AVEC would use a project management approach that has been used to successfully design and
construct wind turbines throughout rural Alaska: a team of AVEC staff and external consultants.
AVEC staff and their role on this project includes:
Meera Kohler, President and Chief Executive Office, would act as Project Executive and
would maintain ultimate authority programmatically and financially.
Brent Petrie, Manager, Community Development and Key Accounts, would lead the
project management team consisting of AVEC staff, consultants, and contractors. The
group’s resources include a project coordinator, contracts clerk, accountant, engineer,
and a community liaison.
Debbie Bullock, manager of administrative services, would provide support in
accounting, payables, financial reporting, and capitalization of assets in accordance with
AEA guidelines.
Anna Sattler, community liaison, would communicate directly with Mountain Village
residents to ensure that the community is informed of construction activities.
Resumes for AVEC staff are included in Tab A.
For project delivery, an amalgamated team approach would be utilized. To support the AVEC
team, design consultants and construction managers (CM) would be selected. Both disciplines
are derived from a resource bank of professional firms with applicable histories of performance
in rural Alaska. The construction manager would work concurrently with the design consultant
through design development to provide constructability insight and value engineering to
maximize the overall effectiveness of the final construction documents.
Concurrent with design development, material and equipment procurement packages would be
formulated by the CM in collaboration with AVEC’s purchasing manager. Each package would
be competitively procured or issued from cooperative materials. Purchase orders would be
formulated with delivery dates consistent with dates required for barge or air transport
consolidation. Multiple materials and/or equipment would be detailed for consolidated

Renewable Energy Fund
Grant Application Round 5
AEA 12-001 Grant Application Page 7 of 16 8/26/2011
shipments to rural staging points, where secondary transport to the village destination is
provided. The CM would track the shipments and provides handling services to and around the
destination project sites.
The CM would be responsible for the construction activities for all project components of the
facility upgrade. Local labor forces would be utilized to the maximum extent possible to
construct the projects. Local job training would be provided as a concurrent operation under
the management and direction of the CM. All construction costs, direct and indirect would be
reimbursed on a cost only reimbursement to the CM or paid directly by AVEC.
For the facilities applied for in this application, AVEC is responsible for managing the
commissioning process in content with the CM, designers and vendors. That entails testing and
training of operational personnel, as well as providing for all contract closeout documents.
Selection Process for Contractors:The 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 quarter.
Semi-annual 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.
In general, logistics, construction activities, and weather all contain significant risks. Weather
could delay shipping materials into the community and construction work; however, an
experienced contractor, familiar with Alaskan weather conditions, would be selected. It is
possible that turbines will need to be erected during winter months, and there are risks with
winter work; however, AVEC will select a contractor familiar with winter construction of wind
farms in Alaska. In addition, AVEC routinely purchases Builder’s Risk insurance to mitigate its
exposure to these risks. Advance planning and allowing time for contingencies is crucial to
success in such environments.
SECTION 4 – PROJECT DESCRIPTION AND TASKS
Tell us what the project is and how you will meet the requirements outlined in Section 2 of

