2.4 PROJECT DESCRIPTION
Provide a brief one paragraph description of your proposed project.
Alaska Village Electric Cooperative, Inc. (AVEC) is seeking $5,581,800 from this Grant Program
to construct an electrical intertie between the communities of St. Mary’s and Pilot Station, the
total cost of which is $6,202,000. AVEC will contribute $625,000 cash as its match. The intertie
will be designed with 14 miles of new connection through undeveloped terrain. The completed
design work-to-date indicates the three-phase electrical intertie will require two river crossings
and six slough/lake crossings, must be constructed in winter months, and will need pole spacing
of 185 feet. Completed design work on the intertie is included in Tab F.
At present, St. Mary’s and Pitka’s Point are connected by a distribution power line, but Pilot
Station is a stand-alone, diesel-powered community. This project would connect the electric
system of Pilot Station to the St. Mary’s/Pitka’s Point system. Standby generation capability will
be provided with a new standby generation module in Pilot Station, but primary generation will
be delivered by the existing St. Mary’s power plant and an EWT wind turbine.
Another Round 6 Renewable Energy Grant Program application requests funding to build a
wind energy system for the intertied communities of St. Mary’s and Pitka’s Point. This project
will add Pilot Station, about eleven miles from St. Mary’s, to that proposed wind system.
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.)
Renewable Energy Fund Round 6
Grant Application
St. Mary’s / Pilot Station Wind Energy Intertie Construction
AEA13-006 Grant Application Page 4 of 24 7/3//2012
This project would help stabilize the existing high energy costs in Pilot Station by avoiding the
costs of a new power plant and associated tank farm. The St. Mary’s Wind Power Conceptual
Design Analysis Report says, “Airspace restrictions around Pilot Station preclude the option of
wind turbines for the village, but with an intertie, the wind power project plan for St. Mary’s
will be available to also serve Pilot Station. Although the intertie itself is projected to cost $5.95
million), the net cost of the intertie, with avoided capital costs considered, is a very modest
$260,000.” (Note, this has been updated to $6.2 million, but the benefits remain large.)
This project would stabilize energy cost for households in Pilot Point, St. Mary’s, and Pitka’s
Point by sharing the benefits of a wind project between the three communities. The EWT
turbine installation proposed in St. Mary’s/Pitka’s Point would be able to be fully exploited to a
greater potential. The costs of power generation via diesel generation would also be shared
among three communities, helping to stabilize energy costs.
In addition, this project would reduce overall operations and maintenance costs. By shifting to
only a stand-by power plant in Pilot Station, AVEC will save approximately $170,000 per year in
labor, generator consumables, and replacement parts in Pilot Station.
Finally, this project would reduce pollution and greenhouse gas emissions, and the overall
contribution to global climate change by eliminating a separate power plant in Pilot Station and
by employing more of the proposed wind turbine’s output to serve the larger electric loads of
the intertied communities than would be the case for St. Mary’s/Pitka’s Point alone .
Please see Section 5: Project Benefits for additional details.
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.
AVEC is proposing a project to construct an electrical intertie between the communities of St.
Mary’s and Pilot Station. The estimated construction cost is $6,202,000. AVEC requests
$5,581,800 from the State of Alaska through a Renewable Energy Fund award for this
construction project. AVEC will provide $620,200 cash (10% of the total costs) as a match
contribution. The land necessary for this project and grant administration are additional
contributions to this effort.

For the proposed facilities, AVEC is responsible for managing the commissioning process in
concert 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/Vendors: The construction contractor/vendor selection will
be made from a pre-qualified list of contractors/vendors with a successful track record with
AVEC. Pre-qualified contractors/vendors have been selected based upon technical
competencies, past performance, written proposal, quality, cost, and general consensus from
an internal AVEC technical steering committee. The selection of contractors/vendors would
occur in strict conformity with AVEC’s procurement policies, and conformance with OMB
circulars.
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 2011, AVEC
successfully met reporting requirements for 16 state and 19 federal grants. An independent
financial audit and an independent auditor’s management letter completed for AVEC for 2011
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 Community Development Department. For financial
reporting, the Community 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 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, combined, and supplemented as necessary
and forwarded as one report to the AEA project manager each quarter.
Quarterly face-to-face meetings will occur between AVEC and AEA to discuss the status of all
projects funded through the AEA Renewable Energy Fund 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.
AVEC recognizes and makes plans to avoid major consequences for falling behind schedule on
this project. Since construction has specific windows it must comply with (e.g., placement of
poles in this project must be done in th e winter when the ground is frozen.); missing upfront
tasks like ordering parts and assigning labor could play havoc with the schedule. The project
could be delayed an entire year if the tasks are not completed on time.
Weather could delay shipping materials into the community; weather can impact the
construction schedule. However, an experienced Alaskan contractor, expecting bad weather, will
be selected and will be prepared for weather-related problems.
AVEC is responsible to its member communities and a board of directors, and provides a cash
match; therefore, staying on schedule and within budget is essential. This project will result in
decreasing electricity costs, and AVEC’s member communities are very interested in this project
because energy costs can be a large portion of their budgets. AVEC member communities expect
status updates on village projects including when and what work will occur, who will be involved,
and when it will be completed. If work does not occur according to the schedu le, AVEC’s CEO
and Board of Directors are usually alerted by member communities, and there are repercussions.
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.
Another Round 6 Renewable Energy Fund application requests funding to add a wind turbine to
St. Mary’s/Pitka’s Point existing energy generation system. This project will construct an intertie
between Pilot Station and the planned new wind energy system in St. Mary’s/Pitka’s Point to
take advantage of the wind energy.
The wind resource measured at the St. Mary’s/Pitka’s Point site is outstanding with measured
wind power a Class 6 by measurement of wind power density and wind speed. Extensive wind
Renewable Energy Fund Round 6
Grant Application
St. Mary’s / Pilot Station Wind Energy Intertie Construction
AEA13-006 Grant Application Page 10 of 24 7/3//2012
resource analysis has been conducted in the St. Mary’s region, with met towers at a lower
elevation site closer to the village of St. Mary’s, one near Mountain Village, and one near Pitka’s
Point. Documented in St. Mary’s Area Wind Power Report by V3 Energy, LLC, dated July 20,
2010, the wind resource measured at the nearby St. Mary’s met tower site is less robust than
that measured at Pitka’s Point, and appears to experience similar icing problems. Considering
the inland location of St. Mary’s/Pitka’s Point, the wind resource measured at the Pitka’s Point
met tower site is highly unusual and very favorable, with its combination of a high annual
average wind speed, relatively low elevation, likely good geotechnical conditions, and proximity
to existing roads and infrastructure. See Tab F for more information.
The Pitka’s Point wind resource is comprehensively described in Pitka’s Point, Alaska Wind
Resource Report by V3 Energy, LLC, dated April 25, 2012 (Tab F).
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 Pilot Station consists of one Cummins 397 kW (installed in
1998), one Cummins 499 kW (installed in 2005), and one Detroit Diesel 324 kW (installed in
2002). Pilot Station’s power plant produced 1,770,301 kWh in 2011 using 134,999 gallons of
diesel. Aggregate generator efficiency in Pilot Station in 2011 was 13.06 kWh/gallon. The peak
load was 381 kW (in December) with an average load of 202 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 Pilot Station is 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 fue l for transportation needs.
Another Round 6 proposed project would add one EWT wind turbine to the St. Mary’s/Pitka’s
Point electrical power system. This project would intertie Pilot Station to energy generation via
the new turbine, and to the existing power plant in St. Mary’s. The anticipated effects are
reduced consumption of diesel fuel for electrical power generation, and less usage of heating
fuel for boiler operations through dispatch of excess electrical energy to selected heating loads.
Greatly reduced diesel generator use would decrease generator operation and maintenance
costs, enabling generators to last longer and need fewer overhauls.
The existing power plant in Pilot Station is old and at risk for flooding. With this new intertie ,
the Pilot Station power plant could be decommissioned. A new back-up generator would be
installed in Pilot Station should the intertie be offline for any reason.

