(excellent) wind resource with an average wind speed of 7.62 m/s. Work under this grant will include
updating the wind resource report, conducting a geotechnical investigation at a proposed wind site,
completing the CDR with the preliminary design of a wind farm.
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, local jobs created, etc.)
Project benefits are summarized here and further explained in Section 5.1.1.
Mountain Village (population: 830) is a traditional Yup’ik Eskimo village with most residents supported
by subsistence activities. Local economies are a mix of commercial fisheries and local wage positions at
the schools, cities, and Native corporations. According to the Alaska Department of Labor and
Workforce Development, 31.01% of the population was unemployed in 2012. According to the 2007-
2011 American Community Survey (ACS), 20.58% of the population is living below the poverty level. The
median household income was $47,000, as compared with the median household income for Alaska at
$69,014. High energy costs are an extreme hardship for the residents of Mountain Village.
The primary benefit of this project is to reduce and stabilize the long term energy costs in Mountain
Village by providing a renewable energy resource that will displace significant amounts of fuel annually.
When this project is constructed, electricity costs to non-PCE customers will be decreased, which is
expected to have many positive community benefits. The households and other PCE-eligible customers
may see a small reduction in their rates but certainly the steep rise of energy costs will be eased. Non-
PCE customers will see a more significant decrease in electric rates.
A detailed description of the economic, social, and environmental benefits is found in Section 5.1.1.
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 project cost of this wind energy feasibility and conceptual design in Mountain Village is $130,000 of
which $123,500 is requested in grant funds from AEA’s renewable energy fund. The remaining $6,500

provide assistance on an as-needed basis.
Resumes are included under Tab A.
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.
AVEC has systems in place to accomplish reporting requirements successfully. In 2012, AVEC
successfully met reporting requirements for 56 state and federal grants. An independent financial audit
and an independent auditor’s management letter completed for AVEC for FY2012 did not identify any
deficiencies in internal control over financial reporting that were considered to be material weaknesses.
In addition, the letter stated that AVEC complied with specific loan and security instrument provisions.
The project will be managed out of AVEC’s Project Development Department. For financial reporting,
the Project Development Department’s accountant, supported by the Administrative Services
Department, will prepare financial reports. The accountant will be responsible for ensuring that vendor
invoices and internal labor charges are documented in accordance with AEA guidelines and are included
with financial reports. AVEC has up-to-date systems in place for accounting, payables, financial
reporting, and capitalization of assets in accordance with AEA guidelines.
AVEC will require that monthly written progress reports be provided with each invoice submitted from
contractors. The progress reports will include a summary of tasks completed, issues or problems
experienced, upcoming tasks, and contractor’s needs from AVEC. Project progress reports will be
collected, combined and supplemented as necessary and forwarded as one report to the AEA project
manager each month. Quarterly face-to-face meetings will occur between AVEC and AEA to discuss the
status of all projects funded through the AEA Renewable Energy Grants program. Individual project
meetings will be held, as required or requested by AEA. Meera Kohler, AVEC’s President and CEO, may
be contacted as an alternative manager.
3.5 Project Risk
Discuss potential problems and how you would address them.
The risks associated with this project are low because wind resource data has been collected and
because AVEC obtained site control years ago for a wind project. Much of the work has been completed
and the project has valuable community support.
Weather. Weather could delay consultants getting in and out of the community to conduct site visits
and/or the geotechnical survey. However, AVEC will select consultants familiar with Alaskan weather
conditions and getting work done in rural Alaska.

