SECTION 4 — PROJECT DESCRIPTION AND TASKS
• The level of information will vary according to phase(s) of the project you propose to
undertake with grant funds.
• If some work has already been completed on your project and you are requesting funding for
an advanced phase, submit information sufficient to demonstrate that the preceding phases
are satisfied and funding for an advanced phase is warranted.
4.1 Proposed Energy Resource
Describe the potential extent/amount of the energy resource that is available.
Discuss the pros and cons of your proposed energy resource vs. other alternatives that may be
available for the market to be served by your project. 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.
The energy resource available is the heat from the water jackets of the power plant engines. The
heat available from the power plant can greatly offset the energy required by the combined utility
building and washeteria, as indicated by the attached 2012 Heat Recovery Feasibility Study.
4.2 Existing Energy System
4.2.1 Basic configuration of Existing Energy System
Briefly discuss the basic configuration of the existing energy system. Include information about
the number, size, age, efficiency, and type of generation.
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. The spreadsheet utilizes assumed time -of -day variations for electric power
production and heat demand. Power generation data from AVEC for fiscal year 2011 is used in
the spreadsheet. The estimated heat rejection rate for the lead power plant genset, a Detroit
Diesel Series 60 DDEC4, is used to estimate available recovered heat. Heating degree-days for
Kwinhagak were utilized for this site. All arctic piping is assumed to be routed above grade. All
exterior power plant hydronic piping is 3- or 4-in pipe. The analysis includes 1-1/2" of insulation
to be installed as part of this project.
4.2.2 Existing Energy Resources Used
Briefly discuss your understanding of the existing energy resources. Include a brief discussion of
any impact the project may have on existing energy infrastructure and resources.
The washeteria commercial heating loads are field verified as approximately 80% of maximum
utilization for 8 hours a day„ 5 days a week. 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, to determine the net delivered heat to the end user.

4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
Heating oil must be barged in during the summer months. The impact of this project will be to
reduce the overall use of oil by approximately 14,200 gallons per year. While this reduction will
not change the price of oil in Kwinhagak, it will significantly reduce the community's consumption
of oil, replacing that consumption with jacket heat from the diesel engines and, potentially,
excess wind energy in the future.
4.3 Proposed System
Include information necessary to describe the system you are intending to develop and address
potential system design, land ownership, permits, and environmental issues.
4.3.1 System Design
Provide the following information for the proposed renewable energy system:
• A description of renewable energy technology specific to project location
• Optimum installed capacity
• Anticipated capacity factor
• Anticipated annual generation
• Anticipated barriers
• Basic integration concept
•_ Delivery methods
The 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
above -grade arctic piping to the end users. 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 sub -cooling of the generator engines and reducing electric
power production efficiency. The recovered heat fluid is pumped through 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
AEA13-006 Grant Application
Page 8 of 20
7/3//2012
Renewable Energy Fund Round 6®
Grant Application ®ENERGYAUTHORMY
Marine Jackets will be added to the AVEC Generators to increase the available recovered heat.
If practical, an electric boiler will be added to pick up excess wind capacity when available. All
heat recovery piping will be insulated with a minimum of 1.5-in rubber foam 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. Additional controls will be added, including a BTU meter and motorized bypass valve
for coolant temperature control.
ARCTIC PIPING (Recovered Heat Loop)
The proposed arctic piping is based on ANTHC's standard arctic pipe design with a 3-inch fiber
reinforced polypropylene carrier pipe (Aquatherm Climatherm SDR11), 4-inch polyurethane foam
insulation, and aluminum outer jacket. The piping will be supported on sleepers on the ground
surface or helical piers where the ground isn't sufficiently stable. The heat recovery piping will
run from the power plant alongside the road to the abandoned sewer lagoon to the end -user
buildings.
Because multiple users are connected to the system, circulation pumps located at the
washeteria and combined utility building will circulate heating fluid to each user from the AVEC
facility. When users are not actively consuming recovered heat, their systems will throttle down
heating fluid flow to minimize power consumption.
The recovered heat fluid will be a 50/50 Propylene Glycol/Water solution to provide freeze
protection to the piping.
END -USER BUILDING TIE-INS
End -user building tie-ins typically consist of brazed plate heat exchangers with motorized bypass
valves or heat injection pumps to prevent back feeding heat to AVEC or other users. Plate heat
exchangers located in the end -user mechanical rooms will be tied into the boiler return piping to
preheat the boiler water prior to entering the boiler. Where required, a heat injection pump will be
used instead of a motorized bypass valve to avoid introducing excessive pressure drop in the
building heating system. The maximum anticipated delivered recovered heat supply temperature
is about 190F. 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-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 also be provided.
Each facility will also receive a BTU meter to provide recovered heat use totalization and
instantaneous use.
PRIORITIZATION OF RECOVERED HEAT
Recovered heat prioritization is accomplished by setting the minimum recovered heat
temperature for each 'user, with successive load shedding as the recovered heat loop
temperature falls. The user with the highest allowable recovered heat temperature will be
removed from the system first. The user with the lowest allowable recovered heat temperature
will be removed from the system last.
_The system will also provide freeze protection in the event a user's boiler system temperature