4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
Pilot Station is located on the northwest bank of the Yukon River, about 11 miles east of St.
Mary's on the Yukon-Kuskokwim Delta. The climate is maritime, averaging 60 inches of snowfall
with 16 inches of precipitation per year. Temperatures can range from -44 to 83 °F. The Lower
Yukon is ice-free from mid-June through October.
Currently, Pilot Station has a stand-alone, electric power system with no intertie or connection
beyond the village itself. The total electricity generated in Pilot Station in 2011 was 1,770,301
kWh. The load is highest during the winter months (peak use was 381 kW), when the
community experiences heavy winds and extended periods of darkness. The addition of the
wind turbines (from another Round 6 application) to the electric generation system (from this
application) could reduce the amount of diesel fuel used for power generation.
An intertie connecting to the wind project in St. Mary’s will enable the EWT turbine installation
proposed in St. Mary/Pitka’s Point to be exploited to a greater potential. The costs of power
generation via diesel generation will also be shared among three communities, thereby helping
to stabilize energy costs.
An isolated village, Pilot Station is only accessible by airplane, barge, snowmachine or small
boat, and so relies mainly on air transportation, especially for delivery of medical goods and the
transport of sick or injured individuals, or mothers nearing childbirth. Reliable electric service is
essential to maintaining vital navigation aids for the safe operation of aircraft; runway lights,
automated weather observation stations, VASI lights, DMEs and VORs (aircraft navigation
systems) are all powered by electricity. This project will increase efficiencies and stabilize the
costs of the energy system in Pilot Station.
Emergency medical service is provided in the health clinic by a health aide. Medical problem s
and emergencies must be relayed by telephone or by some other communication means for
outside assistance. Tele-medicine is rapidly growing in rural Alaska as a means of regular and
emergency care, as winter conditions sometime impede air transport and ac cessibility. Reliable
telephone service and tele-medicine require reliable and affordable electric service.
Like all of Alaska, Pilot Station is subject to long periods of darkness in the winter. Reliable and
affordable electric service is essential for the operation of home lighting, streetlights, and
security lighting. Residents rely on subsistence resources including salmon, moose, bear, 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
reducing maintenance and operations costs.

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
AVEC is requesting funding to design and construct an intertie between Pilot Station and St.
Mary’s. The primary purpose of the intertie is to connect Pilot Station to the proposed St.
Mary’s wind energy project (see separate round 6 application). Doing so is projected to reduce
fuel consumption on the order of 30,000 gallons/year and will also reduce power plant
emissions. Additional benefits of the intertie would include;
The ability to power both communities from a centralized power plant in St Mary’s. This
would improve generation efficiency and reduce O&M costs on the order of
$250,000/year.
Avoidance of the replacement cost (approximately $7.9 million) for a new power plant
and bulk fuel facility in Pilot Station. The existing facilities have been damaged by past
flood event and are nearing the end of their useful lives.
The intertie as currently designed would begin at the northeast end of the existing power
distribution system in St. Mary’s, travel west for approximately 4 miles, then southeast for
another 10 miles, looping around the east end of the new airport planned for Pilot Station.
Construction of the intertie would include the installation of 14 miles of 3 -phase overhead
power line including;
Two river crossings, one across the Andreafsky River approximately 2 miles north of St
Mary’s, and the second one across the East Fork of the Andreafsky River near the
midpoint of the intertie. The first crossing would be on the order of 1500 feet in length
and the second one approximately 600 feet.
Six slough/lake crossings varying in length from 260 feet to 600 feet.
The entire alignment with the exception of the connection points in St Mary’s and Pilot Station
will be constructed through undeveloped terr ain. Typical line poles will be spaced approximately
185 feet apart. Poles in the relatively flat wetland areas will be pile supported. Poles in the hilly
upland areas will most likely be direct set. Because of the wet terrain and limited access, the
project would be constructed during the winter. AVEC, using funding from The Denali

2013. Completed design work on the intertie is included in Tab F.
Renewable Energy Technology. The intertie would not have an installed capacity of annual
generation; however, the intertie would connect to a 900 kW 52-900 EWT planned to be
installed near Pitka’s Point.
Optimum installed capacity/Anticipated annual generation. The EWT turbine, at 80% wind
turbine availability (6.75 m/s mean wind speed) would produce 2,483,000 kWh annually, once
connected to Pilot Station. (This is even higher generation than if the turbine where serving St.
Mary’s/Pitka’s Point alone.) The intertied electrical load would be 6,058,000 kWh/year. The
capacity factor would be 34.5%. Wind generation could be increased once the system is
connected to Mountain Village. (See separate Round 6 application.)
Anticipated barriers. No unique barriers to successful construction of the intertie are expected.
Basic Integration Concept. This intertie project includes upgrades in St. Mary’s and Pilot Station
to tie into the existing power systems. AVEC is currently developing the integration concept for
the wind turbine with the St. Mary’s power plant, which will be completed by the end of 2012.
Delivery methods. The project will connect to the existing power lines in Pilot Station and St.
Mary’s.
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.
AVEC has held a number of meetings regarding the project with community members and
representatives from the cities, villages, and the Native Corporations of Pilot Station and St.
Mary’s. Land owners (the corporations) have been provided with draft zone easements, and
have meetings scheduled in September 2012 to review and approve them. Copies of the
unsigned zone easements are included under Tab F.
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
It is likely that the following permits would be needed to construct the intertie:
Federal Aviation Administration Determination of No Hazard to Air Traffic
Section 404 Permit (Wetlands Permit) from the U.S. Army Corps of Engineers
Renewable Energy Fund Round 6
Grant Application
St. Mary’s / Pilot Station Wind Energy Intertie Construction
AEA13-006 Grant Application Page 14 of 24 7/3//2012
Consultation with U.S. Fish and Wildlife Service
.
AVEC will submit permit applications in October 2012, and expect to have permits in hand by
the end of 2012. There are no barriers identified for the successful permitting of this project.
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. According to the U.S. Fish and Wildlife Service, Anchorage
Field Office, Section 7 Consultation Guide, there are no endangered or listed species, or
federally designated critical habitat areas listed between St. Mary’s and Pilot Station.
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. It is likely that the intertie poles would be placed in
designated wetland locations. An U.S. Army Corps of Engineers’ wetlands permit would be
needed.
Archaeological and historical resources. Compliance with the National Historic Preservation
Act with the State Historic Preservation Officer would be conducted prior to construction of the
intertie.
Land development constraints. AVEC is acquiring a zone easement for the intertie.
Corporation land owners are currently reviewing the easement language.
Aviation considerations. A Federal Aviation Administration Determination of No Hazard to Air
Traffic would be sought for the installation of the poles near the airports in both communities.
Because the intertie would be constructed between the communities, it is likely that there
would be very little concern for visual or aesthetic impacts. AVEC would conduct community
meetings to discuss visual impacts and how they could be minimized, in the unlikely event that
visual issues arise.

