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

Purchaser shall be responsible for maintaining that portion of the heat recovery system on the
Purchaser’s side of the delivery point and AVEC shall be responsible for maintaining that portion of
the heat recovery system on AVEC’s side of the delivery point. All maintenance of the system
inside Provider’s facility shall be coordinated with AVEC.
If the Purchaser fails to properly maintain the system in a fully functioning and environmentally safe
manner, AVEC shall have the right to take corrective actions and recover its costs from the
Purchaser. Except in the case where a failure to maintain may imminently threaten life or property,
AVEC shall give reasonable notice in writing to the Purchaser of its intention to take corrective
action under this paragraph, including an estimate of recoverable costs.
Purchaser’s payment obligation described in this section to Provider shall start on the first day of
the second month after the Operational Date and remain in effect through the term of the heat
sales agreement.
No invoice will be issued by AVEC. Billing will be provided on the Purchaser's monthly electric bill.
Purchaser shall pay a sum equal to the agreed amount each month no later than the 25th of each
month.
All amounts not paid by the date due shall accrue interest at the rate of one percent (1.0%) per
month. In addition, in the event Purchaser fails to pay any amount due to Provider, Provider
reserves the right to discontinue the supply of heat. Provider will notify Purchaser in writing if the
supply of heat is being discontinued for nonpayment and, if within thirty (30) days after receipt of
notification Purchaser fails to pay the balance due, heat may be discontinued without further
notice.
Provider retains the right to sell additional Recovered Heat to other entities. If the sale of additional
Recovered Heat will not significantly reduce the amount of Recovered Heat available under the
heat sales agreement (less than 20% reduction), AVEC shall issue written notice to the Purchaser
of the intent to sell additional Recovered Heat prior to commencing delivery of additional
Recovered Heat. If the sale of additional Recovered Heat will significantly reduce the amount of
Recovered Heat available under the heat sales agreement (greater than 20% reduction), AVEC
shall issue written notice to the Purchaser of the intent to sell additional Recovered Heat a
minimum of 6 months prior to commencing delivery of additional Recovered Heat.

5.4.2 Future Trends
Describe the anticipated energy demand in the community over the life of the project.
Assuming population remains the same or populations grow, the demand for heat in the water
treatment plant processes will always be present. Thus the energy demand for this application will
either be steady or increase.
5.4.3 Impact on Rates
Briefly explain what if any effect your project will have on electrical rates in the proposed benefit
area over the life of the project. For PCE eligible communities, please describe the expected
impact would be for both pre and post PCE.
This project is anticipated to reduce fuel consumption up to 9,726 gallons per year. This project is
not intended to have an impact on electrical rates or PCE.
However, with the reduced cost of heat in the processes of providing water, utility rates should see
a decrease.
5.4.4 Proposed System Design
Provide the following information for the proposed renewable energy system:
A description of renewable energy technology specific to project location
Optimum installed capacity
Anticipated capacity factor
Anticipated annual generation
Anticipated barriers
Integration plan
Delivery methods
The heat recovery system captures jacket water heat generated by the generators at the AVEC
power plant that is typically rejected to the atmosphere through radiators. The recovered heat is
transferred through arctic piping to the end users. The objective is to reduce the consumption of
heating fuel by utilizing available recovered heat.
The proposed system will transfer heat from the jacket water cooling systems of the generators in
the AVEC power plant to the systems in the water treatment plant (WTP). The heat recovery
pipeline will consist of 400 linear feet of 3 inch polypropylene and fiberglass composite and
composite carrier pipe insulated with 3.5” of polyurethane foam insulation win an HDPE outer
jacket. 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 the mixing fluids. Controls
at the power plant are used to prevent sub-cooling of the generator engines and reductions in
electric power production efficiency. The recovered heat fluid is pumped through buried insulated
pipe to the adjacent Water Plant and Washeteria, and typically is tied into the end user heating
system using a brazed plate heat exchanger. New equipment including a heat exchanger,
expansion tank and glycol tank will be installed at the AVEC power plant; and new heat
exchangers and pumps will be installed at the WTP.
