The Ruby Tribal Council is proposing to partner with the Alaska Center for Energy and Power (ACEP) to
perform a geothermal Resource Assessment of the Horner and Melozi Hot Springs geothermal resources
for potential power generation and space heating for the City of Ruby and the neighboring areas. The
project includes using available thermal infrared images to generate a land surface temperature and
emissivity map of the study area; using available optical data to create a landcover classification map;
acquiring and processing hundreds of airborne thermal infrared images; collecting in-situ field data for
geometric rectification of airborne images, driving the remote sensing data analysis, and validating
analysis results; conducting economic analysis of the area’s energy resource potential; and community
outreach.

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 future energy needs of City of Ruby are well recognized. However, the three alternate energy options
proposed in energy inventory prepared by AEA in January 2009, each have huge challenges associated
with them. For example, the report identifies biomass (wood) and wind energy as potential alternative
sources, but also clearly cites the high capital expense and unproven technologies in the case of wood-
fired Combined Heat and Power (CHP) systems.
Our proposed workplan outlined in this proposal will, for the first time, result in the systematic evaluation
of the geothermal potential of the study area using state-of-the-art remote sensing based exploration
techniques along with an economic feasibility analysis. This non-existent baseline information is critical
in long term decision making for energy production in the area.
Geothermal energy has the advantage of being able to provide baseload, dispatchable power with
availability approaching that of diesel generators (>99% is common). For communities with potential
access to a known geothermal resource within a reasonable distance, it should be considered as preferable
to other, less-dispatchable renewable sources of energy, provided that the economics are also compelling.
In addition to supplying electric power, geothermal energy can also provide space heating and cooling if
the resource is located close enough to the load. In this case, we do not expect it will be economic to
develop geothermal resources for space heating or cooling applications for Ruby.
This project also has the added benefit that it will add to our overall understanding of geothermal
resources within the Central Alaskan Hot Springs Belt. There are several other communities throughout
the region there are near hot springs, and the resource at Chena Hot Springs has been developed to meet
electric power, heating, and cooling needs at the site. These systems are not well understood, although
they are generally located near the margins of intrusive granitic pluton bodies. The systems near Ruby are
no exception. Adding to the understanding of how deep fluids circulate, and overall thermal pass of the
system, will help to determine whether these systems could be developed for beneficial use.
Finally, the techniques proposed through this project will be transferable to other parts of the state that
have low and moderate temperature geothermal resources. The ground surveys outlined in this proposal
will help to verify this technique, and could save millions of dollars in future geothermal exploration
efforts around the state. The University of Alaska has recently received a $4.5 million grant from the
Department of Energy to better develop these techniques, which were first demonstrated in Alaska at
Chena Hot Springs.
2.6 PROJECT BUDGET OVERVIEW

