Stationary Fuel Cells: Economics 101 Income tax consequences for capital intensive projects Load factor issues Risk Jane Price Hill, P. E.February 13, 2003

Stationary Fuel Cells: Economics 101 Expenses can be written off for tax purposes in the year in which they are incurred: $Fuel $O&M $Property taxes $Insurance $Labor $Electricity Jane Price Hill, P. E.February 13, 2003 Capital expenditures must be written off over many years: $Equipment $Installation $Engineering $Freight $Site preparation $Construction

Stationary Fuel Cells: Economics 101 While there are several acceptable ways to evaluate capital costs, there is one common method which is fundamentally inadequate: Jane Price Hill, P. E.February 13, 2003 Annualized capital cost = Capital Cost Equipment Life

Stationary Fuel Cells: Economics 101 Time value of money Income tax consequences for capital expenditures versus expenses Salvage value and tax consequences of salvage Jane Price Hill, P. E.February 13, 2003 Because this method ignores:
