An integrated, combined cycle power plant produces 285 MW of electricity by gasifying coal. The capital investment for the plant is $570 million, spread evenly over two years. The operating life of the plant is expected to be 20 years. Additionally, the plant will operate at full capacity 75% of the time (downtime is 25% of any given year). The MARR is 6% per year. Solve, a. If this plant will make a profit of three cents per kilowatt-hour of electricity sold to the power grid, what is the simple payback period of the plant? Is it a low-risk venture? b. What is the IRR for the plant? Is it profitable?
QUESTION 1

- Oregon Ducks, Inc. is considering buying licenses for 12 megahertz of wireless spectrum in the 700 MHz range, which is suitable for delivering television to mobile phones. The 700 MHz signals can travel long distances and more easily penetrate walls and other obstacles. The acquisition cost is $300 million. In addition, because networks that operate in the 700 MHz range are less expensive to build than those in other portions of the spectrum, Ducks estimates annual costs of $24 million over the next 9 years and no salvage value. During the same period, the company expects to generate annual revenue of $40 million by offering television and video to mobile-phone users.

The treatment will cost $40,000 the first year, but process improvements will allow the costs to decline by $4,000 each year. As an alternative, an outside company will process the wastes for the fixed price of $20,000/year throughout the 8 year period, payable at the beginning of each year. Either way, there is no need to treat the wastes after 8 years. Use the annual worth method to determine how the wastes should be processed. The company's MARR is 13%.
