2.4 Project Description
Provide a brief, one-paragraph description of the proposed heat project.
This project will design and construct a diesel heat recovery system between the AVEC powerplant and the Yakutat Community Health Center (YCHC). The distribution loop will be buried and consist
of preinsulated 3” PEX, tied into the YCHC health center heating system. The proposed project is anticipated to reduce diesel fuel consumption of the Yakutat Community Health Center by 18,400
gallons annually as estimated by the ANTHC Heat Recovery Feasibility Study.
2.5 Scope of Work
Provide a short narrative for the 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.
The scope of work for this project includes completing a cooperative project agreement (CPA)
between the Yakutat Tlingit Tribe (YTT) and the Alaska Native Tribal Health Consortium (ANTHC) such that ANTHC is empowered to oversee all design, construction, and grants management tasks associated with this project.
Once this CPA is established, the next major tasks will be to complete Phase III engineering design and permitting activities. These activities will include the design and routing of the distribution piping,
the tie into the generator cooling system at the AVEC power plant, and the tie-in to the existing diesel-fired heating system at the YCHC. Selection of an engineering firm to complete the project will be
performed via a previously completed term contract by ANTHC to pre-qualify engineering services
from a variety of firms, including experience and qualifications to design rural diesel heat recovery systems.
Once 100% of the requisite design documents have been completed, the project personnel will then conduct a Request for Proposal (RFP) for construction services to complete Phase IV construction
of the project, including procurement, shipping, and assembly of all materials.
Procurement will immediately follow the successful selection of a qualified contractor. Procured
materials will include pre-insulated HDPE piping as well as schedule 40 steel and copper piping for
intertie to the power plant and health center facilities, respectively. Additionally, heat exchangers, Grundfos Magna pumps, T775 controllers, and other project components will be procured for
shipment via barge to Yakutat.
Following procurement, field construction activities will consist of three primary undertakings. First,
buried HDPE pre-insulated piping must be installed in a loop between the health center and the AVEC power plant. This will be completed using horizontal drilling and will require one crossing of a DOT-maintained road. [VACJ1] [GD2] Second will be the installation of mechanical, electrical, and
control systems within the YCHC. Third, these systems and the accompanying controls/programming must be tied into the existing heat recovery system and generator cooling
system at the AVEC power plant.
The final project-specific task will involve system commissioning, startup activities, and the training
of facility operators. This task will be conducted by ANTHC Tribal Utility Support Engineers specially
trained in operator training and controls. The facility operations team at the YCHC and AVEC power plant operators will be trained in controls and system operations relevant to their positions. With this
knowledge in place, the system will be tuned for maximum operational efficiency. Once all

inclusive of an additional project to replace the existing Yakutat system serving the School and Public Works facility, is attached to this application in Appendix A. Will has extensive experience designing and overseeing the construction of multiple Heat Recovery projects throughout rural Alaska. Mr.
Fraser produced an Engineering Memo defining the scope of this project as a component of the overall project, which is provided in Appendix A. The detailed estimate of costs is provided in Appendix A3 and is based upon the engineer's Opinion of Probably Cost.
3.3 Project Communications
3.3.1 Project Progress Reporting
Describe how you plan to monitor the progress of the project and keep AEA informed of the status. Who will be responsible for tracking the progress? What tools and methods will be used to track
progress?
The YTT will enter into a Cooperative Project Agreement (CPA) with ANTHC, which will authorize
Consortium personnel to provide project and grant management services for the proposed heat recovery project.
The Grants Management and Compliance Department, overseen by the Grants and Other Restricted Revenue Manager, is staffed to provide comprehensive grants administration and assistance to
ANTHC projects, including those the organization is contracted to manage. The department
manages well over a hundred million dollars in grant-funded projects on an annual basis. ANTHC's current portfolio includes grants from a variety of federal and state government agencies, as well as
a number of nonprofit organizations and foundations from within and outside Alaska.
Grant Specialists with ANTHC's Grants Management and Compliance Department work to
coordinate grant reporting activities with project managers, communicate with external funding
agencies to ensure goals and objectives are met, and ensure grant reports/closeout data are submitted on time. ANTHC's project managers, supervisory personnel, and accounting staff manage
grant-funded projects according to the grantor's specific requirements. ANTHC's Grant Specialists
use the Microsoft Office suite of software to monitor grant activities and reporting requirements, working closely with project managers and finance staff to continuously review and improve
departmental operations.
ANTHC prepares quarterly reports on all of the capital projects it currently manages. This same
methodology of reporting will be utilized for this project should grant funds be awarded to the Yakutat Tlingit Tribe. ANTHC will work with the Yakutat Tlingit Tribe to provide monthly financial and narrative
reports as required by AEA. Financial reports with detailed expense information for labor, materials,
travel, and indirect utilization for the project will be provided. Narrative reporting will discuss the status of the project and any challenges that arise in carrying out the scope of work as described in
this application.
ANTHC Energy Department's Project Manager, Katya Karankevich, will serve as the project
manager responsible for tracking the progress of this project using ANTHC's budget and project
AEA - 23046 Page 10 of 104
REF Round 15 Application
Yakutat Community Health Center Heat Recovery
tracking software tools (Cognito, INFOR, etc.) Written monthly progress reports will be provided to the AEA project manager as required by the terms and conditions of the grant. Meetings will be conducted by ANTHC, the Yakutat Tlingit Tribe, AEA, and other project stakeholders as needed to
discuss the status of the project on an ongoing basis.
3.3.2 Financial Reporting
Describe the controls that will be utilized to ensure that only costs that are reasonable, ordinary and necessary will be allocated to this project. Also discuss the controls in place that will ensure
that no expenses for overhead, or any other unallowable costs will be requested for reimbursement from the REF Grant Program.
The Yakutat Tlingit Tribe will enter into a Cooperative Project Agreement (CPA) with ANTHC to
provide comprehensive project and financial management for the proposed project. The following
information illustrates the organizational capacity and financial controls that are in place to ensure grant funds are managed efficiently:
ANTHC is a large organization with over 3,018 employees and an annual operating budget of $736.6 million. Of that amount, approximately $308.5 million is grant-funded. The Consortium’s
Chief Financial Officer has the overall responsibility for the fiscal and administrative oversight of
grant awards.
All funds awarded to the Yakutat Tlingit Tribe and contracted to ANTHC will be maintained and accounted for separately and distinctly from other sources of revenue/funding. Internal ANTHC controls are in place to ensure that federal and state funds are used solely for the authorized
purposes intended, including multiple levels of approval ensuring award funds are managed properly.
To this purpose ANTHC maintains Grants Management and a Compliance teams to ensure it is compliant with all federal, state, and private funding as well as the Uniform Administrative Requirements Cost Principles and Audit Requirements for federal awards (2 CFR Part 200).
ANTHC performs in-house financial management and has sufficient internal controls in place to establish proper segregation of time and duties necessary to consistently reporting consistent
costs to funding agencies. These controls likewise prevent incurring obligations in excess of the
total funds available for the grant. ANTHC meets all funder’s requirements and assigns a unique accounting – cost center number to each award received. ANTHC also has an annual independent
audit completed.
The ANTHC Procurement and Contracting Department works with program managers to ensure
appropriate scopes of work, performance measures, and compliance requirements are
incorporated into all organizational contracts. This is completed through a computerized contracts procurement and management software.
The Finance Department oversees the implementation and maintenance of internal monetary and accounting controls, follows corporate accounting policies, provides compliance monitoring and
enforcement of financial requirements, and performs mandated record retention for the Consortium.
ANTHC will provide records and accounting records available to state and federal auditors on request. Project finance information will be kept in ANTHC Infor, a job cost accounting software

