SECTION 2 – PROJECT SUMMARY
Provide a brief 1-2 page overview of your project.
2.1 PROJECT TYPE
Describe the type of project you are proposing, (Reconnaissance; Resource Assessment/ Feasibility
Analysis/Conceptual Design; Final Design and Permitting; and/or Construction) as well as the
kind of renewable energy you intend to use. Refer to Section 1.5 of RFA.
We propose a project to complete the Final Design & Permitting and Construction of a system to
add electrical generation from wind power to the existing electrical generation and distribution
system.
2.2 PROJECT DESCRIPTION
Provide a one paragraph description of your project. At a minimum include the project location,
communities to be served, and who will be involved in the grant project.
Our project involves the final design, permitting, construction, erection, startup, and
commissioning of one additional wind turbine to supplement the existing power generation and
distribution system for the community of Toksook Bay. Participants in the project include AVEC,
STG, and Northern Power. AVEC will provide overall project management and electrical system
engineering for the project. STG will be the general contractor, responsible for the design and
installation of all civil works, erection of the wind turbine, and installation of all ancillary electrical
systems. Northern Power will provide the Northwind 100 wind turbine and startup &
commissioning services. The site is already under control and already contains three Northwind
100 wind turbines. Existing permits are in place and can be extended to cover the additional
wind turbine.
2.3 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. Include a project cost summary that includes an
estimated total cost through construction.
The project requires $1,153,056 to complete. Design & Permitting will require $31,500.
Construction will require $1,105,806. Commissioning will require $15,750. AVEC will provide
10% of the total amount as a cash contribution, totaling $115,306.
2.4 PROJECT BENEFIT
Briefly discuss the financial benefits that will result from this project, including an estimate of
economic benefits(such as reduced fuel costs) and a description of other benefits to the Alaskan
public.
The primary financial benefit from this project will be reduced fuel costs to the people of
Toksook Bay. Simulations of wind resource versus load demand result in an estimated gross
fuel savings of over 12,600 gallons of diesel fuel per year beyond the benefits of the existing
three wind turbines. Global Energy Concepts conducted an independent study of wind turbine
availability for AVEC. That study concluded that gross production estimates of energy
production from wind turbines should be reduced by 18% to account for downtime. AVEC has
anecdotal evidence to indicate that downtime is decreasing with experience and is currently
somewhat less than that figure at existing Northwind 100 sites.
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 3 of 11 9/3/2008
Nevertheless, for the purposes of this grant application, we will reduce expected fuel savings for
electricity production by 18%, that being the most recent independently estimated figure
available. Reducing the gross estimate by 18%, we expect to save over 11,000 gallons of diesel
fuel per year at Toksook Bay, beyond the savings of the three existing wind turbines. At AVEC’s
2008 actual average price of fuel at Toksook Bay of $4.6278/gallon, savings will exceed
$51,000 per year. If the price of fuel rises to $5.50/gallon, the savings will exceed $60,000 per
year. If downtime can be cut in half, reduced to 9% from the 18% we are carrying for this
application, then annual savings will approach $55,000 at current diesel prices and $65,000 at
$5.50/gallon.
In addition to the direct fuel reduction are the benefits of:
- reduced long-term dependence on outside sources of energy;
- reduced exposure to fuel price volatility;
- reduced air pollution resulting from reducing fossil fuel combustion;
- reduced possibility of spills from fuel transport & storage; and
- reduced overall carbon footprint and its contribution to climate change.
2.5 PROJECT COST AND BENEFIT SUMARY

SECTION 3 – PROJECT MANAGEMENT PLAN
Describe who will be responsible for managing the project and provide a plan for successfully
completing the project within the scope, schedule and budget proposed in the application.
3.1 Project Manager
Tell us who will be managing the project for the Grantee and include a resume and references for
the manager(s). If the applicant does not have a project manager indicate how you intend to solicit
project management Support. If the applicant expects project management assistance from AEA or
another government entity, state that in this section.
Alaska Village Electric Cooperative’s (AVEC) project management approach to this project, and
to its overall energy upgrade program, is to utilize a team approach consisting of AVEC staff,
external consultants and construction management contractors.