falls below a minimum temperature, typically 50-100 degrees F,
4.3.2 Land Ownership
Identify potential land ownership issues, including whether site owners have agreed to the
project or how you intend to approach land ownership and access issues.
There are no apparent conflicts with right-of-ways for the arctic piping between the power plant
and the end -user buildings, as the route is entirely within existing road right-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.
4.3.3 Permits
Provide the following information as it may relate to permitting and how you intend to address
outstanding permit issues.
• List of applicable permits
• Anticipated permitting timeline
• Identify and discussion of potential barriers
No permits are anticipated for this heat recovery project.
4.3.4 Environmental
Address whether the following environmental and land use issues apply, and if so how they will
be addressed:
• Threatened or Endangered species
• Habitat issues
• Wetlands and other protected areas
• Archaeological and historical resources
• Land development constraints
• Telecommunications interference
• Aviation considerations
• Visual, aesthetics impacts
• Identify and discuss other potential barriers
ANTHC will consider all potential environmental concerns associated with this project. ANTHC
has extensive experience using the comprehensive Indian Health Service (IHS) environmental
review procedures for conducting environmental analysis of all health and sanitation facilities
projects in all stages of development, as outlined in the IHS Environmental Review Manual
issued in January 2007.
4.4 Proposed New System Costs and Projected Revenues
(Total Estimated Costs and Projected Revenues)
The level of cost information provided will vary according to the phase of funding requested and
any previous work the applicant may have done on the project. Applicants must reference the
source of their cost data. For example: Applicants records or analysis, industry standards,
consultant or manufacturer's estimates.

Provide detailed project cost information based on your current knowledge and understanding of
the project. Cost information should include the following:
• Total anticipated project cost, and cost for this phase
Requested grant funding
■ Applicant matching funds — loans, capital contributions, in -kind
• Identification of other funding sources
• Projected capital cost of proposed renewable energy system
• Projected development cost of proposed renewable energy system
The total anticipated project cost is $688,400, including ANTHC's in -kind contribution. A detailed
construction cost estimate is contained in the attached 2012 Heat Recovery Feasibility Study.
The requested grant funding is $668,350. The remaining $20,050 is being donated by ANTHC in
the form of project and program management services.
4.4.2 Project Operating and Maintenance Costs
Include anticipated O&M costs for new facilities constructed and how these would be funded by
the applicant.
(Note: Operational costs are not eligible for grant funds however grantees are required to meet
ongoing reporting requirements for the purpose of reporting impacts of projects on the
communities they serve.)
As with all heat recovery systems, the operating cost will be minimal. The controls are automated
both at the power plant and at the water treatment plant/washeteria. The most expensive
components in the heat recovery system are the heat exchangers, and they normally have a
minimum of a 30-year life. Minor maintenance costs will occur periodically, but they will be
limited to valves, pumps, and possibly some replacement glycol. Approximately $500 per year
should be budgeted for maintenance.
4.4.3 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
A standard Heat Sales Agreement has been executed with AVEC, the supplier of the recovered
heat. The agreement states that the end users (combined utility building and washeteria) will pay
the equivalent of one third of the cost AVEC pays for fuel. This amount is much lower than the
retail price of fuel in the village. A standard BTU meter will be used to measure the amount of
recovered heat used at the water treatment plant.

