SECTION 2 – PROJECT SUMMARY
Provide a brief 1-2 page overview of your project.
2.1 PROJECT TYPE
Describe the type of project you are proposing, (Reconnaissance; Resource Assessment/
Feasibility Analysis/Conceptual Design; Final Design and Permitting; and/or Construction) as
well as the kind of renewable energy you intend to use. Refer to Section 1.5 of RFA.
The Southeast Island School District (SISD) request is for Phase II–Resource
Assessment/Feasibility Analysis/Conceptual Design, Phase III−Final Design and Permitting,
Phase IV−Construction funding of a cordwood-fired hydronic heating system to supplement the
oil-fired heating system in the Howard Valentine School in Coffman Cove, Alaska.
2.2 PROJECT DESCRIPTION
Provide a one paragraph description of your project. At a minimum include the project location,
communities to be served, and who will be involved in the grant project.
The wood fired supplemental heating system would be located at the Howard Valentine School
Site in the City of Coffman Cove on Prince of Wales Island in Southeast Alaska. The project
would also serve the residents of the City of Coffman Cove. The entities involved in this project
would be Southeast Island School District, a design engineering firm, local contractors, and the
Alaska Energy Authority. We would rely on Alaska Energy Authority for guidance with the
project.
The use of wood biomass (cordwood) to heat the school will replace 85% of the fuel oil
consumption. The project involves placing one thermal storage type wood-fired hydronic
heating unit adjacent to the school site and running underground insulated pipes from the wood-
fired heater to interface with the school’s heating system. Heat energy from biomass will
significantly decrease heating costs for the school. Wood is available from waste from local saw
mills, USFS small sales, from wood left behind in landings, and from small local firewood
cutters.
2.3 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. Include a project cost summary that includes an estimated total cost
through construction.
The total project cost is $355,056. The source of funds will be the state Renewable Energy grant
of $341,056, with an SISD in-kind contribution of $14,000 in labor. Project costs include:
Engineering: $35,700 – Resource assessment – Feasibility Analysis – Design - Permitting
Building Construction: $212,600.
Heat Transfer System: $15,000 – Connecting piping – Heat System Interface
Project Management by AEA term contractor: $35,700.
In-Kind Labor by two school district maintenance personnel: $14,000 (4 wk@60 hr/wk)
20% contingency: $59,176.
2.4 PROJECT BENEFIT
Briefly discuss the financial benefits that will result from this project, including an estimate of economic
benefits(such as reduced fuel costs) and a description of other benefits to the Alaskan public.
SISD will save $23,865 in heating costs the first year by replacing costly fuel oil with locally
available cordwood. Money that has previously left the community in the form of payments to
the heating fuel provider will be invested locally. The contract for providing wood could be
split among a several families, providing supplemental income. The contract for the supplying
wood could be the impetus to start a small business that would hire local people. The money
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 4 of 14 9/3/2008
earned can be used to purchase housing, groceries, fuel, food and other economic goods and
services. The $23,865 saved by SISD would go back to the general fund and would be used to
purchase a number of items: part of a teacher’s salary, aide time for the school site or
educational materials for the schools. Families would remain in the town when jobs are created,
and the schools remain open. Schools are the center of community wellness in many ways. With
low-cost heat we can open the school gym to nightly activities. Open gym gives students and
adults some place to go and something to do. Communities become healthier, where community
members can use fitness equipment, play volleyball, and help students with archery, and
basketball tournaments and hold community events in the gym. Without these options people
find ways to entertain themselves not always positive - getting into trouble and that is costly for
society, both locally and for the state when they end up incarcerated.

Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 7 of 14 9/3/2008
The United States Forest Service (USFS) recently published a map and reconnaissance report ( See
Appendix A attached) The potential wood resources available for the school district is 5000 cords. That is
the equivalent of well over 61 years supply. There are also other private sources of wood available, along
with waste wood from the local saw mills. Pros: the school is located in the heart of the Tongass National
Forest, the largest forest in the nation. Wood sources are located close to the City of Coffman Cove.
Transportation of wood to school district is reasonable since wood sources are located nearby. Wood can
be obtained and stored for up to a year or more ahead of time, ensuring a reliable and reasonable source of
energy. It is a renewable source of energy. Wood is an organic, non contaminating, biodegradable
renewable material. Cons: Cordwood takes up more room than fuel oil, and needs a larger dry storage
area. It also requires more manual labor than turning a switch; it also generates ash which needs to be
disposed of.
Item Pros Cons
Continues Using Fuel Oil –
don’t supplement with wood
fired boilers.
Requires no changes to existing
heating system at the school and
doesn’t create any new
industries in Southeast Alaska,
Prince of Wales or local towns.
High fuel prices, money leaves
community, no local job created,
fluctuating fuel oil prices create
no stability for estimating
budgets, no economic
development – families leave
communities, schools close.
Wood source Locally available - Saw mills,
slash piles, thinning projects,
wood sources located on Prince
of Wales, in and near Coffman
Cove. Renewable nontoxic,
energy source,
After years and years of use,
easy access to the wood sources
could necessitate farther travel
and increase the cost.
New wood products developed A wood pellet industry could be
developed on Prince of Wales
Island and offer a cheaper
supplemental product for
purchase to be used in Biomass
fired Boilers. A new business
could be created in Coffman
Cove delivering the product to
homes and the school. Allows
for partnership development
among entities in Southeast
Alaska and groups on Prince of
Wales Island
Transportation costs to get
pellets to the school site might
increase the fuel costs and
reduce savings to school district.
Priorities for product use may
not favor rural and remote
towns.
Amount available 5000 cords available
Renewable resources with
potential to use species not
considered such as Alder
Some distant areas of harvest
could be more than 50 miles
from Coffman Cove. Might
require and investment into new
equipment to harvest new
sources of wood biomass
( thinning for example)
No information on amount of

