2.4 PROJECT DESCRIPTION
Provide a brief one paragraph description of your proposed project.
The proposed project is a medium to high penetration for the community of Kipnuk, Alaska.
The project will be owned and operated by the Kipnuk Light Plant and the community of
Kipnuk, and consists of three Northwind 100 wind turbines, a modular hybrid wind diesel power
conditioning control module, a 200 kW frequency controlled heat recovery boiler, 20 residential
electric thermal storage devices. This hybrid power system is designed to fit with the existing
diesel powerplant, and wrap into any new plant proposed for the future. The wind turbines are
well proven in Alaska, the power conditioning and controls module is able to be located next to
the existing or new powerplant. The power control and conditioning module will contain new
wind diesel controls and switchgear, grid regulating inverter and energy storage unit for grid
stabilization. The 20 electric thermal storage devices will capture any excess available wind
energy and store it as heat for residential heating. The wind turbines and hybrid controls and
power conditioning module will be mounted on pile foundations, on property provided by the
community.
This wind diesel system architecture is scalable through the addition of wind turbines, new diesel

gensets, addition of more real energy storage in the form of batteries, flywheel or capacitors. The
system is also capable of accomodating addition of residential electric thermal storage devices
when additional wind energy capacity becomes available.
2.5 PROJECT BENEFIT
Briefly discuss the financial and public benefits that will result from this project, (such as reduced fuel
costs, lower energy costs, etc.)
The benefits of the this project include:
The wind energy will displace 42,890 gallons of fuel used to generate electricity and 12,300
gallons of heating fuel. The annually savings to the utility that can be passed onto the customers
total $275,950 annually based on a $5.00/gallon (AEA conceptual design report) average price
for fuel over the life of the project.
The electric thermal storage devices have the potential to reduce residential heating costs in the
20 homes by 50%. This represents a displacement of residential heating fuel equivalent to
$52000 annually.
Additional turbines and off peak stoves can increase the benefit in the future.
The annual heating costs based on $8.00/gallon home heating fuel price. The savings will be
realized through the sale of an equivalent amount of excess electricity at 50% of the displaced
fuel cost. This shares the savings equally between the customer and the utility, which will
charge $.15 to $.20/KWhr for surplus wind energy.
Beyond a reduction in fuel use, cheaper power and lower heating costs, additional benefits of the
project include:
- Increased local employment and training
- Reduced reliance on the volatility of fuel prices
- Reduced risk of fuel spills
- Reduced local air pollution and contribution to climate change
- Increased revenue to the utility company
- Reduced PCE payments
- Use of the smart grid to improve management of utility and improve efficiency of the utility

3.5 Project Communications
Discuss how you plan to monitor the project and keep the Authority informed of the status.
A full-time, qualified project manager will be monitoring this project. The project point of
contact and the project manager will jointly submit periodic status reports. Additionally, 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.
There are inherent risks in any project involving construction, logistics, and unpredictable
weather. One primary advantage this project has is that Kipnuk is a member of the
ChaninikWind Group, which has created a strong and supportive assistance network in the
region. This includes expanded access to tools, equipment training, spare parts, and
transportation and service options. The team of Intelligent Energy Systems and STG has
experience managing the logistics of this project.
Many questions involved in the installation of wind turbine in villages have been answered, and
problems solved. The primary is increasing the cost effectiveness of the projects, and
simplifying operations and reducing maintenance. This project has elected to use the Northwind
100. This is one of the most expensive wind systems available, however the performance of the
turbines is well understood.
The project integration is built around a fully tested, power control and conditioning module,
which include switchgear, hybrid system controls, a power conditioning inverter and 250 kWhrs
of lithium ion battery energy storage. Similar power conditioning and energy storage modules
are being installed in utility applications in the U.S. and Europe. There are two primary reasons
for this, cost and performance. Several different types of power conditioning modules are
available in the market place, from large and very reputable supplies such as ABB, GE, S&C
Electric, American Superconductor and others. These offering are the result of major advances in
power electronics manufacturing, which has resulted in 50% cost reduction over the last 3 years.
These systems are being manufactured in serial production for widespread application. It is
anticipated that smaller footprint STATcom/DVR devices will become increasing common
through all electrical grids. The manufacture and supply of lithium ion batteries are following the
same trend, of packaged modules, with higher performance and lower costs. This is largely due
to the recent expansion of manufacturing capacity to meet the plug in and hybrid vehicle
markets. It has been projected that the cost of high performance lithium ion battery banks will
decrease by a factor of 5 to 10 over the next 5 to 7 years, as automobile orders increase. These
large industrial electrical equipment suppliers are beginning to produce these types of grid
connected storage solutions, in modular and custom sizes, and are backing their installation will
full warranties, and testing programs which provide unprecedented levels of performance.

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.