Please address the following items, if know. (For Biomass Projects Only)
• What woody biomass technology will be installed (cord wood, pellets, chips, briquettes,
pucks).
• Efficiency of the biomass technology.
• Thermal or electric application.
• Boiler efficiency.
• Displaced fuel type and amount.
• Estimated tons of wood pellets or chips (specify) to be used per year, and average moisture

• Estimated cords of wood to be used per year, specify whether dry or green and the moisture
percentage.
• Ownership/Accessibility. Who owns the land and are their limitations and restrictions to
accessing the biomass resource?
• Inventory data. How much biomass is available on an annual basis and what types (species)
are there, if known?
SECTION 5— PROJECT BENEFIT
Explain the economic and public benefits of your project. Include direct cost savings, and
how the people of Alaska will benefit from the project.
The benefits information should include the following:
• Potential annual fuel displacement (gallons and dollars) over the lifetime of the evaluated
renewable energy project
• Anticipated annual revenue (based on i.e. a Proposed Power Purchase Agreement price
RCA tariff, or cost based rate)
• Potential additional annual incentives (i.e. tax credits)
• Potential additional annual revenue streams (i.e. green tag sales or other renewable
energy subsidies or programs that might be available)
• Discuss the non -economic
)ublic benefits to Alaskans over the lifetime of the
The potential fuel displacement is 14,200 gallons of the 23,000 gallons of fuel used at the
combined utility building and washeteria last year. The cost of the fuel is $4.50 per gallon
(summer 2012). The annual cost of fuel displaced for the combined utility building and
washeteria therefore equals $64,085. Over the 30-year life of the heat recovery system, the
savings will be $1,281,700 in today's dollars. Assuming a heat sales agreement specifying a
heat sales rate of 30% of displaced oil, the facilities will be saving $ 897,190 and AVEC will
receive new revenue of $ 384,510 over the 30 years.
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, a 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.
SECTION 6— SUSTAINABILITY
Discuss your plan for operating the completed project so that it will be sustainable.
Include at a minimum:
• Proposed business structure(s) and concepts that may be considered.
• How you propose to finance the maintenance and operations for the life of the project
• Identification of operational issues that could arise.
• A description of operational costs including on -going support for any back-up or existing
systems that may be require to continue operation
• Commitment to reporting the savings and benefits
This project increases the sustainability of the water treatment plant and washeteria by reducing
its operating cost by $1,281,700 over the 30-year life of the project. The minimal maintenance
and operating cost can be funded out of its revenue stream and out of its savings over the 30-
year life of the project.
Although the existing boilers will be maintained and are actually the primary heating source in the
water treatment plant and utility building, their use is to be greatly curtailed. The Native Village
of Kwinhagak is committed to meeting all reporting requirements over the entire length of the
reporting period.
SECTION 7 — READINESS & COMPLIANCE WITH OTHER GRANTS

Dear President Mark:
Re: Support Letter for the Quinhagak Recovered Heat Construction grant
The Alaska Rural Utility Collaborative (ARUC) has partnered with Quinhagak to provide
water/sewer system operation and maintenance for the community. ARUC fully supports
the Native Village of Kwinhagak's Alaska Energy Authority grant application for
construction of a recovered heat project to provide heat from the electrical power plant to
the sewer utility and washeteria buildings. We've seen similar recovered heat projects
lead to dramatically reduced heating costs in other ARUC water/sewer facilities. This
translates directly into to lower monthly water bills for local residents, schools, and
businesses. We see this as a way to make communities more self-sufficient, and of
reducing the burning of very expensive heating fuel. With the high cost of energy and
living in Kwinhagak, anything that can be done to reduce energy usage and utility costs
to local residents is critical.
Based on the proximity of the power plant to the sewer utility and washeteria buildings,
this project should reduce fuel usage dramatically.
In summary, we fully support this grant application.

