2.4 Project Description
Provide a brief one paragraph description of the proposed project.
Ouzinkie currently operates a makeshift hydroelectric operation that has served the village for many
years. However, the dam failed in the fall of 2013 even while a new project was being planned to
replace the dam. The proposed project in Ouzinkie will work to install new hydroelectric capacity in
conjunction with the recent new dam construction. A new Ossberger 150 KW hydroelectric turbine
will be installed to maximize electrical generation in the community. The turbine is to operate
efficiently at flow rates from 2 cfs to 10 cfs.
2.5 Scope of Work
Provide a scope of work detailing the tasks to be performed under this funding request. This
should include work paid for by grant funds and matching funds or performed as in-kind match.
Under this funding request, a new Ossberger 150 KW hydroelectric turbine and generator module
will be purchased, shipped, and installed in Ouzinkie.
ANTHC will perform Project Management and utilize either internal resources or identify an
appropriate contractor for shipping and receiving, engineering, installation and other tasks
associated with the project. It is anticipated a very minimal design effort will be required to install
the new turbine.

3.2.3 Cost Justification
Indicate the source(s) of the cost estimates used for the project budget.
The cost estimates presented in the table below represent the anticipated costs of the proposed
system, taking into account recent design and construction costs of similar projects. Large financial
risks are associated with construction work in rural Alaska. Expenses for potential changes in site
conditions, unknown or unforeseen issues, and logistics have been incorporated into these costs.
ANTHC’s match may actually work out to be much higher than shown, as this work may be
performed at ANTHC’s billing rate and may exceed the hours anticipated.
Any excess time/value of the project management in-kind match does not replace other financial
cost elements of this project. The anticipated dates of completion are assumed based on the
likelihood of funding, other ongoing work in the city, and other work going on around the state.
3.2.4 Funding Sources
Indicate the funding sources for the phase(s) of the project applied for in this funding request.
Grant funds requested in this application $ 397,427
Cash match to be provided $ 0

Total costs for project phase(s) covered in application (sum of above) $ 401,441
3.2.5 Total Project Costs
Indicate the anticipated total cost by phase of the project (including all funding sources). Use
actual costs for completed phases.
Reconnaissance $0
Feasibility and Conceptual Design $0
Final Design and Permitting $ 14,625
Construction $ 386,816
Total Project Costs (sum of above) $ 401,441
3.2.6 Operating and Maintenance Costs
O&M costs can be estimated in two ways for the standard application. Most proposed RE projects
will fall under Option 1 because the new resource will not allow for diesel generation to be turned
off. Some projects may allow for diesel generation to be turned off for periods of time; these
projects should choose Option 2 for estimating O&M.
Options O&M Impact of proposed RE project
Option 1: Diesel generation ON
For projects that do not result in shutting down
diesel generation there is assumed to be no
impact on the base case O&M. Please indicate
the estimated annual O&M cost associated with
the proposed renewable project.
$0 The new turbine will likely require less
maintenance than the existing turbine, which
faces constant problems.
Option 2: Diesel generation OFF
For projects that will result in shutting down
diesel generation please estimate:
1. Annual non-fuel savings of shutting off
diesel generation
2. Estimated hours that diesel generation
1. $0
2. Hours diesel OFF/year:

number, size, age, efficiency, and type of generation.
Currently there are three diesel generators in operation in Ouzinkie: a 60 KW generator, a 100 kW
generator, and a 190 kW generator. The existing hydro turbine and generator module has a
maximum capacity of 125 kW and is past its useful life. .
The production of the various generators varies greatly by month. In general, the more hydro -
electric power that is produced, the less the larger generators are used.
The current hydroelectric production varies from producing 40,000 kWh per month at max capacity
to producing 0 kWh. In recent years hydro-electric capcity has been shut down as much as 30% of
the time. Future shutdowns for frequently required maintenance are expected to increase based on
the turbine/generator set that was installed in 1988 reaching the end of its useful life.

5.4.2 Future Trends
Describe the anticipated energy demand in the community over the life of the project.
