What does Residential Service Time of Use cost a year?
| Household | Uses | Per year | Works out to |
|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $977 | 20.1¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $1,797 | 19.0¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $2,345 | 17.9¢ / 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.
What you actually pay

Should you be on Residential Service Time of Use?
This is a time-of-use plan, which means the clock decides your bill as much as the meter does. At the worst hour you pay 27.5¢ a kWh; at the best hour, 14.5¢ — 1.9× apart for identical electricity.
That gap is worth real money only if you can move load into it. Every kilowatt-hour a day you shift from 2pm to midnight is about $47 a year. A dishwasher run is roughly 1.5 kWh; an EV commute charge is 8 to 12. If your day is fixed — you are home in the evening and the air conditioner runs when it runs — a plan like this costs you more, not less.
Before a single kilowatt-hour moves, this plan charges $121 a year in fixed fees. On the apartment above that is 12% of the whole bill; on the house with a car charging in it, 5%. 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.
Expect the bill to move with the calendar. The same family home costs about $204 in July and $118 in February — a $86 spread driven by heating and cooling far more than by anything you chose. Budget against the July figure, not the average, and a summer bill stops being a surprise.
How it compares to Southern Maryland Elec Coop’s other plans
Measured against the other residential plans this utility files, a family home lands 3rd cheapest of 3. The cheapest option, Residential Service, would run about $1,065 a year less.
Against Residential Service, which looks like the plan you land on by default, this one comes out $35 more per year (2%). We infer the default from the tariff structure rather than a flag in the data, so confirm it against your own bill before you switch.
If this is new to you
- What is a time-of-use electricity rate?
The same kilowatt-hour, priced differently depending on when you use it.
- Should you switch to a time-of-use electricity plan?
A wide peak-to-off-peak gap is a lever, not a saving. Levers need something to move.
- When should you charge an electric car at home?
The single biggest load most homes can move, and the easiest to automate.
- Why is my electric bill so high in summer?
Usually three causes at once, and only one of them is your air conditioner.
