I'm trying to calculate what our bill would be assuming these factors:

Power draw would be 75,000 watts constant.
Rate is $ 0.04644 per kwh
Demand Charge, per kw $ 3.40

Demand charge kicks in after exceeding 7,500 KW month.

I calculated our farm would be using roughly 54,000 KW a month.

Can anyone who has intimate experience in calculating Kwh and demand able to figure out the monthly bill including demand charge on the figures I've posted please. Help would be really appreciated.
