What does Wisconsin Public Service cost at a normal month’s usage?
A household using 1,000 kWh a month pays about $1,731 a year on the cheapest of the 4 plans we can price here — Residential Seasonal Rg-1 — and $2,090 on the priciest. Same house, same wires.
| A month of | Cheapest, a year | On which plan | Priciest |
|---|---|---|---|
| 500 kWh | $873 | Residential Seasonal Rg-1 | $1,153 |
| 1,000 kWh | $1,731 | Residential Seasonal Rg-1 | $2,090 |
| 2,000 kWh | $3,449 | Residential Seasonal Rg-1 | $3,966 |
The same plan is cheapest at every level of use here, so the answer does not turn on how much you use. Estimates from the filed tariff, priced hour by hour on a household with central air — not a quote.
How much does the plan you pick actually matter here?
Run the same three-bedroom house with central air through every plan Wisconsin Public Service Corp files, and the bill lands anywhere between $1,366 and $1,692 a year. That $325 spread is not a difference in electricity — it is the same kilowatt-hours, from the same wires, priced under different rules. Nobody sends you a letter when you are on the wrong side of it.
The plan most households land on by default, Residential Rg-1, comes to about $1,567. The cheapest option here, Residential Seasonal Rg-1, comes to $1,366 — a gap of about $201 a year for a household that never changed a single habit. Whether you can actually capture that depends on when you use power, which is what the calculator below is for.
2 of these 4 plans price by the hour. Those are the ones where moving laundry, dishes, or car charging into the cheap window changes the bill; on the rest, the clock is irrelevant and only the total matters. Which camp you belong in is the first question worth settling, because it decides whether shifting your day is worth anything at all.
Watch the fixed charges too. Across these plans they run from $14 to $215 a year before a single kilowatt-hour is counted. For a small household that difference alone can outweigh the per-kWh price, which is why comparing cents per kilowatt-hour on its own quietly misleads.
How Wisconsin Public Service compares across Wisconsin
Run the same three-bedroom house with central air through its default plan at each of the 6 Wisconsin utilities we cover, and Wisconsin Public Service comes in 3rd cheapest at about $1,567 a year; the state median is $1,650. The range runs from $1,209 at Superior Water and Light to $2,032 at Wisconsin Electric Power, and since the utility is set by the address, the part of that gap you can act on is the plan, not the company.
The other two households tell the same story in different sizes: a small apartment pays about $911 here against a state median of $945, and the same house with an electric car charging overnight about $2,089 against $2,211. Effective rate, fixed charge included, is 16.6¢ per kilowatt-hour for the family home.
Inside Wisconsin Public Service itself, the gap between its cheapest and dearest plan for that house is $325 a year — less than the $823 between Wisconsin's cheapest and dearest utilities. Here the address decides most of the bill; the plan decides the rest.

Same usage, different plan
$274a year
That is the gap between the cheapest plan you could be on — Residential Seasonal Rg-1 — and the priciest. Not by using less power. By being billed differently for the same power.
| Plan | Per year | Vs best |
|---|---|---|
| Residential Seasonal Rg-1One rate, every hour of the year. | $1,476 | — |
| Residential Seasonal Three-tier Time-of-Use Rg5-OTOUPeak hits 4pm–8pm in Oct–Apr, 1pm–7pm in May–Sep — on weekdays. | $1,549 | +$73 |

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.