Richard is the manager of the Contract Delivery Team at ANTHC and will be assisting in procurement for the design component of the project. He has been writing, managing, and
executing complex contracts and selecting contractors for over eight years.
4.2 Local Workforce
Describe how the project will use local labor or train a local labor workforce.
During investigation and design, the community will be engaged and solicited for input and
comment. Additionally, the facilities manager and maintenance staff at the YCHC will be provided
personalized on the ground training in systems operation, in addition to training provided to the AVEC power plant operators.
Completion of the activities detailed in this project’s scope of work will rely largely upon the ANTHC Rural Energy Program’s extensive experience in managing energy projects in rural Alaska and by
selecting qualified competent contractors to complete construction of the project. It is anticipated
that the contracted construction services will ultimately hire a portion of their construction crew from the local workforce.

5.1 Resource Availability
5.1.1 Assessment of Proposed Energy Resource Describe the potential extent/amount of the energy resource that is available, including average
resource availability on an annual basis. For pre-construction applications, describe the resource to
the extent known. For design and permitting or construction projects, please provide feasibility documents, design documents, and permitting documents (if applicable) as attachments to this
application (See Section 11). Likelihood of the resource being available over the life of the project.
See the “Resource Assessment” section of the appropriate Best Practice Checklist for additional guidance.
Yakutat's power plant currently employs heat recovery, which is distributed to the Yakutat High School and Elementary school, as well as the vocational shop, public safety building, and housing
for the power plant maintenance workers. This heat is provided at no cost due to a pre-existing
agreement established when the power plant was sold to the power plant operator (AVEC). The heating load from the connected buildings creates a peak load of approximately 580 MBH. The health
center adds an additional 332 MBH peak load for a total combined peak load of 912 MBH. The summary of fuel use per building, per the ANTHC Heat Recovery Feasibility Study, is below:
Based on analysis of the power production from the generators and the produced heat sent to the radiators, the existing power plant is fully capable of delivering between 1,021 to 1,381 MBH of recovered heat after line losses are subtracted, so there is sufficient capacity to fully meet the existing
heat recovery demand as well as fully serve the new health center with a new heat recovery system.
5.1.2 Alternatives to Proposed Energy Resource Describe the pros and cons of your proposed energy resource versus other alternatives that may
be available for the market to be served by your project.
Currently, diesel power is the only community-scale power system available in Yakutat, resulting in
expensive electricity prices for the community. Electric resistive, heat-pump, and other electrically-
based alternatives were considered too expensive for evaluation.
There are no significant proximal geothermal heating opportunities for the YCHC. Biomass heating alternatives have been considered and pursued by the community in the past with limited success due to high costs and challenging maintenance and operations requirements. While biomass is a
readily available local fuel source, the procurement, processing, and operation requirements of biomass energy are more emission-intensive and expensive than utilizing available excess heat from the AVEC power plant.
Solar Thermal was also considered. However, due to the precipitous maritime environment in Yakutat, extensive snow loads, and difficulty accessing the health center roof for snow removal,
this alternative was not closely investigated as it was determined unlikely to be cost-effective.

5.1.3 Permits
Provide the following information as it may relate to permitting and how you intend to address outstanding permit issues. See the “Environmental and Permitting Risks” section of the appropriate Best Practice Checklist for additional guidance.
•List of applicable permits
•Anticipated permitting timeline
•Identify and describe potential barriers including potential permit timing issues, public
opposition that may result in difficulty obtaining permits, and other permitting barriers
Multiple permits are anticipated to be required for the project.
State of Alaska Fire Marshal Permit Fire Marshal permits are intended to be submitted by the State of Alaska Plan Review Bureau at
95% design, with expected turnaround of permits to occur within one month.
State of Alaska Directional Drilling Permit
In order to install the heat recovery piping beneath the DOT road located between the power plant and the Health Center, directional drilling is proposed. This will require a permit from DOT, which
has already been secured by ANTHC for these purposes.
5.2 Project Site
Describe the availability of the site and its suitability for the proposed energy system. 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. See the “Site control” section of the
appropriate Best Practice Checklist for additional guidance.
In general, the soils in Yakutat are suitable for buried utilities, with no permafrost or tundra wetlands to complicated routing. The proposed site routes piping through primarily previously
disturbed soils and on cleared property to reduce site development costs.
Property ownership is clearly defined for this project. The YCHC maintains site control for the
Health center site, upon which the majority of the project will occur. AVEC, who is actively
supporting this project, has deeds for both parcels upon which their property is located and where the heat recovery piping would be routed. Lastly, the DOT ROW under which the heat recovery
piping would be routed has already been permitted for directional drillings.
The two AVEC Deeds, YCHC Surveyed Plat, and the DOT Directional Drilling Permit, are attached
in Appendix C of this application.
5.3 Project Technical & Environmental Risk
5.3.1 Technical Risk Describe potential technical risks and how you would address them.
•Which tasks are expected to be most challenging?
•How will the project team reduce the risk of these tasks?
•What internal controls will be put in place to limit and deal with technical risks?
See the “Common Planning Risks” section of the appropriate Best Practice Checklist for additional
guidance.
Two tasks have been identified as the most technically challenging for this project.
AEA - 23046 Page 16 of 104
REF Round 15 Application
Yakutat Community Health Center Heat Recovery
The first is the burial of the pre-insulated pipe. This process can be expensive due to high equipment needs and potential trench management complications. The paved DOT road bisecting the proposed
pipe layout alignment further complicates the pipe burial effort, as this infrastructure must be accommodated. ANTHC proposes and has already received permits to use directional drilling as a
workaround that lowers equipment costs and avoids traffic management/other risks associated with
the reconstruction of the DOT road. Directional drilling will allow for the burial of the pipe beneath the road without having to disturb the road surface or impact traffic by horizontally drilling a hole for the
heat recovery piping beneath the existing roadway. The Directional Drilling Permit is provided in
Appendix A of this application.
The second technical risk is the minimal space available for the intertie of the heat recovery system
to the existing YCHC diesel-fired heating system. The mechanical room where the intertie must take place has minimal unused space. The design team will therefore require equipment placement and
maintenance of appropriate clearances for to be precise and consistent. However, as opposed to
most heat recovery projects, the facility being served was newly constructed in 2019. As such, the existing equipment is of premium efficiency and meets all current requirements. Significant attention
will be paid, throughout the design process, to identifying the appropriate design clearances and placement of equipment to minimize the associated risks.
The specific risks of the project will be primarily controlled by an extensive design review. Additionally, ANTHC will secure construction administration services from a qualified engineering firm (likely the design engineers) to oversee submittal, review, RFIs, and field inspections of the
construction.
Other common risks in rural Alaska, such as barge scheduling, severe weather, and general remote
logistics, do not apply to Yakutat, which has regular barge service year-round and an airport with major cargo and airline access.
5.3.2 Environmental Risk
Explain whether the following environmental and land use issues apply, and if so which project
team members will be involved and how the issues will be addressed. See the “Environmental and Permitting Risks” section of the appropriate Best Practice Checklist for additional guidance.
•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 describe other potential barriers
ANTHC will consider all potential environmental concerns associated with this project as identified by the feasibility study, recommendations from AEA, and associated agencies for permitting purposes, etc. ANTHC is very experienced in utilizing a variety of federal environmental review
standards to include the Indian Health Service, USDA, Denali Commission, and other environmental review procedures for conducting environmental analyses of all health and projects
in all stages of development.