Ouzinkie energy demand has been slowly trending up for years. Total kWh consumption in 2014
was 761,077, while total kWh consumption in 2005 was 746,594. This represents a total increase of
14,483 or 2% over 10 years.
Ouzinkie is planning the development of a ferry terminal, fish processing facility, and commercial
greenhouse. These developments would require significant electrical generation.
5.4.3 Impact on Rates
Briefly explain what if any effect your project will have on electrical rates in the pr oposed benefit
area over the life of the project. For PCE eligible communities, please describe the expected
impact would be for both pre and post PCE.
Increasing the portion of the community’s electricity generated from hydro as opposed to diesel will
lower the cost of electricity in the community. This should save the need for PCE subsidies from
the State of Alaska as well as provide lower rates for non-PCE commercial users. With multiple
non-PCE eligible potential additional commercial consumers looking to move into the community,
the lower total rate could be significant for economic development in the community.
5.4.4 Proposed 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
Integration plan
Delivery methods
At maximum capacity the Ossberger turbine can produce 150 kW of power, occasionally
carrying 100% of the community of Ouzinkie’s electric load.
Anticipated capacity factor : 64%
Anticipated annual generation of this project is 475,750 KWH, a 358,111 increase in marginal
kWh increase over existing turbine based on 2014 PCE data.
Anticipated barriers: None.
Basic integration concept: Integration with the diesel plant as a hybrid operation. The
hydroelectric is to make up the base electrical production with the diesel generators providing

SECTION 6 – ECONOMIC FEASIBILITY AND BENEFITS
6.1 Economic Feasibility
Criteria: Stage 2-4.A: The project is shown to be economically feasible (net positive savings in fuel,
operation and maintenance, and capital costs over the life of the proposed project).
6.1.1 Economic Benefit
Explain the economic 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:
Anticipated annual and lifetime fuel displacement (gallons and dollars)
Anticipated annual and lifetime revenue (based on i.e. a Proposed Power Purchase Agreement
price, RCA tariff, or cost based rate)
Additional incentives (i.e. tax credits)
Additional revenue streams (i.e. green tag sales or other renewable energy subsidies or
programs that might be available)
The economic model used by AEA is available at
http://www.akenergyauthority.org/Programs/Renewable-Energy-Fund/Rounds#round9. This
economic model may be used by applicants but is not required. The final benefit/cost ratio used
will be derived from the AEA model to ensure a level playing field for all applicants. If used, please
submit the model with the application.
The annual projected diesel fuel to be displaced is estimated at a total of 475,750 kWh, or 36,068
gallons of fuel, given 13.19 kWh/gal diesel fuel efficiency based upon 2014 PCE Data.
The improvement over existing hydro production (identified in the 2014 PCE data as 117,639 kWh)
would be 358,111 kWh, or 27,151 gallons of fuel at the 13.19 kWh/gal diesel fuel efficiency
measured for 2014 PCE. At the current rate paid for fuel of $2.85, this amounts to an annual savings
of $77,380.
This will lower the electricity cost, provide a sustainable power source, reduce run time of diesel
generators, and reduce emissions normally created from power production. Additionally, there is
potential that the benefit may improve in the future as the precipitation trends have been increasing
and the long term projections indicate that this trend will continue due to changes in the local
climate.
6.1.2 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
Identify the potential power buyer(s)/customer(s) and anticipated power purchase/sales price
range. Indicate the proposed rate of return from the grant-funded project.
Rates will be adjusted as is required by the regulatory commission. This project will fit in with
existing electrical sales from the City of Ouzinkie Utility and will not be directed to a single user.

6.1.3 Public Benefit for Projects with Private Sector Sales
For projects that include sales of power to private sector businesses (sawmills, cruise ships, mines,
etc.), please provide a brief description of the direct and indirect public benefits derived from the
project as well as the private sector benefits and complete the table below. See section 1.6 in the
Request for Applications for more information.
The proposed project will benefit the community by reducing fuel expenses at the power utility by
$77,380 per year, through avoided diesel generator use. The project is anticipated to supply the
community with 475,750 KWH per year through hydroelectric production. This in turn reduces run
time on the diesel generators, extending the equipment’s lifespan, and reduces C02 emissions in the
community from diesel generation.