SECTION 3 – PROJECT MANAGEMENT PLAN
Describe who will be responsible for managing the project and provide a plan for successfully
completing the project within the scope, schedule and budget proposed in the application.
3.1 Project Manager
Tell us who will be managing the project for the Grantee and include a resume and references
for the manager(s). If the applicant does not have a project manager indicate how you intend to
solicit project management support. If the applicant expects project management assistance
from AEA or another government entity, state that in this section.
The PI for the Ruby Tribal Council is Pat Sweetsir, Tribal Administrator, who will oversee the project,
perform administrative duties, and assist UAF personnel with the field work. Ruby Tribal Council has
identified geothermal assessments of the two project locations as a priority for the community’s decision-
making process on energy issues.
The PI for UAF is ACEP Director Gwen Holdmann, who previously served as PI for the geothermal
exploration and development project at Chena Hot Springs Resort. The Melozi and Horner geothermal
resources are both considered to be part of the Central Alaska Hot Springs Belt and are expected to
contain similar hydrothermal systems. Holdmann is also the PI for a geothermal exploration project in the
Pilgrim Hot Springs Area, which is now recommended for funding by the Department of Energy (DoE).
Project Co-PI Dr. Anupma Prakash is a Professor at the Geophysical Institute, University of Alaska
Fairbanks. Her research expertise is in using remote sensing and geographic information systems
techniques for characterizing land surface composition and change in high latitude regions, and she has
worked extensively with thermal infrared data (including on the Chena Hot Springs project). In addition,
Ross Coen, Rural Energy Specialist at ACEP, will serve as the community outreach lead for the project
and will also assist the PIs with project management tasks, including preparation of quarterly and final
project reports.
3.2 Project Schedule
Include a schedule for the proposed work that will be funded by this grant. (You may include a
chart or table attachment with a summary of dates below.)
Tasks to meet our objectives along with technical details and timeline for these tasks are outlined below.
This exploration project is expected to take one year to complete.
Task 1 (July 2010) – Use available thermal infrared images from moderate resolution Earth Observing
Satellites, such as Landsat and ASTER to generate a land surface temperature and emissivity map of the
study area at a regional 1:50,000 scale. (Note: Archived Landsat data are available at no cost from US
Geological Survey. Dr. Prakash is an approved NASA science data user and will receive archived and
potentially new ASTER data over the study area at no additional cost to the project).
Task 2 (July through August 2010) – Use available optical data from archived Landsat images and
potentially new ASTER images, and available archived CIR air photos to create a landcover
classification map at a regional 1:50,000 scale and in parts at 1:10,000 scale. This landcover map will
serve as the base map to understand the landuse practice in the study area. The investigators will also use
old U2 color infrared airborne images from the late 70s and available recent optical images over the study
area (Figure 1) to characterize the landscape at a better spatial scale.
Task 3 (July through September 2010) – Acquire airborne thermal infrared images in summer and early
fall at local reconnaissance and detail survey scale. The local reconnaissance scale survey will be carried
out to provide thermal infrared images at approximately 4m spatial resolution and will cover an area of
about 3km*5km centered around the hot spring. The detail survey will be carried out by flying a lower
height of about 750m to provide thermal infrared images at approximately 1m spatial resolution.

Acquiring the data at two different times will help to reduce uncertainties in analysis introduced due to
seasonal effects. The thermal infrared data will be acquired using a FLIR® Systems Automation Series
ThermaCam A320 mounted on a Cessna Skywagon 185, flown by Tom George of Terra Terpret, Inc.
Along with the thermal images, a near infrared camera will be mounted on the plane to acquire concurrent
multispectral images that will help to further characterize the terrain and the vegetation cover and help
with thermal image interpretation. A similar setup used in for a thermal survey over Chena Hot Springs,
Alaska in 2004-2005 gave excellent results (Figure 2).
Figure 1. Airborne optical image of the Melozi Hot Springs area.
Task 4 (July through September 2010) – Field data acquisition. Concurrent to the airborne campaign, in-
situ field data will be collected for assisting in geometric rectification of airborne image, driving the
remote sensing data analysis and for validation of analysis results. Contingent on local field conditions
and logistical support available during field season, data collection activities will include, but will not be
limited to, measuring ground control points using high-precision global positioning systems (GPS);
measuring contact temperatures at selected locations using thermal probes; measurement of atmospheric
parameters such as air temperature humidity etc. for atmospheric correction; field photos for land cover
validation; and water sampling at selected locations.

