1. The problem statement, all variables and given/known data EXCEL TABLE AS ATTACHMENT a.) What is the kWh used for this day? b.) Assuming that this is the peak day for the previous year and TOD rates shown below apply, what is the energy usage and demand charges for this day? c) What would be the change in charges if the second occurrence of process 2 was moved to 45 minutes later? 2. Relevant equations None provided. 3. The attempt at a solution For part a. I simply added up all the kwH used throughout the day from the excel table kwH used for the day: 9497.28 For part b. I calculated the energy usage by multiplying the cost per kwH by the total kwH. Energy Usage I got: $.03773 * 9497.28 = $358.33 I found the demand charge by adding up the total kwH from 1pm to 7pm (peak demand), and replacing the cost of kwH with the maximum load charge since the question stated "assuming peak day". Demand Charge I got: $4.55 * 3341.61 = $15,204.33 For part c. I believe we go from 1:00pm to 1:45pm for process 2 (since this is the second occurrence period); however, I don't know what the change in charges would be since it seems it is during the intermediate period regardless. So no change? Appreciate any help, if you are familiar with this subject I do have a few other relevant questions so I am in search of an online tutor, thank you.