Regional wind monitoring was placed in Kongiganak by the Alaska Energy Authority to collect
data representative for the region. Kipnuk is 30 miles away, and not a tree or hill in sight.) This
data was correlated with long term airport data by meteorologist, Ed McCarthy of WECTEC, and
J.P Pinard, P.E, PhD of Jp Pinard engineering to confirm the suitability of the resource. The
results of the wind resource evaluation indicate an outstanding wind resource with an average
wind speed of 7.78 m/s, and with the power distribution well suited for the capture of wind
energy.
The data was analyzed in the HOMER and Windographer software models to and compared with
the power curves of various candidate wind turbines. Only direct drive permanent magnet
generator wind turbines were evaluated, because of their record of long life and low maintenance.
The two primary wind turbines which are available in Alaska the Northwind 100 B model, the
EWT 900, 54 meter wind turbine. The HOMER modeling optimized the installation to 3,
Northwind 100. HOWEVER, the EWT has the ability to provide sufficient additional excess
wind capacity to displace 54000 gallons of home heating fuel and 66,000 gallons of diesel fuel
used for power generation, the cost of installation of the EWT with module and 100 electric
thermal storage devices to heat almost all of the homes in the community,, this would require a
budget of $6,000,000 which is beyond the limits of this program.
4.2 Existing Energy System
4.2.1 Basic configuration of Existing Energy System
Briefly discuss the basic configuration of the existing energy system. Include information about
the number, size, age, efficiency, and type of generation.
The existing power plant has a potential power generation capacity of 635 kW from three-diesel
generator with individual capacities of 250 kW, 250 kW, and 135 kW. The average community
load is 220 kW and peak load is 370 kW. The existing power generation facility has a heat
recovery system providing heat to the Kugkaktlik Limited, Traditional Council and Power Plant
Offices. The community has had to frequently ration power, and numerous times has had to
purchase fuel locally in small amounts at retail prices of up to $8.00 per gallon to continue to
generate power until the barge shipments arrive.
The new power plant and bulk fuel storage facility is proposed for construction in 2008-9, is
uncertain. The Wind Heat project could be constructed in conjunction with this project and fully
integrated into the system. The new power plant will have a generation capacity of 1,200 kW of
Renewable Energy Fund
Grant Application Round IV
AEA11-005 Grant Application Page 9 of 27 7/21/2010
diesel generation. The generators will be sized to meet the current power needs of the community
as projected for the next 10 years. Four generators with the following capacities of 370, 370, 230
and 230 kW are planned for installation in 2013. The generators will be integrated with an
automated control system, which can optimize the selection of gensets.
Investments were made in the installation of a new Cummins 350 kW genset was installed, and
the AEA is in the process of installing a new Cat 3456, electronically fuel injected generator rated
457 kW.
Population data for Kipnuk show a constant population growth since 1990. The current
population is 680. Data for the last 5 years showed a growth of 7% that has slowed to 1.5%
annually.
New facilities and new loads include:
AVCP 25 single family dwellings, in next 10 years.
ADOT, new airport facilities, 120 kW
ANTHC, clinic, 50 kW
Coastal Villages Regions Fund (CVRS) Fisheries Support Center potential fish plant.
A new school, is planned, 2013, 75 kW
Water and Sewer System, 2013, 75 kW
It has been estimated that the Electric Load will grow from its 2008, 1,657,658 kWhrs, to
2,381,000 kWhrs in by 2015. In the early years any excess wind energy will be captured and
stored to heat community buildings and residences.
Kipnuk has needed a new diesel powerplant for 10 years, and the Alaska Energy Authority has
proposed funding a new powerplant in Kipnuk for the last 7 years. It is unlikely that a new diesel
plant will receive funding for this project for several years. In the meantime the wind project,
which includes the power conditioning and control module, is intended to interface directly with
the old and newly proposed powerplant. Once installed the power conditioning and control
module will interface with the existing power plant and provide many benefits immediately.
These include: voltage and frequency regulation for improved powerquality, automation of diesel
powerplant operation, sufficient energy storage to ride through fault and peak lopping events of
up to 250 kW for 15 minutes. And of course, full integration of the wind in such a manner that the
diesels can be turned off approximately 1200 to 2000 hours per year. This will reduce diesel-
operating costs and result in immediate and long term savings to the utility.
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.
Fuel is delivered to Kipnuk via barge twice a year, once in the Spring and again in the Fall. Due
to limited bulk fuel storage capacity, Kipnuk Light Plant has nearly run out of fuel for the past
two years.
The viability of various sources of energy was assessed in the Kipnuk, Alaska Rural Power
System Upgrade Conceptual Design Report 2007. “The report on page 11 states: It is assumed
that upgrades to the community electrical power system incorporating supplemental wind energy,
Renewable Energy Fund
Grant Application Round IV
AEA11-005 Grant Application Page 10 of 27 7/21/2010
is a priority and will be conducted within the next ten years.”
