
village itself.The electricity consumption (sold) in Eek in 2009 was 731,430 kWh. The load of is
highest during the winter months, with the bulk of electricity consumed by residences and the
school.If this study finds that winds are suitable, the addition of a wind turbine to the electric
generation system could reduce the amount of diesel fuel used for power generation and for
heating.
Eek is classified as an isolated village, relying on air transportation for delivery of medical goods
and transport of sick or injured individuals. Reliable electric service is essential to maintaining
vital navigation aids for the safe operation of aircraft. Runway lights, automated weather
observation stations, VASI lights, DME’s and VOR’s are all powered by electricity.Eek also hosts
a microwave tower and serves as a regional mini-hub connecting three surrounding villages and
Bethel.
Emergency medical service in both villages is provided in a health clinic by a health aide.
Medical problems and emergencies must be relayed by telephone or by some other
communication means for outside assistance. Operation of the telephone system requires
electricity. Reliable telephone service requires reliable electric service.
Like all of Alaska, Eek subject to long periods of darkness. Reliable electric service is essential for
the operation of home lighting, streetlights, and security lighting.Outside lighting greatly
improves the safety of village residents.
Eek is a traditional Yup'ik Eskimo village with a subsistence lifestyle. About 90% of residents’
diet consists of salmon caught near the community and stored in refrigerators and freezers.
Refrigeration is essential for the extended storage of perishable food stuffs, and reliable electric
service is essential for proper freeze storage of food.The construction of the proposed project
would augment and improve the existing power generation system by incorporating a locally
available renewable resource.

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
Renewable Energy Fund
Grant Application Round IV
AEA11-005 Grant Application Page 11 of 18 7/21/2010
Anticipated annual generation
Anticipated barriers
Basic integration concept
Delivery methods
Renewable Energy Technology:Wind power is renewable energy option of choice for Eek. Of
the wind turbine options available on the market, the “village” scale turbine size (50 to 250 kW)
is considered most appropriate for Eek’s load profile. AVEC plans to conduct a feasibility
analysis and resources assessment to determine what turbine would be best suited for Eek’s
small load and single phase electric system.
Optimum installed capacity/Anticipated capacity factor/Anticipated annual generation.The
purpose of this work is to gather background information to plan a future alternative energy
facility. Anticipated capacity and generation would be examined for a number of turbine types
to determine the best option for the community.
Anticipated barriers.The potential barriers to success of this project include weather,
permitting,site control,and construction funding.Weather is a minor barrier and does not pose
a threat to the completion of this project.Permitting, based on an initial investigation does not
appear to be a significant hurdle to completing this phase of the project. Construction funding
would be easier to obtain with design and permits in hand. Site control should not be difficult to
obtain, since the City, Tribe, and Iqfijouaq Corporation support the project (See Section 8 and
Tab D).
Basic integration concept/Delivery methods.The wind turbines would need to interconnect
with the existing diesel power plant. Secondary load control would dispatch boilers as required
to use excess wind energy while allowing the diesel generators to continue running at efficient
levels.Conceptual design, to be completed as a part of this project, would detail how power
from a wind turbine would be integrated and delivered into the existing system in Eek. The
delivery method would be examined, since Eek has a single phase system and since some
turbines are not suited for this type of system.
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.
As seen in the Google Earth image below, the proposed turbine site is on the old airstrip on the
east side of the village, near an existing lattice-structure communication tower. Site control has
not been obtained but no problems are expected as the community has expressed a strong
interest in wind power and the old airstrip is the best location possible with respect to access,
proximity to the airport, and foundation issues.Letters of support have been received from all
community entities.