the project. Cost information should include the following:
Total anticipated project cost, and cost for this phase
Requested grant funding
Applicant matching funds – loans, capital contributions, in-kind
Identification of other funding sources
Projected capital cost of proposed renewable energy system
Projected development cost of proposed renewable energy system
AVEC is seeking $5,581,800 from this Grant Program to construct a 14 mile electrical intertie
between Pilot Station and St. Mary’s. AVEC would provide $620,200 as a cash match
contribution. The total cost of the intertie is $6,202,000.
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.)
Intertie operating and maintenance costs are expected to be approximately $20,000/year. The
costs of operations and maintenance would be funded through ongoing energy sales to AVEC’s
customers (member owners) in the villages.
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
Energy produced from the proposed wind project and carried to Pilot Station through this
proposed intertie project would be sold to AVEC’s existing customer base in the communities of
Pilot Station and St. Mary’s/Pitka’s Point. 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. Currently, of AVEC’s 55 villages, those with wind power
systems experience the lowest electricity cost of within the utility. Similar energy cost

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

energy subsidies or programs that might be available)
Discuss the non-economic public benefits to Alaskans over the lifetime of the project
Renewable Energy Fund Round 6
Grant Application
St. Mary’s / Pilot Station Wind Energy Intertie Construction
AEA13-006 Grant Application Page 19 of 24 7/3//2012
Potential Annual Fuel Displacement. Considering the intertie alone, the enhanced
power plant efficiency would likely be offset by intertie power losses; however, if you
consider a scenario in which Pilot Station and St. Mary’s are served by separate wind
systems, positive benefits of an intertie are apparent. Approximately 68,900 more
gallons of fuel would be displaced for power generation with an intertie connecting to
an EWT turbine in St. Mary’s compared to Pilot Station being served by three (3)
Northwind 100s, and St. Mary’s being served by three (3) Northwind 100s.
Anticipated Annual Revenue. This project by itself would not produce revenue.
Non-economic Public Benefits. In St. Mary’s and Pilot Station the average annual price
for residential electricity for the calendar year 2011 was $0.5902 per kilowatt hour
(kWh), which far exceeds the national benchmark of $0.264/kWh. The average annual
residential cost of electricity per household in 2011 was $4,197.18. According to the
2010 Census, 15.6% of St. Mary’s residents and 26.5% of Pilot Station residents had
incomes below the poverty level. The median household income in St. Mary’s was
$38,000 and, in Pilot Station, it was $37,917. The poorest residents in rural Alaska,
including St. Mary’s and Pilot Station, pay almost half their household incomes for home
energy costs, according to a study by the Institute of Social and Economic Research.
Furthermore, these households use less than half as much energy as those whose power
comes from natural gas or hydro-electric sources. This project, as well as this
Renewable Energy Program, is part of the solution to the difficult costs of living rural
Alaska.
The project would reduce diesel exhaust emissions and noise in Pilot Station by allowing
the retirement of a diesel power plant and tank farm (with other financing). Wind
generation in St. Mary’s will also offset diesel exhaust produces when diesel fuel is used
for power generation.
The community facilities such as the school and homes are connected to a piped water
and sewer system. Reliable and affordable electric service is required for the continuous
operation of the water and wastewater systems, and to prevent freezing of those
systems, which would cause extensive damage and interruptions in service.
Poor efficiency is a problem that continues to plague small, remote villages that lack an
economic structure to support utilities. In many communities across the country, small
and large businesses -- and perhaps industrial facilities-- pay a larger share of utility
costs than do residential users. In doing so, they help pay for the necessary upgrades
and improvements. Some Alaskan communities have seafood processing pla nts or
tourist facilities that pay a larger share of the utility’s costs. But many Alaskan villages,
including these two, have only state and federal programs , and their own-- many times
very poor -- households to rely on to operate and maintain what they can, and--in rare
cases--expect to build for the future.

Approximately 54 Pilot Station residents commercial fish, which is a part-time job at
best. However, these proud communities have a strong Native culture , and residents
desire to maintain their communities and way of life which revolves around hunting,
fishing and other subsistence activities, as well as arts and crafts production. This
project will support their goal.
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
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 the capacity and experience to
operate this project. AVEC has experience in designing, constructing, operating and maintaining
energy systems throughout rural Alaska, including intertie projects. Past successful design and
construction projects include fully functional interties between Toksook Bay and Tununak,
Toksook Bay and Nightmute, and Emmonak and Alakanuk.
Business Plan Structures and Concepts which may be considered: The intertied systems 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 AVEC’s consumers (member
owners) in the villages.
Operational issues which could arise: AVEC will use the knowledge gained through the
operations of other intertied systems to address any operational issues that might arise.
Operating costs: The operational costs are expected to be around $20,000/year.
Commitment to reporting the savings and benefits: AVEC is fully committed to sharing the
savings and benefits accrued from this project information with its member-owners , and 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
Renewable Energy Fund Round 6