This report was conducted when fuel prices were below $2.00 per gallon delivered in bulk to the
utility. Last year bulk fuel wholesale purchases were $4.26 per gallon. This translated to home
heating fuel costs of $8.00 per gallon.
Annual electrical load growth and step increases in demand were projected through 2017.
Demand grows from a peak of 339 kW now to a projected 709 kW.
The alternatives were narrowed to three;
Increased diesel efficiency: The current fuel efficiency of the diesel generation plant can be
increased from 10 kw/hr per gallon to 14 kWhrs per gallon. This would result in annual fuel
savings of 50,000 gallons per year.
Switching from #1 to #2 diesel fuel could save as much as 7,400 gallons per year.
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
Kipnuk is located on the west bank of the Kugkaktlik River in the Yukon-Kuskokwim Delta, 85
air miles southwest of Bethel. It lies four miles inland from the Bering Sea coast. The community
is located in a marine climate. Precipitation averages 22 inches, with 43 inches of snowfall
annually. Summer temperatures range from 41 to 57, winter temperatures are 6 to 24.
Kipnuk is accessible only by air or by snow machine in winter, and boat in summer, for delivery
of supplies.
In a recent RUBA report, it was indicated that Kipnuk meets all Essential indicators, and almost
all Sustainability indicators.
Kipnuk relies on electricity to maintain home lighting, street lighting, telephone service, school
service, clinic hours, and freezers to maintain a subsistence lifestyle. Reliable electricity is
crucial to the residents of Kipnuk.
Heat: A survey was conducted of heating fuel usage of each residence. These results are being
correlated with other records. This information indicates that on average, a typical residence in
Kipnuk uses 766 gallons of heating fuel annually, leaving an estimated 136,000 gallons of heating
fuel available for displacement with wind.
Heating fuel represents the single greatest cost of maintaining a residence. Typical costs last
year exceeded $ 6,000 per household. The availability of wind correlates well with heating
Renewable Energy Fund
Grant Application Round IV

needs. The ability to store this wind energy at night and when the loads are low, sell this wind
energy for half the cost of heating fuel, store the wind energy for use when needed, can reduce
average residential fuel costs by $3,000 annually per household.
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
High Penetration Wind Diesel Smart Grid
It has been demonstrated that low penetration systems, ones in which the proportion of wind to
diesel rarely exceed 30%, are not economical and construction costs are disproportionably high.
More importantly, the high cost of home heating is easily 3 to 5 times the cost of electricity in
rural Alaska, and soaring fuel costs are crippling communities. A primary object of this program
is to reduce dependency on diesel fuel and to reducing all energy costs in order to stabilize the
local economies.
The proposed system fulfils these objectives, more cost effective energy, by installation of a Phase
1, High Penetration Wind Diesel Smart Grid with Energy Storage, which will reduce fuel used to
generate electricity by 40%, while reducing residential heating costs in 20 homes by 50%. This
project will use wind to displace 57,190 gallons of heating fuel. Additionally these benefits are
returned to the utility in increased revenues and increased local employment. Additional benefits
are returned to the state in lower PCE contributions.
This proposed system provides an integrated village heat and power system which uses a smart
grid and thermal energy storage devices in each home to capture and store at a significantly
reduced cost, excess wind energy. The wind diesel system is stabilized through the use of power
conditioning module with 250 kW hours of energy storage in the form of standardized lithium ion
battery modules which are manufactured for the power generation industry and automobile
manufactures. The energy storage and power conditioning system will be used to balance
fluctuations in the load or wind turbine output.
This wind diesel architecture is designed to incorporate more wind, while reducing diesel
generation. The use of battery energy storage enables 2000 hours of diesel off operation and the
ability to accommodate other types of renewable generation including residential wind systems.
The power system is designed for expansion through the addition of increased numbers of wind
turbines, increased thermal storage devices and increased powerconditioning and energy storage
capacity. The metering and energy storage systems are a necessary component of the village
energy system management system and is responsible for the capture and beneficial use of the
Renewable Energy Fund
Grant Application Round IV

wind.
The system includes:
Three Northwind 100 wind turbines on 37 meter tubular towers. These turbines are being used
successfully across the state. The turbines towers will installed on pile foundations,
A containerized switchgear, control and integration module, containing switchgear, controls and a
lithium ion battery module.
Heat recovery will be through 200 kW of distributed thermal storage heaters will be placed in the
community building, head start preschool, the clinic, the homes of 20 village elders, and
through the installation of a 200 kW frequency controlled boiler in the power conditioning
module located in the community building. A smart metering system will enable the stoves on
and off as excess wind becomes available.
The three wind turbines with a rated output of 300 kilowatts.
Grid stability, as defined by voltage and frequency stability will be provide through the power
conditioning module and the action of fast acting load controllers on the heat recovery boiler and
residential electric thermal storage devices. The boiler and ETS units are configured to operate in
a complementary manner to the availability of excess wind. The power conditioning module with
battery storage regulates the voltage of the power system automatically decreasing diesel
generation and wind energy penetration is increased, to the point where the supervisory control
system signals the diesels to go off line. Primary responsibility for responding to frequency
changes occur at the boiler and ETS units.