Dear President Mark:
It is my pleasure to write this letter of support for your heat recovery project grant application to
the Alaska Renewable Energy Fund Round 6.
The Strategic Technical Assistance Response Team (START) initial site visit to Kwinhagak in
April 2012 helped to identify this potential energy saving project. It has been very rewarding to
see how the community has collaborated with the Alaska Village Electric Cooperative (AVEC)
and the Alaska Native Tribal Health Consortium (ANTHC) to better define this energy
efficiency opportunity and work to develop the grant application now being submitted.
Based on the preliminary feasibility study, an annual fuel savings of over 14,000 gallons of
diesel fuel can be expected from the heat recovery project. As well, considering the community's
bulk fuel storage challenges that currently result in spring -time air shipments of 55-gallon drums
of fuel, this potential savings will have even larger impact by avoiding significant amounts of
supplemental (and extremely high cost) fuel shipments before the summer barges can return.
From the START program's perspective, the Native Village of Kwinhagak has been extremely
responsive and pro -active in addressing their energy challenges and this is another example of
that initiative. We believe this project is worthy of Renewable Energy Fund support and will
result in substantial fuel savings and enhanced energy self-reliance. We look forward to
continuing our work together and assisting the community in meeting their energy goals.
Please contact me at your convenience if I can provide any additional information or assistance.
On behalf of the START program, we wish you the best of luck on this proposal.
Sincerely,

Dear President Mark;
It is indeed a pleasure to write this letter of support for your heat recovery project grant
application to the Alaska Renewable Energy Fund Round VI.
Heat Recovery is an excellent and proven method for reducing the amount of diesel needed to
provide heat to critical community infrastructure. The Strategic Technical Assistance Response
Team (START) identified this as a "low hanging fruit" item during our initial site visit to
Quinhagak.
We are very pleased that the community has come together with their electric company, Alaska
Village Electric Cooperative (AVEC), and with the Alaska Native Tribal Health Consortium
(ANTHC) to put this plan into a meaningful proposal.
We are confident that this project is worthy of Renewable energy Fund support and will result in
the substantial fuel savings predicted in the preliminary feasibility study.
Feel free to contact me for any questions or assistance you might need.