the RFA.
The level of information will vary according to phase(s) of the project you propose to
undertake with grant funds.
If you are applying for grant funding for more than one phase of a project provide a
plan and grant budget form for completion of each phase.
If some work has already been completed on your project and you are requesting funding for
an advanced phase, submit information sufficient to demonstrate that the preceding phases
are satisfied and funding for an advanced phase is warranted.
4.1 Proposed Energy Resource
Describe the potential extent/amount of the energy resource that is available.
Discuss the pros and cons of your proposed energy resource vs. other alternatives that may be
available for the market to be served by your project.
Based on a report completed by V3 Energy, the wind resource measured at the Mountain Village
is very good with measured wind power class 5 (excellent). In addition to high average wind
speeds and high wind power density, the site experiences very low turbulence and low extreme
wind speed probability. (See Tab G for entire wind resource report.)
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 diesel power plant in Mountain Village consists of four generators: a Caterpillar
3412 1200 (350 kW), a Caterpillar 3456 (505 kW), a Caterpillar 3412 1800 (601 kW), and a MTU
12V200 (710 kW). These generators were installed in 1984, 2005, 1982, and 2003 respectively.
Aggregate generator efficiency in Mountain Village in 2010 was 14.87 kWh/gal.
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.
The proposed project would add two Northwind 100 wind turbines to the electrical power
system. The anticipated effects are less usage of diesel fuel for electrical power generation.
Between January and December 2010, 191,483 gallons of diesel fuel was consumed to generate
2,847,359 kWh.
Installation of wind turbines in the communities would decrease the amount of diesel fuel used
for power generation. Diesel generator use would be curtailed thereby decreasing generator
operations and maintenance costs and enabling generators to last longer and need fewer
overhauls.
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
Alaska Village Electric Cooperative, Inc.
Mountain Village Wind Construction Project
Renewable Energy Fund
Grant Application Round 5
AEA 12-001 Grant Application Page 9 of 16 8/26/2011
Mountain Village encompasses 4.3 sq. miles of land. The climate is continental with maritime
influences. Temperatures range from -44 to 80 °F. Annual precipitation averages 16 inches, with
snowfall of 44 inches.
In Mountain Village, 26.4 percent of the population is below the poverty line. The median
household income is $49,167 in Mountain Village, which is 25% lower than the State’s median
household income of $$66,712.
The load of is highest during the winter months with the bulk of electricity consumed by
residences and the school. The addition of wind turbines to the electric generation system
would reduce the amount of diesel fuel used for power generation and energy costs would be
stabilized in Mountain Village.
Emergency medical service in Mountain Village is provided by a health aide. Therefore, medical
problems and emergencies must be relayed by telephone or by some other communication
means for outside assistance. Operation of the telephone system requires electricity. Reliable
telephone service requires reliable electric service.
Mountain Village has piped water and sewer systems. Reliable electric service is required for
the continuous operation of the water and wastewater systems and to prevent freezing of the
systems, which will cause extensive damage and interruptions in service.
Like all of Alaska, Mountain Village is subject to long periods of darkness. Reliable electric service
is essential for the operation of home lighting, streetlights, and security lighting. Residents rely
on subsistence resources including salmon, moose, and waterfowl. Subsistence food is gathered
and harvested and stored in refrigerators and freezers. Refrigeration is essential for the
extended storage of perishable foodstuffs, 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.
The addition of two wind turbines to the electric generation system would reduce the amount of
diesel fuel used for power generation and stabilize energy costs in the community.
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

Description of renewable energy technology.Wind power is the renewable energy option of
choice for Mountain Village. Of the wind turbine options available on the market, the “village”
scale turbine size is considered most appropriate for the load profile of the community.
According to its manufacturer, Northern Power of Barre, Vermont, the Northwind 100
represents a new generation of wind turbines. Its permanent-magnet, direct-drive architecture
is the current state of the art for advanced wind turbine design. That architecture overcomes
many of the challenges of connecting old-style induction generators to electrical distribution
grids. The permanent-magnet generator is connected to a full power converter that converts its
variable, low-frequency, alternating-current output to direct current, then back to tightly
regulated alternating current for output to the grid. The permanent-magnet generator requires
no reactive power to energize its magnetic field, removing that influence from the grid. The
power converter allows a broad degree of control over the form and quality of the power output
to the grid. The capacitance and active controls in the power converter allow reactive power to
either be consumed or produced by the Northwind 100 regardless of its real power output, even
in the complete absence of wind. The turbine controls allow power output to be controlled by
dynamic grid conditions, including automatic output reduction or complete shutdown,
regardless of wind conditions. The combination of advanced controls and integrated disk
braking allows gradual ramping of turbine output up or down, minimizing flicker and maximizing
usable power.
AVEC expects two Northwind 100 wind turbines to produce approximately 22% of the electricity
consumed in the villages today. The wind turbines should supply over 612,500 kWh of electrical
energy annually.
Optimum installed capacity.Two Northwind 100 turbines are proposed to operate as a wind-
diesel hybrid power system that would supply wind generated electricity to Mountain Village.
The installed capacity would be 200 kW.
Anticipated capacity factor.HOMER software was used to estimate capacity factor and system
penetration (or renewable fraction) of two NW100 turbines in the power system in Mountain
Village. Using Mountain Village wind data as discussed in section 4.1, at 80% availability the
turbine capacity factor is predicted to be 22%.
Anticipated annual generation.HOMER software estimates wind production with two NW 100
turbines of 612,500 kWh annually (80% turbine availability).
Anticipated barriers.No barriers to successful installation and integration of a wind turbine in
Mountain Village are expected.
Basic integration concept.The integration design concept is comprised of two NW 100 turbines,
a SCADA system to manage the combined operation of the diesel generators and wind turbines,
and remote viewing and system access capability to enable remote monitoring and control of
the wind-diesel hybrid power plant.
Delivery Method.Power generated by the wind turbines would be distributed via the existing