The supervisory control system would monitor the electrical load demand and configures various
system operating modes. As the wind comes up, which occurs frequently at night most of the
winter, excess wind energy would be made available to customers at a reduced rate. . The
supervisory control system would determine the amount of available wind energy, while
optimizing power production and component output.
The supervisory controller would signal the metering system to enable various devices for
separate green energy sales and separately account for wind only and diesel only power sales.
Thermal Storage Devices in each home would be enabled to capture excess wind energy when
available and store it for heating use throughout the day or for several days. The ability of the
storage devices to store wind generated electricity
Below is a diagram of the proposed system. This diagram, contains three future elements, the
addition of more wind turbines, solar panels, and distributed residential energy storage. These
three components are shown only to indicate the extent of the system potential. The diagram
indicates the future implementation of plug in vehicles for local transportation.

The control and communications relationships of the power system components. The design
enables high wind penetration at all times, with the existing power system stabilized at low loads
with the flywheel to support any changes in power requirements or loss of wind output, while
decreasing diesel fuel usage.
The remote heat recovery boiler will be placed at the school, to absorb a limited amount of excess
wind energy, and the smart meter enabled thermal energy storage units in each of 20 residences
will capture the remaining wind. In low winds, the diesel power system will operate in a high
penetration mode, with the smallest genset on line or possibly turned off, and the available wind
captured to displace fuel used to generate electricity. As wind speeds increase greater proportions
of wind energy are captured as heat.
Diesel Retrofit
The main features of modular control and integration unit, is that it s designed to be connected to
an existing power plant. In this instance the switchgear is integrated into the design to reduce
future costs, and maximizing the use of the existing facility. New gensets can then be added into
the old of new powerhouse as required, with a minimum of new cabling and modification. This
design anticipates the installation of new generators sets, which can operate efficiently over a
range of load conditions in parallel operation with the wind turbines. The control system and
power electronics design would select the most efficient generator to always be on line.
Wind Turbines
Cost estimates for turbine installation were developed after geotechnical investigations and load
analysis. Installation costs estimates were developed for several types of turbines. Gross annual
estimated energy production for each turbine was arrived at through comparison of power curves
and wind resource information using HOMER. The results are summarized in Table 4. A 20-year
investment horizon and a 5% nominal interest rate were used for economic analysis. These are the
same investment guidelines as proposed in the Alaska Rural Energy Plan, April 2004.

Wind Diesel Integration and Balance of System:
The existing plant control system senses the load an automatically dispatches the most efficient
generator set or combination of sets to meet the load. Additions to the power system will need to
be made to accommodate high wind penetrations.
Basic Stabilization and Functionality
The Control and Power conditioning module consists of an large inverter which can provide
instantenous response to changes in system voltage. When couple to the lithium ion battery bank
the unit can provide up to 250 kWhrs of real energy and 250 kVar of reactive power correction.
This system is electrically coupled to the power grid, and maintains power quality during
fluctuations in wind output, major changes in load, or through power system faults such as the loss
of all turbines, or the primary diesel generator. The battery energy storage and power electronics
interface combination by itself is capable of basic stabilization of both the voltage and frequency
of the power system without any additional information from external sources. The power
conditioning system achieves stabilization through sensing of the grid and step-less absorption and
exportation of real power for frequency variation and reactive power for voltage support. The
energy stored in the batteries reduces cyclic loading and smoothes out short-term fluctuations as
the electric load and wind turbine outputs no matter how rapidly they change. This level of
stabilization translates into large savings due to the ability to operate smaller more fuel efficient
generator sets, lower diesel set points, reduced spinning reserve and diesel maintenance. It is
estimated that sufficient wind is available to allow the diesel gensets to be turned off for 2000
hours annually.
High Penetration Wind Systems
The sub second response of the power conditioning module is supplemented by the multisecond
response of the diesel generators. Other system changes can occur on the minute time frames, in
which diesel generators, and wind turbines can be reconfigured and loads in the community can be
turned on and off. The integration of the power system increases the value of the available wind.
Properly integrated advanced control capability decreases the contribution of the diesel generators
and provides more opportunity to use the powerconditioning system to ride through fluctuations of
the wind, and thus increase penetration. The integrated control system increases the value of all
the components in the system.
To enable the advanced features of grid stabilization for high wind penetration systems, and
maximum utilization of wind energy, the power conditioning and electric thermal storage units
must operate in a coordinated manner with the other major system components distributed
throughout the grid. This is done through a network of distributed integrated controllers. These
controllers on the ETS units are designed to respond to changes in system frequency, and thus
absorb and reject wind as required. Each ETS device is driven by advanced software applications,
which allows each component in the system to recognize and coordinate its activities with the
other controllers on the system.
