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 significantly exceeds that required by the water treatment
plant and store for the entire year, as indicated by the attached 2012 Heat Recovery Feasibility
Study.
The only realistic alternative to utilizing the recovered heat is to continue to burn over 7,700
gallons of fuel oil to provide the heat required by the water treatment plant and store. The cost of
fuel is almost five times the cost of the recovered heat. The feasibility study and some
preliminary design are contained in 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,
heating degree days, passive losses for power plant heat and piping, and arctic piping losses.
The spreadsheet uses assumed time -of -day variations for electric power production and heat
demand. Power generation data from fiscal year 2011 is used in the spreadsheet. The estimated
heat rejection rate for the lead power plant genset, a Detroit Diesel 60, is used to estimate
available recovered heat. Heating degree-days for Pilot Station (a nearby location) were used for
this site. All arctic piping is routed below grade except for the existing well lines. All interior power
plant hydronic piping is assumed to be 4-in pipe with 1 in of foam rubber insulation.
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 existing store and WTP building are hydronically heated. An energy audit of the WTP
performed in 2011 verified approximately 6,200 gallons/year of fuel consumption. The fuel
consumption for the existing city store was estimated at approximately 1,500 gallons. All the fuel
currently consumed is expected to be offset with recovered heat from the power plant.
The existing power plant was modified in 2007 for heat recovery and has a brazed plate heat
exchanger already installed. Per conversations with AVEC, the existing heat recovery controls
AEA13-006 Grant Application Page 7 of 20 713H2012

Grant Application i � ENERGY AUTHORTY�
and piping need to be upgraded to prevent excessive pressure drop through the cooling system
and the cooling system needs to be insulated. No other work is required to incorporate heat
recovery.
The WTP was modified in 2007 for heat recovery and has a brazed plate heat exchanger and
circulation pumps already installed. The piping in the WTP needs to be reconfigured to provide
maximum recovered heat benefit, the heat recovery controls replaced, and a BTU meter added
for billing. No other work is required to incorporate heat recovery.
The community store was promised access to the heat recovery system in trade for running the
heat recovery lines across the store property. New work includes adding a hydronic unit heater
and a BTU meter for billing. No other work is required to incorporate heat recovery.
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
All 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 7,700 gallons per year. While this reduction will not
change the price of oil in Marshall, it will significantly reduce the community's consumption of oil,
replacing that consumption with recovered heat from the diesel engines.
4.3 Proposed System
Include information necessary to describe the system you are intending to develop and
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
address
The heat recovery system captures jacket water heat generated by diesel engines that is
typically rejected to the atmosphere by the radiators. The recovered heat is transferred via
below -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
are used to prevent subcooling of the generator engines and associated reduction of 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 or, in the case of the store, a h dronic unit heater.

The power plant cooling system currently sends the entire generator cooling flow through the
heat recovery heat exchanger. As long as only one engine is running, this is not a problem, but it
becomes a problem when more than one engine runs. To address this, a bypass line around the
heat exchanger will be installed with a modulating control valve to prevent excessive back
pressure against the generator engines. An existing three-way valve on the cold side of the heat
exchanger prevents subcooling of the power plant system.
All heat recovery piping inside the power plant will be insulated with a minimum of 1-in foam
insulation. 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.
ARCTIC PIPING (Recovered Heat Loop)
The existing heat recovery piping between the power plant and the water treatment plant will
remain and be reused. The recovered heat fluid will be replaced with 50/50 propylene
glycol/water solution to provide freeze protection to the piping.
WATER TREATMENT PLANT BUILDING TIE-IN
The water treatment plant building tie-in consists of two existing heat recovery circulator pumps,
an existing brazed plate heat exchanger, and an existing motorized bypass valve to prevent back
feeding heat to power plant. Currently the three-way valve controls don't work and the heat
exchanger is piped to serve only the circulating water mains and water storage tank.
The proposed design will modify the piping so that the heat recovery system serves the entire
water treatment plant building load, and the three-way valve will be replaced with a heat injection
pump. The controls will be replaced to provide a working system.
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.
The water treatment plant will also receive a BTU meter to provide recovered heat use
totalization and instantaneous use.
COMMUNITY STORE BUILDING TIE-IN
The community store will have a hydronic unit heater and BTU meter installed for recovered heat
use and the existing heat recovery lines will be extended to the new equipment.
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.

• 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.
4.4.1 Project Development Cost
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

Renewable Energy Fund Round 6 GEM
Grant ApplicationENERGYAUTHORITY
• Projected capital cost of proposed renewable energy system
• Projected development cost of proposed renewable energy system
The total anticipated project cost is $189,200, including ANTHC's in -kind contribution. This is
based on the detailed cost estimate contained in the attached 2012 Heat Recovery Feasibility
Study. The requested grant funding is $183,200. The remaining $6,000 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. 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 will be executed between the power company and the City of
Marshall. The agreement will define the terms and methods for heat sales. Typical heat sales
agreements charge end users the equivalent of one third of the cost of the fuel displaced. 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.
4.4.4 Project Cost Worksheet
Complete the cost worksheet form which provides summary information that will be considered
in evaluating the project.

SECTION r 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: j
• 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 public benefits to Alaskans over the lifetime of the project
The potential fuel displacement is 7,700 gallons of fuel used at the water treatment plant and
the village store. The cost of the fuel is $4.01 per gallon. The annual cost of fuel displaced for
the water treatment plant and village store therefore equals $31,035 in 2012 dollars. Over the
30-year life of the heat recovery system, the savings will be $620,700 in today's dollars.
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
AEA13-006 Grant Application Page 14 of 20 7/3//2012
Renewable Energy Fund Round 6
Grant Application 4EW7 -� ENERGY AUTHORITY
• 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 village store by reducing
their combined operating cost by $620,700 over the 30-year life of the project. The minimal
maintenance and operating cost can be funded out of their revenue stream and their 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, their use is to be greatly curtailed. The City of Marshall is committed to
meeting all reporting requirements over the entire length of the reporting period.
SECTION 7 — READINESS & COMPLIANCE WITH OTHER GRANTS

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
HX-3: (Washeteria). 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
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
Total heat recovery loop volume is approximately 900 gallons. Pressure relief at the power
plant heat exchanger will be 45 PSIG and the maximum normal operating pressure will be 40
PSIG.
ET-1: System requirements: 140 gallon tank and 80 gallon acceptance
5.5 GLYCOL MAKEUP
A glycol make-up system at the combined utility building will be provided to accommodate
filling the system and adding additional glycol.
GT-1: Select AXIOM SF100 55 Gal Glycol make-up 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.