This project could potentially encourage development of a planned ferry terminal, commercial
greenhouse, and fish processing for the community. Lower prices to these potential users oculd
generate local jobs, increase quality of life through ease of transportation, and provide local healthy
food to the residents of Ouzinkie.

6.2 Financing Plan
Criteria: Stage 2-4.B: The project has an adequate financing plan for completion of the grant-
funded phase and has considered options for financing subsequent phases of the project.
6.2.1 Additional Funds
Identify the source and amount of all additional funds needed to complete the work in the phase(s)
for which REF funding is being applied in this application. Indicate whether these funds are
secured or pending future approvals. Describe the impact, if any, that the timing of additional
funds would have on the ability to proceed with the grant.
6.2.2 Financing opportunities/limitations
If the proposed project includes final design or construction phases, what are your opportunities
and/or limitations to fund this project with a loan, bonds, or other financing options?
The community is not interested in applying for financing for this project at this time.
6.2.3 Cost Overruns
Describe the plan to cover potential cost increases or shortfalls in funding.
ANTHC will make every effort to keep the project within the budget. In previous instances where
there were project overruns, ANTHC has successfully tapped into other funding opportunities to
make up the budget deficits. This would be the approach for this project as well.
6.2.4 Subsequent Phases
If subsequent phases are required beyond the phases being applied for in this application,
describe the anticipated sources of funding and the likelihood of receipt of those funds.

As mentioned in the attached feasibility study, the existing penstock in Ouzinkie has reached the
end of its useful life. ANTHC and the City of Ouzinkie will seek funding through alternative
sources to replace the existing functioning penstock.
6.3 Other Public Benefit
Criteria: Stage 3-4.C: Other benefits to the Alaska public are demonstrated. Avoided costs alone
will not be presumed to be in the best interest of the public.
Describe the non-economic public benefits to Alaskans over the lifetime of the project. For the
purpose of evaluating this criterion, public benefits are those benefits that would be considered
unique to a given project and not generic to any renewable resource. For example, decreased
greenhouse gas emission, stable pricing of fuel source, won’t be considered under this category.
Some examples of other public benefits include:
The project will result in developing infrastructure (roads, trails, pipes, power lines, etc.) that
can be used for other purposes
The project will result in a direct long-term increase in jobs (operating, supplying fuel, etc.)
The project will solve other problems for the community (waste disposal, food security, etc.)
The project will generate useful information that could be used by the public in other parts of
the state
The project will promote or sustain long-term commercial economic development for the
community
As Ouzinkie seeks to improve its economic situation, a more stable, lower cost price of electricity
would dramatically improve the community’s chances of local economic development from fish
processing, a ferry terminal, and a commercial greenhouse. Development of these local
opportunities could dramatically increase the amount of local jobs.

SECTION 7 – SUSTAINABILITY
Describe your plan for operating the completed project so that it will be sustainable throughout its
economic life.
Include at a minimum:
Capability of the Applicant to demonstrate the capacity, both administratively and financially, to
provide for the long-term operation and maintenance of the proposed project
Is the Applicant current on all loans and required reporting to state and federal agencies?
Likelihood of the resource being available over the life of the project
Likelihood of a sufficient market for energy produced over the life of the project
City employees will conduct periodic maintenance such as cleaning intake screens, monitoring
water levels and production numbers, troubleshooting reported problems etc. Specialized
contractors will be engaged when specialty work is required on the actual turbine. Project
constructed infrastructure maintenance will be financed out of electrical rate collections from
existing and future customers in Ouzinkie. Rates should eventually decrease from the increased
hydroelectric production.
Integration of existing diesel generation will need to be appropriately controlled to ensure proper
switch gear operation and to minimize power distribution disruptions.
SECTION 8 – PROJECT READINESS
Describe what you have done to prepare for this award and how quickly you intend to proceed with
work once your grant is approved.