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.
Work under this grant award will be initiated immediately. Once funding is known to be
secured, AVEC will prepare and sign contracts with its contractors.
With Denali Commission funding, AVEC installed met towers and completed wind studies
between 2007 and 2009 at two locations between St. Mary’s and Pitka’s Point. AVEC also used
their own funding to examine possible intertie routes to Mountain Village and Pilot Station. This
project is the next logical step in energy infrastructure development in the area.
Final design and permitting work has been funded by the Denali Commission and AVEC’s cash
match, and is presently underway. AVEC expects this work to be completed well before the
announcement of grant awards under this Round 6. Land use agreements are also underway,
and this application will likely be updated with all necessary land documents.
SECTION 8– LOCAL SUPORT
Discuss what local support or possible opposition there may be regarding your project. Include
letters of support from the community that would benefit from this project.
This project has the full support of St. Mary’s and Pilot Station lea dership. Please see the
attached letters of support in Tab B.
SECTION 9 – GRANT BUDGET
Tell us how much you want in grant funds Include any investments to date and funding sources,
how much is being requested in grant funds, and additional investments you will make as an
applicant.
AVEC plans to construct an intertie between Pilot Station and St. Mary’s. This work would cost
$6,202,000. AVEC requests $5,581,800 from AEA and will provide $620,200 as a cash
contribution. A detail of the grant budget follows.
AVEC, with Denali Commission funding, will complete final design and permitting of this project.
To date the work on this project has involved a geotechnical survey, route alternative analysis,
and cost estimations. This fall AVEC will obtain LIDAR for the intertie route. Design and
permitting will be completed by May 2013.

!Subject:!Intertie Alignment Reconnaissance
!!St Marys - Mountain Village - Pilot Station
!!Reference: 4253.008
Duane Miller Associates (DMA), with representatives of STG, Inc. and
Errico Electrical Engineering LLC, conducted a helicopter reconnaissance along
the proposed powerline interties between St. Marys and Mountain Village and
St. Marys and Pilot Station on October 9, 2009. The purpose of the work was to
conduct an aerial reconnaissance of the proposed alignment(s) developed for
AVEC between these villages. The proposed intertie alignments were developed
from base maps, images, and aerial photography with limited ground truthing.
The reconnaissance flights were conducted to observe the proposed intertie
routes and to locate potential alternate routes, if feasible. Based on the
reconnaissance level assessment, the inferred geology and recommendations for
additional field assessment along the intertie route(s) are summarized below.
The aerial reconnaissance was conducted with a Bell Jet Ranger helicopter
from Yukon Helicopters of Bethel. At the the time of the flights, no snow cover
was present and weather was generally light overcast with good visibility.
Summary reconnaissance findings and conceptual-level geologic and
geotechnical engineering considerations for the St. Marys to Mountain Village
and the St. Marys to Pilot Station alignments are provided separately. All
proposed alignments will require land status assessment, in particularly
corporation lands and allotments. Determination of land ownership along the
reconnaissance alignments was not conducted under this scope of services.
St. Marys to Mountain Village Powerline Intertie Alignment
The proposed St. Marys to Mountain Village alignment roughly follows the
existing gravel roadway between the villages, Plate 1. The existing gravel
accessway with additional tundra protection at required areas may allow for
summer intertie construction. The existing roadway generally follows higher,
better drained topography but crosses surface drainages, ponded wet areas, or
other lower lying areas along the alignment. The powerline alignment may cross
undisturbed areas to reduce length along the existing roadway curves.
In general, one significant surface drainage crossing was noted along the
existing roadway, as noted on Plate 1, along with other culvert and smaller
surface drainage areas along the alignment. In addition, the roadway is north of
the existing Mountain Village airstrip, which may pose an airspace restriction
requirement for an overhead powerline. An alternative may be to route the
powerline south of the airstrip through a lower topographic area.
Existing site-specific geotechnical information was not available for the
existing roadway. In general, the alignment should be suitable for a conventional
pile supported powerline intertie. However, the general geology in St. Marys
and Mountain Village indicates a variable thickness of icy silt and frozen organic
soil is present over bedrock in the area. Bedrock is generally shallow and may
limit pile embedment depths. A shallow pile embedment may result in frost
jacking if a driven pile foundation is being considered for the powerline intertie.
In general, driven pile embedments on the order of 40 feet are typically
recommended in the Yukon Kuskokwim region to resist seasonal frost uplift.
Lateral loads, particularly along powerline tangent points will need to be
determined for guy anchor design to resist longer-term creep deformation in icy
soil. Areas with the potential for deeper surface thaw, such as stream crossings
and areas subject to deeper winter snow drifting, may be experiencing
permafrost degradation. These areas may pose specific geotechnical engineering
challenges.

Draft Letter for AVEC Review, December 23, 2009
St. Marys to Pilot Station Powerline Intertie Alignment
AVEC developed a preliminary alignment for the St. Marys to Pilot Station
intertie, denoted as the red lined alignment presented on Plate 2. Based on the
overflight alignments, three general terrains were noted.
First, the upland area around Pilot Station was observed. The upland areas
are generally well-drained, hilly areas with established ATV or snowmachine
trails. The upland area from Pilot Station is well defined with multiple ridges and
accessways opportunities toward St. Marys. The AVEC alignment portion near
Pilot Station is near the airstrip. An alternate route near the village water tank
may reduce airspace conflicts.
A similar upland area was identified near St. Marys along the north side of
the Andreasfsky River. If feasible, an alternative alignment along the north side
of the river would reduce the length within the wetter lowland area and appears
to reduce both the span and number of river crossings. The general location of
the alternative alignment is denoted as the dark blue and green flight lines
presented on Plate 2.
The geology of these upland areas is undefined but is expected to be icy
soils overlying relatively shallow bedrock. As with the Mountain Village
alignment, shallow bedrock, if present, may impact pile embedment depth
required to control seasonal frost heave.
The second terrain is a lowland area between the upland area near Pilot
Station and St. Marys. From the upland area near Pilot Station toward St. Marys,
the topography slopes to a lowland area with numerous lakes and drainages.
The lowland area is expected to have thicker sediments over bedrock. These
areas are also expected to have degrading permafrost and possibly thicker
organic sequences, particularly along oxbows. Careful routing through the
lowland area is recommended, with attempts to keep the intertie along higher
ground as best possible.

