What Delaware's Electricity Data Tells Us
Households in Delaware are billed 16.57¢/kWh on average for residential power, per 2024 EIA data, covering 473.5K metered households in the state, running 0.5% ahead of the national residential average of 16.48¢/kWh. Commercial customers pay 12.20¢/kWh, and industrial customers are billed 8.49¢/kWh, reflecting the cost differentials that come from voltage level, load factor, and contract length across EIA Form-861 survey respondents. Residential customers consumed 5.2M MWh over the year, translating to roughly $857.3M in revenue for utilities, a useful yardstick for sizing local demand against the grid mix that serves it.
No fuel source matters more to Delaware's grid than natural gas, at 88.7% of in-state production, followed by solar at 7.8%, while coal adds another 3.0%. Tally solar, wind, hydro, geothermal, and biomass together and renewables reach 7.8% of Delaware's generation, a figure that matters because each renewable megawatt-hour displaces fuel costs that otherwise flow through to retail bills. Legacy fuels still dominate here, which tends to tie retail rates to commodity cycles.
Looking back across EIA records, residential prices in Delaware moved from 13.42¢/kWh in 2016 to 16.57¢/kWh in 2024, a 23.5% shift over that window. Ohio, Wisconsin, Illinois price out at a comparable level, a handy peer set for cross-checking. For anyone negotiating a supplier contract, weighing an energy-efficiency upgrade, or modeling a household budget, the combination of current rate, multi-year trend, and generation mix offers a sturdier footing than any single data point on its own.