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
FAA Air Navigation Hazard Permitting.A non-hazard determination would be sought from the
Federal Aviation Administration as soon as the met tower location has been determined. It is
expected that this determination would be issued within one month, since the location would
be selected based on airspace availability and limitations.
After the turbine location and type have been selected, AVEC would seek a non-hazard
determination from FAA for the potential turbines. AVEC would to this early in the process, to
ensure that enough time and resources are allocated to this effort. It is expected to take about
3 month to obtain the determination for the turbines.The turbines would be going up near an
already permitted 300 feet tall microwave tower; therefore, it is unlikely that FAA would object
to installing turbines in this area.
Endangered Species Act/Migratory Bird Treaty Act Consultation:Consultation with the U.S.
Fish and Wildlife Service (USFWS)in compliance with the Endangered Species Act and Migratory
Bird Treaty Act would be required to install the met tower. A finding letter stating that the
project would not be expected to impact threatened or endangered species or birds would be
drafted and submitted to the USFWS once AVEC is assured this project is funded. It is expected
that AVEC would receive concurrence from the Service within one month. The authorization
would be issued prior to initiating met tower work in October 2011.
After the turbine location and type has been selected, AVEC would prepare another letter to the
USFWS stating that the project would not be expected to impact birds under their jurisdiction. It
Renewable Energy Fund
Grant Application Round IV
AEA11-005 Grant Application Page 13 of 18 7/21/2010
is expected that the USFWS would concur with AVEC’s finding within one month of receiving the
letter.
Clean Water Act (Section 401) Permit:If all project components are constructed on the existing
runway, no U.S. Army Corps of Engineers (Corps)Wetlands Permit would be needed. However,
if any component is proposed adjacent to the runway, a Corps permit would be needed.
Because of the limited footprint of the met tower and geotech work,a “Nationwide Permit”
would be sought. The application/preconstruction notice would be submitted to the Corps once
funding is assured, and the permit would issued prior to initiating met tower work in October
2011.
If the wind turbines or their access are constructed off of the old runway, an individual wetland
permit would be sought from the Corps. The application would be submitted once conceptual
design has been completed. It is expected that the permit would be issued within 3 months.
Coastal Plan Consistency Determination-A State of Alaska Department of Natural Resources,
Division of Coastal and Ocean Management (DNR-DCOM) Coastal Project Questionnaire and
Enforceable Policies Consistency Determination (CPQ) would be prepared and submitted after
the conceptual design of the turbines is completed. By statute, it would take at least 60 days to
complete the permitting process.(Because a Corps’ Nationwide Permit exists,a DNR-DCOM
determination is not needed for the met tower.)
4.3.4 Environmental
Address whether the following environmental and land use issues apply, and if so how they will
be addressed:
Threatened or Endangered species
Habitat issues
Wetlands and other protected areas
Archaeological and historical resources
Land development constraints
Telecommunications interference
Aviation considerations
Visual, aesthetics impacts
Identify and discuss other potential barriers
Threatened or endangered species.The U.S. Fish and Wildlife Service would be consulted to
ensure that installation of a met tower and the construction of the wind turbines would have no
affect on threatened or endangered species, particularly Steller’s eiders. Construction would be
timed to avoid impacts to migratory birds in compliance with the Migratory Bird Treaty Act.
Habitat issues.During permitting,the project team would work with agencies to ensure that
the project would not impact any State refuges, sanctuaries, or critical habitat areas, federal
refuges or wilderness areas, or national parks.
Wetlands and other protected areas.If the met tower or turbine is placed off the runway, it
would likely be placed in a wetland location. An U.S. Army Corps of Engineers’ wetlands permit
would be needed.
Archaeological and historical resources.Compliance with the National Historic Preservation Act
and consultation with the State Historic Preservation Officer would be conducted prior to
construction of the wind turbines.

Land development constraints.AVEC is currently working with the Iqfijouaq Corporation to
gain site control.
Aviation considerations.The turbines would be located away from the active airport and
outside any important operational aircraft area. The turbines would be going up near an already
permitted 300 feet tall microwave tower; therefore, it is unlikely that FAA would object to
installing turbines in this area.
Visual, aesthetics impacts.It is likely that residents would be willing to accept some aesthetic
impacts in the interest of lowering the cost of energy. AVEC would conduct community
meetings to discuss community impacts and how they could be minimized.

funds.AVEC plans to conduct a Feasibility Analysis, Resources Assessment, and Conceptual
Design to assess the possibility of using wind power in Eek. This work would cost $150,000.
AVEC requests $142,500 from AEA. AVEC would provide $7,500 as an in-kind contribution.
Identification of other funding sources.Once the turbine type is determined, the next phase of
this project would be final design and construction. Although it is difficult to determine without
an assessment of the resource and what type, size, and number of turbine would be needed,
AVEC expects that final design and construction would cost $750,000. It is possible that the
funding for this work could come from a USDA Rural Utility Service program, the Denali
Commission, or another grant program.
Projected capital cost of proposed renewable energy system/projected development cost of
proposed renewable energy system.The final phase of this project would be Design and
Construction and Commissioning (Phase IV). AVEC estimates that this phase could cost
$750,000. AVEC would provide a 10% cash match ($75,000)for the construction project.
4.4.2 Project Operating and Maintenance Costs

