We Energies (Wisconsin Electric Power) runs one of the simplest TOU rates on this list, a flat 23.4¢/kWh peak and 10.7¢/kWh off-peak, no seasonal changes at all. What’s unusual is the utility lets residential customers choose which 12-hour block counts as their own peak window.
We Energies' peak rate never changes by season, only by which window option you pick. Look up the details for your plan.
See my peak hours →Residential Time-of-Use (Rg 2): Four Window Options
| Option | Peak hours | Off-peak hours | Rate (either window) |
|---|---|---|---|
| A | 7am–7pm | 7pm–7am | 23.4¢/kWh peak, 10.7¢/kWh off-peak |
| B | 8am–8pm | 8pm–8am | Same rates |
| C | 9am–9pm | 9pm–9am | Same rates |
| D | 10am–10pm | 10pm–10am | Same rates |
All four options split the day into two equal 12-hour halves at the exact same peak and off-peak rate, they just differ in where the boundary falls. A household with an early schedule (up at 6, in bed by 9) might prefer Option A, so their evening wind-down after 7pm already counts as off-peak. A household with a later routine might do better on Option D, pushing the off-peak start to 10pm to match when they’d realistically shift usage anyway.
This same rate and structure applies whether you’re on single-phase or three-phase residential service, the four window choices work identically either way.
What Shifting Is Worth, in Dollars
Take an evening routine: dishwasher and laundry, about 4 kWh, run during whichever 12-hour block is your chosen peak window.
At peak: 4 kWh × $0.234 = $0.94 Same load shifted to off-peak: 4 kWh × $0.107 = $0.43
That’s $0.51 saved per shifted routine, a 54% cut, all year round with no seasonal exceptions to track. Over 300 days a year, consistently avoiding your 12-hour peak window for one daily routine is worth roughly $153/year.
Picking the Right Window Matters More Than Shifting Habits
Because the rate is identical across all four options, the single most impactful decision on this plan isn’t a daily habit, it’s choosing the window option that best matches when your household is naturally least active. Someone who picks Option A but actually runs their dishwasher at 7:30am every morning (just inside peak) is leaving money on the table that Option D would have captured automatically.
Should You Switch to Time-of-Use?
A flat, year-round 2.2x spread with no seasonal complexity makes this one of the more predictable plans on this list to evaluate. The main decision is matching your existing routine to one of the four window options rather than trying to change your routine at all, this plan rewards picking correctly more than it rewards behavior change.