AEA 09-004 Grant Application Page 8 of 14 9/3/2008
Wood contracts Local people willing to bid
contracts, creating jobs, and
keeping families in small
communities and children in
community to keep small
schools open. With local people
supplying wood easy to contact
them and follow up on contracts
Competitive bid process might
be awarded to an outside bidder
who will raise the price of wood
and decrease SISD savings.
Requires deadline dates in the
wood supplier’s contract and
follow up by maintenance
personnel to assure supply.
Wood condition Lots of dead standing wood, and
thinning slash, located close to
Coffman Cove. Only requires
short drying time for use of
product.
Has to be stored out of the
weather ahead of time in order to
reduce moisture content. Green
wood will need to be stored for a
longer period than dry wood,
taking up more space
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.
The current system used to heat Coffman Cove School contains three oil-fired boilers. Each boiler
produces 266,000 BTU’s per hour, for a total 798,000 btu/hr for the group of three. The boilers are less
than one year old, and have an overall efficiency rating of 75% to 80%.
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.
Adding a supplemental wood-fired hydronic heating system will have little impact on the existing biomass
energy resource. Thorne Bay District Ranger, Jason Anderson, provided an attachment (Attachment No. 3)
that shows areas with plenty of renewable biomass energy source. Removal of the trees allows more light
to hit the forest floor and other trees will grow to replace the removed trees. In the case of slab wood from
sawmills, wood-fired hydronic heaters can use wood that has in the past been stacked and left to rot. When
the USFS offers small thinning sales, a contract to remove the thinned wood could remove wood that only
ends up rotting on the forest floor and generates green house gasses. At this time very little of the thinned
woods are used. The positive impacts: cutting wood for the school district will create a job that allows
money to stay in the community and keep a family with children employed and living in Coffman Cove.
When families stay in small towns, the schools remain open, SISD hires local people to work at the school,
adding to the economic benefit of the community.
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
The existing energy resource is fuel oil that is used to heat the school. The current price is $4.46 per gallon
for No. 2 fuel oil. The school will use approximately 10,000 gallons of fuel oil per year or $ 44,600.
Switching from fuel oil to wood heat for 85% of the heating needs will have little or no impact on the
people of Coffman Cove, since fuel oil for the school is purchased from an out-of-town distributor, and the
money leaves the community.