Draft Letter for AVEC Review, December 23, 2009
The final terrain will be the river crossings. Depending on the final
alignment, at least two larger river crossing will be required. These crossings
will most likely be overhead.
The alternate alignments noted on Plate 2 will increase the intertie distance.
However, the alternative alignments result in a reduced overall cost and
improved reliability if the intertie foundations are located along upland areas. In
addition, if the powerline intertie can be founded on taller towers to permit
longer spans, the lowland and river crossing area may be traversed with greater
long-term reliability.
The depth to bedrock and geotechnical conditions (soil and thermal states)
along the lowland areas should be determined as part of the engineering
evaluation. If larger towers are being considered for the river spans and the
lowland areas, pile groups may be feasible. Site-specific geotechnical
assessments should be considered at the tower sites, if taller structures are
planned.
If you have any questions on our findings or recommendations, please

Introduction
Alaska Village Electric Cooperative (AVEC) is the electric utility for the City of Saint Mary’s/Andreafsky as
well as the interconnected village of Pitka’s Point. AVEC was awarded a grant from the Alaska Energy
Authority (AEA) to complete feasibility and design work for installation of wind turbines, with planned
construction in 2014.
Wind resource studies of the St. Mary’s area began in 2007 with identification of possible wind turbine
sites on Pitka’s Point Corporation land and Saint Mary’s corporation land, located relatively near each
other between the villages of Saint Mary’s and Pitka’s Point. Both sites were equipped with 40 meter
met towers, but the Pitka’s Point site eventually proved to have the superior wind resource and was
chosen as the primary site for conceptual design and feasibility work.
CRW Engineering Group, LLC was contracted by AVEC to develop a conceptual design report and design
package for a wind turbine project in Saint Mary’s. This analysis is a component of that larger effort.
Synopsis of Economic Modeling Results
Three wind turbine options were modeled for energy balance and economic benefit and cost with
Homer software.
• Configuration 1 considers three Northern Power 100 turbines serving only the Saint Mary’s
electrical and thermal load.
• Configuration 2 serves the same load, but substitutes one EWT 52-900 turbine in place of the
Northern Power turbines.
• Configuration 3 maintains use of the EWT turbine, but adds the Pilot Station electrical load via
construction of an intertie.
Basic economic modeling results are presented in the table below.

Village of St. Mary’s/Andreafsky
St. Mary's is located 450 air miles west-northwest of Anchorage on the north bank of the Andreafsky
River, five miles from its confluence with the Yukon River. The City of St. Mary's encompasses the Yupik
villages of St. Mary's and Andreafsky. St. Mary's is a Yupik Eskimo community that maintains a fishing
and subsistence lifestyle. The sale of alcohol is prohibited in the city. According to Census 2010, 507
people live in St. Mary’s and Andreafsky. There are 209 housing units in the community and 151 are
occupied. Its population is 91.5 percent Alaska Native, 3.8 percent Caucasion, and 4.7 percent multi-
racial.
Saint Mary’s, Alaska Wind Power Conceptual Design Analysis Page | 2
Water is derived from Alstrom Creek reservoir and is
treated. Most homes in the village have complete plumbing
and are connected to the piped water and sewer system.
Waste heat from the power plant supports the circulating
water system. A 1.7-million-gallon sewage lagoon provides
waste treatment. A washeteria is available nearby at Pitka's
Point. An unpermitted landfill is shared with Pitka's Point.
Electricity is provided by AVEC with interconnection to the
village of Pitka’s Point and the St. Mary’s airport (station
code KSM). There is one school located in the community, attended by 185 students. There is a local
health clinic staffed by a health practitioner and four health aides. Emergency Services have river,
limited highway, and air access.
Wind Resource at Pitka’s Point and Saint Mary’s
The wind resource measured at the Pitka’s Point met tower site is outstanding with measured wind
power class 6 by measurement of wind power density and wind speed. Extensive wind resource analysis
has been conducted in the Saint Mary’s region, with met towers at a lower elevation site closer to the
village of Saint Mary’s and near Mountain Village, in addition to the Pitka’s Point met tower.
Documented in Saint Mary’s Area Wind Power Report by V3 Energy, LLC, dated July 20, 2010, the wind
resource measured at the nearby Saint Mary’s met tower site is less robust than that measured at
Pitka’s Point and appears to experience similar icing problems. The Mountain Village wind resource is
very good as well with mean wind speed near that measured at Pitka’s Point. Considering the inland
location of Saint Mary’s/Pitka’s Point, the wind resource measure at the Pitka’s Point met tower site is
highly unusual, and very favorable, with its combination of a high annual average wind speed, relatively
low elevation, likely good geotechnical conditions, and proximity to existing roads and infrastructure.
A 40 meter NRG Systems, Inc. tubular-type meteorological (met) tower was installed on Pitka’s Point
Native Corporation land on the bluff immediately above the Yukon River with excellent exposure to
northeasterly winds down the Andreafsky River, northerly winds from the mountains and southerly
winds from the flat, tundra plains leading toward Bethel. The met tower site is near an active rock
quarry and visual inspection of that quarry indicates the likelihood of excellent geotechnical conditions
for wind turbine foundations. Also of advantage for the site is near proximity of the road connecting
Saint Mary’s to Pitka’s Point, the airport and Mountain Village. A two-phase power distribution line
(connecting the St. Mary’s powerplant to Pitka’s Point as one phase and to the airport as the second
phase) routes on the south side of the road. This line could be upgraded to three-phase at minimal cost
to connect wind turbines to three-phase distribution in Saint Mary’s.
The Pitka’s Point wind resource is comprehensively described in Pitka’s Point, Alaska Wind Resource
Report by V3 Energy, LLC, dated April 25, 2012.

Wind Speed
Anemometer data obtained from the met tower, from the perspectives of both mean wind speed and
mean wind power density, indicate an outstanding wind resource. Note that cold temperatures
contributed to a higher wind power density than standard conditions would yield for the measured
mean wind speeds.

Time series calculations indicate high mean wind speeds during the winter months with more moderate,
but still relatively high, mean wind speeds during summer months. This correlates well with the Saint
Mary’s/Andreafsky/Pitka’s Point village load profile where winter months see high demand for
electricity and heat and the summer months have lower demand for electricity and heat. The daily wind
profiles indicate relatively even wind speeds throughout the day with slightly higher wind speeds during
night hours.

Extreme Winds
A modified Gumbel distribution analysis, based on monthly maximum winds vice annual maximum
winds, was used to predict extreme winds at the Pitka’s Point met tower site. Sixteen months of data
though are minimal at best and hence results should be viewed with caution. Nevertheless, with data
available the predicted Vref (maximum ten-minute average wind speed) in a 50 year return period (in
other words, predicted to occur once every 50 years) is 41.6 m/s. This result classifies the site as Class II
by International Electrotechnical Commission 61400-1, 3rd edition (IEC3) criteria. IEC extreme wind
probability classification is one criteria – with turbulence the other – that describes a site with respect to
suitability for particular wind turbine models. Note that the IEC3 Class II extreme wind classification,
which clearly applies to the Pitka’s Point met tower site, indicates relatively energetic winds and
turbines installed at this location should be IEC3 Class II rated.

