Rate against consumption: Delaware utilities

Each dot is one of the 9 Delaware utilities reporting both a residential price and residential sales in 2024, placed by its rank percentile within that group rather than its raw value, so one very large utility cannot flatten the rest. Bubble size follows customers served, rank-scaled so a utility with millions of customers cannot swamp the rest. Delmarva Power is highlighted. In Delaware the cheapest rate and the smallest implied annual bill happen to belong to the same utility, Sunrun Inc.; across the country they usually do not. 2×2 strategic matrix plotting 9 entities by Price rank percentile (100 = most expensive in state) (X) and Consumption rank percentile (100 = heaviest use) (Y), with a crosshair dividing the plot into four quadrants.

Delmarva Power reported an average residential price of 17.23¢ per kWh across its bundled residential customers in the 2024 EIA Form 861 release.

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?
