2024 EIA bundled residential average
20.22¢ per kWh
Historical annual average—not a current tariff.
EIA derives this average from the utility's reported residential revenue and sales. Your actual rate can differ because of tariffs, fixed charges, taxes, usage tiers, riders, time-of-use pricing, and other bill components.
What “bundled” means
Supply and delivery are reported together.
For this page, we only publish a provider headline when EIA reports bundled residential service. That makes this figure more useful than an energy-only or delivery-only component, but it still does not reproduce the provider's current rate schedule.
Data quality
Observed EIA record

Simple cost examples
What 20.22¢/kWh implies at common usage levels
These examples are simple usage × annual-average-price calculations. They are not predictions of a Delmarva Power bill.
Newer state context
Maryland's latest monthly residential average is 21.84¢/kWh.
That state figure is from June 2026, while the provider figure above is a 2024 annual EIA average. The periods and populations differ, so this is context rather than a direct price comparison. See the Maryland rate page →
