SINGLE-PHASE SERVICE AP
When does peak hit on Aiken Electric Coop Inc’s SINGLE-PHASE SERVICE AP? The hour never matters here — only the season. Rates peak November–June.
- off-peak13.00¢
Weekends are off-peak all day — the cheapest time to run anything you can schedule.
What does SINGLE-PHASE SERVICE AP cost a year?
| Household | Uses | A month | Per year | Works out to |
|---|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $89 | $1,072 | 22.0¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $131 | $1,572 | 16.6¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $165 | $1,978 | 15.1¢ / 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.
What you actually pay
| Period | Rate | Applies when |
|---|---|---|
| off-peak | 13.00¢ up to 200 kWh10.85¢ up to 1000 kWh12.10¢ | midnight–midnight, July–October |
| off-peak | 13.00¢ up to 200 kWh10.85¢ up to 1000 kWh10.40¢ | midnight–midnight, November–June |
Plus a fixed charge of $1.35 per day — so longer months cost more before you use a single kWh.
Should you be on SINGLE-PHASE SERVICE AP?
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 $167 and February about $107. That $60 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.
There is a usage cliff to watch. The first 1000 kWh each month are billed at 10.8¢; past that line the rate steps up to 12.1¢ — 12% more for every unit after. The last kilowatt-hour of a heavy month is the expensive one, which is why cutting a little off a big month saves more than cutting the same amount off a small one.
Before a single kilowatt-hour moves, this plan charges $493 a year in fixed fees. On the apartment above that is 46% of the whole bill; on the house with a car charging in it, 25%. 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.

- Tiered billing for electricity: why the last kWh costs more
A cheap allowance, then a cliff. Where the cliff sits is the whole game.
- 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.
- Why is my electric bill so high in summer?
Usually three causes at once, and only one of them is your air conditioner.