Specifically address your progress towards or readiness to begin, at a minimum, the following:
The phase(s) that must be completed prior to beginning the phase(s) proposed in this
application

Procuring all necessary equipment and materials
If this project is funded, final design efforts are planned for the winter of 2016. Shortly thereafter
materials will be ordered and shipped to the community so that construction can commence in the
summer of 2017.
The new dam at Mahoona Lake in Ouzinkie is complete as of September 2014, and was funded by
the Alaska Legislature. The new dam in Ouzinkie will increase the amount of water available for
storage in Mahoona Lake from the levels of the failed wooden dam.
A design for a new penstock that would further increase momentary flow availability and reliability
for the hydroelectric turbine and generator in Ouzinkie is completed to the 65% level as part of the
project to replace the dam at Mahoona Lake.
No permits are anticipated for this effort, and no new land access is required for this project.
Limited materials are anticipated to be needed, and a suitable turbine and generator are already
selected and price quoted for this project.

BACKGROUND
The decommissioned existing hydro-electric system in Ouzinkie was constructed in 1986 by a
private contractor to sell low cost electricity to the community. The dam was a composite wood,
steel, concrete and rock fill structure that was used to increase the water storage capacity of
Mahoona Lake and to divert water to the 125kW hydro-electric turbine. The penstock was
constructed using thin walled plastic sewer pipe and the turbine was housed in a shipping
container to reduce construction costs. The system has served the community well for almost 30
years until the dam failure in the fall of 2013. The turbine consumed about seven (7) cubic feet
per second (cfs) of water when operating at full capacity and requires approximately five (5)
acre-feet of water to produce about 1000 kW of electrical power. Ownership of the dam,
penstock and hydro-electric turbine was transferred to the City of Ouzinkie (City) in 1993.
On June 10, 2011 the State of Alaska, Department of Natural Resources, Dam Safety and
Construction Unit conducted a field inspection of the Mahoona Dam. The field inspection report
for the site visit noted concerns about the structural integrity of the wooden supports and
degradation of the dam face.
Prior to June 2011, a private engineering contractor had been retained by the City to conduct
periodic safety inspections of the Mahoona Lake dam. On September 15, 2011, the engineering
contractor inspected the Mahoona Lake dam subsequent to a significant rainfall event that caused
some flooding in the community. The dam spillway had become clogged with debris and the
dam filled to a water level above the normal operating point. The event stressed the wooden
supports resulting in additional damage to the already compromised wooden structure. On
September 27, 2011 a letter was issued by the contactor to the City noting that “the structure has
been further evaluated and confirmed to be deteriorated to the point where operation at full
reservoir level is unwise”
In early 2012 ANTHC partnered with the City to complete the design of a new dam and to
pursue funding to replace the deteriorating dam. The design incorporated some of the structural
elements of the existing dam in order to reduce construction costs. Because of the seismic risk in
the area and the amount of water impounded by the dam, the new facility was designed
conservatively as a concrete faced rock fill (CFR) dam. ANTHC’s cost proposal for the new
CFR dam was approximately 60% lower than a competing cost proposal the City received from a
private contractor.
In early 2013 the city was successful in obtaining funding from the State of Alaska to build the
3
new dam. Construction was scheduled to begin in April 2014. In mid-March 2013 a breach
formed in the old dam. The breach was caused by a tree stump that had floated up to the dam and
punched a hole through the rotted wooden face. Because of the dam breach, the construction
scheduled was accelerated. Completion of the new dam is scheduled for September 2014.
EXISTING ELECTRICAL SYSTEM
The City’s total electrical consumption over a two year period is illustrated in Figure 1 in
Appendix A. Figure 1 indicates that electrical consumptions peaks in the middle of the winter,
and is lowest in the summer. The variation in demand is likely due to lower lighting and heating
demands in every sector of the community, as well as a large drop-off due to the reduced usage
of the school during the summer.
The City’s electrical consumption can be broken down in to three categories, residential,
commercial, and governmental. These are based on power cost equalization (PCE) definitions.