The addition of an intelligent distributed network of component controllers which are linked by
high speed communications is a key feature in achieving optimising wind energy capture,
Renewable Energy Fund
Grant Application Round IV
AEA11-005 Grant Application Page 16 of 27 7/21/2010
improving efficiency, and getting the full benefit of every component in the system. The
controllers can be built into the automation controls of the power plant or can be provided as an
overlay, that works with and existing system.
Diesel Generator Monitors
Monitoring modules are interfaced to the existing generator controllers. These modules send
information back to the Power conditioning and control module about the current state of the
generator (running, stopped, on-line or off-line) as well as how much power the generator is
delivering if it is on-line.
Using a power transducer tapping in to existing current transformers (CT’s) and potential
transformers (PT’s) the monitoring device informs the system supervisory controller of how much
power is being generated, as well as how much spinning reserve is available on-line.
Wind Turbines
The wind turbines are provided with a customer interface to the wind turbine controller (WTC).
Monitoring modules are added in order to communicate with the wind turbines. These modules
send information and receive information such as the state of the machine (running, stopped, on-
line and off-line, power generated, alarms, nacelle position, etc.) back and forth between to the
system supervisory controller and the other individual controllers. Typically instruction include,
starting machines, stopping machines, reducing the power output of the machine through pitch
regulation or power set point control. The WTC would communicate via fiber optic cable.
High Renewable Penetration Operation Modes
High Renewable Penetration operation occurs under the following three distinct modes:
1. Diesel + Power Conditioning module
2. Diesel + PowerConditioning + Maximum Wind Turbine
3. Diesel + PowerConditioning + Limited Wind Turbine
Heat Recovery and Demand managed devices
This system is designed so that output of the wind farm typically exceeds the electric requirements
of the community. Under these conditions wind turbine output can be curtailed, and loads can be
managed to capture or control this energy. Two methods are available in this configuration, heat
recovery and demand control.
At the school, an electric boiler and a frequency response controller, would be installed. The boiler
grid interface uses the electric boiler elements, and a variable load controller system to provide
very fast frequency, voltage and power factor correction and capture of excess wind energy. This
boiler power demand would be controlled and used to respond to balance the power system during
times of collapsing wind power generation. In this instance the boiler captures up to the first 200
kW of wind energy and follows the load very closely, balancing the energy generation. To the
demand through direct frequency control. The boiler is assist the powerconditioning and battery
system, by rapidly absorbing longer bursts of energy, on a much smaller scale. The electric heat
recovery boiler would be plumbed into the existing heating system, and regulated as part of the
heating system, using the same thermostatic controls. Excess wind energy when available would
be captured in this boiler and the heat used to offset fuel costs of running the community buildings.

The school represents a large interruptible energy storage system. The heat recovery load at the
high school will require separate metering and service panel, including cables, breakers, and
breakers. The system would use the existing temperature controls and act as demand managed
devices controlled through the master control overlay. The method of communication proposed is
Ethernet.
Major community buildings with large heating requirements, such as the school, city offices,
clinic, city shop, and water and sewer treatment facilities represent potential customers with large
heat demand could also benefit from excess energy produced by an expanded wind plant.
Electric Thermal Storage
An average home in Kipnuk uses over 760 gallons of heating fuel annually. During a windy week
in the winter a single home can consume and entire 55 gallon drum of heating fuel. This project
proposes to capture the wind and use it to heat homes, throughout the year using Electric Thermal
Storage (ETS). ETS is the method of capturing excess wind generated electricity as heat and
storing it for use at a later time. An ETS unit, is an insulated metal box, about the same size as a
Toyo Stove, which contains electric heating elements which lie within special, high-density
ceramic bricks. These bricks are capable of storing vast amounts of heat for extended periods of
time. During periods of excess wind energy, a signal from the power plant supervisory controller
is sent to the metering system. The meters then enable the relays which turn on elements which
heat the bricks. Operation of the system is completely automatic. A sensor monitors the outdoor
temperature to regulate the amount of heat the systems stores in the bricks. A thermostat regulates
the delivery of the heat to the room. Each unit has a built in microprocessor that allows the owner
to configure the operation for their needs. There are over 100,000 of these units in operation in
the mid-west states and off-peak heating is common in Europe. The system provides a lower cost
low maintenance method of home heating.
The village would likely be on an 8-hour charge schedule, with supplement charging in periods of
high wind. An individual room-heating unit can both produce and store up enough energy on an 8
plus 2 charge schedule to output 20,000 Btu/ per hour per unit, 24 hours per day. This is similar in
size and energy output of a Toyo Stove. The dimensions are 58 inches in length, 24.5 inches in
height, and 10.5 inches in depth, and when filled with heat charge bricks each unit weighs 690 lbs.
The room units (shown above) are non-ducted and are designed to heat the room or area into
which they are placed. These heaters can be used in new construction applications or as a retrofit
or supplement to an existing heating system, and only require an electrical connection to operate.
