These are the base charges in NIPSCO's commercial rate schedules that DEKALOS covers, from what Northern Indiana Public Service Company LLC filed with its state regulator: the fixed charge, the demand charge and the energy charge, each with the date it took effect and the sheet it comes from. Where a sheet splits one charge into parts, the price here is their sum. The schedule on a bill is printed near the meter readings, as the rate, the rate schedule or the service classification.

What these prices leave out
These are base charges as Northern Indiana Public Service Company LLC filed them. Riders, surcharges, taxes and the fuel or power-cost adjustment are not included, so they are not a bill’s total, and a gap between the two is not by itself a mistake.