Residential is entirely homeowners, who are eligible for power cost subsidies up to 500 kWh per
month. Commercial users are businesses and some state and federally funded facilities which are
not eligible for PCE (including the school). Governmental facilities are primarily city owned
facilities, but also include the health clinic.
The largest consumer of electricity in the community is residential (see Figure 2, Appendix A).
Residential also has the lowest variation in consumption. Commercial is the second largest, but
has significantly more variation in consumption, primarily due to the school being significantly
lower in the summer. Governmental consumption fluctuates largely due to the electrical usage of
street and harbor lighting, but makes up the smallest portion of electrical consumption overall for
the community.
Over the course of the year, residential makes up 45% of electrical consumption, commercial
36%, and governmental 19% (See Figures 3, 4 and 5 in Appendix A). This however is
substantially different seasonally. (Summer defined as June, July August. Winter defined as the
rest of the year)
While electrical consumption rises across all sectors during the winter, the increase in
governmental and commercial facilities is far greater.
Sector Active Meters Average Monthly Consumption (kWh)
Residential 90 288.97
Commercial 23 907.18
Governmental 15 752.13
4
While residential makes up the primary electrical consumption base, the largest single users are
primarily governmental and commercial users.
Electrical Generation
The City’s electrical utility has in the past generated electricity from a mixture of diesel and
hydro-electric sources. The utility owns three diesel generators, a 60 KW generator, a 100 kW
generator, and a 190 kW generator. The decrepit existing hydro-electric generator has a
maximum capacity of 125 kW.
The production of the various generators varies greatly by month. In general, the more hydro-
electric power that is produced, the less the larger generators are used (see Figure 6, Appendix
A).
The old Hydro-electric production varied from producing 40,000 kWh at max capacity, to
producing 0 kWh. Hydro-electric production is the primary variable in determining how much
diesel generation capacity is used (see Figure 7, Appendix A). In recent years the hydro-
electricity has been shut down as much as 30% of the time, with future shut downs expected to
increase based on the turbine/generator set installed in 1988 reaching the end of its useful life
Hydro-electric power on average made up 28% of the electrical production with the old turbine
and generator in the community. Line losses average 9% and did not vary based on the primary
source of electrical generation (see Figure 8, Appendix A).
Hydro-electric Capacity
If Hydro-electric power could produce at its 40,000 kWh/month max regularly, it would meet
50% of the winter time load of the community, and 75% of the summer time load.
To be able to meet the communities current electrical demands 100% with hydro-electric power.
Hydro-electric production would have to be increased to 55,000 kWh/month in the summer and
72,000 kWh/month in the winter. However, the amount of water from the watershed is not
sufficient to support this all of the time.
Residential electrical consumption dips in the summer on the whole. This effect is mitigated by
the presence of some seasonal residents who are typically fairly large users. The decline in
consumption is unfortunately minimized due to the increase in residents (see Figure 9, Appendix
A).
SYSTEM DEFICIENCIES
The existing turbine is aging and requires constant maintenance to keep it operating. Even with
diligent maintenance, the City of Ouzinkie reports that the system was down for repairs or
5
waiting on parts on average 30% of the time each year. The existing turbine is also not properly
sized to take full advantage of the limited watershed that feeds Mahoonah Lake.
The existing turbine is oversized and operating inefficiently during the majority of the year when
flows from the watershed cannot support operating the turbine at full capacity. From the
precipitation vs. flow rate analysis (see Figure 2, Appendix B), it can be noted that operating the
turbine at full capacity can only occur for a limited number of days each year after a significant
storm event. The system can operate at full capacity on average only 5% of the year and at
approximately 40% of its capacity or less over more than 55% of the time each year (Alaska
Climate Summaries, 1973-2006).
The bottom line is that the hydro-electric turbine is oversized for the watershed and needs better
controls to take advantage of equalizing heavy precipitation events. Ideally all water entering the
lake would flow through the penstock and not over the dam spillway. A turbine system that is
capable of operating efficiently at both high and low flow rates will increase the amount of
power that can be produced from water flowing down the penstock. Preventing water loss over
the spillway by using a control system with a sound operating strategy, that considers the
hydraulics of the watershed, will maximize the amount of power that can be produced by the
system. Finally, a new system that is not plagued with breakdowns will ensure the turbine is
available to operate when the water resource is available. From the previous discussion on
hydro-electric capacity, it should be noted that a properly designed and operated hydro-electric
facility can substantially reduce the City’s reliance on diesel electric power.
