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.
The proposed project is the Triangle Lake hydroelectric project, a new generating plant to be
located on Annette Island. The 4.0 MW project will provide electric power to be transmitted
over the proposed transmission line between Metlakatla and Ketchikan that will be used to offset
diesel generation in Ketchikan and other interconnected communities. The Triangle Lake project
has been studied somewhat in the past and MIC is requesting a grant for Feasibility Analysis and
Conceptual Design.
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.
The proposed Triangle Lake hydroelectric project will be located on the west side of Annette
Island near the route of the proposed Metlakatla – Ketchikan Intertie. The project as presently
envisioned will be comprised of a small embankment dam at the outlet of Triangle Lake, a 1.3
mile long penstock and a powerhouse containing a single horizontal Francis turbine generating
unit with a capacity of 4.0 MW. The Triangle Lake project will provide additional hydroelectric
power to Metlakatla and, with construction of the Metlakatla – Ketchikan Intertie, to the
interconnected electric systems of Ketchikan, Wrangell and Petersburg. MIC will develop and
own the Triangle Lake project.
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 total estimated cost of the Triangle Project through construction is $17,722,000. At this
time, MIC is requesting a grant of $500,000 to conduct the Feasibility Analysis and Conceptual
Design. No other funds are presently available or anticipated for the Triangle Lake project.
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 Triangle Lake hydroelectric project, when combined with the Metlakatla – Ketchikan
Intertie will produce electric power to be used to offset diesel generation in the interconnected
communities of Ketchikan, Wrangell and Petersburg. The project is estimated to be capable of
producing 17,324,000 kWh per year on an average annual basis. This amount of energy would
offset approximately 1,195,000 gallons of diesel fuel per year in Ketchikan, Wrangell and
Petersburg. At $3.10 per gallon (2008 Dollars), the Triangle Lake project would result in
savings of about $4.3 million per year in diesel power production costs. This cost savings is
expected to be shared by electric consumers in Metlakatla, Ketchikan, Wrangell and Petersburg.
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 4 of 17 9/3/2008
The reduction in pollutants emitted from diesel oil combustion will provide benefits to the
general public and the regional environment.
In addition, the project will provide greater flexibility in the operation of the hydroelectric
projects in the interconnected Metlakatla, Ketchikan, Wrangell and Petersburg electric systems
improving total hydroelectric generation overall and improving system reliability.
An important benefit to the Ketchikan area will be that the Triangle Lake project will provide
power from a source that is not dependent on the existing transmission line to Swan Lake. When
the Swan Lake transmission line is unavailable for any reason, Ketchikan is isolated from much
of its hydroelectric generation. The Triangle Lake project will still be available to provide power
from an alternative direction and as such, adds another source of backup generation in the event
of failure of the Swan Lake transmission line.
A further benefit of the Triangle Lake project is that permitting of the Triangle Lake project will
be much easier when compared to other potential hydroelectric developments in southern
Southeast Alaska. Annette Island is a federally recognized Indian Reservation inhabited and
owned in its entirety by the MIC. Accordingly, any upgrade to existing hydroelectric projects or
construction of new hydroelectric projects is not subject to State or Federal regulations.
Therefore, development of projects on Annette Island can be expedited without being subject to
the lengthy Federal Energy Regulatory Commission (FERC) review process that other
hydroelectric projects must undergo.

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.
The hydroelectric energy resources available in Metlakatla at the present time are the 1.0 MW
Chester Lake project and the 3.0 MW Purple Lake project. The two plants are capable of
generating 25,045 MWh per year on average of which about 8,758 MWh is presently estimated to
be surplus to the needs of MP&L. Studies have been conducted in the past that have identified
potential expansions to the existing hydroelectric facilities as well as a new hydroelectric facility
at Triangle Lake. It is estimated that these potential new hydroelectric resources could generate
an additional 20,700 MWh on an average annual basis.
Ketchikan Public Utilities (KPU) owns and operates 11.7 MW of hydroelectric generating
capacity at three separate facilities located relatively close to Ketchikan and 23.0 MW of diesel
generation capacity located in its Bailey Powerplant. The 22.5 MW Swan Lake hydroelectric
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 7 of 17 9/3/2008
project, owned by the Four Dam Pool Power Agency, is also available to KPU and provides a
significant amount of the total power supply requirement in Ketchikan. The total amount of
energy available from the combined hydroelectric resources is about 137,000 MWh on an average
annual basis. To the extent that the combined hydroelectric resources are not sufficient to supply
the entire power supply requirement at any time, diesel generation is used as a supplement.
