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 – Slana Wind Farm, Grizzly Lake Region, Alaska
The Applicant should demonstrate that the renewable energy resource is available on a
sustainable basis.
Annual average resource availability. Class 4-5 wind resource available (best in
wintertime when electrical demand is highest).
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)
2. Existing Energy Generation
a) Basic configuration (if system is part of the Railbelt1 grid, leave this section blank)
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)
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)
i. Electricity [kWh]
ii. Fuel usage
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]
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.

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 2.0 MW
b) Annual renewable electricity generation
i. Diesel [gal or MMBtu]
ii. Electricity [kWh] 5.256 million kW h for 2.0 MW of nameplate capacity.
iii. Propane [gal or MMBtu]
iv. Coal [tons or MMBtu]
v. Wood [cords, green tons, dry tons]
vi. Other
4. Project Cost
a) Total capital cost of new system $6.94 million
b) Development cost $0.3 million
c) Annual O&M cost of new system Direct O&M cost is three cents per kW hour
produced and sold.
d) Annual fuel cost Zero, nada, zip.
5. Project Benefits
a) Amount of fuel displaced for
i. Electricity 375,000 gallons per year
ii. Heat
iii. Transportation
b) Price of displaced fuel Liquid hydrocarbons – Price varies, but in 2008 the
price was approximately 25 cents per kWh. At an
average price of $3.50, this would be approximately
$1.31 million in fuel expenditure displacement.
c) Other economic benefits 1. Reduced air pollution in Slana area resulting in
reduced health care costs.
2. Some of the money that used to flow out of Slana to
Renewable Energy Fund

buy oil from non-Alaskan companies will now stay in
the local area and strengthen our economy.
d) Amount of Alaska public benefits If we save consumers just one cent per kWh over the
price of generating electricity using liquid
hydrocarbons: 2 MW Wind Farm X 25 percent
Capacity Factor X 8,760 hours per year = about 100
million kW hours per year or $43,800 per year in
savings, or $876,000 over 20 years.
6. Power Purchase/Sales Price
a) Price for power purchase/sale Close to APC’s actual avoided cost.
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio This grant will allow the project to proceed through to
construction and operation of the Slana Wind Project.
Payback Projected project commissioning is fall 2010.
