tons]
24 cords/year (estimate)
vi. Other zero
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)
[kWh or MMBtu/hr]
120 kW installed capacity – run of river hydro
87% capacity factor

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 gallons
ii. Heat 13,000 gallons
iii. Transportation N/A
b) Price of displaced fuel $ 5.81 / gal (2011 projection)
c) Other economic benefits Embedded in fuel cost.
d) Amount of Alaska public
benefits
$0 in quantifiable economic terms
6. Power Purchase/Sales Price
a) Price for power purchase/sale Estimated utility rate to customers is $0.20 to
.30/kWh. This includes revenue requirements for
all utility costs.
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio With 50 year life, $5,600,000 / 2,355,500 = 2.38
Payback $2,590,000 / 252,200 = 10.3 years