AVEC is a cooperative and follows the International Co-operative Alliance’s Seven Principles of
Cooperatives. One of the most important of those principles is titled Democratic Member Control and
refers to the men and women who serve as representatives being accountable to the membership.
AVEC’s member communities, especially the community involved in a grant program such as the REF,
have expectations for projects regarding outcomes, schedule, budget, and quality of work. AVEC
member communities and Board of Directors receive regular project status updates. When problems
are reported, either formally through status reports or informally through other communications,
member communities expect solutions.
SECTION 4 – PROJECT DESCRIPTION AND TASKS
The level of information will vary according to phase(s) of the project you propose to
undertake with grant funds.
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. For pre-construction applications, describe
the resource to the extent known. For design and permitting or construction projects, please
provide feasibility documents, design documents, and permitting documents (if applicable) as
attachments to this application.
Based on a wind resource report completed by V3 Energy (Tab G), the wind resource measured near
Mountain Village is very good. The wind power was measured as a Class 5. In addition to high average
wind speeds and high wind power density, the met tower site experienced very low turbulence and low
extreme wind speed probability. An average wind speed of 7.62 m/s was measured over the 21 months of
data collection. Due to cool summers and cold winters, Mountain Village experiences higher than
standard air density, exceeding the standard density of 1.220 kg/m3 by 6.3 percent at a 50-meter
elevation.
Other energy resources are not feasible for the following reasons:
The installed cost of photovoltaic solar arrays will be higher per kW produced than the installed
costs of wind.
Generating power from the hydrokinetic power is not yet an established technology or
commercially available technology.
Hydropower resources are not available in the area.
Biomass resources are limited by the lack of resources near the communities.
Wind energy as a supplement to diesel generators for electricity generation is considered the most viable
and developable source of renewable energy for Mountain Village.
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.
Renewable Energy Fund Round VII

AEA 2014-006 Grant Application Page 10 of 24 7/1/2013
Four diesel generators power Mountain Village. The power plant efficiency in 2012 was 13.25 kW/gal
(AVEC estimate) or 13.51 (PCE estimate). Generator models, size and age are listed below:
Engine Make Model Kw Rating Age (Yrs)
Caterpillar 3412 1200 350 28.9
Caterpillar 3456 505 8.3
Caterpillar 3412 1800 601 30.4
MTU 12V2000 710 9.6
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.
Mountain Village uses diesel fuel for electrical power generation, heating oil for boiler (thermal) and home
heating, and diesel and gasoline fuel for transportation needs. Diesel fuel consumption for power
generation in Mountain Village in 2012 was 209,103 gallons.
The primary effect of a wind farm in Mountain Village will be decreased usage of diesel fuel for electrical
power generation. Also, diesel generator loads will be decreased, potentially decreasing generator
operations and maintenance costs. Another anticipated effect of this project will be decreased use of
heating fuel for boiler operations due to injection of excess wind power as thermal heat to a community
system. This feasibility level project will help to determine the anticipated effects.
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
The electricity generated in Mountain Village was 2,824,188 kWh in FY 2012. The load is highest during
the winter months, when the community experiences heavy winds and extended periods of darkness. The
average load was 330kWh/month with the peak load occurring in January at 600 kWh. With no renewable
energy systems in place, the community relies on diesel fuel to meet its energy needs. The 20-year
average cost of diesel in the community is estimated to be approximately $5.14/gal (ISER 2012, medium
projection plus social cost of carbon.) In FY 2012, the cost of delivered diesel fuel to Mountain Village for
the AVEC power generation was $3.99/gal.
The addition of one or more wind turbines to the electric generation system could reduce the amount of
diesel fuel used for power generation, thereby decreasing the costs to produce power. Additional project
impacts on energy consumers are discussed in Section 5.

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. Wind power is the renewable energy option of choice for Mountain
Village. Based on the wind resource report compiled by V3 Energy, LLC., with 21 months of data collection,
Mountain Village is has a Class 5 (excellent) wind resource. In addition to high average wind speeds, the
mean power density is 523 W/m2 and the site experiences very low turbulence and low extreme wind
probability.
Optimum installed capacity/Anticipated capacity factor/Anticipated annual generation. The purpose of
this work is to gather background information and plan a future alternative energy facility. Anticipated
capacity and generation will be examined for a number of turbine types to determine the best option for
the community.
Anticipated barriers. Weather, permitting, site control, and construction funding are common barriers to
wind project success, but none are anticipated to be barriers to this project. 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
will be easier to obtain with design and permits in hand. Site control has been obtained (See Section 8 and
Tab G).
Basic integration concept/Delivery methods. The wind turbines will interconnect with the existing diesel
power plant. Secondary load control will be studied to determine whether dispatch boilers could be
installed 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, will further detail how power from a
wind turbine will be integrated and delivered into the existing electric system in Mountain Village. The
delivery method will also be examined.
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.
Azachorok, Inc., the Native Corporation for Mountain Village has issued a 50 year lease to AVEC to
construct wind turbines and any associated infrastructure. The community is in full support of the wind
project, and no additional work will be needed to gain site control.

