(b) (5 pts) For the natural gas power plant, what is the present value of the 1 maintenance cost (\$) 2. fuel cost (\$) 3. electricity revenue (\$) 4 and salvage value ($) 5 based on these costs, what is the net present worth in terms of benefits minus costs (\$)? (c) (3 pts) For the coal power plant, what is the 1. EUAC? 2. EUAB? 3 EUAW? (d) (3 pts) For the natural gas power plant, what is the 1. EUAC? 2 EUAB? 3. EUAW? We are an electric utility company that is going to build a new power plant We are choosing between a coal-fired power plant and a natural gas-fired power plant The coal-fired power plant will be based on a pulverized coal wall-fired furnace with supercntical steam cycle, and will burn a high sulfur bituminous coal The coal power plant will have low NO, bumers, overfire air, selective catalytic reduction, electrostatic precipitation, and flue gas desulfurization. The natural gas fired power plant will be based on a steam-cooled heavy-duty gas turbine combined cycle design, with selective catalytic reduction for NOk control The estimated service life of the coal-fired power plant is 50 years. The estimated service life of the gas turbine combined cycle plant is 50 years We will use a planning horizon of 50 years. Both power plants are designed to be 500MW capacity The coal power plant has an initial capital cost of $1,000 million, an annual maintenance cost of $24 million per year that increase 2% a year, an annual fuel cost of $48345 million per year, and a salvage value of $40 million at the end of 50 years The coal power plant will generate 241 billion kWh of electricity each year, which will bring in electricity revenue of $15659 million per year The natural gas fired power plant has an initial capital cost of $300. million, maintenance cost of $45 million per year that increase $500,000 a year, an annual fuel cost of $54.075 million por year, and no salvage value The natural gas power plant will generate 2.63 billion kWh of electricity each year, which will bring in electricity revenue of $170,82 milion per yeat For the following questions, use an interest rate of 10 percent, compounded annually For this problem, report your answer in terms of millions of dollars with two decimal places (e.g., 26,520,000 would be entered as 26.52). (a) (5 pts) For the coal power plant, what is the present value of the 1. maintenance cost (\$) 2 fuet cost (\$) 3 electricity revenue (\$) 4 and salvage value (\$) 5 based on these costs, what is the net present worth in terms of benefits minus costs (\$)? (e). (2 pts) Which power plant is the best choice from an economic perspective? Coal Power Plant Natural Gas Power Plant