With the high price of heating oil, there is a significant change to the use of electric space heat by
the residential, commercial and public building customers in Ketchikan. The switch to electric
space heat is causing a noticeable increase in electric loads and as a result, more demand is being
placed on KPU’s diesel generators to meet the growing need for electricity. The present cost of
diesel generation in Ketchikan is estimated to be approximately 23 cents/kWh, a cost that is much
higher than was experienced just a few years ago when fuel prices were lower.
The primary purpose of the Triangle Lake project will be to make additional existing
hydroelectric generation available to serve loads in Ketchikan, Wrangell and Petersburg. KPU
has evaluated several alternative energy resources in recent years including the Whitman Lake
and Mahoney Lake hydroelectric projects, a municipal solid waste to energy project, bio-diesel
generation, and new diesel generators. In order to fully utilize the output of the Triangle Lake
project it will be necessary to complete the proposed Metlakatla – Ketchikan Intertie.
There are many advantages to the Triangle Lake hydroelectric project when compared to the
other alternatives being considered. Principal among the benefits of the project are that no fuel of
any kind is needed and the environmental impacts of are very low compared to building new
generating plants elsewhere. In using hydroelectric energy to supplant diesel generation, the
Intertie project will reduce CO2 and NOx emissions in the region. Further, the reduction of diesel
generation will reduce the amount of diesel fuel that must be barged into Ketchikan thereby
providing an incremental reduction in the probability of fuel spills and other fuel handling
mishaps.
A noticeable benefit of the Triangle Lake project will be that it will provide clean, hydroelectric
energy to Ketchikan, Wrangell and Petersburg that can then be used to offset the use of oil for
space heating. Many residents, schools and businesses in these communities are considering
converting to electric space heat but the high cost of electricity produced with diesel generation is
a deterrent to this transition. Replacing oil heat with electric heat will reduce the amount of
pollutant emissions in the area including CO2, SO2 and NOx.
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 electric system in Metlakatla includes 4.0 MW of hydroelectric capacity and 3.3 MW of
diesel generating capacity. The diesel generator, a 4,500 hp Caterpillar unit, is used primarily as
a backup emergency reserve. A 1.0 MW Battery Energy Storage System (BESS) was installed in
1997 to provide emergency backup power for a limited time as well as balance out frequency and
voltage fluctuations on the MP&L system.
The Chester Lake hydroelectric project was constructed in 1986. It includes a 40 foot high
concrete arch dam, a 20 inch diameter steel penstock approximately 3,521 feet long and a
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 8 of 17 9/3/2008
powerhouse with a single 1,042-kW Pelton turbine generating unit.
The Purple Lake hydroelectric project is comprised of a dam, reservoir, tunnel, penstock and
powerhouse containing three horizontal Francis type turbine generating units, each rated at 1,000-
kW during normal operation. The project was originally built in 1956, however a new control
system was installed in 1997, the generators were all rewound in the 1990’s and the turbine
runners were refinished in the 1990’s as well.
The existing generating units in Ketchikan are shown in the following table:

(1) The rated capacity may exceed the normal maximum operating capacity from the generating units.
(2) Energy generation capability for hydroelectric resources is based on average water conditions and load levels
similar to those experienced in 2000. Hydroelectric energy generation varies from year to year.
(3) Energy generation for the KPU-owned hydroelectric resources is not differentiated by unit.
(4) Diesel generators are shown as capacity resources only, although they are used to provide energy supplemental to
that provided by the hydroelectric facilities. At a 70% annual plant factor, the annual energy generation capability
of the four diesel units is 141,040 MWh.
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.
At the present time, MP&L uses its hydroelectric generating resources, the Chester Lake and
Purple Lake projects, to meet its own load. Additional energy generation capability, surplus to
the needs of MP&L, exists at these plants.
In Ketchikan, KPU fully utilizes the generating capability of its City-owned hydroelectric
generating facilities. Power is then purchased from the Swan Lake project to meet the remaining
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 9 of 17 9/3/2008
energy requirement. At certain times, the generating capability of the combined hydroelectric
facilities is insufficient to supply the total load in Ketchikan. This hydroelectric shortage can
actually last for an extended time if local precipitation is low. During the times when
hydroelectric energy is insufficient, diesel generation is used to meet the remaining load
requirement.
With the Triangle Lake project, additional hydroelectric energy generation will be available to
KPU to supply loads and avoid all or a portion of the amount of diesel generation that would be
needed otherwise. Another advantage of the project will be that the hydroelectric facilities of the
Metlakatla, Ketchikan, Petersburg and Wrangell electric utilities can be operated in a coordinated
fashion so as to maximize the capability of all the facilities. This operating improvement is
typical of larger systems where individual generating units can be operated within their most
efficient ranges and the various reservoirs can be operated most effectively.