and are centered on where the greatest surface expression of heat is visible in the thermal
infrared images. Right: Thermal infrared image of approximately corresponding area. The roofs
of buildings and snowfall reflect sunlight in the 15-20C range. Differing vegetation shows
different temperatures due to the difference in emissivity of various plants and the bare ground.
Task 5 (July 2010 through May 2011) Process and analyze airborne thermal infrared images. This task
will be the most time intensive part of the project. The airborne campaign will result in acquisition of
hundreds of thermal infrared images, with each image frame containing 320 x 240 pixels. The individual
image frames will be georectified and mosaiced to create a near seamless thermal mosaic of the study
area. Again, the mosaic will be created for both the local reconnaissance scale and the detail survey scale
images. Pixel integrated temperatures over a broad 7.5-13 m range (spectral range of the thermal
instrument) will be calculated for each image pixel, after correcting for atmospheric conditions (humidity
and temperature) and range (distance to the target). A similar mosaic will be created for the airborne
optical images to facilitate direct comparison of thermal data with the optical data. The image mosaics
from spring will be compared with image mosaics from late summer/early Fall to account for seasonal
affects in the data. Thermally anomalous pixels will be identified using statistical analysis and
thresholding to separate anomalous pixels from the background pixels. For each thermally anomalous
pixel the relative heat loss in watts will be calculated after correcting for the background temperature,
measuring only flux beyond the natural radiative heat of the Earth and Sun. An error analysis will be
carried out to account for errors introduced by the instrument, atmosphere, aircraft orientation, and the
general terrain.
Task 6 (June 2011) – Economic Feasibility Study and Final Reporting. Using the results of Tasks 1-5, we
will complete an economic feasibility assessment of potential project configurations to determine optimal
next steps. This work will be completed by economist Markus Mager of the Alaska Center for Energy and
Power. If possible, this task will include a comparison with other renewable and alternative energy
options for Ruby. The final project report will be available in June 2011 at the completion of the one-year
project.
Task 7 (Ongoing for project duration) – Community Outreach. Community meetings will be held before
the resource assessment begins to inform residents of the workplan, and following the completion of work
to present project results and distribute the final report. This task also includes regular communication

between Ross Coen and stakeholders in Ruby, as well as those throughout the TCC region who are
interested in energy research.
3.3 Project Milestones
Define key tasks and decision points in your project and a schedule for achieving them. The
Milestones must also be included on your budget worksheet to demonstrate how you propose to
manage the project cash flow. (See Section 2 of the RFA or the Budget Form.)
Project milestones include completion of each of the outlined tasks of the project during the planned
timeline. An interim report will be compiled following the summer/fall 2010 field campaign. The final
project report, including economic analysis, will be completed in June 2011. A separate technical paper
presenting the technical components of this study, analyses of the results, and discussions and future
recommendations will be compiled separately at the conclusion of the project.
3.4 Project Resources
Describe the personnel, contractors, equipment, and services you will use to accomplish the
project. Include any partnerships or commitments with other entities you have or anticipate will
be needed to complete your project. Describe any existing contracts and the selection process
you may use for major equipment purchases or contracts. Include brief resumes and references
for known, key personnel, contractors, and suppliers as an attachment to your application.
Project personnel: In addition to the project managers listed in section 3.1, the program will support one
postdoctoral candidate and one undergraduate student who will carry out the bulk of the image processing
and data analysis task under the supervision of Co-PI Prakash.
Project equipment: Major equipment (e.g., FLIR automation series camera) required for this project is
already available with the PIs from the University of Alaska. The multispectral camera available with the
team will require modifications, including addition of special filters to work in the near infrared regions.
Nominal charges required for such adaptations have been included in the budget.
3.5 Project Communications
Discuss how you plan to monitor the project and keep the Authority informed of the status.
Quarterly reports will be prepared and submitted to the Alaska Energy Authority. An interim report will
be completed following the summer/fall 2010 field campaign, and a final report will be completed by
June 2011.
3.6 Project Risk
Discuss potential problems and how you would address them.
The project involves standard assessment and exploration techniques minimizing any perceived risk.
Project delays may occur related to weather conditions during field activities including the aerial infrared
surveys. Scheduling field activities during the summer months will mitigate most expected problems
related to field work.

