2.4 PROJECT DESCRIPTION
Provide a brief one paragraph description of your proposed project.
This project will provide a heat recovery system to support the heating requirements of five City -
operated and owned buildings in Togiak. The objective of this project is to reduce the
consumption of expensive heating fuel by utilizing available recovered heat.
There are several community buildings within a 500 foot radius of the Alaska Village Electric
Cooperative (AVEC) power plant, offering an excellent opportunity to capture a maximum
amount of waste heat from the plant for hydronic heating.
A detailed Heat Recovery Analysis was completed for the City of Togiak and Alaska Native
Tribal Health Consortium (ANTHC) in June 2010 by Alaska Energy and Engineering, Inc.
(Report Attached). The findings and preferred alternatives developed by this analysis will be
used as the basis for the project proposed in this application.
The proposed project will design and construct a heat recovery system between the AVEC power
plant and the following end -user community buildings: 1) Water treatment Plant, 2) Clinic, 3)
Police Station, 4) City Office, and 5) "Old School" Community Activity Building. The new
system will capture jacket water heat generated by the AVEC plant that is currently wasted to the
AEA12-001 Grant Application Page 2 7/1H2011

Renewable Energy Fund
Grant Application Round 5
atmosphere by power plant radiators. The recovered heat will be transferred by insulated glycol
piping to the end -users. The new system will tie into the end -users' heating systems using heat
exchangers, control mechanisms and any required upgrades to the existing building hydronic
systems.
2.5 PROJECT BENEFIT
Briefly discuss the financial and public benefits that will result from this project, (such as reduced fuel
costs, lower energy costs, etc.)
From the 2010 Heat Recovery Analysis, the total estimated fuel savings realized by
implementing the proposed heat recovery system is 13,700 gallons per year. With a 2011 local
heating oil price of $6.18 per gallon, the estimated savings in terms of heating costs to end -users
is $84,666 per year. The following is a summary of annual fuel use and estimated and estimated
heat utilization in equivalent gallons of fuel for each building:
Facility Estimated Annual Estimated Heat A'
Fuel Use Gallons Delivered Gallt�ns
-Water Plant 2500 2050
Clinic 2000 1650
Police Station 1200 1000
City Office 1000 800
Old School 10000 8200
Total 16700 13700
Does not account for peak DHW loads
This project will significantly lower the operating cost of the five City -operated facilities listed
above, and save many thousands of gallons of fuel oil during its design life. In addition, the
expectation of escalating fuel oil costs will almost certainly increase savings over time.
Reducing O&M costs directly benefits the sustainability of these facility and the important
public services they provide to Togiak residents.
2.6 PROJECT BUDGET OVERVIEW
Briefly discuss the amount of funds needed, the anticipated sources of funds, and the nature and source
of other contributions to the project.
Design and construction of the proposed heat recovery project is estimated at $486,180, which
includes $36,000 for design services and $450,180 for construction activities.
The total amount of funding requested from AEA to support this project is $443,030.
To support this project $43,150 will be provided as in -kind contributions from the City of Togiak
and the Alaska Native Tribal Health Consortium. The City of Togiak has pledged to provide
$25,000 as an in -kind equipment rental contribution, as well as $6,000 in local administration
and management services during the course of the project. ANTHC will provide contract
administration and project management services for the project at an estimated value of 2.5% of
the overall project cost, or $12,150.

The Alaska Native Tribal Health Consortium (ANTHC) supports Togiak's efforts to implement a
renewable energy project to improve community sustainability. ANTHC's Division of
Environmental Health and Engineering (DEHE) has extensive resources to directly support this
grant application and implement AEA -awarded grant projects. ANTHC/DEHE offers a complete
range of in-house engineering and project management services for project planning, contract
administration, project commissioning, and technical support.
Design for this project will be completed by the Regional Corporation's professional
engineering services firm, Bristol Engineering Services Corporation. Mechanical and electrical
components of design will be completed by appropriately qualified subcontractors. Bristol has
an established term contract for engineering services with both ANTHC and the City of Togiak,
which meets compliance with applicable federal and state procurement regulations and allows
for a streamlined contract award process. In addition, Togiak has worked extensively with
Bristol to complete design of multiple sanitation facility projects over the past several years. The
most recent design effort for Togiak—Water Treatment Plant Renovations —was recently
completed by Bristol and is planned for construction in 2012. Bristol has coordinated closely
with Togiak concerning their plan to complete a heat recovery system, and has included
provisions for heat recovery components in the new Water Treatment Plant design.
Construction for this project will be completed via procurement of contracted construction
management (CM) services. Summit Consulting Services, Inc. is established as a term
contractor with ANTHC and the City of Togiak and is available to provide CM services for the
proposed heat recovery project. Summit has a well established relationship with Togiak as they
have completed construction projects for Togiak in the past and are currently under contract to
complete construction of the Water Treatment Plant renovation project in 2012. For the
proposed heat recovery project, Summit will provide a qualified superintendent, specialty trades