4.4.4 Project Cost Worksheet
Complete the cost worksheet form which provides summary information that will be considered
in evaluating the project.
Please see cost/benefit sheet under Tab C.
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
Potential annual fuel displacement:The project could decrease diesel use by 13,632 gal/yr
(based on preliminary numbers and 80% turbine availability) and 272,630 gallons over the
lifetime of the project. Based on ISER’s estimated fuel costs, this project could save
approximately $48,800 year during its first full year of operation (planned to be 2014).
Anticipated annual revenue/Potential additional annual incentives/Potential additional
annual revenue streams.Because this project is in the concept design stage, revenue and
Renewable Energy Fund
Grant Application Round IV
AEA11-005 Grant Application Page 16 of 18 7/21/2010
incentives are unknown.
Non-economic public benefits.The anticipated benefits of installation of the wind turbines
would be reducing the negative impact of the cost of energy by providing a renewable energy
alternative.This project could help stabilize energy costs and provide long-term socio-economic
benefits to village households.Locally produced, affordable energy will empower community
residents and could help avert rural to urban migration, which would help larger Alaska
communities.
Eek will be a pilot project for communities with smaller populations and lower electric demand.
While larger villages have mostly been evaluated for wind resources, studying Eek will enable
AVEC to discover ways to economically integrate wind power into the diesel-generating plants in
smaller villages.The lessons learned from this project could be used in other small villages
throughout the State.
This project would help AVEC to determine potential locations to be served by recovered heat.
If determined feasible, the terms of recovered heat agreements would be negotiated with
entities to be served. Once the wind project is constructed and heat recovery systems are in
place, the costs to operate important facilities in Eek including the water treatment plant and
school,could be decreased, enabling managing entities (City of Eek, Eek Traditional Council and
Iqfijouaq Corporation,Yukon-Kuskokwim School District) to operate more economically.
Stabilized energy costs would also allow community entities to plan and budget for
important community infrastructure listed in the Eek Community Comprehensive Plan
(Native Village of Eek, 2004), including the expansion of the health clinic, a piped water and
sewer system, and additional housing.
Eek residents health and safety would benefit from the environmental benefits resulting from a
reduction of hydrocarbon use, including:
Reduced potential for fuel spills or contamination during transport, storage, or use (thus
protecting vital water and subsistence food sources)
Improved air quality
Decreased contribution to global climate change from fossil fuel use
The community of Eek has a small electricity load and AVEC is interested in investigating
turbines other than the Northwind 100s to install in the community. The investigation of
other turbines not currently used at other AVEC facilities or in rural Alaska would help
other communities to understand whether a different turbine is suitable for their
community.
The community of Eek has a single phase electric system. Investigation of other turbines
would also assist other single phase community to know whether there is a cost effective
solution other than changing to a three phase system.
This project would help with the understanding of the wind resource in Northwest Alaska. Data
acquired from this study assist nearby communities at the mouth of the Kuskokwim River to
understand their wind resource.

