The delivery charge includes components for maintaining and upgrading the grid, funding critical customer services and programs, taxes and other state and federally-mandated charges.
Some of these charges are calculated based on the amount of energy you use. We multiply your usage (measured in kilowatt hours) by the rate to determine your charge. Using less energy can lower these charges.