With the Metlakatla-Ketchikan Intertie and the Swan-Tyee Intertie, currently under construction,
a significantly larger southern Southeast Alaska interconnected electric system will exist. The
various hydroelectric facilities within this four community system can be operated on an
integrated basis for overall maximum efficiency. Reliability in the four communities will be
improved through additional backup options and maintenance on various generating units and
transmission lines can be effectively coordinated to reduce outage impacts to electric consumers.
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
In 2007, the total energy sales in Metlakatla were approximately 14,500 MWh of which 6,180
MWh, or 43%, was to residential customers. As previously indicated, the total annual
hydroelectric energy generation capability of the existing hydroelectric resources in Metlakatla is
about 25,000 MWh.
Total energy sales in Ketchikan in 2007 were about 155,800 MWh and were about 60,000 MWh
in Petersburg and Wrangell combined. Energy sales in all three of these communities are
expected to increase noticeably in the immediate future as various residential, public authority
and commercial customers switch to electric heat in response to continuing high oil prices. The
Triangle Lake project will contribute to lower power costs in Ketchikan, Petersburg and
Wrangell. Municipal electric utilities set rates based on their costs. Lower power costs will mean
lower electric rates, a direct benefit to electric consumers.
It is expected that the benefits of the Triangle Lake project in offsetting diesel generation costs
will be jointly shared by Ketchikan, Petersburg, Wrangell and Metlakatla. In Ketchikan,
Petersburg and Wrangell, the benefits will mean lower electric rates to consumers. In Metlakatla,
the benefits can also mean lower electric rates to electric consumers. The benefits in Metlakatla
can also be utilized in paying the costs of repairs, replacements and improvements to MP&L’s
electric system.

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
The proposed Triangle Lake hydroelectric project will be located on the west side of Annette
Island near the route of the proposed Metlakatla – Ketchikan Intertie. The project as presently
envisioned will be comprised of a small embankment dam at the outlet of Triangle Lake, a 1.3
mile long penstock and a powerhouse containing a single horizontal Francis turbine generating
unit. The dam would raise the normal maximum pool elevation from 383 feet to 400 feet, msl,
and allowing for up to 7 percent losses a 4.0 MW turbine generating unit could be installed.
Access to the proposed powerhouse site would be via a new 2.7 mile extension from a logging
road that connects the Base Camp with the Dash Point Road staging area. An additional 1.3 mile
access road would be needed along the penstock route to the dam site. The transmission line
from the powerhouse switching station would be about 2.7 miles long and would operate at 34.5-
kV.
For purposes of preparing a preliminary cost estimate, it is assumed that the dam would be
constructed at El. 395 and would be 300 feet long at its crest and 50 feet wide at its base. Crest
width would be 12 feet with rock embankment slopes of approximately 34 degrees. The dam
would have an impervious clay core and a 50 foot wide spillway would be excavated from one of
the abutments and would have an un-gated concrete crest.
The drainage area of the project is estimated to be 5.5 square miles and the inflow to Triangle
Lake is estimated at 77.9 cfs, which corresponds to an annual average runoff of 193 inches over
the watershed. The site is assumed to have no in-stream flow downstream of the embankment
dam. With an average net head of 370 feet and an allowance of 5% for outages, the estimated
annual generation would be 17,324 MWh from the 4.0MW generating unit.
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 Triangle Lake hydroelectric project will be located entirely on Annette Island and as such,
MIC will have authority over all aspects related to land ownership and site approval. MIC has
studied the project in the past and will work with its consultants, engineers and advisors to
determine its most optimal configuration.
4.3.3 Permits
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 11 of 17 9/3/2008
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
A significant benefit of the Triangle Lake project is that permitting will be much easier when
compared to other potential hydroelectric developments in southern Southeast Alaska. Annette
Island is a federally recognized Indian Reservation inhabited and owned in its entirety by the
MIC. Accordingly, any upgrade to existing hydroelectric projects or construction of new
hydroelectric projects is not subject to State or Federal regulations. Therefore, development of
projects on Annette Island can be expedited without being subject to the lengthy Federal Energy
Regulatory Commission (FERC) review process that other hydroelectric projects must undergo.
MIC will have authority over all other necessary permits and approvals
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
It is not expected that these environmental issues will be significant.
4.4 Proposed New System Costs (Total Estimated Costs and proposed Revenues)
The level of cost information provided will vary according to the phase of funding requested and
any previous work the applicant may have done on the project. Applicants must reference the
source of their cost data. For example: Applicants Records or Analysis, Industry Standards,
Consultant or Manufacturer’s estimates.

