Delmarva Power
Delmarva Power is investor owned serving 275,018 residential customers in Delaware, at an average residential price of 17.23¢ per kilowatt-hour.
That price is derived, and it is annual. It is total residential revenue divided by total residential sales in EIA’s 2024 survey — not a tariff, and not this month’s rate. For what a kilowatt-hour costs in Delaware right now, see the state page, currently 19.29¢.
What it reported, by service
| Service | Residential customers | Residential | Commercial |
|---|---|---|---|
| Bundled | 275,018 | 17.23¢ | 16.54¢ |
| Delivery | 26,932 | 7.17¢ | 2.79¢ |
A utility can file bundled service and delivery-only service separately. A delivery-only price excludes the energy itself, so the two are not comparable and are not ranked against each other.
How often the power goes out
| Minutes without power per customer, 2024 | 127.0 minutes (SAIDI, including major event days) |
|---|---|
| Interruptions per customer | 0.77 (SAIFI) |
| Excluding major event days | 68.0 minutes the figure utilities are benchmarked on |
| Reported under | IEEE standard |
The headline figure includes major event days, because a customer who lost power for three days in a storm lost power for three days. See how this compares nationally.