AEA 2014-006 Grant Application Page 12 of 24 7/1/2013
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 will be needed to complete the work proposed under this grant. The previously installed met
tower operated under a “Determination of No Hazard to Air Navigation” from Federal Aviation
Administration (FAA) and under a “no effect on endangered or threatened species” finding from the U.S.
Fish and Wildlife Service (USFWS). Geotechnical field work is allowable in wetlands under a Nationwide
Permit from the Army Corps of Engineers (Corps).
After design of the wind farm is further developed AVEC will seek permits and authorizations for
construction from the Corps, USFWS, FAA, and the State Historic Preservation Officer (SHPO), depending
on site conditions and agency input. AVEC will develop a list of needed environmental permits and
authorizations in the CDR developed during 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
Because this is a feasibility and conceptual design effort, environmental permits and authorizations will
not be sought during this phase; however, based on an understanding of environmental conditions in
Mountain Village and approvals typically needed for wind projects, it is likely that the following topics will
be addressed in the CDR:
Threatened or Endangered species. The USFWS will need to be consulted to ensure that the construction
of the wind farm will have no harmful impact on threatened or endangered species. Construction will
need to be timed to avoid impacts to migratory birds in compliance with the Migratory Bird Treaty Act.
Habitat issues. During permitting, the project team will work with agencies to ensure that the project will
not impact any state refuges, sanctuaries or critical habitat areas, federal refuges or wilderness areas, or
national parks.
Wetlands and other protected areas. It is likely that the wind turbine could be placed in designated
wetland locations. A Corps wetlands permit will be sought after more detailed design is available.

Archaeological and historical resources. In accordance with the National Historic Preservation Act, the
undertaking will need to be reviewed by the SHPO. During formal Section 106 consultation, the SHPO will
determine whether additional surveys and mitigation will be required.
Land development constraints. AVEC has been granted a 50-year lease to the project site by Azachorok,
Inc., the Native Corporation of Mountain Village. The lease allows for the construction of turbines as well
as any infrastructure needed to support the project.
Aviation considerations. A finding of “Determination of No Hazard to Air Navigation” will be sought from
the FAA once the turbines and site have been selected and in a future phase. The proposed project site
was already issued a “Determination of No Hazard to Air Navigation” for installation of the met tower.
Based on the finding issued for the met tower at the project site, AVEC does not foresee issues with
obtaining this determination for a future wind farm.
Visual, aesthetics impacts. The turbines will be constructed outside the community and along an existing
road; therefore, it is likely that there will be little concern for visual or aesthetic impacts. Communities
often note that turbines offer a helpful visual guide point when traveling outside the village. AVEC will
conduct community meetings to discuss visual impacts and how they could be minimized, in the unlikely
event that visual issues arise.
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,

will be final design and construction. Without an assessment it is difficult to determine the type, size, and
number of turbines that will be needed. Currently, AVEC expects that final design and construction of a
450 kW capacity system will cost $4,833,000. (This is assuming two 225 kW Aeronautica AW29-225 wind
turbines; gross AEP each at 50 m hub height; two turbines with 80% availability: 1,137 MWh/year.) AVEC
will provide a 5% cash match for the permitting and design phase of the project and a 10% cash match for
the construction.
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.)
Once the turbines are installed, AVEC estimates the cost of operating and maintaining to be around
$55,756 annually. These estimates are based on AEA’s default cost of wind energy of $0.049/kWh. AVEC
will provide the funds to maintain consistent operation of the turbines.
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
AVEC, the existing electric utility serving Mountain Village, is a member-owned cooperative electric utility.

