Renewable Energy Fund Round 5
Project Cost/Benefit Worksheet
RFA AEA12-001 Application Cost Worksheet Page 1 7-1-11
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.
1. Renewable Energy Source
The Applicant should demonstrate that the renewable energy resource is available on a
sustainable basis.
Annual average resource availability. 120 cfs at 47% availability = 21.7 GWh of net
energy output for average water year.
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 On railbelt, NA.
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]
ii. Electricity [kWh]
iii. Propane [gal or MMBtu]
iv. Coal [tons or MMBtu]
v. Wood [cords, green tons, dry tons]
vi. Other
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.

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]
5.4 MW of installed capacity Run-of-river hydroelectric
installation. 47% capacity factor
b) Proposed annual electricity or heat production (fill in as applicable)
i. Electricity [kWh] 21,700,000 kWh per year
ii. Heat [MMBtu]
c) Proposed annual fuel usage (fill in as applicable)
i. Propane [gal or MMBtu] NA
ii. Coal [tons or MMBtu] NA
iii. Wood [cords, green tons, dry tons] NA
iv. Other NA
4. Project Cost
a) Total capital cost of new system $14,700,000
b) Development cost $ 2,000,000
c) Annual O&M cost of new system $ 300,000
d) Annual fuel cost $0
5. Project Benefits
a) Amount of fuel displaced for
i. Electricity 21,700,000 kWh/year
ii. Heat NA
iii. Transportation NA
b) Current price of displaced fuel $0.09 per kWh
Per 2011 AEA forecasts for southern railbelt
c) Other economic benefits Included in future fuel cost projections
d) Alaska public benefits $42,000,000 (per AEA model)
6. Power Purchase/Sales Price
a) Price for power purchase/sale AEA 2011 model for southern railbelt. ($0.09 per kWh in 2014)
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio With 50 year life, $42M / $13.2M = 3.18
Payback (years) $16.7M / $2.0 M = 8.4 years