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.
Study Area and its Energy Needs: Ruby is a community of 167 people, about four-fifths Alaska Native,
located on the south bank of the Yukon River in central Alaska, approximately 230 air miles west of
Fairbanks. The energy needs of the city are currently met by a power plant that is operated by the City.
This plant includes three Caterpillar generator sets (125 kW, 225 kW, 250 kW) the first two of which are
more than 15 years old and have undergone multiple rebuilds, the last installed in 2006 and in good
condition. The current average electrical load in summer is 55 kW and in winter is 85 kW.
On behalf of the Alaska Energy Authority (AEA), CRW Engineering Group completed a Final Conceptual
Design Report (June 2009) for a new building to house the power generation infrastructure and to replace
the two outdated gen-sets. The CRW report projects that by 2019 the load will increase by about 35 kW.
This increase will be due to increased population and the completion of water/sewer improvements. In
assessing alternative energy options for Ruby, the CRW report states: “Rising fuel costs and mounting
regulatory concern over fuel spills and power plant emissions warrant a close evaluation of potential
alternative energy sources. With proper planning, design, and management, today’s alternative energy
technologies could reduce rural Alaska’s dependence upon fossil fuels.”
One way to proactively address the projected energy needs of the City, while keeping a low dependency
on fossil fuels in the future, is by evaluating local alternative energy resources. Geothermal energy is one
such alternative.
Geothermal Energy as an Alternate Option: The City of Ruby is strategically located in the proximity of
two known hot springs. Horner Hot Springs is on the Yukon about 23 miles upstream from the village.
Melozi Hot Springs is located on the Melozitna River, a tributary of the Yukon, approximately 36 miles
northeast of Ruby. Such proximity raises the likelihood of the area having the potential for geothermal
energy. However, to-date, no systematic geothermal resource assessment, feasibility study, or cost-benefit
analysis has been carried out for the area. This project aims at carrying out such as assessment for the
study area using satellite-based, airborne and ground based exploration techniques. The feasibility study
(technical, resource, and economic) of the proposal will be led by the Alaska Center for Energy and Power
(ACEP) and carried out in collaboration with the Geophysical Institute (GI) at the University of Alaska
Fairbanks. ACEP and GI will work in close collaboration with the City of Ruby in this larger geothermal
project. We anticipate that results from this project will serve to support strategic decision making for
meeting the long term energy needs for the City of Ruby.
Remote Predictive Resource Assessment: For any geothermal development in this area, a systematic
survey and analysis on the extent, nature, magnitude of the thermal anomaly, and a quantitative estimate of
the heat flux beyond the natural radiative heat of the Earth and Sun is required and is particularly useful in
determining the extent to which the resource can be exploited for sustainable power generation or direct

Grant Application Round 3

use. Satellite remote sensing and specialized airborne surveys carried out using thermal infrared sensors
(sensors operating in the thermal infrared portion of the spectrum, and therefore sensitive to land surface
temperatures) are very useful in such mapping and quantitative temperature and flux estimations. The
work will be complimented by limited field based surveys for new data collection and validation of remote
sensing observations. The technical details of the remote sensing and field based resource exploration
proposed for this study are elaborated in section 3.2 (project tasks and timeline) of this proposal.
As with other areas in the vast wilderness of Alaska, this study area has accessibility issues. For example,
the Melozitna River features a stretch of impassable rapids a few miles upstream from its confluence with
the Yukon. Reaching the hot springs by boat requires a portage around the rapids. Remote sensing
techniques, by virtue of being a non-contact method of exploration, are a practical solution to these
hindrances. The proposed airborne thermal infrared imaging survey will provide a synoptic overview of
the area without the logistical complexities of trying to map a large area systematically by foot. The
technology proposed for this project has already been tried in the Chena Hot Springs Geothermal Area,
Alaska, by the project PIs and yielded very promising results. The proposed technique is also a very low-
cost exploration technique, which has the added advantage of very low risk and potentially a high
benefit/cost ratio for the City of Ruby.
Economic Feasibility Assessment: The overarching goal of this project is to obtain the minimal
information needed to make an informed decision as to whether a sustainable geothermal project could be
developed for Ruby, and then complete an economic assessment of various potential project
configurations. It is generally understood that in order to determine the size of project a resource is capable
of sustaining long-term, three critical pieces of information are needed: 1) total heat flow to the surface, 2)
temperature at depth, and 3) depth to access the resource. The project team will determine these values by
using a combination of aerial, satellite-based, and ground based surveys (see section 3.2). This information
will then be integrated with existing and projected heat and electric power load data for Ruby, as well as
known cost of development from other sites (power plant and transmission). It will be assumed that a
Binary Organic Rankine cycle turbine will be used for power generation, similar to the turbine installed at
Chena Hot Springs near Fairbanks in 2006.
Outreach to Community: This project will make full use of the existing partnership between the Alaska
Center for Energy and Power and Tanana Chiefs Conference (TCC) in performing community outreach.
TCC is a non-profit Native consortium of 42 villages in the Interior of the state, including Ruby and the
region surrounding both Melozi and Horner hot springs. The ACEP-TCC partnership was formed in early
2009 to combine the community organizing and rural service capacity of TCC with the technical and
engineering expertise of ACEP in order to facilitate energy research and development in the region. Ross
Coen, whose position of Rural Energy Specialist is part of this joint partnership, will oversee community
relations and outreach with the residents of Ruby. Two community meetings will be held—one prior to the
start of the assessment program to inform the community of the workplan, and one following completion
of the project when results and final reporting will be shared. In addition, Coen will maintain regular
contact with the City of Ruby, Ruby Tribal Council, Dineega Village Corporation, and Doyon, Ltd. to
keep them apprised of the project’s progress. Coen will also maintain contact with the Yukon River Inter-
Tribal Watershed Council, a coalition of 66 river villages that has worked on energy issues in the region,
including the hydrokinetic test project currently taking place in Ruby.
As a resource assessment, the objective of this project is to determine the potential extent and amount of
the energy resource that is available. Specifically, the Ruby/Melozi/Horner geothermal assessment project
is designed to provide baseline information for an area that is not well studied for its geothermal potential
and economic analysis for future development of the resource for power generation. Geothermal resource
development has been demonstrated at other sites in Alaska (Chena Hot Springs), and new technology has
resulted in power production from lower temperature resources such as could potentially exist in the study
area. Unlike most renewable energy systems, geothermal energy can supply baseload power and therefore
is available 24 hours a day and 365 days a year. In addition to power generation, it is also a viable
resource to replace conventional fossil fuel for space heating.