Wind Direction
Wind frequency rose data indicates that winds at the Pitka’s Point met tower site are primarily bi-
directional, with northerly and east-northeasterly winds predominating. The mean value rose indicates
that east-northeasterly winds are of higher intensity than northerly winds, but interesting, the
infrequent south-southeasterly winds, when they do occur, are highly energetic and likely indicative of
storm winds.
Wind frequency rose (38 m vane) Wind energy rose (38 m anem.)
Temperature and Density
The Pitka’s Point met tower site experiences cool summers and cold winters with resulting higher than
standard air density. Calculated annual air density during the met tower test period exceeds the 1.204
kg/m3 standard air density for a 177 meter elevation by 5.7 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-Diesel System Design and Equipment
Wind-diesel power systems are categorized based on their average penetration levels, or the overall
proportion of wind-generated electricity compared to the total amount of electrical energy generated.
Commonly used categories of wind-diesel penetration levels are low penetration, medium penetration,
and high penetration. The wind penetration level is roughly equivalent to the amount of diesel fuel
displaced by wind power. Note however that the higher the level of wind penetration, the more
complex and expensive a control system and demand-management strategy is required. This is a good
compromise between of displaced fuel usage and relatively minimal system complexity and is AVEC’s
preferred system configuration. Installation of three Northern Power 100 wind turbines or one
EWT52/54-900 wind turbine at the Pitka’s Point would be configured at the medium penetration level.

Diesel generator(s) run full time at greater than minimum

automatic generator start, stop and paralleling. To control
system frequency during periods of high wind power input,
system requires fast acting secondary load controller
matched to a secondary load such as an electric boiler
augmenting a generator heat recovery loop. At high wind
power levels, secondary (thermal) loads are dispatched to
absorb energy not used by the primary (electric) load.
Without secondary loads, wind turbines must be curtailed
to control frequency.

and possibly additional components such as demand-
managed devices.

sources, such as diesel generators, wind turbines, solar panels, batteries, etc. and is widely used to aid
development of Alaska village wind power projects.
Diesel Power Plant
Electric power (comprised of the diesel power plant and the electric power distribution system) in Saint
Mary’s is provided by AVEC. The existing power plant in Saint Mary’s consists of one Cummins diesel
generator model QSX15G9 rated at 499 kW output, and two Caterpillar diesel generators, a model 3508
rated at 611 kW output and a model 3512 rated at 908 kW output.

Wind Turbines
This report considers installation of three Northern Power 100 ARCTIC turbines for 300 kW installed
wind capacity to serve only the Saint Mary’s load, or one EWT 52-900 for 900 kW installed wind capacity
to serve Saint Mary’s initially but then both Saint Mary’s and Pilot Station upon completion of the
intertie, which can be considered a companion project. With capacity considerations, three Northern
Power 100 turbines best match the St. Mary’s load while the EWT52-900 turbine, given its much higher
energy output, works best when serving an intertied St. Mary’s-to-Pilot Station load.
Northern Power 100 ARCTIC
The Northern Power 100 ARCTIC, formerly known as the Northwind 100 (NW100) Arctic, is rated at 100
kW and is equipped with a permanent magnet, synchronous generator, is direct drive (no gearbox), and
is equipped with heaters and has been tested to ensure operation in extreme cold climates. The turbine
has a 21 meter diameter rotor operating at a 37 meter hub height. The turbine is stall-controlled and in
the proposed version will be equipped with an arctic package enabling continuous operation at
temperatures down to -40° C. The Northern Power 100 ARCTIC is the most widely represented village-
scale wind turbine in Alaska with a significant number of installations in the Yukon-Kuskokwim Delta and
on St. Lawrence Island. The Northern Power 100 ARCTIC wind turbine is manufactured in Barre,
Vermont, USA. More information can be found at http://www.northernpower.com/. The turbine
power curve is shown below.
Northern Power 100 ARCTIC power curve
Saint Mary’s, Alaska Wind Power Conceptual Design Analysis Page | 9
EWT52-900
The EWT52-900 is an IEC Class II-A wind turbine rated at 900 kW, equipped with a direct drive,
permanent magnet, synchronous generator, a 52 meter diameter rotor, and 40, 50 or 75 meter high
towers. The turbine is pitch-controlled, variable speed, and can be equipped with an arctic package
enabling continuous operation at temperatures down to -40° C. A variant of this turbine is the EWT54-
900 which is identical to the EWT52-900 but equipped with a 54 meter diameter rotor and limited to IEC
Class III sites. The wind resource analysis of the Pitka’s Point met tower indicated sufficiently strong
wind gust potential to classify the site as IEC Class II by extreme wind probability (see earlier discussion
in this report).
Three EWT-900 wind turbines are presently operational in Alaska, one in Delta Junction and two in
Kotzebue. The EWT52-900 wind turbine is manufactured in Amersfoort, The Netherlands, with North
American representation in Bloomington, Minnesota. More information can be found at
http://www.ewtinternational.com/?id=4 . The turbine power curve is shown below.

Load Demand
This analysis includes stand-alone electric and thermal load demand in St. Mary’s (which includes
Andreafsky and Pitka’s Point) and the combined electric load demand of St. Mary’s and nearby Pilot
Station once the proposed electrical intertie is complete.
St. Mary’s Electric Load
Saint Mary’s/Andreafsky load data, collected from December 26, 2009 to October 27, 2011, was
received from Mr. Bill Thompson of AVEC. These data are in 15 minute increments and represent total
electric load demand during each time step. The data were processed by adjusting the date/time
stamps nine hours from GMT to Yukon/Alaska time, multiplying each value by four to translate kWh to
kW (similar to processing of the wind turbine data), and creating a January 1 to December 31 hourly list
for export to HOMER software. The resulting load is shown graphically below. Average load is 354 kW
with a 621 kW peak load and an average daily load demand of 8,496 kWh.
Saint Mary’s, Alaska Wind Power Conceptual Design Analysis Page | 10
St. Mary’s electric load
Combined Saint Mary’s-Pilot Station Electric Load
Pilot Station is not equipped with automated logging equipment to document the electric load. But,
with plant operator logs, AVEC tracks the electric load which is documented in AVEC’s annual generation
report and also in the power cost equalization reports that AVEC submits to Regulatory Commission of
Alaska. It is assumed that the Pilot Station electrical load is similar to that of St. Mary’s load on a daily
and monthly basis. Hence, the measured St. Mary’s load was scaled to a daily load demand of 13,726
kWh to represent a combine St. Mary’s-Pilot Station electrical system when the intertie is complete.
St. Mary’s-Pilot Station combined electric load
Saint Mary’s, Alaska Wind Power Conceptual Design Analysis Page | 11
Thermal Load
The thermal load demand in St. Mary’s is well quantified and described in a report entitled St. Mary’s,
Alaska Heat Recovery Study, prepared for the Alaska Energy Authority by Alaska Energy and Engineering,
Inc. and dated August 31, 2011. This report is quite comprehensive and won’t be summarized here.
Thermal load data needed for HOMER modeling was extracted from a heat demand/heat available
graph on page 5 of the report. Monthly thermal heat demand is graphed as a heating fuel equivalent in
gallons per month, which was converted to kW demand with a conversion of 0.0312 gallons heating fuel
per kWh. Although not entirely precise, the monthly heat demand was equalized across the entire day
for each month and then randomized a bit with a five percent day-to-day and five percent time step-to-
time step random variability. Resulting thermal load is show below.
Saint Mary’s thermal load
Diesel Generators
The HOMER model was constructed with all three St. Mary’s generators. For cost modeling purposes,
AEA assumes a generator O&M cost of $0.020/kWh. For HOMER modeling purposes, this was converted
to $2.50/operating hour for each diesel generator. Other diesel generator information pertinent to the
HOMER model is shown in the table below. Note that the Saint Mary’s power plant operates is
equipped with automated switchgear and can operate in automatic mode with generators in parallel.

