What does Residential Service Demand Rd-1 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 | $70 | $840 | 17.3¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $130 | $1,555 | 16.4¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $156 | $1,872 | 14.3¢ / 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 | 25.50¢ | 5pm–9pm, December–February; 11am–7pm, June–August |
| mid | 17.50¢ | 6am–5pm, 9pm–11pm, December–February; 6am–11pm, March–May, September–November; 6am–11am, 7pm–11pm, June–August |
| off-peak | 8.70¢ | 11pm–6am, midnight–midnight |
Plus a fixed charge of $0.3288 per day — so longer months cost more before you use a single kWh.
Should you be on Residential Service Demand Rd-1?
This plan bills a demand charge on top of the per-kWh rates: a fee tied to your single highest hour of the month. Two homes using the same total electricity can pay very different amounts if one of them runs the dryer, the oven, and the car charger at the same moment. We do not price demand charges yet, so treat every dollar figure on this page as a floor, not a total.
Before a single kilowatt-hour moves, this plan charges $120 a year in fixed fees. On the apartment above that is 14% of the whole bill; on the house with a car charging in it, 6%. 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 $199 in July and $100 in November — a $99 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.
Other Wisconsin Power & Light plans
Who can be on Wisconsin Power & Light’s Residential Service Demand Rd-1 (Single Phase)?
Eligibility is not our judgement — it is written into the tariff Wisconsin Power & Light filed. This is what that document says:
This schedule is available to all residential customers who use single or threephase service and have Measured Maximum Demands of 75 kW or less for at least 8 out of 12 months and annual energy usage of 250,000 kWh or less. For new customers, the company shall, at its discretion, determine the customer�s demand limits and energy usage until review of 12 month�s service.
Shortened — the clause runs longer in the filing. Quoted from the filed tariff. Your utility decides eligibility, not us; check with them before you switch.

A dozen brutally expensive afternoons a year, in exchange for a discount on the other 353 days.
- Why is my electric bill so high in summer?
Usually three causes at once, and only one of them is your air conditioner.