Threatened or Endangered Species:
A listing of all endangered or threatened plant and animal species for Alaska was obtained through the USFWS. None of the species identified in the area list of endangered or threatened animal or
plant species have critical habitats near the project. It was concluded that the project is not likely to impact endangered or threatened species.
Habitat Issues:
The project is located entirely in previously developed or disturbed areas of Yakutat, and no habitat
is anticipated to be impacted.
Wetlands and other Protected Areas:
No wetlands or protected areas were identified for the project area by the USFWS National
Wetlands Inventory mapper.
Archeological and Historical Resources:
No archaeological or historical resources are anticipated.
State Historic Preservation Office:
An SHPO 106 Consultation will be formally conducted during design.
Land Development Constraints:
As discussed previously, a DOT road crossing is the greatest land development constraint. A permit has been secured to conduct directional drilling beneath the roadway. The permit is
included in Appendix C of this application.
Telecommunications Interference:
None anticipated; a nearby FAA radio transmitter site is no longer functioning, even if the project were to operate telecommunications equipment, which it does not.
Aviation Considerations: No aviation impacts are anticipated with this project, as all construction is located belowground or interior to existing facilities.
Visual and Aesthetic Impacts:
Visual and aesthetic impacts were not evaluated in the feasibility study. However, it is not
anticipated that there will be any significant impacts from the completed project as all piping will be routed below ground, and all other installed equipment will be located inside existing preexisting
facilities. It is anticipated that the reduced firing of diesel boilers in the health center will reduce
noise and improve indoor air quality.
5.4 Technical Feasibility of Proposed Energy System
In this section you will describe and give details of the existing and proposed systems. The information for existing system will be used as the baseline the proposal is compared to and also
used to make sure that proposed system can be integrated.

Yakutat Community Health Center currently operates an oil-fired fuel boiler that provides heating to the air handler, which provides space heating services to the facility, and to indirect hot water
heaters. The heating system operated a DDC control system and a series of zones and controllers
to control temperatures throughout the facility. The current system uses over 18,000 gallons of diesel fuel annually. Annual fuel usage data is attached in Appendix C of this application.
The AVEC power plant currently operates a series of diesel generators with jacket cooling systems. The jacket cooling system currently provides heat to an existing heat recovery service providing heat
to the City and Borough of Yakutat School and Public Works facilities. There is excess heat capacity in the cooling system available to provide heating benefits to the Yakutat Community Health Center based upon the assessment of the Heat Recovery Feasibility study included in Appendix A.

project, over the life of the project. Explain how the forecast was developed and provide year by year forecasts. As appropriate, include expected changes to energy demand, peak load, seasonal variations, etc. that will affect the project.
Yakutat’s population has been growing in recent years and is expected to continue to do so. The establishment of a substantial Community Health Center with providers and extensive health
services has encouraged residents to return to the community. Population Study projections performed by KBL Engineering Services are identified below:
AEA - 23046 Page 21 of 104
REF Round 15 Application
Yakutat Community Health Center Heat Recovery
With population growth in Yakutat it can be anticipated that electrical demand will increase, allowing for additional heat to be captured from the generators. Further, this can be expected to result in increased usage and potential expansion of the health center, further improving the
potential benefits of the project.
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
•The total proposed capacity and a description of how the capacity was determined
•Integration plan, including upgrades needed to existing system(s) to integrate renewableenergy system: Include a description of the controls, storage, secondary loads, distribution
upgrades that will be included in the project
•Civil infrastructure that will be completed as part of the project — buildings, roads, etc.
•Include what backup and/or supplemental system will be in place
See the “Proposed System Design” section of the appropriate Best Practice Checklist for additionalguidance.
Heat Recovery System Description and Operation: The heat recovery system captures heat generated by the AVEC generators at the community power
plant that is typically rejected to the atmosphere by the radiators and thereby wasted as a source of
heat. Heat recovery systems capture or ‘recover’ this lost heat and transfer it via piping to end users. The objective of this application/project is to reduce consumption (and the associated costs) of
heating fuel by utilizing available recovered heat in its place. Although heat recovery is an excellent
method of reducing heating-related fuel costs, recovered heat is a supplementary heat source. It is, therefore, imperative that the end-user facility heating systems are operational at all times in case
the heat recovery system becomes operational for any reason.
Heat is recovered by piping hot engine coolant through a plate heat exchanger located at the power
plant. Heat is transferred from the engine coolant through the recovered heat loop without mixing the fluids. Controls at the power plant are used to prevent sub-cooling of the generator engines and reduce electric power production efficiency. The recovered heat fluid is pumped through a buried
insulated pipe to the end-user facilities and is typically tied into the end-user heating system through a plate heat exchanger.
AVEC Plant Tie-In:
To the greatest extent possible, the generator side of the heat recovery heat exchanger will remain as is. The only modifications will be made in order to verify performance and replace the AMOT
thermostatic valves to the radiators if they’re leaking. The user side of the system will receive new controls, pumps, expansion tanks, air separators, and other appurtenances as needed to refurbish the existing system and ensure a 25-year life expectancy for the system. All facility heat recovery
piping will receive a minimum of 1.5 inches of pipe insulation and have an aluminum jacket where they are exposed to the weather. New propylene glycol will be provided to ensure the system is
protected from freezing.
Recovered Heat Loop:
The proposed piping is based on Rovanco Rhinoflex pre-insulated PEX. It is recommended that
PPRCT Carrier pipe inside Arctic pipe be considered as an additive alternate during the bid phase if funds allow. The piping will be buried sufficiently deep outside of the roadbed to protect the piping
from accidental damage (2-4 feet down, depending on location). Road crossings will be run inside
the culvert under the road bed. Circulation pumps at the AVEC facility will circulate heating fluid from
AEA - 23046 Page 22 of 104
REF Round 15 Application
Yakutat Community Health Center Heat Recovery
the AVEC facility. When the system is running at part load conditions, the system will throttle down heating fluid flow to minimize power consumption.
End-User building tie-ins: End-user building tie-ins will be replaced. The new tie-ins will consist of brazed plate heat exchangers with a heat injection or building circulation pump on the building side. Controls prevent the back-
feeding of heat to AVEC or other users. Plate heat exchangers located in the end-user mechanical room will be tied into the boiler return piping to inject heat into the building heating system upstream
of the existing heating equipment (if present) or to isolate the building circulation system from the
heat recovery system (if no boilers are present). The maximum anticipated delivered recovered heat supply temperature is about 180F. If there is insufficient heat to meet the building heating load, the
heat recovery controls will lock out the heat recovery supply if the temperature falls below a pre-set minimum, providing prioritization of available heat.
Typical indoor piping will be a type L copper tube with solder joints, or if the piping is 3 inches or larger, welded steel piping with flanged connections to heating equipment. All piping will include a minimum of 1-inch insulation with a service Jacket. Flexibility will be provided where required for
thermal expansion and differential movement. Air vents, thermometers, pressure gauges, drain valves, and pressure relief valves will be provided.
Each end-user facility will also receive a BTU meter to provide recovered heat use totalization and instantaneous use.