WAsP Modeling, Wind Turbine Layout
WAsP (Wind Atlas Analysis and Application Program) and is PC-based software for predicting wind
climates, wind resources and power production from wind turbines and wind farms and was used to
model the Pitka’s Point terrain and wind turbine performance.
WAsP software calculates gross and net annual energy production (AEP) for turbines contained within
wind farms, such as an array of two or more turbines in proximity to each other. For s single turbine
array, WAsP calculates gross AEP. With one turbine, net AEP is identical to gross AEP as there is no wake
loss to consider.
Orographic Modeling
WAsP modeling begins with import of a digital elevation map (DEM) of the subject site and surrounding
area and conversion of coordinates to Universal Transverse Mercator (UTM). UTM is a geographic
coordinate system that uses a two-dimensional Cartesian coordinate system to identify locations on the
surface of Earth. UTM coordinates reference the meridian of its particular zone (60 longitudinal zones
are further subdivided by 20 latitude bands) for the easting coordinate and distance from the equator
for the northing coordinate. Units are meters. Elevations of the DEMs are converted to meters if
necessary for import into WAsP software.
A met tower reference point is added to the digital elevation map, wind turbine locations identified, and
a wind turbine(s) selected to perform the calculations. WAsP considers the orographic (terrain) effects
on the wind (plus surface roughness and obstacles) and calculates how wind flow increases or decreases
at each node of the DEM grid. The mathematical model has a number of limitations, including the
assumption of overall wind regime of the turbine site is the same as the met tower reference site,
prevailing weather conditions are stable over time, and the surrounding terrain at both sites is
Saint Mary’s, Alaska Wind Power Conceptual Design Analysis Page | 13
sufficiently gentle and smooth to ensure laminar, attached wind flow. WAsP software is not capable of
modeling turbulent wind flow resulting from sharp terrain features such as mountain ridges, canyons,
shear bluffs, etc.
Orographic modeling of the wind across the site, with the Pitka’s Point met tower as the reference site,
indicates an outstanding wind resource on the top edge of the bluff, especially downhill from the met
tower toward the Yukon River and the village of Pitka’s Point.

Wind Turbine Project Site
The project site is Pitka’s Point Native Corporation land on and near the location of the Pitka’s Point met
tower, with boundaries of the Pitka’s Point/Saint Mary’s Airport road to the north, a rock quarry to the
east, the bluff to the south, and a Native Allotment to the west. More specifically, AVEC has obtained
site control on Lot 6 within these general boundaries for turbine siting. Site control of Lot 6 is adequate
to site one EWT52-900 turbine, but lease rights to additional Pitka’s Point Native Corporation property
on the bluff edge would be necessary for an ideal layout of Northern Power 100 turbines.
It is important to note that winds at the project site, though very robust as a Class 6 wind resource, are
prone to rime icing conditions in winter. Rime icing is more problematic for wind turbine operations
than freezing rain (clear ice) given its tenacity and longevity in certain climatic conditions. Anti-icing
and/or de-icing features may be necessary to sustain availability during the winter months.
Northern Power 100 ARCTIC Turbine Layout
The Northern Power turbines are located on the bluff edge, which is on and near Lot 6 on Pitka’s Point
Native Corporation land. Using WAsP software, turbine locations were selected that have high gross
energy production based on predicted site wind speeds, but at the same time result in minimal array
loss, thus yielding a high net energy production.

WAsP Modeling Results for Northern Power 100 ARCTIC Array
The following table presents the WAsP software analysis of energy production and capacity factor
performance of the Northern Power 100 in a three turbine array at 100% turbine availability (percent of
time that the turbine is on-line and available for energy production). The Northern Power 100 performs
very well in the Pitka’s Point wind regime with excellent annual energy production and minimal array
wake loss.
Note that the standard (atmospheric conditions) power curve was compensated to the measured mean
annual site air density of 1.273 kg/m3. For the stall-controlled Northern Power 100, power output (for
each m/s wind speed step) of the standard power curve was multiplied by the ratio of site air density to
standard air density of 1.225 kg kg/m3 and capped at a maximum 100 kW output.

EWT52-900 Turbine Layout
Although orographic modeling indicates highest wind resource on the bluff edge downhill from the met
tower, toward the Yukon River and the village of Pitka’s Point, land use restrictions dictated placement
of the turbine in the southeast corner of Lot 6. This location, though, should still be considered highly
desirable for wind energy production by any standard.

The following table presents the WAsP software analysis of energy production for the EWT 52-900 wind
turbine at 100% turbine availability (percent of time that the turbine is on-line and available for energy

with excellent capacity factors and annual energy productions.
Note that the standard (atmospheric conditions) power curve was compensated to the measured mean
annual site air density of 1.273 kg/m3. For the pitch-controlled EWT 52-, power output (for each m/s

Economic Analysis
Homer software was used to model static energy balance of the Saint Mary’s electrical and thermal
power system at one hour increments of time. For both wind turbines considered, they are modeled as
connected to the electrical distribution system with first priority to serve the electrical load and second
priority to serve the thermal load via a secondary load controller and electric boiler.
Wind Turbine Costs
Capital and installation costs of three Northern Power 100 ARCTIC wind turbines to serve the village of
St. Mary’s are based on AVEC’s cost estimate in their Renewable Energy Fund Round V proposal. Total
proposed project cost, including distribution system extension and AVEC cost share, is $4,443,244,
based on a cost estimate developed in 2011 for a Renewable Energy Fund Round 5 analysis.
An alternative consideration, which would serve only the village of St. Mary’s initially but later would
also serve the village of Pilot Station once the intertie is complete, is installation of one EWT52-900 wind
turbine on a 50 meter tower. Total project cost for the EWT52-900 turbine, including distribution
system extension and power plant upgrades, is $6,153,991.
St. Mary’s to Pilot Station Intertie Cost
An economic analysis of the EWT 52-900 wind turbine in a combined Saint Mary’s/Pilot Station electrical
system must include the cost of connection as the intertie does not presently exist. This cost, though, is
more than simply the cost to build the intertie. It includes avoided costs such as a power plant and bulk
fuel upgrade in Pilot Station that will not be built if an intertie to Saint Mary’s is constructed instead.
Interestingly, this also includes the opportunity of wind power. Airspace restrictions around Pilot
Station preclude the option of wind turbines for the village, but with an intertie, the wind power project
plan for St. Mary’s will be available to also serve Pilot Station.
A preliminary cost analysis of non-intertie vs. intertie scenarios is presented in the table below.
Although the intertie itself is projected to cost $5.95 million, the net cost of the intertie, with avoided
capital costs considered, is a very modest $260,000.

