A Municipality needs a new fleet of busses. They have a choice between a diesel fuel powered fleet and a natural gas powered fleet. The Diesel fuel fleet has an initial cost of $50,000,000. The annual maintenance is $1,000,000 per year, each and every year of the 10 years life expectancy of the fleet. In addition, there will be a carbon emissions tax that starts at $250,000 in year 2, and increases by $250,000 each and every year after that. At the end of the ten years the busses can be sold for $5,000,000. The Natural Gas fleet can be purchased for $60,000,000. The annual maintenance is $800,000 per year. There is no carbon tax on the fleet. However, there is a 65% chance of a $5,000,000 one time Special Maintenance cost at year 7. Because of certain toxic parts on the bus engines, the municipality will have to pay $5,000,000 and the end of the bus life to dispose of them. Use the present value approach to determine which fleet is more cost effective. The cost of money is 6% (DO NON- Annualized method).
