What does Residential Service cost a year?

HouseholdUsesPer yearWorks out to
Apartment

One or two people, no central air, no electric heat

4,866 kWh$88518.2¢ / kWh
Family home

Three or four people with central air conditioning

13,103 kWh$2,10916.1¢ / kWh

Estimates, not quotes. We run three made-up but realistic households through this tariff hour by hour for a full year — including the way air conditioning loads the afternoon and an EV loads the small hours. Your own bill depends on when you actually use electricity, which is exactly the thing a per-kWh number hides.

Plus a fixed charge of $13.5 per month.

Should you be on Residential Service?

The hour of day does not change what you pay here — the month does. Running the same house through the full year, July costs about $176 and February about $103. That $73 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.

Before a single kilowatt-hour moves, this plan charges $162 a year in fixed fees. On the apartment above that is 18% of the whole bill; on the house with a car charging in it, 8%. Fixed charges are invisible in a cents-per-kWh comparison and they punish small users hardest — if you use very little electricity, the headline rate is the least important number on this page.

How it compares to Delmarva Power’s other plans

Measured against the other residential plans this utility files, a family home lands 4th cheapest of 5. The cheapest option, Residential Space Heating Service, would run about $929 a year less.