Eek Wind Power Report
V3 Energy LLC 2 of 17
Summary Information
The wind resource in Eek is estimated based on wind studies completed in the nearby communities of
Quinhagak, Bethel, and Kongiganak. The wind resource in Quinhagak was measured from October 2005
to May 2007 with a 30 meter met tower located near the site of the recently-constructed wind turbines.
The mean wind speed in Quinhagak (at 30 meters) was measured at 6.3 m/s with calculated wind power
density of 338 W/m2. Quinhagak classified as IEC Class III-c.
Other data sources, including a March 2006 AEA Report (M. Devine) for Chefornak, indicate mean
annual mean wind speed in Bethel as 6.9 m/s and Kongiganak as 7.3 m/s. The Bethel and Kongiganak
data indicated similar Weibull k, turbulence and wind shear values as Quinhagak. Given that a met
tower study has not been conducted in Eek, but the referenced communities of Quinhagak, Bethel and
Kongiganak bracket Eek in three directions and share similar topographic features, the referenced data
sources are thought highly representative of Eek’s expected wind resource. Of the three referenced
communities, the wind data in Quinhagak was selected to represent Eek as it exhibited the lowest
average wind speed and hence is most conservative. The actual wind resource in Eek may be stronger;
closer to that of Kongiganak. If true, energy production from the proposed wind turbine would be
higher than estimated in this report.
Wind Turbine Performance
It is perhaps counterintuitive that wind power density and wind class do not correlate linearly with
turbine power output. This is due to a number of factors, including theoretical limitations of a lift-
producing aerodynamic device (the turbine rotor) and practical limitations of generator weight and
rated output. For these reasons and others, a wind turbine in a low power class wind regime may still
produce sufficient energy to warrant installation of turbines. A simplistic consideration of possible
turbine output in Eek is to model power output of a particular turbine with mean of monthly means data
collected to date and extrapolating to the turbine hub height.
Turbine performance was analyzed with the HOMER software using the Northern Power Northwind 100
B model (100 kW rated output, 21 meter rotor diameter), the (remanufactured) Vestas V17 (90 kW
rated output, 17 meter rotor diameter) and the Bergey Excel-S (10 kW, 7 meter rotor diameter). Note
that the NW100/21 is available with a 37 meter tower (a 30 meter tower may be available by special
order), the Vestas with a 26 meter tower, and the Bergey is available with a wind range of tower
options, including tubular, lattice and tilt-up options. For this study, 30, 37 and 43 meter standard
guyed lattice towers were considered.

Wind Farm
AVEC has proposed installation of one or more wind turbines to create a wind-diesel hybrid power
system for the village of Eek. HOMER software was used to create an Eek village simulation model.
Village Load
An Eek hourly load profile was synthesized using the Alaska village load calculator Excel spreadsheet
developed by Alaska Energy Authority several years ago. The results were adjusted slightly to match
actual village average and peak loads of Eek documented by AVEC in their 2008 annual power
generation report. The result is a virtual Eek village with a 90 kW average load, 144 kW peak load and
average daily power usage of 2,156 kWh/day. Seasonal, daily and DMap profiles of the Eek virtual load
are shown below.

Eek Wind Farm Performance
HOMER software was used to estimate wind turbine production, wind penetration and fuel
displacement for wind power input from operation of one Northern Power NW100/21 and three to six
Bergey Excel-S turbines in an Eek wind regime based on nearby Quinhagak met tower data. HOMER
modeling may in some cases yield lower production estimates than Alaska Energy Authority (AEA)
methods which consider only performance of the turbine displacing fuel usage from diesel generators
supplying essentially an infinite load. HOMER considers the dynamics of the actual village load and the
reality that turbines will on occasion generate more power than can be absorbed by the village electric
load. During these times, excess energy must be diverted to a secondary use, such as a thermal heating
load, or turbine operation must be curtailed. For HOMER modeling, it was assumed that a diesel
generator would remain on-line at all times with a minimum load of 25 kW. Control constraints for the
model are system operating reserves of 10% of current load plus 50% of wind power input.

Data Quality Control Summary
Data was filtered to remove presumed icing events that yield false zero wind speed data. Data that met
the following criteria were filtered: wind speed < 1 m/s, wind speed standard deviation = 0, and
temperature < 3 °C. Other obvious icing data was removed even if it did not meet the above criteria. An
offset failure in the temperature sensor occurred on July 7, 2006 resulting logged temperature data
reading approximately 30° C lower than normal. An offset correction of +32.8° was added to all
subsequent temperature data. It is not known if this offset correction is completely accurate for the ten
months it covers, but a near accurate temperature record of the site was deemed more desirable than
deleting most of the temperature record.