personnel (i.e., electricians, plumbers, and mechanics) and will hire local labors to complete
construction.
ANTHC supports projects after construction through dedicated Federally funded programs to
provide technical assistance and support for operations of constructed facilities such as water
plants, clinics, community -wide water and sewer systems, etc. ANTHC support personnel
skillfully troubleshoot issues and assist local operators and owners to ensure long-term system
sustainability.
3.5 Project Communications
Discuss how you plan to monitor the project and keep the Authority informed of the status.
Darryl Thompson, City Administrator for Togiak, will act as the primary point of contact for the
City of Togiak and will oversee design and construction contracts jointly with ANTHC.
Eric Hanssen, P.E. will be the point of contact from ANTHC for establishing and managing
design and construction contacts.
Requests for reimbursement will include detailed financial reports, project narrative updates, and
when appropriate photos of construction progress. Reimbursement requests and project
narratives updates will be provided on a monthly basis with allowance for construction shut
down during breaks in the construction season.
3.6 Project Risk
Discuss potential problems and how you would address them.
Recovered heat projects are low risk, the technology and implementation are well proven in rural
Alaska.
Excavation work involved in installation of buried heat recovery pipe has associated risk based
on unknown soil conditions. Potential problematic subsurface conditions could include
archaeological findings, contaminated soils or permafrost conditions. There is some risk
associated with this design/construction effort until additional information on soil conditions is
known.
There is some risk the actual cost of the project may exceed the current estimate depending on
the results of the field work and design effort. If this should this occur, the design can be value -
engineered to ensure construction of a beneficial project that remains within budget.

Dear Mayor Forbes:
Re: Alaska Energy Authority (AEA), Renewable Energy Grant Prograin
The Traditional Village of Togiak is pleased to support the City of Togiak in this proposal for the
AEA, Renewable Energy Grant Program for a heat recovery system. Currently, our
community's water treatment and distribution system requires a significant amount of fuel each
year for operation. The proposed renewable energy grant that you are applying for will pave the
way for design and construction of a heat recovery system that will bring significant benefits to
our community. Given the extremely high cost of fuel in rural Alaska, this project is one of
Togiak's top priorities. A future heat recovery system will dramatically reduce energy costs
related to our community's water system based on the reduced dependence on fuel oil for
heating. In addition, the anticipated operational savings will allow for lower utility fees and a
reduced cost of living for Togiak's residents.
For these reasons, we fully support the City's efforts in pursuing this funding opportunity.

