ii. Heat 8,300 gal
iii. Transportation -
b) Current price of displaced fuel $4.00 per gal (actual price, 2010)
$3.99 per gal (2010 AEA model price for heating fuel – used
for benefits calculations)
c) Other economic benefits Value of other economic benefits, such as carbon taxes, are
included in AEA’s fuel cost projections.
d) Alaska public benefits No quantifiable benefits. Numerous indirect and intangible
benefits.
6. Power Purchase/Sales Price
a) Price for power purchase/sale Est. retail utility rate with the project is $0.12 to 0.64 per kWh
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio $4.02M / $3.10M = 1.30
Payback (years) $3.10M / $162,435 = 19.1 years
