Time-of-Use Electricity Rates Explained: Can They Actually Save You Money?
Quick Answers
Who benefits most from time-of-use rates?
Households with flexible schedules — especially those charging an EV at home overnight or able to run major appliances during off-peak windows.
Who should be cautious?
Households that work from home and use significant AC or heating during peak afternoon hours may see costs rise rather than fall.
Is switching mandatory?
In most markets it's optional, though some utilities are shifting toward time-of-use as the default rate structure.
The basic mechanism
Instead of one flat rate all day, time-of-use plans charge a higher rate during peak hours (often late afternoon into evening) and a lower rate overnight and midday in some regions.
Where the savings actually come from
The savings aren't automatic — they come specifically from shifting controllable usage (laundry, dishwashing, EV charging) away from the expensive peak window.
When to skip it
If your household's biggest usage (AC, heating, remote work equipment) happens to fall during peak hours and can't realistically shift, a flat rate may serve you better.
