These are the base charges in Eversource's commercial rate schedules that DEKALOS covers, from what NSTAR Electric Company d/b/a Eversource Energy 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 NSTAR Electric Company d/b/a Eversource Energy filed them. Riders, surcharges, taxes and the supply of the electricity itself are not included, so they are not a bill’s total, and a gap between the two is not by itself a mistake.
In this state you can buy the electricity itself from a supplier of your choice, so Eversource's schedules price delivery only. The supply half of the bill is priced by your supplier's contract or the utility's default service, and is not on this page.