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
Description of renewable energy technology specific to project location:
The proposed wood-fired hydronic heating system will provide building heat and domestic hot
water to the Coffman Cove School. The heat source will consist of cordwood fired hydronic
heater located in a pre-engineered insulated building (see Figures 1 and 2 of Wood Heat Building
in Attachment No. 4). An adjacent fabric-covered structure will provide 2,200 sq ft of covered
storage for one heating season of wood. Heat will be transferred from the heat building to the
school mechanical room in a 50-ft long buried hydronic loop using flexible insulated Pex piping
system such as Ecoflex. The building hydronic loop will be separated from the district heating
loop with a heat exchanger to separate the non-pressurized wood-fired system from the building
pressurized hydronic system.
Because this is a cordwood fired system, it will use more operating labor than a system using bulk
biofuel such as wood pellets or chips. To minimize the labor, cordwood would be packaged on
half-cord skids or pallets and moved into the stoking area with a small skid steer loader such as a
Bobcat. A cordwood fired hydronic heater would be selected with primary/ secondary
combustion chambers and a large heat storage tank to maximize efficiency and minimize exhaust
emissions.
Optimum installed capacity and capacity factor:
The system will be designed to displace 85% of the oil previously used in the facilities. This is
done to reduce the cost of the project from overcapacity and to optimize system operation. The
wood-fired hydronic unit is sized to handle 60% of peak load with 6-hr of heat storage between
firings.
Anticipated annual generation:
The wood-fired hydronic system will produce an annual net output of 877,200,000 btu to the
school, through batch firing of cordwood, coupled with thermal storage in the 3200 gallon hold-
up volume of the heating unit. Annual wood use anticipated is 81 cords of wood to 30%
moisture, wet basis.
Anticipated Barriers:
No potential barriers at this time. There is plenty of biomass available, and wintertime access is
rarely hampered by snow.
Basic Integration Concept:
The heating systems will be connected to each other by a heat exchanger on the return side of the
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 10 of 14 9/3/2008
school hydronic system to separate the heat transfer fluids and system pressures.
Delivery Method:
The cordwood-fired heating system will deliver heat to the school mechanical system through a
buried insulated hot water loop and a circulation pump.
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.
The land for the project is owned by SISD. There are no potential land ownership issues. The
School District supports the project. There are no access issues as the school district controls
access to the site. See attached support letter in the form of a School Board Resolution
(Attachment No. 5). Also see attached City of Coffman Cove resolution supporting the wood
fired boilers.
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
List of Permits: The only permit that is required would be the State Fire Marshal’s approval for a
wood fired hydronic heating unit at the School location. Southeast Island School District has site
control. Because of the small size of the heating unit, a DEC air quality permit will not be
required.
Timeline: Once the project has been funded and the mechanical drawings drafted we would
proceed with the application for the Fire Marshall’s approval. The time line for Fire Marshal’s
approval and permit is approximately 4 weeks.
Barriers: A delay in the Fire Marshall granting approval of the project would cause a delay in
the installation of the 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
Threatened or Endangered Species: The school site has already been disturbed and filled with shot
rock, and contains no threatened or endangered species at the locations.
Habitat Issues: The school site has already been disturbed and filled with shot rock, and there are no
habitat issues that would need to be addressed.
Wetlands and other protected areas: The school is not located in a wetland or other protected area, as
the area was filled with shot rock prior to school construction.
Archaeological or Historical resources: The project area is not located where archaeological, cultural, or
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 11 of 14 9/3/2008
historical resources are located.
Land Development Constraints: There are no land constraint issues at the Coffman School site. The
School District owns the land surrounding the possible location of the wood fired heater building and there
is plenty of land surrounding the areas.
Telecommunications interference: There are no satellite dishes, phone lines, cell towers or cables in the
areas selected for the wood fired boilers to interfere with telecommunications.
Aviation considerations: The schools are located away from the seashore. All our aviation is conducted
by float planes and the wood fired boilers would be located in an area that would not interfere with float
plane operations.
Visual and Aesthetics Impacts: The location selected for the wood fired boilers will have a minimal
affect on the surrounding areas as the wood-fired hydronic heating units must be contained inside a
building and fenced to keep people away from the area.
Identify and discuss other potential barriers: Other barriers could include placing the project in an
earthquake or tsunami potentials zone. Neither of these events would affect the students at the schools.
The schools are located on one of the highest locations in town, away from tsunami danger, and the wood
fired hydronic heater is self-contained in its own building away from the main school. Heat piping is
underground and plumbed directly to the school boiler room, where students do not have access, so broken
pipes are not an issue in the event of an earthquake. The proper wood-fired hydronic heaters have a high
efficiency and low emissions, and meet or exceed current and anticipated EPA clean air requirements.
4.4 Proposed New System Costs (Total Estimated Costs and proposed 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,

Electricity for circulation pump, building lighting, and combustion fan: $505/yr
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 12 of 14 9/3/2008
Replacement parts for wood-fired heating system $300/yr
Labor costs are estimated at 242 hr/yr. This is a sunken cost, as firing will become part of the
duties of the maintenance staff of the school.
The total O & M costs for cordwood-fired hydronic heating system would be $805 to $1000/year.
Grant funds will not be used for any O&M expense. The purpose of the grant is to get a renewable
energy heating system into the school and on line as soon as possible.
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
The heat generated is not sold to anyone, but will just be used in the school. It is part of the operations of
the Coffman Cove School.
4.4.4 Cost Worksheet
Complete the cost worksheet form which provides summary information that will be considered
in evaluating the project.
Download the form, complete it, and submit it as an attachment. Document any conditions or
sources your numbers are based on here.
The budget form is attached. Costs are based upon numbers of similar construction in Southeast
Alaska (Attachment No. 6).
4.4.5 Business Plan
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.
Plan for Operations of the new Heating System
The cordwood-fired hydronic heating system will be just another heating source of the Coffman
Cove School. SISD will continue to fund a maintenance person who will be responsible for
stoking the hydronic heating unit on a daily basis and a plan in place to cover the operating and
maintenance tasks along with additional funds to cover associated costs for operation and
maintenance of the cordwood-fired hydronic heating system. The funds for purchasing the needed
wood source will be part of school O&M costs. These costs will result in a net annual savings of
over $23,865 in the first year of operations.
4.4.6 Analysis and Recommendations
Provide information about the economic analysis and the proposed project. Discuss your
recommendation for additional project development work.
Dan Parrent from the Juneau Economic Development Committee visited Howard Valentine
School in Coffman Cove in October and made a Reconnaissance; Resource Assessment/economic
analysis of the proposed project. His recommendation was to place a Garn or similar wood fired
hydronic heating unit (high efficiency, low emissions) at the site. His report is attached
(Attachment No. 9).
In addition, a simplified economic analysis was run on a spreadsheet to see how operations of the
system would work (Attachment No. 1). Using cordwood to take care of 85% of the fuel oil
needs of the school would result in a savings of $23,865 per year. Another spreadsheet (biomass