POWER PLANT TIE-IN
Renewable Energy Fund Round IX
Grant Application – Heat Projects
AEA 16012 Page 20 of 29 7/8/15
Modifications to the AVEC power plant include retrofitting the existing generator with a marine
jacket, installation of heat exchangers, control valves, and associated piping and plumbing.
The AVEC plant cooling system will be separated from the recovered heat system with an injection
pump, heat exchanger and controls designed to maintain minimum generator operating
temperature and provide physical isolation of the two systems. The methodology will follow the
standard approach favored by AVEC. All heat recovery piping at the AVEC facility will be insulated
with a minimum of 2-in insulation and have an aluminum jacket where exposed to the weather. All
valves will be either bronze ball valves or lug style butterfly valves with seals compatible with 50/50
glycol/water mixtures at 200F. Air vents, thermometers, pressure gauges, drain valves, and
pressure relief valves will also be provided. In addition, a marine manifold will be retrofitted to the
DD series 60 genset. Additional controls will be added, including a BTU meter and motorized
bypass valve for coolant temperature control.
The recovered heat fluid will be a 50/50 propylene glycol/water solution to provide freeze protection
to the piping.
WATER TREATMENT PLANT TIE-IN
The WTP tie in will consist of a VFD circulation pump to move heat from the power plant to the
WTP, a brazed plate heat exchanger and a separate pump to inject heat into the WTP heating
system designed to avoid introducing excessive pressure drop in the building heating system. The
maximum anticipated delivered recovered heat supply temperature is about 180F. When there is
insufficient recovered heat to meet the building heating load, the building heating system (boiler or
heater) will fire and add heat. Off the shelf controls will lock out the recovered heat system when
there is insufficient recovered heat available.
Typical indoor piping will be type L copper tube with solder joints. Isolation valves will be solder
end bronze ball valves or flanged butterfly valves. All piping will be insulated with a minimum of 1-
in 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 also be provided.

SECTION 6 – ECONOMIC FEASIBILITY AND BENEFITS
6.1 Economic Feasibility
Criteria: Stage 2-4.A: The project is shown to be economically feasible (net positive savings in fuel,
operation and maintenance, and capital costs over the life of the proposed project).
6.1.1 Economic Benefit
Explain the economic benefits of your project. Include direct cost savings, and how the people of
Alaska will benefit from the project. The benefits information should include the following:
Anticipated annual and lifetime fuel displacement (gallons and dollars)
Anticipated annual and lifetime revenue (based on i.e. a Proposed Power Purchase Agreement
price, RCA tariff, or cost based rate)
Additional incentives (i.e. tax credits)
Additional revenue streams (i.e. green tag sales or other renewable energy subsidies or
programs that might be available)
The economic model used by AEA is available at
http://www.akenergyauthority.org/Programs/Renewable-Energy-Fund/Rounds#round9. This
economic model may be used by applicants but is not required. The final benefit/cost ratio used
will be derived from the AEA model to ensure a level playing field for all applicants. If used, please
submit the model with the application.
Based on the attached 2015 Wales, Alaska Heat Recovery Study, this project will save 9,726
gallons or $ 38,223 annually. By reducing this cost, the money normally spent on heating oil can
stay in the local economy.
The potential fuel displacement is 9,726 gallons of the 11,238 gallons of fuel to be used by the
water system. The cost of the fuel is $ 3.93 per gallon. This cost is based on a 2014 price for fuel
to the community. The community did not purchase fuel in 2015. The annual cost of fuel displaced
for the water treatment plant therefore equals $ 38,223.
There are no other known incentives or revenue streams that will result from this project. The
benefits to the community of this project include a reduction in the amount of fuel required by the
community, more efficient use of the recovered engine heat, and a direct benefit to each
community member due to the lower cost to produce, store, and deliver water.