AVEC provides a project team from its operating staff. The President and CEO acts as Program
Executive and maintains ultimate authority programmatically and financially. The manager of the
community development group acts as program manager. The group provides internal focus
and coordination of special projects including project development, planning, construction
coordination, and reporting. Resources include a project coordinator, contracts clerk,
accountant, engineer, and community liaison. The vice president and manager of AVEC’s
engineering group provide technical input on generation and distribution issues to the team.
Additionally, the engineering group provides specifications, design and drawings for AVEC
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 4 of 11 9/3/2008
construction of diesel power plants and distribution systems. The manager of operation and
construction provides construction management and commissioning input on behalf of new
construction performed by AVEC staff. The manager of administrative services provides support
in accounting, payables, financial reporting, and capitalization of assets in accordance with RUS
guidelines.
The project management team’s structure is designed to provide flexibility for the AVEC
participants. They have operational responsibilities to the Cooperative as well as project
development responsibilities. The functional-interface relationships allow engineering tasks,
village government and public relations tasks, procurement functions, and internal construction
operations to be dovetailed into the project development process. Cross utilization of talent and
resources is an advantage to the project delivery process, providing economies of scale for
utilization of project resources.
For project delivery, an amalgamated team approach is utilized. To support the AVEC team,
design consultants and construction managers (CM) are selected. Both disciplines are derived
from a resource bank of professional firms with applicable histories of performance in rural
Alaska. The construction manager works 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 are
formulated by the CM in collaboration with AVEC’s purchasing manager. Each package is
competitively procured or issued from cooperative materials. Purchase orders are formulated
with delivery dates consistent with dates required for barge or air transport consolidation.
Multiple materials and/or equipment are detailed for consolidated shipments to rural staging
points, where secondary transport to the village destination is provided. The CM tracks the
shipments and provides handling services to and around the destination project sites.
The CM is responsible for the construction activities for all project components of the facility
upgrade. Local labor forces are utilized to the maximum extent possible to construct the
projects. Local job training is provided as a concurrent operation under the management and
direction of the CM. All construction costs, direct and indirect are 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.
AVEC’s concern and objective is to have a managed project delivery approach from inception
through operation.

3.4 Project Resources
Describe the personnel, contractors, equipment, and services you will use to accomplish the project.
Include any partnerships or commitments with other entities you have or anticipate will be needed to
complete your project. Describe any existing contracts and the selection process you may use for
major equipment purchases or contracts. Include brief resumes and references for known, key
personnel, contractors, and suppliers as an attachment to your application.
AVEC will ultimately be responsible for successful completion of the project, using the same
partners that successfully installed the existing wind turbines at Toksook Bay. Electrical system
engineering will is minimal and will be subcontracted, using current internal procurement
practices and selection of engineering service providers from prequalified organizations. STG
will provide the wind turbine foundations on a design/build basis, as they did previously at this
site. STG will also provide all ancillary electrical equipment and install the wind turbines and the
electrical balance of plant.
A 100kW Northwind 100 wind turbine from Northern Power will be used. The permanent
magnet, direct drive Northwind 100 is the latest wind turbine model from Northern Power, based
on earlier NW100 wind turbine models that AVEC has installed and operated in wind/diesel
applications for several years now. Developed in conjunction with NASA, NREL, and NSF
specifically for remote use in extreme environments, the Northwind 100 embodies the most
recent design practices in the industry. Northern Power’s experience with wind/diesel control
systems complements AVEC’s.
3.5 Project Communications
Discuss how you plan to monitor the project and keep the Authority informed of the status.
AVEC will assign a project manager to the project. One responsibility of the project manager will
be to compile periodic progress reports for use by the Authority. Weekly and monthly project
coordination meetings will be held with the project team to track progress and address issues as
they arise.
3.6 Project Risk
Discuss potential problems and how you would address them.
In general, logistics, construction activities and weather all contain siginficant risks. AVEC
routinely purchases Builder’s Risk insurance to mitigate its exposure to these risks. In addition
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 6 of 11 9/3/2008
to outside insurance, the experienced team of AVEC and STG has already installed three
Northwind 100 wind turbines at this site.
Logistics is a routine issue in rural Alaska. AVEC and STG both have extensive experience with
the logisitcal conditions found in this Alaskan village. Advance planning and allowing time for
contingencies is crucial to success in such environments.
Construction can be challenging in rural Alaska. Both AVEC and STG routinely conduct
construction operations in villages much like this one.
