What does Residential Service cost a year?
| Household | Uses | Per year | Works out to |
|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $966 | 19.8¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $1,762 | 18.6¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $2,395 | 18.3¢ / 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
| Period | Rate | Applies when |
|---|---|---|
| peak | 17.37¢ | midnight–midnight, October–April |
| off-peak | 17.34¢ | midnight–midnight, May–September |
Plus a fixed charge of $10.07 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 $201 and February about $114. That $87 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 $121 a year in fixed fees. On the apartment above that is 13% 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.
How it compares to Southern Maryland Elec Coop’s other plans

Four kinds of charge, only two of which you can do anything about.
- 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.

Usually three causes at once, and only one of them is your air conditioner.
