Your engineering firm has been tasked with examining generation alternatives for an electric utility. The utility needs to add 250 MW of average power production, and is considering solar photovoltaics (PV). The utility needs this new facility to generate 2.19 million MWh each year. (Note: 250 MW X 8760 hrs/yr = 2.19 million MWh/yr) The utility charges $120 for every MWh sold, and this price is projected to increase 1% annually for the foreseeable future. Costs associated with solar photovoltaics (PV) are given in the table below. Assume an interest rate of 5%. Solar PV Investment cost ($/kW) 1500 Year 1 maintenance cost ($/kWyr) 10 Annual maintenance cost increase 1% Availability* 25% Expected life (yr) 20 a 1000 kW = 1 MW * Availability represents the amount of electricity generated that is actually available for distribution. For instance, if the facility needs to deliver 250 MW of power, but only 30% of the capacity is available on average, then 250 MW / 0.30 = 833 MW installation would be required. Calculate the following costs associated with solar photovoltaics (PV) use: a. (1 pt) How much MW of power should the Solar PV plant be sized for? b. (1 pt) What is the initial investment cost for this size plant? c. (1 pt) What is the annual maintenance cost for this plant expressed as a present worth? d. (1 pt) What is the annual maintenance cost for this plant expressed as an annual worth? e. (1 pt) What is the expected income of this plant in year 1? f. (1 pt) What is the present worth of your expected incomes over the 20 year lifetime? Your engineering firm has been tasked with examining generation alternatives for an electric utility.