Beyond the avoided capital costs, the benefits of an electrical intertie between Saint Mary’s and Pilot
Station include increased efficiency of the diesel generators in Saint Mary’s as they will operate at higher
loading levels and hence more efficient points of their fuel curves, reduced operating and maintenance
expenses with fewer diesel generators on line, lower labor costs, reduced maintenance expenses, and
reduced repair and emergency expenses with operations consolidated in Saint Mary’s. A separate
economic analysis indicates a benefit-to-cost ratio of approximately 1.20 for 20 to 50 year evaluation
periods.
Fuel Cost
A fuel price of $5.02/gallon ($1.33/Liter) was chosen for the initial HOMER analysis by reference to
Alaska Fuel Price Projections 2012-2035, prepared for Alaska Energy Authority by the Institute for Social
and Economic Research (ISER), dated July, 2012. The $5.02/gallon price reflects the average value of all
fuel prices between the 2014 (assumed project start year) fuel price of $4.53/gallon and the 2033 (20
year project end year) fuel price of $5.48/gallon using the medium price projection analysis with social
cost of carbon (SCC) included (see ISER spreadsheet for Renewable Energy Fund Round 6 analysis).
By comparison, the fuel price for Stebbins (without social cost of carbon) reported to Regulatory
Commission of Alaska for the 2011 PCE report is $2.71/gallon ($0.716/Liter).

Modeling Assumptions
HOMER energy modeling software was used to analyze the Saint Mary’s power System. HOMER is a
static energy model designed to analyze hybrid power systems that contain a mix of conventional and
renewable energy sources, such as diesel generators, wind turbines, solar panels, batteries, etc. Homer
software is widely used in the State of Alaska to aid development of village wind-diesel power projects.
HOMER modeling assumptions are detailed in the table below. Many assumptions, such as project life,
discount rate, operations and maintenance (O&M) costs, etc. are AEA default values. Other
assumptions, such as diesel overhaul cost and time between overhaul are based on general rural Alaska
power generation experience.
The base or comparison scenario is the existing St. Mary’s/Andreafsky powerplant with its present
configuration of diesel generators. Also assumed in the base or comparison scenario is that excess
powerplant heat serves the thermal load via a heat recovery loop.
Wind turbines constructed at the Pitka’s Point site are assumed to operate in parallel with the diesel
generators. Excess energy will serve thermal loads via a secondary load controller and electric boiler.
Installation cost of either three NW100 wind turbines or one EWT-500 wind turbine assumes a three-
phase distribution line extension from the road to the wind turbine site plus a two-phase to three-phase

Project Cost Assumptions
Three basic project configuration and benefit-to-cost evaluations are considered with Homer modeling,
as listed below.
Configuration Number:
1. Three Northern Power 100 wind turbines serving only the Saint Mary’s electrical and thermal
load; total project cost of $4,443,244.
Saint Mary’s, Alaska Wind Power Conceptual Design Analysis Page | 21
2. One EWT 52-900 wind turbine serving only the Saint Mary’s electrical and thermal load; total
project cost of $6,153,991.
3. One EWT 52-900 wind turbine serving an intertied Saint Mary’s and Pilot Station electrical load
and Saint Mary’s thermal load; total project cost of $6,413,991. This cost estimate reflects the
cost of installing one EWT 52-900 turbine in St. Mary’s plus the cost the St. Mary’s to Pilot
Station intertie less the avoided capital costs when closing the Pilot Station powerhouse and
consolidating generation operations to Saint Mary’s (see below).

The GRANTOR, ST. MARY’S NATIVE CORPORATION, (herein called the GRANTOR),
whose address is P.O. Box 149, St. Mary’s, Alaska, 99658, for good and valuable consideration,
receipt of which is hereby acknowledged, does hereby grant to ALASKA VILLAGE ELECTRIC
COOPERATIVE, INC., an Alaskan non-profit electric cooperative membership corporation,
whose address is 4831 Eagle Street, Anchorage, Alaska 99503, hereinafter called the
GRANTEE, an easement and right-of-way in perpetuity for the purposes of constructing,
reconstructing, maintaining, repairing, operating, improving, upgrading and updating above,
beneath and on the surface of the below-described lands, electric transmission, distribution,
and/or communication lines(s) and/or systems, including poles, towers, conductors, transformers,
pads, pedestals and associated apparatus, and such other structures as the GRANTEE may now
or shall from time to time deem necessary, in the following described parcel(s) of land situated in
the Bethel Recording District, Fourth Judicial District, State of Alaska, along, under, through and
across the entire parcel described as follows:
Seward Meridian, Township 23 North, Range 76 West, Sections 1, 11, 12, 13, 14, 23,
24, 25, 26, 35 and 36.
After construction and survey by GRANTEE, the easement will be fifty (50) feet on each side of
the centerline of the facilities described above. GRANTEE shall provide a copy of the survey to
GRANTOR, and GRANTEE will record a Record of Survey. Upon recording of the Record of
Survey, the extent of this easement shall be reduced to the dimensions shown on the Record of
Survey.
GRANTEE’s rights shall include the right:
1. of ingress and egress to said lands as may be reasonably necessary for the
purposes described above;
2. to cut, trim, excavate, remove, and control the growth of trees, shrubs, and other
vegetation on, above, or adjoining said lands which, in the sole, good faith
judgment of Grantee, might interfere with the proper functioning and maintenance
of said line or system; and
3. to license, permit or otherwise agree to the exercise of these rights by any other
authorized person or entity for electrical or communications purposes.

Reserving unto the GRANTOR the right to use said property in any way and for any purpose not
inconsistent with the rights hereby acquired; provided that GRANTEE shall have the right, as
may be necessary, to enter upon said property for the purposes herein described, and provided
that no building or buildings or other permanent structures shall be constructed or permitted to
remain within the boundaries of said easement without written permission of GRANTEE, its
successors or assigns.
GRANTOR agrees that all facilities, including any main service entrance equipment, installed on
the above described lands at the GRANTEE’s expense shall remain the property of the
GRANTEE, removable at the option of the GRANTEE, upon termination of service to or on said
lands. This easement shall be a covenant running with the land and shall be binding on the
GRANTOR, heirs, executors, administrators and assigns forever. If the GRANTOR requires
lands within this zone easement in the future, this easement may be amended contingent on
agreement between the GRANTEE and GRANTOR.
If the intertie is not constructed within 15 years from the date of this grant, the zone easement
will automatically terminate.