Water is sourced from Mahoona lake to supply the hydro-electric turbines using 5100’ of 18”
and 21” diameter PVC penstock. The penstock was constructed in the 1980’s using non-pressure
rated PVC sewer pipe meeting ASTM F679, ASTM F679 is only suitable for non-pressure
drainage of sewer and surface water. The pipe was poorly covered during construction and has
jacked and been pushed through time. Exposed pipe can be crushed by falling trees. Though the
transmission line has performed adequately, it is not rated for the pressurized water currenty
flowing through the pipeline and is at extremely high risk of failure.
A new penstock is essential and required to operate hydroelectric power in the community. This
transmission line is also the communities’ only source of water for their community water
system. Ensuring a stable supply of water to the community is critical for maintain access to
clean water for the community of Ouzinkie.
ANALYSIS OF ALTERNATIVES
In order to more effectively provide electrical power, the hydro-electric turbine should be a two-
celled 150 kW Ossberger turbine/generator set. The Ossberger turbine will generate a partial load
6
of its specified 150 kW by opening or closing the guide vane positions via the lake water level
controller. The current peak load is approximately 175 kW, which primarily occurs during the
winter. During the majority of the time, the Ossberger turbine will provide 75 kW of hydro-
electric supplementary power through either turbine. With this configuration, the efficiency of
the City’s power system can be optimized if a new 120 kW diesel generator is also installed.
However, the installation of a new diesel generator is not part of this project but should be
considered in the future.
Ouzinkie’s historic precipitation information is shown in Figure 1, Appendix B.
Due to the limited size of the watershed, the City cannot rely on hydro-electricity to provide
100% of the community’s electrical demands at a sustained level. However, it should be noted
that the amount of water passing through the hydro-electric turbine can occasionally be reduced
(see Figure 2, Appendix B). For example, when electrical demand is lower, the amount of water
passing through the turbine can be reduced resulting in water conservation and lower electrical
power production. The water flow rate through the turbine will be approximately 2.5-5 cfs. The
corresponding electricity generated from the aforementioned flow rate would be approximately
25,000-58,000 kWh (see Figure 3, Appendix B).
During higher precipitation, the hydro-electric power can run on full capacity at 150 kW without
utilizing a diesel generator.
During lower-than-average precipitation, the hydro-electric power needs to run on partial
capacity (approximately 75 kW) of the full capacity of 150 kW by utilizing either one of the
proposed turbine/generator sets in conjunction with a 120 kW diesel generator.
The turbine/generator analyses were performed as follows:
1. Ossberger Turbine (150KW): Install a new turbine/generator in the old hydro-electric
turbine/generator facility adjacent to the Ouzinkie power plant.
2. Quote from Hydropower Turbine Systems (HTS) Inc: $250,000 with existing switchgear
3. The technical data given by HTS indicates that the turbine’s peak mechanical efficiency
is approximately 81.4%. The estimated range of turbine efficiency for the new turbine is
an estimated 75% (lower flow rate) to 83% (higher flow rate).
4. Over the course of the year this turbine would generate 475,750 KWH of electricity.
Based on 2011 PCE data, Ouzinkie’s exsiting diesel generation has a KWH/gallon of fuel
efficiency of on average 13.155. 475,750 KWH would displace 36,151 gallons of fuel at
$4.74 per gallon for a total project benefit of $171,422.
A new penstock of 5,100 ft needs to be installed using 24” HDPE, SDR 15.5, butt fused
connections. This pipe is rated for water pressure application and has excellent freeze/thaw
characteristics. Proper installation practices should be followed to provide an adequate bury
7
depth below the frost line and for protection of the pipe. Other upgrades would include air relief
stations along the pipeline, a bypass line at the hydro plant, proper main line valves at the upper
and lower ends of the line, and adequate pressure relief in case of a line surge.
