Renewable Energy Fund Round 4
Project Cost/Benefit Worksheet
RFA AEA11-005 Application Cost Worksheet Page 1 7-21-10
Please note that some fields might not be applicable for all technologies or all project
phases. The level of information detail varies according to phase requirements.
Note to RE Fund Selection Committee from applicant: This proposal calls for feasibility
studies of wood-fired district heating systems in public buildings in eight rural Alaska
communities. The proposal does not include construction, installation, or operation of any
energy system. Most fields on this form are not relevant. The applicant has included certain
information based on hypothetical installation of a wood heating system only for discussion
purposes. None of this information should be assumed to represent actual project costs and/or
savings.
1. Renewable Energy Source
The Applicant should demonstrate that the renewable energy resource is available on a
sustainable basis.
Annual average resource availability. The wood consumption of a Garn-style boiler is
minimal compared to forest resources available to
these Interior Alaska communities. The wood
heating system at the washeteria in Tanana, for
example, relies extensively on driftwood alone. See
Section 4.1 of proposal narrative for more
information about the sustainable wood supply and
applicant’s plans for forest management and wood
harvest strategy.
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)
2. Existing Energy Generation and Usage
a) Basic configuration (if system is part of the Railbelt1 grid, leave this section blank)
i. Number of generators/boilers/other Oil-fired boilers (#1 heating oil), some recovered
waste heat, some traditional wood stoves, low
number of electric heaters.
ii. Rated capacity of generators/boilers/other
iii. Generator/boilers/other type
iv. Age of generators/boilers/other
v. Efficiency of generators/boilers/other
b) Annual O&M cost (if system is part of the Railbelt grid, leave this section blank)
i. Annual O&M cost for labor Varies between different communities and buildings.
ii. Annual O&M cost for non-labor Varies.
c) Annual electricity production and fuel usage (fill in as applicable) (if system is part of the
Railbelt grid, leave this section blank)
i. Electricity [kWh]
1 The Railbelt grid connects all customers of Chugach Electric Association, Homer Electric Association, Golden Valley Electric
Association, the City of Seward Electric Department, Matanuska Electric Association and Anchorage Municipal Light and Power.

iii. Peak Load
iv. Average Load
v. Minimum Load
vi. Efficiency
vii. Future trends
d) Annual heating fuel usage (fill in as applicable)

ii. Electricity [kWh] Varies.
iii. Propane [gal or MMBtu] Varies.
iv. Coal [tons or MMBtu] n/a
v. Wood [cords, green tons, dry tons] Varies, but it can be assumed that one cord of white
spruce delivers an equal amount of heat as 85.5 gallons
of #1 fuel oil, depending on rates of burn efficiency.
vi. Other
3. Proposed System Design Capacity and Fuel Usage
(Include any projections for continued use of non-renewable fuels)
a) Proposed renewable capacity
(Wind, Hydro, Biomass, other)
[kW or MMBtu/hr]
Biomass, wide range of Btu/hr rates depending on
particular building(s)
b) Proposed annual electricity or heat production (fill in as applicable)
i. Electricity [kWh]
ii. Heat [MMBtu]
c) Proposed annual fuel usage (fill in as applicable)
i. Propane [gal or MMBtu]
ii. Coal [tons or MMBtu]
iii. Wood [cords, green tons, dry tons] Varies widely depending on building(s).
iv. Other
4. Project Cost
a) Total capital cost of new system n/a
b) Development cost n/a
c) Annual O&M cost of new system n/a
d) Annual fuel cost ~ $250 to $350 per cord of wood (average)
5. Project Benefits
a) Amount of fuel displaced for
