Project Cost a) Total capital cost of new system $100,015,360 (LESS 3,403,050) DEVELOPMENT COST)= $94,939,886 b) Development cost 3,403,050 c) Annual O&M cost of new system 300,000 d) Annual fuel cost 0 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 in 2016 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 Angoon 130,261 gallons annually Hoonah 377,202 gallons annually Kake 179,405 gallons annually Ketchikan 8,669,806 gallons annually Petersburg 1,491,411 gallons annually Wrangell 1,904,205 gallons annually TOTAL 12,752,290 GALLONS DISPLACED ANNUALLY Renewable Energy Fund Round 3 Project Cost/Benefit Worksheet RFA AEA10-015 Application Cost Worksheet Page 4 10-7-09 Assume a $4.25 per gallon rate in 2016 (conservative) Npv= $54,197,232, 3%, 50 years=$1,394,481,989.19 iii. Transportation Advent of electrical vehicle conversion will displace additional fuel . Estimate is 1,000,000 gallons at $4.25 by 2016 when project comes on line Npv=$4,250,000,3%, 50 years=$109,351,497.03 b) Price of displaced fuel 2016 construction completion date $4.25 gallon conservative c) Other economic benefits Savings in State of Alaska PCE subsidies to Angoon, Kake and Hoonah PCE Subsidy per year based on 2008 IPEC subsidy for Angoon, Kake and Hoonah: $1,177,678 NPV @ 3% 50 years= $30,301,376.50 d) Amount of Alaska public benefits Reduction in unemployment, increase in standard of living, increase in SE Economic development due to low cost energy, reduction in crime and social problems associated with high unemployment and lack of economic opportunity. $1808 per ratepayer of Angoon, Hoonah, and Kake for just the increase in the standard of living by paying less for energy per year. Total benefits would take a detailed study. 6. Power Purchase/Sales Price a) Price for power purchase/sale Target:9 cents per kWh in-state. Range of final price for power purchase sale will be dependent on grant financing. Debt financing will provide a rate in a range of 9 to 14 cents per kWh 7. Project Analysis a) Basic Economic Analysis Project benefit/cost ratio ($1,722,530,228+$30,301,376.50)/$ 100,015,360 =17.52 Payback 100,015,360/ free cash flow to be determined = payback period. Highly dependent on type of grant, financing, loan terms