A construction cost estimate is attached for the construction costs of a new penstock. 65%
Design, including surveying for the new penstock has been completed with funding from the
State of Alaska for the Mahoona dam replacement. Completing design of the penstock would
require minimal effort.
CONCLUSIONS
Estimated construction costs include materials, equipment, freight, labor, design, construction
management, training and startup and testing. Cost was estimated based on recent project
experience.
All work at the hydro-electric turbine buildings, construction of the penstock, along with design
and construction management/administration for the complete project, is included in the Base
Project cost. Incremental costs for overhead and freight are estimated individually (refer to
attached cost estimates located in Appendix C).
The monthly electricity costs saved with the Ossberger turbine and penstock are illustrated in
Figure 4, Appendix B. The estimated annual community savings from generating hydro-electric
power in conjunction with existing diesel generation, is $171,422. . Based on the ratio of the
project cost to savings, the estimated simple payback is 14.5 years.
If this proposal is granted through the State of Alaska Renewable Energy Fund Grant Program in
the Round VIII, construction money for this project will be available in 2 years. With a 2 year
escalation rate of 3%, the respective estimated project cost in 2016 is $2,516,385.

Ouzinkie
Summary of Engineering Report (John Warren).
Annual power consumption = 620,000 KWH
Power plant record: 4.2 acre-ft to 5.3 acre-ft to produce 1000 KW.
Water required = 620,000 x 5.0 acre-ft/ 1000 KW = 3100 acre-ft (annual)
Annual domestic water required = 70 ac-ft
Total Annual Water Required for Ouzinkie = 3170 ac-ft
Water required for annual hydropower at the current level.
Annual hydropower generation = 381,392 KWH (aveage of three years)
Average hydropower consumption = 43.5 Kw
Estimated water waste for waste pipe and spillway losses = 15%
Required water storage =5.0 ac-ft/1000KW x 381,392 KWH/yr x 1.15 = 2193 ac-ft
Coefficient of water available for productive use: C = 2193/3760 = 0.6
Current watershed = 148 ac-ft
Average annual rainfall: 61 in - 84 in
Water storage @ 61" = 2730 acre-ft
Water Storage @ 84" = 3760 acre-ft
Approximately 60% of water falling on the watershed is available at the end of the penstock for productive use.
(C_max = 0.85)
With C =0.6 net water used for productive use after deducting all losses such
as evaporation, ground seepage
Available water for productive use @ 61" = 2730 acre-ft x 0.6 = 1640 ac-ft
Available water for productive use@ 84" = 3760 acre-ft x 0.6 = 2260 ac-ft
Water shortfall = 1530 to 910 ac-ft (48% to 29% of the water demand)
% of diesel power generation over total electrical power demand = 38% (average of three years)
Analysis with Data provided in Ouzinkie Engineering Report by John Warren.
applied to cal power output
Eff increase = 0.05 respective increases for one new turbine (eff(e) +0.05) and two new (eff(e)+0.1)
Eff = 0.7 0.8 (Range of overall efficiency in operation)
Q_max = 9 cfs
watershed = 148 ac-ft (current water storage capacity)
watershed = 183 ac-ft (approximately 25% increase of water storage capacity by raising one foot above the existing spillway)
Net Head = 220 ft w/ New Dam (@ 9cfs)
230 ft w/ New Dam (@ 5cfs)
1 acre = 43560 ft^2
Penstock Dia =17.25 in
1 sq mile = 640 ac
Avg Annual Rainfall =61"
Annual water available = 2730 ac-ft (drainage basin of 0.84 square miles)
Currently, estimated water waste =15%(through waste pipe and spillway losses)
Annual water available = 3380 ac-ft (drainage basin of 1.04 square miles)
(previously estimated 0.84 sq. miles is
re-evaluated to be 1.04)
Estimated water waste in future =5%(through waste pipe and spillway losses)
Correction Factor =0.60 (reasonable range: 50-70%)