Stored heat is circulated evenly and quietly by a fan inside the unit as the room thermostat calls for
heat. Individual units are easy to operate and requires very little maintenance. The amount of heat
stored in the brick core of the heater is regulated (either manually or automatically) according to
seasonal weather conditions using an outdoor temperature sensor and an onboard microprocessor.
The Smart metering system enables the ETS to charge, and allocates the costs differently between
off-peak wind and diesel only generation. The metering system working with control signals from
the diesel plant insures that customers are only charged for the reduced rates excess wind rate for
heating. .

This project proposes to install 180 residential room heaters. Because of the poor condition of
many electrical service entrances, upgrading of approximately 100 service entrances are required.
The budget includes the replacement of 100 service entrances and meter bases in order to receive
the
Metering system
Wind/thermal storage requires a method of notifying the stoves of the availability of low cost
wind energy, and a way to account for the difference in cost of wind versus diesel generated
electricity. This is done through new meters, which will be placed on each home. The
proposed metering platform creates a wireless communications link, which provides fully
automated, intelligent two-way communications between the power plant and each meter.
The advanced meters offer many additional features that will allow the utility to be managed
more effectively, and optimize diesel station operation.
The metering system will consist of 3 collector meters, one at the school, one at the
washeteria/water plant, and the last at the powerhouse. Each residential customer will have a
single-phase meter at their home. These meters will communicate with the data collecting 3 phase
meters to create a mesh network. The meters are designed for plug and go capability, which
eliminates programming and simplifies installation. This same metering system has been selected
for use as it has proven to be a best practice management tool for the Alaska Village Electric
Cooperative.
Three of the most important features are:
1. Demand control capability that allows the utility to control thermal storage devices remotely.
Thermal stoves will be enabled for green energy pricing only when a signal from the utility
indicates that an excess of wind energy is available. The meter can switch devices the stoves on
and off according the amount of excess wind energy available. The meters can also control other
electrical devices such as water heaters and/or controlling lighting or thermostats.
2. User interface. The meters come with an in-home display device that can be used to inform the
customer about their cost and energy usage. In the future they can be enabled to enter credit card
information to pay bills directly.
3.Pre payment option; the proposed meters can be configured with a prepay option, which requires
consumers to pay in advance of use. This feature is requested by small utilities, because it
mitigates the financial risks associated with power sales and reduces embarrassing utility
disconnects, billing disputes and damage to local relationships. When coupled with the associated
user display in each home, the system improves financial management for both the utility and the
customer. The in-home display allows utility customers to self manage energy use through real-
time, informed decisions about consumption. When combined with the user interface, most
customers are typically very satisfied.
The need for low cost residential heating represents the largest potential load for the Utility. The
mine will operate motors, pumps, heaters, crushers, auxiliary generators and each individual
component by itself can be responsible for very large loads. Control modules can be added to
these load centers integrate the operation of the mine with the wind diesel system. To obtain the
full benefit and for safety, a demand signal/control is introduced to prevent loads from coming on
when the power system has insufficient generation on line and to keep engines from running
inefficiently and especially for loss of load protection.

4.3.2 Land Ownership
Identify potential land ownership issues, including whether site owners have agreed to the
project or how you intend to approach land ownership and access issues.
The land needed for the project has been given to the utility by the village corporation.
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
The construction of the wind and power project will require some of the following review and/or
permitting, no potential barriers have been identified.
1. Coastal Project Questionnaire
Since Kipnuk is located in a coastal zone, the project requires submittal of a Coastal
Project Questionnaire to the State of Alaska, Department of Natural Resources
(DNR). The DNR coordinates review of the questionnaire by various state
agencies and assists in identifying required permits pertinent to the project. The
standard review spans about a 30-day period.
2. Fire Marshall Plan Review
The construction of the new power generating facilities will require submittal of a
complete set of construction documents to the State of Alaska, Department of
Public Safety, Division of Fire Protection (Fire Marshal) for plan review and
approval. The State Fire Marshal then issues a Plan Review Certificate to verify
compliance with adopted Building, Fire, and Life Safety codes. Final stamped
drawings must be submitted along with the application fee for project review.
Anticipate a minimum of one month before comments may be received from Fire
Marshal.
3. Alaska Department of Transportation
If the construction of a tie-in to the existing electrical distribution system fails
within an existing Department of Transportation (DOT) right-of-way, a utility
permit from the DOT will be required.
4. Alaska Department of Environmental Conservation Review
The Alaska Department of Environmental Conservation (ADEC) regulates the
operation of diesel power generation facilities by a consistency review process. The
Application for the Pre-Approved Limit Diesel Generation Facility must be
submitted prior to the facility startup, provided that the nitrogen dioxide emissions
do not exceed 100 tons/year. The review is set up to accommodate future growth of
Renewable Energy Fund
Grant Application Round IV
AEA11-005 Grant Application Page 20 of 27 7/21/2010
a power plant, provided that the growth is requested during the initial application,
and it does not exceed the 100 ton/year on nitrogen oxide emissions. Power plants
which fall into the sizes necessary for Alaska villages will not exceed the 100
ton/year level. The addition of the Wind System will significantly reduce the
emissions of harmful air pollutants.
