- Delmarva Power reported an average residential price of 17.23¢ per kWh across its bundled residential customers in the 2024 EIA Form 861 release. That is an annual average across all its residential customers, not a rate schedule, so an individual bill depends on the tariff, usage pattern and season.
- Is Delmarva Power expensive compared with the rest of Delaware?

- What is the average electricity bill for Delmarva Power customers?
- Dividing reported residential sales by residential customers gives about 10,603 kWh per customer per year. At the reported average price that implies roughly $1,827 a year, or about $152 a month. This is RateWatt's arithmetic on two EIA columns, not a figure EIA publishes.
- Who owns Delmarva Power?
- EIA classifies Delmarva Power as Investor Owned, a shareholder-owned company whose retail rates are set through a state regulatory commission. Nationally, the customer-weighted average across Investor Owned utilities was 18.37¢ per kWh in the 2024 Form 861 release.