Circulation pumps at the AVEC facility will circulate heating fluid from the AVEC generators through the heat exchangers to the district heating loop Heat will be available whenever the AVEC diesel generators are operating, which is anticipated to be 24/7, 365 days per year.
The heat recovery system will be controlled and managed by AVEC using AVEC’s standard thermal management panel. This consists of a Primary Logic Controller (PLC), which monitors and controls
the heat recovery system, protects the generators from low temperatures, and monitors recovered

heat use. When the generation system is running at partial load conditions, the PLC will throttle down heating fluid flow to minimize power consumption.
End-user systems will use an off-the-shelf differential temperature controller to start/stop a heat injection pump and control a modulating flow control valve to provide load shedding and freeze protection and prevent back-feeding of boiler heat into the heat recovery system. In addition, a BTU
meter will be provided, displaying instantaneous temperatures and heat transfer, as well as totalizing BTUs used.
Controls prevent the back-feeding of heat to both AVEC and other users. Plate heat exchangers located in the end-user mechanical room will be tied into the boiler return piping to inject heat into
the building heating system upstream of the existing heating equipment (if present) or to isolate the building circulation system from the heat recovery system (if no boilers are present). The maximum anticipated delivered recovered heat supply temperature is about 180F. If there is insufficient heat
to meet the building heating load and the temperature falls below a pre-set minimum, the heat recovery controls will lock out the heat recovery supply providing prioritization of available heat.

included as economic benefits of the project.
Where appropriate, describe the anticipated energy cost in the community, or whatever will be
affected by the project, over the life of the project. Explain how the forecast was developed and provide year-by-year forecasts.
The economic model used by AEA is available at https://www.akenergyauthority.org/What-We-Do/Grants-Loans/Renewable-Energy-Fund/2022-REF-Application . 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 anticipated fuel savings of the facility is over 18,400 gallons of fuel per year, or at current fuel
prices, $113,344. Fuel savings were calculated at current fuel prices paid by the Yakutat Community Health Center and adjusted annually for the life of the project based upon the percentage price
changes reflected in the AEA Economic Fuel Model Duel Fuel prices rate established for Yakutat.
The significant cost savings will offset a major portion of the annual operating budget for the YCHC facility. Additional maintenance savings will be achieved through reduced operation and
maintenance of the fuel fired boilers at the health center, as well as a voided replacement cost of the
boilers in the center. The combined impact of avoided costs and risks from transitioning to a heat retention system will make it possible for YCC to expanded provision of health services at YCHC.
According to a May 2020 publication by Raghupathi et.al. “increased healthcare expenditure…” (like
that made possible by this project) “…is positively associated with the indicators of labor productivity,
AEA - 23046 Page 26 of 104
REF Round 15 Application

personal spending, and GDP.” This healthcare spending therefore represents a potential economic boon as well
6.1.3 Economic Risks Discuss potential issues that could make the project uneconomic to operate and how the project
team will address the issues. Factors may include:
•Low prices for diesel and/or heating oil
•Other projects developed in community
•Reductions in expected energy demand: Is there a risk of an insufficient market for energy
produced over the life of the project.
•Deferred and/or inadequate facility maintenance
•Other factors
Due to the low operations and maintenance cost of the proposed system and the near 100% elimination of heating fuel demand at the health center post-project completion, it is anticipated that
the relative economic risks of the project are minimal. Low prices for diesel fuel could potentially reduce the benefits of the project to YTT. However, heating fuel prices are historically volatile, and there is little reason to anticipate that fuel oil prices will stay low for the long term.
Various entities in Yakutat have or are considering pursuing alternative electric generation sources
which could reduce the heat recovery benefits available. ANTHC has developed a preliminary
analysis for a community-scale Solar PV project to benefit the community. However, due to the seasonal limitations of solar power (summer only) and winter primary heating demand, these
projects are not anticipated to significantly impact the proposed project's economic benefits. Some
entities in Yakutat are pursuing wave energy generation, but the high capital cost, risk, and relatively early-stage development of the technology make this renewable energy source unlikely
to impact Yakutat's heat recovery benefit for decades.
Yakutat's population is growing, and the community is, therefore, likely to see increased electric
demand over time. Yakutat currently does not have an extensive fleet of electric vehicles. However, due to the relatively small road system and sprawling layout of the community, which encourages vehicle use, it is anticipated electric vehicle use will dramatically increase demand on
the grid in the years ahead. The likely result is increased electrical demand and correspondingly increased available heat benefits from the proposed project.
Deferred and or inadequate facility maintenance is also a risk that has been challenging for the existing heat recovery project. However, since AVEC took ownership and responsibility for the
Yakutat power plant in 2017, improved maintenance practices have been implemented, and it is
anticipated that this intervention will continue to defer this risk.
6.1.4 Public Benefit for Projects with Direct Private Sector Sales

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 the primary beneficiary of this project is the YCHC, which serves as Yakutat's only source of healthcare, it is anticipated that the project will result in the improved provision of health services to community members. With the increased availability of discretionary revenues, YCHC can
potentially expand behavioral health and wellness services to support the community. With expanded services and reduced emissions from the combustion of fossil fuels at the health center, significant health benefits are anticipated to be realized for the entire community.
Additionally, the project will reduce dependence on imported energy resources. This reduced
dependence/consumption will alleviate the burdens associated with the storage of the offset fuel that would otherwise be consumed. This has implications for both cost savings associated with storage and increased access for other fuel-consuming entities, both of which would benefit the
community in a multitude of ways.
The construction of the health center in 2019 and the availability of health services have
encouraged year-round population growth in the community; expanded health services increase local employment and access to health care for all community members. It is self-evident that improved access to care within a community improves health outcomes for community members.