4.3.2 Land Ownership
Identify potential land ownership issues, including whether site owners have agreed to the
project or how you intend to approach land ownership and access issues.
The proposed turbine sites Mountain Village is shown in preliminary design drawings included in
Tab G. On August 16, 2011, AVEC obtained the verbal commitment of the Azachorok
Incorporated in support of this location for a wind farm. AVEC sent the Corporation the lease
agreement on August 23, 2011 and expects to have a signed lease agreement by the end of
August 2011 (Tab G).
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.AVEC is currently seeking a no-hazard determination
from the Federal Aviation Administration. Applications have been submitted for three turbines
and determinations are expected by October 2011.
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 has been initiated for the installation of three turbines. It is expected that AVEC
would receive concurrence from the Service by October 2011.
Clean Water Act (Section 401) Permit:AVEC has initiated the obtaining a wetlands permit from
the U.S. Army Corps of Engineers. It is expected that this permit will be issued by December
2011.
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 is currently being
consulted to ensure that the construction of the wind turbines would have no effect on
threatened or endangered species. Construction would be timed to avoid impacts to migratory
birds in compliance with the Migratory Bird Treaty Act. Mitigation, including annual bird

Renewable Energy Fund
Grant Application Round 5
AEA 12-001 Grant Application Page 12 of 16 8/26/2011
monitoring activities around the wind turbines, is expected.
Wetlands and other protected areas.AVEC is currently applying for a Wetlands permit for the
placement of the access road and pads for the turbines. The project will avoid wetlands as
feasible; however, complete avoidance of wetlands is not possible. It is expected that mitigation
measures for impacts to the wetlands in the project area will include using Best Management
Practices during construction.
Archaeological and historical resources.AVEC has initiated consultation with the State Historic
Preservation Office. A no effect finding is expected by October 2011.
Aviation considerations.AVEC is currently seeking a no-hazard determination from the Federal
Aviation Administration.
Visual, aesthetics impacts.The turbines would be placed near the community of Mountain
Village. Because it is likely that the turbines would be constructed between the communities, it
is likely that there would be little concern for visual or aesthetic impacts. AVEC would conduct
community meetings to discuss the project and visual impacts.
4.4 Proposed New System Costs and Projected Revenues
(Total Estimated Costs and Projected Revenues)

Energy produced from the wind/intertie project would be sold to AVEC’s existing customer base
in the community of Mountain Village. The sales price for the wind generated electricity would
be determined by the Regulatory Commission of Alaska as is done in all AVEC villages. The
delivered cost of energy would be reduced as much as possible for customers within these
communities under current regulations, but that price is expected.
The project has an expected payback of 20 years.

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 possible displacement of diesel fuel used for village
power generation in Mountain Village could be about 47,600 gal/yr and 952,000 gallons over
the project’s 20 year lifetime (assuming 80% turbine availability). This project could save
$231,000 during its first full year of operation (expected to be 2014), with savings increasing
each year, based on rising fuel costs.
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.