Ketchikan Public Utilities (KPU), Wrangell and Petersburg. The power sales price will be
negotiated between MIC and these utilities and is expected to be reflective of the cost of power
available to KPU, Wrangell and Petersburg from other alternatives. At the present time, KPU,
Petersburg and Wrangell pay 6.8 cents per kWh for Swan Lake and Tyee Lake power that is
purchased from the Four Dam Pool. Other new hydroelectric alternatives for KPU are estimated
to have a cost of power in the range of 7.0 cents per kWh and the cost of diesel generation for
KPU is about 23 cents per kWh when diesel fuel is at $3.10 per gallon. It is estimated that the
sales price of power from the Triangle Lake project would be in the range of 4.5 to 8.0 cents per
kWh.
4.4.4 Cost Worksheet
Complete the cost worksheet form which provides summary information that will be considered
in evaluating the project.
See attached application worksheet.
It is important to note that in the estimation of benefits for the Triangle Lake hydroelectric project
only the net fuel and incremental diesel O&M savings have been included. Additional “capacity”
benefits will be realized by Ketchikan in that the Intertie will provide additional reserve benefits
to KPU. The value of this capacity benefit has not been estimated at this time.
Fuel savings have been estimated assuming that the full amount of generation available at the
project will be sold to KPU, Petersburg and Wrangell to offset diesel generation. Energy loads in
Ketchikan, Petersburg and Wrangell are expected to increase significantly as more emphasis is
placed on electric space heat in these communities.
The calculation of the Benefit Cost ratio shown in the Cost worksheet is based on the net present
value of estimated net benefits over a 30 year project life assuming a 5.5% discount rate.

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 Triangle Lake hydroelectric project will be operated by MP&L in coordination with KPU
and the Southeast Alaska Power Agency (SEAPA will be the successor agency to the Four Dam
Pool Power Agency as of approximately January 1, 2009). Agreements will be established to
assure effective maintenance and operating standards are in place and administered. Further,
standard utility operating procedures to assure safe and reliable operation will be identified in
contracts between MP&L, KPU and SEAPA and will be adhered to. MP&L, KPU and SEAPA
currently own, operate hydroelectric facilities similar to the Triangle Lake project and are very
familiar with what will be needed to assure a long, useful life for the project.
4.4.6 Analysis and Recommendations
Provide information about the economic analysis and the proposed project. Discuss your
recommendation for additional project development work.
A detailed analysis of the benefits of the Triangle Lake project has been developed assuming full
utilization of the generating capability of the project to offset diesel generation. The analysis
estimates the amount of diesel fuel offset on a yearly basis assuming a fuel use rate of 14.5 kWh
per gallon. Based on an assumed present cost of diesel fuel of $3.10 per gallon and assumed
escalation in diesel fuel of 3% per year, the annual savings in fuel costs is estimated. The
incremental savings in diesel generator O&M is also estimated based on an O&M cost of 1.5
cents per kWh.
The estimated annual savings in fuel costs are reduced by the O&M costs for the Triangle Lake
project.
The total net present value savings of the estimated net benefits of the Intertie over a 30-year
analysis period has been calculated assuming a 5.5% discount rate. The net present value savings
based on this analysis is $70,192,000 resulting in a benefit to cost ratio of 3.96 for the project cost
of $17,722,000.

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
As indicated in Section 4.4.6, the net present value savings of the net benefit of the Triangle Lake
hydroelectric project is $70,192,000 over the life of the project (30 years for this analysis). This
benefit will be derived almost entirely from the savings in fuel costs for diesel generation.
Other economic benefits that have not been evaluated yet include the capacity benefit that KPU
will realize with the Triangle Lake project since the project will be available to serve loads in
Ketchikan even when the Swan Lake project or the Swan Lake transmission line are unavailable.
It is also important to note that with the Triangle Lake project, KPU, Petersburg and Wrangell
will be able to provide lower power costs in their communities than could be realized with diesel
generation. These lower power costs will then help local residents, public facilities and
businesses realize greater savings if they choose to transition from oil to electric space heat. The
lower electric rates will consequently serve as an additional incentive to convert to electric heat.
The amount that local consumers would save in heating bills by converting to electric heat has not
been evaluated as part of this application.
Other benefits of the Triangle Lake hydroelectric project include:
More efficient use of the area’s hydroelectric generating resources
Relatively minor negative environmental impacts related to installation and operation of
the project
Reduced oil consumption in the area
Reduced air pollution from burning of oil
Incrementally lower risks of fuel handling mishaps
Incrementally lower need for fuel deliveries in and transport through Southeast Alaska
Lower greenhouse gas emissions
Greater electric system reliability
More encouragement to convert to electric space heat in the area
Additional construction jobs in the Metlakatla area
Creation of additional power plant operator jobs in the Metlakatla area