SECTION 7 – SUSTAINABILITY
Describe your plan for operating the completed project so that it will be sustainable throughout its
economic life.
7.1.1 Operation and Maintenance Sustainability
Demonstrate the capacity to provide for the long-term operation and maintenance of the proposed
project for its expected life
•Provide examples of success with similar or related long-term operations
•Describe the key personnel that will be available for operating and maintaining theinfrastructure.
•Describe the training plan for existing and future employees to become proficient at operatingand maintaining the proposed system.
•Describe the systems that will be used to track necessary supplies
•Describe the system will be used to ensure that scheduled maintenance is performed
The City and Borough of Yakutat has enjoyed the benefits of the existing heat recovery system providing heating for the community school and public works facility for 27 years. AVEC operates
heat recovery systems in dozens of communities across rural Alaska, providing significant benefits
for rate holders in each community.
AVEC power plant personnel will be responsible for maintaining the AVEC side of the heat recovery
system. The AVEC operators have experience with operating power generating equipment, fuel systems and maintaining diesel generators. They have the ability to work with minimal supervision
and carry out daily duties. AVEC operators capably follow instructions from manuals, identify and orders parts, materials and supplies.
The Yakutat Community Health Center maintains both day-to-day maintenance staff as well as a managerial position for oversight of the facility.
ANTHC Tribal Utility Support will prepare a training plan and conduct field training for both operations of the system and preventative maintenance training for the system.
Supply requirements for operating the heat recovery system once constructed will be minimal. AVEC and YTT will add glycol, as needed, on their respective sides of the system.
Key practices to ensure functionality and identify repair requirements for the system will include observing pressure drop across the heat exchangers, keeping track of heat delivered through the
installed BTU meter, and keeping an eye on fuel use at the health center. These tasks will be
performed by maintenance personnel at the Yakutat Community Health Center.
A preventative maintenance plan will be used to track critical scheduled maintenance. The health
center will contribute $40,000 per year to a capital replacement fund that will allow for replacement or upgrades to the system after its end of life (25 years from installation). The capital replacement
fund balance will be utilized as matching funds for system replacement. Long-term costs have been assessed along with monitoring and evaluation, and maintenance and are acceptable for future budgets.
7.1.2 Financial Sustainability
•Describe the process used (or propose to use) to account for operational and capital costs.
AEA - 23046 Page 29 of 104
REF Round 15 Application
Yakutat Community Health Center Heat Recovery
•Describe how rates are determined (or will be determined). What process is required to setrates?
•Describe how you ensure that revenue is collected.
•If you will not be selling energy, explain how you will ensure that the completed project will befinancially sustainable for its useful life.
Costs for operating the heat recovery system will be tracked within the YCHC financial system and coded for the facilities department.
Savings will be entirely through avoided fuel use and will not result in collected revenues or reduced rates.
Fuel savings benefits will be shared within the project, with an estimated 30% of heat savings anticipated to be provided to AVEC with a heat sales agreement between the two entities. Heat Sales will be provided based on outputs from the BTU meter. If the meter fails, an estimated
annual benefit determined by avoided fuel cost, applied monthly, will be used instead. Heat sales will be collected on the monthly electrical bill for the health center. An example Heat Sales Agreement demonstrating fuel costs is attached for reference in Appendix C.
The anticipated net annual fuel savings for the project results in over $113,000 in annual saving;
with 30% of savings recognized by AVEC and 70% of savings recognized by the Health Center,
there will be sufficient savings to cover the anticipated $12,730 annual operations and maintenance cost as well as set aside $40,000 annually for a replacement and major repair fund
for the heat recovery system.
7.1.2.1 Revenue Sources
Briefly explain what if any effect your project will have on electrical rates in the proposed benefit
area over the life of the project. If there is expected to be multiple rates for electricity, such as a separate rate for intermittent heat, explain what the rates will be and how they will be determined
Collect sufficient revenue to cover operational and capital costs
•What is the expected cost-based rate (as consistent with RFA requirements)
•If you expect to have multiple rate classes, such as excess electricity for heat, explain what
those rates are expected to be and how those rates account for the costs of delivering the energy (see AEA’s white paper on excess electricity for heat).
•Annual customer revenue sufficient to cover costs
•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)
This project is not anticipated to reduce electrical consumption rates for Yakutat and will only result
in reduced costs incurred for procurement of fuel. No additional revenue streams or incentives are
anticipated for the project.
7.1.2.2 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 (consistent with the
Section 3.16 of the RFA)

ANTHC has completed an extensive Heat Recovery Feasibility Study that considered costs, potential benefits, and ancillary impacts to other heat recovery users. This document in Appendix
A. Based upon the simplicity of the project and ANTHC’s extensive experience with similar systemsthroughout rural Alaska, it is anticipated that this project should seek funding for Phase III designand Phase IV construction concurrently. Additional project development isn’t required to accurately
forecast project costs and potential savings.
This application considered design and construction simultaneously. The design is anticipated to
be a straight forward design generally, and able make use of previous design details and experience with heat recovery systems. With funding secured through tribal matching funds, design can proceed immediately upon award of the project. ANTHC has secured site control and is
prepared to advance the project quickly upon receipt of funding.
While the most significant permit requirement is the Fire Marshall Plan Review, this can only be
accomplished with engineering documents. The additional major permit required for directional drilling beneath and through the DOT right of way has already been acquired by ANTHC and is
provided in Appendix C of this application.
8.2 Demand- or Supply-Side Efficiency Upgrades

Energy efficiency work has not been pursued directly in relation to the heat recovery project due to the “like new” construction of the Yakutat Community Health Center. The facility was completed in 2019 with strict energy efficiency considerations observed; no additional efficiency measures are
likely to be beneficial from an economic perspective.
SECTION 9 – LOCAL SUPPORT AND OPPOSITION Describe local support and opposition, known or anticipated, for the project. Include letters,
resolutions, or other documentation of local support from the community that would benefit from this project. Provide letters of support, memorandum of understandings, cooperative agreements between the applicant, the utility, local government and project partners. The documentation of
support must be dated within one year of the RFA date of October 4, 2022. Please note that letters
of support from legislators do not count toward this criterion
Local support for this project has been secured from the Alaska Village Electric Cooperative
(AVEC) and the City and Borough of Yakutat (CBY), in addition to the YTT and ANTHC.
SECTION 10 – COMPLIANCE WITH OTHER AWARDS
Identify other grants that may have been previously awarded to the Applicant by the Authority for this or any other project. Describe the degree you have been able to meet the requirements of
previous grants including project deadlines, reporting, and information requests.
YTT has never received funding from the Alaska Energy Authority Renewable Energy Fund. The
City and Borough of Yakutat have previously applied for and closed out an award from AEA for the design and construction of a biomass project which was ultimately not constructed.
ANTHC has provided project and grant management services for 26 grants from the AEA REF. The Rural Energy Program team has managed the installation of heat recovery systems for the
communities of Emmonak, Russian Mission, and Chevak through the Renewable Energy Fund
program, in addition to many other projects. Currently, ANTHC is managing AEA funding for the Mertarvik-Newtok BFU project - grant agreement #7210026.
ANTHC has been successful in these projects due to the various divisions and controls the organization has in place to successfully manage grant-funded projects. The Consortium is
structured to allow for maximum oversight of project management and financial reporting activities. DEHE leadership has extensive experience coordinating grant-funded projects in rural Alaska
communities and will be responsible for managing project tasks to completion. To this end, ANTHC
will utilize the various organizational divisions, controls, personnel, and processes it has established for these functions.
In addition to the staff identified in Section 4, ANTHC’s DEHE has the benefit of drawing from the expertise of over twenty engineers presently licensed in the State of Alaska across multiple
disciplines, with additional staff actively pursuing licensure, several of whom will likely have attained
licensure by the beginning of the project period. ANTHC’s DEHE also has multiple Certified Energy Managers (CEM) on staff, with several others working towards that certification. The Grants
Management and Compliance department is staffed to ensure that financial management and grant
reporting are completed accurately and on time for all restricted sources of funding received, which includes funds received through contracting with entities that ANTHC partners with to complete
grant-funded projects.