Measured Wind Speeds
The Channel 1 (30-meter [A]) anemometer wind speed average for the reporting period is 6.31 m/s. The
Channel 2 (30-meter [B]) anemometer wind speed average is 6.30 m/s and the Channel 3 (20-meter)
anemometer wind speed average for the reporting period is 5.80 m/s.
Typically, the highest wind speeds occur during the winter months of October through March with the
lowest winds during the summer months of May through September. The unusually low winds
measured in January 2006 were due to a persistent high pressure system over Alaska that month that
yielded calm winds and extremely cold weather Statewide. January 2006 was then followed by an
extremely windy February 2006. As one can see, the winds during winter 2005/06 were quite different
from winter 2006/07.
The daily wind speed profile indicates that the lowest winds of the day occur in the morning at about 3
a.m. to 9 a.m. and the highest winds of the day occur in the afternoon and early evening hours of about
1 p.m. to 8 p.m. This correlates reasonably well with the times of day where load demand is highest.

Wind Shear
The power law exponent was calculated at 0.197, indicating moderate wind shear at the Quinhagak met
tower test site. The shear data is shown in greater detail in the accompanying seasonal, daily and
directional plots of the power law exponent, or wind shear.
The practical application of this data is that one can expect appreciably higher power production with
increased turbine tower height. A tower height/power production cost tradeoff study is recommended.
Note that some of the observed shear may be due to the presence of tanks and other structures north
of the met tower test site and would not be indicative of general wind shear conditions in the Quinhagak
area.

Probability Distribution Function
The graphed probability distribution function provides a visual indication of measured wind speeds in
one meter per second “bins.” Note that most wind turbines do not begin to generate power until the
wind speed at hub height reached 4 m/s; using this criteria, 27% of Quinhagak’s winds are calm (less
than 4 m/s). The black line in the graph is a best fit Weibull approximation of the wind speed
distribution. At the 30 meter level, the Weibull parameters are k = 1.87 (indicates a relatively narrow
distribution of wind speeds) and c = 7.18 m/s (scale factor for the Weibull distribution).

Wind Roses
Quinhagak winds are directional in frequency (percent of time) from the north and to a lesser extent
from the southwest, south and southeast (wind frequency rose). Interestingly though, the power of the
winds (mean value by direction) indicate that the southeast winds, when they occur, are much stronger
than the northerly winds. Combining the frequency rose and the mean value rose yields the third wind
rose – the total value (power density) rose. This wind rose indicates frequency of power density by
direction and is most important of the three for siting of turbines.
To minimize wake turbulence, wind turbines should be located with due consideration of clear zones
from nearby obstructions and especially other turbines. If one were to consider just the frequency rose,
turbines might be placed on more of an east-west alignment. But with consideration of the total value
(power density) rose, turbines should be located on a northeast to southwest alignment with plenty of
clearance from obstructions located to the northwest and southeast of the turbines.

Turbulence Intensity
The turbulence intensity (TI) is acceptable for the north-northeast and southeast wind directions, with
mean turbulence intensity of 0.0915, indicating relatively smooth air for wind turbine operations. This
turbulence intensity is calculated with a threshold wind speed of 4 m/s (only wind speeds exceeding 4
m/s are considered). The relatively high turbulence intensity to the northeast and southwest are of little
consequence as essentially no power producing winds are from these directions.

Air Temperature and Density
Over the reporting period, Quinhagak had an annual average temperature of -3.9 degrees C. The
minimum recorded temperature during the test period was -49.1° C (see below; possibly incorrect) and
the maximum temperature 23.8° C.
Note that on July 7, 2006 the temperature sensor experienced an unusual fault in that although it
continued to record what appeared to be normal variations of temperature, the offset suddenly
changed by approximately 30° C. This offset change (-32.8° C exactly) was added to subsequent
temperature data in order to produce a best likely temperature record of Quinhagak, but because the
nature of the fault is unknown, the corrective measure may be faulty to some extent. Hence, it is
unlikely that the extreme low temperature data readings of -40° C and lower during the winter months
of 2006/07 are completely accurate, although 2006/07 was a very cold winter in general. Despite the
likelihood of error with the post 7/7/06 temperature data, it is more accurate for power density and
turbine performance estimates to insert a corrective offset than to delete the faulty temperature data
altogether.
Consequent to the rather cool average temperature in Quinhagak, air density is rather high, boosting
the nominal performance of wind turbines. The average air density in Quinhagak is 1.326 kg/m3,
approximately eight percent higher than standard sea level atmospheric air density of 1.225 kg/m
3. This
density variance from standard is accounted for in turbine performance predictions in this report. Note
that the density estimates, because they are based on calculations using temperature data and not
direct measurement, are likely a few percent lower than actual.
