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: Fourth of July Creek Hydroelectric
Project
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, biomass fuel)

a) Total capital cost of new system $16,700,000
b) Development cost $ 850,000
c) Annual O&M cost of new system $ 300,000
d) Annual fuel cost Zero
5. Project Benefits
a) Amount of fuel displaced for
i. Electricity 184,000 MCF of Natural Gas per year
ii. Heat N/A
iii. Transportation N/A
b) Price of displaced fuel $1,676,000 per year (at $9.00 per MCF)
c) Other economic benefits $ 280,000 per year
d) Amount of Alaska public
benefits
$0 in quantifiable economic terms
6. Power Purchase/Sales Price
a) Price for power purchase/sale $0.071/kWh
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio 50,200,000 / 16,700,000 = 3.01
Payback 16,700,000 / 1,956,000 = 8.5 years