Weather is another challenge when working in rural Alaska. AVEC and STG have worked in this
area for years. As with logistics, allowing time for contingencies is important.
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 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 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.
Toksook Bay is a high-value, class 6 wind regime for wind power generation. During 2007,
1,916,175 kWh of energy was generated at the Toksook Bay power plant using 137,459 gallons
of diesel fuel. Three NW100 wind turbines produced an additional 624,194 kWh for a total
production at the site of 2,540,369 kWh. One additional NW100 wind turbine generating an
additional 270,000 kWh per year could displace an additional 8% of the energy normally
generated by diesel, and provide excess energy to heat water.
The village of Toksook Bay is blessed with abundant winds but finds its fuel supply limited and
costly. Solar power from photovoltaic solar arrays is a potential alternative, but suffers from
higher capital cost and lower resource availability than wind at this site.
Production of energy using tidal motion in the sea is a newly developing possibility. Technology
to make use of tidal motion is as yet immature. Even after initial development activities have
been completed, the sub-arctic maritime environment of much of Alaska will provide additional
challenges to the use of this developing technology.
4.2 Existing Energy System
4.2.1 Basic configuration of Existing Energy System
Briefly discuss the basic configuration of the existing energy system. Include information about the
number, size, age, efficiency, and type of generation.
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 7 of 11 9/3/2008
The existing power plant at Toksook Bay consists of three separate diesel-powered engine
generator sets, of 363 kW, 499 kW, and 756 kW capacity. These gensets were originally
installed and started up in 2005. They have not yet been overhauled. Three NW100 wind
turbines, each rated at 100 kW, were installed in 2006. The diesel plant generated 13.94 kWh for
each gallon of fuel consumed in 2007. The wind turbines generated a total of 624,194 kWh in
2007.
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.
The existing power plant produces electrical energy by burning diesel fuel in engine-driven
generators and by using the wind to drive turbines. By adding an additional wind turbine to the
existing system, we expect the project to reduce the amount of diesel fuel used today at the site.
In addition to offsetting diesel-generated electricity, we also expect to use whatever wind-
generated energy that exceeds electrical demand to heat water, also displacing diesel fuel that is
presently burned in boilers.
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
Toksook Bay is one of three villages located on Nelson Island, on Kangirlvar Bay, across the
water from Nunivak Island. It is subject to subfreezing temperatures, extended periods of
darkness and blowing snow. Reliable electric service is essential to maintaining home heating
systems necessary to safeguard the health of the population, especially the elderly and infants.
Toksook Bay relies to a great degree on air transportation for delivery of medical goods and
transport of sick or injured individuals or mothers nearing childbirth. Reliable electric service is
essential to maintaining vital navigation aides for the safe operation of aircraft. Runway lights,
automated weather observation stations, VASI lights, DME’s and VOR’s are all powered by
electricity.
Emergency medical service is provided in Toksook Bay 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.
Water in Toksook Bay comes from a well and is piped throughout the village. 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.
Toksook Bay is subject to long periods of darkness. Reliable electric service is essential for the
operation of home lighting, streetlights and security lighting. Children walk to school and outside
lighting helps them find their way and be on the look out for hazards such as deep snow or in the
extreme case, polar bears.
Subsistence activities provide essential food sources to most residents of Toksook Bay. Food is
gathered and harvested and then stored for when it is needed. Refrigeration is essential for the
extended storage of perishable food stuffs. Reliable electric service is essential for proper freeze
storage of food.

AEA 09-004 Grant Application Page 8 of 11 9/3/2008
We expect the addition of an additional wind turbine to the electric generation system to further
reduce the amount of diesel fuel used on the island for power generation and for heating.
4.3 Proposed System
Include information necessary to describe the system you are intending to develop and address
potential system design, land ownership, permits, and environmental issues.
4.3.1 System Design
Provide the following information for the proposed renewable energy system:
• A description of renewable energy technology specific to project location
• Optimum installed capacity
• Anticipated capacity factor
• Anticipated annual generation
• Anticipated barriers
• Basic integration concept
• Delivery methods
Renewable Energy Technology Description
The system we plan includes one new 100kW NW100 wind turbine.
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.
