Application Cost Worksheet
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. The average annual heat source availability is
dependent on the operating characteristics of the
host’s gas turbine. This information will not be
available until the first phase of this project is
complete, which is the purpose for obtaining the
funding in this grant application.
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)
The recovered energy generation is dependent on the waste heat exhaust stream from the host-
owned gas turbine.
2. Existing Energy Generation
a) Basic configuration (if system is part of the Railbelt1 grid, leave this section blank)
It will not be known until the reconnaissance on the project site is completed whether the project
will be located within the Railbelt grid and the details of the project design.
i. Number of generators/boilers/other
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)
It will not be known until the reconnaissance on the project site is completed whether the project
will be located within the Railbelt grid and the details of the project design.
i. Annual O&M cost for labor
ii. Annual O&M cost for non-labor
c) Annual electricity production and fuel usage (fill in as applicable) (if system is part of the
Railbelt grid, leave this section blank)
It will not be known until the reconnaissance on the project site is completed whether the project
will be located within the Railbelt grid and the details of the project design. Regardless of the

location, the recovered energy generation facility will not consume any fuel for the production of
electricity. Assuming a typical installation and operational characteristics and performance of
an LM2500 gas turbine, below would be the estimated production and fuel usage figures:
i. Electricity [kWh] 50,000,000 annually
ii. Fuel usage
Diesel [gal] none
Other none
iii. Peak Load 6500kW
iv. Average Load 5500kW
v. Minimum Load 5000kW
vi. Efficiency 20%
vii. Future trends Dependent upon host’s operations
d) Annual heating fuel usage (fill in as applicable) n/a
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]
vi. Other
3. Proposed System Design
a) Installed capacity 5800kW
b) Annual renewable electricity generation
i. Diesel [gal or MMBtu] n/a
ii. Electricity [kWh] 50,000,000
iii. Propane [gal or MMBtu] n/a
iv. Coal [tons or MMBtu] n/a
v. Wood [cords, green tons, dry tons] n/a
vi. Other
4. Project Cost
a) Total capital cost of new system $27,250,000
b) Development cost $750,000
c) Annual O&M cost of new system tbd
d) Annual fuel cost There is no fuel cost. However, there would be expected
to be some payment made for the exclusive use of the

waste heat stream provided by the host.
5. Project Benefits
These calculations would all be dependent upon the offset that is being made by the recovered
energy generation facility. In the event it is offsetting electric grid power, then the calculation
would be based upon the fuel type of the generation which is offset by the purchasing utility. In
the event it would be offsetting the installation of a diesel fired generator to provide electricity,
then the offset cost would be tied to diesel oil costs. The figures and benefit calculation requested
below cannot be provided until the reconnaissance work is completed on the project and an
evaluation of the electric grid and electricity prices has been evaluated.
a) Amount of fuel displaced for
i. Electricity 500,000MMBTU annually
ii. Heat
iii. Transportation
b) Price of displaced fuel
c) Other economic benefits
d) Amount of Alaska public benefits
6. Power Purchase/Sales Price
The power sales price below cannot be provided until the reconnaissance work is completed on
the project and an evaluation of the electric grid and electricity prices has been evaluated.
a) Price for power purchase/sale
7. Project Analysis
The economic analysis below cannot be performed until the reconnaissance work is completed
on the project, an evaluation of the electric grid and electricity prices has been evaluated, and
the final design has been completed to determine the actual capital cost for this project.
a) Basic Economic Analysis
Project benefit/cost ratio
