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. 916,600 kWh (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 3
ii. Rated capacity of generators/boilers/other 88, 88, 66 kW (peak rating)
iii. Generator/boilers/other type Diesel generators
iv. Age of generators/boilers/other All are 3 years old
v. Efficiency of generators/boilers/other Combined efficiency is 13 kWh/gal
b) Annual O&M cost (if system is part of the Railbelt grid, leave this section blank)
i. Annual O&M cost for labor $20,000 (estimated)
ii. Annual O&M cost for non-labor $5,000 (estimated)
c) Annual electricity production and fuel usage (fill in as applicable) (if system is part of the
Railbelt grid, leave this section blank)

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]
120 kW installed capacity – run-of-river hydro
87% capacity factor

4. Project Cost
a) Total capital cost of new system $2,711,000
b) Development cost $329,000 (includes $100,000 already committed)
c) Annual O&M cost of new system $22,200
d) Annual fuel cost zero
5. Project Benefits
a) Amount of fuel displaced for
i. Electricity 31,400 gal
ii. Heat 13,000 gal
iii. Transportation N/A
b) Current price of displaced fuel $4.00 per gal
$3.87 per gal (2010 AEA model price for heating fuel – used
for benefits calculations)
c) Other economic benefits Included in future fuel cost projections.
d) Alaska public benefits Significant other benefits, but not quantifiable in economic
terms.
6. Power Purchase/Sales Price
a) Price for power purchase/sale Est. retail utility rate with the project is $0.20 to 0.30 per
kWh. This includes revenue requirements for all utility costs.
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio With 50=year life, $4,993,600 / $2,450,500 = 2.04
Payback (years) $2.711M / $162,435 = 14.3 years
