Consider that an engineer needs to determine whether or not to power a facility with a microgrid. The initial cost of the microgrid is $1 million but it yields the following net savings when compared with the option of powering the system from the grid: $75,000 in year 1, $150,000 in year 2, $225,000 in year 3, $250,000 in years 4 and 5, $200,000 in year 6, $75,000 in year 7, $150,000 in year 8, and $200,000 in years 9 and 10. If the annual discount rate is 11.55%, what is the net present value of the investment. In your calculations for the net present value , assume the initial investment is negative, and the incomes in years 1-10, are positive. Choose below, and upload your calculations to receive credit for this problem. Hint, using Excel or Mathcad will greatly simplify your work. O 523989 -835 2340 -62 -11545 45041 12