EXECUTIVE SUMMARY
The Quinhagak power house, washeteria and combined utility building were evaluated for
heat recovery potential. The total annual heating fuel used by both buildings is verified by the
community as approximately 20,000 gallons. An additional 3000 gallons of fuel consumption
is expected with expansion of the existing water and sewer system (currently under
construction). The estimated fuel savings realized by implementing a heat recovery system is
approximately 14,200 gallons. The estimated cost for the heat recovery project is $630,000.
The simple payback based on a fuel cost of $4.50/gallon is 9.8 years.
Assuming construction begins in summer of 2014, project cost with 2 years of 3% escalation
is $668,300.
1.0 INTRODUCTION
The Alaska Native Tribal Health Consortium (ANTHC) reviewed the feasibility of providing
recovered heat from the existing AVEC power plant to the existing combined utility building
and adjacent washeteria building in Quinhagak. ANTHC also developed a budgetary project
cost estimate based on Force Account Construction, including Engineering and Construction
Administration.
The existing combined utility building provides heat to the circulating water lines and heat to
one of the WSTs. The system was not designed for waste heat and will require controls and
installation of new heat transfer equipment, including a new heat exchanger and new
circulating pumps. This building is estimated to consume approximately 7,300 gallons of
diesel per year, with expansions currently under construction that will increase fuel
consumption to approximately 10,000 gal per year.
The existing washeteria building is hydronically heated. The city reports fuel consumption of
13,000 gallons/year and importantly, much of this load is present in the summer as well as
winter. New equipment will include a large brazed plate heat exchanger, a new circulator
pump, and controls to prevent back feeding of heat to the generator facility.
Some work will be required at the power plant, including adding marine jackets to the
engines, insulating existing piping, reworking of the AMOT temperature control valve and new
controls. This is included in the cost estimate. In addition, AVEC requires a heat sales
agreement which will result in approximately 30% of the fuel savings to be paid to AVEC.
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 information was obtained from AVEC regarding the 2011 power plant electrical
loads. End -user annual fuel use was obtained from a variety of sources, including the City,
Alaska Rural Utility Cooperative (ARUC), and engineering estimates. Where possible,
reported fuel consumption was used to validate engineering estimates. Site visits were made
to the existing WTP and washeteria to confirm accuracy of information obtained.
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
public buildings. 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 70% for a net heating value of 93,800 BTU per gallon.
The public buildings eligible for heat recovery are located within 1000-foot radius of the AVEC
power plant. This analysis evaluates the potential to provide recovered heat to the nearby
public buildings. The estimated average annual heating fuel consumption for the nearby
public buildings is 20,000 gallons at present with an additional 3000 gallons expected with the
expansion of the above ground water and sewer system (currently under construction).
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. The spreadsheet utilizes assumed time -of -day variations for
electric power production and heat demand. Power generation data from AVEC for fiscal year
2011 is used in the spreadsheet. The estimated heat rejection rate for the lead power plant
genset, a Detroit Diesel Series 60 DDEC4, is used to estimate available recovered heat.
Heating degree-days for Quinhagak were utilized for this site. All arctic piping is assumed to
be routed above grade. All exterior power plant hydronic piping is 3- or 4-in pipe. The
analysis includes 1-1/2" of insulation to be installed as part of this project.
The spreadsheet uses monthly heating degree-days to distribute annual fuel consumption by
month. The washeteria commercial heating loads are field verified as approximately 80% of
maximum utilization for 8 hours a day, 5 days a week. 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 each building:

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 above -grade arctic piping to the end users. 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 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.
4.1 AVEC PLANT TIE-IN
Marine Jackets will be added to the AVEC Generators to increase the available recovered
heat. If practical, an electric boiler will be added to pick up excess wind capacity when
available. All heat recovery piping will be insulated with a minimum of 1.5-in rubber foam
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. Additional controls will be added, including a
BTU meter and motorized bypass valve for coolant temperature control.
4.2 ARCTIC PIPING (Recovered Heat Loop)
The proposed arctic piping is based on ANTHC's standard arctic pipe design with a 3-in fiber
reinforced polypropylene carrier pipe (Aquatherm Climatherm SDR11), 4-in polyurethane
foam insulation, and aluminum outer jacket. The piping will be supported on sleepers on the
ground surface or helical piers where the ground isn't sufficiently stable. The heat recovery
piping will run from the power plant alongside the road to the abandoned sewer lagoon to the
end -user buildings.
Because multiple users are connected to the system, circulation pumps located at the
washeteria and combined utility building will circulate heating fluid to each user from the
AVEC facility. When users are not actively consuming recovered heat, their systems will
throttle down heating fluid flow to minimize power consumption.
The recovered heat fluid will be a 50/50 Propylene Glycol/Water solution to provide freeze
protection to the piping.
4.3 END -USER BUILDING TIE-INS
End -user building tie-ins typically consist of brazed plate heat exchangers with motorized
bypass valves or heat injection pumps to prevent back feeding heat to AVEC or other users.
Plate heat exchangers located in the end -user mechanical rooms will be tied into the boiler
return piping to preheat the boiler water prior to entering the boiler. Where required, a heat
injection pump will be used instead of a motorized bypass valve to avoid introducing
excessive pressure drop in the building heating system. The maximum anticipated delivered
recovered heat supply temperature is about 190F. 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.
Each facility will also receive a BTU meter to provide recovered heat use totalization and
instantaneous use.
4.4 PRIORITIZATION OF RECOVERED HEAT
Recovered heat prioritization is accomplished by setting the minimum recovered heat
temperature for each user, with successive load shedding as the recovered heat loop
temperature falls. The user with the highest allowable recovered heat temperature will be
removed from the system first. The user with the lowest allowable recovered heat
temperature will be removed from the system last.
The system will also provide freeze protection in the event a user's boiler system temperature
falls below a minimum temperature, typically 50-100 degrees F.
4.5 RIGHTS -OF -WAY ISSUES
There are no apparent conflicts with rights -of -ways for the arctic piping between the power
plant and the end -user buildings, 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.
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). 450 MBH capacity
Primary: 50 GPM 195F EWT (50% ethylene glycol), 1.5 PSI max WPD
Secondary: 50 GPM 19OF LWT (50% propylene glycol) 1.5 PSI max WPD
HX-2: (Combined Utility Building). 250 MBH capacity.
Primary: 25 GPM 180F EWT (50% propylene glycol), 1.0 PSI max WPD
Secondary: 25 GPM 175F LWT (50% propylene glycol) 1.5 PSI max WPD

