South Carolina Public Service Authority rate plans
2 residential plans are currently open to new customers. Some charge different prices depending on the hour — which is where most of the savings hide.
What does South Carolina Public Service Authority's residential rate cost?
South Carolina Public Service Authority files a single residential tariff, so there is no plan to choose between — everyone served here is on the same terms. That makes this page short on comparison and long on one question instead: what does that tariff actually do to a bill?
Priced hour by hour across a full year, a small apartment on this tariff comes to about $803 and a three-bedroom house with central air to about $1,333 — an effective 16.5¢ and 14.1¢ per kilowatt-hour once the fixed charge is spread across everything used.
With one plan and no hourly pricing, the only lever left is using less. Moving laundry or car charging to the middle of the night changes nothing here, which is worth knowing before you rearrange your evenings for no reason.
Expect the bill to swing with the weather rather than with anything you decide: the same house costs around $147 in July and $89 in February. Budget against the higher figure and the summer bill stops being a surprise.
Which plan would cost you least?
No bill upload, no sign-up. Tell us roughly what you use and what runs on electricity — we price every plan against the same household and show you the gap.
That adds up to 7,914 kWh a year. Compare it to the total on your bill and adjust until it’s close.
Same usage, different plan
$315a year
That is the gap between the cheapest plan you could be on — RESIDENTIAL GENERAL SERVICE SCHEDULE RG-25 — and the priciest. Not by using less power. By being billed differently for the same power.
| Plan | Per year | Vs best |
|---|---|---|
| RESIDENTIAL GENERAL SERVICE SCHEDULE RG-25One rate, every hour of the year. | $1,154 | — |
| RESIDENTIAL TIME-OF-USE RATE SCHEDULE RT-25Peak hits 6am–9am in Nov–Mar; 3pm–6pm in Apr–Oct — every day. | $1,470 | +$315 |
An estimate, not a quote. Supply charges move month to month, and your real usage pattern is not exactly this one. What it does show reliably is the gap between plans — both are priced off the same assumptions.
Before you switch anything
- 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.
