An integrated, combined cycle power plant produces 290 MW of electricity by gasifying coal. The capital
investment for the plant is $530 million, spread evenly over two years. The operating life of the plant is
expected to be 15 years. Additionally, the plant will operate at full capacity 74% of the time (downtime is 26% of
any given year). The MARR is 5% per year.
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?

Your company is considering the introduction of a new product line. The initial investment required for this project is $500,000, and annual maintenance costs are anticipated to be $45,000. Annual operating costs will be directly proportional to the level of production at $8.50 per unit, and each unit of product can be sold for $65. If the MARR is 15% and the project has a life of 5 years, what is the minimum annual production level for which the project is economically viable? The equipment can be sold for $80,000 at the end of five years.

The client is also considering purchasing a CAD/CAM system to replace its currently leased system (rather than renewing / entering a new lease contract). The new system will cost $450,000 to purchase and install. The system has an estimated life of five years, when it is expected to become obsolete, but it will have a salvage value of $25,000. The interest rate is projected to be 6% per year during the life of the project. a. Draw a cash flow diagram for the next four years for the existing system (leased system) and a separate cash flow diagram for the system that is being considered for purchase. b.

- Tom is considering purchasing a £20,500 car. After five years, he will be able to sell the vehicle for £7,500. Petrol costs will be £2,100 per year, insurance £650 per year, and parking £550 per year. Maintenance costs will be £900, rising by £400 per year thereafter. The alternative is for Tom to take taxis everywhere. This will cost an estimated £7,000 per year. Tom will rent a vehicle each year at a total cost (to year-end) of £900 for the family vacation, if he has no car. If Tom values money at 12% annual interest, should he buy the car? Use an annual worth comparison method (Perform all calculations using 5 significant figures and round any monetary answers to the nearest dollar).

The new machine is estimated to cost $33 million and will incur an additional $1.5 million per year in maintenance costs. The machine will produce annual savings of $4.5 million each year.

Maintenance is estimated to be a uniform gradient amount of $121 per year, with zero dollar for first year maintenance. The operation cost is estimated to be $0.3 per mile for 351 miles per month.

- The manager of Automated Products is contemplating the purchase of a new machine that will cost$300,000 and has a useful life of five years. The machine will yield (year-end) cost reductions toAutomated Products of $50,000 in year 1, $60,000 in year 2, $75,000 in year 3, and $90,000 in years4 and 5. What is the present value of the cost savings of the machine if the interest rate is 8 percent?arrow_forwardA company wants to renew its old natural gas fired boiler. According to the receivedprice offer, the new boiler is 400,000 TL in cash. The natural gas consumption of this boiler is 15m3/hour and the price of natural gas is 1.1 TL/m3. The annual real price escalation of natural gas is determined as 1%. The annual cost of the boiler operation and maintenance costs is 25,000 TL and the annual escalationvalue is 17%. By purchasing a new boiler, some of the costs of the old boiler will be saved. The old boiler has costs of 250,000 TL increasing by 15% annually. The new boiler will run for 6,000 hours a year. The annual discount rate is 24% and the annual inflation rate is 17%. Determine whether it is economically feasible to purchase the new boiler by using the annual worthmethod, taking into account the 10-year costs and savings. Use real ratesfor relevant parameters in calculations.arrow_forwardAn area can be irrigated by pumping water from a nearby river. Two competing installations are being considered. The MARR is 12% per year and electric power for the pumps costs $0.06 per kWh. Recall that 1 horsepower (hp) equals 0.746 kilowatts. (11.2, 11.3) a. At what level of operation (hours per year) would you be indifferent between the two pumping systems? If the pumping system is expected to operate 2,000 hours per year, which system should be recommended? b. Perform a sensitivity analysis on the efficiency of Pump A. Over what range of pumping efficiency is Pump A preferred to Pump B? Assume 2,000 hours of operation per year, and draw a graph to illustrate your answer.arrow_forward
- A car is needed for three years. Plans A and B for acquiring the car are being evaluated. An effective annual interest rate of 10% is to be used. Which plan is economically superior? Plan A: Lease the car for $0.25/mile (all inclusive) Plan B: Purchase the car for $30,000. Keep the car for three years. Sell the car after three years for $7200. Pay $0.14 per mile for oil and gas. Pay other costs of $500 per year.arrow_forwardBig Rock Brewery currently rents a bottling machine for $54,000 per year, including all maintenance expenses. The company is considering purchasing a machine K instead and is comparing two alternate options: option a is to purchase the machine it is currently renting for $165,000, which will require $22,000 per year in ongoing maintenance expenses, or option b, which is to purchase a new, more advanced machine for $250,000, which will require $19,000 per year in ongoing maintenance expenses and will lower bottling costs by $11,000 per year. Also, $40,000 will be spent upfront in training the new operators of the machine. Suppose the appropriate discount rate is 8% per year and the machine is purchased today. Maintenance and bottling costs are paid at the end of each year, as is the rental of the machine. Assume also that the machines are subject to a CCA rate of 25% and there will be a negligible salvage value in 10 years' time (the end of each machine's life).

He has found a somewhat newer vehicle (roughly the same functionality) that averages 26 mpg. He can sell his current minivan for $2800 and purchase the newer vehicle for $4,000. Assume a cost of gasoline $4.00 per gallon. How many miles per year must Jim drive if he wants to recover his investment in three years? Assume an interest rate of 6%, zero salvage value for either vehicle after three years, and identical maintenance cost.arrow_forward