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 would empower community
residents and could help avert rural to urban migration.
Once the wind project is constructed, heat recovery systems could be put in place, and costs to
operate important community facilities (e.g. water treatment plants, schools, washeterias, etc.)
would be decreased, enabling managing entities (city governments, tribes, school districts) to
operate more economically.
This project would help with the understanding of the wind resource in western Alaska. Data
acquired from this study assist nearby Yukon-Kuskokwim Delta communities to understand their
wind resource. Data collected from this project could also be used to improve the accuracy of
the State High Resolution Wind Map.
Stabilized energy costs would allow community entities, including the City and Tribe to plan and
budget for important economic, land use, recreation and community service, and environmental
goals listed in the Mountain Village Comprehensive Community Economic Development Plan
(City of Mountain Village, 2002), including elder housing and a cultural center; a youth and day
care center; a lodge and visitors center; dock and industrial site; and a government and business
complex.
Area 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 wind turbines would provide a visual landmark for river, air, and overland travelers, which
would help navigation in the area. Wind turbine orientation and rotor speed would provide
visual wind information to residents.
Running distribution lines out to the wind turbine site would open up additional land for future
electrification.
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.

systems that may be require to continue operation
Commitment to reporting the savings and benefits
As a local utility that has been in operation since 1968, AVEC is completely able to finance,
operate, and maintain this project for the design life. AVEC has capacity and experience to
operate this project. AVEC has operating wind projects throughout the state-familiar with
planning, constructing, operating, and maintaining wind systems.
Business Plan Structures and Concepts which may be considered:The wind turbines would 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 would be funded through ongoing energy sales to the villages that AVEC serves.
Operational issues which could arise:Integration of the SLCs for thermal dump and frequency
controls would need to be addressed. AVEC would use the knowledge gained through the
operations of other village wind-diesel systems to address these issues.
Operating costs:The costs of operations and maintenance would be funded through ongoing
energy sales to the villages that AVEC serves.
Commitment to reporting the savings and benefits:AVEC is fully committed to sharing the
savings and benefits accrued from this project information with their shareholders and sharing
information regarding savings and benefits with AEA.

