6. Power Purchase/Sales Price
a) Price for power purchase/sale Wind-generated electricity will not be sold
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio For 8% annual fuel increase and 5% inflation:
Benefit/Cost=0.55 for 12 years. Benefit/Cost=1.1 for 18 years.
For 12% annual fuel increase and 5% inflation:
Benefit/Cost=.52 for 10 years. Benefit/Cost=1.14 for 15 years.
(See Attached “Hooper Bay WTP” Worksheets)
Payback Total Cost / (First Year’s Offset Fuel Cost – First Year’s O&M)
2,300,000 / (74,668-12,005)= 35 years
Note: Does not adjust for inflation