Assuming a lifetime of 20 years, diesel fuel displacement would be 194,520, with total avoided C02
emissions of 1,972 tonnes.
6.1.2 Power Purchase/Sale
The power purchase/sale information should include the following:
Identification of potential power buyer(s)/customer(s)
Potential power purchase/sales price - at a minimum indicate a price range
Proposed rate of return from grant-funded project
Identify the potential power buyer(s)/customer(s) and anticipated power purchase/sales price
range. Indicate the proposed rate of return from the grant-funded project.
A standard heat sales agreement will be executed between AVEC and the City of Wales. The
agreement will define the terms and methods for heat sales. Typically, heat sales agreements
charge end users the equivalent of one third the electric utility price of fuel displaced. This amount
is much lower than the retail price of fuel in the village.
Renewable Energy Fund Round IX
Grant Application – Heat Projects
AEA 16012 Page 23 of 29 7/8/15
In Wales, the 2015 fuel price for AVEC is $3.34. This would mean that AVEC would receive from
the City of Wales an annual payment of $9,745 based on 30% of $3.34 multiplied by the expected
avoided fuel use of 9726 gallons of fuel at the Washeteria. .
6.1.3 Public Benefit for Projects with Private Sector Sales
For projects that include sales of power to private sector businesses (sawmills, cruise ships, mines,
etc.), please provide a brief description of the direct and indirect public benefits derived from the
project as well as the private sector benefits and complete the table below. See section 1.6 in the
Request for Applications for more information.
Based on the attached 2015 Wales, Alaska Heat Recovery Study, this project will lower energy
consumption by 9,726 gallons of heating oil annually.
By offsetting the fuel costs related to providing heat to the city’s water treatment plant, the users of
the utility who pay for water service should see a reduction in local utility costs. This bill reduction
would affect all users who pay fees to the local utility company.
There are no other known incentives or revenue streams that will result from this project. The
benefits to the community of this project include a reduction in the amount of fuel required by the
community, much more efficient use of the recovered engine heat, and a direct benefit to each
community member due to the lower cost to produce, store, and deliver water.
Renewable energy resource availability (kWh per month)
Estimated sales (kWh)
Revenue for displacing diesel generation for use at private sector businesses ($)
Estimated sales (kWh)
Revenue for displacing diesel generation for use by the Alaskan public ($)
6.2 Financing Plan
Criteria: Stage 2-4.B: The project has an adequate financing plan for completion of the grant-
funded phase and has considered options for financing subsequent phases of the project.
6.2.1 Additional Funds
Identify the source and amount of all additional funds needed to complete the work in the phase(s)
for which REF funding is being applied in this application. Indicate whether these funds are
secured or pending future approvals. Describe the impact, if any, that the timing of additional
funds would have on the ability to proceed with the grant.
There are not additional funds needed to complete the work as currently identified.
6.2.2 Financing opportunities/limitations
If the proposed project includes final design or construction phases, what are your opportunities
and/or limitations to fund this project with a loan, bonds, or other financing options?
The community is not interested in applying for financing for this project at this time.
6.2.2 Cost Overruns
Describe the plan to cover potential cost increases or shortfalls in funding.
ANTHC will make every effort to keep the project within the budget. In previous instances where
there were project overruns, ANTHC has successfully tapped into other funding opportunities to
make up the budget deficits. This would be the approach for this project as well.
Renewable Energy Fund Round IX
Grant Application – Heat Projects
AEA 16012 Page 24 of 29 7/8/15
6.2.3 Subsequent Phases
If subsequent phases are required beyond the phases being applied for in this application,
describe the anticipated sources of funding and the likelihood of receipt of those funds.
There are no further phases for this project, beyond what is being applied for in this application.
6.3 Other Public Benefit
Criteria: Stage 3-4.C: Other benefits to the Alaska public are demonstrated. Avoided costs alone
will not be presumed to be in the best interest of the public.