evaluation) was run to determine the total savings over time and the cost/benefit ratio. It was
found that using wood to heat the school resulted in a net saving of $1.28 million over 20 years.
It took about 9.8 years for the cost/benefit ratio to equal 1.0, which is an excellent indicator of the
economic viability of this project. The spreadsheets are found in Attachment No. 1.
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 (gal and $) 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 avoided cost of ownership)
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 annual fuel displacement is 8,500 gallons per year. Over 20 years, this would
amount to 170,000 gallons, or a net savings of $1.28 million. Assuming a life of 30 years for the
wood-fired heating unit, fuel saved would be 255,000 gallons, with a net savings of $3.63 million.
Non-economic public benefits would be a very low carbon footprint, and a much lower
dependence upon fossil fuels. Money used for fuel oil purchases would stay in the community,
providing local employment and income.
SECTION 6 – GRANT BUDGET
Tell us how much your total project costs. Include any investments to date and funding sources,
how much is requested in grant funds, and additional investments you will make as an
applicant.
Include an estimate of budget costs by tasks using the form - GrantBudget.xls
Provide a narrative summary regarding funding sources and your financial commitment to the
project.
The total project cost is $355,056. The grant fund request is $341,056. The bulk of the funding
for this project will come from an AEA Renewable Energy grant. SISD will provide $14,000 in
in-kind match for the project through SISD-paid labor for two SISD maintenance workers in the
construction of the facility.

Firing rates are based upon using 1 each Garn 3200 boiler (3200 gal water capacity).7. Wood fuel cost is expected to rise at a lower rate than that of fuel oil. In this case, it has been fixed at 1% above the rate of inflation, or 3.5% per annum in this analysis.5. Firewood is assumed to be all local hemlock, dried to 30% moisture content.6. Firewood is assumed to be 100 cu ft per cord, which includes cordwood bark.3. Labor rate is based upon an estimated rate of $20/hour, with 1 hr/day stoking on weekdays, 1 hr/day on Saturdays, and 1 hr/day on Sundays.2. Wood price estimate is from discussions with local consumers. Going rate is conservatively estimated at $175/cord from wood sources in USFS and private land holdings.1. Fuel oil cost is based upon October 2008 price of #2 heating oil from local fuel oil supplier.NOTES1. Labor time can be significantly reduced by use of equipment, such as a skid steer loader to help position pallets or skids of firewood for stoking.p,,py8. Wood fuel is assumed to replace 85% of the oil consumption at the facility.2. There should be a year's worth of wood on hand to ensure the 30% moisture content.

Please note that some fields might not be applicable for all technologies or all project
phases. Level of information detail varies according to phase requirements.
1. Renewable Energy Source
The Applicant should demonstrate that the renewable energy resource is available on a
sustainable basis.
Annual average resource availability. Forestry assessments show at least 5,000 cords of
firewood available in the area. This would
accommodate at least 61 years of harvest with SISD
demand, and this does not include sawmill waste.
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)

3. Proposed System Design
a) Installed capacity The wood-fired hydronic heater would be set up in a
separate building, and would consist one Garn® Model
3200 wood-fired hydronic heater, with a total water
capacity of 3,200 gallons. This boiler is sized to provide
60% of the peak building load with a six hour interval
between firings. The water capacity of the boiler is sized
so that it would serve as a thermal storage bank for the
facility, and would require intermittent firing. In this
configuration, it is anticipated that the wood-fired boiler
would meet 85% of the building’s heating needs.
b) Annual renewable electricity generation
i. Diesel [gal or MMBtu]
ii. Electricity [kWh]
iii. Propane [gal or MMBtu]
iv. Coal [tons or MMBtu]
v. Wood [cords, green tons, dry tons] Cordwood will provide 80% to 90% of the heat for the
facilities at 60% peak load. At a boiler efficiency of 75%,
this translated to 81cords of wood per year, or
approximately 118 green tons of cordwood
