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. unlimited
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel) Biomass fuel
2. Existing Energy Generation
a) Basic configuration (if system is part of the railbelt grid, leave this section blank)
i. Number of generators/boilers/other This is a new construction project which will install
2 – WHS GARN Heating Units
ii. Rated capacity of generators/boilers/other 250,000 BTUs per hour x 2 units = 500,000 BTUs
Storage BTU capacity x 2 units =2.4 million BTUs
iii. Generator/boilers/other type
iv. Age of generators/boilers/other
v. Efficiency of generators/boilers/other 84% average efficiency when wood is at 20%
humidity
b) Annual O&M cost
i. Annual O&M cost for labor To maintain boilers represents 5% of existing maintenance
personnel budget. Solar installation is very minimal.
ii. Annual O&M cost for non-labor $ 1,000 per year to clean out and inspect boilers
c) Annual electricity production and fuel usage (fill in as applicable)
i. Electricity [kWh] .75 per kilowatt estimated $3,000-$4,000 per month under conventional
electrical use.
ii. Fuel usage (if system is part of the Railbelt grid, leave this section blank
Diesel [gal]
Other
iii. Peak Load
iv. Average Load
v. Minimum Load
vi. Efficiency
vii. Future trends
d) Annual heating fuel usage (fill in as applicable)
i. Diesel [gal or MMBtu] 12,000 gallons heating fuel projected in business model
with conventional oil fired boilers. It will be -0- with
Biomass and Solar Thermal Use Systems proposed to be
installed in new facility.

kilowatts per year. Based on average of 4.4 hrs daylight
for interior region x 63 panels x 365 days
Biomass System handles domestic heating and hot water
use.
b) Annual renewable electricity generation
i. Diesel [gal or MMBtu]
ii. Electricity [kWh] 13,153,140 kilowatts /year
iii. Propane [gal or MMBtu]
iv. Coal [tons or MMBtu]
v. Wood [cords, green tons, dry tons]
vi. Other

b) Development cost 0
c) Annual O&M cost of new system
d) Annual fuel cost 12, 500 ( 50 cords )
5. Project Benefits
a) Amount of fuel displaced for
i. Electricity Replaces 35% of electrical costs
ii. Heat Replaces 10-12,000 gallons of fuel
iii. Transportation
b) Price of displaced fuel 7.00 x 10,000 gallons – 70,000 – 84,000 dollars
c) Other economic benefits Jobs in community for suppliers, and cheaper costs for
seniors ( on fixed incomes) to live in the facility.