Describe the non-economic public benefits to Alaskans over the lifetime of the project. For the
purpose of evaluating this criterion, public benefits are those benefits that would be considered
unique to a given project and not generic to any renewable resource. For example, decreased
greenhouse gas emission, stable pricing of fuel source, won’t be considered under this category.
Some examples of other public benefits include:
The project will result in developing infrastructure (roads, trails, 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
The recovered heat from the power plant could be utilized as an alternative heat source for the
sanitation system which will drive down user fees in the community, increasing affordability of safe
drinking water and piped sewer. Cost savings to users will provide access to these systems and
allow reserves to accumulate to address operations and maintenance issues of the larger
sanitation system as a whole. As you can see in the community’s use of community revenue
sharing attached to this application, the Washeteria is heavily subsidized. If community revenue
sharing were to be eliminated in the future, the health of the entire community could be jeopardized
by the high costs of providing water and sewer services.
There are positive health impacts associated with providing water and sewer to homes including
reduced occurrence of respiratory illness and other diseases. Reducing water user costs will
increase access to these services and improve the health of the community.

AEA 16012 Page 25 of 29 7/8/15
SECTION 7 – SUSTAINABILITY
Describe your plan for operating the completed project so that it will be sustainable throughout its
economic life.
Include at a minimum:
Capability of the Applicant to demonstrate the capacity, both administratively and financially, to
provide for the long-term operation and maintenance of the proposed project
Is the Applicant current on all loans and required reporting to state and federal agencies?
Likelihood of the resource being available over the life of the project
Likelihood of a sufficient market for energy produced over the life of the project
This project increases the sustainability of the water system by reducing its operating cost over the
life of the project. The minimal maintenance and operating cost can be funded out of its revenue
stream from supplying water and laundry services and out of its savings over the 20-year life of the
project.
Although the boilers will be maintained and are the primary heating source in the water treatment
plant, their use is to be greatly curtailed. The City of Wales is committed to meeting all reporting
requirements over the entire length of the reporting period.
Due to limited funding availability and high infrastructure costs and a small population, it is unlikely
that the Washeteria and Water Plant in Wales will be replaced with a piped water and sewer
system in the near future.
SECTION 8 – PROJECT READINESS
Describe what you have done to prepare for this award and how quickly you intend to proceed with
work once your grant is approved.

EXECUTIVE SUMMARY
The existing Wales power plant and future Water Treatment Plant / Washeteria (WTP) were
evaluated for heat recovery potential. The total estimated annual heating fuel used is
estimated to be approximately 11,238gallons. Heat recovery is expected reduce the fuel
consumed by 9,726 gallons. The expected annual total fuel savings is $38,223
The payback is based on a 2015 fuel price of $3.93/gallon and an estimated 2015 project cost
of $656,613. The payback time is 16.19 years
Assuming construction of the heat recovery system in 2017, the design and construction cost
with 2 years of 3% escalation is $656,613.
1.0 INTRODUCTION
The Alaska Native Tribal Health Consortium (ANTHC) reviewed the feasibility of providing
recovered heat from the Wales power plant to the refurbished WTP in Wales. ANTHC also
developed a budgetary project cost estimate based on Force Account Construction, including
Engineering and Construction Administration.
The refurbished WTP also serves as the community washeteria and will provide heat to the
circulating water lines serving nearby public buildings and heat to the community Water
Storage Tank (WST).
This report assumes that space for heat recovery equipment at the power plant will be
available, with necessary controls, pumps and heat exchangers added as part of
modifications to the existing building.
Additional assumptions have been made in the development of this report, including, but not
limited to, the proposed arctic piping route, building heating loads and flow rates and pressure
drops of the power plant heat recovery system. It is anticipated that refinements in arctic pipe
size and routing, pump and heat exchanger sizing, and other design elements will be required
as the project progresses to final design.