5. Regulatory Commission of Alaska Certification
The Regulatory Commission of Alaska (RCA) regulates public utilities by
certifying qualified providers of public utility and pipeline services and facilities at
just and reasonable rates, terms, and conditions. This keeps rates as low as possible
while allowing the utility to earn a fair return. The commission also determines the
eligibility and the per kilowatt-hour support for electric utilities under the Power
Cost Equalization program.
6. State Historic Preservation Office
The State Historic Preservation Office (SHPO) is required, under Section 106 of the
National Historic Preservation Act, to review any state of federally funded project
for potential of disturbing cultural resources.
7. Federal Requirements
• U.S. Fish and Wildlife Service
The U.S. Department of the Interior Fish and Wildlife Service will require that any
construction project be reviewed for impact to endangered species. The Fish and
Wildlife Service has been consulted with respect to this project, and has requested
further review due to the known presence of listed species and/or designated critical
habitat in the action area, or to the suspected presence of listed species in the
vicinity of the action area. Because of the absence of federal funds no formal
consultation is required.
• U.S. Army Wetlands Permit
Projects that disturb or place fill material on existing soil requires a request for a
wetlands determination from the U.S. Army Corps of Engineers and, if found to be
wetlands, application for a Department of the Army Permit must be submitted for,
and granted, before construction begins.
• Federal Aviation Administration Review
Projects located less than 5 miles from a runway or airport, such as this Wind
System, should complete Form 7460-1, “Notice of Proposed Construction or
Alteration,” and submit all necessary elevation and height of structure information
to the Federal Aviation Administration (FAA), Alaska Region, prior to
construction. The FAA reviews the plans and determines whether the construction
of project will present a hazard to air traffic in the vicinity. The FAA is very
responsive and typically provided project determinations within one week of the
completed form submittal.

• Bureau of Indian Affairs
If the construction of a tie-in to the existing electrical distribution system falls
within an existing right-of-way through Native allotment(s), a permit from the
Bureau of Indian Affairs (BIA) will likely be required.
• Federal Regulatory Commission
If the construction of a tie-in to the existing electrical distribution system falls
within an existing right-of-way through federal lands, a utility permit from the
Federal Energy Regulatory Commission (FERC) may be required.
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
Since the land for the project has been selected by the local village corporation, and there no
Federal money involved, no significant filling of wetlands is to take place there are no endangered
species present, there are no anticipated conflicts or threats to migratory birds, the sites selected
are do not represent hazards to flight operations, and are not located in archeological sensitive
areas.
After contacting the USFWS, the FAA and the Corp of Engineers, it is determined that no permits
to construct this project are needed. In each location, the power lines to the wind turbines will
extend underground from nearby 3-phase power. No power poles will be installed and no aerial
transmission lines, that could present a hazard to migrating birds, are being constructed. The Corp
of Engineers will place the wind turbines on pile foundations, which will not require any filling of
wetlands, and do not require a Section 404 permit. It is not anticipated that any of the Chaninik
projects will interfere with or result in the mortalities of any endangered species or migratory
birds. The USFWS, Corp of Engineers, FAA and State permitting agencies have been contacted.
USFWS concerns have requested that power lines be buried if possible, and to refrain from using
guyed towers, to maintain lattice towers by keeping them free of raven nests. Preliminary locations
were presented to the FAA, and they have requested a final review of the selected sites, and that
the wind turbines be surveyed in, within one month of installation. We will be providing the
USFWS, the Corp of Engineers, the FAA and the Alaska State Division of Governmental
Coordination. Andrew Grossman has been hired as an environmental consultant for the Chaninik
Wind Group projects. He is retired USFWS and NMFS biologist experienced in permitting of
construction projects in Alaska.

many options, which range from complete coverage and performance guarantees. A budget of
$1000 per month per turbine, or $.02/kWhr per year is set aside. The cost of the turbine includes
one week of factory training for two local operators, and one week on site training. The turbines
have advanced diagnostic package with remote diagnostics which enable full time monitoring,
remote programming and remote technical assistance.
Turbine Maintenance:
Maintenance can be divided into three categories, routine, unscheduled and scheduled.
Routine maintenance is required to maximize performance, maintain safety, and ensure a full
operating life of each turbine. An estimate of the cost of annual and 10 year maintenance is
provided below. This installation cost estimates include a cost for specialists to be brought in for
the first year to perform these functions, and provide additional on-site specialized training to local
personnel.