Yakutat Heat Recovery Replacement – Feasibility Study
Executive Summary
This memo recommends the immediate replacement of the failing 27 year old Heat Recovery system in
Yakutat that serves five community buildings. If replaced, there will be sufficient heating capacity to add
the existing health clinic building. The replacement system with the community clinic added will avoid
38,100 gals of fuel use by the community annually.
The existing heat recovery system is past its usable life and in danger of imminent failure, risking large-
scale infrastructure damage. All three school buildings (elementary school, high school and wood-shop)
tied to this system have no sources of backup heating and have been experiencing inadequate heat
supply for several years due to the degraded system function. The distribution loop leaks about 55
gallons every 10 days, causing no delivery of heat when system pressure drops to zero. While originally
filled with Propylene Glycol for freeze protection, it is now filled with water due to the unsustainable
volume of fluid loss and high cost of glycol. The system is not protected from freezing, so if it fails in the
winter, the heat distribution piping will freeze and it will not be possible to restore any level of function
before spring. This failure would close down all k-12 classrooms in Yakutat until funds have been
secured for repair of the existing frozen piping inside the school buildings, in addition to the design and
construction of a new heat recovery system, which would take three to four years on average to
complete.
The cost of replacing this system with the additional loop extension to the clinic is roughly 3.07 million
dollars and will save up to $14.3 million in inflation adjusted avoided fuel costs over the 25 year life of
the system. Due to the large quantity of heat produced at the power plant and the high cost of
heating fuel in Yakutat at $6.27 per gallon, the discounted benefit / cost ratio for this project,
including O&M costs, is 4.4. Currently, AVEC does not charge users of the existing heating loop for
heat, but could charge the new clinic for half the cost of an equivalent gallon of fuel, giving the utility
some O+M budget for their side of the heat exchangers.
This feasibility study examines the available heat created by the power plant and the heating demands
of the five buildings that are on the existing loop, plus the additional clinic. It proposes a cost estimate
for the replacement of the system and expansion to the community clinic. It is the opinion of ANTHC
that to increase resiliency and self-sufficiency for this community and decrease the likelihood of
inevitable freeze up from the current system failure, that the heat recovery system be replaced as
soon as possible.
AEA - 23046 Page 37 of 104
Introduction
Yakutat’s existing heat recovery system provides all of the heating needs for the high school, the
elementary school, the high school wood shop, the Public Safety Office and AVEC housing. This 27 year
old system has saved approximately $ 239,000 annually in avoided heating fuel use at today’s retail
heating fuel costs. The system has performed well enough that during the last ten years, the oil-fired
heating systems were removed from the schools when they reached their end of life and were not
replaced, due to lack of funds. The AVEC housing unit has never had a boiler system and also relies 100%
on recovered heat. The Public Safety Office does have a boiler system in addition to access to recovered
heat, but it is used rarely.
The lack of a functional oil fired heating system in the public schools has led to a dire situation. The
existing heat recovery system has surpassed its usable life and failure would destroy the plumbing
infrastructure and likely flood the school buildings. The high school is also the community’s emergency
meeting place, as written in their disaster mitigation plan. Without reliable heat from a new heat
recovery system, the ability of the school buildings to stay open throughout a winter or an emergency is
vastly diminished.
The Public Safety Office and AVEC housing were added to the heat recovery system at some point
after construction of the original system. These additions were done without proper insulation,
protection from damage, or integration with the original heat recovery system. The result is the loss of
significant amounts of heat to the environment, sub optimal performance, and increased risk of
catastrophic failure of the system.
The Alaska Native Tribal Health Consortium (ANTHC) has reviewed the likely performance of a
replacement heat recovery system and developed a budgetary cost for providing a
replacement recovered heat system to serve the existing users and also the Yakutat public
health clinic.
For the purposes of this memo, it was assumed that a new heat recovery system would be
installed essentially in the same location as the existing system, which would be demolished as
part of the project.
Additional assumptions have been made in the development of this report, including, but not limited
to: flow rates and pressure drops of the power plant heat recovery system, location of road crossings
and extension line to the clinic, access to pipeline bedding, and absence of environmental
contamination along the pipeline routes. It is anticipated that refinements in heat recovery pipe size
and routing, pump and heat exchanger sizing, and other design elements will be required as the project
progresses to final design.
Available information was obtained from AVEC on electrical loads and generator heat production.
End user annual fuel use was based on energy audits performed at the school buildings, public safety
building, and community clinic along with BTU meter data obtained during the heating season
Estimated recovered heat utilization:
HOMER PRO was used to model the available recovered heat at the power plant as well as the
recovered heat demand by the users. This model was also used to ensure that a planned potential
future addition of a 1.5 MW solar array would not adversely affect the available recovered heat benefit
to the community. The results of the model were incorporated into a heat recovery utilization
spreadsheet to estimate the powerhouse and pipeline losses of the system and compare to demand.
The following is a summary of estimated annual fuel use.