Available as-built information of the power plant was obtained from AVEC. Recovered heat
availability is based on the 2014 power plant electrical loads. End-user annual fuel use was
obtained from a variety of sources, including the City, Village Safe Water, and engineering
estimates. Where possible, reported fuel consumption was used to validate engineering
estimates.
2.0 OVERVIEW
The purpose of this study is to provide an estimate of the heat that can be recovered from the
AVEC power plant diesel engines and used to offset heating oil consumption at the nearby
water plant / Washeteria (WTP). Useable recovered heat is quantified in gallons of heating
fuel saved using a gross heating value of 134,000 BTU per gallon of #1 arctic diesel fuel and
an overall boiler efficiency of 80% for a net heating value of 107,000 BTU per gallon.
The existing WTP being refurbished is located within 200 feet of the AVEC power plant. The
estimated average annual heating fuel consumption for the nearby WTP is 11,238 gallons.
3.0 ESTIMATED RECOVERED HEAT UTILIZATION
A heat recovery utilization spreadsheet has been developed to estimate the recoverable heat
based on monthly total electric power production, engine heat rates, building heating
demand, washeteria loads, heating degree days, passive losses for power plant heat and
piping, and arctic piping losses. Power generation data from AVEC for fiscal year 2014 is
used in the spreadsheet.
The estimated heat rejection rates for the power plant gensets, A Detroit Diesel series 60 with
marine jacket and two Cummins CMS LTA 10 , were used to estimate available recovered
heat. Heating degree-days for Wales were utilized for this site. All arctic piping is assumed to
be routed below grade. All power plant hydronic piping is assumed to be insulated with 2
inches of insulation. Past experience was used for estimating the heating load for the power
plant, which includes the power house, an insulated storage module, and one living quarters
module.
The spreadsheet uses monthly heating degree-days to distribute annual fuel consumption by
month. The end-user hourly heat load is compared to the hourly available heat from the
power plant, less power plant heating loads and parasitic piping losses, and the net delivered
heat to the end-user is determined.
Following is a summary of annual fuel use and estimated heat utilization in equivalent gallons
of fuel for the water plant:

4.0 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. The recovered heat is transferred
via below-grade arctic piping to the end user. The objective 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.
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 subcooling of the generator engines which
would reduce electric power production efficiency. The recovered heat fluid is pumped
through buried insulated pipe to the end-user, and is tied into the end-user heating system
using a plate heat exchanger.
4.1 AVEC PLANT TIE-IN
The AVEC plant cooling system will be separated from the recovered heat system with an
injection pump, heat exchanger and controls designed to maintain minimum generator
operating temperature and provide physical isolation of the two systems. The methodology
will follow the standard approach favored by AVEC.
All heat recovery piping at the AVEC facility will be insulated with a minimum of -in insulation
and have an aluminum jacket where exposed to the weather. All valves will be either bronze
ball valves or lug style butterfly valves with seals compatible with 50/50 glycol/water mixtures
at 200F. Air vents, thermometers, pressure gauges, drain valves, and pressure relief valves
will also be provided.
4.2 ARCTIC PIPING (Recovered Heat Loop)
The proposed arctic piping is based on a manufactured pre-insulated buriedaquatherm pipe
system with minimum of 1-1/2-in polyurethane foam insulation and HDPE outer jacket. The
piping will be buried approximately 2 ft deep and run from the AVEC plant within existing
rights-of-way to the end-user water treatment plant.
The recovered heat fluid will be a 50/50 Propylene Glycol/Water solution to provide freeze
protection to the piping.
4.3 WATER TREATMENT PLANT TIE-IN
The WTP tie in will consist of a VFD circulation pump to move heat from the power plant to the
WTP, a brazed plate heat exchanger and a separate pump to inject heat into the WTP heating
system designed to avoid introducing excessive pressure drop in the building heating system.