This estimate includes setting aside an amount annually for extended and unscheduled
maintenance. Excluding major component inspections and replacements, the following
maintenance schedules generally apply to each turbine type.
Weekly and Monthly Inspections:
Bi-Annual Inspections and Service:
10 year inspections:
Every 10 years the wind turbines should be thoroughly inspected. Particular attention should be
paid to the blades. Most manufacturers recommend that the blades be removed and deflection
tested for integrity and strength. This exercise can be conducted using a tower attached jib crane.
Each blade would be removed and lowered to the ground, where the blades would be placed in a
jig and tested for deflection. At this time the blades would be replaced, resurfaced, and repaired as
needed.
Repair and replacement fund for failure of major components.
An annual replacement account will be set aside to replace major components on the turbine. This
set aside account would be based on an annual production estimate of $.02/kWhr. This amount
could be readjusted based on rising costs and the comparable cost of fuel.
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 Purchases:
Kipnuk Light Plant provides electricity to the community and holds the certificate of public
convenience.
A household survey was conducted and the results indicate that residential customers are desperate
for lower cost heating options, as heating fuel is becoming unaffordable at $ 8.00 per gallon.
Electric Thermal Storage is a method by which excess wind generated electricity can be stored as
heat so that it can be used 24 hours per day. The excess wind energy will be offered to customers
at between $ .08 to $.15/kWr, which is equivalent to heating oil equivalent of $ 2.60 to $ 5.00 per
gallon assuming that # 2 heating fuel with 138,000 btu/gallon and with a highly efficient furnace
with 95% conversion efficiency. Since there is no local wood, or peat or coal, wind heat in this
application will be the lowest cost heating source, and highly desirable.

Complete the cost worksheet form which provides summary information that will be considered
in evaluating the project.
See attached cost worksheet.
SECTION 5– PROJECT BENEFIT
Explain the economic and public benefits of your project. Include direct cost savings,
and how the people of Alaska will benefit from the project.
The benefits information should include the following:
• Potential annual fuel displacement (gal and $) over the lifetime of the evaluated
renewable energy project
• Anticipated annual revenue (based on i.e. a Proposed Power Purchase Agreement price,
RCA tariff, or cost based rate)
• Potential additional annual incentives (i.e. tax credits)
• Potential additional annual revenue streams (i.e. green tag sales or other renewable
energy subsidies or programs that might be available)
• Discuss the non-economic public benefits to Alaskans over the lifetime of the project
Diesel fuel used to generate electricity in Kipnuk is expected to grow from the present level of
150,582 gallons, to 198,000 gallons annually by 2015.
This project is estimated to generate 2,048,682 kWhrs of electricity with wind. This will be used
in conjunction with the flywheel to displace 90,900 gallons of fuel used to generate electricity and
another 24,000 gallons of fuel used for heating. (90,900 x $5.00 = $454,950, plus 24,000 gallons
x $6,00/gal for heating fuel = $144,000. The flywheel reduces the diesel run time of the most
expensive Caterpillar engine by 4000 hours, which results in doubling its replacement interval, this
saving is estimated to be $154,43. 4000 hours x 12.50 per hour, plus ½ of $200,000 replacement
costs. In the early years of the project, this energy will be used to displace heating fuel, but as the
load grows more fuel used for power generation will be displaced.
The estimated project benefit is $753,389 less the additional incurred maintenance costs that are
estimated at $48,000 per year. The total financial benefit is $705,389:
Large wind with thermal storage, provides three benefits, decreased dependency on fossil fuels
means more dollars stay in the community. Wind heat has the potential to increase revenues to the

local utility while at the same time reducing home heating costs.
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
The Chaninik Wind Group is working to develop a regional wind system business plan, based on
a cooperative business model. The primary elements of this plan include utilizing combined
funding from the savings of displaced diesel fuel to pay for system maintenance, and overall
administration. The greater the number of wind turbines, the more fuel displaced, the more viable
the will be the financial strength of the group.
One of the principles of successful operation will be to create a well-paid job in each community
to support the wind system operation, and to create a network of trained operators, one in each
village who can support each other.
A proposed source of funding would be to allocate $.05 per kilowatt hour for wind production to
the operation and support. Each wind turbine will conservatively produce 150,000 kWhrs
annually. This would be $30,000/turbine x 3 turbine = $37500 in additional wages to utility
personnel. Another $.03 / kWhr would be dedicated to a replacement fund. However, a
production bonus would be paid to the utility personnel for any kilowatt hours produced above
200,000 kWhrs per year. This production bonus would be $.10/kWhrs. This could be as much as
$10000 per turbine or $10,000. The increased cost of turbine operations would be partially paid
for through the turbine bonus, increased non-fuel operating costs provided in the PCE program,
and through fuel savings. The customer would still see a significant decrease in electrical rates,
as the current value of kilowatt of displaced fuel is in the range of $.30/kWhr.
The Chaninik Wind Group would administer the overall business plan with the assistance of the
