An electrical utility is experiencing sharp power demand, which continues to grow at a high rate in a certain local area. Two alternatives to address this situation are under consideration. Each alternative is designed to provide enough capacity during the next 25 years. Both alternatives will consume the same amounts of fuel, so fuel cost is not considered in the analysis. The alternatives are detailed as follows:Alternative A: Increase the generating capacity now so that the ultimatedemand can be met with additional expenditures later. An initial investment of $30 million would be required, and it is estimated that this plant facility would be in service for 25 years and have a salvage value of $0.85 million. The annual operating and maintenance costs (including income taxes) would be $0.4 million.Alternative B: Spend $10 million now, and follow this expenditure withadditions during the 10th year and the 15th year. These additions wouldcost $18 million and $12 million. respectively. The facility would be sold25 years from now with a salvage value of $1.5 million. The annual operating and maintenance costs (including income taxes) initially will be $250,000 increasing to $350,000 after the first addition (from the 11th year to the 15th year) and to $450,000 during the final 10 years. (Assume that these costs begin one year subsequent to the actual addition.)If the firm uses 15% as a MARR, which alternative should be undertaken based on the present-worth criterion'?