The maximum anticipated delivered recovered heat supply temperature is about 180F. When
there is insufficient recovered heat to meet the building heating load, the building heating
system (boiler or heater) will fire and add heat. Off the shelf controls will lock out the
recovered heat system when there is insufficient recovered heat available.
Typical indoor piping will be type L copper tube with solder joints. Isolation valves will be
solder end bronze ball valves or flanged butterfly valves. All piping will be insulated with a
minimum of 1-in 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 also be provided.
4.4 RIGHTS-OF-WAY ISSUES
There are no apparent conflicts with rights-of-ways for the arctic piping between the power
plant and the water treatment plant, as the route is entirely within existing road rights-of-ways
and on city and AVEC property.
A Heat Sales/Right-of-Entry Agreement will be required between AVEC and the end users to
define the parties’ responsibilities, detail the cost of recovered heat, and authorize the
connection to the power plant heat recovery equipment.
4.1 POTENTIAL RISKS AND UNKNOWNS
Incorporation of wind turbines to reduce generator power consumption would most likely
reduce the amount of recovered heat available, though if marine jacketed engines are used,
there is still likely to be sufficient recovered heat available to provide a benefit for the facility
proposed in this study.
5.0 PRELIMINARY EQUIPMENT SELECTIONS
The following initial equipment selections are sized and selected based on preliminary data
and will require minor modifications to reflect final design.
5.1 Heat Exchangers
Based on initial selected flow rates, brazed plate heat exchangers appear to be adequate for
all locations. Initial heat exchanger selections are as follows.
HX-1: (Power Plant). 150 MBH capacity

Secondary: 22 GPM 175F LWT (50% propylene glycol) 1.5 PSI max WPD
5.2 Arctic Piping
The round trip length of heat recovery loop piping between the power plant and the WTP is
approximately 400 ft. The pipe consists of a 2-in PEX carrier pipe with minimum of 1-1/2-in
polyurethane foam insulation and an HDPE outer jacket. The specified product is durable
enough for direct bury. The piping and excavated soil will be will be wrapped in geotextile
fabric to hold the pipe in the ground in the event of flooding.

plant heat exchanger will be 45 PSIG and the maximum normal operating pressure will be 30
PSIG.
ET-1: System requirements: 15 gallon tank and 15 gallon acceptance
5.5 GLYCOL MAKEUP
A glycol make-up system at the WTP will be provided to accommodate filling the system and
adding additional glycol.
GT-1: Select AXIOM 10 Gal Glycol make-up tank.
5.6 CONTROLS
Heat recovery system in the WTP will use an off the shelf differential temperature controller to
start/stop heat injection pump. Additional controller will look at the differential temperature
across the heat exchanger and modulate the heat recovery circulation pump to minimize
energy consumption. Controls will provide load shedding, freeze protection, and prevent back
feeding of boiler heat into heat recovery system. In addition, btu’s delivered will be metered
utilizing the PLC at the AVEC power plant, with a flow meter and thermometer.
Differential Controllers: Honeywell 755 differential temperature control and integrated
temperature controller built into variable speed pump.
6.0 CONCLUSIONS AND RECOMMENDATIONS
Estimated construction costs were determined based on prior recent heat recovery project
experience, and include materials, equipment, freight, labor, design, construction
management, and startup and testing. All work at the power plant and WTP, along with
design and construction management/administration for the complete project, is included in
the Base Project cost. (Refer to attached cost estimate).
The estimated project cost is $618,921. Estimated fuel savings are:
9,726 gallons ($38,223) for a simple payback of 16.19 years.
Payback is based on a 2015 fuel price of $3.93/gallon. Funding for design and construction
isn’t expected before fall 2016, with construction occurring summer of 2017.
With 2 years of escalation at 3%, the estimated project cost in 2017 is $656,613.

This will help to reduce move in , move out as well are seperate equipment renting cost. If this project is built before or after water treatment /washateria project then new cost estimate is required. Based on limited need for equipment, this is not a significant risk to this project and can be accounted for in the given contingency.