Graph 1: Historical Performance
Heat Recovery System Description and Operation:
The Heat recovery system captures jacket water heat generated by the AVEC power plant that is
typically rejected to the atmosphere by the radiators, thus wasted as a source of heat. The recovered
heat is transferred via piping to the end users. The objective of this system replacement is to reduce the
consumption of expensive heating fuel by utilizing available recovered heat.
Although heat recovery is an excellent method of reducing heating fuel costs, recovered heat is a
supplementary heat source and it is imperative that the end-user facility heating systems are
operational at all times. It is recommended that the school buildings install another heating
source in addition to replacing recovered heat.
AEA - 23046 Page 39 of 104
Hot engine coolant is piped through a plate heat exchanger located at the power plant. Heat is
transferred from the engine coolant to the recovered heat loop without mixing the fluids. Controls at
the power plant are used to prevent sub-cooling of the generator engines and reducing electric power
production efficiency. The recovered heat fluid is pumped through buried insulated pipe to the end user
facilities, and is typically tied into the end user heating system using a plate heat exchanger.
AVEC Plant Tie-In:
To the greatest extent possible, the generator side of the heat recovery heat exchanger will remain as is,
other than verifying performance and replacing the AMOT thermostatic valves to the radiators if they’re
leaking. The user side of the system will receive new controls, pumps, expansion tanks, air separators,
and other appurtenances as needed to refurbish the existing system and ensure a 25 year life. All
facility heat recovery piping will receive a minimum of 1.5 inches of pipe insulation and have an
aluminum jacket where exposed to the weather. New Propylene glycol will be provided to ensure the
system is freeze protected.
Recovered Heat Loop:
The proposed piping is based on Rovanco Rhinoflex pre-insulated PEX. It is recommended that PPRCT
Carrier pipe inside arctic pipe be considered as an additive alternate during the bid phase if funds allow.
The piping will be buried sufficiently deep outside of the road bed to protect the piping from accidental
damage (2-4 feet down, depending on location). Road crossings will be run inside culvert under the road
bed.
Circulation pumps at the AVEC facility will circulate heating fluid from the AVEC facility. When the
system is running at part load conditions, the system will throttle down heating fluid flow to minimize
power consumption.
End-User building tie-ins:
End user building tie-ins will be replaced. The new tie-ins will consist of brazed plate heat exchangers
with a heat injection or building circulation pump on the building side. Controls prevent back-feeding of
heat to AVEC or other users. Plate heat exchangers located in the end-user mechanical room will be tied
into the boiler return piping to inject heat into the building heating system upstream of the existing
heating equipment (if present) or to isolate the building circulation system from the heat recovery
system (if no boilers are present). The maximum anticipated delivered recovered heat supply
temperature is about 180F. If there is insufficient heat to meet the building heating load, the heat
recovery controls will lock out the heat recovery supply if the temperature falls below a pre-set
minimum, providing prioritization of available heat.
Typical indoor piping will be type L copper tube with solder joints, or if the piping is 3 inch or larger,
welded steel piping with flanged connections to heating equipment. All piping will include a minimum
of 1 inch insulation with an all service Jacket. Flexibility will be provided where required for thermal
expansion and differential movement. Air vents, thermometers, pressure gauges, drain valves, and
pressure relief valves will be provided.
Each end user facility will also receive a BTU meter to provide recovered heat use totalization and
instantaneous use.
AEA - 23046 Page 40 of 104
Rights of Way Issues:
There are no apparent conflicts with right-of way for the piping between the power plant and end user
buildings, as the route is entirely within existing road right of way and the property of the end users.
This will be verified through public records and site surveys during design.
A Heat Sales / Right of Entry Agreement will be required between AVEC and the clinic to define the
parties’ responsibilities, detail the cost of recovered heat, and authorize the connection to the power
plant heat recovery equipment.
Preliminary Equipment Selections:
Heat recovery Piping:
The length of heat recovery piping to all buildings totals approximately 6400 feet round trip. The size is 1-
1/2” to 4” carrier pipe depending on the flow rate. The size was selected to provide sufficient velocity for
purging air from the pipes while keeping pressure drop to a minimum to reduce pumping energy.
The pipe itself consist of a PEX carrier pipe with O2 barrier, foam insulation and an HDPE outer jacket.
The specified product is suitable and durable enough for direct bury applications.

Cost Estimate and Payback:
Estimated construction costs were determined based on prior recent heat recovery project experience,
and include materials, equipment, freight, labor, design, construction management, startup & testing.
All work at the power plant and end users, along with design and construction management /
administration for the complete project, is included in the project cost. Refer to the attached cost
estimate for specifics.
The estimated project cost is about 3 million, which includes 9% price escalation before start of
construction. Estimated fuel savings are about 52,100 gallons annually. Using a 2022 fuel price of $6.27
/ gal diesel results in estimated community savings of $321,000 annually. Typical fuel price escalation
is approximately 1.5% / Year above inflation, which generates a total savings over the life of the project
of $14.3 million. O&M is estimated to be approximately 1% of the direct construction cost (not
including engineering, PM services, etc) and is expected to grow at the rate of inflation (3% / year). The
below table summarizes cost and payback for the project:
Construction Cost Including Design $3.07 million
Avoided Fuel Costs over life of project $14.3 million
O&M costs over life of project $693 thousand
Net avoided cost over life of project $13.6 Million
Discounted Benefit / Cost ratio (including O&M) 4.4
Conclusion
The city of Yakutat has enjoyed free heat from the existing heat recovery system for almost three decades
to their three school buildings and the police station, saving them roughly $239,000 a year at today’s fuel
costs. There is additional heat to add the clinic if the system is replaced and expanded. The current
system condition is unsustainable. Without immediate replacement, the failure of the existing heat
recovery system will create an environment for the city of Yakutat that will force the closures of all school
buildings, since they have no back up heating source. With 55 gallons leaking out of the 27 year old
distribution loop every ten days and now replaced with unfiltered water instead of the proper heat
carrying fluid, this system is going to fail within the next couple of years, if not this winter.
The cost of replacing and expanding this system is about 3 million dollars, which will save $327,200
annually in fuel costs at 2022 prices. The construction cost is not exact, as more detailed calculations from
cost estimators would need to be made, and were not under the scope of this study. Assuming 1.5%
annual fuel cost increase above inflation and 3% growth annually in O&M costs, the system will save $13.6
million over its lifetime for a benefit / cost ratio of 4.4. The value of the schools staying open is
incalculable.
It is recommended that the city seek funding to provide backup heating infrastructure to their three school
buildings, in the event of a power loss. It is recommended that the existing heat recovery system be
replaced as soon as possible with the addition of the health clinic.