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.
There is no existing energy system at Melozi and Horner Hot Springs. The community in the neighboring
City of Ruby uses diesel gen-sets for primary power generation and fuel oil for heating.
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.
Diesel fuel in the City power plant is the primary energy resource for electricity production in Ruby.
According to Power Cost Equalization data and an inventory prepared by the Alaska Energy Authority in
January 2009, the diesel consumption in 2008 was 26,400 gallons. Space heating needs in the community
are met primarily by heating oil, with wood as an alternate resource. Apart from a hydrokinetic test project
being conducted the last two summers in Ruby (which, as a test project, presently generates a negligible
amount of power in summer only), there are no community-wide alternative or renewable energy sources
being used. This proposal is for a resource assessment only, and thus will have no effect on existing
energy infrastructure and resources.
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
If developed, the existing energy market for the geothermal power plant would be the community of Ruby.
(There have been tourist lodges at both locations—one at Horner in the 1920s, and one at Melozi that was
in operation as late as the 1980s—and it remains possible that energy development at either location might
again lead to tourism.) Average electric use in Ruby is 55 kW in summer and 85 kW in winter, with peak
loads in the range of 108 kW. The proposed new power plant described in Section 2.2 is being designed
with an estimated increase in electric use of 35 kW by 2019. This proposal will result in a resource
assessment of Melozi and Horner hot springs—not actual development of the energy resource—thus its
impact on energy customers will be zero. Any potential future development, however, will have to be
integrated with the existing energy infrastructure. This proposal seeks to provide baseline information on a
potential energy resource that will lead to informed decision-making.
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:

This proposal is for an exploration and assessment study only and does not propose to install a system.
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.
Melozi Hot Springs is located on federal land managed by the Bureau of Land Management. Horner Hot
Springs is located on land owned Doyon, Ltd., the for-profit Native regional corporation in Interior
Alaska. Although the project PIs have not reached formal agreements with either entity, the proposal calls
only for remote-sensing data collection and non-invasive, non-disruptive field work, and the PIs do not
anticipate land ownership issues to present a problem in this feasibility phase. Ruby Tribal Council, the
primary applicant, intends to conduct this project in accordance with the same respect for land use and
ownership it applies to its own business operations. The respective land owners will be consulted and will
be kept informed of the project and its progress throughout the study.
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
Beyond any applicable permits for actual site access, we do not anticipate permits required for the field
work. No invasive work that might disrupt the locations will be completed as part of this project. A
complete field risk assessment will be completed through the University of Alaska as per standard
protocol, and any necessary training will be completed.
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

