Delaware vs U.S. average bill
Delaware's typical residential bill estimate is higher than the U.S. average by $1.53 per month (0.9%).
Is this what you'll actually pay?
It's a fair benchmark, not a forecast. We take Delaware's average rate of 18.48 ¢/kWh and apply it to 900 kWh a month at the all-in average rate, which comes to $166.32. That rate already includes delivery, fixed charges, and utility fees; locally billed taxes vary by area.
Your own bill can land well above or below that, depending on how much you run the air conditioning, how you heat your home and water, your home's size, and how your utility designs its rates.

Why is my Delaware electric bill higher than the average?
Usage is the biggest reason: air conditioning, electric heat, and water heating can push a home far past 900 kWh a month. Rate design matters too. In Delaware, Delmarva Power's standard residential tariff carries a $13.50 fixed monthly charge plus 8.56¢/kWh in riders, so a low-usage home pays more per kWh than the average implies and a high-usage home pays less.

Source & Method
Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: July 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility.