MEMORANDUM
TO: Yekaterina Karankevich
FROM: Will Fraser, P.E. Lead Mechanical Engineer
ANTHC-Division of Environmental Health & Engineering SUBJECT: Yakutat Health Clinic Recovered Heat Cost and Payback
DATE: November 10, 2022
Introduction:
This memo explores the potential cost / benefit of recovering heat from the Yakutat power plant
cooling system and using it to heat the new Yakutat Health Center. This would offset approximately 18,400 gallons of heating fuel currently used by the clinic. The economic savings
of this avoided fuel use would be used to create a heat recovery replacement fund and go to
expand preventative services for the clinic.
Yakutat Clinic Fuel Consumption Estimate:
Yakutat Clinic fuel consumption data was collected between September 2020 and April 2022,
with a calculated annual consumption during this time period of 17,119 gallons / year. This data was used to estimate fuel consumption per heating degree day and calculate a typical year fuel consumption of 18,400 gals of heating fuel per year. This could fluctuate up or down annually
due to variations in outside temperature, but is a good baseline estimate for annual average fuel consumption.
Available Recovered Heat at the Yakutat Power Plant:
Yakutat’s power plant currently employs heat recovery which is distributed to the Yakutat High
School and Elementary school, as well as the vocational shop, public safety building, and housing for the power plant maintenance workers. This heat is provided at no cost due to a pre-existing agreement established when the power plant was sold to the power plant operator
(AVEC). The heating load from the connected buildings create a peak load of approximately 580 MBH. The Clinic adds an additional 332 MBH peak load for a total combined peak load of 912 MBH. The summary of fuel use per building is below:
AEA - 23046 Page 59 of 104
2
Facility Annual Fuel Use
High School 19,531 Gallons
Elementary School 6,088 Gallons
Wood Shop 3,554 Gallons
Public Safety Building 3,615 Gallons
AVEC housing 988 Gallons
Clinic 18,408 Gallons
Total: 52,183 Gallons
Based on analysis of the power production from the generators and the produced heat sent to
the radiators, the existing power plant is fully capable of delivering between 1,021 to 1,381 MBH of recovered heat after line losses are subtracted, so there is sufficient capacity to fully meet the
existing heat recovery demand as well as fully serve the new clinic with a new heat recovery
system.
However, the existing 27 year old heat recovery system is in poor shape, leaking badly, and in
eminent danger of failing. It is past its useful design life and not capable of meeting the existing load or the clinic load in its current condition. Most of the problems with the existing system are
in the distribution piping and at the end user buildings. Partial funding has been granted to
replace the system for the school and public safety office from the Helmsley Charitable Trust.
Cost of Extending Recovered Heat to the Clinic:
This memo assumes connecting recovered heat to the clinic is a standalone project executed
independently of replacement of the existing heat recovery distribution system. While there is some overlap of work between the two projects at the Power plant, the majority of work to provide recovered heat to the clinic is running buried heat recovery lines to the clinic and
modifying the boiler system at the clinic to accommodate recovered heat, and it is not unreasonable to treat the clinic project and refurbishment / replacement of the existing heat recovery system as separate projects. Based on that presumption, the cost to extend the heat
recovery system to the clinic is $1,273,000 per the attached cost estimate. Note that
construction costs are highly variable at this time with procurement delays and high inflation adding significant uncertainty to projected costs.
Additionally, the heat recovery system will require maintenance, which is estimated to be approximately $3,500 annually at 2022 prices. The Clinic has agreed to own the system and
pay for maintenance along with an annual savings fund for future replacement.

Economic savings of recovered heat to the Clinic:
As of May 2022, fuel oil in Yakutat was $6.27 / gal, which represents an annual savings to the
Clinic of $111,915 / year in 2022 dollars after maintenance costs are subtracted. In terms of simple payback, the system will cover construction and maintenance costs in 11.4 years.
Given current volatility in fuel prices, it’s impossible to say with certainty what the economic
savings are going to be over the 25 year life expectancy of the system. However, it is likely that efforts to reduce global warming, as well as shifting geopolitical alliances, will lead to fuel price
inflation above annual inflation. This is included in the below projected fuel savings as a 1.5% surcharge above the rate of inflation, which is projected to run in the range of 3% average for the next 25 years. Over the anticipated 25 year life of the system, this is a cumulative savings
(after O&M costs) of $5.016 million.

RE: Letter of Support from the Alaska Native Tribal Health Consortium (ANTHC) for the
Yakutat Tlingit Tribe’s Application to the Alaska Energy Authority (AEA) Renewable Energy
Fund (REF), Round 15 grant opportunity
To Whom It May Concern,
Please accept this Letter of Support from the ANTHC for the Yakutat Tlingit Tribe (YTT)’s
application for the Alaska Energy Authority (AEA) Renewable Energy Fund (REF), Round 15
grant opportunity. If awarded, the funds will be used to complete the construction of the heat
recovery system for Yakutat’s community health center.
As part of ANTHC’s Division of Environmental Health and Engineering (DEHE), the Rural
Energy Program works with communities to make public health services more affordable
through diverse energy projects. Energy costs in rural communities across Alaska often pose
challenges to local governments responsible for maintaining public infrastructure. This project
will directly benefit Tribal Health Facilities in Yakutat, resulting in an overall reduction in
energy costs for the Alaska Tribal Health System in Yakutat and the community members YTT’s
health clinic serves. Energy costs in rural Alaska specifically impact the Alaska Native and
American Indian people ANTHC. This application’s proposed work is substantially aligned with
ANTHC’s vision that “Alaska Native people are the healthiest people in the world,” directly
working towards its mission of “providing the highest quality health services in partnership with
our people and the Alaska Tribal Health System.”
ANTHC and YTT have supported one another and partnered together in pursuit of this vision
throughout the community and ANTHC’s history. If Yakutat is awarded funding under this
proposal, ANTHC’s Rural Energy Program is committed to providing comprehensive project
management services to the community through a Cooperative Project Agreement, to be created
in cooperation with YTT upon notification that their application has been recommended for
funding by AEA. The ANTHC Rural Energy Program has worked diligently with Yakutat and
YTT to assist in the development of this application and anticipates working closely with the
community to achieve the project objectives outlined by the application.

SUBJECT: Population Projections 2021 through 2039, Yakutat Alaska. Utilities Preliminary
Engineering Analysis
This report is delivered as part of the Utilities Preliminary Engineering Analysis project. The results and
draft report have been reviewed by the YCHC Leadership Team. Results of this report may be utilized for
population projections for purposes of future housing and utility needs. Data in this report reflects
residential population and excludes seasonal variations from migration, commercial and sport fishing, or
other factors which may impose a temporary increase in population.
Several sources were reviewed in order to determine Yakutat’s population. The majority of them use the
US Census data and projection models. Although the US Census is the prevailing and official population
data, it is only collected and published every 10-years. Yakutat’s population is small enough that even
minor adjustments have significant impacts that can be easily masked without supplemental data.
The most complete data comes from the State of Alaska Department of Labor and Workforce
Development-Research and Analysis. This data is collected and reported annually. 2020 Census Data for
Redistricting and, Cities and Census Designated Places 2010 to 2020 is available on the State’s web-site.
The State of Alaska collects information from the Alaska PDF for the database. Assuming the population
are Alaskan residents and they applied for their Permanent Fund Dividend; the margin of error is likely
very small. The data from 2010 through 2020 is listed in Table 1 below.
AEA - 23046 Page 102 of 104
Table 1: 10-year Historical Population
The data shows zero growth rate between 2010 and 2020 based on the US Census Bureau data. What is
doesn’t reveal is the trend during this period. When supplemented with data from the State of Alaska,
the population shows a steady decrease between 2010 and 2017 (with 2014 being the acceptation with
a population increase of 5). It also shows a steady increase between 2017 and 2020.
The total population increase between 2017 to 2020 is 118. This is an increase of 21.7% or 5.03%
annually. This trend has been empirically observed. However, the magnitude of the increased has not
been tracked or reported since the 2020 Census Data was published.
The reversing trend is good to see for Yakutat. But, the annual rate 5.03% is unlikely sustainable for
long-range planning. For the purposes of the Utility Preliminary Engineering Analysis projects for a 20-
year horizon, we are recommending an annual growth rate of 2.5%. This results in a design population
of 1058 in the year 2039. The results are summarized in Table 2 as shown below.

Note that these numbers reflect the year-round residential population for Yakutat and excludes
seasonal migration or fluctuations due to commercial or sport fishing and other variations in
populations. These numbers may be used in strategizing for housing demands and planning. Planning for
the demands on utility infrastructure will include assessment of seasonal fluctuations and commercial or
industry demands. These will be included in future tasks under this Work Order Project.