Secondary: 25 GPM 175F LWT (50% propylene glycol) 1.5 PSI max WPD
5.2 Arctic Piping
The length of heat recovery loop piping between the power plant and most distant facility is
approximately 1600ft, round trip. The arctic piping utilizes 3-in carrier pipe to minimize
pressure drop and reduce pumping energy. The pipe itself consists of a 3-in fiber reinforced
polypropylene carrier pipe, 4" of polyurethane insulation and an aluminum outer jacket. The
specified product is durable enough for direct exposure to the weather and resistant to
crushing.
5.3 Circulating Pumps
P-HR1: Heat recovery loop pump at combined utility building
Flow = 25 GPM, Head = 35 ft
Initial Selection: Grundfos Magna with integrated VFD.
P-HR2: Heat injection pump in combined utility building.
Flow = 25 GPM, Head = 15 ft
Initial Selection: Grundfos 50-60F.
P-HR3: Heat recovery loop pump at washeteria building
Flow = 25 GPM, Head = 35 ft
Initial Selection: Grundfos Magna with integrated VFD.
P-HR4: Heat injection loop in Washeteria
Flow = 25 GPM, Head = 14 ft
Initial Selection: Grundfos, 50-60F
5.4 Expansion Tank

5.6 CONTROLS
Heat recovery system in each building will use an off the shelf differential temperature
controller to start/stop a heat injection pump. Control will provide load shedding, freeze
protection, and prevent backfeeding of boiler heat into heat recovery system. In addition, A
BTU meter will be provided at each facility, displaying instantaneous temperatures and heat
transfer, as well as totalizing BTUs used.
Differential Controllers: 2 required Tekmar Model 155 differential temperature control
BTU Meters:
BTU-1 Combined Utility Building: KEP BTU meter with 2" magnetic flow meter and matching
temperature elements.
BTU-2 Washeteria: KEP BTU meter with 2" magnetic flow meter and matching temperature
elements.
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. Incremental costs for arctic pipe, end -user building renovations, and
overhead and freight are estimated individually for each of the other end -user buildings (refer
to attached cost estimate).
The estimated project cost for is $630,000. Estimated fuel savings are about 14,200 gallons.
Using a 2011 fuel price of $4.50/gallon results in estimated community savings of $64,000 for
a simple payback of 9.8 years.
Funding for design and construction isn't expected before fall 2013, with construction
occurring summer of 2014. With 2 years of escalation at 3% per year, the estimated project
cost in 2014 is $668,300.

Washeteria Commercial Loads
Washeteria Loads reflect operation for 8 hours a day, 5 days a week, with average load at
80% of design. It's worth noting that loads will approach 100% of design if users
from St. Michael come to Stebbins for cheaper laundry use.