ANTHC-Togiak Heat Recovery Analysis June 20, 2010
Alaska Energy and Engineering
EXECUTIVE SUMMARY
Five community facilities in Togiak were evaluated for heat recovery potential. Total
estimated annual heating fuel use of these facilities is approximately 16,700-gallons.
Estimated fuel savings realized by implementing a heat recovery system is 13,700-
gallons. The estimated cost for the heat recovery project is $486,180. The simple
payback based on a fuel cost of $5.00/gallon is 7.1-years.
Alaska Energy and Engineering, Inc. was retained by the Alaska Native Tribal Health
Consortium (ANTHC) to review the feasibility of providing available recovered heat
from the existing AVEC power plant to the existing water plant and adjacent
community buildings in Togiak, and provide a budgetary project cost estimate based
on Force Account Construction, including Design Engineering and Construction
Administration.
There is an existing heat recovery system in Togiak that used to provide recovered
heat to the old Togiak school (old school). The heat recovery system has been out of
service for several years, since a new school was constructed at a remote location and
the existing school facilities were abandoned and partially demolished. The City has
taken over the remaining school facilities and is in the process of renovating them for
community use. For purposes of this report, it has been assumed that the existing
heat recovery equipment at the power plant will be modified including refurbishing or
replacing the existing heat exchanger and installing new circulating pumps.
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 existing power plant cooling system and heat
exchanger. 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 was obtained from the Alaska Village Electric
Cooperative (AVEC) regarding the existing generation equipment and power plant
heat loads. End -user annual fuel use was obtained from a variety of sources,
including the City and engineering estimates. No site visits were made to confirm
accuracy of information obtained.
f+ [�Gly/ 4AN 1
The purpose of this study is to provide an estimate of the heat that can be recovered
from the jacket water of 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 75% for a net
heating value of 100,000 BTU per gallon.
There are several community buildings within a 500-foot radius of the AVEC power
plant. This analysis evaluates the potential to provide recovered heat to the Clinic,
Police Station, City Office, Water Treatment Plant (WTP) and old school. The
estimated average annual heating fuel consumption for the five end -user's is as
follows: Clinic is 2000-gallons, Police Station is 1200-gallons, City Office is 1000-
gallons, Water Treatment Plant (WTP) is 2500-gallons, and the old school is 10000-
gallons. The combined estimated annual fuel use of the five facilities is 16,700-gallons.
ANTHC-Togiak Heat Recovery Analysis June 20, 2010
Alaska Energy and Engineering
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 utilizes assumed time -of -day
variations for electric power production and heat demand. Power Cost Equalization
data for fiscal year 2008 was used in the spreadsheet. The estimated heat rejection
rate for the lead power plant genset, a Cummins QSX15 G9, is used to estimate
available recovered heat. Heating degree-days for Dillingham were utilized for this
site. All arctic piping is assumed to be routed below grade. All exterior power plant
hydronic piping is assumed to be 3" pipe with 1" of fiberglass insulation and installed
above grade. Information provided by AVEC was used to estimate the heating load for
the power plant, which includes two insulated 20-foot Connex storage units.
The spreadsheet uses monthly heating degree-days to distribute annual fuel
consumption by month. The monthly heat load is then allocated by hour of day using
an estimated daily temperature variation (diurnal cycle). 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 currently rejected to the atmosphere by the radiators. The recovered heat
will be 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. The recovered heat fluid is pumped through arctic pipe to the end -user
facilities, and is typically tied into the end -user heating system using either a plate heat
exchanger or cabinet unit heater.

ANTHC-Togiak Heat Recovery Analysis June 20, 2010
Alaska Energy and Engineering
AVEC PLANT TIE-IN:
No modifications to the AVEC power plant cooling system are included, except those
required to replace the existing power plant heat exchanger, provide new circulating
pumps, and install new instrumentation.
All piping will be insulated with a minimum of 1" 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.
ARCTIC PIPING (Recovered Heat Loop
The proposed arctic piping is a pre -insulated buried piping system. The piping will be
routed from the AVEC plant within existing rights -of -way to the end -user buildings.
The arctic piping system is a pre -insulated, bonded PEX piping system. The pipes
consist of Cross -Linked Polyethylene carrier pipe and LDPE outer jacket bonded to
polyurethane foam insulation. The carrier piping uses hydraulically pressed bronze or
steel couplings, similar to those used in high-pressure hydraulic hoses. The system
comes complete with all fittings, tools and accessories required for assembly. 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 either brazed plate heat exchangers or
cabinet unit heaters. Plate heat exchangers located in the end -user mechanical rooms
will be tied into the boiler return piping to pre -heat the boiler water prior to entering the
boiler. Where Toyo-style heaters are used, cabinet unit heaters will be located in the
occupied space. 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.
Typical 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" 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.

RIGHTS -OF -WAY ISSUES:
There does not appear to be any 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 City
to define the parties' responsibilities, the cost of recovered heat, and to authorize the
renovation of 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.

5.2 Arctic Piping
The length of heat recovery loop piping between the power plant and old school
(furthest building) is approximately 1200'-feet, round trip. The arctic pipe is sized to
minimize pressure drop and reduce pumping energy. Each branch of the arctic pipe is
sized for the specific flowrate for that branch. The arctic piping sizes include 90mm,
75mm, 1.25" and 1" PEX piping.

5.3 Circulating Pumps
P-HR1: Heat recovery loop to end -user buildings
Flow = 77 GPM, Head = 34'
Initial Selection: Grundfos UPS 50-160F, 77 GPM at 34' TDH, 1-1/2 HP
5.4 Expansion Tank
Total heat recovery loop volume is approximately 400-gallons. Pressure relief at the
power plant heat exchanger will be 50 PSIG and the maximum normal operating
pressure will be 90% of maximum (45 PSIG).
ET-1: System requirements: 46 gallon tank and 28.2 gallon acceptance
Select: Extrol AX-120V, 66 gallon tank and 34 gallon acceptance
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
water treatment plant, and 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 all five end -users is $486,180. Estimated fuel savings
are about 13,700-gallons. Using an assumed fuel price of $5.00/gallon results in
estimated savings of $67,500 for a simple payback of 7.1-years.