Mountain Village is a PCE eligible community. Mountain Village consumers received $417,624 in FY12 in
PCE credits for eligible kWh sales (1,111,280 kWh) to residences and community facilities. About 58% of
sales in Mountain Village were not eligible for PCE and, as a result, those consumers will receive the
entire benefit of wind energy generated reduction in power costs through their electric rates. Power
sales that are eligible for PCE will see 5% of the benefit of reduced electric costs in their electric rates,
with the other 95% accruing to the state of Alaska through reduced PCE credits to end users.
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
The primary benefit of this project is to reduce energy costs in Mountain Village by providing a
renewable energy resource.
Potential annual fuel displacement. Integration of wind turbine power into the proposed electrical
power generation system will offset diesel consumption in Mountain Village by 84,225 gal/year (based
on current generator efficiency of 13.51 kWh/gal and 80% availability).
Anticipated annual revenue/Potential additional annual incentives/Potential additional annual
revenue streams. Tax credits are not expected to be beneficial to the project due to AVEC’s status as a
non-profit entity. Nonetheless, in addition to saving the direct cost of fuel, AVEC could sell green tags
from the project.
Additional economic benefits
Mountain Village is a traditional Yup’ik Eskimo village with most residents supported by subsistence
activities. Local economies are a mix of commercial fisheries and local wage positions at the schools,
cities, and Native corporations. According to the 2007-2011 American Community Survey (ACS), the
average unemployment rate for those years was 31.1%. In Mountain Village, 20.58% of the population
was living below the poverty level. The median household income was $47,000, as compared to the
average Alaskan median household income of $69,014.
The high cost of electricity in Mountain Village, even considering Power Cost Equalization credits where
they do apply, at $0.22/kWh is an extreme hardship for these low income families; therefore, the
reduction of the cost of power and any other direct or indirect economic benefits associated with this
project will be very beneficial to this community.

It is likely that energy costs for PCE customers will be reduced. As stated in Section 4.4.5, customers
who are eligible for PCE will see 5% of the benefit of reduced electric costs in their electric rates, with
the other 95% accruing to the state of Alaska through reduced PCE credits to end users.
It is likely that energy costs for non-PCE community institutions will be reduced allowing for better
community services. Once the wind project is constructed and wind-to-heat systems are in place, costs
to operate important community facilities (e.g. school, health clinic, tribal office, etc.) will be decreased
(see Section 4.4.5), enabling managing entities (e.g., city governments, tribe, school district) to operate
more economically. With these savings, community governments will be able to better focus on
providing important community services and functions.
It is likely that energy costs for non-PCE commercial energy customers will be reduced and savings will
be passed along to residents. Commercial enterprises in the communities are excluded from the PCE
program. Once this project is constructed, these entities will see a savings in the cost of electricity.
Local businesses, especially the store, may pass this savings along to customers. The development and
growth of local businesses like these are crippled by the high cost of energy. Decreases in electricity
costs make small businesses more viable in rural Alaskan communities like Mountain Village, which in
turn makes economic development and the addition of local jobs more likely.
Reduced commercial energy costs will benefit the entire community by increasing opportunities for
local economic development. Lower costs of energy may allow local businesses to start and flourish.
The anticipated benefits of installation of the wind turbine(s) will 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.
Project construction will benefit local businesses and residents. During construction the local economy
could benefit from the project’s purchase of local services (such as worker housing) and goods (such as
food) and construction materials (such as sand or gravel). In most AVEC construction projects some
local hire takes place and this project will not be an exception.
The State of Alaska will pay less in PCE subsidies. The state could see 95% of the benefit of reduced
electric costs once this project is constructed.
Non-economic public benefits
The CDR will include information regarding the geographic diversity of wind in the Mountain Village and
St. Mary’s area. (When the wind is blowing in Mountain Village it may not be in St. Mary’s, for example.)
It will also include information regarding how a system in Mountain Village will work in tandem with the
planned wind farm in St. Mary’s. This data will provide information for other Alaskan wind projects,
perhaps including the intertie between Mountain Village and St. Mary’s.
The Yukon River is located adjacent to the planned turbine location. The wind turbines will provide a
visual landmark for river, air, and overland travelers, which will help navigation in the area. Wind
turbine orientation and rotor speed will provide visual wind information to residents.
Another public benefit will be reduced fossil fuel emissions, which results in improved air quality and
decreased contribution to global climate change.

