An electrical utility needs to generate 6,700 megawatts of electricity today. It has five generators (A, B, C, D, and E). If any electricity is generated by a given generator, that generator must be started up and a fixed start-up cost is incurred. There is an additional cost for each megawatt generated by a generator. These costs, as well as the maximum capacity of each generator, are shown in the following table. A B Fixed start-up cost $3,000 $2,000 Cost per megawatt/day generated Maximum capacity (MW/day $5 $4 $2,500 $6 D $1,500 $6 $1,000 $7 2,100 1,800 2,500 1,500 3,000 Click here for the Excel Data File Formulate and solve this model on a spreadsheet. a. Determine the minimum cost plan that meets the electrical needs for today. Note: Leave no cells blank. Enter "O" wherever required. Startup generator? (Enter 1 if "Yes", 0 if "No") Megawatt/day b.
