Your firm has a manufacturing plant located on a river in up-state New York. The plant gets most of its electricity used for manufacturing from an electric generator powered by hydro power from that river. Any amount of electric power required by the plant that is not supplied by the generator is obtained by buying electricity from the local municipal power district at a cost of $.02 per kWh. Your plant typically uses 20,000,000 kWh spread very evenly over a year. The required rate of return is an effective annual rate of .05 (5%). Unfortunately, your generator just failed. You have been asked to consider two replacement generators. The Efficerator, which costs $3, 500,000, can produce 18,000,000 kWh per year. The alternative, called the Cheaperator, only costs $2, 250,000, but can only produce 15,000,000 kWh per year. In addition, The Efficerator has an expected life of 30 years and requires $40,000 of regularly scheduled maintain at the end of each year, while the Cheaperator, which also has an expected life of 30 years requires $50,000 of regularly scheduled maintenance at the end of every year. The Cheaperator also requires a major maintenance procedure after every 10 years of service (there is no need to do this service at the end of its life). The other issue with these models is that the Efficerator will cost $150,000 to remove at the end of its life, but the Cheaperator will cost $260,000 to remove at the end of its life. Which generator should you select? Why