5.1.1 Public Benefit for Projects with Private Sector Sales
Projects that include sales of power to private sector businesses (sawmills, cruise ships, mines,
etc.), please provide a brief description of the direct and indirect public benefits derived from the
project as well as the private sector benefits and complete the table below. See section 1.6 in
the Request for Applications for more information.
This project will not provide power to any large private sector businesses. By reducing the cost of power
production, small businesses in Mountain Village, including the Store (not eligible for PCE) will see a cost
savings which may be passed along to residents in the form of lower product or services prices.

SECTION 6– SUSTAINABILITY
Discuss your plan for operating the completed project so that it will be sustainable.
Include at a minimum:
Proposed business structure(s) and concepts that may be considered.
How you propose to finance the maintenance and operations for the life of the project
Identification of operational issues that could arise.
A description of operational costs including on-going support for any back-up or existing
systems that may be require to continue operation
Commitment to reporting the savings and benefits
AVEC has the capacity and experience to administer this grant and this project. As a local utility that has
been in operation since 1968, AVEC is completely able to finance, operate, and maintain this wind energy
project for its design life. It has, with financial assistance from the State of Alaska, the Rural Utilities
Service and the Denali Commission, installed 34 turbines in 11 communities with interties to three other
communities. In 2012, wind turbines generated 4.487,594 kWh (net) and displaced an estimated 341,886
gallons of diesel fund, saving more than $1,315,000 in diesel generating costs.
Business plan structures and concepts which may be considered: The wind turbine will be incorporated
into AVEC’s power plant operation. Local plant operators provide daily servicing. AVEC technicians
provide periodic preventative or corrective maintenance and are supported by AVEC headquarters staff,
purchasing, and warehousing.
How O&M would be financed for the life of the project: The costs of operations and maintenance
(estimated at $55,756/yr) will be funded through ongoing energy sales to AVEC’s member-owners in the
villages.

Operational issues which could arise: Integration of the wind power into the new diesel power plant will
be fully evaluated during the next phase of the project, but are not anticipated to be a barrier to
successful completion of the project.
Commitment to reporting the savings and benefits: AVEC currently monitors overall generator and plant
efficiencies, maintenance costs, fuel costs, and electric system reliability in all their member communities.
Monthly and annual average statistics are analyzed by AVEC staff continuously. AVEC is fully committed
to sharing all information accrued from this project with its members and to sharing information
regarding savings and benefits with AEA.
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.
AVEC is ready to move forward on this project. Once funding is known to be secured, AVEC will complete
the geotechnical work before winter. Because the wind resource report has been completed and only
needs to be updated, conceptual design will begin quickly following the geotechnical work of summer
2014.
No other grants have been secured for this work in the past. AVEC completed the wind resource with its
operating funds and some federal funds.
SECTION 8 – LOCAL SUPPORT AND OPPOSITION
Discuss local support and opposition, known or anticipated, for the project. Include letters of
support or other documentation of local support from the community that would benefit from this
project. The Documentation of support must be dated within one year of the RFA date of July 2,
2013.
The community supports this project and is very committed to moving it forward. Letters of support for
the project have been received from the City of Mountain Village, the Asa’carsarmiut Tribe, and
Azachorok, Incorporated (Tab B).
Equally important, this project can demonstrate the real commitment of the community through their
contributions of their land. Azachorok, Inc., the Native Corporation for Mountain Village has issued, as an
in-kind contribution, a 50-year lease to AVEC to construct wind turbines and any associated
infrastructure.
SECTION 9 – GRANT BUDGET

