Dearest — July 2025
$208
Cheapest — October 2025

The dearest month costs $88 more than the cheapest — 74% higher and it is air conditioning that does it. Delaware runs about 1,200 cooling degree days a year, so the summer bill is where any efficiency gain shows up.
Why the bill is what it is
A bill is a rate multiplied by a quantity, and in Delaware the amount of electricity used is doing most of the work. Comparing your own bill to this figure only tells you something once you know which of the two you could actually change — the rate is largely fixed, the quantity is not.
Heating and cooling are usually the largest movable part. Whether that means a heat pump, a more efficient air conditioner, or neither depends on Delaware's prices rather than on general advice.
Figures are twelve-month averages across 481,756 residential accounts in Delaware, from the US Energy Information Administration. They describe the state, not your house — square footage, insulation and what you keep the thermostat at move an individual bill a long way. See the Delaware rate page for the underlying prices.