We expect one additional NW100 wind turbine to produce over 10% of the electricity consumed
on the island today. This additional wind turbine should supply almost 270,000 kWh of electrical
energy annually, including 125,000 kWh for use to heat water.
Anticipated Barriers
Logistical and weather barriers are common in the area. AVEC has routinely overcome these
barriers in similar projects in similar areas. Permitting can sometimes affect projects adversely.
At Toksook Bay, the permits for the existing wind turbine facility can be extended to cover the
addition of one more turbine.
Basic Integration Concept
The new wind turbine will interconnect with the existing turbines and diesel power plant.
Renewable Energy Fund

AEA 09-004 Grant Application Page 9 of 11 9/3/2008
Delivery Methods
The wind-generated electrical energy will be delivered using the existing electrical distribution
grid.
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 control of the land required for the installation of the wind turbines and for their
connection to the existing power plant.
4.3.3 Permits
Provide the following informationas 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

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
All environmental issues have been addressed for the existing site.
4.4 Proposed New System Costs (Total Estimated Costs and proposed Revenues)

• Identification of other funding sources
• Projected capital cost of proposed renewable energy system
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 10 of 11 9/3/2008
• Projected development cost of proposed renewable energy system
This application is for the last phase of the project. Preliminary work has already been done. We
anticipate that the project will cost $1,153,056 to complete from this point. We are requesting
$1,037,750 from AEA. AVEC will provide $115,306 as a cash contribution toward the project.
Source of Cost Data
Anticipated costs for wind equipment are per manufacturer’s estimates; all other cost estimates
are derived from recent experience of Applicant and its consultants and construction managers,
based on similar projects recently constructed or now under construction.
4.4.2 Project Operating and Maintenance Costs
Include anticipated O&M costs for new facilities constructed and how these would be funded by the
applicant.
• Total anticipated project cost for this phase
• Requested grant funding
AVEC’s existing NW100 wind turbines require two maintenance visits a year. Those visits
currently cost AVEC $3,500 per turbine per year. The new NW100 model at Toksook Bay will
require an annual maintenance cost of $3,500. This cost will be funded by ongoing energy sales
in the village.
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
The project breaks even between 15 and 16 years.
4.4.4 Cost Worksheet
Complete the cost worksheet form which provides summary information that will be considered in
evaluating the project.
Download the form, complete it, and submit it as an attachment. Document any conditions or sources
your numbers are based on here.
See the attachment.
4.4.5 Business Plan
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.
The project will be incorporated into AVEC’s power plant operation. Maintenance will be
managed in the same way as the maintenance of the diesel plant is managed.
4.4.6 Analysis and Recommendations
Provide information about the economic analysis and the proposed project. Discuss your recommendation
for additional project development work.
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 11 of 11 9/3/2008
The wind turbines and control systems provided as part of this project will be fully incorporated
into AVEC’s power plant operations. From that perspective, the wind turbines will be treated as
generating equipment, just like the generator sets. Maintenance schedules will be routinely
developed and managed. The result will be improved reliability from the existence of additional
generating sources and reduced fuel consumption from the use of wind. We do not anticipate
any additional project development work at this site following this project.
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 avoided cost of ownership)
• 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
We expect one additional NW100 wind turbine to displace over 11,000 gallons of diesel fuel
each year. So far in 2008, AVEC has spent an average of $4.6287 per gallon for the fuel it has
used to generate electricity at Toksook Bay. If that continues to be rate through the first year of
operation of the wind turbines, then the additional turbine will save over $50,000 during that first
year. Assuming a 4% rate of inflation for the next 20 years, we expect the addition of this single
turbine to save over $1.6 million over that period of time. At this rate, the project breaks even at
between 15 and 16 years.
The non-economic benefits to the Alaskan population at large will be from the reduced carbon
footprint of the power plant. By reducing the amount of fuel burned at the site by an additional
10%, we will prevent over 100 tons of carbon dioxide from entering the atmosphere each year.
SECTION 6 – GRANT BUDGET
Tell us how much your total project costs. Include any investments to date and funding sources, how
much is requested in grant funds, and additional investments you will make as an applicant.
Include an estimate of budget costs by tasks using the form - GrantBudget.xls.
Provide a narrative summary regarding funding sources and your financial commitment to the project.
AVEC is committed to providing $115,306 toward the completion of this project.