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
The future energy needs of City of Ruby are well recognized. However, the three alternate energy options
proposed in energy inventory prepared by AEA in January 2009, each have huge challenges associated
with them. For example, the report identifies biomass (wood) and wind energy as potential alternative
sources, but also clearly cites the high capital expense and unproven technologies in the case of wood-fired
Combined Heat and Power (CHP) systems.
Our proposed workplan outlined in this proposal will, for the first time, result in the systematic evaluation
of the geothermal potential of the study area using state-of-the-art remote sensing based exploration
techniques along with an economic feasibility analysis. This non-existent baseline information is critical in
long term decision making for energy production in the area.
Geothermal energy has the advantage of being able to provide baseload, dispatchable power with
availability approaching that of diesel generators (>99% is common). For communities with potential
access to a known geothermal resource within a reasonable distance, it should be considered as preferable
to other, less-dispatchable renewable sources of energy, provided that the economics are also compelling.
In addition to supplying electric power, geothermal energy can also provide space heating and cooling if
the resource is located close enough to the load. In this case, we do not expect it will be economic to
develop geothermal resources for space heating or cooling applications for Ruby.
This project also has the added benefit that it will add to our overall understanding of geothermal resources
within the Central Alaskan Hot Springs Belt. There are several other communities throughout the region
there are near hot springs, and the resource at Chena Hot Springs has been developed to meet electric
power, heating, and cooling needs at the site. These systems are not well understood, although they are
generally located near the margins of intrusive granitic pluton bodies. The systems near Ruby are no
exception. Adding to the understanding of how deep fluids circulate, and overall thermal pass of the
system, will help to determine whether these systems could be developed for beneficial use.
Finally, the techniques proposed through this project will be transferable to other parts of the state that
have low and moderate temperature geothermal resources. The ground surveys outlined in this proposal
will help to verify this technique, and could save millions of dollars in future geothermal exploration
efforts around the state. The University of Alaska has recently received a $4.5 million dollar grant from
the Department of Energy to better develop these techniques, which were first demonstrated in Alaska at
Chena Hot Springs.
SECTION 6– SUSTAINABILITY

SECTION 7 – READINESS & COMPLIANCE WITH OTHER GRANTS
Discuss what you have done to prepare for this award and how quickly you intend to proceed
with work once your grant is approved.
Tell us what you may have already accomplished on the project to date and identify other grants
that may have been previously awarded for this project and the degree you have been able to
meet the requirements of previous grants.
The scope of this proposal includes field work, mapping, and data analysis for which the project staff has
extensive experience and is able to mobilize quickly. The proposal includes staff time for senior personnel
and postdoctoral/student personnel, all of whom are positioned to incorporate this project into their 2010-
2011 workplan. It is expected that upon grant approval in summer 2010, the field work can begin
immediately.
The University of Alaska has recently received a $4.5 million grant from the Department of Energy (DoE)
to better develop geothermal assessment techniques, which were first demonstrated in Alaska at Chena
Hot Springs. This proposal represents an application of ground surveys that will help to verify those
techniques. The DoE award demonstrates the project team’s readiness and qualifications for the work
outlined in this proposal.
SECTION 8– LOCAL SUPORT
Discuss what local support or possible opposition there may be regarding your project. Include
letters of support from the community that would benefit from this project.
This proposal has the full support of the Ruby Tribal Council. It is also supported by Tanana Chiefs
Conference (TCC), the Native non-profit consortium of forty-two villages in Interior Alaska, the
Executive Board of which has made geothermal resource assessment a priority in the region. Earlier this
year TCC entered into a formal partnership with the Alaska Center for Center and Power (ACEP), of
which PI Gwen Holdmann is the director, on rural energy development. This proposal represents a joint
effort on the part of Ruby Tribal Council and the TCC-ACEP partnership.
SECTION 9 – GRANT BUDGET
Tell us how much you want in grant funds Include any investments to date and funding sources,
how much is being requested in grant funds, and additional investments you will make as an
applicant.