Community Description
Mountain Village has a population of 813 people (2010 census) and is located on north bank of the
Yukon River, approximately 20 miles west of St. Mary's and 470 miles northwest of Anchorage. It is at
the foot of the 500 ft elevation Azachorok Mountain, the first mountain encountered by those traveling
up the Yukon. The climate is continental with maritime influences. Temperatures range from -44 to 80
°F. Annual precipitation averages 16 inches, with snowfall of 44 inches. High winds and low visibility are
common during winter. The Lower Yukon is ice-free from mid-June to October.
Mountain Village was a summer fish camp until the opening of a general store in 1908. This prompted
residents of Liberty Landing and Johnny's Place to immigrate. A Covenant Church missionary school was
also built in that same year. A post office was established in 1923, followed by a salmon saltery in 1956
and a cannery in 1964. The city government was incorporated in 1967. Mountain Village became a
regional education center in 1976 when it was selected as headquarters for the Lower Yukon School
District.
A federally-recognized tribe is located in the community -- the Asa'carsarmiut Tribal Council. Mountain
Village is a Yup'ik Eskimo community with traditional subsistence practices. Commercial fishing and fish
processing provide income. The sale and importation of alcohol is banned in the village.
According to Census 2010, there were 211 housing units in the community and 184 were occupied. The
Mountain Village population is 91.9 percent American Indian or Alaska Native, 4.2 percent white, 0.7
percent Asian, and 3.2 percent of the residents have multi-racial backgrounds. Additionally, 0.4 percent
of the population is of Hispanic descent.
Mountain Village, Alaska Wind Resource Report Page | 3
Water is derived from a well and is treated. Mountain Village operates a piped water and sewer system
that serves 200 households and facilities. A landfill is available. Electricity is provided by AVEC. There is
one school in the community, attended by 242 students. Local hospitals or health clinics include George
Waskey Memorial Clinic in Mountain Village. Emergency service is provided by a health aide.
A summer road links Mountain Village to Pitka's Point, Andreafsky, and St. Mary's. Mountain Village is
accessible by riverboat or barge. A state-owned 3,500' long by 75' wide gravel airstrip is available, and
floatplanes land on the Yukon River. In the winter passengers, cargo, and mail are flown in by plane.
Snowmachines and skiffs are used for local transportation.
Test Site Location
The met tower is installed on an a broad, flat ridge on Mountain Village Native Corporation land east of
the Mountain Village Airport and near the road that connects Mountain Village to the villages of Saint
Mary’s and Pitka’s Point to the east. The site is large enough to accommodate several or more large
turbines. Although the site is not at present near electrical distribution lines, near-term plans call for

Data Quality Control
Data quality is generally good with data recovery of all six anemometers greater than 90 percent and
data recovery of the two wind vanes less but also greater than 90 percent. Data loss is limited to winter
months only and is attributable to icing events, which are characterized by non-variant output of the
anemometer at the minimum offset value (essentially zero) and by non-variant output of the direction
vane at the last operable direction. Rime icing conditions have been observed at the nearby Saint
Mary’s and Pitka’s Point met towers, but it is not known if icing conditions observed in the data are due
to rime ice or freezing rain. Given the site elevation and known rime icing experience in Saint Mary’s,
caution would err toward the former.

Icing Event
Data indicating an apparent icing event in February 2011 is shown below. In the days preceding the
event, characterized by loss of anemometer function, the temperature had been -15° C, warming to 0°
C. Relatively humidity had been moderate but increased to 100 percent coinciding with the
temperature warm-up to the freezing point. At this time, on February 7, all six anemometers ceased
functioning. The moderate temperature and high humidity conditions continued for two days which
were followed by a rapid decrease of temperature to -32° C on February 11. Anemometers remained
inoperative and presumably encased in ice until February 16 and 17 when the temperature again
warmed to 0° C and humidity rose to 100 percent, indicating another precipitation event. High winds
and warming temperatures were sufficient to break loose the anemometers and they resumed normal
function.

