Consumers Energy Peak Hours Guide: Summer Rates and How to Save
Consumers Energy uses time-of-day pricing, so electricity costs more during certain weekday hours. For Michigan households, the biggest difference comes during the summer, when afternoon electricity rates are higher than off-peak rates. Knowing the schedule can help you plan everyday tasks around those higher-cost hours. You might run the dishwasher or laundry earlier in the day, wait until evening, or adjust the thermostat during the afternoon peak.
Consumers Energy's current summer peak hours
Consumers Energy's summer schedule is fairly simple, but the timing matters if you're trying to keep your electricity costs down. The biggest difference shows up during the weekday afternoon window, when the on-peak rate is higher.
Summer peak window
Summer peak hours run 2 p.m. to 7 p.m., Monday through Friday, from June 1 through September 30. During these five hours, electricity costs more than it does during off-peak periods. This is the main window to watch if you're trying to reduce higher-rate electricity use. Weekends remain off peak all day during the summer. You can use that flexibility to run larger household loads, such as laundry or the dishwasher, without putting them in the weekday afternoon peak period.
Summer electricity rates
For the 2026 summer rate, on-peak electricity costs about 24.5 cents per kWh, compared with roughly 19.7 cents per kWh off peak. That difference can add up if your home uses a lot of electricity during the afternoon, especially for cooling and other high-use appliances. You can compare these rates with the average Michigan electric bill to get a better sense of how they fit into typical household costs. Outside the summer window, the rate difference becomes much smaller.
Winter peak hours and rate differences
Understanding your winter electricity bill depends on which Consumers Energy rate plan you use. Rate RS has no weekday peak period during winter, while Smart Hours Rate RSP continues to use time-based pricing. This difference affects when shifting electricity use can help lower costs.
Standard Summer Rate (Rate RS): All-day flat pricing in winter
If you are on Consumers Energy's standard residential plan (Rate RS), there are no weekday peak hours during the winter. From October 1 through May 31, the summer peak window turns off completely. Electricity returns to a flat non-peak rate throughout the day. You do not need to restrict high-energy appliance use between 2 p.m. and 7 p.m. during winter months under Rate RS.
Smart Hours Rate (Rate RSP): Year-round peak pricing
For customers who opt into the Smart Hours Rate (Rate RSP), time-of-use pricing remains active throughout the year:
Winter peak window: Weekdays from 2 p.m. to 7 p.m., from October 1 through May 31.
Winter rate differences: The price difference between winter peak and off-peak hours under Rate RSP is much smaller than the summer spread, at roughly one cent per kWh.
Impact: Because the winter price gap is relatively small, shifting appliance use outside the 2 p.m. to 7 p.m. window generally produces less bill savings than shifting usage during the summer peak period.
Shifting summer usage with stored power
A battery can help you change when you use electricity. Charge it during lower-cost hours. Then use the stored power during Consumers Energy's 2 p.m. to 7 p.m. summer peak window. This can be useful for homes with central AC. Cooling can use a lot of electricity during hot Michigan afternoons.
For households that don't need a whole-home battery, a portable power station offers a simpler way to shift some electricity use. The EcoFlow DELTA 3 Ultra can store power during lower-cost hours and provide it later for appliances and other essential devices.
With the rate structure clear, it also helps to understand why Consumers Energy uses peak pricing in the first place. That explains why shifting electricity use away from those hours can help.
Why the Michigan Public Service Commission Requires This
Michigan's time-of-day pricing is designed to encourage households to use less electricity during periods when demand is higher. The Michigan Public Service Commission directed major utilities to move residential customers toward this pricing structure.
Shifting demand away from peak hours
The goal is to spread electricity use across more hours of the day instead of having too much demand at once. This can reduce pressure on the grid during the busiest periods. For households, that can mean moving flexible tasks such as laundry or dishwashing to hours when electricity demand is lower.
When household demand overlaps
Consumers Energy has said the pricing structure is intended to reduce strain when air conditioning, dinner preparation, laundry, and other household loads happen around the same time. Moving some of these activities outside peak hours can help spread that demand.
How other Michigan utilities compare
Consumers Energy isn't the only major Michigan utility using time-of-day pricing. DTE Energy uses a similar approach, with a slightly different 3 p.m. to 7 p.m. peak window. The comparison shows that Michigan utilities can use different peak schedules while following the same basic approach of encouraging customers to shift some electricity use away from higher-demand periods.
Estimate the impact on your bill
Knowing an appliance's energy use can help you see whether moving it outside peak hours is worth it. Use this guide to calculate kWh usage and estimate the potential impact of shifting specific appliances. With the reasoning clear, a few practical changes can make the biggest difference in an actual bill.
Practical ways to lower a Consumers Energy bill
You don't have to change your entire routine to lower your electricity costs. A few small shifts during the summer peak window can help you use less power when rates are higher. Start with tasks that are easy to move without affecting your daily routine.
Shift laundry and dishwashing
Run the dishwasher and washing machine before 2 p.m. or after 7 p.m. during the summer. These appliances are usually easy to schedule, especially if they have delay-start settings. Moving these loads outside the peak window lets you keep using the same appliances without paying the higher summer rate for that electricity.
Adjust the thermostat
Raise the thermostat a few degrees during the 2 p.m. to 7 p.m. peak period rather than keeping it higher all day. This can reduce cooling demand when electricity costs more. Once the peak window ends, you can return the thermostat to your usual setting. That gives you a way to limit afternoon energy use without changing your home's temperature for the entire day.
Prioritize high-use appliances
Not every appliance affects your bill by the same amount. Focus first on equipment that uses more electricity or runs for longer periods, especially during the 2 p.m. to 7 p.m. peak window. Knowing how amps, volts, and watts relate can help you estimate which appliances use the most power and are worth shifting to off-peak hours.
Conclusion
Consumers Energy's summer peak hours run 2 p.m. to 7 p.m., Monday through Friday, from June through September. The 2026 on-peak rate is about 24% higher than the off-peak rate. Shifting laundry, dishwashing, and thermostat use can help reduce higher-rate electricity use. For more control, the EcoFlow DELTA Pro Ultra X and EcoFlow DELTA 3 Ultra can store power during lower-cost hours. You can then use that stored power during the summer peak window. This can reduce your reliance on higher-rate electricity.
