5. Project Benefits
a) Amount of fuel displaced for
i. Electricity 1,999,943 gallons displaced annually. Based on $4.25 gallon (will be
higher at completion date)
npv= $8,499,757, 3%, 50 years= $218,696,741.73
These numbers are included in the above figure of 218,696741.73
BASED ON 2008 DOLLARS THE NET PRESENT VALUE OF
THESE FUEL for KAKE ANGOON AND HONAH SAVINGS:
npv= $2,144,248, 3%, 50 YEARS=55,170,995.01
• BASED ON 2008 DOLLARS THE NET PRESENT VALUE
OF Wrangell and Petersburg FUEL SAVINGS:
npv= $472,024, 3%, 50 YEARS =$12,145,066.13
ii. Heat 86% diesel heating in Kake, Angoon and Hoonah (per CCHRC 2009
Alaska Housing Assessment)
81% diesel heating in Ketchikan, Petersburg, Wrangell (Extrapolated
and Based on documentation from CBJ 2007 Greenhouse Gas
inventory, March 2009)
50% conservative conversion from diesel to electricity over the 50
year life of the project