Data Gap-fill
Although the overall loss of anemometer data due to icing was less than 90 percent, this includes the
summer months which of course do not experience icing conditions. Wintertime icing loss was much
higher, with data recovery of the anemometers as low as the 50 percent range in February 2011. Ice
event data is removed from the file to avoid biasing the mean wind speed low (zero wind speed when
the wind is likely blowing), but that can create the opposite situation, where the data set bias is high (no
recorded wind speed during the ice periods, leaving just higher wind speeds in the data set). To
overcome these errors, a data gap-fill algorithm contained in Windographer software was employed to
synthesize missing data and create a statistically truer representation of the Mountain Village wind
resource than the file without data gap-fill. Note: dotted lines below are synthesized data.

Wind Speed
Anemometer data obtained from the met tower, from the perspectives of both mean wind speed and
mean wind power density, indicate an excellent wind resource. Mean wind speeds are greater at higher
elevations on the met tower, as one would expect. Note that cold temperatures contributed to a higher
wind power density than otherwise might have been expected for the mean wind speeds. Also note, as
discussed in the previous section, that anemometer summary information is the table below is post gap-
fill. None gap-filled mean wind speeds and power densities are slightly higher than below.

Time Series
Time series calculations indicate high mean wind speeds during the winter months with more moderate
mean wind speeds during summer months. This correlates well with the village load profile where
winter months have a high electric and heat demand and summer months a lesser demand.

Probability Distribution Function
The probability distribution function (PDF), or histogram, of wind speed indicates a near-normal shape
curve, defined as the Raleigh distribution (k=2.0), defined as standard for wind power sites. As one can
see in the PDF, the most frequently occurring wind speeds are between 5 and 8 m/s with very few wind
events exceeding 25 m/s, the cutout speed of most wind turbines.

Wind Shear and Roughness
A wind shear power law exponent (α) of 0.180 indicates moderate wind shear at the site. Related to
wind shear, a calculated surface roughness of 0.114 meters (indicating the height above ground level
where wind velocity would be zero) indicates moderately uneven terrain (roughness description: few
trees) surrounding the met tower. This indicates that it would be beneficial to construct turbines at
higher hub heights in order to maximum power production.

Extreme Winds
A modified Gumbel distribution analysis, based on monthly maximum winds vice annual maximum
winds, was used to predict extreme winds at the Mountain Village met tower site. Extreme wind
analysis indicates a highly desirable situation in Mountain Village: relatively high mean wind speeds
combined with low extreme wind speed probabilities.
Industry standard reference of extreme wind is the 50 year 10-minute average probable wind speed,
referred to as Vref. For Mountain Village, this calculates to 31.5 m/s (at 50 meters), below the threshold
of International Electrotechnical Commission (IEC) 61400-1, 3rd edition criteria for a Class III site. Note
that Class III extreme wind classification is the lowest defined. All wind turbines are designed for a Class
III wind regime.

Temperature, Density, and Relative Humidity
Mountain Village experiences cool summers and cold winters with resulting higher than standard air
density. Calculated air density during the met tower test period exceeds the 1.220 kg/m3 standard air
density for a 44 meter elevation by 6.3 percent. This is advantageous in wind power operations as wind
turbines produce more power at low temperatures (high air density) than at standard temperature and
density.

Wind Speed Scatterplot
The wind speed versus temperature scatterplot below indicates that a substantial percentage of wind at
the Mountain Village met tower site coincides with cold temperatures, as one would expect. However,
during the met tower test periods, temperatures did not fall below -40°C, which is the minimum
operating temperature for arctic-capable wind turbines, and fell below -30°C on just a few occasions.
Colder temperatures may occur during particular severe winters, but it is likely that temperatures colder
than -40°C are extremely rare at the site. Hence, restrictions of wind turbine operations due to extreme
cold should not be expected.
Wind speed/temperature
Mountain Village, Alaska Wind Resource Report Page | 16
Wind Direction
Wind frequency rose data indicates that winds at the Mountain Village met tower site are not especially
directional, although northerly and easterly winds predominate overall. The mean value rose indicates
that easterly and southerly winds, when they do occur, are of high energy and hence likely storm winds.
The wind energy rose indicates that for wind turbine operations the majority of power-producing winds
are from the north-northeast, east, southeast and south. Calm frequency (percent of time that winds at
the 50 meter level are less than 4 m/s) was 17 percent during the met tower test period.
