5. Project Benefits
a) Amount of fuel displaced for
i. Electricity
ii. Heat 45,000 gallons (90% of current consumption)
iii. Transportation
b) Price of displaced fuel $240,750 based on FY2009 fuel price of $5.35/gallon
c) Other economic benefits Future economic benefit for carbon credits, should the US
implement a plan.
d) Amount of Alaska public benefits $12.58 million in savings over 30 years based on a
conservative 5% annual fuel oil price escalation, using the
FY2009 rate of $5.35/gallon.
6. Power Purchase/Sales Price
a) Price for power purchase/sale No power will be purchased/sold under this project
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio Assuming 5% fuel inflation: 0.26 in 5 yrs; 0.76 in 12 yrs; 1.65 in 20 yrs,
using FY2009 fuel price of $5.35/gallon.
Payback Simple payback = $3,652,680 / $167,225 annual savings =
22 years. Note that this calculation assumes fuel at the FY2009 rate of
$5.35 per gallon, and does not allow for inflation.