CRW Engineering Group 2 Project No. 113-95706
St. Marys & Mt Village Wind Turbines
were provided on the plan sheets developed by CRW for Saint Marys dated 08/17/11 and by GPS
coordinates of the met tower site in Mountain Village by AVEC.
3.1 Saint Marys – Wind Turbine Site
Three wind turbines are planned for Saint Marys. The proposed site is south and west of the Pitkas Point
Native Corporation borrow site. The borrow site is located along the road about midway between the
Saint Marys village and airport. The site is located on Pitkas Point Native Corporation land and is the
same location as the previous meteorological tower. The site has generally flat terrain on a gradual,
north-facing slope. Probe refusal was typically met between 1 to 2 feet bgs, inferred to be on bedrock .
Light tundra vegetation covers the site, with some taller brush along drainage areas (north end of site).
There was no visible surface water at the site. An aerial view and typical ground conditions ar e shown in
the attached photos 1 and 2, along with a view of the nearby borrow site in photo 3.
The slope face appears to be well drained, and the ground surface was found to be generally free of
water during the reconnaissance. Regular mounds in a straight alignment were noted in aerial
photography, as well as on the ground. The mounds are aligned along a drainage path that runs
southwest. Probe refusal was observed to be at 2 feet from the top of the mounds. It was noted that a n
easement for a buried line is present in the area.
3.2 Mountain Village – Wind Turbine Site
Two wind turbines are planned for Mountain Village. The preferred site is located along the south side of
the road to Saint Marys about 3 miles east of the Mountain Village airport and 5 miles east of the village.
The site currently has a meteorological tower in place, and is located on a level plateau overlooking the
Yukon River. Typical vegetation includes small tundra grasses, and no tall shrubs were found on site.
Probe refusal was met between 1 to 2 feet bgs on frozen organic soil (peat). A shallow test pit was
advanced near the roadway. The hand probe met refusal at 2.1 feet bgs where the test pit was dug. The
pit revealed frozen peat to the refusal depth.
Several areas around the met tower setup were showing evidence of melting permafrost, which is likely a
result of ground disturbance. The ponded water from degrading permafrost did not appear to be well
drained due to the flat terrain and shallow permafrost. A view of typical ground conditions and ponded
water at the met tower anchors are shown in the attached photos 4 and 5. Access to the site is achieved
via the road to Saint Marys.
4.0 EXISTING LOCAL MATERIAL SOURCES
Three material sources were briefly visited during the reconnaissance. Each of these sites is mining
sedimentary rock of the Nulato Hills formation. The quality of this material needs to be evaluated further if
it being considered for concrete aggregate.
Jeff Stanley 8/24/2011
CRW Engineering Group 3 Project No. 113-95706
St. Marys & Mt Village Wind Turbines
4.1 Saint Marys Borrow Pit
The Saint Marys borrow site is located immediately outside of the community of Saint Marys, on the north
side of the road about 2/3rds of a mile from the village. Sedimentary b edrock is currently mined by
means of ripping and excavation, and is crushed for use. Equipment is on-site to facilitate the crushing
and screening of material. No visible bedrock slopes were observed at the time of the site visit. A bulk
sample was collected from a large stockpile of material that appeared to be crushed and sorted.
4.2 Pitkas Point Borrow Pit
Pitkas Point borrow pit is located approximately 2 miles outside of the community of Saint Marys and is
adjacent to the north of the proposed wind turbine sites. Sedimentary bedrock is currently mined by
means of ripping and excavation, and no blasting has been reported . No screening or crushing
equipment was currently on site. The resource is a highly jointed and bedded, moderately weak
sedimentary rock that is relatively steeply dipping. Overburden appears to be very thin around the
perimeter of the borrow site; commonly ranging from approximately 5 to 10 feet thick, but at some
locations, as thin as 2 feet. Bedrock is overlain by sandy silt to silty sand and organ ic material, with
shrubs above. Bulk samples were collected from a relatively well sorted stockpile with 1 inch material and
from an unsorted stockpile of crushed material.
4.3 Mountain Village Borrow Pit
The Mountain Village borrow pit that is adjacent to the airstrip has been mined for use as gravel pads,
roads, and runways. Based on discussions with the City of Mountain Village, gravel for concrete
construction has been imported several times in recent years, and the local material has not been utilized
for concrete aggregate.
5.0 CONCEPTUAL TOWER FOUNDATIONS
Based on this preliminary information, shallow bedrock is expected at each of the proposed sites. The
depth to bedrock is likely to be within a few feet below the ground surface in Saint Marys and within 5 to
15 ft in Mountain Village.
We understand Northwind 100 turbines are planned, and we have assumed that loading, tower type, and
foundation configuration and dimensioning will be in line with similar past AVEC projects. Based on the
expected conditions, the foundation options most appropriate for these sites are as follows:
Shallow Concrete Mat Gravity Foundation
Shallow Concrete Foundation with Rock Anchors
An evaluation should be made whether cast-in-place or pre-cast concrete is best suited for this site.
Although these are the preferred foundations, other options may be viable, and a more detailed
assessment can be made following a subsurface investigation.

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
construction of an intertie adjacent to the road between Mountain Village and Saint Mary’s, which
would make wind development on the site more advantageous.

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.

Paul,
Per our coordination meeting last week (Tuesday – 8/16/2011), with members from the City of Mt. Village, the Tribal
Council, and the Azachorok Corporation; please find the revised land lease agreement for the proposed Mt. Village Wind
Turbine Project.
The revised agreement appropriately identifies the location that the MET Tower is currently erected and that AVEC was
able to conduct a wind analysis data report from. In addition, I have attached the wind resource report that was
conducted by V3 Consulting… AVEC subcontractor.
Have a great day… hope that everyone catches a lot of fish and harvest a bunch of berries!
Quyana caknek,
